焦虑在冲动性特质与进食障碍症状关系中的中介作用
Anxiety as mediator between impulsive traits and symptoms of eating disorders
摘要
Abstract
Objective:To explore the relationship between impulsivity traits,anxiety,and symptoms of eating disorders,with a focus on the mediating effect of anxiety between impulsivity and eating disorder symptoms.Me-thods:A total of 244 patients with eating disorders meeting the DSM-5 diagnostic criteria for anorexia nervosa(AN)and bulimia nervosa(BN)were enrolled,and the Eating Disorder Inventory-1(EDI-1),Barratt Impulsive-ness Scale(BIS-11),and the State Anxiety Inventory(SAI)were assessed.Mediation role analysis was performed by SPSS macro PROCESS program.Results:There was a significant positive correlation between the total score of BIS-11,SAI and EDI-1 in AN and BN patients(AN,r=0.56,0.63,0.72;P＜0.001.BN,r=0.51,0.31,0.56;P＜0.001 or P＜0.01).The total score of SAI played a mediating effect between the total score of BIS-11 and the total score of EDI-1,but the total score of SAI played a partial mediating effect(effect ratio was 46.9％)in patients with AN,and the total score of SAI played a full mediating effect in patients with BN.Conclusion:Impulsive trait and anxiety may be positive predictors of eating disorder symptoms.Anxiety mediates the relationship between impul-sivity trait and eating disorder symptoms,with a partial mediating effect in patients with AN and a full mediating effect in patients with BN.关键词
