Objective:To explore the relationship between depressive symptoms and childhood abuse and neg-lect in college students,and the roles of attentional control and attentional bias in their relationship.Methods:Total-ly 871 students from a medical university in Guangzhou were recruited to complete the Patient Health Question-naire-9(PHQ-9),Childhood Trauma Questionnaire(CTQ),Attention Control Scale(ACS),and Attention to Posi-tive and Negative Information Scale(APNI).The summed scores of emotional abuse,physical abuse and sex abuse subscale of CTQ were computed to measure childhood abuse,while the summed scores of emotional neglect and physical neglect subscale of CTQ were computed to measure childhood neglect.Results:Childhood abuse and child-hood neglect scores were both positively associated with PHQ-9 scores(β=0.01,0.01),and negatively associated with ACS scores(β=-0.30,-0.14).Childhood abuse scores were positively associated with negative attentional bias scores(β=0.24),and negatively associated with positive attentional bias scores(β=-0.14).Childhood neg-lect scores were negatively associated with positive attentional bias scores(β=-0.22).Attentional control and at-tentional bias played mediating roles between childhood abuse,childhood neglect and depressive symptoms,and the mediating effects accounted for 53.99％and 40.28％of the total effects,respectively.Conclusion:Depressive symptoms in college students are related to both childhood abuse and neglect,and attentional control and positive,negative attentional bias mediate such associations.
