大学生儿童期创伤和抑郁情绪对分裂型人格特质与执行功能的影响

探讨儿童期创伤和抑郁情绪对分裂人格特质与执行功能关系的影响,为有效改善儿童心理健康提供参考.方法 在湖南中医药大学和衡阳师范学院方便抽取2 469名学生,使用儿童创伤问卷(CTQ)筛选有儿童期创伤史的学生.随机抽取63名有儿童期创伤史的学生和93名无创伤史学生.使用Chapman分裂型人格倾向量表、抑郁自评量表(SDS)和成人版执行功能行为评定量表(BRIEF-A)测量学生心理及行为特征.结果 行为管理指数与情感虐待、躯体虐待、情感忽视、躯体忽视、阳性分裂型特质、阴性分裂型特质和抑郁情绪均呈正相关(r=0.162~0.511,P值均<0.05).元认知指数与情感虐待、躯体忽视、阳性分裂型特质、阴性分裂型特质和抑郁情绪均呈正相关(r=0.180~ 0.386,P值均<0.05).回归分析结果显示,当同时纳入分裂人格特质、儿童期创伤和抑郁变量时,仅阳性分裂型特质和抑郁情绪对行为管理指数(β值分别为0.306,0.329,P值均<0.05)和元认知指数起到预测作用(β值分别为0.209,0.239,P值均<0.05),而所有的儿童期创伤变量对执行功能均无预测作用(P值均>0.05).进一步的中介分析发现,抑郁情绪在阳性分裂型特质和执行功能之间起部分中介作用.结论 分裂人格的阳性特质和抑郁情绪影响了执行功能.

Influence of childhood trauma and depression on schizotypy and performing fuction among college students

Objective To explore the influence of childhood trauma and depression on schizotypy and executive function,and to provide references for effectively improving the mental health among children.Methods Childhood trauma questionnaireshort form was applied to select 2 469 college students from Hunan university of Chinese medicine and Hengyang Normal College.Among the subjects,63 children with trauma was selected as abused group and 93 ones were taken as control group.What's more,they were asked to fill in four Chapman Psychosis Proneness Scales (CPPS),Self-Rating Depression Scale(SDS) and the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A).Results Behavioral regulation index (BRI) and emotional abuse,physical abuse,emotional neglect,physical neglect,positive schizotypy,negative schizotypy and depression were positively correlated with depression(r=0.162-0.511,P<0.05);Metacognition index (MI) was positively related with emotional abuse,physical neglect,positive schizotypy,negative schizotypy and depression (r=0.180-0.386,P<0.05).In the prediction model of executive function,emotional abuse,positive schizotypy and depression had a significant predictive effect on BRI(β =0.306,0.329,P< 0.05) and MI (β=0.209,0.239,P<0.05),while all types of childhood trauma had no predictive effect on executive function(P> 0.05).Path analysis revealed that depression was the mediator between positive schizotypy and executive function.Conclusion Positive schizotypy and depression have influenced executive function.
