RecruitingBehavioural interventionSKIP for PA Study: Team and Leadership Level Implementation Support for Collaborative CareIn a prior application (MH064372), the investigators' treatment research program (Services for Kids In Primary-care, SKIP) developed and tested a chronic care model-based intervention, called Doctor Office Collaborative Care (DOCC), that was found to be effective in the management of childhood behavior problems and comorbid ADHD. In the "SKIP for PA Study", the investigators propose to conduct a randomized clinical trial to evaluate the effects of team- and practice leadership-level implementation strategies designed to enhance the use and uptake of DOCC in diverse pediatric primary care offices.
