目的:探讨甲卡西酮成瘾者和冰毒成瘾者的决策特点。方法:从某强制隔离戒毒所筛选出甲卡西酮成瘾者45人,冰毒成瘾者41人,从某大学后勤工作人员中招募对照组被试33人,分别使用冲动性量表(BIS-11)、杯子任务研究被试的冲动性水平和决策特点。结果:冰毒成瘾组的冲动性显著高于对照组和甲卡西酮成瘾组;在收益情境下,甲卡西酮成瘾组和冰毒成瘾组选择风险选项的比例显著高于对照组,甲卡西酮成瘾组和对照组比冰毒成瘾组选择更多的适应性选项;在损失情境下,三组被试选择风险选项和适应性选项的比例不存在显著差异。结论:在收益情境下,成瘾组比对照表现出更明显的风险决策偏好,只有冰毒成瘾组表现出非适应性决策。
Objective: To explore the decision-making characteristics of methadone addicts and methamphetamine addicts. Methods: Forty-five methamphetamine addicts and 41 methamphetamine addicts were screened from a forced isolation detoxification center and 33 control subjects were enrolled from a university back-office staff. The impulsiveness scale (BIS -11), cup task to study the impulse level and decision-making characteristics of the subjects. Results: The impulsivity of methamphetamine addicts was significantly higher than that of the control and methaconeone addicts. In the return scenario, the proportion of risk factors for methadone addiction and methamphetamine addiction was significantly higher than that of the control , Methadone addiction group and control group had more adaptability options than those of methamphetamine addiction group. There was no significant difference between the three groups in the proportion of risk option and adaptive option in the case of loss.
