背景和目的：在阿尔茨海默病（AD）诊断前的几年里，自我报告的认知困难是常见的。了解老年人如何解释和回应有关其认知的问题，对于识别可能限制认知自我报告在识别AD风险方面准确性的反应偏差至关重要。认知访谈是一种系统的方法，用于检查影响个体对特定问题的回答的反应偏差的来源。本研究的目的是确定共同的认知自我报告项目的特点，有助于（a）不同的解释之间的受访者和（B）老年人的决策过程时，回答。（n = 49; M-年龄= 74.5岁; 36.7%男性）没有痴呆症完成了人口统计学问卷，蒙特利尔认知评估，和录音认知访谈。二十个常用的认知自我报告项目进行了评估，使用认知访谈技术。问题评估系统被用来指导访谈数据的分析和识别的认知自我报告items.Results内和跨响应偏差的来源：在项目解释和决策过程中的不一致性的最常见的来源是模糊的项目措辞，不正确的假设跨情况下的认知问题的一致性，和挑衅的情绪反应，影响响应。自我报告的认知评估对于促进早期AD症状的研究至关重要。这项研究的结果确定了可修改的来源的反应偏差，可能会影响目前使用的认知自我报告项目的测量属性，并可以通知细化的措施。
Background and Objectives: Self-reported cognitive difficulties are common in the years before an Alzheimer's disease (AD) diagnosis. Understanding how older adults interpret and respond to questions about their cognition is critical to recognize response biases that may limit the accuracy of cognitive self-reports in identifying AD risk. Cognitive interviewing is a systematic approach for examining sources of response bias that influence individuals' answers to specific questions. The purpose of this study was to identify features of common cognitive self-report items that contribute to (a) differing interpretations among respondents and (b) older adults' decisional processes when responding.Research Design and Methods: A convenience sample of community-dwelling older adults (n = 49; M-age = 74.5 years; 36.7% male) without dementia completed a demographic questionnaire, the Montreal Cognitive Assessment, and an audio-recorded cognitive interview. Twenty commonly used cognitive self-report items were evaluated using cognitive interviewing techniques. The Question Appraisal System was used to guide the analysis of interview data and identify sources of response bias within and across cognitive self-report items.Results: The most common sources of inconsistency in item interpretation and decisional processes were vague item wording, incorrect assumptions regarding consistency of cognitive problems across situations, and provocation of an emotional reaction that influenced responses.Discussion and Implications: Assessment of self-reported cognition is critical to facilitate research on early AD symptoms. Findings from this study identify modifiable sources of response bias that may influence the measurement properties of currently used cognitive self-report items and can inform refinement of measures.
