Table_1_Transition to Adulthood Autonomy Scale for Young People: Design and Validation.pdf

Given that autonomy is a fundamental process in the transition to adulthood, there are several scales that measure the concept as a main construct or a constituent feature of broader constructs. However, most of these scales are based on a notion of autonomy focused on the individual, while the proposed scale aims to incorporate the idea of the individual mediated by others and society. This article aims to show the results of the design and validation process of the Transition to Adulthood Autonomy Scale (EDATVA), which was developed using this approach. A group of 61 items with a Likert-type response scale of four options was used on a sample of 1,148 Spanish and Colombian individuals, aged between 16 and 21. A systematic process was performed using an exploratory factorial analysis. Additional indexes were calculated from the Rasch Model. The matrices obtained from the factorial analysis gave rise to a 4-factor structure comprising a total of 19 items with weights >0.3. In the case of Spain, the KMO test returned a value of 0.80 and in the case of Colombia, 0.83. In the Rasch model, the Item Separation Reliability (0.99) indicates that the items constitute a well-defined variable that meets the local independence assumption. Cronbach's alpha for the Spanish sample was 0.86 and for the Colombian sample 0.85. In conclusion, this new scale consists of four dimensions: self-organization, understanding context, critical thinking, and socio-political engagement. The scale is easy to use and interpret, especially considering the age range of the target population and its possible uses within the contexts of assessing and intervening in young people's behavior. Due to its characteristics, it can be used in family, educational, and social contexts. This scale is valuable for research because its optimal psychometric properties provide an alternative way of understanding autonomy.

鉴于自主性是向成年期过渡进程中的核心过程，当前已有若干量表将自主性作为核心构念或更宽泛构念的组成特征进行测量。然而，此类量表大多基于以个体为中心的自主性概念，而本研究拟开发的量表则旨在纳入个体受他人与社会中介调节的理念。本文旨在呈现采用上述思路开发的向成年期过渡自主性量表（Transition to Adulthood Autonomy Scale, EDATVA）的设计与验证流程结果。研究以1148名年龄介于16至21岁的西班牙与哥伦比亚个体为研究样本，采用包含61个条目、4级李克特式作答选项的初始量表。研究通过探索性因素分析开展系统性流程，并基于拉施模型（Rasch Model）计算了额外指标。因素分析得到的矩阵最终确立了四因素结构，共保留19个因子载荷大于0.3的条目。其中西班牙样本的KMO检验值为0.80，哥伦比亚样本为0.83。拉施模型中的条目分离信度（Item Separation Reliability）为0.99，表明该量表条目构成了一个界定清晰的变量，且满足局部独立性假设。西班牙样本的克朗巴哈α系数（Cronbach's alpha）为0.86，哥伦比亚样本为0.85。综上，该新型量表包含四个维度：自我组织、情境认知、批判性思维以及社会政治参与。该量表易于使用与解读，尤其适配目标人群的年龄范围，且可在青少年行为评估与干预场景中发挥作用。结合其特性，该量表可应用于家庭、教育及社会场景。该量表具备优异的心理测量学属性，为自主性的研究提供了全新视角，因此具有重要的研究价值。
