ACTIVE: Activity Therapy to Increase Veteran Engagement

Objectives: Nearly 400,000 Veterans have been diagnosed with traumatic brain injury (TBI) since 2000, representing up to 22% of combat casualties. Depression is one of the most prevalent and serious of TBI sequelae. Post-TBI depression adversely affects rehabilitation, treatment adherence, community reintegration (CR), quality of life (QOL), social relationships, and caregiver burden. Yet, post-TBI depression remains under-assessed, undertreated, and under-studied. No clinical guidelines for post-TBI depression treatment exist, and current treatment is largely based on expert opinion rather than evidence from controlled clinical trials.

A promising therapeutic approach to post-TBI depression is Behavioral Activation (BA), a brief and pragmatic treatment rigorously tested since the 1970s in clinical trials for depression in diverse clinical populations. BA helps individuals set goals, create plans, and engage in activities that improve mood and maintain social connectedness - making it well-suited to treating depression in a TBI population that struggles to set goals and is prone to social isolation. BA can accommodate hallmark deficits of TBI such as deficits in memory, organization, planning, initiation, emotion regulation, and interpersonal functioning. It can be delivered by professionals routinely available in VA outpatient rehabilitation services (e.g., occupational therapists, nurses, psychologists, social workers) and, therefore, can be deployed in rehabilitation settings.

The proposed research will assess the feasibility of a BA protocol adapted for post-TBI depression in an outpatient VA rehabilitation setting. Specific study objectives are to: (1) assess BA's acceptability to Veterans and staff and other feasibility indices, (2) provide preliminary evidence of participant response in the outcomes of depressive symptoms, CR, and QOL at the 3-month follow-up interview, (3) develop the BA protocol and manual to be tested in a larger randomized controlled trial (RCT) in the future, and (4) explore engagement in activity as the mechanism that underlies BA intervention effects on outcomes.

Research Design: This feasibility study includes a pilot randomized controlled trail to examine participant response.

Methodology: This feasibility study will enroll at least 40 male and female Veterans receiving care at a VAMC Rehabilitation Medicine Service and meeting study criteria for TBI and depression. Veterans will be randomly assigned to BA plus treatment as usual (TAU) or control (TAU). The BA program consists of six sessions delivered over 3 months at the VA (or the Veteran's home, as preferred by Veteran) by an occupational therapist (OT). All Veterans are interviewed at baseline before randomization and 3 months later by a blinded interviewer. Both interviews assess Veterans' depressive symptoms, CR, and QOL, using standardized instruments. Feasibility will be assessed in six domains: acceptability to Veterans and clinic staff; process (recruitment, refusal, and retention rates; study completion; eligibility criteria; and number of sessions attended); practicality (resources and constraints imposed by the setting); safety; participant comprehension of interviews and the intervention; and research burden (length of interviews, participant fatigue, and emotional distress). After the follow-up interview, phone interviews with BA participants and with clinic staff will be conducted to capture acceptability and their experience with BA. These qualitative and quantitative methods are designed to test the feasibility of a future RCT, identify the barriers and facilitators to implementation of BA in the rehabilitation setting, and describe Veterans' experiences with BA.

Impact/Significance: This study and line of research has the potential to advance knowledge by identifying a feasible and efficacious approach to preventing and/or mitigating depression among Veterans with TBI, a clinical population at high risk for depression and its sequelae. Findings will be used to inform the development of a future RCT powered to test BA's efficacy in a larger sample of Veterans with post-TBI depression.
