目的:探讨品行障碍青少年中冲动性人格在焦虑与攻击之间的中介作用.方法:采用儿童多维焦虑问卷(MASC)、攻击量表(AQ)、Barratt冲动量表(BIS-11)对45名品行障碍青少年和63名健康青少年进行调查.结果:品行障碍患者中,焦虑、冲动人格和攻击性显著高于健康对照组.相关分析发现,在品行障碍组中焦虑、冲动性人格与攻击呈显著正相关;路径分析表明品行障碍组中冲动性人格在焦虑与攻击间起着完全中介作用,健康对照组中中介作用则不显著.结论:研究结果提示品行障碍患者的焦虑症状可能对攻击行为没有直接作用,而是通过冲动性人格的完全中介作用间接影响攻击行为.“,”Anxiety and conduct problems,having a high rate of comorbidity,affect a considerable proportion of children and may cause significant impairment in functioning.Recent studies have evidenced the implication of anxiety in the development of conduct disorder(CD),yet few studies have examined the psychological mechanism by which anxiety influences the psychopathology of conduct disorder.In this study,a series of self-report questionnaires were administered to 45 patients with CD and 63 healthy controls(HC) to evaluate aggression,impulsivity,and anxiety,respectively.ANCOVA including age as a covariate showed that anxiety,impulsivity and aggression were higher in CD patients compared to HC.Correlation analysis showed anxiety,impulsivity and aggression were correlated with each other positively and significantly in CD patients.Pathway analysis showed that the impulsivity fully mediated the effect of anxiety symptoms on the aggression in CD patients,but not in HC group.This study highlights the importance of the mediating effect of impulsiveness on the influence of anxiety symptoms on CD aggression.Our findings may be of valuable clinical implications that releasing impulse adaptively may be potentially helpful to relieve the influence of anxiety on the CD aggressive behaviors.
