Motivation for Exercise: A Mood-Based Focus

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.
