The purpose of the current review is to provide, within the context of social cognitive theory, a current description of behavioral, personal, and environmental factors that motivate or prevent an individual with peripheral artery disease (PAD) from participating in activity. A comprehensive review to explore motivators and barriers to walking in older adults with PAD was performed to help guide development of interventions to increase activity. Several databases were used for the literature review, with inclusion criteria being all study designs with samples of older adults with PAD. From the initial yield of 22 abstracts, and additional hand search, eight publications were used for this review. Social cognitive theory provided a context for understanding barriers and motivators to walking experienced by older adults with PAD. Nurses may contribute to walking self-efficacy with support and motivation. [Journal of Gerontological Nursing, 44(1), 43-50.].
