What this Trial Is About

More than 1 million U.S. youth sustain a concussion each year, and up to 30% report persistent post-concussive symptoms (PPCS) lasting 1 month or more. PPCS can interfere with normal adolescent development, resulting in issues with socioemotional dysfunction and even school failure. However, few evidence based treatments are available for youth with PPCS. The investigators conducted extensive work adapting a collaborative care framework for youth with PPCS, combining concussion-focused cognitive behavioral therapy (cf-CBT), parent skills training (PST) and care management (CM) to create a wraparound treatment for youth with PPCS that can be delivered either in-person or virtually. They completed an R01-funded randomized controlled trial with this approach, finding effectiveness for youth with PPCS, with improvements in concussive symptoms and quality of life at one year, and 60% of participants completing the intervention entirely virtually. Of note, this intervention is unique in that two of the components are focused on parents or parents and youth together (PST, CM), and only one of the components (cf-CBT) is solely youth focused. The investigators now propose to optimize and refine this approach, conducting a high efficiency MOST (multiphase optimization strategy) trial to assess the contribution of each of the three components (cf-CBT, PST and CM) to effectiveness, thereby enabling streamlining of the intervention to only include active components. The analysis will be factorial, with three intervention components and two levels of each (present or absent), resulting in 8 treatment pathways. The benefit of the MOST approach is that it combines all youth who receive a component, allowing assessment of all treatment components with only a modest sample size. The study will recruit 374 youth with PPCS, randomizing them to one of 8 treatment groups. Youth and/or parents will attend treatment sessions via video conferencing software over three months, and complete surveys regarding primary outcomes (concussive symptoms and health-related quality of life) and secondary outcomes (sleep, pain, mood and parental distress) at 6 weeks, and 3, 6 and 12 months. Potential mediators and moderators will also be assessed to allow for future tailoring and refinement. At the completion of this study, the investigators will have generated a completely optimized and refined intervention for youth with PPCS ready for large scale implementation and dissemination.
