Abstract

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.

Methods: 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).

Results: The CFA indicated that the six-correlated-factor model proposed theoretically showed a very good fit (χ²: 397.11, p < 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.

Conclusions: It is concluded that the WHO-QoL-Old scale presents good psychometric properties for the Mexican older adult population.

世界卫生组织老年人生活质量量表（WHO-QoL-Old）在墨西哥人群中的心理测量特性。

背景/目的：本研究旨在帮助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样本中的心理测量特性。进行了确证因子分析（CFA），以测试各种模型的拟合度。数据分析使用 R Studio 进行，在模型估计方法中考虑到了项目的序数性质。使用阿尔法系数（α）和麦当劳欧米茄系数（ω）评估内部一致性：CFA 结果表明，理论上提出的六相关因子模型具有很好的拟合效果（χ2：397.11，p < 0.001；CFI：0.958；SRMR：0.079；RMSEA：0.079）。模型中各因子的内部一致性良好，α系数在 0.739 至 0.874 之间，Ω系数在 0.748 至 0.882 之间：结论：WHO-QoL-Old 量表具有良好的心理测量特性，适用于墨西哥老年人群。
