C类人格障碍倾向大学生的自尊异质性研究

Heterogeneity of Self-Esteem in College Students with Symptom of Cluster-C Personality Disorders

目的:探讨C类人格障碍倾向大学生的自尊异质性及其对C类人格障碍检出的预测作用。方法:通过人格障碍筛查问卷(PDQC-2)从深圳某大学820名本科生中筛查单一无共型的C类人格障碍倾向个体,同时采用Rosen-berg自尊量表(RSES)、社会期望量表(MCSD)、不稳定自尊量表(ISES)、条件自尊量表(CSES)测量其各型自尊。结果:①与对照组相比,OBC组在条件自尊和不稳定自尊上有显著差异(P<0.05),DEP组与AVD组在各型自尊上均有显著差异(P<0.05);②C类人格障碍三组之间在条件自尊得分上无显著差异,OBC组在外显自尊及防御性上得分最高,AVD组最低(P<0.05);在不稳定自尊得分上,OBC组最低,AVD组最高(P<0.05);DEP组的RSES、MCSD及ISES得分均居中间水平;③仅条件自尊对OBC的检出有正向预测作用(B=0.193,P<0.05);条件自尊(B=0.189,P<0.05)及不稳定自尊(B=0.251,P<0.05)对DEP检出的预测效果显著;外显自尊(B=-0.242,P<0.05)、防御自尊(B=-0.106,P=0.088)及条件自尊(B=0.157,P<0.05)对AVD的检出预测效果显著。结论:①与正常大学生自尊结构相比,OBC大学生自尊属于条件化程度较高的高外显类型,而依赖型和回避型同属于高条件化的不稳定低自尊;②C类人格障碍组内比较,高条件化是共同特点,外显自尊和防御性以强迫型最高、回避型最低,不稳定性以强迫型最低、回避型最高,依赖型的自尊结构居二者之间;③自尊的条件化是C类各型人格障碍共同的危险因素,自尊的不稳定性对依赖型人格障碍有预测作用,而外显自尊水平及防御性仅对回避型人格障碍有负向预测作用。

Objective： To explore the heterogeneity of self-esteem among college students with symptom of Cluster-C personality disorders（PDs） and its prediction for picking out Cluster-C PDs.Methods： PDQC-2 was administered to a sample of 820 students to screen PDs and the feature of SE structure was examined by RSES,MCSD,CSES and ISES.Results： ①There were significant difference between OBC and normal students in CSES and ISES,and significant difference in all forms of SE between DEP/AVD and normal students.②There were no significant difference among Cluster-C PDs in CSES;OBC was the highest in RSES and MCSD and AVD was the lowest but the other way round on ISES;DEP was on the middle level in RSES,MCSD,ISES.③Only CSES could predict OBC;CSES and ISES had significant prediction of DEP;RSES,MCSD and CSES had significant prediction to AVD.Conclusion： ①Compared with normal students,OBC shows a high explicit and contingent self-esteem while there were contingent and unstable but low explicit self-esteem in both DEP and AVD.②High contingent self-esteem is common characteristic in Cluster-C PDs,and OBC has the highest explicit and defensive self-esteem,AVD the lowest,whereas instability in OBC and AVD reversed.And self-esteem structure of students with DEP the middle.③Contingence self-esteem is the risk factor to all Cluster-C PDs.Instability could predict DEP,but level of explicit self-esteem and defensive could only negatively predict AVD.
