Career Adapt-Abilities Scale (CAAS-Brazil): Psychometric properties, differences as a function of sociodemographic variables and normative standards

Abstract This article aimed to propose normative standards for the Career Adapt-Abilities Scale (CAAS-Brazil) considering differences in terms of sociodemographic variables: gender, marital status, age group, education level, and income. The sample consisted of 2999 individuals, within the age range of 14 to 77 years, mostly women (63%) from 21 Brazilian states. The psychometric properties of CAAS-Brazil were investigated using Item Response Theory and the Omega coefficient. Results showed invariance for the CAAS-Brazil and greater mean differences in the variables age group, education, and income. From this, normative standards for the overall sample were presented and divided considering the variables that showed differences. The normative standards presented in this article will enable career guidance professionals to interpret the career adaptability scores of their students, making the assessment more robust.摘要 本研究旨在结合社会人口学变量（性别、婚姻状况、年龄组别、受教育水平与收入水平）的差异，制定巴西版职业适应力量表（Career Adapt-Abilities Scale，CAAS-Brazil）的常模标准。本研究样本涵盖2999名年龄介于14至77岁的个体，其中女性占比63%，来自巴西21个州。本研究采用项目反应理论（Item Response Theory）与欧米茄系数，对巴西版职业适应力量表的心理测量学属性进行了考察。结果显示，巴西版职业适应力量表具备测量不变性，且在年龄组别、受教育水平与收入水平变量上存在显著组间均值差异。基于上述结果，本研究制定了总样本的常模标准，并依据存在显著差异的变量进行了分组。本文所提出的常模标准，可帮助职业指导从业者解读其服务对象的职业适应力得分，使评估结果更具可靠性与严谨性。
