Background: Acquired brain injuries are often referred to as the silent epidemic due to a healed external appearance despite internal changes that may lead to depression, anxiety, and dependency. Inpatient peer support groups have been found to help prevent the deterioration of perceived quality of life through psychosocial support, skill transfer, and community integration. Few studies support inpatient rehabilitation support groups with persons with an acquired brain injury, therefore this paper evaluates patient perceived effectiveness of inpatient support groups. Methods: The participants were patients with an acquired brain injury in a rehabilitation hospital. Based on the results of a needs assessment, group modules were designed to target patient needs. Each module consisted of two one-hour group sessions on consecutive days and two or three participants were recruited to participate in each module. The module topics varied based on the needs of the respective participants. Each participant completed a pre and post module questionnaire regarding perceived levels of confidence performing tasks and perceived effectiveness of the module. Data were analyzed and organized into themes. Results: Nine participants were recruited by their primary treating occupational therapist to participate in this program evaluation. Based on the post module questionnaire, all participants ‘agreed’ or ‘strongly agreed’ their perceived levels of confidence increased across all categories as a result of the module. All participants ‘agreed’ or ‘strongly agreed’ the module was effective across all categories. Conclusion: Overall, participant feedback indicates inpatient support groups increase confidence with performing occupations, increase knowledge of recovery, and improve quality of life. Further in-depth investigation on changes in actual levels of confidence performing occupations and actual quality of life over a length of time are needed.
