Believing or “credition” refers to psychological processes that integrate the cognitions and emotions that influence our behavior. In the credition model by Angel and Seitz, four parameters are postulated: proposition, certainty, emotion and mightiness. It is assumed that believing processes are influenced by both the individual as well as socio-cultural factors and external circumstances. External or environmental circumstances can include threatening situations such as the ongoing pandemic. It has been hypothesized that believing processes related to the pandemic differ between individuals with bipolar disorder (BD) and healthy controls (HC).
To investigate credition in individuals with BD during the coronavirus disease 2019 (COVID-19) pandemic.
Psychiatrically stable individuals with BD (n = 52) and age- and sex matched HC (n = 52) participated in an online survey during the first lockdown of the COVID-19 pandemic. The survey took place between April 9th and June 4th, 2020, in Austria. Participants completed the Brief Symptom Inventory-18, the Beck Depression Inventory-II, the Altman Self-Rating Mania Scale, the Pittsburgh Sleep Quality Index and a dedicated Believing Questionnaire assessing four parameters of credition (proposition, certainty, emotion and mightiness). The MAXQDA software was used to analyze the qualitative data. Statistical analyses included analyses of variance, a multivariate analysis of variance and a multivariate analysis of co-variance.
Individuals with BD reported significantly more negative propositions [F (1,102) = 8.89, P = 0.004, η2p = 0.08] and negative emotions [Welch´s F (1,82.46) = 18.23, P < 0.001, η2p = 0.18], while HC showed significantly more positive propositions [F (1,102) = 7.78, P = 0.006, η2p = 0.07] and emotions [F (1,102) = 14.31, P < 0.001, η2p = 0.12]. In addition, individuals with BD showed a higher incongruence between their propositions and their emotions [F (1,102) = 9.42, P = 0.003, η2p = 0.08] and showed strong correlations between the parameters of the Believing Questionnaire and their psychiatric symptoms (r = 0.51-0.77, all P < 0.001). Positive as well as negative emotions and propositions were associated with scores measuring symptoms of depression, anxiety and sleep quality.
Believing parameters were associated with psychiatric symptoms in BD during the pandemic. Findings broaden knowledge about the susceptibility of believing processes for ambient challenges in individuals with BD.
Core Tip: Research concerning believing processes (“creditions”) in individuals with bipolar disorder (BD) during the coronavirus disease 2019 pandemic showed that patients reported more negative emotions and propositions than healthy controls who reported more positive emotions and propositions. Individuals with BD had a higher incongruence between their propositions and their emotions and strong correlations between the parameters of the Believing Questionnaire and psychiatric symptoms. These findings provide insight into the attitudes and beliefs of people with BD during a crisis.

Believing is a fundamental cognitive process involving belief formation, updating and evaluation[1,2]. Importantly, beliefs determine an individual’s behavior by allowing predictions of future events[3]. In the past century, believing has widely been neglected as an object of scientific interest since it was associated with spirituality or considered as abnormal[4]. Recently, however, there is growing interest in the processes of believing and beliefs in evolutionary biology, cognitive neuroscience, psychology and psychiatry[5]. This is corroborated by neuroimaging evidence revealing underlying neural correlates of believing[6-10]. To contextualize this research within the realm of cognition and emotion, the term “credition” is derived from the Latin word “credere” (which means “to believe”). This term highlights psychodynamic activities which underpin the believing processes resulting in stable but still modifiable states of belief[4].
Creditions are understood as dynamic processes that can activate at any time and influence existing states of belief which were constructed by a person's prior experiences[4]. Accordingly, creditions are an important part of our lives as they influence our thinking, feeling and acting and vice versa[11]. Sacks and Hirsch[12] postulated that people tend to accept something as reality until they are proven wrong and that belief formation can be understood as the result of perceptual and affective information processing. Supporting this notion, prior work demonstrates that integration of cognition and emotion occurs in the lateral prefrontal cortex[13]. In the credition model, four characteristic parameters are differentiated: proposition, certainty, emotion and mightiness[1]. “Proposition” represents the content of the statement. “Certainty” reflects the person's inclination to believe the proposition. “Emotion” reflects the affective valence of the proposition for a person. “Mightiness” reflects the degree of relevance of the proposition. It is assumed that believing processes are influenced by the individual themself as well as by socio-cultural factors and external circumstances[14]. Such external or environmental circumstances can include threatening situations including the ongoing pandemic.
The coronavirus disease 2019 (COVID-19) pandemic has deeply influenced the lives of the global population. Caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), it was labelled as a pandemic by the WHO on March 11th, 2020[15]. Since its outbreak, the virus has infected over 274 million and claimed the lives of more than five million people (December 2021)[16]. To contain the virus spread, several periods of lockdown have been implemented across the world contributing to far-reaching effects of the pandemic on the environment[17], economy, social life[18] and mental health[19]. The psychological consequences have been numerous[20], particularly for individuals with pre-existing psychiatric disorders including affective disorders[21].
Bipolar disorder (BD) is a neuropsychiatric affective disorder characterized by severe changes in mood ranging from depression to mania. Typically emerging in early adulthood, bipolar spectrum disorders have a prevalence of 1% to 6%[22,23]. Stressful events and exposure to life stress increase the recurrence of affective episodes in BD[24], making individuals with BD a vulnerable group during the COVID-19 pandemic[25]. Increased depressive symptoms, fatigue[26], psychological distress[27,28], post-traumatic stress symptoms[29], fear and sleeping problems[29,30] have all been shown in this population during this period. An increase in subjective cognitive dysfunction has also been found in this population and was associated with negative symptoms and poor quality of life[31].
In Beck’s cognitive model of depression[32], dysfunctional cognitive schemata are assumed to be the basis for the development of a depressive episode. This leads to a cognitive bias in information processing as attention is selectively directed towards negative aspects and experiences while positive events and memories are blocked[32,33]. Regarding the COVID-19 pandemic, the specific believing processes possibly contributing to the development of a depressive episode remain largely unknown.
The aims of the current study were: (1) To analyze believing processes, in particular the four parameters of proposition, certainty, emotion and mightiness in individuals with BD during the COVID-19 pandemic compared with healthy controls (HC); and (2) to investigate correlations between these parameters and psychiatric symptoms in BD.
Due to the still lacking empirical evidence in this field, this study utilized an exploratory approach. However, based on the literature, it was expected that in accordance with Beck's cognitive theory of depression[32], individuals with BD would show more negative propositions and emotions in their verbalized believing processes than HC. Further, it was expected that HC would show more positive propositions and emotions in their verbalized believing processes compared to individuals with BD. Additionally, it was hypothesized that current psychiatric symptoms would be related to possible differences in parameters between the two groups.
In total, 260 individuals were recruited; 208 of these had complete data sets. After matching for sex and age, the final sample was comprised of 52 stable, medicated individuals diagnosed with BD (29 males and 23 females) and 52 HC. The individuals with BD were previously diagnosed at the outpatient center for BD at the Medical University of Graz, Department of Psychiatry and Psychotherapeutic Medicine, using the Structured Clinical Interview for DSM-IV[34]. Exclusion criteria for HC were any psychiatric diagnosis, taking psychiatric medication or first-degree relatives with psychiatric disorders. Inclusion criteria for all participants were voluntary participation and e-mail access. All participants with BD and the majority of HC were recruited from the pool of the ongoing BIPLONG study which assesses lifestyle, metabolism and cognitive function in individuals with BD compared to HC. Additional HC were recruited by word of mouth and social media.
An online survey was sent out via the survey tool LimeSurvey (Version 3.27.4, Limesurvey GmbH) between April 9th and June 4th, 2020, starting 3 wk after the beginning of the first lockdown in Austria. Participants were thus experiencing travel restrictions, social distancing measures, and the closure of institutions such as schools, leisure venues and nonessential shops while completing measures for this study.
Participants gave informed consent before pseudo-anonymously responding to questionnaires. This study was approved by the local ethics committee in accordance with the current revision of the Declaration of Helsinki, ICH guideline for Good Clinical Practice and current regulations (Medical University of Graz, Austria; individuals with BD were from the BIPLONG study, EK-number: 25-335 ex 12/13; data was collected in the course of a new study, EK number: 32-363 ex 19/20).
Analyses in the current study were conducted on the following psychological inventories:
The Brief Symptom Inventory-18 (BSI-18) was constructed by Derogatis and Fitzpatrick[35], a short version of the Symptom-Checklist-90-Revised (SCL-90-R) by Derogatis and Savitz[36]. The BSI-18 was used to measure psychological symptoms during the last week. This measure yields a Global Severity Index (GSI) and three subscales: anxiety, depression and somatization, each with acceptable internal consistency (Cronbach’s alpha: GSI α = 0.93, anxiety α = 0.84, depression α = 0.87, and somatization α = 0.82).
The Beck Depression Inventory (BDI-II) by Beck et al[37] assessed the severity of depressive symptoms within the last week with a score of 18 or higher indicating clinically relevant depression. Assessed quality criteria were Cronbach’s alpha (α ≥ 0.84) and reliability (r ≥ 0.75)[38].
The Altman Self-Rating Mania Scale (ASRM) is a 5-item questionnaire that determines the extent of manic symptoms in the course of 1 wk[39]. Assessing self-confidence, mood, speech, activity level and need to sleep, each item is rated on a five-point scale (0-4). A score of five or more is considered clinically relevant.
The Pittsburgh Sleep Quality Index (PSQI) was constructed by Buysse et al[40] and measures sleep quality in the last month. The 19 items constitute seven components: subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep disturbances, use of sleep medication and daytime sleepiness. The sum score has a range of 0-21, with a higher score indicating worse sleep quality. A total score > 5 has diagnostic sensitivity of 89.6% and specificity of 86.5% (κ = 0.75, P < 0.001) when differentiating between poor and good sleepers.
The Believing Questionnaire (BQ) was created by JWS and ND of the Department of Psychiatry and Psychotherapeutic Medicine in consultation with HFA and RS. The BQ assessed the characteristic credition parameters (proposition, certainty, emotion, mightiness) during the COVID-19 pandemic. Consisting of six open-ended questions, the BQ was developed to gain insight in believing processes during such a precarious and challenging situation:
When I think of the current, very special situation, I believe;
When I think of my body, I believe;
When I think of my mental/emotional situation, I believe;
When I think of the coronavirus, I believe;
When I think of what the future holds 3 mo from now, I believe;
When I think of what the future holds 6 mo from now, I believe.
Participants were asked to answer as spontaneously and honestly as possible. Each question was then rated on a scale from 0 (= not sure) to 100 (= very sure) regarding the certainty of belief. Additionally, participants were asked to identify the emotion that arose for them in the context of that belief using an “Emotion Wheel” consisting of three concentric circles. The innermost circle showed the six basic emotions according to Ekman[41]: fear, anger, joy, sadness, disgust and surprise. The surrounding two circles provided options to further differentiate the basic emotion. The intensity of the emotion (sense of mightiness) was rated on a scale from 0 (= not sure) to 100 (= very sure) as well.
To analyze the qualitative data of the BQ in a standardized and transparent manner, MAXQDA 2020[42] software was used; this has previously proven useful in research of BD in clinical settings[43,44]. The process of analysis consisted of two independent raters categorizing individuals’ propositions and emotions into the three categories positive, negative and indifferent, generating six codes (positive propositions, negative propositions, indifferent propositions, positive emotions, negative emotions and indifferent emotions). The interrater reliability of κ = 0.92 was satisfactory.
To make data suitable for analysis with the Statistical Package for Social Sciences (SPSS version 26, IBM), six new variables were calculated to reflect the frequency of each code. Additionally, a variable reflecting the frequency of incongruencies between the valence of a person’s proposition and the identified emotion was created.
A multivariate analysis of variance (MANOVA) with group (BD vs HC) as the independent variable was calculated to test for between-subject differences in the credition parameters. Positive propositions, negative propositions and positive emotions were included in the MANOVA as variables because they were moderately intercorrelated (r = 0.64-0.78, all P < 0.001). Not all credition parameters were intercorrelated; as such, single ANOVAs were utilized for indifferent propositions, negative emotions, indifferent emotions, incongruence, certainty and mightiness. A multivariate analysis of co-variance with the same design but controlling for psychiatric symptomatology was then conducted. The psychiatric symptomatology consisted of the individual total scores in the BSI-18 (GSI), BDI-II and PSQI. The total score of the ASRM was not included because the two groups did not differ in their manic symptomatology. Spearman correlation analyses were used to test for associations between credition parameters and psychological test scores (BSI-18, BDI-II, ASRM and PSQI). Bonferroni correction (P < 0.003) was used to correct for conducting multiple tests. To test for normal distribution for the psychological test scores and credition parameters of both groups, Shapiro-Wilk tests were run and skewness and kurtosis were calculated. All data met the assumed criteria of linearity. The criterion of normality was not met for several variables (sex, negative propositions, positive emotions, negative emotions, indifferent emotions, and certainty) however, the sample size was adequate (n ≥ 30) and thus, normal distribution could be assumed, according to the central limit theorem. The criterion of variance was also not met for several variables (GSI, BDI-II, PSQI, negative propositions, positive emotions, negative emotions). However, the analyses were continued given that MANOVAs are relatively robust to violations of equality of variance[45] and for ANOVAs the Welch-ANOVA could be interpreted[46,47].
In addition, word clouds in MAXQDA were used to present propositions and emotions for each item of the BQ. Word clouds are a useful method to simultaneously visualize the actual words as well as their frequency[48]. The word clouds show the most frequently used words for each BQ item. Prepositions and conjunctions were ignored and added to a stop list in MAXQDA. The word clouds were translated from German into English for the present paper. It is noted that a loss of information may occur due to translation.
Each group consisted of 29 males and 23 females. Mean age was 50.2 years (individuals with BD; SD = 14.5) and 49.0 years (HC; SD = 13.3). The individuals with BD showed higher scores of psychiatric symptoms than the HC group [F (3,100) = 11.53, P < 0.001, Roy's Largest Root = 0.346, η2p = 0.257; see Table 1 for statistics].

The MANOVA testing for group differences in the believing parameters showed significant differences for the combined dependent variables of positive propositions, negative propositions and positive emotions [F (3,100) = 4.93, P = 0.003, η2p = 0.13, Roy´s Largest Root = 0.15]. Specifically, the HC group showed more positive propositions and emotions in their verbal believing processes than the individuals with BD. In contrast, the individuals with BD revealed more negative propositions and emotions compared with HC (Table 1). The individuals with BD showed a stronger incongruence between the valence of their propositions and the valence of their emotions. Furthermore, HC were more certain about their propositions than were individuals with BD. However, this difference did not remain significant after Bonferroni correction. No statistically significant differences emerged between the two groups in indifferent propositions and emotions or in mightiness.
After controlling for psychiatric symptoms (GSI score of the BSI-18, total scores of BDI-II and PSQI), the group differences in credition parameters were no longer significant.
Figures 1-3 show word clouds for the six BQ items. Results of item 2 (“When I think about my body, I believe”) and item 3 (“When I think about my mental/emotional situation, I believe”) are presented in more detail because there were significant differences between the two groups for both the valence of propositions [item 2: χ2(2) = 12.45, P = 0.002, Cramér’s V = 0.22 item 3: χ2(2) = 8.03, = 0.018, Cramér’s V = 0.27] and the valence of emotions [item 2: χ2(2) = 10.44, P = 0.004, Cramér’s V = 0.31; item 3: χ2(2) = 9.61, P = 0.005, Cramér’s V = 0.30]. For item 2, individuals with BD used a total of 352 words and the HC 273 words. For item 3, individuals with BD used a total of 486 words and the HC 292 words. The word frequencies of the different words for the two items are shown in Tables 2 and 3.

For item 2 (Figure 2, Table 2), both groups used the word “I” most often, followed by positive emotional words. The HC predominantly used positive words about their body, such as “fit”, “fitter” and “healthy”. In contrast, the individuals with BD, predominantly used the word “fat” for their body. In addition, the individuals with BD often used negative emotion words such as “fearful” and “unhappy”. For item 3 (Figure 2, Table 3), both groups again used the word “I” most frequently. However, the individuals with BD more frequently utilized self-centered words, such as “me” and “myself”, followed by positive emotion words, such as “good” and “content”. The HC used positive emotion words most often, such as “content”, “good”, “balanced” and “calm”.
For item 4 (“When I think of the coronavirus, I believe") and item 6 (“When I think of what the future holds 6 mo from now, I believe"), it was notable that individuals with BD used the word “I” and the HC the word “We” most frequently (see Figures 1 and 3).
Spearman correlation analyses between the believing parameters and psychiatric symptoms showed significant correlations in individuals with BD (P < 0.001 after Bonferroni correction; Table 4) for both positive as well as negative propositions and psychiatric symptoms. Specifically, there were significant negative correlations between the positive propositions and emotions and the BSI-18 scales GSI, depression and anxiety, the BDI-II and the PSQI sum score. Positive correlations were found between the negative emotions and the BSI-18 scales GSI, depression and anxiety, the BDI-II and the PSQI sum score. Additionally, a negative correlation was found between negative propositions and depression while GSI, the BDI-II and the PSQI sum score were positively correlated. No correlations were found with the scores in the ASRM.

In HC, there was only one negative correlation between certainty about the proposition and the BSI-18 GSI score (r = -0.48, P < 0.001, after Bonferroni correction).
Spearman correlation analyses were used to examine the extent to which the believing parameters depend on each other (Tables 5 and 6). The analyses were calculated for both groups separately. After Bonferroni correction, both groups showed significant correlations between propositions and emotions with a positive and negative valence. There was another significant correlation between certainty and mightiness. Furthermore, the controls showed significant correlations between the positive and negative propositions and incongruence.

In this study, creditions of individuals with BD were investigated using questionnaires tapping into beliefs and believing processes during the first wave of the COVID-19 pandemic. Findings showed that individuals with BD differed from controls in the believing parameters of propositions and emotions. Results confirmed our hypothesis that individuals with BD would show more negative propositions and emotions in their verbalized believing processes than HC. This corresponds to Beck's cognitive theory about negative dysfunctional cognitive schemata in depressive disorders[32]. Accordingly, a cognitive bias in information processing renders depressive individuals likelier to focus their attention more on negative aspects of life and to block positive aspects. This change in perception can result in negative believing processes. In addition, we found that individuals with BD showed greater incongruence between the valence of their propositions and the valence of their emotions compared to HC. Carl Rogers[49] has suggested incongruence as the root cause for the development of mental disorders. According to this concept, the actual experience does not match one´s own self-image. Recently, it was proposed that incongruence stems from a mismatch between the internal and external experiences and a person's self-concept, resulting in a state of tension[50]. The high incongruence we found in individuals with BD could therefore reflect an experiential incongruence within the individuals with BD themselves.
Furthermore, we observed that believing parameters were strongly related to psychiatric symptoms in the bipolar group. The correlations were particularly strong between the propositions or emotions and the total scores in the BSI-18, BDI-II and PSQI. The believing parameters related to propositions and emotions were more negative as psychiatric symptoms were more severe and more positive as psychiatric symptoms were less severe. In contrast, only a moderate negative association between GSI and the believing parameter of certainty was observed. One possible explanation for the fact that psychiatric symptoms and believing parameters were highly correlated in individuals with BD could be that individuals with BD generally experienced more psychiatric symptoms during the COVID-19 pandemic. Another possible explanation is that individuals with BD ruminate more on emotional experiences, both negative and positive[51-53]. Consequently, cognitions and emotions appear to have a profound impact on mental health in individuals with BD.
An interesting result of this study was that after controlling for psychiatric symptoms, i.e. total scores in BSI-18, BDI-II and PSQI, the differences in believing parameters between the two groups disappeared. This finding suggests that believing processes reflect important aspects of life that are also represented by the questionnaire for psychological symptoms. This could be explained by an intrinsic modulator function that is accounted for by the credition model[1]. On the molecular level, the modulator function may be linked to the dopamine system which plays an important role in believing processes[54,55] as well as for abnormal believing processes in psychiatric disorders[56-58].
The word clouds we created showed that the individuals with BD used words of emotion with negative connotations more often compared to the control group. Moreover, those with BD used more self-centered language than HC. We, therefore, assume that individuals with BD tend to consider the self in the focus of their believing processes more often than the HC. Interestingly, individuals with BD more frequently answered the two items “When I think of the coronavirus, I believe” and “When I think of what the future holds 6 mo from now, I believe” from an individual perspective using the word “I”, whereas HC more often answered from a group perspective with “We”. Perhaps individuals with BD depend more upon the self in the context of coping while healthy individuals are more likely to refer to social reasoning. Another explanation for this finding is that individuals with BD could be the disorder itself and the associated introspection processes and self-awareness, possibly learned in psychotherapy, as all patients were treated at the outpatient center for BD at the Medical University of Graz.
The present study had several limitations. Due to the lockdown in Austria at the time of study, testing was limited to online questionnaires precluding face-to-face interactions with study participants. Nevertheless, scores from self-report did allow us to capture and control for current symptoms. Another potential problem of this, as well as other online studies, is that of sampling bias. Only data from individuals who were motivated to participate in the survey were collected. Thus, results may not apply to the general population. Furthermore, believing processes themselves could not be studied, as only the verbalized expressions could be directly assessed. It may be inferred that believing processes were influenced by the introspective ability of the subjects; however, introspective ability was not measured in the present study. A further limitation of the current study is that the qualitative data of the BQ had to be transformed into positive, negative and indifferent categories, that is, the data were reduced profoundly and may thus miss some important information. Lastly, as this was a cross-sectional study, causality cannot be determined.
Our findings offer practical implications for the treatment of individuals with BD. Because differences in believing parameters were no longer present after controlling for psychiatric symptoms, the credition model could contribute to a better understanding of negative or even positive dysfunctional schemata in psychiatric individuals, as well as be adopted into the psychotherapeutic context. Since humans tend to believe their perceptions to be true and beliefs can be updated by confirming or disproving new evidence[57], dysfunctional cognitive schemata could presumably be changed if they were revealed. It is hypothesized that belief evaluation is one approach to help with this and could be used as a tool for cognitive treatment approaches in psychotherapy.
The present study showed that the model of credition is applicable in the clinical context regarding the postulated believing processes. Individuals with BD differed in their believing processes regarding the COVID-19 pandemic from healthy persons. Thus, this study provides a deep insight into the attitudes and beliefs of particularly vulnerable people during a global crisis. Believing parameters should be examined in other clinical groups in future studies.
Believing, or “credition,” refers to psychological processes that integrate the cognitions and emotions influencing our behavior. Angel and Seitz created a model consisting of four credition parameters: proposition, certainty, emotion and mightiness. Believing processes are postulated to be influenced by external or environmental circumstances, such as the coronavirus disease 2019 (COVID-19) pandemic.
As empirical evidence about believing processes is lacking, studies examining this field of research are needed. Investigating credition during a crisis, such as the COVID-19 pandemic, will hopefully provide valuable insight into the mind of individuals with bipolar disorder (BD) and might be able to offer implications for treatment.
The purpose of this study was to explore credition in individuals with BD as well as healthy controls (HC) during the COVID-19 pandemic.
Euthymic individuals with BD (n = 52) and age- and sex matched HC (n = 52) from Austria participated in an online survey taking place from April 9th to June 4th, 2020. The following questionnaires were completed: Brief Symptom Inventory-18, Beck Depression Inventory-II, Altman Self-Rating Mania Scale, Pittsburgh Sleep Quality Index and a Believing Questionnaire assessing four parameters of credition (proposition, certainty, emotion and mightiness). The MAXQDA software was used to analyze data about believing processes. Statistical analyses included analyses of variance, a multivariate analysis of variance and a multivariate analysis of co-variance.
Individuals with BD showed significantly more negative propositions and negative emotions, whereas HC reported significantly more positive propositions and emotions. Moreover, individuals with BD showed a higher incongruence between their propositions and emotions. Positive as well as negative emotions and propositions were associated with scores measuring symptoms of depression, anxiety and sleep quality.
During the COVID-19 pandemic, believing parameters were associated with psychiatric symptoms in BD and differed from HC. Results demonstrate the sensitivity of believing processes to external influences in individuals with BD.
Believing processes should be further examined in future studies, especially regarding cognitive treatment approaches in psychotherapy.
