Using Acceptance and Commitment Training to Promote Rehabilitation and Engagement in Values-Centered Living in Veterans Adapting to Inflammatory Bowel Disease and Mental Health Challenges (RECLAIM)

Nearly 80,000 Veterans have inflammatory bowel disease (Crohn's disease and ulcerative colitis; IBD). IBD is characterized by chronic inflammation of the gastrointestinal tract leading to significant pain, elimination difficulties, and functional impairment. Compounding these difficulties, nearly 50% of Veterans with IBD have comorbid depression, anxiety, and/or posttraumatic stress disorder. These comorbid conditions worsen IBD symptoms through the brain-gut axis, and lead to dramatic deficits in quality of life (QOL) and psychosocial functioning. Yet, less than 20% of patients with IBD and mental health conditions receive psychotherapy and 25-50% of psychotherapy patients drop out before clinically indicated. VA's integrated behavioral healthcare in primary and specialty care clinics increases therapy engagement and adherence, improving Veteran health and functioning. Despite this, psychogastroenterology services are underdeveloped in VA gastroenterology (GI) clinics. Moreover, no evidence-based psychotherapies have been tested in Veterans with comorbid IBD and mental health problems. It is essential to develop evidence-based psychotherapies for integrated use in GI clinics to practically increase access to care and improve the functioning and QOL of Veterans with GI conditions. Acceptance and commitment therapy (ACT) is a transdiagnostic psychotherapy that improves psychosocial functioning and QOL in patients with a variety of chronic and mental health conditions. ACT is flexibly delivered in various treatment formats, allowing providers to utilize methods that match the needs of specific populations and clinical settings. One-day ACT workshops improve access and retention while effectively and efficiently improving the psychosocial functioning of Veterans with various chronic health conditions. A pilot study of 1-day ACT for patients with IBD suggested preliminary feasibility, acceptability, and effectiveness in improving QOL. However, this pilot did not target Veterans or those with mental health conditions and was not delivered as an integrated part of GI care. This is a concern, as 1-day ACT is efficient and effective, yet is rarely used in routine clinical practice. Adapting 1-day ACT for integrated use in VA GI clinics will increase Veteran access to brief, evidence-based, rehabilitative treatment. This study aims to improve the psychosocial functioning and QOL of Veterans with comorbid IBD and mental health conditions by adapting and testing a 1-day, integrated ACT intervention, coined RECLAIM. The aims of this study are to: 1) Characterize the ACT-specific coping factors associated with psychosocial functioning and QOL in Veterans with IBD using survey and interview data to inform intervention adaptation; 2) Adapt a 1-day ACT intervention for Veterans with IBD and comorbid depressive, anxiety, and trauma disorders for integrated use in GI clinics. Pilot intervention (RECLAIM) with 10 Veterans and refine; 3) Test the feasibility and acceptability of RECLAIM with 40 Veterans with IBD and comorbid depressive, anxiety, and trauma disorders using a convergent mixed-methods design.
