Positive Cognition Moderate the Relationship between Posttraumatic Stress Disorder on Sleep Problems among Children Survivors after Wenchuan Earthquake

Abstract

Abstract: To examine the relationships among posttraumatic stress disorder(PTSD), positive cognition and sleep problems, the present investigated 844 pupils 30 months after Wenchuan earthquake by using Traumatic Exposure Questionnaire, Revised Child PTSD Symptom Scale, Coping Style Inventory and Child Behavior Problems Questionnaire. After the degree of traumatic expose, the results found that the global PTSD and it's specific symptom clusters have significantly positive effect on sleep problems, and the positive cognition have no significant predictive effect on sleep problems. In addition, the results also suggest that positive cognition don't moderate the relationship between intrusive symptoms of PTSD and sleep problems as well as hyperarousal symptoms of PTSD and sleep problems, but the positive cognition moderate the global PTSD and it's avoidance symptoms. Specifically speaking, comparative to individual with high positive cognition, the global PTSD and it's avoidance symptoms have stronger predictive utility for sleep problems among the individual with fewer positive cognition.

摘要： 本研究采用创伤暴露程度问卷、儿童创伤后应激障碍症状量表、应对方式问卷和儿童行为问题核查表对汶川地震30个月后844名小学生进行调查，探讨汶川地震后小学生的创伤后应激障碍（PTSD）、积极认知与睡眠问题之间的关系。结果表明，PTSD对睡眠问题具有正向预测作用，积极认知对睡眠问题的预测作用不显著。调节效应的检验结果发现，积极认知调节着PTSD及其回避性症状对睡眠问题的影响，具体表现为PTSD及其回避性症状对睡眠问题的预测作用随着积极认知水平的增加而降低，但是积极认知分别在PTSD的闯入性症状和警觉性增高症状与睡眠问题的关系之间不起调节作用。
