Introduction: Stigmatizing attitude toward patients with severe mental disorders is one of the main obstacles of improving the mental health of societies. Media plays an important role in how the public views mental health issues. Thus, we have performed this study to investigate the Iranian theater artists' mental health status, and their view toward patients with severe mental disorders.

Methods: This cross-sectional study was performed via an online anonymous survey including the Social Distance Scale and the Dangerousness Scale measuring the attitude of participants toward patients with severe mental disorders, and the 28-item General Health Questionnaire (GHQ-28). It was disseminated to artists who had the experience of working in theater in the past year in Iran.

Results: Our survey was responded by 104 artists. Social Distance Scale scores' mean was 10.67 (scores can range from 0 to 21) and the Dangerousness Scale scores' mean was 28.87 (scores can range from 8 to 56); higher scores indicate worse discrimination. Our participants' strongest fears were to let someone with a severe mental disorder to take care of their children, and for these groups of patients to obtain a hunting license. Twenty-six (25%) participants were at risk of moderate to severe anxiety, and 18 (17.3%) participants were at risk of moderate to severe depression.

Conclusion: By and large, our participants did not have a positive attitude toward patients with severe mental disorders. Providing the knowledge of mental health issues can help the general public to be more tolerant of the mentally ill and specifically, theater can be employed to fight stigmatizing mental health issues by educating its audience.

Introduction

Stigma is defined as disapproval of an individual or group based on their distinguishing characteristics. Stigmatizing mental health issues exists on three levels: individual, interpersonal, and institutional. It stems from misconception and prompts falsely applied stereotypes, prejudice, and discrimination (1, 2).

Discrimination takes different forms and may emerge as social disapproval and exclusion. It may lead to decline in social status, worsening the illness, aggression, interpersonal conflicts, and isolation. Furthermore, stigma may encourage substance abuse and reluctance toward treatment. Consequently, people with mental health issues do not just have to carry the burden of their symptoms but also deal with reduced quality of life (13).

Previous studies have reported that stigma invigorates the general public to withhold help from minorities (4). Protest, education, and contact are the three suggested components against stigma (5). Some studies have indicated that educating the public with an accurate perception of mental health issues makes stigmatizing less likely (6). Several studies have reported improved attitudes as the outcome of educational programs, which can be used for a wide age range (610). There also have been reports of positive results attributed to the public being in contact with patients with severe mental disorders (11).

Media plays a vital role in how the public views mental health issues, and its imprecise representation in television and films has been reinforcing the negative stereotypes. It has been portraying the mentally ill as potentially dangerous people to society (12).

As theater creatively interacts with its audience, it can either be used to fight mental disorders stigma or prompt the negative attitude toward patients with severe mental disorders. Several studies indicated the theater's positive effects on reducing stigma among teenagers and young adults (1319). There have been reports of the possibility for the role of the dramaturg (13), live presentations (14), applied drama (15), performing arts (16), and theatrical presentations (17) in reducing stigma. A review for evaluating the impact of mass media interventions including film, photographs, radio and comics reported that art interventions are generally effective when they use multiple art forms, but with a small effect (18).

Previous studies have reported that significant rates of moderate to severe mental health issues exist among artists in different fields (1921) which probably affects their work and what they present to the public. There also have been reports that one's mental health status, especially experiencing depressive symptoms, can affect their attitude toward the mentally ill (22). Considering the significant effect of the theater on public attitude toward patients with severe mental disorders, we conducted this study to evaluate a group of Iranian theater artists' mental health status and attitude toward this group of patients, and to investigate the possible link between these items.

Methods

Design

This cross-sectional study was performed via an online anonymous survey including the Persian versions of three questionnaires: the Social Distance Scale, the Dangerousness Scale, and the 28-item General Health Questionnaire (GHQ-28).

Data collection

The survey was open from June of 2021 until June of 2022, and was disseminated to 340 artists through social media (via email and chat applications). We used the snowball sampling method, starting at art centers and art schools based in Tehran. Thereafter artists across the country were contacted. The sample size was calculated with CI = 95% (confidence interval), p = 0.24 (population proportion) (23) and d = 0.09 (sampling error). The inclusion criteria were being over the age of 18, and having the experience of working in theater in the past year.

Tools

The Social Distance Scale (first developed by Link) and the Dangerousness Scale (first developed by Park) both present cases of patients with severe mental disorders and measure the attitude toward the target person. The Social Distance consists of seven questions and uses the Likert scale as “definitely willing/ probably willing/ probably not willing/ definitely not willing.” The Dangerousness Scale consists of eight questions and uses the Likert scale as “strongly agree, rather agree, agree, nor agree or disagree, disagree, rather disagree, and strongly disagree”. Higher scores indicate worse discrimination (24). Ranjbar Kermani et al. assessed and determined the validity and reliability of the Persian versions of the Social Distance Scale (Cronbach's alpha coefficient: 0.92, test-retest reliability coefficient: 0.89, content validity coefficient: 0.75) and the Dangerousness Scale (Cronbach's alpha coefficient: 0.96, test-retest reliability coefficient: 0.88, content validity coefficients: 0.77) (25, 26).

The 28-item General Health Questionnaire (GHQ-28) includes 28 questions in four subsections measuring the somatic symptoms, anxiety and insomnia, social dysfunction, and depression. Ebrahimi et al. assessed and determined the validity and reliability of the Persian version of the GHQ-28. Its Cronbach's alpha and split reliability co-efficient were 0.78, 0.97 and 0.90 respectively (27).

Ethical considerations

Participants responded to our survey voluntarily and anonymously. Our study was approved by the Institutional Review Board of Iran University of Medical Sciences (Reference: IR.IUMS.FMD.REC.1400.362).

Statistical analysis

Data were analyzed by IBM SPSS Statistics (v. 25.0). To report the frequencies and percentages of categorical variables, descriptive statistics were used, and only valid percentages are reported. The demographic data and the GHQ subscales were compared with the variables of the Social Distance Scale and the Dangerousness Scale, through Chi-Square Test.

Results

A total of 104 artists, within the age range of 18-56, responded to our survey, and more than half (59.6%, N = 62) of them were male. Table 1 presents the participants sociodemographic characteristics in detail.

We have presented the GHQ subscales' score in Table 2. Participants' Social Distance Scale scores ranged from 0 to 21 (Mean: 10.67, Median 10.0, SD: 4.922), and their Dangerousness Scale scores ranged from 11 to 54 (Mean 28.87, Median: 29.00, SD: 10.291). The responses to the Social Distance Scale, and the Dangerousness Scale are presented in Tables 3, 4, respectively.

No significant correlation was found between the demographic data, the GHQ subscales' scores, and the items of the Social Distance Scale, and the Dangerousness Scale.

Discussion

By and large, our participants' attitude toward patients with severe mental disorders was not positive. The Social Distance Scale scores' mean was 10.67 (±4.922), and the Dangerousness Scale scores' mean was 28.87 (±10.291). We found no significant correlation between the demographic data and the Social Distance Scale scores and the Dangerousness Scale scores, probably due to our small sample size. However, previous studies have reported that older age and marital status (being married) were indicators of negative attitude, and younger age, being female, and higher education were indicators of positive attitude toward patients with severe mental disorders (2832).

Among the Social Distance Scale items, the question “What do you think about someone like that person taking care of your children for an hour or two?” received the most negative feedback. This result was unexpected as there has been no substantial report of child abuse by patients with severe mental disorders over the past years. Notwithstanding that prevention of any type of child abuse or assault is a critical issue among all societies, no rationale supports this fear, and it seems to stem from general attitudes. Besides, previous studies have reported that most child abuse perpetrators are among the families or acquaintances (33).

And among the Dangerousness Scale items, the statement “There should be a law forbidding a former mental patient the right to obtain a hunting license” received the most negative feedback. Over the past years in Iran, no murder report with a gun by patients with severe mental disorders has been recorded, which may be because private ownership of guns is illegal. The mass media has propagated the use of guns by these patients over time, especially in the United States of America, and this false image has affected the attitude of different populations and societies. Moreover, previous studies have reported that it is more likely for patients with severe mental disorders to become the victim rather than becoming the offender (34).

As we gathered, 26 (25%) participants were at risk of moderate to severe anxiety, and 18 (17.3%) participants were at risk of moderate to severe depression. In total, 15 (12.6%) participants were at risk of having moderate to severe mental disorders. Whereas, in a study conducted by Noorbala et al. among Iranian general population, using the same cut-offs, it was reported that 29.50% were at risk of anxiety, and 10.39% were at risk of depression. In total, 23.44% of the general population were suspected of moderate to severe mental disorders (23). Low rates of mental disorders among our participants are probably for the reason that people with low levels of anxiety and social dysfunction (a consequence of depression) enter the field of theater, and also, we had a small sample size. Moreover, Kegelaers et al. reported from the Netherlands, that 30% of the electronic music artists (19) and 51.6% of the classical musicians (20) experienced symptoms of depression/anxiety which is much higher than our result (12.6%). In addition, Topoglu et al. reported from Turkey, that 36% of the Turkish state symphony orchestras musicians were at risk of moderate/severe mental health issues, which also holds a higher prevalence than our study (21). All three studies had used the GHQ-12 questionnaire. The difference between our studies was probably due to this fact that the artists working in theater are required to be socially functional to qualify in the field. Also, the GHQ is a screening questionnaire rather than a diagnostic one.

We did not find any significant correlation between our participants' mental health status and their attitude toward patients with psychiatric disorders. However, a study conducted in Finland, reported that dealing with depressive symptoms, leads to a positive attitude toward people with depression (22).

Strengths and limitations

To the best of our knowledge, this is the first study in Iran to investigate the view of the artists working in theater on mental disorders. Our study is limited by a small sample size, social-desirability bias, and participation bias (participating in a study about psychiatric disorder may have also been a reason for holdback). Probably due to our small sample size, no significant correlation was found between the demographic data, the GHQ subscales' scores, the Social Distance Scale scores, and the Dangerousness Scale scores.

Implications for practice, research, and policies

Most anti-stigma interventions and campaigns have been conceptualized using knowledge-attitude-behavior paradigm (18), i.e., experiential learning (learning through reflection on doing), empathy building, interactive and prolonged exposure to anti-stigma content (35, 36).

Further investigations should be done among artists, and if needed, we can provide them with anti-stigma activities and interventions, i.e., workshops, screening films or performing plays about mental disorders, and discussion classes that have been suggested by previous studies for other groups (1318).

Conclusion

We concluded that all in all, our participants do not have a positive attitude toward patients with severe mental disorders. However, we found no significant correlation between the demographic data, the GHQ-28 scores, the Social Distance Scale scores and the Dangerousness Scale scores, which was probably due to our small sample size. Twenty-five percent of the participants were at risk of moderate to severe anxiety, and 17.3% of the participants were at risk of moderate to severe depression. Our participants' strongest fears were to let patients with severe mental disorders take care of their children, and obtain a hunting license. As reported before, providing knowledge of mental health issues can help the general public to be more tolerant of patients with severe mental disorders. Thus, theater can be employed to fight stigmatizing mental health issues by educating its audience through its creative ways.
