Abstract

The aim of the present study was to analyze the psychometric properties of the State-Trait Anxiety Inventory- Trait dimension (STAI-T), Form X. A total of 798 Argentinian adolescents aged between 12 and 18 years (M = 14; SD = 1.31) participated in this study. The psychometric properties of the instrument were analyzed from the contributions of the Rasch model, which allowed us to assess the measurement model fit, response threshold order, item and person fit, local dependence, differential item functioning (DIF), reliability, targeting, and unidimensionality. The results showed that the STAI-T, anxiety-absent items, and anxiety-present items presented values close to the expected ones for item and person fit, ordered response categories, appropriate reliability levels, and adequate targeting. Only in anxiety-absent items, it was possible to verify compliance with unidimensionality, whereas in anxiety-present items there were items with local dependence or showing DIF. The present study provides empirical evidence based on a rigorous measurement model that allows corroborating the validity of the scale to assess anxiety in Argentinian adolescents.

阿根廷青少年国家特质焦虑量表的心理测量特性

本研究的目的是分析X型状态-特质焦虑量表（STAI-T）的心理测量特性。共有798名年龄在12至18岁之间的阿根廷青少年（M=14；SD=1.31）参与了本研究。从Rasch模型的贡献分析了该工具的心理测量特性，该模型使我们能够评估测量模型拟合、反应阈值顺序、项目和个人拟合、局部依赖性、差异项目功能（DIF）、可靠性、目标性和单维度。结果表明，STAI-T、焦虑缺失项目和焦虑存在项目在项目和个人适合度、有序的反应类别、适当的可靠性水平和适当的针对性方面的值接近预期值。只有在不存在焦虑的项目中，才有可能验证对单维度的依从性，而在存在焦虑的项中，有具有局部依赖性或表现出DIF的项目。本研究提供了基于严格测量模型的经验证据，该模型可以证实该量表评估阿根廷青少年焦虑的有效性。
