Memory complaints are a key diagnostic criterion for dementia and mild cognitive impairment. Rating scales can be used to capture information about individuals' memory problems from informants such as family members. However, problems with scale reliability suggest that individual differences influence the ratings informants provide. This project tested whether informants' neuroticism was associated with their ratings of an older adult's memory. In an online study, 293 volunteers completed a Five-Factor Personality Questionnaire and used 2 memory questionnaires to provide ratings of memory problems in an older individual they knew well. Rater neuroticism correlated positively with estimates of memory problems: More neurotic informants provided higher estimates of memory difficulties in the person they were rating. A second study replicated this finding with 786 volunteers and another widely used memory measure, the AD8. In both studies, exploratory analyses suggested the effect size was large enough to impact on clinical practice.
记忆主诉是痴呆症和轻度认知障碍的一个关键诊断标准。评定量表可用于从家属等知情人处获取有关个体记忆问题的信息。然而，量表可靠性存在问题表明，个体差异会影响知情人提供的评定。本项目测试了知情人的神经质是否与他们对老年个体记忆的评定有关。在一项在线研究中，293 名志愿者完成了五因素人格问卷，并使用 2 个记忆问卷对他们熟悉的老年个体的记忆问题进行评定。评定者的神经质与记忆问题的评定呈正相关：更神经质的知情人对他们评定的人的记忆困难提供了更高的评定。第二项研究使用 786 名志愿者和另一个广泛使用的记忆测试（AD8）重复了这一发现。在这两项研究中，探索性分析表明，该效应大小足以对临床实践产生影响。
