Background: The Continuous Traumatic Stress Response scale (CTSR) was designed to measure symptoms associated with multiple ongoing security threats in the context of Israeli-Palestinian conflict. Since 2014, Ukraine has faced armed invasion and war, with nationwide insecurity since February 2022.Objective: This study aimed to adapt the CTSR scale into Ukrainian and evaluate its psychometric properties within a Ukrainian sample during the ongoing war.Method: The Ukrainian adaptation of the CTSR followed the procedure used in creating the original instrument (Goral, A., Feder-Bubis, P., Lahad, M., Galea, S., O'Rourke, N., & Aharonson-Daniel, L. (2021). Development and validation of the Continuous Traumatic Stress Response scale (CTSR) among adults exposed to ongoing security threats. PLoS One, 16(5), e0251724). To identify a unique context-specific factor structure relevant to the Ukrainian experience, the initial 25 items were tested in a sample of 584 Ukrainians using exploratory and confirmatory factor analyses. Subsequently, the established scale structure was assessed for homogeneity, and convergent validity using measures of depression (PHQ-9), anxiety (GAD-7), perceived stress (PSS-4), resilience (BRS), and PTSD symptoms (PCL-5).Results: A three-factor, 9-item solution, representing the constructs of exhaustion, alienation, and helplessness, demonstrated the most acceptable fit among all the alternative CTSR models, including the original: χ2 = 72.84, df = 24, p < .001, χ2/ (df) = 3.04, CFI = 0.94, TLI = 0.91, SRMR = 0.05, RMSEA = 0.08. Cronbach's α for internal consistency ranged from 0.68 to 0.84 for total score, and subscales. Significant positive correlations ranging from 0.41 to 0.67 with symptom severity of depression, anxiety, perceived stress, and PTSD established the convergent validity of the Ukrainian CTSR, indicating that it measures related yet distinctive psychological phenomena of reactions to continuous traumatic stress.Conclusions: The revised Ukrainian version of the CTSR scale is a reliable and valid measure of continuous traumatic stress response, accurately reflecting its manifestation in the Ukrainian context. These findings are crucial for guiding clinical interventions and research in prolonged war environments, where understanding the nuances of ongoing trauma is essential.

Background: A number of studies have tested the factor structure of the suggested ICD-11 symptom criteria for PTSD and complex PTSD (CPTSD) across various trauma populations, finding support for two different models in line with the ICD-11 theoretical rationale.Objective: Here, we aim to explore the factor structure of the Danish version of the International Trauma Questionnaire (ITQ) by testing two alternative factor models that have previously gained support in a large sample of treatment-seeking veterans.Method: Treatment-seeking Danish soldiers and veterans (N = 599) recruited from the Military Psychology Department in the Danish Defence completed the International Trauma Questionnaire (ITQ). Confirmatory factor analysis (CFA) was used to assess fit of a first-order and a second-order model.Results: Both models fit the data well but displayed latent variable correlations above 1 and negative variances (known as Heywood cases), indicating model misspecification or other problems. The specification problems included the latent variable Affect Dysregulation.Conclusions: Based on our results and results reported in previous CFAs of the ITQ, we suggest consideration of the proposed models. While many previous studies did find support for the models with no indications of misfit, others find Heywood cases concerning the same items and latent variables as our analysis. Hence, models of (C)PTSD based on the ITQ should be carefully evaluated and interpreted.

Adverse childhood experiences (ACEs) are linked to later anxiety and depression, and inflammation has been implicated as a mediating mechanism. Black and Latinx men who have sex with men (MSM) face higher prevalences of ACEs, anxiety, and depression compared to White, heterosexual peers. Understanding the links between ACEs and mental health is crucial to addressing these disparities.

This study used structural equation modeling to test moderated mediation models examining inflammation as a mediator of the relationship between ACEs and symptoms of anxiety/depression and minority stress as a moderator on the path between ACEs and inflammation. Data was from a community sample of Black and Latinx MSM (n = 246; mean age = 22.6).

ACEs were significantly associated with symptoms of anxiety (B = 0.414; p < 0.001) and depression (B = 0.346; p < 0.001), but inflammation did not show a significant mediating effect. Additionally, the interaction between ACEs and minority stress had no significant indirect effect on anxiety/depression.

These findings underscore the possibility that inflammation may not represent the global perturbations of stress processes after ACEs at younger ages, particularly among a relatively healthy sample of emerging adults.

The Difficulties in Emotion Regulation Scale (DERS) is frequently used to assess emotion regulation (ER) capabilities. Originally a multidimensional scale, many utilize its total score, without clear recommendations. We aimed to explore the DERS's structure, dimensionality, and utility and provide clinicians and researchers with clear guidelines. Self-report data on ER, personality, psychopathology, and life satisfaction were collected from 502 adults. Seventy also participated in a lab study evaluating group interactions, which included additional self-report and physiological monitoring. Findings suggested favoring the correlated-traits and bifactor models, the latter excelling in direct comparisons. The total score was found reliable and valid, explaining 53.3% of the variance, with a distinct emotional awareness subfactor, suggesting a non-pure unidimensional solution. A cutoff score of 95 identified significant ER difficulties, linked to psychopathology. We thus recommend using the DERS's total score and 95 as its cutoff, while calling for further validation in diverse and clinical samples.

Quality of life (QOL) is important for evaluating medical care outcomes. In chronic kidney disease (CKD) population, generic instruments, such as WHOQOL-BREF and EQ-5D, are commonly used for comparing various medical conditions for policy-making purposes. However, their psychometric properties have not yet been validated in non-dialysis CKD population.

Patients who were in CKD care programs at a medical center in Taiwan were recruited and self-filled WHOQOL-BREF Taiwan version (TW) and EQ-5D questionnaires. Rasch model, confirmatory factor analysis (CFA), and Pearson correlations were used to validate psychometric properties of these two QOL instruments.

634 participants, aged 66 ± 14 years old, were enrolled. Rasch model revealed almost all items (23 of 26) in WHOQOL-BREF (TW) and all items in EQ-5D were well-fit in their domains. Both instruments demonstrated relatively robust psychometric properties in CFA and Rasch analysis, with WHOQOL-BREF (TW) performing slightly better. Fewer items in WHOQOL-BREF (TW) displayed substantial differential item functioning compared to EQ-5D, particularly across different CKD stages (1 or 2 of 26 versus 4 of 5), diabetes mellitus (DM) and non-DM status (1 of 26 versus 4 of 5), and different age groups. The original domain scores/utility scores were highly correlated with Rasch scores (all absolute correlation coefficients >0.90).

Both WHOQOL-BREF (TW) and EQ-5D have relatively good psychometric properties in non-dialysis CKD population. The direct use of original WHOQOL-BREF (TW) domain scores/EQ-5D utility score for parametric analyses is acceptable in non-dialysis CKD population. However, when using the EQ-5D for cost-effective comparison in CKD patients with different stages or characteristics potential bias should be concerned.

The childbirth experience and birth-related trauma are influenced by various factors, including country, healthcare system, a woman's history of traumatic experiences, and the study's design and instruments. This study aimed to validate the City Birth Trauma scale for Lithuanian women post-childbirth. Using a descriptive, cross-sectional survey with a nonprobability sample of 794 women who gave birth from 2020-2021, the study found good validity, reliability, and presented the prevalence of birth-related stress symptoms. A bifactor model, consisting of a general birth trauma factor and two specific factors for birth-related symptoms and general symptoms of PTSD, showed the best model fit. The Lithuanian version of the City Birth Trauma scale can be effectively used in research and clinical practice to identify birth-related trauma symptoms in women after giving birth.

The Upper Limb Functional Index (ULFI) is a robust, widely used tool for assessing the functional status of the upper limbs (ULs) and the effectiveness of interventions in patients with musculoskeletal disorders (MSDs). This study aimed to translate and culturally adapt the ULFI into Polish (ULFI-PL) and evaluate its psychometric properties and practical characteristics.

A total of 127 patients (54% female, x ¯  = 45.07 ± 14.97 years) with various ULMSDs and symptom durations completed the ULFI-PL, the shortened Disabilities of the Arm, Shoulder, and Hand questionnaire-Polish version (QuickDASH-PL), the Polish version of the World Health Organization Quality of Life-BREF (WHOQOL-BREF-PL), Numeric Pain Rating Scale (NPRS), and the seven-point Global Rating of Change (GRC) scale. The internal consistency, construct validity, and factor structure were assessed in all the participants; the test-retest reliability and measurement error were evaluated in a subgroup (n = 112, 2-3-day interval); and the responsiveness and interpretability were evaluated in another subgroup (n = 56, 8-week interval, after physiotherapy).

The ULFI-PL demonstrated a good internal consistency (α = 0.77) and high construct validity, supported by the confirmation of five out of six a priori hypotheses (83.33%). A confirmatory factor analysis (CFA) revealed a unidimensional structure. It also demonstrated a high test-retest reliability (r = 0.85). The measurement error was calculated using the standard error of measurement (SEM = 4.75%) and the minimal detectable change (MDC95 = 13.17%). The ULFI-PL showed a high responsiveness after physiotherapy, which was confirmed by the effect size (ES = 2.08) and the standardized response mean (SRM = 1.88). The minimal clinically important difference (MCID) for the ULFI-PL was 28.29% (95% CI: 24.96-31.63).

The ULFI-PL is a reliable, valid, and responsive tool for assessing the upper limb function in Polish-speaking patients with ULMSDs and is suitable for use in both clinical and research contexts. The results are consistent with previous studies on the original English version and other language adaptations.

Children and adolescents with an intellectual disability (ID) show increased rates of emotional and behavioural problems, presenting significant challenges for the afflicted individuals, their families, and their teachers. The teacher version of the Developmental Behaviour Checklist (DBC-T) is a reliable and valid questionnaire comprising 94 items that assess emotional and behavioural problems in children and adolescents with ID.

The present study aimed to develop and validate a short form of the German DBC-T that retains the structure and the good psychometric properties of the full version, thereby allowing for the interpretation of the subscale scores.

Data were obtained from a longitudinal study involving 397 teacher staff members who reported on 1177 children and adolescents with ID at two time points during one school year (T1, T2). The full version of the DBC-T was shortened in a two-stage process based on data from T1. The reliability of the subscales of the short form and various aspects of construct validity were evaluated using data from T1 and T2.

A short form of 35 items was developed. The factor structure was confirmed at both T1 and T2. The five subscales demonstrated good internal consistency. The findings indicated both discriminant and convergent validity in relation to adaptive behaviour, as well as known-group validity concerning gender and age.

The proposed short form complements the full version of the DBC-T and offers a time-efficient means of assessing multiple students simultaneously, as often required in school and research contexts. WHAT THIS PAPER ADDS?: This study develops and validates a short form of the German Developmental Behaviour Checklist (DBC-T) that assess emotional and behavioural problems in children and adolescents with intellectual disability. The proposed short form retains the subscale format of the DBC-T, allowing for interpretation of the subscale scores. The short form demonstrated good psychometric properties. As a reliable, valid and time-efficient instrument, the short version may supplement the full version.

To explore content validity, construct validity, and reliability of anchor questions used to determine minimal important change (MIC), patient acceptable symptom state (PASS) and treatment failure (TF) in patients undergoing knee or hip arthroplasty.

A mixed-methods study from one public hospital. Evaluation of content validity involved applying thematic analysis to data from think-aloud interviews. To ascertain construct validity and reliability, we focused on patients who underwent surgery between 2016 and 2022 and had responded to preoperative and either 3-, 12- or 24-month postoperative questionnaires. Confirmatory factor analysis (CFA) was employed to assess present state bias (PSB), model fit, and reliability of the anchor questions.

We conducted 18 interviews with patients aged 52 to 84 (10 female). Based on seven emerging themes from the content validity analysis, MIC and PASS anchor questions were considered relevant and comprehensible, while the TF anchor question had several problems. Data from 1197 to 2207 patients, with 3-, 12-, or 24-month postoperative responses, were used to evaluate construct validity. The median age was 69-70 years (56-59% female). PSB for MIC was between 54 and 73%, and reliability for the anchor questions was between 0.52 and 0.80 for all time points. The CFA models varied between good and poor fit.

The MIC and PASS anchor questions demonstrated a high degree of content validity, while it was questionable for TF. Construct validity was considered good to poor for PASS, but patients may consider their present state more than their preoperative state when responding to the MIC. Reliability was considered acceptable in both MIC and PASS.

In clinical practice and research, self-report instruments are frequently used for assessing the severity of borderline personality disorder (BPD) symptomatology experienced by men and women. Men with BPD are often underrepresented in samples used to evaluate self-report questionnaires. Measurement invariance (MI) is used to examine whether self-report questionnaires determine the same latent construct across groups or varying conditions (e.g., measurement occasions).

The present study investigated measurement invariance for two self-report measures of BPD features: the Borderline Symptom List (BSL-23) and the Impulsivity and Emotion Dysregulation Scale (IES-27). An inpatient sample of N = 3507 individuals (n = 560 males) was used to test for measurement variance between males and females, and over time from pre- to post-treatment.

Confirmatory factor analysis results supported a unidimensional structure for the BSL-23 and a three-factor model for the IES-27. Both instruments were found to be measurement invariant with regard to sex and time.

The results suggest that the BSL-23 and IES-27 can be used to assess BPD symptoms in men and women, as well as to assess treatment effects at admission and at the end of treatment.

The use of the internet has become an increasingly integral part of individuals' daily lives, bringing negative consequences such as internet addiction. Understanding the motivations behind internet use is crucial for preventing addiction and developing effective intervention strategies. The objectives of this study are to test the validity and reliability of the Questionnaire of Internet Use Motives (MUI) among Turkish adults and to investigate the predictive effects of socio-demographic variables and internet use motivations on internet addiction. The study was conducted with a sample of 640 adults selected through convenience sampling at two different time points. The majority of participants were women, highly educated, and from a middle socioeconomic background. Data were collected using a socio-demographic questionnaire, the Questionnaire of Internet Use Motives (MUI), and the Internet Addiction Test (IAT). To evaluate the structural validity of the scale, a Confirmatory Factor Analysis (CFA) was performed. Additionally, measurement invariance across genders was examined, and Hierarchical Multiple Linear Regression Analyses were conducted to identify predictors of internet addiction. CFA confirmed the structural validity of the MUI, revealing a five-factor structure with a good fit to the data. The five identified motives were enhancement, coping, social, conformity, and utility. The analyses also demonstrated that the scale possesses convergent and discriminant validity, as well as high reliability. Furthermore, the instrument exhibited measurement invariance across genders. Significant predictors of internet addiction included educational level, socioeconomic status, and the enhancement, social, coping, and conformity motives. The validated MUI provides a robust tool for assessing internet use motives in Turkish adults, offering a foundation for future research and intervention development. Addressing psychological motives such as enhancement, social, coping, and conformity in prevention and treatment strategies may reinforce efforts to mitigate problematic internet use.

The Dual Continua Model (DCM) views mental health and mental illness as two separate but related constructs. The current study was designed to assess the factor structure and concurrent validity of this DCM with an intercollegiate sport sample. The 2022 Canadian cohort (N = 345; 65% female) of the National College Health Assessment completed the Mental Health Continuum-Short Form, the Kessler K6, the Connor Davidson Resilience Scale, and the UCLA Loneliness Scale. A Confirmatory Factor Analysis of obliquely related factors of mental health and illness showed strong fit of the model to the data (CFI = 0.997; RMSEA = 0.027). ANOVAs comparing different sub-groups within the DCM showed that resilience and loneliness differed among groups according to their levels of mental health and/or illness in manners consistent with the model.

Rotator cuff-related shoulder pain (RCRSP) is a common musculoskeletal disorder. Chronic symptoms, high-level pain intensity, and disability are associated with high levels of pain catastrophizing in this condition. Although the Pain Catastrophizing Scale (PCS) is widely used to assess pain catastrophizing in individuals with chronic symptoms, its measurement properties are still unknown for assessing individuals with chronic RCRSP.

To assess construct validity, reliability, and responsiveness of the PCS in individuals with chronic RCRSP.

Eighty-three adult individuals with chronic RCRSP were included in this study. The assessment of construct validity was based on hypothesis testing. Spearman's rank correlation coefficient was used to verify the correlation of the total score and rumination, magnification, and helplessness subscales of the PCS with pain intensity, disability, and fear of movement. Test-retest reliability was analyzed with Intraclass Correlation Coefficient (ICC)(3,1) and internal consistency was analyzed with Cronbach's alpha. Responsiveness was analyzed by effect sizes and the area under the receiver operating characteristic curve (AUC).

The PCS showed significant moderate correlation (rho ≥ 0.40) with fear of movement (95% confidence interval [CI]: 0.23, 0.70), pain intensity (95% CI: 0.14, 0.64), and disability (95% CI: 0.17, 0.66), except the rumination and magnification subscales, which showed significant weak correlation with pain intensity (95% CI: 0.14, 0.58) and disability (95% CI: 0.12, 0.56), respectively. PCS presented good reliability (ICC > 0.7, 95% CI: 0.63, 0.88), and adequate internal consistency (Cronbach alfa > 0.7) and responsiveness based on effect sizes and AUC.

The PCS is a valid, reliable, and responsive instrument for assessing individuals with chronic RCRSP.

The use of oral anticancer agents (OAAs) has increased in recent decades. Despite the advantages of OAAs, people with cancer face challenges such as adherence, prevention, recognition, and management of OAA side effects. Informal caregivers can help their patients who take OAAs by facing the above challenges with the implementation of behaviours to maintain stability (Caregiver contribution to self-care maintenance), monitoring (Caregiver contribution to self-care monitoring) and managing (Caregiver contribution to self-care management) the conditions of their patients.

To develop and test the psychometric properties of the Caregiver Contribution to self-care in the Oral Anticancer Agents Index (CC-SCOAAI).

A longitudinal study was conducted. Factorial validity was tested using Confirmatory Factor Analysis (CFA). Furthermore, we also tested the internal consistency and validity of the CC-SCOAAI construct. The Mann-Whitney U test was used to demonstrate associations between CC-SCOAAI scores and patient's re-hospitalizations, emergency-room attendances, and mortality.

We enrolled 318 caregivers, mostly female (63.52 %), with an age of <44 (39.94 %) and spouse of the patient (54.66 %). The CFA demonstrated the factorial validity of the CC-SCOAAI. Caregivers of patients with more re-hospitalizations had a lower contribution to self-care maintenance (U = 2933.500; p = .04), while caregivers of patients with more emergency room admissions (U = 1392.500; p < .001) and re-hospitalizations (U = 2385.500; p < .001) had a lower contribution to self-care management. Caregivers of patients with emergency-room admissions (U = 1392.500; p = .005), re-hospitalisations (U = 2322.500; p < .001) and mortality (U = 515.500; p = .001) had lower contribution to self-care monitoring.

CC-SCOAAI is a valid and reliable tool. Given that caregivers are crucial in supporting these patients, the CC-SCOAAI may help clinicians improve caregiver efficacy and researchers using CC-SCOAAI to determine better self-care outcomes in patients with OAA.

Schools conduct comprehensive psychoeducational evaluations to identify students with specific learning disabilities (SLDs) and determine whether they qualify for special education services. This decision-making process is complex and research has documented many factors influencing SLD identification decisions. One such factor may be decision-makers' beliefs about the underlying causes of SLD, including intrinsic and extrinsic factors. However, no studies to date have examined the underlying factor structure of the responses to prompts about the causes of SLD from intrinsic and extrinsic perspectives. This study was conducted with a sample of 521 U.S. school psychologists as part of a larger study examining decision-making during SLD identification. Using confirmatory factor analyses (CFA) to compare two theoretically plausible models, results suggested that a single latent factor best captured variability in responses to these prompts. Implications for assessing beliefs and how they impact the psychoeducational assessment process to identify SLDs are discussed, along with areas for future research.

Background/Objectives: The complexity of modern healthcare requires teamwork. Healthcare teams must be cohesive to ensure efficient and quality care. The objective of this study was to validate the Spanish short version of the Group Environment Questionnaire (GEQ) in undergraduate nursing students undergoing clinical simulation training. Methods: The psychometric properties of the questionnaire were analyzed. We began with a statistical analysis of the items. Internal consistency was assessed using McDonald's omega coefficient. Test-retest reliability was determined using Spearman's correlation coefficient. An exploratory factor analysis was performed using the principal components analysis method with varimax rotation. Finally, a confirmatory factor analysis of the proposed theoretical models was performed to select the most appropriate one using the weighted least squares method adjusted for mean and variance (WLSMV) and goodness-of-fit indices. Results: The questionnaire items showed a standard deviation higher than 1 and a negative skewness lower than 0.5. Internal consistency and test-retest reliability were higher than 0.8. The item-total correlation coefficient values were above 0.44. The exploratory factor analysis confirmed the presence of four factors, each with three items. Confirmatory factor analysis determined that the four-factor cohesion model was the one that obtained the best fit. Conclusions: The Spanish short version of the Group Environment Questionnaire (GEQ) is a valid and reliable instrument for analyzing group cohesion in teams of nursing students undergoing clinical simulation training.

Existent research examining perceptions of nicotine addiction use largely surface level items that fail to address the complexity of nicotine addiction. Additional investigation is needed to better understand people's perceptions of nicotine addiction and whether these align with measures of nicotine dependence. Understanding these perceptions about nicotine addiction may help provide insight into vaping intentions and behavior. This study examines the validity of the Nicotine Addiction Perceptions (NAP) scale, a novel measure designed to assess perceptions of addictive vaping behavior that aligns with the clinical dimensions of tobacco use disorder.

Data were collected from U.S. adults via Prolific (n = 549). As part of scale development and validation a confirmatory factor analysis and psychometric evaluation was conducted. The NAP's reliability, convergent, discriminant, and criterion validity were established.

A five-factor solution returned acceptable fit on all model indices (RMSEA = 0.050; CFI = 0.994; TLI = 0.993). The NAP was significantly related to assessments of perceived risk, 6 month quit intentions, the number of quit intentions over the past year, and past 30-day e-cigarette use (P's < .05). Findings also indicate support for discriminant validity.

Findings suggest that for most, perceptions of nicotine addiction may not fully align with the clinical criteria of addiction, which may be due to the lack of education surrounding the clinical definition. Future research examining perceptions of nicotine addiction can utilize the NAP scale to better understand people's understanding of addiction and its relationship to vaping-related behavior.

This paper explores the efficacy of AI-driven chatbots in accurately inferring personality traits compared to traditional psychometric tests within a real-world professional hiring context. The study is driven by the increasing integration of AI tools in recruitment processes, which necessitates a deeper understanding of their reliability and validity. Using a quasi-experimental design with propensity score matching, we analysed data from 159 candidates and other professionals from Serbian and Montenegrin regions who completed both traditional psychometric assessments and AI-based personality evaluations based on the Big Five Personality model. A novel one-question-per-facet approach was employed in the chatbot assessments with a goal of enabling more granular analysis of the chatbot's psychometric properties. The findings indicate that the chatbot demonstrated good structural, substantive, and convergent validity for certain traits, particularly Extraversion and Conscientiousness, but not for Neuroticism, Agreeableness, and Openness. While robust regression confirmed that AI-inferred scores are less susceptible to social desirability bias than traditional tests, they did not significantly predict real-world outcomes, indicating issues with external validity, particularly predictive validity. The results suggest that AI-driven chatbots show promise for identifying certain personality traits and demonstrate resistance to social desirability bias. This paper contributes to the emerging field of AI and psychometrics by offering insights into the potential and limitations of AI tools in professional selection, while developing an approach for refining psychometric properties of AI-driven assessments.

We present a novel approach for computing model scores for ordinal factor models, that is, graded response models (GRMs) fitted with a limited information (LI) estimator. The method makes it possible to compute score-based tests for parameter instability for ordinal factor models. This way, rapid execution of numerous parameter instability tests for multidimensional item response theory (MIRT) models is facilitated. We present a comparative analysis of the performance of the proposed score-based tests for ordinal factor models in comparison to tests for GRMs fitted with a full information (FI) estimator. The new method has a good Type I error rate, high power and is computationally faster than FI estimation. We further illustrate that the proposed method works well with complex models in real data applications. The method is implemented in the lavaan package in R.

Dysfunctional metacognitive beliefs have been established as a transdiagnostic correlate of anxiety and depression in adults and are considered a central mechanism of persistent emotional distress according to the metacognitive model of psychological disorders. However, the importance of metacognitions for distress and emotional disorder in adolescence is far less researched, and to investigate this further there is a need for reliable and valid assessment tools. The Metacognitions Questionnaire-30 (MCQ-30) might be a suitable and valid assessment tool in adolescents with the implication that it can be used to research the role of metacognitions in youth mental health and track how metacognitions change and relate to outcomes over time from adolescence to adulthood. We therefore aimed to examine the psychometric properties of the MCQ-30 in an Upper Secondary School-sample of 494 Norwegian adolescents, aged 16- to 18-years old. A confirmatory factor analysis indicated a good fit for the proposed five-factor structure and evidence for measurement invariance was supported across sex and groups of anxiety severity. The factors showed acceptable to good internal consistency and there was support for convergent validity. In conclusion, these findings indicate that the adult version of the MCQ-30 can be applied in Norwegian adolescents from 16-years old.

Background/Objectives: Discrimination is a phenomenon of special relevance in adolescence, as this is a key period in the development of young people, so measures that accurately and reliably assess it are essential. The aim of this research is to study the psychometric properties of the Spanish version of the Everyday Discrimination Scale in a sample of Spanish adolescents. Methods: The scale was applied to 1000 adolescents using Computer Assistance Web Interview (CAWI) methodology by means of a stratified random sampling by age, gender and territorial distribution. Results: The results reveal an unifactorial structure of the scale, with adequate measures of reliability and validity that confirm that it is a suitable instrument for assessing everyday discrimination in this population. Conclusions: This study has implications for understanding the experiences of discrimination in adolescents and for developing interventions to reduce discrimination and promote equality. Limitations and implications for the future are also discussed.

Previous research has demonstrated a correlation between nursing students' self-efficacy and their clinical performance, competence, and behavior during clinical practice placements. Assessing students' self-efficacy in clinical performance could be a valuable method for identifying areas that need reinforcement and for recognizing students who may require additional support during clinical practice placements.

This study aimed to translate the Self-Efficacy in Clinical Performance Scale (SECP) from English into Norwegian and to evaluate the psychometric properties of the Norwegian version.

A cross-sectional study design was used. The SECP was translated into Norwegian following a 6-step process: forward translation, forward translation synthesis, backward translation, backward translation synthesis, cognitive debriefing, and psychometric testing. The validity and reliability of the translated version were assessed using confirmatory factor analysis (CFA), Cronbach α, McDonald ω, and composite reliability.

A total of 399 nursing students completed the Norwegian version of the SECP. The CFA goodness-of-fit indices (χ2/df ratio=1.578, comparative fit index=0.98, Tucker-Lewis index=0.98, standardized root mean square residual=0.056, root mean square error of approximation=0.038) indicated an acceptable model fit. Reliability measures, including Cronbach ⍺, McDonald ω, and composite reliability, were high, with factor-level values ranging from 0.94 to 0.98.

The Norwegian version of the SECP demonstrated strong potential as an instrument for assessing self-efficacy in both current and required competencies among nursing students in clinical practice within nursing education. Future research should aim to confirm the factor structure of the SECP and evaluate its test-retest reliability.

This study aims to psychometrically validate the Psychache Scale (PAS) and investigate its prognostic value in predicting postoperative outcomes.

This is a prospective single-center study. Adults undergoing lumbar or thoracolumbar surgery were recruited. Participants completed PAS preoperatively and patient-reported outcome measures evaluating mental health, pain, physical function, and disability preoperatively and at one and six months postoperatively. PAS internal consistency was evaluated by Cronbach's alpha coefficient, and factor structure was evaluated using confirmatory factor analysis. Construct validity was assessed by examining correlations between PAS and measures of mental and physical health. PAS prognostic utility was evaluated by assessing its association with short- and longer-term surgical outcomes.

We included 166 patients. Mean (SD) age was 59.7 (12) years, with 55% females. PAS reliability was high (Cronbach's alpha = 0.95), and factor analysis confirmed the hypothesized one-factor structure. PAS showed strong correlations with PHQ-9 (r = 0.64), PROMIS anxiety (r = 0.64), pain catastrophizing scale (PCS) (r = 0.7), and its helplessness (r = 0.72), magnification (r = 0.59), and rumination (r = 0.59) subscales. However, it shows weak to moderate correlations with non-mental health-related metrics (0.07 < r < 0.44). Preoperative PAS was moderately correlated with one-month pain interference, and six-month PHQ-9 and PROMIS anxiety scores. In predicting outcomes, the addition of PAS to models including baseline values improved the prediction of all outcomes except for PROMIS physical function.

Our study suggests PAS may be a valuable tool for assessing psychological distress in this patient population. Further research is needed to understand its relevance in spine surgery practice.

The Eating Pathology Symptoms Inventory (EPSI) is a multidimensional self-report measure for the assessment of eating pathology and related aspects: Body Dissatisfaction, Binge Eating, Cognitive Restraint, Purging, Restricting, Excessive Exercise, Negative Attitudes Toward Obesity, and Muscle Building. The aims of the current studies were to provide a German translation of the EPSI and replicate the original EPSI's psychometric properties and correlates.

In two cross-sectional surveys using convenience samples (n = 361 and n = 178), participants completed the German EPSI along with other questionnaires.

In both studies, the EPSI's eight-factor structure, high internal consistencies, and differential associations with other instruments assessing eating disorder-specific and general psychopathology as well as gender differences on the EPSI's scales were largely replicated.

The German EPSI had sound psychometric properties that allow for a reliable and valid, multidimensional assessment of eating-disorder psychopathology.

To understand how laypeople define empathy, Hall, Schwartz, and Duong (2021) asked U.S. participants to rate how well items from various empathy measures matched their own definitions. The current paper (N = 549) is a replication of Hall, Schwartz, and Duong (2021, Study 2) using a highly similar study procedure, with a small extension consisting of items from an emotional contagion scale. We conducted a multi-group CFA to test the replicability of Hall et al.'s model, but the factor structure was not replicated. As an extension, we conducted an exploratory graph analysis (EGA), that revealed a similar factor structure, though some items were discarded due to poor fit. Additionally, the ranking of the items (i.e. what the participants saw as closest to their definition of empathy) shows the same pattern as in the original study. We consider this to be a successful partial replication of Hall et al.'s (2021) findings.

Social support is a protective factor for suicide and suicidal ideation (SI). However, inconsistencies exist regarding which aspects of social support are most protective for SI, potentially due to overlap amongst social support subscales. This study used bifactor modeling to test the cross-sectional and longitudinal relations between social support and SI, as bifactor modeling allows for the examination of subscale-specific relations after accounting for shared variance across all social support items (i.e., a general social support factor). Participants were 2445 adults on a waitlist for outpatient psychiatric treatment (M age = 37.74; SD = 14.75; 72.11% female) enrolled in a clinical trial assessing mobile app interventions. Participants completed a baseline measure of social support to assess appraisal support, belonging support, and tangible support, and an SI measure at baseline and 6-week follow-up. Confirmatory factor analysis compared correlated-factor and bifactor models of social support and examined associations with SI. A bifactor model of social support fit the data best. The general Social Support factor was negatively associated with SI at baseline and at 6-week follow-up. The specific social support factors explained minimal variation in SI after controlling for the general social support factor. Findings suggest that general social support, rather than lower-order dimensions, may be most relevant to assess when evaluating predictors of SI. Findings are consistent with theoretical accounts that suggest social support protects against escalating SI. Interventions targeting social support hold promise for ameliorating SI among individuals on waitlists for psychiatric treatment.

As evidence-based interventions are scaled, fidelity of implementation, and thus effectiveness, often wanes. Validated fidelity measures can improve researchers' ability to attribute outcomes to the intervention and help practitioners feel more confident in implementing the intervention as intended. We aim to provide a model for the validation of fidelity observation protocols to guide future research studying evidence-based interventions scaled-up under real-world conditions. We describe a process to build evidence of validity for items within the Session Review Form, an observational tool measuring fidelity to interactive drug prevention programs such as the Botvin LifeSkills Training program. Following Kane's (2006) assumptions framework requiring that validity evidence be built across four areas (scoring, generalizability, extrapolation, and decision), confirmatory factor analysis supported the hypothesized two-factor structure measuring quality of delivery (seven items assessing how well the material is implemented) and participant responsiveness (three items evaluating how well the intervention is received), and measurement invariance tests suggested the structure held across grade level and schools serving different student populations. These findings provide some evidence supporting the extrapolation assumption, though additional research is warranted since a more complete overall depiction of the validity argument is needed to evaluate fidelity measures.

To test the Self-Care Oral Anticancer Agents Index (SCOAAI)'s psychometric properties (structural validity, convergent validity, predictive validity, and internal consistency) in a sample of patients with solid tumour on Oral anticancer agents (OAA).

A methodological research in five in- or out-patient Italian facilities. Structural validity was tested by confirmatory factor analysis, and internal consistency was assessed through Cronbach's alpha and composite reliability. The Mann-Whitney U-test was used to test associations between SCOAAI scores and patient's emergency room admission, re-hospitalization, mortality, and quality of life measured three months after baseline.

We enrolled 356 patients; mostly were male (52.24%), and mean age was 59.10 years. Analyses demonstrated the SCOAAI's factorial validity and internal consistency. Moreover, patients that experienced emergency room admissions (U = 3484.5; P = .002) and re-hospitalization (U = 2446.0; P = .001) showed lower self-care maintenance scores; those who experienced emergency room admission (U = 3263.5; P = .019) and died at follow-up (U = 700.5; P = .025) had lower self-care monitoring scores; while patients that experienced re-hospitalisation (U = 2931.5; P = .040) and emergency room admission (U = 3285.0; P = .012) had lower self-care management scores. Patients with adequate self-care (≥ 70) reported significantly higher quality of life (self-care maintenance U = 1228.500, P < .001; self-care monitoring U = 3512.500, P < .001; self-care management U = 3287.500, P < .001).

According to our findings the SCOAAI is a valid and reliable tool. Patients with inadequate self-care can experience more emergency room accesses, re-hospitalization, death, and lower quality of life.

Adequate self-care behaviors can improve patient's outcomes and should be assessed by healthcare providers during the disease pathway.

Previous research investigating Internet gaming disorder (IGD) in China involved mainly youth samples despite the large population of adult gamers. Drawing on the self-regulatory executive function model, this study aimed to demonstrate the psychometric robustness of negative and positive gaming-specific metacognitions assessed by the short-form Metacognitions about Online Gaming Scale (MOGS; Study 1). Then, Study 2 aimed to explore bidirectional associations between these two factors of the MOGS and IGD among a broad age spectrum of Chinese adult gamers. Through online surveys, we obtained data from Chinese community adults: Study 1 surveyed 409 past-month gamers (Mage = 42.45, SD = 11.66; 53.8 % female) and Study 2 surveyed 266 past-month gamers (Mage = 34.76, SD = 11.78; 65.8 % female). Results of Study 1 supported the robustness of the two-factor structure, demonstrated the short-form MOGS' satisfactory convergent validity and reliability, and displayed its scalar invariance between community adults and university students. Study 2 found bidirectional associations between negative metacognitions only and IGD, in which baseline negative metacognitions were associated with higher levels of individuals' follow-up vulnerability to developing IGD. In contrast, IGD had a prospective effect on negative metacognitions 6 months later. IGD also showed a significant prospective effect on positive metacognitions. These findings demonstrate that the short-form MOGS is a cost-effective tool for measuring gaming-specific metacognitions in Chinese adults, highlighting the prominent role of negative metacognitions in the vicious circle of maladaptive metacognitions and IGD, which has implications for IGD preventions.

To evaluate the Danish patient-reported Impact of Event-Scale Revised (IES-R) as a screening tool for Acute Stress Disorder in a population of out-of-hospital cardiac arrest (OHCA) survivors.

The REVIVAL study was designed as a multicenter cohort study of OHCA survivors in which survivors self-reported the IES-R. A subset of survivors underwent the clinician-rated Acute Stress Disorder Interview during hospitalization. Psychometric evaluation of the IES-R included reliability and validity testing. Structural validity was assessed using factor analysis. The receiver operating characteristic curve and the area under the curve were used to evaluate the discriminative ability of different IES-R thresholds in classifying probable Acute Stress Disorder, as determined by interview. Sensitivity and specificity were calculated for each cut-off value. The best performing IES-R threshold was applied to the total population to examine prevalence of probable Acute Stress Disorder.

Overall, 244 survivors completed the IES-R, out of which 106 completed the Acute Stress Disorder Interview. Good internal consistency and convergent validity of the IES-R were observed. Factor analysis supported the original three-factor structure of the IES-R. An IES-R total cut-off score of ≥30 showed the best sensitivity-to-specificity ratio; the scale correctly classified 77% of the survivors with a sensitivity rate of 100% and a specificity rate of 75% (n = 106). Using this IES-R cut-off score, the prevalence of probable Acute Stress Disorder was 23% (n = 244).

The IES-R appears to be a useful screening tool for Acute Stress Disorder during hospitalisation and helps clinicians make post-cardiac arrest diagnostic and treatment decisions.

Given the insufficient validation of previously imported smartphone addiction scales in China, this study revised and evaluated the Problematic Smartphone Use Scale among Chinese college students (PSUS-C).

We based our research on a national sample comprising 1324 higher education institutions and 130 145 participants. Using cross-sectional data, comprehensive methods were employed to examine validity, reliability and measurement invariance.

The final scale consists of 20 items across four dimensions: withdrawal and loss of control, negative impact, salience behaviors and excessive use. All Heterotrait-Monotrait (HTMT) values were below 0.85, and the lower 90% and upper 95% confidence intervals were also below 0.85, except for factors 1 and 3. The amount of variance (AVE) values were greater than 0.5, composite reliability (ω) values exceeded 0.89 and all factor loadings were above 0.5. The criterion validity was supported as expected: problematic smartphone usage positively correlated with depression (r = 0.451), loneliness (8 items, r = 0.455), loneliness (6 items, r = 0.504), social media use (r = 0.614) and phone usage duration (r = 0.148); and negatively correlated with life satisfaction (r = -0.218) and self-esteem (r = -0.416). Across sex, type of university and place of residence, the measurement invariance performed well, with most changes in root mean square error of approximation (ΔRMSEA), comparative fit index (ΔCFI) and Tucker-Lewis index (ΔTLI) values being less than 0.005, and no indicator showing a difference greater than 0.010.

The Problematic Smartphone Use Scale for College Students (PSUS-C) demonstrated good factor structure, internal consistency, construct validity, discriminant validity and criterion validity. Strict and structural invariance were demonstrated across sex, type of university and place of residence. The PSUS-C has the potential to assess smartphone addiction among Chinese university students.

The current research aimed to provide initial psychometric validation of a new multifaceted mindfulness questionnaire (referred to as the State Four Facet Mindfulness Questionnaire, or the "state-4FMQ" for short) adapted from the commonly used Five Facet Mindfulness Questionnaire (referred to as the "trait-FFMQ"). The research was divided into two pre-registered studies. In both, undergraduates partook in a 20-minute mindfulness meditation (via audio recording), and then answered questions, including the state-4FMQ, pertaining to their experience during the meditation. In Study 2, participants additionally partook in a 20-minute control condition. The state-4FMQ was developed using exploratory factor analysis (EFA; Study 1) and confirmatory factor analysis (CFA; Study 2). In Study 2, a short-form of the state-4FMQ was established, and several additional forms of measurement validity were tested. EFA and CFA results supported a four-factor structure, which was identical to the trait-FFMQ with the exclusion of Nonreactivity. This newly created state-4FMQ, and its short-form, showed good internal consistency as well as convergent, predictive, and construct validity. In addition, it was found that some facets, more than others, predicted momentary well-being. The validity of the state-4FMQ shows that it can be used to measure multiple facets of state mindfulness across a variety of situations.

Despite the growing popularity of osteopathy in France, little is known about how French osteopaths conceptualise key aspects of their practice, including skills, knowledge, and decision-making. This study aimed to adapt and validate the Osteopaths' Therapeutic Approaches Questionnaire (Osteo-TAQ) for use in a French osteopathic population (Osteo-TAQfr) and to examine the professional profile and core elements of clinical practice among French osteopaths. The first objective was to establish the psychometric properties of the Osteo-TAQfr within a French osteopathic population. The second aim was to explore French osteopaths' conceptions of practice and their approach to patient care, thereby contributing to a broader understanding of the profession in France and its relevance within the discourse on allied health professions (AHPs).

A cross-sectional study was conducted to (1) adapt and validate the French version of the Osteopaths' Therapeutic Approaches Questionnaire (Osteo-TAQfr) and (2) explore osteopaths' conceptions of practice in France. The translation and cultural adaptation process was informed by cognitive interviews to ensure linguistic and contextual appropriateness. Exploratory Factor Analysis (EFA) was performed to assess the factor structure in the French osteopathic context and Confirmatory Factor Analysis (CFA) was used to test the validity of previously established constructs-Professional Artistry (PA) and Technical Rationality (TR). Internal consistency was evaluated using McDonald's omega (ω).

The survey yielded 1,703 complete responses. Analysis supported a two-factor model with PA andTR subscales, both showing strong reliability estimations (PA ω = 0.882; TR ω = 0.873). Minor theory-informed adjustments improved model fit. A moderate negative correlation was observed between the PA and TR subscales (r=-0.407). Respondents with additional health professions qualifications scored lower on the PA subscale and higher on the TR subscale.

The Osteo-TAQfr is an original tool that assesses conceptions of osteopathic practice in France. Findings reveal a predominance of TR among French osteopaths, characterised by biomedical, technique-driven approaches. These results have significant implications for aligning osteopathic education and practice with contemporary AHP paradigms, including patient-centred care and interdisciplinary collaboration. Further research should explore the transferability of the Osteo-TAQ across other healthcare systems and its potential impact on clinical outcomes and professional development.

Care Recipient Self-Perceived Burden (CR-SPB) to Caregivers is an important but overlooked aspect within the caregiver-care recipient relationship. This study aimed to (a) develop and validate the CARE-2B (Care Recipient's Two Burden) Scale, assessing both CR-SPB and their proxy assessment of caregiver burden (Proxy-CB); and (b) examine whether the CR-SPB and Proxy-CB differ from caregiver burden's own assessment and other health and social care constructs.

Data were collected from 504 caregiver-care recipient dyads in the United States using an online panel between August 2022 and February 2023. Care recipients completed the CARE-2B Scale, which includes two subscales: CR-SPB and Proxy-CB. Care recipients also completed measures related to health and well-being: SPB-scale, EQ-5D-5L, and EQ Health and Well-Being (EQ-HWB). Caregivers completed Care-Related Quality of Life (CarerQoL) and Adult Social Care Outcomes Toolkit for Carers (ASCOT-Carer). Psychometric analysis included exploratory and confirmatory factor analysis, item response theory (IRT), and construct validity.

CR-SPB correlated strongly with the SPB-scale (r = 0.73), whereas Proxy-CB correlated more strongly with caregiver-reported burden (r = 0.61). Both CR-SPB and Proxy-CB items demonstrated good discrimination and information coverage in IRT analysis. Exploratory factor analysis further supported the distinctiveness of CR-SPB and Proxy-CB, with CR-SPB items loading on a separate factor from caregiver burden and health constructs, whereas Proxy-CB aligned with caregiver-reported burden.

The CARE-2B Scale innovatively assesses both CR-SPB and Proxy-CB from the care recipient's perspective, providing new insights into the caregiving relationship. This dual-perspective measure has implications for enhancing care strategies for individuals with chronic conditions or disabilities and their caregivers.

An explanation for somatic complaints in adolescence assumes that they have the function to express emotional burden if the communication of feelings in important relationships does not work sufficiently. Therefore, it can be hypothesized that in adolescents, lower quality of emotional communication with a parent goes along with a higher impact of emotional burden on somatic complaints. The aim of this study was to examine whether emotional communication quality between adolescents and parents moderates the association of emotional burden and somatic complaints. Based on data from a cross-sectional population sample (N = 1061), structural equation modeling (SEM) was used to test the hypothesis. In addition to the general model, models for boys and girls were compared. Emotional communication quality does not moderate the association of emotional burden and somatic complaints in the general model or in the gender-based models. However, communication quality is a significant predictor of somatic complaints for boys. Limitations are the cross-sectional nature of the data, the possible sampling bias due to the use of an online access panel, and the inclusion of one parent per adolescent. This study highlights that emotional communication quality is a predictor for somatic complaints in adolescent boys and should be addressed in therapy.Trial registration ClinicalTrials.gov: NCT05332236.

To assess the psychometric properties of the simplified Chinese version of the Nonrestorative Sleep Scale (NRSS) in Chinese young adults and examine measurement invariance across language and age.

After cognitive debriefing, the simplified Chinese NRSS was administered to university students in mainland China in this cross-sectional survey (Study 1). The Pittsburgh Sleep Quality Index (PSQI), the Patient Health Questionnaire (PHQ-4), and sociodemographic characteristics were also self-reported. The sample was randomly split into two halves to examine the scale structure using exploratory factor analysis (EFA) and asses the psychometric properties of the identified structure by confirmatory factor analysis (CFA), respectively. Incorporating data from two additional studies (Study 2: a survey of Hong Kong Chinese adults; Study 3: a survey of mainland Chinese adolescents), multigroup CFA models were conducted to examine the measurement invariance across language and age, followed by a t-test to determine group differences once invariance was established.

In the 570 participants of Study 1 (28.8% male, age 20.2 ± 1.5 years), the EFA revealed a four-factor structure. The root mean square error of approximation, comparative fit index, and standardized root mean square residual in the CFA model were 0.053, 0.995, and 0.054, respectively. The statistically significant correlations of NRSS with PSQI (r = - 0.61) and PHQ-4 (r = - 0.53) demonstrated the convergent validity of NRSS. The internal consistency of the whole scale was 0.84. Measurement invariance was concluded between traditional and simplified Chinese NRSS and between young adults and adolescents with the change of comparative fit index and root mean square error of approximation smaller than 0.010. The effect size (Cohen's d) of difference between mainland Chinese adults and Hong Kong Chinese adults ranged from 0.193 to 0.771, while that between mainland Chinese adults and adolescents ranged from 0.027 to 0.345.

The simplified Chinese 12-item NRSS is valid and reliable for assessing NRS among Chinese young adults, and it can be used to measure and compare NRS between individuals using simplified Chinese and traditional Chinese, as well as across different age groups within the simplified Chinese user population.

The Problem Areas in Diabetes scale (PAID) is used to measure emotional distress levels related to diabetes mellitus (DM). However, consensus on its internal structure is lacking.

To compare the different internal structures of the PAID and propose a shortened version for Brazilian patients with diabetes.

Structural and criterion validity study.

We included Brazilian patients with type 1 DM (DM1) and type 2 DM (DM2) in this study. In accordance with the international consensus recommendations, we assessed the structural validity using confirmatory factor analysis (CFA) and used the following indices to evaluate model fit: root mean square error of approximation (RMSEA), comparative fit index (CFI), Tucker-Lewis index (TLI), standardized root mean square residual (SRMR), chi-square/degrees of freedom (DF), Akaike information criterion (AIC) and sample-size adjusted Bayesian information criterion (SABIC). Modification indices and factor loadings were used to reduce the number of items.

One hundred eighty-five patients, most of whom included women with DM2, participated in the study. The reduction in the PAID generated a unidimensional structure with 13 items (PAID-13). The PAID-13 presented the best-fit indices (chi-square/DF = 2.15, CFI = 0.989, TLI = 0.986, RMSEA = 0.079, and SRMR = 0.049). When the PAID versions with 13 and 20 items (original version) were correlated, a strong correlation was observed (rho = 0.941, P < 0.001).

The short version of the PAID scale with 13 items presented a more appropriate internal structure for Brazilian patients with diabetes.

Many universities have implemented bystander training programs to prevent relationship violence and sexual assault. Such programs encourage students to engage in behaviors to prevent interpersonal violence (i.e., bystander behaviors) if they witness situations that seem likely to escalate to violence. Bystander behaviors, however, often result in consequences, both positive and negative, for those who engage in them. Measures of consequences of bystander behaviors are starting to appear in the literature, but there is limited psychometric information for these measures. The current study examined psychometric properties of the General Outcomes of Bystander Actions Scale (GOBAS) by (a) attempting to replicate the original two-factor structure of the scale and (b) evaluating its criterion validity by examining its relation to future bystander behaviors. First-year undergraduate students (N = 730) were recruited into the study in 2016. Students completed the GOBAS at baseline. Students also completed a measure of bystander behaviors at baseline and at a 2-month follow-up assessment. Confirmatory factor analyses replicated the two-factor structure of the GOBAS only when items were scored dichotomously. Unexpectedly, after controlling for baseline bystander behaviors and other established correlates of bystander behaviors, negative consequences were related to more frequent bystander behaviors at the 2-month follow-up, while positive consequences were not. Findings support the two-factor structure of the GOBAS when items measure the occurrence of consequences. The findings, however, raise questions about the role of consequences in predicting future bystander behaviors.

The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), a questionnaire designed for the assessment of mental well-being, is widely used in different countries and cultures worldwide. However, there is a lack of studies examining its metric performance and measurement invariance across countries.

This study aims to examine the internal structure, reliability and cross-country validity of the WEMWBS in three European populations.

WEMWBS data collected in 2016 from three representative population health surveys from an autonomous region in Spain (Catalonia) and two countries (Denmark and the UK) were used (n=13 940). The mean WEMWBS Scores were compared between populations. The internal consistency (ω coefficients), internal structure (confirmatory factor analyses (CFA) and bifactor exploratory structural equation models), reliability (item response theory models, item and test information functions), and cross-cultural comparability (multigroup CFA) of the WEMWBS were assessed.

Differences in mean scores observed between regions merit further study. The WEMWBS showed high internal consistency across countries (ω=0.942). The unidimensionality of the scale was confirmed overall and for each population. Evidence of reliability and of measurement invariance at the configural, scalar and metric levels was found.

The results support the use of the WEMWBS in different cultures to inform the understanding of population well-being in public health and its possible use as an outcome measure in clinical studies.

The present study translated and evaluated the psychometric evidence of the Pandemic Grief Risk Factors (PGRF) in a sample of 363 people from the general population of Peru who suffered the death of a loved one by COVID-19 (63-4% women and 36.6% men, where 78.5% were between 18 and 29 years old). The findings indicated that the PGRF is a unidimensional and reliable measure. The PGRF items can differentiate between individuals with different levels of risk factors and thus cover a wide range of the latent construct. Also, a greater sense of distress for each of the risk factors for pandemic grief is necessary to answer the higher response categories. Risk factors significantly and positively predict COVID-19-associated dysfunctional grief. The results indicated that the PGRF in Spanish is a measure with adequate psychometric properties to measure risk factors for pandemic grief.

Early-life trauma (before age of 18 years) is hypothesized to increase the risk for adverse pregnancy outcomes through stress pathways, yet epidemiologic findings are mixed.

Sister Study participants (US women aged 35-74 years enrolled 2003-2009) completed an adapted Brief Betrayal Trauma Survey at the first follow-up visit. Lifetime history of gestational diabetes mellitus (GDM) or hypertensive disorders of pregnancy (HDP: pregnancy-related high blood pressure, pre-eclampsia/toxemia, or eclampsia) in pregnancies lasting ≥20 weeks was self-reported. We used log-binomial regression to estimate relative risks (RR) and 95% confidence intervals (CIs) for the association between early-life trauma (modeled using conventional measures [e.g., any experience, substantive domains, individual types] and latent classes of co-occurring traumas) and GDM or HDP among 34,879 parous women.

Approximately, 4% of participants reported GDM and 11% reported HDP. Relative to no early-life trauma, the RRs for any were 1.1 (95% CI = 1.0, 1.3) for GDM and 1.2 (95% CI = 1.2, 1.3) for HDP. Women reporting physical trauma had the highest risk of GDM and HDP in comparison to other substantive domains. In analyses using latent classes of early-life trauma, high trauma was associated with an elevated risk of both GDM (RR = 1.9, 95% CI = 1.5, 2.6) and HDP (RR = 1.7, 95% CI = 1.4, 2.0) compared with low trauma.

Women experiencing high levels of trauma in early life were at higher risk of GDM and HDP, adding to a growing evidence base for this association.

This study aimed to validate and assess the psychometric properties of the Chinese adaptation of the Strength-Based Parenting Questionnaire (SBPQ) for the first time. A sample of 1590 middle school students participated in this investigation. Both exploratory factor analysis and confirmatory factor analysis revealed that a 13-item two-factor structure (Strength-Based Parenting Knowledge, SBP-K, and Strength-Based Parenting Use, SBP-U) fit the data well (χ2/df = 8.138, RMSEA = 0.076, CFI = 0.962, TLI = 0.953, SRMR = 0.037), consistent with the original two-factor model. Moreover, internal consistency and test-retest reliability for the total scale and two subscales were found to be within the adequate range. Furthermore, the scores of the SBPQ, SBPQ-K, and SBPQ-U showed significant positive correlations with strengths knowledge scale (SKS), strengths use scale (SUS), and parental autonomy support/parental emotional warmth subscale in s-EMBU-C (Short-Egna Minnenav Barndoms Uppfostran-Chinese), while displaying significant negative correlations with parental protection subscale. The results of the cross-group measurement invariance models revealed that the SBPQ met configural invariance, metric invariance, scalar invariance, and residual invariance in participants of different genders, family structures, and family locations. Notably, scores among males were significantly higher than those of females, and two-parent children had higher scores than single-parent and other children. The scores of urban, township, and rural children decreased successively, with rural students scoring significantly lower than their counterparts did. In conclusion, the modified Chinese version of the Strength-based Parenting Questionnaire (SBPQ) appears to be a valid and reliable measure that is appropriate for widespread use among Chinese adolescent populations.

Muscularity bias internalization (MBI) refers to one's beliefs in negative muscularity-based stereotypes and negative self-evaluations due to muscularity. Empirical research shows that MBI significantly correlates with muscularity-oriented eating and body image disturbances. The Muscularity Bias Internalization Scale (MBIS) measures MBI and has been validated in general adult populations. Given that evidence supports a higher risk of eating and body image disturbances in Transgender and Gender-Diverse (TGD) people compared to their cisgender counterparts, validating the MBIS in TGD people is essential to further clarifying disparities in eating and body image disturbances in this population. With a sample of 410 Chinese TGD adults, exploratory and confirmatory factor analyses supported a two-factor structure. Comparisons of the second-order and bifactor models favored the second-order model. The MBIS showed good internal consistency and sound construct validity. Strong measurement invariance was confirmed across transgender men, transgender women, and gender-diverse groups, suggesting that these groups interpreted the MBIS similarly and that conclusions of differences in MBI across TGD adults can be considered true group differences. Specifically, transgender men reported the highest MBIS scores, followed by gender-diverse individuals, and then transgender women. These findings suggested that the MBIS appears to be a psychometrically sound instrument of MBI in Chinese TGD adults.
