摘　　要：目的探讨冰毒依赖者的行为决策特点。方法采用爱荷华赌博任务(IGT)对47例男性冰毒吸食者的决策行为进行评估,并根据性别、年龄(3)匹配的原则在当地社区、医院选取27例做正常对照。结果组间主效应(0.000,0.985)、区组内主效应(1.921,0.123)、交互效应(1.713,0.162)不显著,但正常对照组有回避不利选项的倾向,单独统计结果区组效应边缘显著,而吸毒者则无。结论冰毒吸食者的决策能力相对保存完好。Objective To examine the reward-related decision -making among methamphetamine dependent patients and healthy controls using the Iowa Gambling Task .Methods Contrast between 42 patients with methamphetamine dependence and 27 normal con-trols with the Iowa Gambling Task （ IGT） .Results The IGT results showed that there was no a significant interaction between group sta -tus and sessions on the IGT summary score（ 1.713,0.162）,there was not a significant main effect of group status （ 0.000,0.985）,and session（ 1.921,0.123）,but MD were significantly more likely to perform disadvantageously on trial 5 of the IGT.Conclusion The methamphetamine dependent patients dont demonstrate differences in reward -related decision -making relative to healthy controls .
