Previous research on older adults' information and communication technology (ICT) use has shown that cognitive function is linked with ICT use; however, the direction of influence has been yet to be determined. The current study examined the temporal sequence of ICT use and cognitive performance. Using three waves (2013, 2015, and 2017) from the National Health and Aging Trends Study, a total of 3,904 community-dwelling older adults aged 65 and above were selected for the analysis. Two cognitive domains were considered: episodic memory and executive function. Reciprocal 4-year lagged associations between ICT use and each cognitive domain were examined, controlling for covariates (age, gender, education, race/ethnicity, and depression). Greater use of ICT was significantly associated with memory performance, () = .19 (.01), < .001, and executive function, () = .26 (.01), < .001, in following years. Reciprocally, episodic memory predicted ICT use, () = .02 (.01), < .001, 2 years later. However, the cross-lagged effect of executive functioning on ICT use was not significant, () = .00 (.01), = .14. These results suggest the direction of the association between ICT use and cognitive performance might vary depending on the cognitive domain.
先前关于老年人信息通信技术（ICT）使用情况的研究表明，认知功能与ICT使用有关联；然而，影响的方向尚未确定。当前的研究考察了ICT使用和认知表现的时间顺序。利用来自国家健康与老龄化趋势研究的三个时间点（2013年、2015年和2017年）的数据，总共选取了3904名65岁及以上的社区居住老年人进行分析。研究考虑了两个认知领域：情景记忆和执行功能。在控制了协变量（年龄、性别、教育程度、种族/民族和抑郁情况）之后，考察了ICT使用与每个认知领域之间的4年相互滞后关联。在随后几年中，更多地使用ICT与记忆表现显著相关，（β）=0.19（0.01），p<0.001，与执行功能也显著相关，（β）=0.26（0.01），p<0.001。相反，情景记忆在两年后预测了ICT使用情况，（β）=0.02（0.01），p<0.001。然而，执行功能对ICT使用的交叉滞后效应并不显著，（β）=0.00（0.01），p=0.14。这些结果表明，ICT使用与认知表现之间关联的方向可能因认知领域而异。
