This study explored parents' intention to use social control following a hypothetical lapse in their child's activity. Also examined was the role of parent and child activity as predictors of parental social control use. Parents (N = 140) were presented with 2 activity lapse vignettes (health consequences and no health consequences) and reported their intention to use social control after reading each. Results revealed greater parental intention to use social control following the health-consequences lapse. Active parents reported greater intentions of using positive and collaborative social control tactics. Findings provide preliminary evidence that parents, especially those who are active, may attempt to regulate their child's activity following a failure to engage in a health-enhancing behavior (i.e., lapse in physical activity).
