Objectives Stigma against mental illnesses is one of the significant obstacles faced by mental health service users and providers. It can develop at a young age and is also influenced by culture. Youths in Southeast Asian countries are under-represented in mental health research, thus this study aims to explore the dimensions of stigma and social tolerance and examine its correlates in the younger, multiethnic population of Singapore.
Design An online survey collected data with sociodemographic questions, the Attitudes Towards Serious Mental Illness (Adolescent version) Scale, Social Tolerance Scale and an open-text question on words or phrases participants associated with the term ‘mental illness’. Principal component analysis and multiple regression models were conducted to investigate the factor structure of the attitudes and social tolerance scales and their sociodemographic correlates.
Participants Participants included 940 youths aged 14–18 years old who were residing in Singapore at the time of the survey and were recruited through local schools.
Results About a quarter of the students (22.6%) reported participating in mental health awareness campaigns while nearly half (44.5%) associated pejorative words and phrases with the term mental illness. The Attitudes Towards Serious Mental Illness (Adolescent version) Scale yielded five factors while the Social Tolerance Scale yielded two. Ethnicity, gender and nationality were significantly correlated with factors of both scales. Chinese youths showed higher sense of ’physical threat' and lower ’social tolerance' than those of other ethnicities. Females showed more ’wishful thinking', ’social concern' and ’social responsibility' towards the mentally ill than males.
Conclusions The dimensions of stigma and social tolerance are different in Asian cultures compared with Western cultures. Sociodemographic differences in attitudes towards the mentally ill were found among youths living in Singapore. Misconceptions and negative attitudes towards mental illness are common, demonstrating a clear need for effective stigma reduction campaigns.

Strengths and limitations of this study
This study is the first to assess stigma towards the mentally ill in a multiethnic sample of youths residing in Singapore.
Students from six schools in three different regions of the country were included in the study.
The study highlights potential misconceptions Southeast Asian youths have about mental illness which should be addressed in mental health awareness programmes.
Due to the voluntary nature of the study, the attitudes of non-responders towards mental illness may be different from that of participants and was not captured.
Link and Phelan1 defined stigma as existing ‘when elements of labelling, stereotyping, separating, status loss and discrimination co-occur in a power situation that allows these processes to unfold’. Stigma against mental illnesses is one of the significant obstacles faced by mental health service users and providers and can be described as prejudice and discrimination against individuals with mental illness due to lack of knowledge, ignorance or misinformation. Negative attitudes also give rise to the desire for social distance, a form of behavioural discrimination which involves reluctance to interact with persons with mental illness.2 Individuals with mental illness often feel a sense of low self-esteem/well-being as they are rejected and discriminated against by others due to stigma.3 Accordingly, they are reluctant to be identified as having a mental illness, resulting in high rates of treatment avoidance.4 Thus, stigma is one of the greatest barriers to seeking treatment for those with mental illness.5
Negative attitudes towards mental illness are influenced by culture and affect people’s behaviour differently depending on their cultural background. Singapore is a multiethnic island city-state in Southeast Asia with a population of 5.61 million in 2016. The population comprises three main ethnic groups: Chinese (74.3%), Malay (13.4%) and Indian (9.1%), while 3.2% belong to other ethnic groups.6 A nationwide study of the local population in 2009 titled the Singapore Mental Health Study7 highlighted the significant treatment gap for mental illnesses in Singapore. Only 31.7% of people with mental illness were found to have sought help. For disorder-specific help seeking, as many as 96.2% of those with alcohol abuse, 90% of those with obsessive compulsive disorder and 59.6% of those with major depressive disorder did not seek help.8
A follow-up study called the Mind Matters study explored the potential reasons for the large treatment gap.9 Mind Matters was a nationwide study of mental health literacy conducted in Singapore in 2014 by the Institute of Mental Health with a total sample of 3006 Singapore residents. The findings of this study showed low mental health literacy and high stigma among those aged 18–65 years old. However, the study showed that younger age was associated with better mental health literacy and attitudes towards the mentally ill.9 10
While this finding is encouraging, this is not to say that younger people have no stigma towards the mentally ill. Attitudes towards various aspects of mental illness, including its conceptualisation and stigma towards the mentally ill are thought to form at an early age.11 A review of children’s attitudes towards the mentally ill suggested that children as young as 5 years old view those with mental illness more negatively.12 The review showed that younger children show negative attitudes and have less sophisticated conceptualisations of mental illness than older children or adolescents. While older children had better understanding of mental illness as emotional and psychological disturbances, the review suggested that negative attitudes increased with age in both children and adolescents. Studies have also shown that youth are reluctant to interact closely with those with mental illness by indicating desire for social distance.13 14 Furthermore, a review of the epidemiology of child and adolescent psychiatric disorders reports that many psychiatric disorders can manifest early on in life and negatively affect several aspects of a young person’s life15 including poor well-being, self-esteem, social relationships in and out of school and academic achievement. Stigma further compounds these problems by reducing well-being and acting as a barrier to help seeking.16 Therefore, mental health stigma affects young adults and youths of schooling age during an important phase of development in their life.
Few studies have explored the attitudes of Asian youths living in Asia, with even fewer including Malay and Indian youths. Although previous research has largely focused on youths in Western countries, their findings are limited due to the lack of generalisability to Asian cultures. Asian values of collectivism are associated with higher levels of stigma17 and cultural factors may affect desire for social distance.18 Young Asians also live in changing times and cultures and antistigma approaches used for adults or Western youths may not be relevant to them. Studies of Chinese youths in Singapore showed that some youths believed in the Asian physiological explanation of mental illness (eg, traditional Chinese beliefs of a body out of balance or harmony) or attributed mental illness to religious and supernatural influences.19 These beliefs could be related to some youths’ preference for seeking help from Traditional Chinese Medicine physicians.20 Although participants in these studies also showed beliefs in psychological causes of mental illness and preference for seeking help from mental health professionals, the findings suggest that one’s cultural background may influence one’s views of mental illness. However, stigma and social distance have not been well studied among youths in Singapore. More importantly, no studies appear to have included youths from the other two main ethnic groups in Singapore—Malay and Indian—and they are under-represented in mental health literacy research.
Thus, the aims of the current study were to explore the factor structure of two scales measuring youth stigma, the Attitudes Towards Serious Mental Illness—Adolescent Version (ATSMI-AV) Scale21 and the Social Tolerance Scale.22 It also aims to examine their correlates in the younger, multi-ethnic population of Singapore and determine the amount of exposure local youths have to mental health awareness campaigns.
Participants were youths aged 14–18 years old residing and studying in Singapore at the time of data collection. The youths were recruited from schools after ethics approval was obtained. Students in grades secondary three to second year junior college (equivalent to grades 9 to 12 of high school in the USA) were included in the study. The inclusion criteria comprised those who were literate in English and were able to use the internet to complete the online survey.
The target sample size was calculated based on Watson et al’s21 study where the mean score on the ATSMI-AV ranged from 1.79 to 2.6, with SD ranging from 0.65 to 0.95. To reach significance level at p<0.05, acceptance of margin of error at 0.03 level and taking into account 25% refusal rate and 15% missing data, the desirable minimum sample size ranged from 666 to 990. Using a conservative estimate, a sample size of 1000 was selected for the study. A total of 1000 responses were recorded on the online survey.
Approval was obtained from the National Healthcare Group Domain Specific Ethics Review Board and the Ministry of Education to approach youths for the study. Ten schools registered with the Ministry of Education were approached using a convenience sampling method and six agreed to participate in the study. The participating schools included both single-sex and mixed-sex schools based in the North, North-East and Central Regions of Singapore and were a mix of government-run, government-aided and independent schools. To reach our target age group, the schools involved were secondary schools (secondary 3–5; 14–17 years old) and junior colleges (17–18 years old). Of the participating schools in the North Region, one was a mixed-sex junior college (government run) and one a mixed-sex secondary school (government run). The participating North-East schools comprised one girls’ secondary school (government aided, autonomous) and one mixed-sex secondary school (government run). In the Central Region were one girls’ secondary school (independent) and one mixed-level school comprising both a boys’ secondary school and mixed-sex junior college (independent) in the southern area. Approximately 2500 students were informed of the study via school notification boards, e-mail blasts and presentations at the schools. Written informed consent was obtained from both the participant and their parent/guardian before participants were recruited for the study. Consent forms were distributed to students via the schools so that anonymity and confidentiality were maintained. A link to the online survey was sent to participants via their preferred e-mail address, and they were allowed to complete it in their own time in a place that they were comfortable in. E-mail reminders were sent to participants who had volunteered but not completed the survey and those who completed the survey were reimbursed with SG$15 iTunes vouchers.
The online survey was designed using the online survey tool, QuestionPro, which allowed the survey to end automatically when the quota of 1000 completed responses was reached. It was launched and completed in 2016 with 1016 surveys started and 1000 surveys completed. The survey consisted of sociodemographic questions as well as scales pertaining to attitudes towards the mentally ill. It also included an open-text question where participants could list words or phrases they associated with the term ‘mental illness’.23 The survey took 10 to 20 minutes to complete.
Questions relating to sociodemographic background were included to gather information on age, gender, ethnicity, education level and nationality. Nationality was divided into two groups: Singapore citizens and permanent residents who are defined as citizens of other countries but are permitted to live and work in Singapore.
The ATSMI-AV Scale is a validated 21-item self-report scale that measures attitudes towards mental illness. Responses to statements are based on a five-point Likert scale where one indicates ‘completely disagree’ and five indicates ‘completely agree’. The scale explores perceptions of violence, social avoidance, embarrassment if one were diagnosed as having a mental illness and personal invulnerability to mental illness. Previous research identified five factors comprising threat, social control/concern, wishful thinking and categorical thinking and out of control.21 A factor-based scale score ranging from 1 to 5 may be calculated for each factor, with higher scores indicating higher levels of stigma towards mental illness. The first factor titled threat (eg, ‘Mentally ill people scare me’) refers to the fear of direct harm to oneself or one’s reputation due to contact with mentally ill individuals and consists of six items. The second factor titled social control/concern (eg, ‘I sometimes worry that I may have a mental illness’) consists of five items and pertains to concerns about being diagnosed with a mental illness and subsequently labelled by society. The third factor titled wishful thinking (eg, ‘People who are mentally ill could be well if they tried hard enough’) refers to unrealistic thoughts towards recovery from mental illness and consists of four items. In contrast, the fourth factor titled categorical thinking (eg, If you become mentally ill your life is pretty much over’) refers to all-or-nothing thought patterns towards the concept of mental illness and consists of four items. The fifth factor titled out of control (eg, ‘Mentally ill people tend to be more violent than other people’) consists of two items and relates to the association between mental illness and deviant behaviour. As the previous study was conducted on a Western population and stigma against mental illness is known to vary across cultures, it was necessary to examine the psychometric properties of the ATSMI-AV in an Asian population.
Social Tolerance Scale22
The Social Tolerance Scale measures social tolerance through desire for social distance (seven items) and social responsibility for mental health issues (four items). Items are rated on a five-point scale ranging from ‘strongly agree’ to ‘strongly disagree’. Higher scores indicate higher levels of stigma towards mental illness. According to the scale developers, the Cronbach’s alpha for the scale was 0.87. However, a factor analysis was warranted to verify the factors for the Social Tolerance Scale in the present sample.
Words and phrases associated with ‘mental illness’
An open-text question asked participants to list at least three words or phrases that are associated with the term ‘mental illness’. For example, a participant may indicate words/phrases such as, ‘crazy’, ‘violent’ or ‘very dangerous’.
In total, 1000 responses were recorded in the online survey database of which 940 responses were included for analysis after data cleaning. The 60 excluded cases were removed due to unreliable data such as dropout/withdrawn cases, pattern answers and duplicate submissions. The survey responses kept for analysis were at least 80% complete. The means and SD were calculated for continuous variables, while the frequencies and percentages were calculated for categorical variables. The factor structures of the ATSMI-AV and Social Tolerance scales were examined using exploratory principal component analysis (PCA) with orthogonal, varimax rotation. Exploratory PCA was used as the factors of the ATSMI-AV and Social Tolerance scales have not been adequately analysed across cultures. For example, there was only one study that conducted factor analysis of the ATSMI-AV in a Western population. Thus, exploratory PCA was used to examine the factors of the ATSMI-AV and Social Tolerance scales in a multiethnic Asian culture. Factor extraction was assessed based on the following criteria: Kaiser-Meyer-Oklin (KMO) value (>0.60), Barlett’s Test of Sphericity (p<0.001), Kaiser-Guttmann criterion (eigenvalue >1) and factor loadings(>0.40).
A series of multiple regression models were performed to examine the sociodemographic (age, gender, ethnicity, education and nationality) correlates of the ATSMI-AV and Social Tolerance subscales. Data were analysed with the Statistical Package for Social Sciences V.23.0 (SPSS) with statistical significance level set at 0.05 for all procedures. Basic content analysis was used to analyse the qualitative data from the open-text question.23 The data were coded twice by one researcher to identify the common themes. A chi-square test was used to examine the relationship between self-reported exposure to mental health awareness events and endorsement of the different qualitative themes.
The sociodemographic breakdown of the sample is shown in table 1. The mean age of the sample was 15.9 years (SD=1.46) and 443 (47.1%) participants were female which is comparable to the overall student population targeted (mean age=15.15 years, females=49.2%).24 Of the 940 students, only 212 (22.6%) said that they had taken part in a mental health awareness event.
Analysis of the qualitative data gathered from participants asked to ‘list words they think of when they hear the words ’mental illness'’ yielded three main themes: (1) pejorative associations; (2) names of disorders and (3) sympathy. Of the respondents 418 (44.5%) listed at least one pejorative word or phrase such as ‘crazy’, ‘weird’, ‘scary’, ‘stupid’, ‘should avoid’ and ‘dangerous’. Local slang such as ‘siao/gila (meaning crazy/insane)’ were also found. Names of disorders including ‘anxiety’, ‘OCD’ and ‘schizophrenia’ were listed (26%). Sympathy towards the mentally ill such as ‘pitiful’, ‘sad’, ‘need love/care’ were also expressed (25.5%). The top five most commonly used words are listed in table 2. No significant differences in the types of words listed were found between participants who self-reported partaking in mental health awareness events and those who did not. The groups did not differ in pejorative associations (40.1% vs 45.9%, χ2(1)=2.25, p=0.13), naming mental illnesses (23.6% vs 26.8%, χ2(1)=0.89, p=0.35) or in expressing sympathy (24.5% vs 25.8%, χ2(1)=0.15, p=0.70).
The first PCA was conducted on the 21-item ATSMI-AV. Results of the PCA with varimax rotation yielded five factors with eigenvalues greater than 1. Two items (‘I sometimes worry that I may have a mental illness’ and ‘I don’t think that there is any way that I can become mentally ill’) were weakly correlated and did not load onto any factors; these were excluded from subsequent analyses. The factorability of the remaining 19 items was supported by KMO value of 0.82, Barlett’s Test of Sphericity (p<0.001) and Cronbach’s alpha (0.78). The five factors accounted for 49.07% of the variance. Question items and corresponding loadings are presented in table 3.
The four items that loaded onto the first factor were related to the perception that mentally ill individuals are threatening (eg, Mentally ill people scare me). Thus, the first factor was labelled as ‘physical threat’, Cronbach’s alpha (0.76). Four items loaded onto the second factor labelled ‘wishful thinking’, Cronbach’s alpha (0.73), which was related to unrealistic perceptions about the recovery from mental illness (eg, People who are mentally ill could be well if they tried hard enough). Four items also loaded onto the third factor, labelled ‘categorical thinking’, Cronbach’s alpha (0.60), which reflected black or white thinking (eg, If you become mentally ill your life is pretty much over). The three items that loaded onto the fourth factor, ‘label avoidance’, Cronbach’s alpha (0.60) comprised items related to shame towards receiving a mental illness diagnosis or being associated with mentally ill individuals (eg, I would be very embarrassed if I were diagnosed as having a mental illness). The final factor had four items which related to social concerns associated with mental illness (eg, I think that society makes up the diagnosis of mental illness just to control people). Hence, the final factor was labelled as ‘social construction/concern’, Cronbach’s alpha (0.53).
Responses to the survey questions regarding attitudes towards the mentally ill are shown in table 4. Of the participants, 29.8% felt ‘that there really isn’t anything called mental illness’ and 34.3% believed that there are medications that can help those with mental illness. Seven per cent (n=66) of the participants had some missing data in the ATSMI-AV.
The second PCA was conducted on the 11-item Social Tolerance Scale. Results of the PCA with varimax rotation yielded two factors with eigenvalues greater than 1. The factorability of the 11 items was supported by KMO value of 0.86, Barlett’s Test of Sphericity (p<0.001) and Cronbach’s alpha (0.83). These two factors accounted for 53.34% of the variance. Question items and corresponding loadings are presented in table 5.
Six items loaded onto the first factor labelled ‘social distance’, Cronbach’s alpha (0.82), which was related to negative reactions associated with being in close physical proximity with mentally ill individuals (eg, I would be upset if someone with a mental illness always sat next to me in class) or forming close relationships with mentally ill individuals (eg, If I knew someone had a mental illness I would not date them). The second factor had five items related to providing social support to mentally ill individuals (eg, I would visit a classmate in hospital if they had a mental illness). Therefore, the second factor was labelled as ‘social responsibility’, Cronbach’s alpha (0.75). 2.7% (n=25) of participants had missing data for the Social Tolerance Scale.
For the sociodemographic correlates of the ATSMI-AV subscales, only ethnicity was found to be significantly associated with ‘physical threat’. Specifically, Chinese students had a higher sense of ’physical threat' than non-Chinese students (p<0.01). Gender (p<0.05) and nationality (p<0.01) were observed to be significantly associated with ‘wishful thinking’. Females had more wishful thoughts than males while permanent residents had more wishful thoughts than Singaporeans. Gender (p<0.05) and nationality (p<0.05) were also found to be significantly associated with ‘categorical thinking’; males endorsed more categorical thoughts than females while permanent residents had more categorical thoughts than Singaporeans. Only gender was significantly associated with ‘social construction/concern’ where females were found to have greater social concerns than males (p<0.001). None of the sociodemographic variables were associated with ‘label avoidance’.
Table 6 presents the results of the multiple regression analyses for the sociodemographic correlates of ATSMI-AV and Social Tolerance. For the sociodemographic correlates of the Social Tolerance subscales, only ethnicity was found to be significantly associated with ‘social distance’. Specifically, Chinese students had lower tolerance for contact with mentally ill individuals compared with non-Chinese students (p<0.001). Gender and ethnicity were both observed to be significantly associated with ‘social responsibility’; males (p<0.001) and Chinese (p<0.01) students had lower tolerance to engage in supportive action towards others with a mental illness compared with females and non-Chinese students, respectively.
Overall, a large proportion of the participants appear to have misconceptions towards mental illness. The PCA of the ATSMI-AV yielded five factors, ’physical threat', ’wishful thinking', ’social concern', ’label avoidance' and ’categorical thinking'. The PCA of the Social Tolerance Scale yielded two factors, ’social distance' and ’social responsibility' though the items in each factor was not exactly the same as that used by Koller et al.22 Significant associations were found between subscale factors and sociodemographic factors.
While nearly a quarter were able to volunteer names of mental illnesses (26%) and express sympathy for the mentally ill, negative views were most predominant with almost half the sample (44.5%) associating negative words with mental illness. The proportion of participants who listed negative words was marginally smaller in those who reported attending mental health awareness campaigns (40.1% vs 45.9%), but the differences in pejorative associations, naming of mental illnesses and expressing sympathy were not statistically significant. As it is unclear what kinds of mental health awareness campaigns were attended by self-reported attendees, further research into the efficacy of youth mental health campaigns is necessary. ‘Depression/Depressed’ was the most commonly listed word (20.2%) which indicates that youths were familiar with depression as a mental illness. The words ‘crazy’ (18.7%), ‘different’ (15.9%) and ‘weird’ (13.1%) were the next most commonly listed words, supporting the notion that youths still make negative associations with mental illness and educational campaigns are needed to address this area. The fifth most listed word was ‘autism/autistic’ (9.9%) which also highlights that youths were familiar with autism as a mental illness.
With negative views of mental illness, it is not surprising that about half of the respondents (46.2%) said they would be embarrassed if they were diagnosed with mental illness. Nearly a quarter (22.7%) said they would not want others to know if they had a mentally ill relative. Around a third (35.1%) also said their friends would see them as weak if they had a mental illness. This suggests that mental illness is seen as a mark of shame among local youths and something that their peers would stigmatise. This is of concern as fear of stigma is thought to play a key role in the large treatment gap found in the adult population,8 and this could also present as an issue in the youth population. Besides avoiding treatment, youths may also lack social support if they find mental illness to be an embarrassing or taboo topic. This fear of others knowing about one’s mental illness may be linked to collectivist Asian values17 and while changing cultural values is not plausible, changing the view of mental illness as a mark of shame may be important for interventions.
Despite this, more than 80% of students said they ’would visit a classmate in hospital if they had a mental illness' (83.6%), ‘tell a teacher if a student was being bullied because of their mental illness’ (89.6%) and ‘stick up for someone who had a mental illness if they were being teased’ (87.5%). Only 3.5% had the misconception that mental illness is contagious and approximately half (52.1%) were open to volunteering for mental health-related causes. While these positive findings are encouraging, there is room for improving mental health knowledge and reducing stigma among youths—possibly with the help of campaigns targeted towards youth that are age and culture appropriate.
A review by Corrigan et al25 suggests that education-based interventions are more effective in changing attitudes and behaviour in adolescents than contact with a mentally ill person, though both methods have significant effects. In-person contact appears to be more effective than video contact as the former yields significant changes in both attitude and behavioural intention while the latter only creates change in attitudes. However, this difference may be negligible as another review by Mehta et al26 suggests that social contact in interventions only affect short-term outcomes and show little to no effect in the midterm or long term. The review found that mental health awareness interventions generally had a medium-sized effect on knowledge outcomes (range 0.51 to 11.77) and a small effect on attitudinal outcomes (range −0.17 to −0.45) in the midterm to long term.26 Considering the conservative local culture of Singapore, gaining participant and/or parental consent for youths to attend interventions with social contact may be challenging. In light of these challenges and the lack of evidence for longer term benefits of social contact, education-based interventions may be the most practical approach for local mental health awareness campaigns with video-based contact if needed. Emphasis should be placed on developing the educational aspects of awareness campaigns, both for longer term outcomes and to target the low mental health literacy in the local population.10 Interventions should also be run regularly or even as part of school curriculum as opposed to isolated events to ensure that the effect is maintained. Although challenging, efforts should be made to measure the long term outcomes of these interventions. Dedicated experimental studies should be conducted to ensure that interventions are locally relevant and have the desired outcome. Future nationwide studies such as the Singapore Metal Health Study on prevalence and use of mental health services7 and Mind Matters study on mental health literacy9 may be replicated and include components that monitor stigma, mental health literacy and the treatment gap at a population level.
To our knowledge, the ATSMI-AV21 has not been used in the local sample; thus, factor analysis was conducted to explore its components. The items that loaded onto ’wishful thinking' were identical to those by Watson et al.21 ’Social construction/concern' was also the same except for one item ‘I sometimes worry that I may have a mental illness’ which did not load onto any factor in the analysis. Two separate factors were related to threat in the sample (’physical threat' and ’label avoidance') though the items fell under a single overarching factor of threat by Watson et al.21 The remaining items in the out of control and categorical thinking factors in the study by Watson et al21 were combined into one factor in this sample as ’categorical thinking'.
The factor analysis of the Social Tolerance Scale also produced a slightly different factor structure from that suggested by Koller et al.22 The authors suggested seven items for social distance and four for social responsibility. The two factors found in our analysis were similar except for one item (‘I would visit a classmate in hospital if they had a mental illness’) which loaded onto the ’social responsibility' factor instead of ’social distance', unlike the findings by Koller et al.22 This difference in factor structure may be indicative of cultural differences in social norms between Singaporean and Western youth populations and that social distancing may thus present differently. As the sample largely consists of youths from the main Asian ethnic groups in Singapore (Chinese, Malay and Indian), further research in other Asian samples, including adults, is necessary to investigate if cultural differences are truly present.
In terms of the sociodemographic correlates, ethnicity was correlated with one of the ’physical threat' stigma subscale factors and both subscales for social tolerance. While collectivist Asian values are linked with higher levels of stigma,17 it appears that there are differences between the Asian ethnic groups. Those of Chinese ethnicity felt more ’physical threat', had more desire for ’social distance' and less ’social responsibility' than those of other ethnicities. Some of these findings are similar to those found in the adult population10 where Indian and Malay participants scored lower on a social distance measure despite having higher personal stigma. Corrigan et al27 found that individuals from minority ethnic groups are less likely to support prejudicial attitudes about mental illness. They postulated that this was because people from minority ethnic groups experience mental health stigma more harshly than those in the majority group28 and appear less likely to endorse prejudice about mental illness.29 Another possible explanation is the Chinese concept of ‘face’ which describes a person’s moral standing in society. Having a mental illness may be a mark of ‘losing face’ which can greatly affect one’s access to social capital and bring shame to oneself and one’s family.30 Although collectivist constructs of ‘face’ exist in many Asian ethnic groups, some researchers argue that the Singaporean concept of ‘face’ presents uniquely to the country and that Chinese Singaporeans place more emphasis on ‘saving face’ than the other ethnic groups despite all participants residing in the same country.31 Those of Chinese ethnicity may thus feel more threatened by mental illness as a mark of shame, which in turn leads to greater feelings of physical threat, more desire for social distance and less sense of social responsibility towards the mentally ill.
Gender differences were found on three ATSMI-AV subscales and for social responsibility. The gender differences for ATSMI-AV subscales in our sample were different to those found by Watson et al.21 They found that boys scored higher on threat, a finding that was not replicated here. However, males in our sample did endorse more ’categorical thinking' and Watson et al21 had similar findings with males scoring higher on categorical thinking, a factor which shared some common scale items. Males also scored lower for ’social responsibility' than females, suggesting they were less likely to endorse supportive action towards the mentally ill. Conversely, females showed more ’social concern' and ’wishful thinking' than males. Ng and Chan’s32 study on Hong Kong secondary school students revealed similar findings with females showing higher benevolence towards the mentally ill and males showing more stereotyping, restrictive, pessimistic and stigmatising attitudes towards mental illness. Female adults in Singapore also scored lower for stigma in previous nationwide studies.10
Differences between youths with Singaporean citizenship and permanent residents were also found. Permanent residents endorsed more ’wishful thinking' and ’categorical thinking'. A possible explanation for this finding could be that permanent residents may constitute a mix of different foreign ethnicities including those of the main Singapore ethnic groups. Thus, permanent residents may be classified as a heterogeneous group but actually have diverse views.
The findings of this study should be considered in light of its limitations. First, the voluntary nature of the study may create bias in the responses as students who refused to participate may hold more prejudicial attitudes towards mental illness. Second, despite the anonymous nature of the survey, the participants may have shown social desirability bias when responding to the questions, particularly if they felt that their schools had access to their data. Lastly, the schools were not sampled across all regions and were not representative of all schools in Singapore.
Despite the limitations, the present study has notable strengths which include the large sample size and inclusion of the different ethnic groups which was absent from previous studies involving Singaporean youths. It is also one of the few, if not the only study thus far to investigate the constructs of mental illness stigma and social distance in youths residing in Singapore. Although not all regions of the country were covered, Singapore is a small city-state (719.1 km²) and students were recruited from schools across three of the five regions of Singapore. Furthermore, the sample was similar to the overall target population of school going youth in terms of age and gender distribution. These strengths help increase the generalisability of the findings.
Overall, a significant proportion of youths in Singapore report having little education about mental health which could explain the stigma endorsed by the sample. Future research could use qualitative methods to understand the construct of stigma better in the Asian context, particularly in light of changing values in younger generations. This study could be replicated in the future to evaluate the effectiveness of public education campaigns when they are launched locally.
