轻度认知障碍对老年人幸福感的影响:自我效能的中介效应

Impact of mild cognitive impairment on elderly well-being:the mediating effect of self-efficacy

目的探讨轻度认知障碍对老年人幸福感的影响,以及自我效能感在其中发挥的中介作用,为轻度认知障碍老年人的健康管理和临床干预提供有效依据。方法2018年12月至2019年6月采用一般自我效能感量表、蒙特利尔认知评估量表和纽芬兰纪念大学幸福度量表对164名新诊断的轻度认知障碍老年人进行调查。结果轻度认知障碍老年人自我效能感总体得分为(21.41±3.98)分,主观幸福感总均分为(26.44±7.35)分。认知功能、自我效能感和主观幸福感三者之间,除自我效能感和认知功能之间相关关系不显著外,其余两两之间呈正相关(r值为0.263~0.687,P<0.01),自我效能感在轻度认知障碍对老年人主观幸福感的影响中起部分中介调节作用,占总效应的比例为37.8%。结论轻度认知障碍也会对老年人的主观幸福感造成明显的负面影响,其中自我效能感发挥着尤为重要的调节作用,自我效能感的干预在轻度认知障碍的老年人群中可能会收获更为显著的效果。

Objective To explore the effect of mild cognitive impairment on the subjective well-being of the elderly and the mediating role of self-efficacy in it.To provide an effective basis for health management and clinical intervention in the elderly with mild cognitive impairment.Methods A total of 164 patients with mild cognitive impairment from December 2018 to June 2019 were surveyed by the General Self-efficacy Scale,the Montreal Cognitive Assessment Scale,and the Memorial University of Newfoundland Scale of Happiness Scale.Results The overall score of self-efficacy was 21.41±3.98,and subjective well-being was 26.44±7.35.There was a positive correlation among cognitive function,self-efficacy and subjective well-being,except that there was no significant correlation between self-efficacy and cognitive function(r values were 0.263-0.687,P<0.01).Self-efficacy played a part in mediating between cognitive function and subjective well-being in patients with mild cognitive impairment,accounting for 37.8%of the total effect.Conclusions Mild cognitive impairment can also have a negative impact on the subjective well-being of the elderly.Among them,self-efficacy plays a particularly important role in mediating.Interventions about self-efficacy on the elderly with mild cognitive impairment may have more significant effects.
