The Transtheoretical Model (TTM) has been widely used to understand individuals’ physical activity (PA) correlates and behavior. However, the theory’s application among children in exergaming remains unknown.
Investigate the effects of an exergaming program on children’s TTM-based PA correlates and PA levels.
At pretest and posttest, 212 upper elementary children (mean age = 11.17 years) from the greater Mountain West Region were administered measures regarding stages of change (SOC) for PA behavior, decisional balance for PA behaviors, PA self-efficacy, and self-reported PA levels. Following the pretest, a weekly 30-minute, 18-week Dance Dance Revolution (DDR) program was implemented. Children were classified into 3 SOC groups: progressive children (ie, progressed to a higher SOC stage); stable children (ie, remained at the same SOC stage); and regressive children (ie, regressed to a lower SOC stage).
Progressive children had greater increased PA levels than regressive children (P < .01) from pretest to posttest. Similarly, progressive children had greater increased self-efficacy (P < .05) and decision balance (P < .05) than regressive children.
The findings indicate that progressive children had more improvements on self-efficacy, decisional balance, and PA levels than regressive children over time. Implications of findings are discussed.
