OBJECTIVE: Self-stigma in psychiatric patients is an issue deserving both research and therapeutic attention. The objective of the present study was to evaluate the psychometric properties of a Czech version of the Internalized Stigma of Mental Illness (ISMI) scale assessing the levels of self-stigma in individuals with mental disorders. METHODS: It consists of 29 items classified into 5 subscales, namely alienation, stereotype endorsement, perceived discrimination, social withdrawal and stigma resistance. The study group comprised 369 patients with a mean age of 41.5±13.3 years, of whom 210 (56.6%) were females. RESULTS: The most frequent diagnosis was neurotic disorders (46.1%), followed by affective disorders (18.4%), substance use disorders (13.3%), psychotic disorders (10.8%), personality disorders (9.5%) and organic disorders (1.6%). Reliability of the scale was evaluated by internal consistency analysis (α=0.91), the split-half method (Spearman-Brown coefficient: 0.93) and test-retest at 3 weeks from the first measurement (N=17; r=0.90, p<0.05). CONCLUSION: Exploratory factor analysis of the scale was performed, its validity was verified and norms were established that were based on T-scores and sten scores for the entire scale and individual subscales. The Czech translation of the ISMI has adequate psychometric properties.
