强迫症患者梦威胁模拟水平与童年创伤生活事件的关系

Relationship among the dream threat level, life events and childhood trauma in obsessive-compulsive patients

目的探讨强迫症患者梦的威胁模拟水平及其与童年创伤和生活事件的关系。方法对59例强迫症患者和57例正常对照者采用梦威胁事件问卷（DTQ）进行梦威胁模拟水平的调查，并作童年创伤问卷（CTQ）和生活事件量表（LES）评估，分析童年创伤、生活事件与梦威胁模拟水平的关系。结果患者组DTQ分[（3．31±3．04）分]、CTQ总分[（43．02±10．78）分]和LES总分[145．39±46．01）分]及其负性生活事件分[（39．56±42．94）分]明显高于对照组[分别为：（1．d0±2．23）分、（34．21±8．47）分、（16．88±16．42）分和（14．14±14．61）分，P〈0．01]；相关分析显示，患者CTQ、LES和DTQ得分之间均两两显著相关（r=0．326～0．402，P〈0．05—0．01）；回归分析发现，童年创伤可直接预测梦威胁模拟水平（β=0．104，P〈0．05），在负性生活事件与梦的威胁模拟水平的关系中起着完全中介作用。结论强迫症患者梦威胁模拟水平增高，与童年创伤和生活事件存在相关，童年创伤在生活事件与梦威胁模拟水平的关系中具有完全中介效应。

Objective To explore the relationship among dream threat level, life events and childhood trauma in obsessive-compulsive patients. Methods 59 obsessive-compulsive patients and 57 healthy controls were tested with Dream Threat Questionnaire （DTQ） , Childhood Trauma Questionnaire （CTQ） and Life Events Scale （LES）. The dream threat level were compared between the two groups, and correlation and regression analysis were used to research the relationship of the variables for patients data. Results Compared with the healthy controis,patients had significantly higher DTQ score （ 1.40 ±2.23 vs 3.31 ± 3.04, P 〈 0.01 ）, CTQ total score （34.21± 8.47 vs 43.02± 10.78, P 〈 0.01 ）, LES total score （ 16.88 ±16.42 vs 45.39 ±46.01, P 〈 0.01 ） and its negtive life events subseore （ 14.14 ±14.61 vs 39.56 ± 42.94, P 〈 0.01 ）. Correlation analysis showed that dream threat level, negative life events and childhood trauma were significantly positively correlated each other（ r = 0. 326 ±0. 402, P〈0.05 - 0.01 ）. Regression analysis indicated that childhood trauma directly predicted dream threat level （β= 0. 104, P 〈0.05 ） and completely mediated the relationship between negative life even~：s and dream threat level. Conclusion Obsessive-compulsive patients have higher dream threat level, more childhood trauma experience and life events. Childhood trauma experience is a significant factor influencing dream threat level, and as a complete mediation by which life events influence dream threat level.
