Criteria and Concurrent Validity of Adult ADHD Section of the Psychiatry Research Interview for Substance and Mental Disorders

Abstract

Objective: Prevalence of ADHD in adults is around 2% to 4%. Comorbidity is frequent in ADHD; 75% of patients develop a comorbid disorder across life span, substance use disorder (SUD) being one of the most prevalent. Method: A case-control study was performed to check the criteria and concurrent validity of psychiatric research interview for substance and mental disorders (PRISM) adult ADHD section. Validation was done comparing PRISM with the Conners’ Adult ADHD Diagnostic Interview for Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.). A convenient sample ( N = 80) participated, 40 had diagnosis of SUD and ADHD and 40 had diagnosis of SUD without ADHD. The statistics hypothesis was bivariant, and the confidence level was 95%. Results: Kappa index concordance was .78, sensitivity of PRISM adult ADHD module was 90%, specificity was 87.5%, positive predictive value was 87.8%, and the negative predictive value was 89.7%. Conclusion: PRISM has good psychometric properties to detect ADHD associated with SUD.
