This exploratory study examined the moderating effects of personality traits on cognitive function following a cognitively stimulating individualized activity intervention delivered to individuals at high risk for cognitive decline: those with delirium superimposed on dementia. Data were taken from an ongoing randomized clinical trial with the addition of a personality measure. The results for 71 participants randomized to intervention or control groups are reported. Significant moderating effects of personality traits were found such that participants with higher agreeableness were more likely to have improved delayed recall and those with lower extraversion were more likely to have improved executive function, as a result of the intervention. Lower openness, higher agreeableness, and lower conscientiousness were associated with greater engagement in the intervention. A cognitive stimulation intervention for older adults at high risk for further cognitive decline may be differentially effective based on certain personality traits.
这项探索性研究考察了性格特质对认知功能的调节作用，该研究针对认知功能衰退高危个体（即患有痴呆症合并谵妄的个体）开展了一项认知刺激个性化活动干预。数据取自一项正在进行的随机临床试验，并增加了一项性格测量。报告了随机分为干预组或对照组的71名参与者的结果。研究发现性格特质具有显著的调节作用，即干预后，宜人性较高的参与者延迟回忆改善的可能性更大，外向性较低的参与者执行功能改善的可能性更大。开放性较低、宜人性较高和尽责性较低与干预参与度较高相关。基于某些性格特质，针对认知功能进一步衰退高危老年人的认知刺激干预可能具有不同的效果。
