The purpose of the current study is to test the self-determination theory (SDT) continuum hypothesis of motivation using latent profile analysis (LPA). A total of 3,220 school students took part in the study. We compared LPA solutions estimated using the four motivation types versus the two higher-order dimensions to assess their degree of correspondence to the SDT continuum hypothesis. To examine the concurrent validity of the profiles, we also verified their associations with three predictors (age, gender, perception of physical education teachers' autonomy-supportive behaviors) and two outcomes variables (perceived competence and intentions to be physically active). The results showed that profiling using the four motivation types provides more differentiated and meaningful description of responses to the Perceived Locus of Causality Scale, compared with profiling using two higher-order factors. In general, the results of the current study were consistent with the SDT continuum hypothesis of human motivation.
本研究的目的是使用潜在剖面分析（LPA）来检验动机的自我决定理论（SDT）连续体假设。共有3220名在校学生参与了这项研究。我们比较了使用四种动机类型与两个高阶维度估计的LPA解决方案，以评估它们与SDT连续体假设的对应程度。为了检验剖面的同时效度，我们还验证了它们与三个预测变量（年龄、性别、对体育教师自主支持行为的认知）和两个结果变量（感知能力和身体活动意图）之间的关联。结果表明，与使用两个高阶因素进行剖面分析相比，使用四种动机类型进行剖面分析能更具区分性且更有意义地描述对因果关系感知量表的反应。总体而言，本研究结果与人类动机的SDT连续体假设一致。
