山东省某高校大学生心理资本和轻躁狂人格在儿童期创伤与睡眠质量关系中的多重中介作用

目的探究山东省某高校大学生儿童期创伤、心理资本、轻躁狂人格与睡眠质量的关系。方法2017年4-5月,选取山东省某高校651名大学生,采用儿童期创伤问卷简化版(CTQ-SF)、青少年心理资本问卷(PCQAS)、轻躁狂人格量表(Hyp)、匹兹堡睡眠质量指数(PSQI)与一般人口学问卷分别测量被试的儿童期创伤、心理资本、轻躁狂人格、睡眠质量与一般人口学变量。结果(1)儿童期创伤得分与轻躁狂人格及睡眠质量指数得分均呈正相关(r=0.20,0.21,均P<0.01),而与心理资本呈负相关(r=-0.31,P<0.01)。心理资本得分与轻躁狂人格及睡眠质量指数得分均呈负相关(r=-0.18,-0.20,均P<0.01);轻躁狂得分与睡眠质量指数得分呈正相关(r=0.18,P<0.01)。(2)结构方程模型拟合良好,χ^2/df=3.813<5,近似误差均方根(RMSEA)、规范拟合指数(NFI)、Tucker-Lewis指数(TLI)与比较拟合指数(CFI)分别为0.064、0.935、0.918和0.950;引入心理资本和轻躁狂人格两个中介变量后,Bootstrap检验显示儿童期创伤对睡眠质量的多重中介效应95%CI为0.005~0.021,区间不包括0,提示心理资本、轻躁狂人格在儿童期创伤和睡眠质量之间发挥多重中介效应。结论山东省某高校大学生儿童期创伤程度越严重,心理资本水平越低,轻躁狂人格就会越明显,睡眠质量也越差。

Multiple mediating effect of psychological capital and hypomanic personality on relationship between childhood trauma and sleep quality among students in a university in Shandong Province

Objective]To investigate the relationships among childhood trauma,psychological capital,hypomanic personality,and sleep quality among students in a university in Shandong Province.Methods]From April to May 2017,a total of 651 students were selected from a university in Shandong Province.Their childhood traumas,psychological capital,hypomanic personality,sleep quality and socio-demographic variables were assessed by the Childhood Trauma Questionnaire-Short Form(CTQ-SF),the Psychological Capital Questionnaire for Adolescent Students scale(PCQAS),the Hypomanic Personality Scale(Hyp),the Pittsburgh Sleep Quality Index(PSQI)and the Socio-demographic Questionnaire.Results]①The total score of CTQ-SF was significantly and positively related to total score of Hyp and PSQI(r=0.20,0.21,both P<0.01),while was significantly and negatively correlated with total score of PCQAS(r=-0.31,P<0.01).The total score of PCQAS was significantly and negatively related to total score of Hyp and PSQI(r=-0.18,-0.20,both P<0.01).The total score of Hyp was significantly and positively correlated with total score of PSQI(r=0.18,P<0.01).②The structural equation was modeled well,χ^2/df=3.813<5.Root mean square error approximation RMSEA(RMSEA),normative fitting index(NFI),Tucker-Lewis index(TLI)and comparative fitting index(CFI)was 0.064,0.935,0.918 and 0.950 respectively.After introducing psychological capital and hypomanic personality as mediators,the Bootstrap test showed a concurrent multiple mediating effect of childhood trauma to sleep quality,with a confidence interval of 95%for 0.005-0.021,interval did not include 0.The results showed that the psychological capital and hypomanic personality played multiple mediating effects between childhood trauma and sleep quality.Conclusion]The more serious the childhood trauma and the lower the level of psychological capital,the more obvious the hypomanic personality and the worse the sleep quality of college students in Shandong Province.
