Long-term effect of a name change for schizophrenia on reducing stigma.

BACKGROUND

A name change for schizophrenia was first implemented in Japan for reducing stigma in 2002; however, little is known of its long-term impact.

METHODS

Total 259 students from 20 universities answered an anonymous self-administered questionnaire about their mental health-related experiences, and stigma scales including feasible knowledge and negative stereotypes for four specific diseases, including schizophrenia (old and new names), depression, and diabetes mellitus. We also asked to choose the old and new names of schizophrenia and dementia among ten names for mental and physical illnesses and conditions.

RESULTS

The participants had more feasible knowledge and fewer negative stereotypes for the new name of schizophrenia than the old name, but were still significantly worse than for depression and diabetes mellitus (p < 0.01). Direct contact experiences with those who have mental health problems were associated with feasible knowledge for schizophrenia but not negative stereotypes (β = 0.13, p = 0.020). The rate of correct responses for the old and new names of schizophrenia was significantly lower than that of dementia (41 vs. 87%, p < 0.001). Mental health-related experience from media was associated with the recognition of name change for schizophrenia (p = 0.008), which was associated with less feasible knowledge for new name of schizophrenia.

DISCUSSION

The name change of schizophrenia has reduced stigma since 12 years have passed. More effective campaigns, educational curricula, and policy making are needed to reduce stigma toward schizophrenia.
