Design and field procedures for the clinical reappraisal of the Composite International Diagnostic Interview version 3.3 in Qatar's national mental health study

ObjectivesTo estimate lifetime prevalence, risk, and treatment for mental disorders and their correlates in Qatar's general population for the first time.MethodsWe conducted a national phone survey of 5,195 Qatari and Arab residents in Qatar (2019–2022) using the Composite International Diagnostic Interview Version 3.3 and estimated lifetime mood and anxiety defined diagnoses. Survival‐based discrete time models, lifetime morbid risk, and treatment projections were estimated.ResultsLifetime prevalence of any disorder was 28.0% and was associated with younger cohorts, females, and migrants, but lower formal education. Treatment contact in the year of disorder onset were 13.5%. The median delay in receiving treatment was 5 years (IQR = 2–13). Lifetime treatment among those with a lifetime disorder were 59.9% for non‐healthcare and 63.5% for healthcare; it was 68.1% for any anxiety and 80.1% for any mood disorder after 50 years of onset. Younger cohorts and later age of onset were significantly predictors of treatment.ConclusionsLifetime prevalence of mental disorders in Qatar is comparable to other countries. Treatment is significantly delayed and delivered largely in non‐healthcare sectors thus the need for increased literacy of mental illness to reduce stigma and improve earlier help‐seeking in healthcare settings.

“…Briefly, the survey was conducted via telephone interviews and targeted Arabic-speaking residents of Qatar (Khaled et al, 2023). A stratified multi-stage sampling procedure was used to draw a representative sample of Qatari nationals and non-Qatari (Arab) residents for the study sample (Khaled et al, 2023). The survey was directed to male and female respondents aged 18 and above who lived in Qatar during the survey reference period.…”

“…As the vast majority (98%) of adults in Qatar have at least one cell phone, the frame was expected to provide excellent coverage for this target population (SESRI Omnibus, 2019). As described in detail elsewhere in this issue, we weighted the sample to account for variation in probabilities of selection, variation in response rates, and poststratification calibration (Khaled et al, 2023)…”

ObjectivesLifetime 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.MethodsTelephone 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).ResultsInitial CIDI prevalence estimates differed significantly from the SCID for most diagnoses ( = 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 = 610.5, p < 0.001 to = 2.5, p = 0.110) while also increasing AU‐ROC from 0.76 to 0.81.ConclusionsRecalibration 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.

“…The second component comprised a clinical reappraisal, which was carried out using telephone follow‐up interviews of a subset of the original survey interviews ( n = 485) to assess the diagnostic consistency of core modules of the newly translated and adapted Arabic version of the CIDI against independent clinical diagnoses by trained clinicians based on the Structured Clinical Interview for DSM‐5 (Amro et al., 2023). Results from the clinical validation component of this study constitute the basis of another paper in this issue (Khaled et al., 2023).…”

BackgroundWe provide an overview of Qatar's first epidemiological study on prevalence, predictors, and treatment contact for mood and anxiety disorders.AimsWe highlight the importance of the three‐pronged study, its aims, and its key components.Materials & MethodsThe first component comprised a probability‐based representative survey of Qatari and non‐Qatari (Arab) adult males and females recruited from the general population and interviewed using the International Diagnostic Interview (CIDI version 3.3). The second component, a clinical reappraisal study, assessed concordance between diagnoses based on the CIDI and independent clinical assessments conducted by trained clinical interviewers. The third component comprised a resting‐state functional magnetic resonance imaging study of healthy survey respondents who were matched to patients with psychosis.Results5000 survey interviews provided data on prevalence and treatment of common mental disorders. Clinical re‐interviews (N = 485) provided important diagnostic validity data. Finally, state‐of‐the art structural and functional brain markers for psychosis were also collected (N = 100).DiscussionDescriptive epidemiological data were collected to inform future mental health priorities in Qatar and situates these within a global context.ConclusionThe study fills important gaps in regional and global estimates and establish necessary baseline to develop comprehensive risk estimates for mental health in Qatar’s young population.
