Criteria and concurrent validity of DIVA 2.0: A semi-structured diagnostic interview for adult ADHD

Introduction Attention Deficit Hyperactivity Disorder (ADHD) prevalence in the general adult population is estimated to be between 2–4%. Despite the high prevalence, until recently there was only one validated semi-structured interview available for the accurate diagnostic assessment of ADHD within the adult population: the Conners Adult ADHD Diagnostic Interview for DSM-IV (CAADID). Objectives To examine the concurrent validity of the DIVA 2.0 interview comparing the diagnostic rate with the CAADID interview. To analyse the criterion validity of the DIVA 2.0 in the Spanish language in an adult sample. Aims The aim of this is to study was to evaluate criterion validity of the DIVA 2.0 in an adult sample comparing with the CAADID and other ADHD severity scales. Methods A transversal study was performed to check the criteria and concurrent validity of the DIVA 2.0 compared to the CAADID. Results Forty patients were recruited in an adult ADHD program at a university hospital. The DIVA 2.0 interview showed a diagnostic accuracy of 100% when compared with the diagnoses obtained with the CAADID interview and goods correlations with three self-reported rating scales: the WURS, the ADHD Rating Scale and Sheehan's’ Dysfunction Inventory. Conclusions The DIVA 2.0 has good psychometric properties and is a reliable tool for the assessment of ADHD in adults.
