Summary

The World Health Organization Composite International Diagnostic Interview (CIDI) is a fully structured diagnostic tool designed for lay interviewers to assess the prevalence of mental and substance use disorders. Earlier versions, such as the CIDI 3.0, demonstrated acceptable individual-level concordance with clinical assessments based on DSM-IV criteria (Haro et al. 2006). The latest iteration (CIDI 5.0) has been updated to operationalize DSM-5 criteria.

Recent evidence from a large-scale, community-based national study in Qatar suggests that under DSM-5 criteria (Khaled et al. 2024), after recalibration, the CIDI 5.0 maintains high specificity (91.9% for MDD, 94.7% for GAD, and 85.5% for PTSD). Sensitivity suggested CIDI diagnoses aligned closely with clinical "gold standard" diagnoses (51.5% for MDD, 50.7% for GAD, and 77.3% for PTSD). Despite the evidence from Qatar, there remains a lack of evidence regarding the validity of the CIDI 5.0 in population-based studies.

Therefore, this study aims to evaluate the diagnostic validity of the CIDI 5.0 for Lifetime MDD, GAD, and PTSD, using the Structured Clinical Interview for DSM-5 (SCID-5) as the definitive clinical gold standard.

CIDI-5

The World Health Organization Composite International Diagnostic Interview-5th (CIDI-5) is a standardized diagnostic tool used to assess the prevalence of mental and substance use disorders over varying time frames (30 days, 12 months, and lifetime) based on the diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) and International Classification of Diseases 10th edition (ICD-10). Trained interviewers will administer selected modules from the Hong Kong version of the CIDI-5 in a computer-assisted personal interview to measure the outcomes. To validate the diagnoses in the CIDI-5 group, investigators will conduct clinical re-interviews of 3 selected CIDI-5 diagnoses: major depressive disorder (MDD), generalized anxiety disorder (GAD), and post-traumatic stress disorder (PTSD) using the Structured Clinician Interview for DSM-5 (SCID) by a trained mental health professional with previous experience using SCID.
