Clinical reappraisal of the composite international diagnostic interview version 3.3 in Qatar's National Mental Health Study

Abstract

Abstract Objectives Lifetime DSM‐5 diagnoses generated by the lay‐administered Composite International Diagnostic Interview for DSM‐5 (CIDI) in the World Mental Health Qatar (WMHQ) study were compared to diagnoses based on blinded clinician‐administered reappraisal interviews. Methods Telephone follow‐up interviews used the non‐patient edition of the Structured Clinician Interview for DSM‐5 (SCID) oversampling respondents who screened positive for five diagnoses in the CIDI: major depressive episode, mania/hypomania, panic disorder, generalized anxiety disorder, and obsessive‐compulsive disorder. Concordance was also examined for a diagnoses of post‐traumatic stress disorder based on a short‐form versus full version of the PTSD Checklist for DSM‐5 (PCL‐5). Results Initial CIDI prevalence estimates differed significantly from the SCID for most diagnoses (χ12 = 6.6–31.4, p = 0.010 < 0.001), but recalibration reduced most of these differences and led to consistent increases in individual‐level concordance (AU‐ROC) from 0.53–0.76 to 0.67–0.81. Recalibration of the short‐form PCL‐5 removed an initially significant difference in PTSD prevalence with the full PCL‐5 (from χ12 = 610.5, p < 0.001 to χ12 = 2.5, p = 0.110) while also increasing AU‐ROC from 0.76 to 0.81. Conclusions Recalibration resulted in valid diagnoses of common mental disorders in the Qatar National Mental Health Survey, but with inflated prevalence estimates for some disorders that need to be considered when interpreting results.
