Research shows moderate agreement between different sources of information when assessing personality disorders (PDs) in older adults. The differences between measurement methods appear to be not only the result of measurement error, but also an indication that each source holds nonredundant information relevant to PD diagnosis. The current article examines three sources of diagnostic information (self-report, informant report, and clinical interview) and the utility of these instruments in predicting important outcomes in older adulthood. We analyzed data from 1,630 adults between the ages of 55 and 64 years participating in a longitudinal study of later life. PD symptomatology was assessed using multiple methods, which were then used to predict health, marital satisfaction, and cognitive decline. All three sources contributed significantly to the prediction of these outcomes, with important implications for the assessment of older adults in research and clinical settings.
研究表明，在评估老年人的人格障碍 (PD) 时，不同信息来源之间存在中等程度的一致性。测量方法之间的差异不仅是测量误差的结果，而且表明每个来源都持有与 PD 诊断相关的非冗余信息。本文研究了三种诊断信息来源（自我报告、知情者报告和临床访谈）以及这些工具在预测老年人重要结局方面的作用。我们分析了 1630 名年龄在 55 至 64 岁之间的成年人参与的一项关于晚年生活的纵向研究的数据。使用多种方法评估 PD 症状，然后使用这些方法来预测健康、婚姻满意度和认知能力下降。所有三个来源都对这些结果的预测有显著贡献，这对研究和临床环境中老年人的评估具有重要意义。
