Description

Difficulty controlling anger is the most commonly reported reintegration concern among combat Veterans, especially those with a diagnosis of posttraumatic stress disorder (PTSD). Problematic anger is associated with significant functional impairment. In the current project, the investigators will compare the Mobile Anger Reduction Intervention (MARI) with a health education mobile intervention (HED) among Veterans with PTSD and problematic anger. Participants will be randomized to the MARI or HED condition. The hypothesis is that participants in the MARI condition will experience greater anger reductions and functional improvements relative to the HED condition.

Interventions

Mobile Anger Reduction Intervention (MARI) (Behavioral)
This is a mobile intervention that uses interpretation bias modification (IBM) techniques to reduce the hostile interpretation bias. Participants will download the MARI app and be instructed to complete at least 5 treatment sessions each week for a period of 4 weeks. Each session takes approximately 10 minutes. The app also includes a Nightly Diary to track symptoms, a calendar to program session reminders, and a My Progress feature to track use and performance.
Health Education Condition (HED) (Behavioral)
This is a mobile application that delivers videos with psychoeducation about healthy habits and selfcare for general wellness. Participants will download the HED app and be instructed to use it at least 5 times a week for a period of 4 weeks.
