General self and physical appearance are scales of the Self-Description Questionnaire-I. Physical self-concept is a scale of the Tennessee Self-Concept Scale: 2. Tension and vigor are scales of the Profile of Mood States - Short Form. Exerc. barriers self-efficacy = Exercise Barriers Self-Efficacy Scale for Children. Voluntary physical activity days/week refers to recalled number of days in the previous week where moderate-to-vigorous physical activity was completed outside of PE and after-school care programming. SD = standard deviation; d = Cohen’s measure of effect size. Treatment group df=144; Control group df= 121.
