The Content Validity of the Cultural Formulation Interview (CFI)

Area of Science:

• Psychiatry
• Cross-cultural psychology
• Mental health assessment

Background:

• The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) includes the Cultural Formulation Interview (CFI) to address cultural factors in psychiatric diagnoses.
• Assessing the validity of diagnostic tools across different cultural contexts is crucial for equitable mental healthcare.

Purpose of the Study:

• To investigate the content validity of the open-ended items within the Cultural Formulation Interview (CFI) from the DSM-5.
• To evaluate the CFI's suitability for use within the Iranian population.

Main Methods:

• The CFI was translated into Persian, with content validity assessed and items modified by psychiatrists.
• A back-translation process was conducted by two translators.
• The Persian version and its back-translation were submitted for approval to the DSM-5 design workshop.
• Content validity was examined using panel members.

Main Results:

• The overall content validity index (CVI) for the Cultural Formulation Interview was 0.51.
• All items were deemed acceptable.
• Specific items related to cultural perception of context and cultural factors affecting help-seeking exhibited lower content validity ratios (CVR).

Conclusions:

• The Cultural Formulation Interview demonstrates overall acceptable, albeit weak, content validity in its Persian translation.
• Further studies are recommended to strengthen the validity of items concerning cultural perception of context and help-seeking factors within the Iranian population.
