An increasing number of studies have documented the cognitive profile of individuals with mild cognitive impairment (MCI), but few studies have investigated the individuals' psychological health and personality traits or how these factors interact with cognition. In the present study, 27 healthy older adults and 30 persons with MCI completed questionnaires covering psychological health, morale, personality, self-efficacy, and self-actualization. The results indicated that individuals with MCI are more depressed, anxious, hostile, and have lower morale than matched healthy older adults. Furthermore, our results show a positive association between the level of depression of MCI persons and the severity of their cognitive dysfunctions. In contrast, there were no group differences on measures of personality traits. Thus, while psychological distress is present in persons with MCI, those individuals are not characterized by differences in personality traits relative to older adults who experience no cognitive impairment.
越来越多的研究记录了轻度认知障碍（MCI）个体的认知特征，但很少有研究调查个体的心理健康和人格特质，或这些因素如何与认知相互作用。在本研究中，27 名健康老年人和 30 名 MCI 患者完成了涵盖心理健康、士气、人格、自我效能和自我实现的问卷。结果表明，MCI 患者比匹配的健康老年人更抑郁、焦虑、敌对，士气更低。此外，我们的结果表明，MCI 患者的抑郁程度与认知功能障碍的严重程度呈正相关。相比之下，人格特质的测量没有组间差异。因此，虽然 MCI 患者存在心理困扰，但与没有认知障碍的老年人相比，这些个体的人格特质没有差异。
