We examine the association between subjective cognitive decline (SCD) and the trajectories of objective cognitive decline (OCD); and the extent to which this association is moderated by social relationships.
Data come from waves 10 (2010) through 14 (2018) of the Health and Retirement Study, a nationally representative panel survey of individuals aged 50 and above in the United States. OCD is measured using episodic memory, and overall cognition. SCD is assessed using a baseline measure of self-rated memory. Social relationships are measured by social network size and perceived positive and negative social support. Growth curve models estimate the longitudinal link between SCD and subsequent OCD trajectories and the interactions between SCD and social relationship variables on OCD.
SCD is associated with subsequent OCD. A wider social network and lower perceived negative support are linked to slower decline in memory, and overall cognition. None of the social relationship variables, however, moderate the link between SCD and future OCD.
Knowing that SCD is linked to subsequent OCD is useful because at SCD stage, deficits are more manageable relative to those at subsequent stages of OCD. Future work on SCD and OCD should consider additional dimensions of social relationships.
我们研究了主观认知衰退（SCD）与客观认知衰退（OCD）轨迹之间的关联；以及这种关联在多大程度上受到社会关系的调节。
数据来自美国健康与退休研究的第 10 波（2010 年）至第 14 波（2018 年），这是一项针对 50 岁及以上人群的全国代表性面板调查。OCD 使用情景记忆和整体认知来衡量。SCD 使用自我评估记忆的基线测量来评估。社会关系通过社交网络规模以及感知到的积极和消极社会支持来衡量。增长曲线模型估计了 SCD 与随后的 OCD 轨迹之间的纵向联系，以及 SCD 与 OCD 变量之间的相互作用。
SCD 与随后的 OCD 相关。更大的社交网络和较低的感知负面支持与记忆和整体认知的下降速度较慢有关。然而，社会关系变量中没有一个可以调节 SCD 与未来 OCD 之间的联系。
了解 SCD 与随后的 OCD 有关是有用的，因为在 SCD 阶段，与 OCD 后期阶段相比，缺陷更容易控制。未来关于 SCD 和 OCD 的研究应该考虑社会关系的其他维度。
