This study aimed to clarify the construct validity of the Questionnaire for medical checkup of old-old (QMCOO).
In this cross-sectional study, questionnaires including the QMCOO were distributed to 1,953 older adults, and responses were returned by mail. We conducted an exploratory factor analysis (EFA) for the QMCOO among older participants (age ≥75 years) and extracted the relevant factors. Next, we structured the model for the QMCOO based on these factors and conducted a confirmatory factor analysis (CFA) using structural equation modeling. We conducted a CFA among young-older participants (age 65 to <75 years) for the same model.
Of the 1,110 (53.5%) adults who responded, data from the 994 respondents who provided complete answers were analyzed. Five factors were extracted from the results of the EFA: physical and mental condition, relationship with society, eating and smoking, chance for exercise, and cognitive function. The results of the CFA were as follows: comparative fit index (CFI) = 0.899, adjusted goodness of fit index (AGFI) = 0.965, root mean square error of approximation (RMSEA) = 0.034, and standardized root mean square residual (SRMR) = 0.040. Meanwhile, the results for young-older participants were as follows: CFI = 0.886, AGFI = 0.942, RMSEA = 0.035, and SRMR = 0.048.
The QMCOO assessed health condition and was composed of multiple factors associated with frailty. The CFA results indicated that the model fit was good. The QMCOO showed sufficient structural validity. Therefore, the construct validity of the QMCOO was shown.
本研究旨在阐明高龄老人健康体检问卷（QMCOO）的结构效度。
在这项横断面研究中，向1953名老年人发放了包括QMCOO在内的问卷，并通过邮寄方式回收答案。我们对老年参与者（年龄≥75岁）中的QMCOO进行了探索性因子分析（EFA），并提取了相关因子。接下来，我们基于这些因子构建了QMCOO模型，并使用结构方程模型进行了验证性因子分析（CFA）。我们对同一年轻老年参与者（年龄65至<75岁）进行了相同模型的CFA。
在1110名（53.5%）做出回应的成年人中，分析了994名提供完整答案的受访者的数据。从EFA结果中提取了五个因子：身心健康状况、与社会的关系、饮食与吸烟、锻炼机会和认知功能。CFA结果如下：比较拟合指数（CFI）=0.899，调整后拟合优度指数（AGFI）=0.965，近似均方根误差（RMSEA）=0.034，标准化均方根残差（SRMR）=0.040。同时，年轻老年参与者的结果如下：CFI = 0.886，AGFI = 0.942，RMSEA = 0.035，SRMR = 0.048。
QMCOO评估了健康状况，由与衰弱相关的多个因子组成。CFA结果表明模型拟合良好。QMCOO显示出足够的结构效度。因此，QMCOO的结构效度得到了证明。
