Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to compare an adaptation of Behavioral Activation, a behavioral intervention, to Relapse Prevention treatment, another behavioral intervention, in a sample of U.S. military veterans with co-occurring alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD).

The primary aims of this study are to:

1. Adapt Behavioral Activation to treat veterans with AUD/PTSD,
2. Evaluate the feasibility, acceptability, and preliminary effects of Behavioral Activation for AUD/PTSD, and
3. Explore geospatial analysis as a new method for measuring AUD/PTSD recovery.

Participants will complete self-report and interview measures immediately before and immediately after treatment. Participants will also be asked to participate in passive geospatial assessment for 14-day periods immediately before and immediately after treatment. Participants will be randomized to treatment condition, which involves 8 sessions of either Behavioral Activation or Relapse Prevention, delivered individually by a trained study therapist.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Alcohol use disorder (AUD) frequently co-occurs with posttraumatic stress disorder (PTSD) among U.S. military veterans. Compared to veterans with AUD only, veterans with AUD/PTSD have greater symptom severity, more psychosocial functioning difficulties, and higher risk of suicide. Many people with AUD/PTSD perform behaviors aimed at avoiding unpleasant emotions (e.g., drinking to avoid trauma-related nightmares, skipping social events to avoid anxiety-provoking crowds). These "avoidance behaviors" provide temporary relief from unpleasant emotions, but they maintain AUD/PTSD and interfere with long-term functioning. Although treatments for AUD/PTSD exist, they emphasize symptom reduction (not functional improvement) and have dropout rates as high as 50%. Originally developed to treat depression, Behavioral Activation (BA) is an intervention that increases daily participation in rewarding, alcohol-free activities relevant to patients' social, vocational, and health-related values. Randomized controlled trials (RCTs) adapting BA for other disorders have shown that BA is efficacious for adults with alcohol/drug use disorders and acceptable to veterans with PTSD, but BA has not been used to treat co-occurring AUD/PTSD. Additionally, because RCTs of AUD/PTSD treatments typically emphasize significant mean group differences in AUD/PTSD outcomes, less is known about the degree to which these treatments yield clinically significant improvements at the individual level. Individual-level improvements in AUD/PTSD should be evident not only in subjective clinical assessments, but also in objective measures of geospatial activity. Specifically, patients' daily geospatial activity is likely to change as they decrease their avoidance behaviors and increase their engagement in various social, vocational, and health-promoting activities. Advances in geospatial methods, coupled with discreet and portable global positioning system (GPS) trackers, have made it possible to objectively measure people's spatial movement within their communities. Yet although geospatial methods have been used to identify social determinants of alcohol use, they have not been used to measure response to AUD or AUD/PTSD treatment. As the long-term objectives of this work are to identify a more acceptable AUD/PTSD treatment option and improve the measurement of AUD/PTSD recovery, this R34 project will address the following specific aims: (1) adapt BA for use with veterans with AUD/PTSD; (2) evaluate the feasibility, acceptability, and preliminary effects of BA, relative to Relapse Prevention, for veterans with AUD/PTSD in a pilot RCT; and (3) explore geospatial analysis of GPS-collected data as a new approach to measuring AUD/PTSD treatment response. This study will advance research and practice by piloting a novel application of BA and a novel measure of AUD/PTSD recovery. This project aligns with the National Institute on Alcohol Abuse and Alcoholism's special interest in investigating treatments for patients with AUD and co-occurring disorders, dimensions of functioning and well-being associated with recovery, and innovative methods for evaluating AUD treatment and recovery.

Outcome Assessors

Outcomes assessors will be blind to treatment condition. The participant, study therapist, and PI (providing clinical consultation and evaluating therapist fidelity to treatment protocol) will not be blinded to participants' assigned treatment condition.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Behavioral Activation (BA)

Individual psychotherapy

Group Type EXPERIMENTAL

Behavioral Activation (BA)

Intervention Type BEHAVIORAL

BA reduces alcohol use and posttraumatic stress symptoms and increases psychosocial functioning via psychoeducation, activity monitoring, values clarification, and activity scheduling.

Relapse Prevention (RP)

Individual psychotherapy

Group Type ACTIVE_COMPARATOR

Relapse Prevention (RP)

Intervention Type BEHAVIORAL

RP reduces alcohol use via increasing awareness and avoidance of high-risk situations, enhancing drink refusal skills, improving assertiveness, and other strategies.
