title: The Effects of Symptoms, Diagnostic Labels, and Education in Psychiatry on the Stigmatization Towards Schizophrenia: A Questionnaire Survey Among a Lay Population in Japan.
abstract: This questionnaire survey was conducted to study the determinants of stigmatization toward schizophrenia in Japan. A total of 1003 persons living in Kumamoto Prefecture (mean age 25.5; SD=14.1) participated in this study through convenience sampling. They read one of four case vignettes about a person with mental illness and answered questions about their attitudes toward the case. Vignettes varied in terms of descriptions of symptoms (schizophrenia vs. depression) and presentation of the diagnostic label of schizophrenia (yes or no). A path analysis was performed to examine the effects of symptoms, diagnostic label, experience of education in psychiatry, and demographic features on stigmatizing attitudes. Results showed that schizophrenic symptoms, diagnostic label of schizophrenia, and experience of education in psychiatry were significantly associated with stigmatization toward the case. Interaction terms of these variables did not show significant association with stigmatization. These results highlight the importance of optimizing education techniques about mental illness so as to avoid cultivating stigmatizing attitudes toward schizophrenia.
