To evaluate the effect of educational intervention on individuals’ knowledge of and attitudes toward forensic mental health.
We conducted a questionnaire regarding attitudes toward various ideas about forensic mental health. The respondents attended a 1-h seminar regarding forensic mental health after answering the questionnaire. On completion of the seminar, the respondents answered another questionnaire containing many of the same questions as contained in the pre-seminar questionnaire.
A total of 86 individuals attended the seminar, and 78 responded to the questionnaire. Only 13 (18.8%) participants were supportive of the concept of criminal responsibility initially, and there was a statistically significant increase in those who became more supportive after the seminar, with 22 (33%) being supportive after the seminar (Wilcoxon signed-rank test, P < 0.001). Logistic regression analysis revealed that participants who were skeptical about forensic mental systems and those with fewer opportunities to see media reports regarding psychiatry were likely to become supportive of criminal responsibility after the intervention.
These results suggest that public attitudes toward criminal responsibility and mental health can be influenced via educational interventions.
Core tip: Many people have an unsympathetic attitude against offenders with mental disorders. However, this seems, to some extent, to be attributable to a lack of precise knowledge about forensic mental health. We prove that public opinion toward criminal responsibility and relevant ideas regarding forensic mental health can be amended via brief educational interventions. Access to accurate information can help to reduce discrimination against offenders with mental disorders.

Most legal systems and societies require that the criminal responsibility of the offender be proven before they are subject to sanctions. Thus, offenders who commit crimes when they are considered legally insane because of a mental disorder should not be punished. This concept is considered as rational in most developed countries for a number of reasons. First, people under the overwhelming influence of psychiatric symptoms cannot control their behavior. It is inappropriate to demand that they regulate their acts. Second, punishment is not effective to prevent recidivism for people who have committed a crime directly caused by psychiatric symptoms such as delusion. Third, the provision of immediate and appropriate psychiatric treatment, that is, diverting them from the criminal justice system to the mental health care system, is an effective way to reduce the risk of reoffending.
Despite recognition of the concept in various contexts internationally, many citizens have difficulty accepting or understanding criminal responsibility. When an individual with a confirmed or suspected mental disorder commits a sensational crime, a broad discussion is typically ignited regarding the criminal responsibility of the offender[1-4]. Consequently, many countries are struggling to establish their own forensic mental health systems to deal with mentally disordered offenders (MDOs), while also taking into consideration the unique cultural background of each country.
In the Japanese legislation, an act of insanity is not punishable, and that an act of diminished responsibility shall lead to the punishment being reduced, according to the article 39 of the Penal Code. Insanity is defined by the Supreme Court as a state without ability to recognize the difference between good and evil, and to control oneself due to mental disorders. Diminished responsibility is defined as a state with those abilities strongly impaired due to mental disorders.
For many years, Japan had no specific legal provision for MDOs. Therefore, MDOs were treated under the Mental Health and Welfare (MHW) Act. After some debate, the Act on Medical Care and Treatment for Persons Who Have Caused Serious Cases under the Condition of Insanity (abbreviated to the Medical Treatment and Supervision Act, or the MTS Act) came into force in 2005, coinciding with the widespread reform of the Japanese forensic mental health system. Under this new scheme, individuals committing a serious criminal offense while insane or having a diminished responsibility are dealt with within a judicial, administrative framework. The enactment of the MTS Act also meant that clinical psychiatrists would have an opportunity to collaborate with legal professionals such as judges and lawyers in the treatment of MDOs. Additionally, judges faced the necessity of learning about clinical psychiatry for appropriate decision making under the MTS Act.
On the other hand, for those offenders that are not identified as not guilty by reason of insanity (NGRI) nor as having diminished responsibility, they are treated the same as in the past. Therefore, the degree of criminal responsibility of each offender plays a crucial role in determining their treatment. It is for this reason that significant attention is paid to the criminal responsibility of offenders in Japan.
Previously, citizens in Japan had few opportunities to be involved in discussions regarding the criminal responsibility of offenders. However, this changed with the introduction of the Lay Judge Act in 2009. This act regulates the role of lay judges, who are selected from Japanese citizens for certain legal trials. For the first time, citizens had the opportunity to take a role in the criminal trials of MDOs. Furthermore, court judges and psychiatrists, as expert witnesses, were now required to explain the concept of criminal responsibility to lay judges using precise and easy-to-understand language.
Because of the above, an awareness of citizens’ levels of understanding of forensic mental health is now important. To date, there are very few reports regarding the attitudes of citizens toward the concept of criminal responsibility. A literature review from an earlier study, which was accompanied by a survey of psychiatric outpatients, only identified two unpublished online surveys on this issue. Furthermore, the validity of those surveys is questionable because of small sample sizes and biased sampling. That study suggested that more than 70% of participants were opposed to the concept of criminal responsibility, whereas psychiatric patients and their family members were generally supportive of the concept.
Based on this situation, we considered it essential to examine the degree of understanding of forensic mental health among citizens in Japan using an appropriate method. We especially wanted to determine the degree to which they respected the concept of criminal responsibility. We assumed that the majority of citizens, although they may be curious about forensic mental health, have negative attitudes regarding this concept. Existing evidence suggests that Japanese citizens hold a stronger stigma against patients with mental disorders than do Australians, and are more reluctant to mention mental disorders than are British citizens. His evidence points to the possibility that Japanese citizens have relatively negative attitudes toward MDOs.
We were also interested in whether individuals’ opinions and attitudes can be changed via an educational intervention. This idea is derived from the estimation that unsympathetic attitudes toward MDOs may originate from a lack of knowledge regarding forensic mental health. Japanese people have little opportunity to learn about the situation of MDOs unless they are directly involved. Meanwhile, the media tends to sensationally report a few extreme criminal acts committed by patients with mental disorders, and these extraordinary cases are often generalized in the mind of the public. Therefore, some people may incorrectly conclude that numerous MDOs are released out into the public without any follow-up after receiving an NGRI verdict. In reality, there are only a few NGRI verdicts annually. The situation is similar in the United States; an informal survey suggested that people have difficulty understanding the real situation regarding NGRI verdicts. Thus, they believed that 5%-20% of defendants were found NGRI, despite this rate being only 1% in reality.
Considering these facts, it is expected that after learning that NGRI verdicts are very rare and that such cases receive special forensic psychiatric treatment under the MTS Act, we believe citizens will become more supportive of the concept of criminal responsibility. A more supportive attitude by citizens toward MDOs will alleviate the emotional conflict around mental disorders, and will contribute to the realization of a society that is less discriminatory against people with mental disorders.
Based on the background descried above, we hypothesized that providing some specific knowledge about forensic mental health may change citizens’ attitudes regarding MDOs. We planned an educational seminar on the concept of criminal responsibility and NGRI, the current situation of forensic mental health, and how MDOs are treated in special facilities. We considered a 1-h lecture would be adequate to accomplish the outcome, referring to a previous study in which a 1-h session on psychiatry was effective in changing individuals’ attitudes toward mental disorders.
MATERIALS AND METHODS
To test the hypothesis mentioned above, we conducted a study that combined a series of questionnaires and a seminar. This study was a single-group, open-labeled interventional confirmatory trial. We presented a seminar on forensic mental health titled “What is forensic mental health: psychiatry, psychiatric testimony, mental disorders and crimes.” The seminar was held at the Inohana Festival, a college campus festival administered by the Graduate School of Medicine, Chiba University, on November 1 and 2, 2014. The seminar was open to all interested attendees. We asked the audience to answer a questionnaire before the seminar started. We then administered a further questionnaire after the seminar concluded. We compared the results of the two questionnaires (pre- and post-seminar) using statistical analysis.
The subjects of this study were the seminar attendees. Inohana Festival is a well-known campus festival within the local area. Thousands of people, mainly local residents, the families and relatives of college students and workers, and high school students who are interested in Chiba University, visit each year.
We recruited attendees through an advertisement of the seminar on the festival website and a poster explaining the theme of the seminar. Any people who came to Inohana Festival were permitted to attend the seminar. All of the individuals who attended the seminar and completed the pre-seminar questionnaire were included as participants in this study. There were no exclusion criteria regarding participation.
We designed an anonymous self-reporting questionnaire sheet to deliver to the seminar audience. On this sheet, we disclosed the title and funding information of the study. We guaranteed that those who refused to answer the questionnaire could still attend the seminar.
Seminar attendees were given the two questionnaires (pre-seminar and post-seminar) at the same time. The components of the pre-seminar questionnaire are shown in Table 1. This questionnaire was originally created for a previous study examining the attitudes of psychiatric patients toward forensic mental health. We decided to use a slightly modified version of this questionnaire because we expected to be able to compare the results of this study with those of the previous survey. In addition to the degree of knowledge about and attitudes toward forensic mental health, we also wanted to clarify the relationship between participants’ perceptions about forensic mental health and their degree of exposure to media reports. We sought to do so because reporting on criminal cases with MDOs is sometimes sensationalized. Furthermore, we were curious about the opinions of citizens toward the practice of anonymous reporting about MDOs in the media. Whether the name of a suspect should be concealed when the suspect seems to be an MDO is often discussed in Japan. Attitudes expressed in the media are mixed (Science Council in Japan, 2005), but patients with mental disorders and their families tend to approve of the practice of anonymous reporting.
MHW Act: Mental Health and Welfare Act; MTS Act: Medical Treatment and Supervision Act; OIH: Official Involuntary Hospitalization.
The questionnaire was composed of four sections: (1) knowledge about forensic mental health; (2) opinions regarding forensic mental health; (3) the relationship between psychiatry and the mass media; and (4) information about the responders. Several items were included in each section. Most of the items were ranked using a five-point scale. A serial number was attached to each pair (pre- and post-seminar) of answer sheets in advance to identify which two sheets were completed by the same participant.
We explained the purpose of the study to the audience and then asked them to complete the pre-seminar questionnaire. After completion, we collected the pre-seminar answer sheets before the seminar began. The participants retained the post-seminar answer sheets during the seminar. Those who refused to answer the questionnaire were deemed to have dropped out of the study, but they could still attend the seminar if they wished.
The seminar was 1 h in duration and comprised two lectures: “criminal responsibility” and “forensic psychiatric treatment.” For each seminar, a leading psychiatrist with a judgment physician license gave a presentation. In the first lecture, the lecturer explained how the concept of criminal responsibility was interpreted in Japanese legislation. Next, he explained the mechanisms through which mental disorders can be a cause of behaviors that harm others. An outline of the psychiatric evaluation of an MDO was then introduced. In the second lecture, another lecturer began by introducing the designated medical facility. He also presented the content of the treatment program provided in the facilities. Finally, data regarding the outcome of special treatment for MDOs were shared. After each lecture, the presenters answered questions from the participants.
After the seminar concluded, we asked the attendees to answer the post-seminar questionnaire. Sections 1-3 from the pre-seminar questionnaire were included in the post-seminar survey; section 4 was omitted. Upon completion, we collected the answer sheets.
This survey focused only on the opinions of individuals and did not deal with any patients. We gathered no personal information from the participants. The return of the questionnaires was deemed to indicate consent to participate in this anonymous survey. We registered this study with the Clinical Trials Registry of the University Hospital Medical Information Network (UMIN, Tokyo, Japan) with the unique trial number UMIN000015725.
We counted the questionnaire sheets returned to calculate the response rate. We then compiled the ratings for each item of the pre-seminar questionnaire. Furthermore, we examined the correlations between each item regarding knowledge and opinions (in sections 1, 2 and 3) and the demographic data collected on respondents (in section 4) using a chi-square test.
We also examined the change in participants’ opinions about forensic mental health. Using the serial numbers on the answer sheets, we identified which sheets were paired. In these comparisons, pairs missing either pre-seminar or post-seminar responses were excluded from the analysis. The pairs for each item were statistically analyzed using a two-tailed Wilcoxon signed-rank test.
We then applied a logistic regression analysis to our data to identify factors predicting the plasticity of opinions on criminal responsibility. To conduct this analysis, we categorized the participants into two groups: (1) those whose pre-seminar opinion on criminal responsibility became more supportive; and (2) those whose opinion did not change or who became less supportive. This binary variable was set as the dependent variable, and all other items answered in the pre-seminar questionnaire were set as independent variables. Cases with missing data on opinions toward criminal responsibility either pre- or post-seminar were excluded from this analysis. We applied a logistic regression analysis using the forward stepwise (Wald) method.
The collected data were analyzed using IBM SPSS Statistics for Windows, Version 22.0 (IBM Corp., Armonk, NY, United States). We set the level of significance at P < 0.05 before conducting the analyses.
Of the 86 people attending the seminar, 78 (91%) answered at least one item in the questionnaire, of which 69 people completed the both pre- and post- questionnaire. We included all 78 answers in the initial analysis. The number of valid answers in each item is described in each table.
The largest age group was those aged 50-59 years, with only four attendees aged over 60 years. Thirty-seven (47%) attendees were men, and 48 (62%) were neither medical practitioners nor medical students.
In the pre-seminar questionnaire, only half (n = 39) of the respondents stated they had previously heard the term “forensic psychiatry,” and 48 (62%) had no knowledge of the contents of the MHW Act. In contrast, 74 (95%) respondents had previously heard the term “criminal responsibility.” Furthermore, 53 (68%) respondents did not know about the introduction of the MTS Act, compared with 63 (81%) who were aware of the Lay Judge Act coming into force.
In the pre-seminar questionnaire, 37 (47%) and 35 (45%) respondents definitely agreed with the concept of official involuntary hospitalization (OIH) and the MTS Act, respectively. In contrast, only 13 (17%) had a positive attitude (“definitely agree” or “relatively agree”) toward the concept of criminal responsibility, and 37 (47%) were against it (“relatively disagree” or “definitely disagree”). Regarding the Lay Judge Act, 34 (43%) had a favorable opinion, whereas 17 (22%) had a negative one. The responses reflected varied opportunities for exposure to media reports on psychiatry, while 59 (76%) participants believed that the media should report more frequently on mental health issues. The majority (55%) of participants answered that they had seen more recent media reports regarding the relationship between psychiatry and crime than in the past, and 45 (58%) believed that the media should intensify the frequency of reports explaining this topic. Opinions regarding anonymous reporting about suspects with mental disorders were split. These results are presented in Table 2.

We compared the results of the answers between the pre- and post-seminar questionnaires in the pre- and post-pairs (n = 66). More respondents had a positive opinion regarding the concept of criminal responsibility after the seminar than before (Wilcoxon signed-rank test, Z = -3.6758, P < 0.001). In addition, respondents’ opinions toward OIH (Wilcoxon signed-rank test, Z = -2.017, P = 0.044) and the Lay Judge Act (Wilcoxon signed-rank test, Z = -2.467, P = 0.014) were also changed to be more favorable. No significant differences between pre- and post-seminar were detected for opinions toward the MTS Act (Wilcoxon signed-rank test, Z = -0.498, P = 0.619). Compared with pre-seminar attitudes, the post-seminar questionnaire answers showed that more respondents wanted to see more frequent media reports on the relationship between psychiatry and crimes (Wilcoxon signed-rank test, Z = -3.051, P = 0.02), and more respondents had a positive opinion concerning the anonymous reporting of suspects with mental disorders (Wilcoxon signed-rank test, Z = -2.185, P = 0.029). No significant changes were detected regarding the level of reporting on psychiatry (Table 3).
Table 3 Changes in opinions on psychiatry: Pre- and post-seminar.

The logistic regression analysis with the forward stepwise (Wald) method showed two independent variables as being associated with the positive change of opinion toward the concept of criminal responsibility: “opinion toward the MTS Act” [coefficient (B) = -0.540, odds ratio = 0.583, 95%CI: 0.341-0.997, P < 0.05] and “opportunity to see media reports regarding psychiatry” [coefficient (B) = -0.394, odds ratio = 0.674, 95%CI: 0.456-0.997, P < 0.05]. Thus, participants who were not supportive of the MTS Act before the seminar and those who had fewer opportunities to see media reports regarding psychiatry were more likely to become more supportive of criminal responsibility after attending the seminar.
In this study, we conducted a questionnaire survey regarding forensic mental health with two key aims. First, we identified participants’ level of awareness and opinions about the current situation of forensic mental health in Japan. Second, we examined the possibility of changing participants’ opinions via a 1-h educational intervention, based on our hypothesis that citizens’ opposition to the concept of criminal responsibility derives from a lack of knowledge on forensic mental health.
The participants of the present study were voluntary seminar attendees. Thus, it is likely that most were interested in or at least curious about psychiatry. Nevertheless, only half of the participants had previously heard the term “forensic psychiatry.” In addition, the majority of participants had no knowledge of either the MTS or MHW Act. These results show that the participants did not have even a superficial knowledge of forensic mental health. In contrast, most of the participants had previously heard the term “criminal responsibility.” This might be because the mass media sometimes reports cases in which criminal responsibility is questioned. However, the depth of the participants’ understanding about criminal responsibility was uncertain. It is possible that Japanese citizens’ knowledge about forensic mental health is very limited.
Very few studies similar to ours have been performed in Japan. Ando et al conducted a mail survey of 3000 citizens to investigate their knowledge regarding forensic systems. In that study, respondents had a good knowledge of psychiatric testimony, but the majority had little awareness of the MTS Act. These results are consistent with our findings.
In contrast, citizens’ recognition of the Lay Judge Act has been repeatedly investigated by both government and media organizations[17,18]. Previous studies suggest that over 90% of citizens are aware of the enactment of the Lay Judge Act. The percentage is higher than that found in the present study; however, it is highly likely that the Lay Judge Act is better known than the MTS and MHW Acts. This fact may reflect a lack of clarity among citizens about mental health in Japan.
In 2010, we conducted a survey of psychiatric outpatients using a questionnaire with content similar to the questionnaire used in the present study. In the 2010 survey, 86.7% of patients and 91.4% of their families had previously heard of the term “criminal responsibility.” We found a similar percentage in the present study. The participants in this study, as well as psychiatric outpatients and their families, can be considered to be more concerned about forensic mental health than are citizens in general. Therefore, we consider the degree of awareness of forensic mental health among the public to be lower than these results.
In this study, approximately 60% of respondents opposed the concept of criminal responsibility before the seminar. Considering the small sample size and convenience sampling method of this study, it is difficult to generalize this result. However, to date no other structured research evaluating the national opinion on this concept has been reported. A nationwide survey with non-biased samples is required to certify our result.
It is possible that more than a few citizens consider it unfair that patients with mental disorders are not deemed criminally responsible (partially influenced by media reports), although it is very rare that an insanity defense is successful in court. Indeed, some researchers insist on abolishing the concept of criminal responsibility because it is seen as a form of discrimination. However, in the post-seminar questionnaire, we saw a statistically significant increase in the number of respondents who were supportive of the concept of criminal responsibility, and these supporters became the majority group. Thus, a considerable proportion of the audience changed their opinions regarding criminal responsibility after attending the 1-h seminar.
In other words, some people originally opposed to the concept of criminal responsibility may have simply lacked a good understanding of mental disorders and forensic mental health systems. This hypothesis is consistent with the finding from the logistic regression analysis that participants with fewer opportunities to see media reports on psychiatry were more likely to become more positive toward the concept of criminal responsibility after the educational intervention.
It is noteworthy that participants who were unsupportive of the MTS Act tended to change their opinion, becoming more supportive of criminal responsibility. It is hypothesized that those who previously held a negative view of forensic psychiatric treatment changed their attitude after gaining knowledge on forensic mental health, resulting in a more positive attitude about the concept of criminal responsibility.
In contrast, the majority of respondents were supportive of OIH and the MTS Act before the seminar. After the seminar, the proportion of supporters increased; this increase was statistically significant for OIH but not for the MTS Act. These results suggest that a challenge remains regarding how to teach citizens about special treatment for MDOs. This seminar did not include case presentations of MDOs. Exposure to patients with mental disorders in a clinical setting is considered beneficial in reducing stigma against mental illnesses. However, it is technically and ethically difficult to organize a session in which citizens can interact with MDOs. A case presentation with a realistic atmosphere that enables audiences to imagine an MDO and their process of recovery is desirable to maximize the effect of seminars.
We found that after the seminar, more respondents were willing to be exposed to media reports regarding the relationship between psychiatry and crime. This increase was statistically significant and may indicate motivation on the part of the participants to learn about forensic mental health.
There is some debate as to whether the media should report criminal cases and name the alleged offender when he or she may suffer from a mental disorder. Traditionally, Japanese media have maintained anonymity in such cases. In this study, the number of respondents supporting this kind of anonymous reporting increased following the seminar. This suggests that a considerable number of participants considered the risks of naming alleged offenders suspected to suffer from a mental disorder.
Regarding study limitations, this study was a non-controlled trial. The participants, recruited through convenience sampling, may have already been motivated and interested in our lecture. Thus, it is unclear to what level the general population understands forensic psychiatry and how rigid their opinions against forensic mental health are. However, it seems unfeasible to force citizens who are indifferent to this issue to attend the seminar. Further studies should be conducted using larger and less biased samples to achieve more precise results. Additionally, randomized controlled trials are needed to evaluate the power of influencing the opinions of attendees with more precision. For example, an interventional trial in school settings with cluster sampling may contribute to confirming our hypotheses.
General discrimination against patients with mental disorders still exists in Japan. People in Japan have a stronger tendency to judge patients with schizophrenia as unfamiliar and risky to the community than people in the United Kingdom or the United States. These results indicate the necessity of education not only on forensic mental health but also regarding general psychiatry.
In conclusion, in Japan, the enactment of the MTS Act and the Lay Judge Act opened a door to a new age for forensic mental health. The MTS Act aims for the early reintegration of MDOs into the community, and the Lay Judge Act provides greater opportunities for citizens to be involved in criminal trials in Japan, many of which involve MDOs. However, the level of concern of citizens about forensic mental health still appears to be low. Even among participants attending our seminar about forensic mental health, many knew very little about the legislation concerning MDOs. Additionally, the present study shows that the majority of citizens seem unsupportive of the concept of criminal responsibility. However, the results demonstrated the possibility that an educational intervention can change the opinions of citizens regarding these issues. After providing the participants with proper information and knowledge, they became more supportive of the concept of criminal responsibility, admitting the necessity of proper treatment for MDOs with NGRI rather than harsh punishment. This result is consistent with our hypothesis that a lack of knowledge about forensic mental health is associated with unsympathetic attitudes toward MDOs. As mentioned above, however, there are several elements that should be examined to confirm our hypothesis. A national survey with larger and non-biased samples is required to fully clarify public opinion toward forensic mental health. Interventional studies should employ random sampling methods to identify the exact effect of such seminars. The longitudinal effect of the intervention also needs to be examined with a follow-up session. Controlled trials will be beneficial to specify which elements are essential to help attendees alter their opinions. In terms of research settings, schools can be advantageous because of the availability of homogeneous subjects and participants’ readiness to attend seminars. The content of these seminars should include case presentations.
There is scarce evidence regarding citizens’ attitude to forensic mental health in Japan. Also, discrimination toward mentally disordered offenders seems to be strong in many countries.
The authors provided a one-hour seminar to offer precise knowledge about forensic mental health to citizens. This kind of attempt is very rare in Japan.
Innovations and breakthroughs
The results suggest people’s biased recognition about mentally disordered offenders will be amended by brief educational intervention. It means that providing precise knowledge can reduce citizens’ discrimination toward mental disorders.
Educational intervention to citizens will be effective for constructing a collaborative society. Developing a series of seminar in school education is also promising.
Mentally disordered offenders mean people who violated a law at least partially due to their psychiatric symptoms such as delusion. How to deal with them is a crucial issue for secure and effective community.
This is a very interesting manuscript aimed to identify participants’ level of awareness and opinion about the current situation of forensic mental health in Japan, and how it can be changed through psychoeducation. Although the manuscript uses simple methodology, the results may have an important impact on negative attitudes and stigma towards mentally ill persons and mentally ill offenders. This kind of research should be encouraged.
