This pilot study assessed the feasibility of using SwapMyMood, a smartphone application supporting evidence-based strategies for emotion regulation and problem-solving as a supplement to conventional care for military service members and veterans (SM/Vs) experiencing chronic symptoms of mild traumatic brain injury (mTBI) and co-occurring psychological conditions. Eight military SM/Vs were recruited from an intensive outpatient program. Participants were block randomized to an experimental group (conventional care plus use of the SwapMyMood app) or a conventional care only group for six weeks. Conventional care included instruction on problem-solving and emotion regulation strategies using traditional paper manuals and protocols. Effects on the knowledge and use of strategies and related goal attainment were measured. Patient-reported outcomes were measured via several validated problem-solving and emotion regulation scales. No differences were found between groups in goal attainment, global executive function, problem-solving, emotion regulation, and knowledge of how to use the problem-solving and emotion regulation strategies targeted. Experimental group participants rated the application positively, demonstrating feasibility of integration of the app into clinical care. The implementation of SwapMyMood is feasible in a clinical setting. SwapMyMood may be a clinically effective supplemental tool for supporting executive function in SM/Vs with mTBI and co-occurring psychological conditions.
