This study examined the association between bereavement and cross-sectional differences in cognitive performance in a sample of older adults.
Secondary cross-sectional data analysis was conducted on 211 participants from the MacArthur Battery dataset. Participants completed several cognitive tasks 6-months post-loss.
Hierarchical multiple regression results suggested that bereavement status was not associated with cognitive performance. However, the effect of bereavement on memory (immediate and delayed story recall) performance was moderated by age and gender where the younger participants and men who were bereaved performed worse compared to their non-bereaved counterparts.
Our results support the finding that bereavement is associated with poorer memory performance within certain subgroups (i.e., men and younger participants). We discuss findings in light of theories of stress and cognitive aging.
本研究考察了在老年人群体样本中，丧亲与认知表现的横断面差异之间的关系。
对来自麦克阿瑟电池数据集的 211 名参与者进行了二次横断面数据分析。参与者在失去亲人后 6 个月内完成了几项认知任务。
分层多元回归结果表明，丧亲状态与认知表现无关。然而，丧亲对记忆（即时和延迟故事回忆）表现的影响受到年龄和性别因素的调节，即丧亲的年轻参与者和男性表现不如未丧亲的参与者。
我们的结果支持了这样一种观点，即丧亲与某些亚组（即男性和年轻参与者）的较差记忆表现有关。我们根据应激和认知老化理论讨论了研究结果。
