ABSTRACT
Objective To explore the mediation effect of adult attachment on the relationship between childhood trauma and borderline personality disorder(BPD) in recruits.Methods Childhood trauma questionnaire-28 short form (CTQ-SF),adult attachment scale (AAS) and personality diagnostic questionnaire-4+ (PDQ-4+) were administered to 1 750 recruits in the autumn of 2013.Results The scores of physical neglect,emotional neglect,emotional abuse,sexual abuse,physical abuse,attachment anxiety,attachment close and dependence and BPD were 11.05±3.04,10.00±3.54,6.73±2.32,5.92±2.06,5.83± 1.97,3.02 ± ±0.53,3.19±0.44,2.45± 2.04,respectively.BPD had significantly positive correlation with childhood trauma and attachment anxiety (r=0.353,0.284,P＜ 0.01),and significantly negative correlation with attachment close and dependence(r=-0.198,P＜0.01).Childhood trauma,attachment close and dependence and attachment anxiety could positively predict BPD(F=142.172,P＜0.01),which could explain 19.6％ of the total variation.Structure equation model and Bootstrap test showed that childhood trauma not only directly predict BPD in recruits,but also indirectly predict BPD in recruit through attachment close and dependence and attachment anxiety (x2/df=11.472,RMSEA =0.077,NFI =0.943,RFI =0.901,IFI =0.948,TLI =0.902,CFI =0.948),and the mediational path through attachment close and dependence and attachment anxiety with the effect size were 10.8％ and 8.1％,and the total mediational effect size was 18.9％.Conclusion Adult attachment exerts a multiple mediation effect on the relationship between childhood abuse and BPD in recruits.
ABSTRACT
Objective To explore the relationship between personality and depression,especially to investigate mediating effect of positive mental characters.Methods A sample of 1 933 male recruits was assessed with eysenck personality questionnaire (EPQ),positive mental characters scale for recruits (PMCS-R) and self-rating depression scale (SDS).Results The scores of introversion-extroversion,psychoticism,neuroticism,positive mental characters and depression were 55.26±10.59,42.85±7.25,42.35± 11.67,3.80±0.64,0.45±0.11,respectively.There were correlations among personality,positive mental characters and depression in recruits (P＜0.05).Regression analysis indicated that introversion-extroversion,psychoticism and neuroticism predicted depression directly,and it could explain 42.6％ of the total variance (F=476.28,P＜0.05).Hierarchy regression analysis showed that positive mental characters mediate the relationship between personality (introversion-extroversion,psychoticism,neuroticism) and depression (the mediation effect was 0.22,0.19 and 0.11 respectively,P＜ 0.05).Conclusion Recruits' personality affects depression not only directly,but also indirectly through positive mental characters.
