Previous research studies examining parental influences on children’s physical activity (PA) have focused primarily on parents’ own PA behavior, as well as their PA-related beliefs and socially supportive behaviors. The present study, although aligned with this mainstream parental influence research, was grounded in a broader child development perspective to examine the influence of parenting style on children’s PA beliefs and quality of parent–child communication.Self-report questionnaires were administered to 173 children ranging in age from 9 to 12 years to assess their perceptions of parenting style, parent–child communication patterns, as well as their own perceptions of fitness competence, value, and goal orientation.Children’s constellation of beliefs and attitudes regarding PA as well as their perceptions of the parent–child communication process did vary as a function of the type of parenting style they perceived their parents to use. High challenge parenting style was linked to higher perceived fitness competence and value on the part of the children. High support parenting style was linked to more positive perceived parent–child communication patterns.Parenting style may be a critical underlying family process variable that impacts children’s development of a positive constellation of beliefs about PA. Future work is needed to link parenting style and children’s PA beliefs to their PA behavior.
