Summary
University students’ physical activity is predicted by intention, behavioral regulation, identity, and habit. Interventions should target both intention formation and sustained engagement for effective physical activity promotion.
Area of Science:
- Behavioral Science
- Health Psychology
- Exercise Science
Background:
- University students often intend to be active but struggle with consistent physical activity.
- Existing theories primarily focus on explicit cognitions like intention, neglecting the full behavioral process.
- The Multi-Process Action Control (M-PAC) model offers a comprehensive framework for understanding intention-to-behavior translation.
Purpose of the Study:
- To apply the Multi-Process Action Control (M-PAC) model to Korean university students.
- To examine the complete process from intention formation to physical activity behavior.
- To assess the predictive utility of the M-PAC framework in this population.
Main Methods:
- 330 university students completed baseline surveys assessing M-PAC constructs.
- 234 participants completed a follow-up survey one month later to measure physical activity.
- Statistical analyses examined the predictive pathways within the M-PAC framework.
Main Results:
- Affective attitude, perceived opportunity, and capability predicted intention (reflective process).
- Intention predicted physical activity via behavioral regulation (regulatory process), identity, and habit (reflexive process).
- Findings align with the M-PAC model's theoretical progression from intention to sustained behavior.
Conclusions:
- Behavioral regulation, identity, and habit are crucial for translating physical activity intention into sustained behavior.
- Interventions should address both the formation of intention and the mechanisms sustaining long-term physical activity.
- The M-PAC model provides a valuable framework for understanding and promoting physical activity in university students.
