Renaming schizophrenia: a Japanese perspective.

Area of Science:

• Psychiatry
• Mental Health Research
• Sociolinguistics in Medicine

Background:

• Schizophrenia's historical term, "Seishin Bunretsu Byo" (mind-split-disease), carried significant stigma.
• Negative perceptions were exacerbated by past inhumane treatment and the term's ambiguity.
• Advances in schizophrenia research highlighted the need for a more accurate and less stigmatizing nomenclature.

Purpose of the Study:

• To evaluate the impact of renaming schizophrenia in Japan to "Togo Shitcho Sho" (integration disorder).
• To assess the effectiveness of the new term in reducing stigma and improving clinical practice.
• To examine changes in patient diagnosis disclosure and understanding of the disorder.

Main Methods:

• The study involved a nationwide survey in Japan following the 2002 renaming of schizophrenia.
• Data collection occurred seven months post-renaming to assess term replacement.
• Surveys and analysis of clinical practice changes were conducted over three years, including a specific prefecture study.

Main Results:

• Within seven months, the new term "Togo Shitcho" was adopted in approximately 78% of cases.
• Patient diagnosis disclosure rates increased from 36.7% to 69.7% within three years.
• 86% of psychiatrists found the new term more suitable for patient communication and explaining modern concepts.

Conclusions:

• The renaming of schizophrenia to "Togo Shitcho Sho" was successful in replacing the old term and reducing stigma.
• The change facilitated better communication of diagnosis to patients and adoption of the vulnerability-stress model.
• This initiative improved clinical practice and patient understanding, aligning with modern psychiatric frameworks.
