摘要
两种记忆状况组来自于参与加拿大维多利亚纵向研究(VLS)的老年人原样本。一种是未受损伤的控制组(NIC),另一种是轻度记忆损伤组(MMD)。在基线水平和纵向水平上(即5次追踪或12年)比较了他们在日常生活中对记忆补偿技术的使用。我们使用多水平模型(以年龄和教育水平为协变量)来检验基线水平的差异和长期的变化模式。基线的结果表明MMD组被试报告了近期在日常生活中使用记忆补偿策略方面有更大的增长。纵向的结果表明记忆补偿的使用在12年中具有明显的稳定性,但是与努力相关的补偿机制存在显著组间差异。教育水平这一协变量(可认为是潜在的认知储备指标)和三种记忆补偿策略随时间的不同变化相关。
Two memory status groups were derived from a parent sample of older adults participating in the Victoria Longitudinal Study （VLS） in Canada. A not impaired control （NIC） group and a mild memory deficit （MMD） group were compared at baseline and longitudinally （over five waves or 12 years） regarding their use of memory compensation techniques in everyday life. We used multi-level modeling （covarying age and education） to examine baseline level differences and long-term change patterns. Baseline results showed that the MMD participants reported greater recent increases in memory compensation strategy use in everyday life. Longitudinal results showed notable 12-year stability in memory compensation use, but group-related differences in the compensatory mechanism of effort. The covariate of education （potentially a marker of cognitive reserve） was associated with differential change in three memory compensation strategies over time.
