ABSTRACT

Objective:To explore the tri-relationship among the different types of early trauma,personality traits and obsessive-compulsive symptoms,and to analysis the mediating effects of maladaptive personality traits between early trauma and obsessive-compulsive symptoms.Methods:A total of 147 obsessive-compulsive patients were selected.The Yale-Brown obsessive-compulsive scale (Y-BOCS) was used to measure the degree of obsessive-compulsive symptoms,the Early Trauma Inventory Short Form (ETI-SF) was used to measure the early trauma experience,the NEO Five-Factor Inventory (NEO-FFI) was used to measure the personality characteristics.Results:The emotional abuse subscale scores of ETI-SF were positively correlated with the total scores of Y-BOCS (r =0.19;P ＜0.05),the neuroticism scores of NEO-FFI were positively correlated with the total scores of Y-BOCS (r =0.31,P ＜0.001),while the agreeableness scores of NEO-FFI were negatively correlated with the total scores of Y-BOCS (r =-0.18,P ＜0.05).The pathway analysis showed the indirect effects from emotional abuse to Y-BOCS via neuroticism were 0.107 (95％ CI0.04-0.19,P ＜ 0.05),the neuroticism play a completely mediated role.Conclusion:Early emotional abuse may be positively correlated with obsessive-compulsive symptoms,while the neuroticism may play a completely mediating role between the early emotional abuse and obsessive-compulsive symptoms.
