 Objectives: The study purpose is to evaluate the feasibility of a randomized controlled trial RCT protocol designed to evaluate the effectiveness of an education and skills workshop plus a 3-month outdoor walking group GO-OUT program compared to the workshop alone in improving outdoor walking activity. Specific objectives are to characterize participants; determine the feasibility of recruitment; estimate withdrawal rates and the safety and feasibility of the study protocol; obtain preliminary effect sizes; identify the optimal measure of outdoor walking activity based on validity, reliability, effect size and data completeness; and identify participants and intervention facilitators perceptions of the challenges and benefits of the intervention and evaluation tools.
