Videoconferencing is a novel method for overcoming time and transportation barriers to leisure-time physical activity (LTPA) interventions. This study examined the feasibility of a group videoconference intervention on LTPA self-regulatory skills training in a sample of nine adults with spinal cord injury (SCI). Session implementation checklists and self-report surveys were administered during four weekly sessions to assess intervention management, group processes, intervention resources, and initial efficacy. Attendance rate was high (91.7%), and the average weekly session duration was 79.6 min. Participants reported high ratings of group cohesion, facilitator collaboration, session content comprehension, and ease in operating the videoconference platform. Knowledge sharing among the group ranged from 18 to 58 exchanges per session, demonstrating learning and group cohesion. LTPA frequency increased among 44% of participants, and 22% of participants achieved the SCI-specific aerobic guidelines. Overall, group videoconferencing holds promise for LTPA support among adults with SCI. Long-term research is warranted to test LTPA self-regulatory and behavioral effects.
