Effect of the SNS-Based Physical Activity-Related Psychological Intervention on Physical Activity and Psychological Constructs among Inactive University Students

Abstract

Background/ObjectiveThe current study investigated the effects of the physical activity-related psychological intervention via social network service (SNS) on physical activity and psychological constructs in inactive university students. MethodThirty inactive university students participated in the 12-week intervention and received the physical activity-related psychological strategy via SNS. The physical activity levels, stages of physical activity, self-efficacy, pros, and cons were measured at the three time points (baseline, after 6 weeks, and after 12 weeks). Data analyses included frequency analysis, McNemar chi-square (χ2) test, and a repeated measures ANOVA were conducted. ResultsResults indicated that the number of inactive university students gradually decreased across the three different time points, and that a total physical activity of inactive university students significantly increased over the 12-week intervention. In addition, pros and self-efficacy significantly increased but cons gradually decreased over the intervention. ConclusionsThe current study suggests that the SNS-based physical activity-related psychological strategies have positive effects on promoting physical activity and its related psychological constructs for inactive university students.
