Affect and cognition have both been associated with communication across one's social network during ageing. Thus, it is important to consider how communication varies by different aspects of one's social network, and by communication mode, including phone, email and social media. This study aimed to investigate the relationship between technology-mediated communication, depression and an executive function-related fluid-reasoning measure among older adults. Data were drawn from the Health and Retirement dataset's 2016 wave. Hierarchical regression analyses were conducted to examine the link between communication modes (phone, email and social media) with children, family and friends with a fluid-reasoning cognition measure and Center for Epidemiologic Studies Depression Scale, controlling for demographic covariates, among 3,798 older American adults. Phone and email communication, but not social media, were significantly related to depression and cognition. The model fit was considerably stronger for the analyses with cognition than depression. Curvilinear associations were found for communication via phone and email with cognition, suggesting moderate amounts of communication by phone and email across social groups were most closely linked with higher scores on fluid reasoning. For depression, curvilinear relationships were found for talking on the phone with family and friends, and emailing for children and family, indicating that moderate communication levels revealed the lowest depression levels. Implications for how older adults’ social support may contribute to depression and cognition status are discussed.

情感和认知都与衰老过程中跨社交网络的交流有关。因此，重要的是要考虑通信如何根据一个人的社交网络的不同方面以及通信模式（包括电话，电子邮件和社交媒体）而变化。这项研究旨在调查老年人之间技术介导的沟通，抑郁与执行功能相关的体液量度措施之间的关系。数据摘自健康与退休数据集的2016年一波。进行了层次回归分析，以流体推理方式和儿童流行病学研究中心抑郁量表（控制人口统计学协变量）检验了与儿童，家人和朋友之间的沟通模式（电话，电子邮件和社交媒体）之间的联系，798个美国老年人。电话和电子邮件通信（而非社交媒体）与抑郁和认知密切相关。对于认知分析，模型拟合明显强于抑郁。发现曲线联系可以通过电话和电子邮件进行认知交流，这表明跨社会群体通过电话和电子邮件进行的适度交流与流畅推理得分较高密切相关。对于抑郁症，发现了曲线关系，可以与家人和朋友通电话，向孩子和家人发送电子邮件，这表明适度的交流水平显示出最低的抑郁症水平。讨论了老年人的社会支持如何可能导致抑郁和认知状态的暗示。但社交媒体却没有，与抑郁和认知密切相关。对于认知分析，模型拟合明显强于抑郁。发现曲线联系可以通过电话和电子邮件进行认知交流，这表明跨社会群体通过电话和电子邮件进行的适度交流与流畅推理得分较高密切相关。对于抑郁症，发现了曲线关系，可以与家人和朋友通电话，向孩子和家人发送电子邮件，这表明适度的交流水平显示出最低的抑郁症水平。讨论了老年人的社会支持如何可能导致抑郁和认知状态的暗示。但社交媒体却没有，与抑郁和认知密切相关。对于认知分析，模型拟合明显强于抑郁。发现曲线联系可以通过电话和电子邮件进行认知交流，这表明跨社会群体通过电话和电子邮件进行的适度交流与流畅推理得分较高密切相关。对于抑郁症，发现了曲线关系，可以与家人和朋友通电话，向孩子和家人发送电子邮件，这表明适度的交流水平显示出最低的抑郁症水平。讨论了老年人的社会支持如何可能导致抑郁和认知状态的暗示。对于认知分析，模型拟合明显强于抑郁。发现曲线联系可以通过电话和电子邮件进行认知交流，这表明跨社会群体通过电话和电子邮件进行的适度交流与流畅推理得分较高密切相关。对于抑郁症，发现了曲线关系，可以与家人和朋友通电话，向孩子和家人发送电子邮件，这表明适度的交流水平显示出最低的抑郁症水平。讨论了老年人的社会支持如何可能导致抑郁和认知状态的暗示。对于认知分析，模型拟合明显强于抑郁。发现曲线联系可以通过电话和电子邮件进行认知交流，这表明跨社会群体通过电话和电子邮件进行的适度交流与流畅推理得分较高密切相关。对于抑郁症，发现了曲线关系，可以与家人和朋友通电话，向孩子和家人发送电子邮件，这表明适度的交流水平显示出最低的抑郁症水平。讨论了老年人的社会支持如何可能导致抑郁和认知状态的暗示。这表明在社会群体之间通过电话和电子邮件进行的适度交流与流动性推理得分较高密切相关。对于抑郁症，发现了曲线关系，可以与家人和朋友通电话，向孩子和家人发送电子邮件，这表明适度的交流水平显示出最低的抑郁症水平。讨论了老年人的社会支持如何可能导致抑郁和认知状态的暗示。这表明在社会群体之间通过电话和电子邮件进行的适度交流与流动性推理得分较高密切相关。对于抑郁症，发现了曲线关系，可以与家人和朋友通电话，向孩子和家人发送电子邮件，这表明适度的交流水平显示出最低的抑郁症水平。讨论了老年人的社会支持如何可能导致抑郁和认知状态的暗示。
