Examining the Efficacy of the Man Therapy Platform in Reducing Problematic Anger Among Military Service Members With and Without a TBI History

The goal of this randomized controlled trial is to determine if an interactive digital solution, Man Therapy, reduces indices of problematic anger in male military service members who screen positive for problematic anger. The man questions this study aims to answer are: * Does Man Therapy reduce indices of problematic anger? * Does Man Therapy reduce psychosocial correlates of anger? Researchers will also examine if the effects of those aims differ based on a participant's history of a mild TBI, the mechanism of a primary mild TBI, and/or the number of mild TBIs. Researchers will compare Man Therapy to a waitlist control. This will help determine if Man Therapy works better than no treatment. Participants will: * Complete a baseline survey * Be randomized to intervention or waitlist control * If randomized to intervention, participants will receive the intervention and complete a survey immediately after the intervention and at 1-, and 3-months following the intervention * If randomized to waitlist control, participants complete surveys at 1-, and 3-months and have the opportunity to complete the intervention following the 3-month survey

Inclusion Criteria: * Military service member * Identify as male * Aged 18+ years * Positive problematic anger screen (DAR-3 \>8) * Ability to read, write, and speak English * Currently located in the U.S. Exclusion Criteria: * Active psychosis or acute mania necessitating clinical intervention * Acute thoughts of self- or other-harm necessitating imminent clinical intervention (e.g., hospitalization) * Expect to be deployed outside of the continental United States in the next 3 months * Unable to provide informed consent
