Abstract
The purpose of this study was to evaluate the efficacy of the i-PAP, an internet-based Physical Activity Program, in promoting physical activity, as well as to assess the effectiveness of i-PAP functions and e-mail tip sheets in promoting positive attitudes toward regular physical activity. This study was designed to test the efficacy of the i-PAP over a 14-week, in-semester period among 81 college students who had been allocated to an intervention group (n=52) or a no-intervention group (n=29). In repeated measures ANOVA, the intervention group exhibited a significant increase in energy expenditure, compared to the no-intervention group. In factor and path analyses, goal-setting and scheduling the latter of which involved the individual setting dates and times for regular physical activity were critical functions in promoting physical activity. The i-PAP showed strong effectiveness in promoting physical activity, as expected. In particular, goal-setting and scheduling seemed to have positive effects on attitudes toward physical activity.
