This article describes the initial validation of the Diagnostic Assessment Research Tool (DART), a modular semistructured interview to facilitate diagnosis of various disorders among adults corresponding with the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). In this study, the construct, convergent, and discriminant validity of DART modules for anxiety disorders, depressive disorders, obsessive-compulsive disorder, posttraumatic stress disorder, and substance-related and addictive disorders was assessed among a sample of 610 participants in a clinical outpatient setting. The data indicated excellent construct validity among DART modules assessed. Individuals with and without DSM-5 diagnoses identified via the DART had significant between-group differences on self-report measures corresponding to these diagnoses. Follow-up logistic regressions supported convergent validity for all diagnostic categories assessed. Discriminant validity was established for the majority of diagnostic categories assessed. High rates of interrater agreement in a small subsample (n = 15) were observed for the various diagnostic categories of the DART (88% average agreement). The results of the present study provide initial support for the DART as a useful tool to aid in the assessment of several major diagnostic categories corresponding with DSM-5 disorders.
