Previous research suggests that subjective perceptions of memory may be related to objective memory performance. In the present study, healthy community-dwelling elders (N = 73, mean age = 75.25 years, education = 16.2 years) completed a neuropsychological assessment, including two questionnaires of subjective memory beliefs. Each participant was identified, via consensus conference, as belonging to either an amnestic mild cognitive impairment (MCI, n = 16) or no mild cognitive impairment (noMCI, n = 57) group. Results indicated that subjective memory capacity beliefs were significantly related to verbal memory performance in the MCI group, but not in the noMCI group. This differential relationship persisted even after controlling for depressive symptoms, and was not reflective of unequal variances in the two groups. Thus, results indicate that subjective memory beliefs may be better indicators of performance in those with possible incipient cognitive impairment than normal older adults, perhaps because persons with MCI have heightened insight into their memory functioning, and that this relationship is not due to group differences in depressive symptoms.
先前的研究表明,对记忆的主观认知可能与客观记忆表现有关。在本研究中,健康的社区老年人(N = 73,平均年龄 = 75.25岁,受教育年限 = 16.2年)完成了一项神经心理学评估,包括两份关于主观记忆信念的问卷。通过共识会议,每位参与者被确定属于遗忘型轻度认知障碍(MCI,n = 16)组或无轻度认知障碍(noMCI,n = 57)组。结果表明,主观记忆能力信念与MCI组的言语记忆表现显著相关,但与noMCI组无关。即使在控制了抑郁症状之后,这种差异关系仍然存在,并且并非反映两组方差不等。因此,结果表明,与正常老年人相比,主观记忆信念可能是可能存在早期认知障碍者表现的更好指标,这可能是因为MCI患者对其记忆功能有更高的洞察力,并且这种关系并非由于两组抑郁症状的差异。
