The authors examined whether purposeful walking with peers at least once a week contributes to better behavioral and health outcomes in older adults than primarily walking alone. The authors used a longitudinal cohort design and recruited participants aged 60 years and older (N = 136) at the start of a 16-week walking intervention. Participants who walked on average at least once a week in the final 8 weeks of the intervention were included in the analysis (N = 79; 66 females, Mage [SD] = 77.73 [6.91]). The authors found that autonomous motivation, walking self-efficacy, functional capacity, body fat, and physical activity improved more in the walking with peers group compared with the walking alone group, after controlling for whether participants lived alone/with others and their health status. The results extend current literature by providing longitudinal evidence for the added benefits of regular peer-accompanied walking in older adults and highlight the importance of investing in peer-supported interventions.
