This study attempted to measure and compare self stigma among schizophrenia and alcohol dependence syndrome patients. Researches related to perceived self stigma in psychiatric disorders generally conducted were neither on a homogenous group of illness nor comparative studies. To the best of our knowledge, it is the kind of first study conducted.
A review of literature reported internalized stigma in schizophrenia patients to be 29.4% and 41.7%, respectively (
15,
32). Literature of the comparative studies on stigma of alcoholism and other psychiatric disorder show that people suffering from alcohol dependence are severely stigmatized (
33-
35). Rohit et al., in his study also reported that substance dependence patients had higher stigma scores than schizophrenia patients (
36). The present study determined internalized stigma in 50% of schizophrenia patients and 66% of ADS patients. The stereotype endorsement (0.01), stigma resistance (0.023), and total ISMI scores (0.21) were found to be statistically significant between the two groups. Compared with the above studies, a high prevalence of self stigma was found in our study, which could be due to the heterogeneity of the sample and differences in severity of illness (
37). Our study also reported that the prevalence of stigma in ADS was higher than schizophrenia. This may be due to the fact that they provoke more social rejection and more negative emotions, they are held much more responsible for their condition, less frequently considered as mentally ill, and at risk of structural discrimination (
35).
The present study reported significant association of self stigma with marital status, education, type of family, and locality among schizophrenia patients whereas self stigma scores were not significantly affected by other socio-demographic variables. Different studies across the world correlating stigma with socio-demographic variables have found contrasting results. In these studies, self stigma was significantly associated with age and male gender (
17) whereas some suggest lack of association with being married, living alone, and education (
38-
40). In addition, in a study by Rohit Garg et al., significantly higher stigma scores were reported in younger patients than older patients. This may be due to the fact that there are more understanding about their friends and more social interactions focusing on self attributes at a younger age (
36). Previous studies also reported more stigma in patients with lower education than those with higher education (
41,
42). It may be due to lower socioeconomic status and poverty in individuals with lower education. They are dependent on others for their employment and placed at the bottom in social hierarchy. This may contribute to a greater degree of social rejection, isolation, and internalization of feelings of stigma (
36).
A study by Jadhav et al., showed higher stigma scores in rural samples than the urban sample. The reason may be that rural subjects showing supportive tolerant attitude as indicated by not covering up the illness, favorable response to living next door, and expecting the full return to normality (
43). The rural individuals experienced more shame, ridicule, and discrimination whereas urban individuals felt the need to avoid and hide their illness in their job application (
44). The reason for no significant association found in our study with respect to other variables may be due to socio-cultural and methodological differences.
The present study reported lack of association with clinical characteristics such as current status and illness duration among schizophrenia patients. Previous studies observed higher stigma scores in patients with longer illness duration and those who were not in remission (
36). A review by Gerlinger et al., reported that age of onset, lifetime number of hospitalizations, and duration of illness had contradictory associations with self stigma (
17). All these factors would be expected to increase the number of symptoms and severity of illness as well as expected to increase the actual stigmatizing responses of others and the person’s stigma (
36). The differences found in our study and previous studies in relation to clinical characteristics could be attributed to different questionnaires used to assess the stigma and differences in the psychosocial factors (
45,
46).
Our study demonstrated that self stigma was significantly related to educational status of ADS patients, whereas none of the other socio-demographic variables had a significant difference. Previous studies suggested that stigma was significantly higher for men, individuals with lower income, lesser education, and individuals previously married as compared to those who had never been married (
47). Consistent with these findings, the literature also suggested that women and persons with higher education and income are generally more accepting of individuals with mental illness. Corrigan et al., hypothesized that lower endorsement of stigmatizing attitudes towards women may be due to a lower rate of social dominance among women and/or higher rates of social empathy compared with men (
48-
50).
Stigma in people with substance use disorders lead to non-completion of treatment, poor recovery, and reintegration processes (
24,
25). Literature also suggested that stigma lead to more difficulties in recovery, greater chances of relapse, and discontinuation of treatment (
51,
52). The above findings conclude that stigma negatively influences the clinical parameters such as duration of the drinking and status of the illness among alcoholics. The present study did not report correlation between clinical variables and stigma among ADS patients. Literature on self stigma is more sparse in addiction and no study showed direct correlation of self stigma among ADS with clinical variables.
The correlation of socio-demographic and clinical variables between schizophrenia and ADS patients with self-stigma in our study reported no significant difference except for gender. This may be due to the fact that male participants outnumber females out of total sample size in this study. The logistic regression analysis showed that locality was found to be a predictor of stigma in schizophrenia, whereas locality and educational status were significant predictors of stigma in ADS in the present study. The results of regression analysis of previous studies demonstrated that current employment, gender, and level of education were not significant independent predictors of self-stigma in schizophrenia (
32). Although the personal characteristics are of lesser importance to the formation of self-stigma, drinking related variables such as duration of drinking problem is found to be an independent predictor of stigma in ADS (
53). Our scan of literature revealed no studies comparing schizophrenia and ADS patients in terms of having self-stigma. Therefore, further studies with large number of patients are needed to clarify whether differences occur between these disorders in terms of self-stigma.
5.1. Conclusion
In conclusion, self stigma is a significant problem in both ADS and schizophrenia patients. It is more severe in individuals living with ADS. Among schizophrenia and ADS subjects with self stigma, male patients were found to be more affected. Internalized stigma can have a negative impact on the well-being as well as psychiatric health and may impede the outcome of individuals suffering from the mental illnesses. Our study shows that locality and educational status are strong predictors of self stigma. Therefore, these factors need to be focused and investigated further to improve the overall quality of life and reduce the stigma.
5.2. Limitations
The sample size was small and the study was cross-sectional. The longitudinal studies with larger sample size would be more reliable to infer causality from the findings. The other limitation is that the study was hospital based. Therefore, the studies in the community may provide more detail and reliable data.
