AIMS
We investigated whether the longitudinal relation between memory complaints and subsequent decline in executive functioning over 6 years differed by leisure activity engagement as major contributor to cognitive reserve in old age.
METHODS
We analyzed longitudinal data from 897 older adults (M = 74.33 years) tested on the Trail Making Test (TMT) in two waves 6 years apart. Participants reported information on memory complaints and leisure activity engagement.
RESULTS
There was a significant interaction of memory complaints with leisure activity engagement on latent change in executive functioning. Specifically, only for individuals with less (but not those with greater) leisure activity engagement, memory complaints significantly predicted a steeper subsequent decline in executive functioning across 6 years (i.e., increases in TMT completion time).
CONCLUSION
The role of memory complaints as an early predictor of decline in executive functioning seems to vary by individuals' cognitive reserve.
目的
我们研究了作为老年认知储备主要贡献因素的休闲活动参与情况，是否会使记忆障碍与随后6年执行功能衰退之间的纵向关系有所不同。
方法
我们分析了897名老年人（平均年龄74.33岁）的纵向数据，这些老年人在相隔6年的两个时间点接受了连线测验（TMT）。参与者报告了有关记忆障碍和休闲活动参与情况的信息。
结果
在执行功能的潜在变化方面，记忆障碍与休闲活动参与之间存在显著的交互作用。具体而言，仅对于休闲活动参与较少（而非较多）的个体，记忆障碍显著预测了随后6年执行功能更急剧的衰退（即TMT完成时间增加）。
结论
记忆障碍作为执行功能衰退早期预测指标的作用，似乎因个体的认知储备而异。
