摘　　要：目的:比较青少年抑郁症患者与正常青少年在主动遗忘能力上的差异,并探讨该能力与童年创伤和抑郁症状的关系。方法:符合精神障碍诊断与统计手册第5版(DSM-5)抑郁症诊断标准的141例青少年患者和42例正常对照组参与研究。采用定向遗忘(DF)任务,以情绪图片为记忆材料,比较两组在再认成绩上的差异。DF效应指“记住”条件再认成绩高于“忘记”条件。并采用儿童期创伤问卷(CTQ-SF)和贝克抑郁量表(BDI-II)评估被试的童年创伤程度和抑郁症状。结果:与正常对照组不同,抑郁症组仅在正性材料中出现DF效应(P<0.001)。在抑郁症组中,负性材料DF效应值在CTQ-SF得分与BDI-II得分间起部分中介作用(效应值=0.10,95%可信区间为0.05~0.17,占总效应21.3%)。结论:青少年抑郁症患者的主动遗忘能力部分受损,他们对负性记忆的主动遗忘能力在童年创伤与抑郁症状间有部分中介效应。Objective:To compare the motivated forgetting ability between adolescents with depression and normal adolescents and to explore the relationship of this ability with childhood trauma and symptoms of depression.Methods:Totally 141 adolescents diagnosed with depression according to the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5),and 42 normal controls participated in the study.The directed forgetting(DF)task was employed,using emotional images as memory stimuli,to compare the recognition performance between the two groups.The presence of the DF effect was identified when the recognition score under the"to-be-remembered"condition was significantly higher than the"to-be-forgot ten"condition.The Childhood Trauma Questionnaire Short Form(CTQ-SF)and Beck Depression Inventory-II(BDI-II)were utilized to assess the severity of participants'childhood trauma and depression symptoms.Results:Unlike the control group,the adolescents with depression only exhibited the DF effect with positive stimuli(P<0.001).In the depression group,the DF effect value for negative stimuli partially mediated the relationship between CTQ-SF scores and BDI-II scores(effect size=0.10,95%confidence interval 0.05-0.17,accounting for 21.3%of the total effect).Conclusion:The motivated forgetting ability is partially impaired in adolescents with depressioa The ability,especially regarding negative memories,plays a partial mediating role between childhood trauma and depressive symptoms in adolescents with depression.
