We conducted a theoretical and psychometric evaluation of self-determination theory's "relative autonomy continuum" (RAC), an important aspect of the theory whose validity has recently been questioned. We first derived a Comprehensive Relative Autonomy Index (C-RAI) containing six subscales and 24 items, by conducting a paired paraphrase content analysis of existing RAI measures. We administered the C-RAI to multiple U.S. and Russian samples, assessing motivation to attend class, study a major, and take responsibility. Item-level and scale-level multidimensional scaling analyses, confirmatory factor analyses, and simplex/circumplex modeling analyses reaffirmed the validity of the RAC, across multiple samples, stems, and studies. Validation analyses predicting subjective well-being and trait autonomy from the six separate subscales, in combination with various higher order composites (weighted and unweighted), showed that an aggregate unweighted RAI score provides the most unbiased and efficient indicator of the overall quality of motivation within the behavioral domain being assessed.
我们对自我决定理论的“相对自主性连续体”（RAC）进行了理论和心理测量评估，这是该理论的一个重要方面，其有效性最近受到了质疑。我们首先通过对现有的 RAC 测量方法进行配对释义内容分析，得出了包含六个分量表和 24 个项目的综合相对自主性指数（C-RAI）。我们对多个美国和俄罗斯样本进行了测试，评估了他们参加课程、学习专业和承担责任的动机。项目级和量表级多维标度分析、验证性因素分析和单形/围道模型分析都在多个样本、样本和研究中重新证实了 RAC 的有效性。从六个单独的分量表中预测主观幸福感和特质自主性的验证分析，以及与各种更高阶综合（加权和非加权）的结合，表明加权和非加权 RAI 总得分都提供了最无偏和有效的动机整体质量指标，这是在被评估的行为领域内。
