The purpose of this study was to assess the effectiveness of text messaging with pedometer intervention for increasing physical activity of college students. Using a two-group prospective randomized intervention-based design, the researchers gave 201 college students pedometers and divided them into intervention and control groups. The intervention group received motivational text messages for 10 weeks; the control group received none. Pre- and post-measures included height, weight, and waist circumference. Daily step counts were collected at three intervals. Total standardized steps were not significantly different between groups. Steps for resident students were higher than for commuter students, suggesting that residents had higher levels of physical activity (p = 0.003). Text messaging was not effective in increasing physical activity when used with pedometers.
