The goal of this study is to assess the effects of an exercise-related video on exercise motivation and adherence. Specifically, the researchers are studying whether an exercise-for-mood video increase levels of exercise motivation as compared to an exercise-for-fitness video.
This study is designed to evaluate two interventions for exercise motivation: an exercise-for-mood video and an exercise-for-fitness video. After screening to determine eligibility, participants will complete two virtual study appointments, scheduled 10-20 days apart. In Phase 1, participants will first consent to the study and complete the DASS-21, ASI-3, and EMI-2. Participants will then complete an interview-format 7-day Physical Activity Recall (7-day PAR) about their exercise over the past week. Participants are then randomized to either the Fitness or Mood video by the researcher and are assigned to watch the video while on the Zoom meeting, approximately 11 minutes long. After the video, participants complete two short questionnaires about the credibility and usefulness of the video they watched. Finally, participants are briefed on safe exercise habits and given a goal of moderate exercise 4 times per week. In the Phase 2 appointment, participants complete the EMI-2 and the 7-day PAR about their exercise over the past week. Participants are then debriefed on the intent of the study.

Exercise Motivation
Exercise Motivations Inventory (EMI-2)
Time frame: Assessed at Phase 1 appointment and Phase 2 appointment, scheduled 10-20 days apart.
Exercise adherence
Adherence to an exercise goal of moderate-intensity exercise 4 times per week. Evaluated using the 7-day Physical Activity Recall (7-day PAR).
Time frame: Retrospective accounting of the past 7 days, assessed at Phase 1 appointment and Phase 2 appointment, scheduled 10-20 days apart.
Mood During Exercise
Mood during most typical, intentional physical activity over the past week, evaluated on the Feeling Scale (FS)
Time frame: Assessed at Phase 1 appointment and Phase 2 appointment, scheduled 10-20 days apart
Perceived Exertion during Exercise
Exertion during most typical, intentional physical activity over the past week, evaluated on the Ratings of Perceived Exertion scale (RPE)
Time frame: Assessed at Phase 1 appointment and Phase 2 appointment, scheduled 10-20 days apart
