Summary

The purpose of this study is to evaluate the efficacy of three, brief (10-minute) theory-guided video chats for increasing self-efficacy for lifestyle physical activity versus a time-matched video chat comparison group designed to increase self-efficacy for work-life balance. Participants will include individuals who are low-active, full-time (\>35 hours/week) working adults.

Detailed description

Eligible participants will complete three brief (10-minute) video chats to promote self-efficacy during the first three weeks of engaging in lifestyle physical activity. Randomization will place participants into one of two groups: (1) Social Cognitive Theory-guided video chat or (2) time-matched video chat comparison group. Video chats will be delivered via the Google Duo smartphone app. Baseline and follow-up assessments will consist of psycho-social questionnaires assessing constructs of the Social Cognitive Theory, affect, stress, and work-life balance. Physiological measures including heart rate will be assessed during a baseline treadmill assessment (to be completed in lab). All participants, regardless of group, will be asked to wear an activity tracker for the entirety of the study for assessing lifestyle physical activity. The comparison group will be asked to complete all baseline and follow-up assessments but will not receive information relative to lifestyle physical activity. The baseline assessments will take place with an academic research laboratory and weeks 2-7 will take place off outside of the lab.

Interventions

Type	Name	Description
BEHAVIORAL	Efficacy for Lifestyle PA	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.
BEHAVIORAL	Efficacy for Work-life Balance	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. 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 work-life balance.
