INTRODUCTION: The present study aims at designing and evaluating the effect of new educationalmedia‑based educational intervention on students’ stages of behavior change of physical activity.SUBJECTS AND METHODS: In the present interventional study, 225 students of medical sciencesuniversity were assigned into two experimental and one control groups using proportional stratifiedrandom sampling, where web‑based and software‑based educational interventions were used. Datawere collected using International Physical Activity Questionnaire, Marcus’s stages of change scales,and a self‑made questionnaire including constructs of barriers, benefits, and self‑efficacy. Evaluationwas conducted through pretest and posttest and immediate and 2 and 6 months of follow‑ups afterthe intervention. Data were analyzed by SPSS software using descriptive statistics and Chi‑square,Friedman, one‑way ANOVA, and ANOVA with repeated measure.RESULTS: Based on the results, there was no significant difference between the experimental andcontrol groups before the intervention (P = 0.37); however, immediately and 2 and 6 months afterthe intervention, there was a significant difference between the experimental and control groupsin terms of stages of change (P < 0.001). Furthermore, in the experimental group, the educationalintervention led to improvement of individuals in the stages of change of physical activity. At 6‑monthfollow‑up, 75.4% of the software group and 60.6% of the web group achieved the maintenance stage.CONCLUSION: The results suggest that designing intervention based on people’s level of preparationfor changing behavior and using new educational methods such as web and software were effectiveon individuals’ progress in different stages of change of physical activity behavior and physicalactivity rate.
