2. Can group differences among behavioural, and health-related fitness outcomes be explained through a mediation model? Hypothesis: The covariance of the assigned conditions (habit formation, planning + education, education control) on child physical activity will be explained by parental support habit, and through the use of consistency and cues regulation strategies (i.e., manipulation check). In turn, the covariance between support habit and health-related outcomes will be explained by physical activity among conditions. The habit formation condition will not affect parental support intentions or underlying outcome expectations (benefits of physical activity) for support of child physical activity because its effect on behavior is to tie initial intentions to behavioural action or to work independent of goals and intentions.
