OBJECTIVE Longitudinal measurement invariance analyses are an important way to assess a test's ability to estimate the underlying construct over time, ensuring that cognitive scores across visits represent a similar underlying construct, and that changes in test performance are attributable to individual change in cognitive abilities. We aimed to evaluate longitudinal measurement invariance in a large, social and culturally diverse sample over time. METHODS A total of 5,949 participants from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) were included, whose cognition was reassessed after four years. Longitudinal measurement invariance analysis was performed by comparing a nested series of multiple-group confirmatory factor analysis models (for memory and executive function factors). RESULTS Configural, metric, scalar and strict invariance were tested and supported over time. CONCLUSION Cognitive temporal changes in this sample are more likely to be due to normal and/or pathological aging. Testing longitudinal measurement invariance is essential for diverse samples at high risk of dementia, such as in low- and middle-income countries.

来自 ELSA-Brasil 研究的不同样本中神经心理学测试的纵向测量不变性

目标 纵向测量不变性分析是评估测试随时间推移估计基础结构的能力的重要方法,可确保跨访问的认知分数代表相似的基础结构,并且测试性能的变化可归因于个体认知能力的变化。我们的目标是在一个大的、社会和文化多样化的样本中随着时间的推移评估纵向测量的不变性。方法 共有 5,949 名来自巴西成人健康纵向研究 (ELSA-Brasil) 的参与者被纳入研究,四年后对他们的认知能力进行了重新评估。通过比较一系列嵌套的多组验证性因素分析模型(记忆和执行功能因素)进行纵向测量不变性分析。结果 配置、公制、随着时间的推移,标量和严格不变性得到了测试和支持。结论 该样本中的认知时间变化更有可能是由于正常和/或病理性衰老。测试纵向测量不变性对于痴呆症高风险的不同样本至关重要,例如在低收入和中等收入国家。
