Is Irritability a Top Problem in Youth Mental Health Care? A Multi-informant, Multi-method Investigation

Abstract

Irritability is often described as a common problem affecting youth referred for mental health services; however, little is known about the prevalence and nature of irritability as a focus of treatment. We examined assessment data from a diverse sample of youths (N = 206; ages 7–15; 52% male, 48% female; 33% White, 27% Black, 25% Latinx) referred for outpatient treatment of emotional and behavioral concerns. Caregivers and youths completed nomothetic (standardized checklist) and idiographic (free response) measures at intake. Irritability was identified as a top problem (TP) in 58% of cases, commonly reported by caregivers (38%), youths (42%), or both (23%)—rates that were significantly greater than those of other TP domains (depression, anxiety, ADHD, conduct, and defiance). Further analyses identified clinical correlates of irritability TPs, with results supporting the incremental utility of multiple informants and methods. Findings suggest that irritability is among the most common problems for which families seek youth treatment.
