A three-wave prospective study was conducted to provide a better understanding of the ability of the integrated model of self-determination theory (SDT) and the theory of planned behavior (TPB) to predict future physical activity (PA) engagement among adolescents. Nearly 2500 secondary school students from China were recruited to test the hypothesized pathway from autonomous motivation from SDT at baseline (T1) through the constructs of TPB one month later (T2) on leisure-time PA levels of secondary school students three months later (T3). The findings revealed that the structural equation models yielded excellent fit indices with χ = 1858.989, = 257, CFI = 0.936, TLI = 0.926, RMSEA = 0.050 [90% CI = 0.048 to 0.052], and SRMR = 0.032. In particular, autonomous motivation at T1 was positively associated with attitude (R = 0.160), subjective norms (R = 0.160), and perceived behavioral control (PBC) (R = 0.173) at T2 ( = 0.395 to 0.414, < 0.001) and subsequently associated with intention at T2 (R = 0.875, = 0.112 to 0.478, < 0.001). T2 intention was positively associated with leisure-time PA levels (R = 0.004) at T3. Our findings contribute to a better understanding of the motivational mechanisms and social cognition processes involved in predicting adolescents' leisure-time PA levels among adolescents.
开展了一项三波前瞻性研究，以更好地了解自我决定理论（SDT）与计划行为理论（TPB）的整合模型预测青少年未来身体活动（PA）参与度的能力。招募了近2500名来自中国的中学生，以测试从基线时（T1）自我决定理论中的自主动机，经过一个月后的计划行为理论结构（T2），到三个月后的中学生休闲时间身体活动水平（T3）的假设路径。研究结果显示，结构方程模型产生了出色的拟合指数，χ = 1858.989， = 257，CFI = 0.936，TLI = 0.926，RMSEA = 0.050 [90% CI = 0.048至0.052]，以及SRMR = 0.032。具体而言，T1时的自主动机与T2时的态度（R = 0.160）、主观规范（R = 0.160）和感知行为控制（PBC）（R = 0.173）呈正相关（ = 0.395至0.414， < 0.001），随后与T2时的意图呈正相关（R = 0.875， = 0.112至0.478， < 0.001）。T2时的意图与T3时的休闲时间身体活动水平呈正相关（R = 0.004）。我们的研究结果有助于更好地理解预测青少年休闲时间身体活动水平所涉及的动机机制和社会认知过程。
