OBJECTIVE: To evaluate the validity of the short form of the Composite International Diagnostic Interview (CIDI-SF) in a nationally representative sample of persons in care for HIV disease in the US. METHODS: In separate interviews, the authors administered four components of the CIDI-SF and the full UM CIDI to 1,489 persons ages 18 to 74 receiving ongoing medical care for HIV, and examined the concordance between the two. RESULTS: The CIDI-SF had lower concordance rates than expected. Results suggest that estimates of mental health disorder based on the CIDI-SF may be confounded by HIV symptomology. CONCLUSIONS: In this population, the CIDI-SF provided useful information about general mental health but was less accurate for providing disorder-specific diagnoses than anticipated. The confounding of HIV symptomology and CIDI-SF disorder raises questions about the accuracy of the CIDI-SF for studies conducted in HIV and other clinical and specialized subpopulations.
