摘　　要：目的探究成年期社会经济地位和抑郁在童年友谊经历与老年人认知功能间的中介作用。方法本文运用中国健康与养老追踪调查(CHARLS)2014、2018、2020年面板数据,运用偏相关分析法探究童年友谊经历、成年期社会经济地位、抑郁以及老年人认知功能间的相关性,使用SPSS的Process 4.1宏程序进行链式中介效应分析,并用Bootstrap法进行中介变量验证。结果童年友谊经历对老年人认知功能的直接效应显著(β=0.226,95%CI:0.109~0.343),成年期社会经济地位和抑郁在童年友谊经历和老年人认知功能间的单独中介效应显著(β=0.095,95%CI:0.067~0.126;β=0.023,95%CI:0.009~0.040),成年期社会经济地位和抑郁在童年友谊经历和老年人认知功能间的链式中介效应显著(β=0.006,95%CI:0.003~0.010),总中介效应和链式中介效应在总效应中分别占比35.33%和1.71%。结论童年友谊经历能够直接正向影响老年人认知功能,也可以通过成年期社会经济地位和抑郁的单独和链式中介作用影响老年人认知功能。Objective To explore the chain mediating roles of adult socioeconomic status and depression in the relationship between childhood friendship experiences and cognitive function in the elderly.Methods Based on the panel data of China Health and Retirement Tracking Survey(CHARLS)in 2014,2018,and 2020,Partial correlation analysis was used to explore the correlation among childhood friendship experience,adult socioeconomic status,depression,and cognitive function of the elderly.The SPSS’s Process 4.1macro program was used to analyze the chain mediation effect,and Bootstrap method was used to verify the mediation variables.Results The direct effect of childhood friendship experiences on cognitive function in the elderly was significant(β=0.226,95%CI:0.109-0.343).The simple mediating effects of adult socioeconomic status and depression between childhood friendship experiences and cognitive function were significant(β=0.095,95%CI:0.067-0.126;β=0.023,95%CI:0.009-0.040).The chain mediating effect of adult socioeconomic status and depression between childhood friendship experiences and cognitive function was significant(β=0.006,95%CI:0.003-0.010).The total mediating effect and the chain mediating effect respectively account for 35.33%and 1.71%of the total effect.Conclusion Childhood friendship experience can directly and positively influence cognitive function in the elderly,and also can influence cognitive function in the elderly through the separate and chain mediating effects of socioeconomic status and depression in adulthood.
