The Relationship between Childhood Psychological Maltreatment and Trait Depression:a Chain Mediating Effect of Rumination and Post-traumatic Cognitive Changes

目的:探讨反刍思维和创伤后认知改变在儿童期心理虐待和特质抑郁间的中介作用。方法:使用儿童期心理虐待量表、状态特质抑郁问卷(STDEP)、反刍思维量表(RRS)和创伤后认知改变问卷(PCC)测量大学生的儿童期心理虐待、抑郁、反刍思维和创伤后认知改变情况,使用Mplus7.0建立中介作用模型。结果:反刍思维和创伤后认知改变分别在心理虐待和特质抑郁间起中介作用;反刍思维和创伤后认知改变在心理虐待和特质抑郁间起链式中介作用。间接效应效果量为52.8%,其中通过创伤后认知改变这一中介变量的效果量最大,达39.6%。结论:儿童期心理虐待可分别通过反刍思维和创伤后认知改变影响特质抑郁;心理虐待也通过反刍思维影响创伤后认知改变,进而影响特质抑郁。
