Executive Function and Symptom Reduction in Youth Receiving Home-based Treatment With Collaborative Problem Solving

In this project, the investigators will extend prior results of parent-reported executive function growth and symptom reduction in children receiving home-based treatment with the Collaborative Problem Solving treatment approach (CPS), with a particular focus on examining children who have attention deficit hyperactivity disorder (ADHD). The investigators will examine executive functioning (EF) of children who are receiving CPS, measuring EF with parent-report and objective computer-based tasks, at two timepoints: at the start of treatment and approximately four months later, and will collect symptoms at these plus three additional timepoints: at discharge, 6-months after discharge, and 12-months after discharge.
