Mobile Intervention for Veterans With PTSD and Anger

Overview

Anger is the mostly commonly reported reintegration concern among combat Veterans, especially those with PTSD. Problematic anger is associated with significant functional impairment. In the current project, the investigators will pilot-test a newly developed mobile app, entitled Mobile Intervention for Reducing Anger (MIRA), among Veterans with PTSD and problematic anger. The project will compare the MIRA app to a contact control condition. The investigators hypothesize that Veterans with PTSD and problematic anger will find the MIRA app acceptable and will be willing to use it to reduce their anger difficulties and improve psychosocial and occupational functioning.

Anger is the mostly commonly reported reintegration concern among combat Veterans, especially those with PTSD. Problematic anger is associated with significant functional impairment. One of the mechanisms associated with problematic anger and aggression is hostile interpretation bias, i.e., a tendency to interpret ambiguous interpersonal situations as hostile. The investigator has previously developed and piloted a computer-based interpretation bias modification intervention that successfully reduces both hostile interpretation bias and anger outcomes. In the current project, the investigators will pilot-test a mobile application version of the existing computer-based intervention, entitled Mobile Intervention for Reducing Anger (MIRA), among Veterans with PTSD and problematic anger. The project will compare the MIRA app to a contact control condition to evaluate the feasibility of recruitment, randomization, and retention procedures. The investigators will also utilize psychophysiological and electronic diary monitoring to determine whether this assessment could be used as an outcome or mechanistic variable in a subsequent randomized clinical trial application focused on evaluating the efficacy of the MIRA intervention.
