In Phase I of the proposed research, middle school counselors, psychologists, teachers, middle school students with ADHD and their parents will consult with the intervention developers to modify the after-school treatment protocol for in-school implementation. An intervention protocol will be developed. The intervention will be piloted with ten children in order to identify barriers to implementation. Measures of treatment fidelity, skills acquisition, and satisfaction will be completed. These data will inform additional modifications of the protocol and further improve feasibility/acceptability of the intervention procedures.
