A new measure of self-determination, the Self-Determination Inventory: Student Report (Spanish version), has recently been adapted and empirically validated in Spanish language. As it is the first instrument intended to measure self-determination in youth with and without disabilities, there is a need to further explore and strengthen its psychometric analysis based on item response patterns.
Through item response theory approach, this study examined item observed distributions across the essential characteristics of self-determination.
The results demonstrated satisfactory to excellent item functioning patterns across characteristics, particularly within agentic action domains. Increased variability across items was also found within action-control beliefs dimensions, specifically within the self-realisation subdomain.
These findings further support the instrument's psychometric properties and outline future research directions.
一种新的自主性衡量工具，即《自主量表：学生报告》（西班牙语版），最近已被改编并在西班牙语中进行了实证验证。由于这是第一个旨在衡量残疾和非残疾青年自主性的工具，因此需要进一步根据项目反应模式探索和加强其心理计量学分析。
通过项目反应理论方法，本研究考察了项目在自主性基本特征上的观察分布情况。
结果表明，在各个特征上，项目的功能模式都令人满意到非常好，特别是在能动性行动领域。在行动控制信念维度内，特别是在自我实现子领域内，也发现了项目之间的可变性增加。
这些发现进一步支持了该工具的心理计量学特性，并概述了未来的研究方向。
