Treatment Outcome Measurement Using the Homework Problems Checklist for High School Students With Attention Deficit Hyperactivity Disorder

• In Event: Rasch Modeling in Educational Settings

Abstract

In our randomized controlled trial of the Challenging Horizons Program (CHP) for high school students with ADHD, with 94 students in the control condition, 92 other students received multi-component training in organization and planning, interpersonal skills, and parent homework management. For parent responses to the Homework Problems Checklist (HPC) at baseline and end of the intervention year, we used exploratory factor analyses and Rasch rating scale modeling to evaluate the HPC psychometric and structural properties across time, conditions, and child/family characteristics. The findings on the factor structure and item functioning are clinically significant in treatment outcome research. The approach to pre-post data analyses and presence of DIF items are discussed.
