The present study examined whether self-efficacy mediates the relationship between family social influence and physical activity among youth who have experienced a recent lapse in their physical activity participation. Using a prospective, longitudinal design, participants completed measures of social influence, self-regulatory efficacy and physical activity. Only those participants whose physical activity declined were retained for further analysis. Self-regulatory efficacy partially mediated the relationship between family social influence and physical activity, with self-efficacy mediating 36 percent of the total effect. The results provide support for self-regulatory efficacy as a mediator and provide preliminary insight into the potential mechanisms for preventing lapses in activity from developing into prolonged periods of inactivity within this population.

    • "In preschoolers, direct and indirect effects via child enjoyment of physical activity have been reported between family support and objectively measured physical activity [27]. Both direct and indirect associations via self-efficacy have been found for family support for physical activity [28] and family social influence (modelling and encouragement) [29] among adolescent girls and youth whose physical activity declined over four months, respectively. Motl et al. [30] also found evidence of an indirect association between access to physical activity equipment in the home and physical activity among adolescent girls operating via self-efficacy. "

    ABSTRACT: Background Sport participation makes an important contribution to children’s overall physical activity. Understanding influences on sports participation is important and the family environment is considered key, however few studies have explored the mechanisms by which the family environment influences children’s sport participation. The purpose of this study was to examine whether attitude, perceived behavioural control, health belief and enjoyment mediate associations between the family environment and 10–12 year-old children’s sports participation. Methods Children aged 10–12 years ( = 7234) and one of their parents (n = 6002) were recruited from 175 schools in seven European countries in 2010. Children self-reported their weekly duration of sports participation, physical activity equipment items at home and the four potential mediator variables. Parents responded to items on financial, logistic and emotional support, reinforcement, modelling and co-participation in physical activity. Cross-sectional single and multiple mediation analyses were performed for 4952 children with complete data using multi-level regression analyses. Results Availability of equipment (OR = 1.16), financial (OR = 1.53), logistic (OR = 1.47) and emotional (OR = 1.51) support, and parental modelling (OR = 1.07) were positively associated with participation in ≥ 30mins/wk of sport. Attitude, beliefs, perceived behavioural control and enjoyment mediated and explained between 21-34% of these associations. Perceived behavioural control contributed the most to the mediated effect for each aspect of the family environment. Conclusions Both direct (unmediated) and indirect (mediated) associations were found between most family environment variables and children’s sports participation. Thus, family-based physical activity interventions that focus on enhancing the family environment to support children’s sport participation are warranted.

    • "Taken together, this study highlights the importance of parent social support on engaging adolescents in PA. Overall, investigators have found social and cognitive variables to account for 10–25% of the variance in adolescent PA (Frenn et al., 2005; Robbins, Wu, Sikorskii, & Morley, 2008; Shields et al., 2008), and similarly, the current study found parent SS and SE to account for approximately 8% of the variance in adolescent PA. This suggests the importance of continuing to examine other variables to capture more of the variance accounting for adolescent PA. "

    ABSTRACT: Objective: Previous research has shown that cognitive factors may account for the relationship between interpersonal factors and health behaviors. Given these findings, the current study sought to further explore the direct and indirect relationship between parental social support and adolescent physical activity (PA). Method: Data were collected from 1,421 sixth graders (73% Black, 54% females, 71% on free or reduced lunch) in South Carolina. Measures for emotional social support, instrumental social support, and adolescent self-efficacy (SE) were assessed and PA was assessed via accelerometry. Results: Parent instrumental social support was directly related to girls' PA and parent emotional social support was inversely related to girls' PA. Parent instrumental social support was indirectly related to boys' PA through boys' SE. The covaried association of SE with PA was significant for boys and marginal for girls. Conclusions: SE for overcoming barriers may be an important construct for understanding the relationship between parent instrumental social support and boys' PA in underserved populations. The mechanisms for engaging in PA may be different for adolescent girls and boys.

    • "Familial support has been reported effective in producing health-promoting behaviors among patients with cardiovascular disease (51) and for chronically ill family members achieving physical activity guidelines and practicing better dietary behaviors (52). Finally, family support consistently correlates positively with physical activity levels (49,53,54). "

    ABSTRACT: The purpose of this article is to emphasize the value of the family as a source of behavior change, particularly with respect to attaining achievable goals of weight loss and regular physical activity for youth and their families. We present a review of the literature, providing support for the value of the family in influencing children to form good diet and exercise behaviors and as a source of support and motivation for individuals seeking to lose or control their weight and to start and maintain a physically active lifestyle. Recognizing the importance of family behavior in the development of weight control and weight loss activities is essential. Future work should focus on identifying measurable parameters of family-level weight control behaviors and ways to apply those parameters to help create new interventions that use the strengths of the family for achieving weight control goals.
