Social support (SS) from parents and peers are key reinforcing factors in the Youth Physical Activity Promotion (YPAP) model. This study aims to identify the relative contribution of parental and peer SS on youth participation in moderate to vigorous physical activity (MVPA). Participants included 203 high school students (n = 125 girls; mean age 14.99 ± 1.55 years). MVPA was assessed by accelerometry. SS influences were evaluated using a well-established scale. Structural equation modeling measured (AMOS, Version 19) the relative fit of the YPAP models using both parental and peer SS. Parental SS had significant associations with both predisposing factors, enjoyment (β = .62, p < .01), and self-efficacy (β= .32, p < .01), as well a direct effect on MVPA (β = .30, p < .01). Peer SS had direct effect on MVPA (β = .33, p < .05), also significantly influenced levels of enjoyment (β = .47, p < .01) and self-efficacy (β = .67, p < .01). In both models self-efficacy mediated the influence on MVPA. The direct effects for parents and peers were similar. This demonstrates that both parental and peer social support exert a strong influence on adolescent MVPA.
来自父母和同伴的社会支持（SS）是青少年体育活动促进（YPAP）模型中的关键强化因素。本研究旨在确定父母和同伴社会支持对青少年参与中度至剧烈体育活动（MVPA）的相对贡献。研究对象包括203名高中生（n = 125名女生；平均年龄14.99 ± 1.55岁）。通过加速度计评估MVPA。使用一个成熟的量表评估社会支持的影响。结构方程模型（AMOS，版本19）使用父母和同伴社会支持来测量YPAP模型的相对拟合度。父母社会支持与易感性因素、愉悦感（β = .62，p < .01）和自我效能感（β = .32，p < .01）均有显著关联，并且对MVPA有直接影响（β = .30，p < .01）。同伴社会支持对MVPA有直接影响（β = .33，p < .05），也显著影响愉悦感水平（β = .47，p < .01）和自我效能感（β = .67，p < .01）。在两个模型中，自我效能感介导了对MVPA的影响。父母和同伴的直接影响相似。这表明父母和同伴的社会支持对青少年MVPA都有很强的影响。
