Summary
The theory of planned behavior (TPB) predicts mental health professionals' stage of change for physical activity promotion. Past behavior significantly influenced these predictions, highlighting its importance.
Area of Science:
- Health Psychology
- Behavioral Science
- Public Health
Background:
- Physical activity promotion is crucial for overall health.
- Mental health professionals play a role in encouraging healthy behaviors.
- Understanding factors influencing health behavior change is essential for effective interventions.
Purpose of the Study:
- To evaluate the predictive ability of the theory of planned behavior (TPB) for physical activity promotion stages among mental health professionals.
- To identify key determinants of intention and stage of change in this professional group.
Main Methods:
- A six-month prospective questionnaire study was conducted.
- 394 mental health professionals participated.
- Structural equation modeling was used to analyze attitudes, subjective norms, intentions, perceived behavioral control, and stage of change.
Main Results:
- The TPB model explained 27% of the variance in the stage of promoting physical activity.
- Sixty-one percent of the variance in intention to promote physical activity was explained.
- Past behavior was the strongest predictor of both intention and stage of change, improving prediction by 11% and 6% respectively.
Conclusions:
- TPB variables effectively predict the stage of change for physical activity promotion in a healthcare setting.
- Past behavior significantly influences future promotion efforts.
- The stage model's utility may be limited by uneven stage distribution among professionals.
