目的:分析海洛因依赖者与正常人群的人格特征的不同特点,探讨人格特征与首次吸毒年龄的关系。方法:采用气质性格问卷(Temperament and character inventory,TCI)分别对100例海洛因依赖者与88例正常对照者进行人格评定。结果:①与正常对...目的:分析海洛因依赖者与正常人群的人格特征的不同特点,探讨人格特征与首次吸毒年龄的关系。方法:采用气质性格问卷(Temperament and character inventory,TCI)分别对100例海洛因依赖者与88例正常对照者进行人格评定。结果:①与正常对照组相比,海洛因依赖组的探求新奇性和伤害回避性得分高于对照组(P<0.05),而海洛因依赖组合作性、自我定向维度得分均数低于对照组(P<0.01)。②海洛因依赖者的TCI问卷不同维度的得分与首吸年龄无相关性,P>0.05。结论:①寻求刺激、冲动、探索、看事情悲观、害怕不确定、易疲劳等是海洛因依赖的易感人格特征。②首次吸毒年龄与TCI的不同人格维度之间无相关性。展开更多
