Brief 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.

Outcome Measures

Primary Outcomes (1)

• Change in Self-efficacy for Lifestyle Physical Activity (SELPA)

  The SELPA is a 6-item questionnaire that assesses beliefs in one's ability to engage in physical activity of one's own choosing to meet the physical activity guidelines. The SELPA is a modified version of the Lifestyle Efficacy Scale (McAuley, Hall, Motl, Wojcicki, White, Hu, \& Doerksen, 2009). In this study, participants are asked to assess their confidence in their ability to accumulate five or more times per week at a moderate intensity, for at least 30 minutes for six weeks. Each question is based on a confidence scale ranging from 0% (not confident at all) to 100% (highly confident). The SELPA composite score is calculated by summing and averaging the six items, with higher scores representing greater self-efficacy for lifestyle physical activity.

  Assessed at baseline, at week 2, 3, and 4, as well as end of study (beginning of week 8)

Secondary Outcomes (15)

• Lifestyle Physical Activity (subjective)

  Assessed at baseline and at 6-week follow-up

• Lifestyle Physical Activity (objective)

  Assessed for entirety of 7-week study

• Positive and Negative Feeling States

  Assessed at week 1 (pre/post-treadmill assessment)

• Anticipated Negative Affect

  Assessed at week 1 (pre/post-treadmill assessment)

• Forecasted Pleasure

  Assessed at week 1 (pre/post-treadmill assessment)

Other Outcomes (1)

• Overall Enjoyment with Physical Activity

  Assessed at 6-week follow-up

Study Arms (2)

Efficacy for Lifestyle PA

EXPERIMENTAL

Three brief (10-minute) video chats during first three weeks of six weeks of lifestyle physical activity engagement providing information relative to outcome expectations (week 1), self-efficacy (week 2), and self-regulatory strategies (week 3) to enhance self-efficacy for lifestyle physical activity.

Behavioral: Efficacy for Lifestyle PA

Efficacy for Work-life Balance

ACTIVE COMPARATOR

Three brief (10-minute) video chats during first three weeks of six weeks of lifestyle physical activity engagement providing information relative to outcome expectations (week 1), self-efficacy (week 2), and self-regulatory strategies (week 3) to enhance self-efficacy for work-life balance.

Behavioral: Efficacy for Work-life Balance

Interventions

Efficacy for Lifestyle PA BEHAVIORAL

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.

Efficacy for Work-life Balance BEHAVIORAL

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.
