尽管研究关注于了解心理需求满足(PNS)、中等强度到剧烈的体力活动(MVPA)和健康相关的生活质量(HRQOL)之间的关系，但方法上的限制使建立相互作用和中介效应变得困难。研究了4年来PNS和MVPA之间的相互关系，并考察了它们对青少年HRQOL维度变化的影响。从5/6年级开始，每隔4个月收集932名青少年(M-年龄=10.9岁)的自我报告数据。在人与人之间和人内层面，较早的PNS预测较晚的MVPA，而较早的MVPA不能预测较晚的PNS。MVPA的增加与身体(Beta(线性)=.61，Beta(二次)=.77，PS=.03)和学校功能(线性=.68，二次=.84，PS=.03)的更大变化有关，但与HRQOL的其他维度(p>；.05)无关。PNS的减少与HRQOL的任何维度都没有关联。培养青少年的PNS可能是增加MVPA的起点，这反过来可能会提高HRQOL的某些维度。
Despite research attention toward understanding relationships between psychological need satisfaction (PNS), moderate-to-vigorous-intensity physical activity (MVPA), and health-related quality of life (HRQoL), methodological limitations make it difficult to establish reciprocal and mediating effects. Reciprocal relationships between PNS and MVPA were examined over 4 years, and their effects on adolescents' change in dimensions of HRQoL were examined. Self-reported data were collected from 932 adolescents (M-age = 10.9 years) every 4 months beginning in Grades 5/6. At the between-persons and within-person level, earlier PNS predicted later MVPA whereas earlier MVPA did not predict later PNS. Increases in MVPA were associated with greater change in physical (beta(linear) = .61, beta(quadratic) = .77, ps = .03) and school functioning (linear = .68, quadratic = .84, ps = .03) but no other dimensions of HRQoL (p > .05). Decreases in PNS were not associated with any of the dimensions of HRQoL. Fostering adolescents' PNS could be a starting point to increase MVPA, which, in turn, may enhance select dimensions of HRQoL.
