先前的研究表明，对记忆的主观感知可能与客观记忆表现有关。在本研究中，健康的社区居住老年人（N = 73，平均年龄= 75.25岁，受教育程度= 16.2年）完成了一项神经心理评估，包括主观记忆信念问卷。通过共识会议，每个参与者被确定为属于健忘轻度认知障碍（MCI, n = 16）或无轻度认知障碍（noMCI, n = 57）组。结果表明，主观记忆容量信念在MCI组与言语记忆表现显著相关，而在noMCI组无显著相关。即使在控制抑郁症状后，这种差异关系仍然存在，并没有反映出两组中不相等的差异。因此，结果表明，主观记忆信念可能是那些可能有早期认知障碍的老年人比正常老年人更好的表现指标，这可能是因为轻度认知障碍患者对他们的记忆功能有更高的洞察力，而这种关系不是由于抑郁症状的组差异。
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.
