To assess the effectiveness of a positive youth development (PYD)-based sports mentorship program on the physical and mental well-being of adolescents recruited in a community setting.
This is a randomized controlled trial in which we recruited students from 12 secondary schools in Hong Kong, China. Participants were randomly assigned in a 1:1 ratio to an intervention or a control arm after stratification for school from October 2013 to June 2014. Participants were not blinded to allocation because of the nature of the intervention. Students in the intervention arm received an after-school, PYD-based sports mentorship for 18 weeks. Each weekly session lasted 90 minutes. Students in the control arm received exclusive access to a health education Web site.
Six hundred and sixty-four students (mean age 12.3 years [SD 0.76]; 386 girls [58.1%]) completed baseline and postintervention assessments. The intervention improved students' mental well-being (Cohen's , 0.25; 95% confidence interval [CI], 0.10 to 0.40; = .001), self-efficacy (Cohen's , 0.22; 95% CI, 0.07 to 0.37; = .01), resilience (Cohen's , 0.19; 95% CI, 0.03 to 0.34; = .02), physical fitness (flexibility [Cohen's , 0.28; 95% CI, 0.13 to 0.43; = .02], lower limb muscle strength [Cohen's , 0.18; 95% CI, 0.03 to 0.33; = .03], and dynamic balance [Cohen's , 0.21; 95% CI, 0.06 to 0.37; = .01]), and physical activity levels (Cohen's , 0.39; 95% CI, 0.24 to 0.55; < .0001). The intervention did not significantly improve physical well-being (Cohen's , -0.01; 95% CI, -0.17 to 0.14; = .86), BMI scores (Cohen's , -0.03; 95% CI, -0.18 to 0.12; = .69), body fat proportion (Cohen's , -0.15; 95% CI, -0.31 to 0.00; = .051), and social connectedness (Cohen's , -0.03; 95% CI, -0.18 to 0.12; = .72).
A PYD-based sports mentorship intervention improved healthy adolescents' mental well-being, psychological assets, physical fitness, and physical activity levels.
评估基于积极青年发展（PYD）的体育辅导计划对社区环境中招募的青少年身心健康的有效性。
这是一项随机对照试验，我们从中国香港的 12 所中学招募了学生。参与者在 2013 年 10 月至 2014 年 6 月期间按学校分层，以 1:1 的比例随机分配到干预组或对照组。由于干预的性质，参与者无法对分配情况进行盲法。干预组的学生接受了 18 周的课后基于 PYD 的体育辅导。每个每周课程持续 90 分钟。对照组的学生仅可以访问健康教育网站。
664 名学生（平均年龄 12.3 岁[SD 0.76]；386 名女生[58.1%]）完成了基线和干预后评估。干预措施提高了学生的心理健康（Cohen's, 0.25；95%置信区间[CI]，0.10 至 0.40； =.001）、自我效能感（Cohen's, 0.22；95%CI，0.07 至 0.37； =.01）、适应力（Cohen's, 0.19；95%CI，0.03 至 0.34； =.02）、身体健康（柔韧性[Cohen's, 0.28；95%CI，0.13 至 0.43； =.02]、下肢肌肉力量[Cohen's, 0.18；95%CI，0.03 至 0.33； =.03]和动态平衡[Cohen's, 0.21；95%CI，0.06 至 0.37； =.01]）和身体活动水平（Cohen's, 0.39；95%CI，0.24 至 0.55； <.0001）。干预措施并未显著改善身体健康（Cohen's, -0.01；95%CI，-0.17 至 0.14； =.86）、BMI 评分（Cohen's, -0.03；95%CI，-0.18 至 0.12； =.69）、体脂比例（Cohen's, -0.15；95%CI，-0.31 至 0.00； =.051）和社交联系（Cohen's, -0.03；95%CI，-0.18 至 0.12； =.72）。
基于 PYD 的体育辅导干预措施提高了健康青少年的心理健康、心理资产、身体健康和身体活动水平。
