psychiatric case validation
Process of confirming psychiatric diagnoses through standardized clinical assessment or record review.
Full Definition
A quality assurance procedure in psychiatric epidemiology where initially identified potential cases undergo additional clinical evaluation to confirm their diagnostic status. This process typically involves structured diagnostic interviews, clinical record review, or expert clinical assessment to verify that screening-positive individuals truly meet criteria for the psychiatric disorder under study. Case validation is essential for reducing false positive rates and ensuring accurate prevalence estimates, particularly when using administrative databases or brief screening instruments for case identification.
Usage
Usage note: Distinguish from case definition, which defines criteria, versus validation which confirms individual cases meet those criteria.
