The purpose of this study is development of the Integrative Pediatric FPA ADHD Care (IPFAC) Model. The IPFAC is intended to increase access to evidence-based behavioral parent training (BPT) for school-age children diagnosed with attention-deficit/hyperactivity disorder(ADHD) who are diagnosed with ADHD and served in the ADHD Clinic at NYU Bellevue's Department of Developmental and Behavioral Pediatrics.

The specific aims of this study are to: 1) Develop the IPFAC model (Phase I); 2) Assess and determine facilitators and barriers to fidelity, assess feasibility of data acquisition, determine preliminary efficacy, and refine the IPFAC model through a small-scale implementation study and Plan-Do-Study-Act methods (Phase II), and, 3) Evaluate the revised IPFAC model in a small-scale study using state-of-the-art single-case study design methods/analyses to test "treatment mechanisms" in a sample of newly diagnosed youth with ADHD (Phase III) and finalize the IPFAC procedural manual.
