BACKGROUND
The study aim was to determine if state and trait intra-individual measures of everyday affect predict cognitive functioning in healthy older community dwelling European adults (n = 387), aged 55-87 years.
METHODS
Participants were recruited from centres in France, Italy and Northern Ireland. Trait level and variability in positive and negative affect (PA and NA) were assessed using self-administered PANAS scales, four times a day for four days. State mood was assessed by one PANAS scale prior to assessment of recognition memory, spatial working memory, reaction time and sustained attention using the CANTAB computerized test battery.
RESULTS
A series of hierarchical regression analyses were carried out, one for each measure of cognitive function as the dependent variable, and socio-demographic variables (age, sex and social class), state and trait mood measures as the predictors. State PA and NA were both predictive of spatial working memory prior to looking at the contribution of trait mood. Trait PA and its variability were predictive of sustained attention. In the final step of the regression analyses, trait PA variability predicted greater sustained attention, whereas state NA predicted fewer spatial working memory errors, accounting for a very small percentage of the variance (1-2%) in the respective tests.
CONCLUSION
Moods, by and large, have a small transient effect on cognition in this older sample.
背景
本研究旨在确定个体日常情感的状态和特质内测量是否能预测健康的老年社区居住欧洲成年人（n=387，年龄 55-87 岁）的认知功能。
方法
参与者从法国、意大利和北爱尔兰的中心招募。使用自我管理的 PANAS 量表，每天四次，持续四天，评估正性和负性情感（PA 和 NA）的特质水平和变异性。在使用 CANTAB 计算机化测试电池评估识别记忆、空间工作记忆、反应时间和持续注意力之前，通过一个 PANAS 量表评估状态情绪。
结果
对认知功能的每一个测量结果（作为因变量）进行了一系列层次回归分析，并将社会人口统计学变量（年龄、性别和社会阶层）、状态和特质情绪测量结果作为预测因子。在考虑特质情绪贡献之前，状态 PA 和 NA 都可以预测空间工作记忆。在回归分析的最后一步，特质 PA 的变异性预测了更好的持续注意力，而状态 NA 则预测了较少的空间工作记忆错误，在各自的测试中仅占很小的比例（1-2%）。
结论
在这个老年样本中，情绪在很大程度上对认知有短暂的影响。
