This study compared the predictive validity of physician-evaluated morbidity and self-reported morbidity on disability among adults.
Subjects from a large national survey (n = 6913) received a detailed medical examination by a physician and were asked about the presence of 36 health conditions at baseline. Disability measured 10 and 15 years later was regressed on the morbidity measures and covariates with tobit models.
Although physician-evaluated morbidity and self-reported morbidity were associated with greater disability, self-reports of chronic nonserious illnesses manifested greater predictive validity. Disability was also higher for obese subjects and those of lower socioeconomic status.
The findings demonstrate the predictive utility of self-reported morbidity measures on functional disability.
本研究比较了医生评估的发病率和自我报告的发病率对成年人残疾情况的预测效度。
来自一项大型全国性调查(n = 6913)的受试者接受了医生的详细体格检查,并在基线时被问及36种健康状况。使用托比特模型,将10年和15年后测量的残疾情况与发病率测量值及协变量进行回归分析。
尽管医生评估的发病率和自我报告的发病率都与更高的残疾率相关,但慢性非严重疾病的自我报告表现出更高的预测效度。肥胖受试者和社会经济地位较低者的残疾率也更高。
研究结果证明了自我报告的发病率测量对功能残疾的预测效用。
