Diagnostic disclosure: a tale in two cultures

Area of Science:

• Psychiatry
• Cross-cultural psychology
• Medical ethics

Background:

• Diagnostic communication practices between physicians and patients are believed to vary significantly across cultures.
• Understanding these cross-cultural differences in disclosing psychiatric diagnoses is crucial for effective patient care and ethical practice.

Purpose of the Study:

• To investigate and compare diagnostic disclosure practices for psychiatric patients between Japanese and North American psychiatrists.
• To explore cultural influences on the communication of diagnoses, particularly for severe mental illnesses like schizophrenia.

Main Methods:

• A questionnaire survey was administered to practicing psychiatrists in Japan (N=166) and North America (N=112).
• The survey included six case vignettes to assess diagnostic disclosure decisions.
• Data were analyzed to compare disclosure rates and preferred communication strategies between the two cultural groups.

Main Results:

• High disclosure rates (>90%) for affective and anxiety disorders were observed in both Japan and North America.
• Significant differences emerged for schizophrenia/schizophreniform disorders: 70% of North American psychiatrists disclosed the diagnosis, compared to less than 30% of Japanese psychiatrists.
• Japanese psychiatrists favored vague diagnoses (e.g., neurasthenia), while North Americans discussed differential diagnoses.
• Family notification was common in both cultures, but North Americans required patient consent.

Conclusions:

• Diagnostic disclosure is culturally influenced, particularly for conditions with uncertain prognoses or significant stigma, such as schizophrenia.
• Effective treatments correlate with higher disclosure rates across cultures.
• Culturally constructed views of patienthood significantly shape diagnostic disclosure practices.
