5. Conclusion
This multi-behavioral intervention evidenced greater PA levels and self-efficacy for exercise, alongside a decrease in body weight and BMI, among Philadelphia University students. Consequently, this intervention may be implemented as a principal program or in combination with other programs as a means of improving Jordanian university students’ healthy lifestyles. The intervention comprised of multiple behavioral change strategies, with no firm conclusions establishing which intervention elements were responsible for the most success, or whether all elements of the intervention are required at the delivered intensity in order to generate an equivalent magnitude of change. Therefore, further research is necessary to establish the ‘amount’ of intervention required to generate PA behavioral change. This study’s participants were contacted through follow-up appointments only at 6 months, therefore it is not understood whether such behavioral changes are sustained over the long term. Moreover, the intervention’s cost-effectiveness must be ascertained to determine the intervention’s applicability.
