Effects of home-based exergaming on child social cognition and subsequent prediction of behavior.

ABSTRACT

The use of exergames may be one viable way to increase child physical activity, but investigation of its effects on motivation over time and prediction of adherence have seen little research attention. The purpose of this study was to compare the effect of two cycling exergame interventions (single-player, multi-player) among children aged 9-12 years on motivational variables (theory of planned behavior) and to explore whether these variables could predict objective assessment of playtime across 6 weeks. Sixty-nine insufficiently active children were recruited through advertisements within the community/schools and randomized to either the single play condition (n = 30) or multi-player condition (n = 39). Exergaming use was recorded objectively via game logs and motivational variables were assessed after a familiarization session, at 2 weeks, and at 4 weeks. Participants played the exergames M = 133.45 (SD = 81.27) minutes in week 1 to M = 77.23 (SD = 84.09) minutes in week 6. The two exergame conditions did not result in differences among theory of planned behavior variables (P > .05). Mean levels of these constructs declined across the first 4 weeks (P < .05), with the exception of injunctive norm. Positive bivariate associations (P < .05) between game play and perceived control (0-6 weeks), and intention (weeks 3-4 and weeks 5-6) were identified, but only affective attitude (assessed at week 2) predicted (P < .05) game play (3-4 weeks) in a multivariate examination of the theory of planned behavior model. The results demonstrate that social cognitive motives wane across time when exposed to repeated exergame play.
