Problem-Solving Training for Concussion

This study will be a longitudinal randomized two-arm parallel group clinical trial. Participants will be randomized 1:1 to either PST-Concussion or treatment as usual (TAU). Participants assigned to PST-Concussion will receive six, approximately 30-minute telehealth treatment sessions. Assessments will include standard self-report and cognitive measures that will be administered at baseline, post-treatment, and three-month follow-up. The primary objective of this study will be to evaluate the effectiveness of PST-Concussion in reducing psychological distress compared to TAU. Secondary and tertiary objectives will be to evaluate whether PST-Concussion is associated with appreciable change in subjective neurocognitive functioning, objective neurocognitive functioning, psychosocial functioning, and disability and quality of life. Multi-level modeling will be used to evaluate treatment effects at post-treatment and three-month follow-up. A test of non-inferiority will be conducted to evaluate the potential durability of observed treatment effects from post-test to follow-up. A portion of participants assigned to PST-Concussion will also be interviewed at post-treatment or follow-up to gain insight into the practical impact of intervention on psychosocial functioning and quality of life.
