Mobile Intervention for Veterans With PTSD and Anger
Study Details
Study Description
Brief Summary
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.

Detailed Description
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Mobile Intervention for Reducing Anger (MIRA) Participants in this arm will be provided with a device that has the MIRA application (app) and asked to use the app for a period of 4 weeks. |
Behavioral: Mobile Intervention for Reducing Anger (MIRA)
This is a mobile intervention that uses interpretation bias modification (IBM) techniques to reduce the hostile interpretation bias. Participants will be given a mobile device with the MIRA app and instructed to complete 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.
|
| Active Comparator: Mindfulness Intervention Participants in this arm will be provided with a device that has the Mindfulness application (app) and asked to use the app for a period of 4 weeks. |
Behavioral: Mindfulness Intervention
This is a mobile intervention that uses the Mindful Breathing and Body Scan exercises from the "Mindfulness Coach" app. These audio-guided exercises take approximately 10 minutes each. Participants will be given a mobile device with the Mindfulness app and instructed to complete 5 exercises (i.e., Body Scan or Mindful Breathing) each week for a period of 4 weeks. The app also includes a Nightly Diary to track symptoms, a calendar to program reminders, and a My Progress feature to track use and performance.

Outcome Measures
Primary Outcome Measures
- Feasibility of participant recruitment [Through study completion (approximately 2 years)]
Patient feasibility goal will be met if recruitment is 75% or greater of recruitment expectation.
- Feasibility of treatment retention [Post-treatment assessment visit (approximately one month after enrollment)]
Treatment retention feasibility goal will be met if attrition from MIRA treatment arm is no more than 25%.
- Patient satisfaction: Client Satisfaction Questionnaire [Post-treatment assessment visit (approximately one month after enrollment)]
Patient satisfaction goal will be met if 80% or greater of participants indicate that they are either "very satisfied" or "mostly satisfied" with the MIRA app on item #7 of the Client Satisfaction Questionnaire.
- App utilization [Post-treatment assessment visit (approximately one month after enrollment)]
App utilization goal will be met if MIRA app utilization rates are greater than 50% of expected use.
