A Video Chat Intervention for Enhancing Self-efficacy for Lifestyle Physical Activity

The intervention group is asked to participate in three (10-minute) video chats during the first three weeks of six weeks of engaging in lifestyle physical activity. Participants in this group will receive information that addresses outcome expectations in week one (e.g. physical, social, and self-evaluative outcomes and intrinsic and extrinsic motives), self-efficacy in week two (e.g. the four efficacy sources: vicarious experiences, mastery experiences, social persuasion, and perceptions of physiological and affective responses to behavior), and self-regulatory strategies in week three (e.g. goal-setting, self-monitoring, and planning) for engaging in lifestyle physical activity.

The time-matched control group is asked to participate in three (10-minute) video chats during the first three weeks of six weeks of engaging in lifestyle physical activity.
