The advent of the 21st Century brought a new interest in promoting Positive Youth Development and a renewed emphasis on understanding transactional relations between parenting and adolescent development. The present study examined conventional parent-driven pathways, which describe the putative role of parents in the formation of positive characteristics in children, as well as the prospect of child-driven effects, which describe how parents respond to evidence of Positive Youth Development by potentially increasing support and reducing psychological control. We tested these pathways in a sample of 458 Lithuanian adolescents (52.2% girls; M = 15.14 years old at the outset) who completed surveys assaying perceptions of parent behaviors and self-reports of positive development (character, competence, connection, caring, and confidence) at annual intervals from ages 15–18. Across most lags, children’s perceptions of parenting changed in response to their own positive development with increased support and decreased psychological control. In contrast, there were no longitudinal associations from perceptions of parenting to subsequent Positive Youth Development. The results offer insight into parenting in the 21st Century, a time when youth are increasingly encouraged/required to acquire volunteer experiences designed to promote positive development. To the extent that these experiences are successful, one unexpected offshoot may be better relationships with parents.

Children and adolescents spend considerable time online. The current study investigated moderators of short-term longitudinal associations from social media use to changes in body satisfaction and physical activity. Participants (144 girls, 152 boys) were third–sixth grade students (ages 8–13) attending public schools in Florida (USA). Self-reports of social media use, body satisfaction, physical activity, and susceptibility to peer influence were completed twice, approximately 13.5 weeks apart. The results indicated that higher initial social media use was associated with greater subsequent decreases in body satisfaction and physical activity, but only for children high on susceptibility to peer influence. The findings suggest that peer conformity amplifies the risks of social media use. The fact that meaningful change can be identified across a relatively short period of time is noteworthy and demonstrates the need for careful monitoring of those who participate in social media at an early age.

While regular exercise is associated with a number of physical and mental health benefits, basing one’s self-esteem largely on exercise is likely associated with negative outcomes. In the present studies, the authors developed a novel measure of this construct, something they term “exercise overvaluation.” In Study 1, 820 participants completed an online survey measuring self-esteem, exercise attitudes and behaviors, and eating disorder symptoms. Exploratory and confirmatory factor analysis were employed to develop the 14-item Exercise Overvaluation Scale. The results provided evidence of discriminant and convergent validity and internal consistency reliability of scale scores. In Study 2, the Exercise Overvaluation Scale was administered to 134 university athletes, including those who participated in intramural sports, club sports, and collegiate athletics. The results from Study 2 supported the criterion validity and test–retest reliability of scale scores. This scale offers researchers a new tool to help understand the relationships among exercise, self-esteem, and physical and mental health outcomes.
