Self-determination is a psychological construct that applies to both the general population and to individuals with disabilities that can be self-determined with adequate accommodations and opportunities. As the relevance of self-determination-related skills in life has been recently acknowledged, researchers have created a measure to assess self-determination in adolescents and young adults with and without disabilities. The Self-Determination Inventory: Student Report (Spanish interim version) is empirically being validated into Spanish.
As this scale is the first assessment addressed to all youth, further exploration of its psychometric properties is required to ensure the reliability of the self-determination measurement and gain further insight into the construct when applied to youth with and without disabilities.
More than 600 participants were asked to complete the scale. The impact of disability on the item response distributions across the dimensions of self-determination was explored.
Differential item functioning (DIF) was found in only 5 of the scale's 45 items. Differences primary favored youth without disabilities.
The weak presence of DIF across the items supports the instrument's psychometrical robustness when measuring self-determination in youth with and without disabilities and provides further understanding of the self-determination construct. Implications and future research directions are also discussed.
自主性是一种心理结构，既适用于普通人群，也适用于那些通过适当的适应和机会可以自主的残疾人群体。由于自主性相关技能在生活中的重要性最近得到了认可，研究人员已经创建了一种评估残疾和非残疾青少年和年轻人自主性的方法。《自主量表：学生报告》（西班牙语临时版）正在被实证验证为西班牙语版。
由于该量表是第一个针对所有青少年的评估工具，因此需要进一步探索其心理测量学特性，以确保自主测量的可靠性，并在应用于残疾和非残疾青少年时深入了解该构念。
要求 600 多名参与者完成该量表。研究了残疾对自主决定各维度的项目反应分布的影响。
仅在该量表的 45 个项目中的 5 个项目中发现了差异项目功能（DIF）。差异主要有利于无残疾的年轻人。
项目之间 DIF 的存在较弱，支持了该工具在测量残疾和非残疾青少年自主性时的心理测量稳健性，并进一步理解了自主性构念。还讨论了其影响和未来的研究方向。
