Renaming schizophrenia is a potential strategy to reduce the stigma attached to people with schizophrenia. However, the overall associations between renaming schizophrenia and stigma-related outcomes have not been fully elucidated. We conducted a systematic review of studies that empirically examined the outcomes between new or alternative terms and old or existing terms for schizophrenia. We searched for relevant articles in eight bibliographic databases, conducted a Google search, examined reference lists, and contacted relevant experts. We found a total of 2601 reference records, and 23 articles were included in this review. Overall, in countries where schizophrenia has been renamed, the name changes may be associated with improvements in adults' attitudes toward people with schizophrenia, and with increased diagnosis announcement. However, studies conducted in countries where schizophrenia has not been renamed report inconsistent findings. In addition, renaming may not influence portrayals of schizophrenia in the media. Most studies included in our review had a risk of bias in their methodology, and we employed a vote-counting method to synthesize study results; therefore, the impacts of renaming are still inconclusive. Future studies are needed to address the following issues: use of univariate descriptive statistics, adjustment for confounding variables, use of reliable measures, and employing a question that addresses the image of split or multiple personalities. Evidence is limited regarding the associations between renaming and stigma experienced by both people with schizophrenia and their families (e.g., perceived stigma, self-stigma, discrimination experience, and burden). Further research in these populations is needed to confirm the effects of renaming schizophrenia.
