Abstract

Abstract Negative stereotypes about older workers can result in different types of age discrimination. The aim of this study was to run a transcultural adaptation and validation of the Nordic Age Discrimination Scale (NADS) into Spanish. Three independent samples of Chilean (N = 301), Colombian (N = 150), and Spanish (N = 209) workers over the age of 45, from different sectors and professional categories, answered a questionnaire including the NADS scale, measures of perceptions of inequality, workplace harassment and several scales related to outcome variables to test criterion and construct validity. The reliability index for the NADS was .85, a similar value for both Cronbach’s alpha (α) and McDonald’s omega (ω). CFA by country suggest good fit of this single-dimension structure in a final version of 5 items, and it presents scalar invariance; using the modification indices, partial invariance is achieved at the level of the variance of the errors. Both criterion and construct validity were verified, with strong evidence for criterion validity, and moderate results for construct validity. Therefore, the Spanish version of NADS had a single-dimension structure and adequate psychometric properties being a useful tool in measuring perceptions of age discrimination in different countries.

北欧年龄歧视量表对西班牙语工作人口的跨文化验证

摘要对老年工人的负面刻板印象可能导致不同类型的年龄歧视。本研究的目的是将北欧年龄歧视量表（NADS）进行跨文化改编和西班牙语验证。来自不同行业和专业类别的智利（N=301）、哥伦比亚（N=150）和西班牙（N=209）45岁以上工人的三个独立样本回答了一份问卷，其中包括NADS量表、对不平等的感知测量、工作场所骚扰以及与结果变量相关的几个量表，以检验标准和结构有效性。NADS的可靠性指数为.85，Cronbachα（α）和McDonaldω（ω）的值相似。各国的CFA表明，这种一维结构在5个项目的最终版本中很好地拟合，并且它具有标量不变性；利用修正指数，在误差方差水平上实现了部分不变性。标准有效性和结构有效性都得到了验证，标准有效性证据确凿，结构有效性结果适中。因此，西班牙版本的NADS具有单一的维度结构和足够的心理测量特性，是衡量不同国家对年龄歧视看法的有用工具。
