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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Exercise for Mood video | Experimental | The Exercise for Mood intervention is an approximately 11-minute video shown to participants which presents a mood-based motivational frame for exercise and physical activity. Video content focuses on discussions related to the immediate mood benefits from exercise, longer-term cognitive and mental health benefits of exercise, effects of positive affect during exercise, and mood-centered strategies for engaging in regular physical activity, including exercising in diverse locations, exercising with friends, and exercising with music or audiobooks. |
