Self-stigma and schizophrenia: a cross-sectional study

OBJECTIVE: The aim of this study was to investigate the degree of self-stigma in schizophrenia and its association with clinical and demographic factors. PATIENTS AND METHODS: A total of 197 outpatients (54.3% females) diagnosed with schizophrenia spectrum disorders (schizophrenia, schizoaffective disorder, delusional disorder) according to International Classification of Diseases - tenth edition participated in the study. The mean age of the patients was 40.10±11.49 years. All individuals completed the Internalized Stigma of Mental Illness (ISMI) scale and a demographic questionnaire. The disorder severity was assessed by both a psychiatrist (the objective version of Clinical Global Impression - severity scale objCGI-S) and the patients (the subjective version of Clinical Global Impression - severity scale subjCGI-S). Treatment with antipsychotics stabilized the patients. RESULTS: The overall level of self-stigma measured by the total score of the ISMI was 63.32±13.59. The total score of the ISMI positively correlated with the severity of the disorder measured by the objCGI-S and subjCGI-S. In addition, self-stigma positively correlated with the treatment duration and the number of psychiatric hospitalizations. The backward stepwise regression was applied to identify the most significant factors connected to self-stigma. The regression analysis identified the following regressors as the most relevant to self-stigma: the number of previous psychiatric hospitalizations, the severity of the disorder rated by a psychiatrist, and the difference between the objective rating and the subjective rating of the severity of the disorder. CONCLUSION: Outpatients with schizophrenia spectrum disorders, who have undergone a higher number of psychiatric hospitalizations, who dispose of a higher severity of the disorder and show a higher discrepancy between their rating of the severity and the psychiatric rating, showed a greater degree of self-stigma. The management of self-stigma in patients with schizophrenia should be implemented in the routine care.
