Characteristics of peer-based interventions for individuals with neurological conditions: a scoping review

Purpose Peer-based interventions are increasingly popular and cost-effective therapeutic opportunities to support others experiencing similar life circumstances. However, little is known about the similarities and differences among peer-based interventions and their outcomes for people with neurological conditions. This scoping review aims to describe and compare the characteristics of existing peer-based interventions for adults with common neurological conditions. Materials and methods We searched MEDLINE, CINAHL, PsychInfo, and Embase for research on peer-based interventions for individuals with brain injury, Parkinson's, multiple sclerosis, spinal cord injury, and stroke up to June 2019. The search was updated in March 2021. Fifty-three of 2472 articles found were included. Results Characteristics of peer-based intervention for this population vary significantly. They include individual and group-based formats delivered in-person, by telephone, or online. Content varied from structured education to tailored approaches. Participant outcomes included improved health, confidence, and self-management skills; however, these varied based on the intervention model. Conclusion Various peer-based interventions exist, each with its own definition of what it means to be a peer. Research using rigorous methodology is needed to determine the most effective interventions. Clear definitions of each program component are needed to better understand the outcomes and mechanism of action within each intervention.
