Official title
A Randomized Controlled Trial of the Mobile Anger Reduction Intervention for Veterans
Overview
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.
Detailed description
Difficulty controlling anger is the most commonly reported reintegration concern among combat Veterans, especially those with a diagnosis of posttraumatic stress disorder (PTSD). In Veterans, problematic anger is associated with numerous negative psychosocial outcomes, including poor functional outcomes (both social and occupational), family discord, aggression, road rage, and suicide risk. Anger can also impede successful outcomes from PTSD treatment. Given the high prevalence of anger problems among Veterans with PTSD and the associated functional impairments, there is a clear need to develop innovative and effective anger interventions to improve functional outcomes. Use of mobile health (mHealth) technology could provide a low-cost method to increase the reach of anger management treatments to this high-need group of Veterans.
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. By reducing hostile interpretation bias, the investigators can reduce problematic anger and aggression and improve functional outcomes. A mobile application that uses evidence-based interpretation bias modification techniques to reduce hostile interpretation bias and anger outcomes has been developed and piloted. The goal of this project is to evaluate the efficacy of this mobile application among Veterans with PTSD.
A randomized controlled trial (RCT) will be conducted, in which 150 Veterans with PTSD and problematic anger will be randomized to either the Mobile Anger Reduction Intervention (MARI) or a health education condition (HED). The central hypothesis is that participants in the MARI condition will experience greater anger reductions and functional improvements relative to the HED condition.
The proposed research project will address the following Specific Aims: Aim 1: To evaluate the efficacy of MARI on anger outcomes (e.g., hostile interpretation bias, problematic anger) measured at post-treatment, 3-months, and 6-months post treatment; Aim 2: To evaluate the efficacy of MARI on functional improvements (i.e., psychosocial functioning, quality of life) and self-harm measured at post-treatment, 3-months, and 6-months post treatment; and Exploratory Aim: To explore whether changes in hostile interpretation bias (proposed treatment mechanism) mediate functional improvements.
Interventions
- Behavioral Mobile Anger Reduction Intervention (MARI)
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. - Behavioral Health Education Condition (HED)
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.
Primary outcome measures
- number of participants below the clinical cut off for problematic anger [Time frame: Post-treatment (approx. one month after baseline assessment)]
- number of participants below the clinical cut off for problematic anger [Time frame: 6-month follow-up]
- number of participants below the clinical cut off for problematic anger [Time frame: 3-month follow-up]
- number of participants with decreased hostile interpretation bias scores [Time frame: from baseline to post-treatment assessments (approx. one month after baseline assessment)]
- number of participants with decreased hostile interpretation bias scores [Time frame: from baseline to 3-month follow-up]
- number of participants with decreased hostile interpretation bias scores [Time frame: from baseline to 6-month follow-up]
Secondary outcome measures (9)
