Purpose: This study was performed to identify how internalized stigma, anger expression style, and mental health service satisfaction impact on the self-esteem of inpatients with schizophrenia. Methods: For this descriptive correla-tional study, 191 inpatients with schizophrenia participated. They had been admitted to one of six mental hospitals in three areas of South Korea. Data were collected from August 1 to November 30, 2016 using self-report ques-tionnaires and data were analyzed using t-test, one-way ANOVA, Pearson correlation coefficients, and stepwise mul-tiple regression with IBM SPSS 22.0. Results: The significant predictors of self-esteem in inpatients with schizo-phrenia were internalized stigma, anger expression style, and mental health service satisfaction, explaining 36% of the variance in self-esteem. The most significant predictor of self-esteem in inpatients with schizophrenia was in-ternalized stigma. Conclusion: Study findings suggest that a significant reduction in the internalized stigma of in-patients with schizophrenia increases their self-esteem. It is also, necessary to improve adaptive anger expression style and mental health service satisfaction.
