Summary
Formative process evaluation improved the Together Everyone Achieves More Physical Activity (TEAM-PA) intervention for African American women. This approach enhanced intervention delivery, showing high reach, dose, and fidelity for physical activity promotion.
Area of Science:
- Public Health
- Behavioral Science
- Health Promotion
Background:
- The Together Everyone Achieves More Physical Activity (TEAM-PA) trial evaluated a group-based intervention to increase physical activity in African American women.
- Formative process evaluation was employed to assess and refine intervention implementation, dose, and fidelity.
Purpose of the Study:
- To demonstrate the utility of formative process evaluation in optimizing a physical activity intervention.
- To assess the implementation, dose, and fidelity of the TEAM-PA intervention.
- To identify and implement modifications for group-based physical activity games.
Main Methods:
- The TEAM-PA intervention involved 10-week group sessions led by African American facilitators.
- Intervention components included group feedback, health curriculum, physical activity games, and goal-setting, utilizing a multi-theoretical framework.
- Formative process evaluation monitored reach, dose, and fidelity, incorporating participant feedback for improvements.
Main Results:
- High participant attendance (84.8%) and completion of intervention dose items (93%) were achieved.
- Facilitator and group-level fidelity were adequate, with high participant compliance in wearing FitBits.
- Modifications to physical activity games, based on participant feedback, improved game comprehension from Cohort 1 to Cohort 2.
Conclusions:
- Formative process evaluation successfully supported high levels of intervention reach, dose, and fidelity.
- Strategies for implementing accessible, competitive group-based physical activity games were identified.
- This evaluation approach holds significant potential for enhancing future health interventions.
