目的：我们试图研究抑郁症状和主观记忆问题之间的关系。我们假设抑郁症状和较差的主观记忆功能之间的关系是由与绝望、死亡愿望和低自尊相关的负面认知偏见介导的。方法：299名有或无明显抑郁症状的老年人的完整数据，这些老年人在初级保健办公室接受了筛查，并被邀请参加，完成了基线在家评估。主观记忆功能和心理状态评估常用的，有效的标准问卷。结果：在包含年龄、性别和认知测量的回归模型中，抑郁症状与整体记忆自我评估呈显著负相关（beta = -0.019; p = 0.006）。当模型中包含消极认知偏差的成分（绝望、低自尊、想死）时，抑郁症状与主观记忆问题的关系减弱，与中介一致。结论：我们的研究结果表明，评估和成功干预非痴呆老年人的记忆抱怨需要考虑负面认知偏差和抑郁症状。在假设中介关系之前，需要进行纵向研究来证实我们的发现。
Objectives: We sought to examine the relationship between depressive symptoms and subjective memory problems. We hypothesized that the relationship between depressive symptoms and poor subjective memory functioning is mediated by negative cognitive bias that is associated with hopelessness, a wish to die and low self-esteem.Methods: Complete data were available for 299 older adults with and without significant depressive symptoms who were screened in primary care offices and invited to participate, completed a baseline in-home assessment. Subjective memory functioning and psychological status was assessed with commonly used, validated standard questionnaires.Results: In regression models that included terms for age, gender and cognitive measures, depressive symptoms were significantly inversely associated with the global self-assessment of memory ( beta = -0.019; p = 0.006). When components of negative cognitive bias were included in the model (hopelessness, low self-esteem, a wish to die), the relationship of depressive symptoms with subjective memory problems was attenuated, consistent with mediation.Conclusions: Our results suggest that assessment and successful interventions for memory complaints in non-demented older adults need to account for negative cognitive bias as well as depressive symptoms. Longitudinal research is needed to confirm our findings before a mediator relationship can be presumed.
