Effectiveness of an Educational Intervention to Participation in Physical Activity: A quasi-experimental model-based study

Abstract

Background: The aim of the present study was to assess readiness to become or stay physically active according to the Stages of Change Model.Methods: The present quasi-experimental study was conducted on 100 women working in the healthcare centres of Bandar Abbas, Iran. The sampling method is clustering in type. The subjects were assigned into two groups of intervention and control. The collected data were analysed by SPSS-16 software using descriptive and inferential statistics, including independent-sample t-test, paired-sample t-test and Chi-square test.Results: Before the educational intervention, 19 subjects (0.38%) from the intervention group showed to have regular physical activity (4-5 stages). This number changed to 29 (0.58%) and 25 (0.50%) after three months and six months of intervention. A statistically significant difference was found before the intervention and 3 and 6 months afterwards (P˂.001). In the control group, no statistically significant difference was found between the pre-intervention and post-intervention (three months (P=.351) and six months (P=.687).Conclusion: The educational intervention based on the stages of behaviour change model showed to be effective in promoting the physical activity of employed women. These findings may benefit health education researchers and practitioners who tend to develop innovative theory-based interventions and strategies to increase the level of physical activity in women.
