BACKGROUND/OBJECTIVE: The present study aimed to contribute to analyzing the psychometric properties of the WHO Quality of Life Scale for Older Adults (WHO-QoL-Old) in a sample of older adults in Michoacán, Mexico.
111 older adults from Michoacán, Mexico, participated in the study. Confirmatory factor analysis (CFA) was conducted to test the fit of various models. Data analysis was performed using R Studio, considering the ordinal nature of the items in the model estimation method. Internal consistency was evaluated using the alpha coefficient (α) and McDonald's omega coefficient (ω).
The CFA indicated that the six-correlated-factor model proposed theoretically showed a very good fit (χ: 397.11, < 0.001; CFI: 0.958; SRMR: 0.079; RMSEA: 0.079). The factors within the model demonstrated acceptable internal consistency, with an alpha coefficient ranging from 0.739 to 0.874 and an omega coefficient ranging from 0.748 to 0.882.
It is concluded that the WHO-QoL-Old scale presents good psychometric properties for the Mexican older adult population.
背景/目的：本研究旨在助力分析世界卫生组织老年人生活质量量表（WHO-QoL-Old）在墨西哥米却肯州老年人群样本中的心理测量特性。
111名来自墨西哥米却肯州的老年人参与了该研究。进行验证性因素分析（CFA）以检验各种模型的拟合度。使用R Studio进行数据分析，在模型估计方法中考虑项目的有序性质。使用阿尔法系数（α）和麦克唐纳欧米伽系数（ω）评估内部一致性。
CFA表明，理论上提出的六相关因素模型显示出非常好的拟合度（χ：397.11，<0.001；CFI：0.958；SRMR：0.079；RMSEA：0.079）。模型中的因素显示出可接受的内部一致性，阿尔法系数范围为0.739至0.874，欧米伽系数范围为0.748至0.882。
得出结论，WHO-QoL-Old量表对于墨西哥老年人群体具有良好的心理测量特性。
