This study investigated the temporal relations of adolescents’ basic need satisfaction in physical education (PE) and global self-worth in a sample of 3,398 lower and upper secondary school students (49% boys, 51% girls, average age T1 = 15.00, SD = 1.79). Four models and competing hypotheses were tested, and the model with bidirectional paths specified showed the best fit to the data. The bidirectional effect estimates suggest not only that basic need satisfaction in PE predicts global self-worth development but also that adolescents’ perceptions of global self-worth predict the degree to which they experience basic need satisfaction in PE. Findings could suggest that students with low global self-worth are less sensitive to basic need support in PE. These students may need personally tailored need-supportive initiatives in order to develop basic need satisfaction in PE and, thus, global self-worth through PE.

本研究以 3,398 名初中和高中学生为样本（49% 男孩，51% 女孩，平均年龄 T1 = 15.00，SD  = 1.79）。测试了四种模型和竞争假设，指定双向路径的模型显示了与数据的最佳拟合。双向效应估计不仅表明体育运动中的基本需求满足可以预测整体自我价值的发展，而且青少年对整体自我价值的感知也可以预测他们在体育运动中体验基本需求满足的程度。研究结果可能表明，整体自我价值感较低的学生对体育方面的基本需求支持不太敏感。这些学生可能需要量身定制的需求支持计划，以便满足体育方面的基本需求，从而通过体育实现全面的自我价值。
