知觉控制的两个方面，即控制源（locus of control，简称PNC）和知觉胜任力（percepted competence，简称COM），在人格与衰老研究中备受关注。主要是，这些概念被认为是稳定的变量，预测一系列的结果有相当大的希望。作者专注于自我报告的BMI和COM的周与周之间的人内变异性。使用收集的数据超过7个月，作者首先表明，一个小组的老年参与者的反应是结构上一致的占主导地位的概念的感知控制和反应保持一个基本的结构，在频繁重复的协议。他们接下来表明，每周测量的人内变化是一致的信息，而不是“噪音”，周间变异幅度的个体差异是一个相对稳定的属性，预测5年后的死亡率状态。
Two aspects of perceived control, locus of control (LOG) and perceived competence (COM), command significant attention in personality and aging research. Mainly, these concepts are regarded as stable variables of considerable promise for predicting a range of outcomes. The authors concentrate on week-to-week within-person variability in self-reported LOC and COM. Using data collected over 7 months, the authors first demonstrate that the responses of a panel of older participants are structurally consistent with dominant conceptions of perceived control and that the responses maintain an underlying structure over the frequently repeated protocol. They next show that the within-person variation over weekly measurements is coherent information rather than ''noise'' and that individual differences in magnitude of week-to-week variability are a relatively stable attribute that predicts mortality status 5 years later Implications of the findings for both methodological and substantive concerns are discussed.
