Designing and evaluation of E-health educational intervention on students’ physical activity: an application of Pender’s health promotion model

BACKGROUND: The present study was conducted to design and evaluate the software and web-based curriculum based on Pender Model in order to promote students’ physical activity. METHODS: This is a quasi-experimental study conducted on 225 eligible students who were randomly divided into two groups of web and software-based intervention and control. The sample size of the study was selected using stratified sampling method. The evaluation was done with pre-test and post-test and follow-up, which were performed immediately two and six months following the intervention. The data were analyzed employing statistical software SPSS using descriptive statistics, chi-square, one way ANOVA, and repeated measures ANOVA. RESULTS: The obtained results revealed that the level of physical activity after the intervention in the web and software groups significantly increased compared to the control group (p < 0.001). Moreover, the mean score of Pender model constructs, immediately two and six months after the intervention, was significantly different in the web and software groups (p < 0.001). CONCLUSION: Our results indicated that, providing tailored message based on health promotion model’s constructs has a positive effect on promoting physical activity of students.
