A Collaborative Theory-based Intervention to Promote Physical Activity Among Sedentary Parents and Their Children

The intervention will be delivered over a three-month period as a series of four zoom hosted workshops, online content, and a moderated social support group. Zoom workshops will last 45 minutes and will target key constructs from the integrated behavior change model. Main topics of the workshops are autonomy Supportive parenting (Week 1), goal setting and outcome beliefs (Week 3), physical activity norms (Week 5), and encouraging self-efficacy and maintenance (Week 8). Following each workshop, participants will receive links to online content that builds on workshop themes, such as messages, worksheets, and reflection tasks. Throughout the trial, participants will be able to participate in social support chat groups to discuss their progress with other members of the intervention group and intervention facilitators.
