RecruitingBehavioural interventionImproving Health for Older Adults With Pain Through EngagementThe goal of this project is to conduct a randomized, hybrid type 1 effectiveness-implementation trial (N=200) to evaluate the effectiveness and implementation of a 10-week mind-body and walking program (GetActive+) vs treatment as usual (TAU). The investigators will test for improvements in self-reported, performance-based (i.e., six-minute walk test), and objective (i.e., step-count) physical function, emotional function, as well as feasibility, acceptability and implementation markers. Participants will complete measures at baseline (0 weeks), post-intervention (1 week after intervention completion), and 6-month follow-up. This study will receive support from and inclusion in the HEAL Initiative (https://heal.nih.gov/).
