[BDSP. Notice produite par INIST-CNRS ad7UR0x3. Diffusion soumise à autorisation]. We examined predictors of leisure-time physical activity intention and behaviour in children, and the potential direct and moderating effects of gender and ethnicity. Participants were 364 (230 Asian ; 134 Caucasian) 9-11-year-old children who completed measures of the theory of planned behaviour (TPB) and physical activity behaviour (Physical Activity Questionnaire for Children) across three, 3-month intervals (i.e., two prediction time-periods) in Canada. The TPB explained 35-50% of the variance in physical activity behaviour and 74-76% of the variance in intention using structural equation modelling. An autoregressive longitudinal path model showed that the TPB predicted changes in physical activity and physical activity predicted changes in TPB constructs (p<. overall intention and perceived behavioural control were significant contributors to the direct prediction of behaviour subjective norm predictors intention. gender did not show a robust relationship with physical activity or but effect ethnicity on was mediated through less active than caucasians finally moderate tpb relations these data suggest that childhood may be formative stage for development cognitions promoting in children require normative control-based intervention.>
