The Effect of Transtheoretical Model-Based Education on Promoting Physical Activity among Employees of Abumusa Island, Iran

Promoting physical activity is one of the most effective strategies for reducing the risk of some chronic and non-communicable diseases. One of the theoretical approaches to the promotion of physical activity is the transtheoretical model. The aim of this study was to determine the effect of transtheoretical model-based education on promoting physical activity among employees of Abu Musa Island, Iran.
In this quasi-experimental study, employees were divided into intervention and control groups and assessed before, and 3 and 6 months after the educational intervention. Studied variables included demographic data, stages of change in physical activity, perceived benefits and barriers, and self-efficacy regarding physical activity. The transtheoretical model-based intervention included lectures, group discussions, poster, pamphlet, and video. Data were analyzed using SPSS software.
Findings: Before the educational intervention, intervention and control groups were not significantly different in terms of physical activity. In the intervention group, physical activity increased significantly 3 months after the intervention (P 0.05).
This study showed that transtheoretical model based-intervention can be effective on promoting physical activity 3 months after the intervention, but these changes may decrease with further passage of time. Hence, the use of this model for improvement of physical activity should be continuous until all individuals reach the maintenance stage.
