Title: Integrating Ratings of Child Psychopathology across Multiple Informants

Abstract: One of the most significant challenges facing researchers and practitioners who assess child psychopathology is how to integrate information about a child’s symptoms from multiple sources when those sources provide discrepant ratings (De Los Reyes & Kazdin, 2004). It is common to obtain ratings for a single target child from informants such as parents, teachers, and peers, but it is less clear how to combine the information provided by multiple informants to derive an integrated measure of the psychopathology trait of interest that is not confounded with informants’ unique perspectives. A new approach to this problem stipulates a  trifactor measurement model to analytically disaggregate informants’ unique perspectives of children’s symptoms from a cross-informant consensus rating of their true symptoms (Bauer, Howard et al., 2013). Preliminary results from a new study expand the trifactor model to a three-informant, multi-trait assessment of inattention and hyperactivity/impulsivity symptoms using data drawn from baseline assessments of children enrolled in a randomized controlled trial study of treatments for Attention-Deficit/Hyperactivity Disorder (ADHD).
