Summary
A Hindi version of the Diagnostic Interview for Genetic Studies (DIGS) is valid for psychiatric research in India. This Hindi DIGS shows good correlation with other diagnostic tools, supporting its use in genetic and non-genetic studies.
Area of Science:
- Psychiatry
- Psychometric validation
- Clinical assessment
Background:
- The Diagnostic Interview for Genetic Studies (DIGS) is a comprehensive tool for psychiatric research.
- A validated Hindi version is needed for research in India.
Purpose of the Study:
- To investigate the validity and reliability of a Hindi translation of the DIGS.
- To assess its utility for psychiatric genetic and non-genetic research in India.
Main Methods:
- Translation and back-translation of the English DIGS into Hindi.
- Clinical interviews with psychiatric patients using the Hindi DIGS.
- Comparison of DIGS diagnoses with Present State Examination (PSE) and treating psychiatrist diagnoses.
- Assessment of interrater reliability.
Main Results:
- Hindi DIGS diagnoses showed significant correlation with PSE diagnoses (kappa = 0.80) and clinical diagnoses (kappa = 0.56).
- Interrater reliability for the Hindi DIGS ranged from kappa = 0.45 to 1.00.
- Variability in interrater reliability was observed and discussed.
Conclusions:
- The Hindi version of the DIGS is a valid and useful instrument for psychiatric research in India.
- It meets the need for a comprehensive interview schedule for both genetic and non-genetic studies in the region.
