情绪调节策略对海洛因戒断者跨期决策的影响

The influence of emotion regulational strategies on delayed discount of the abstinent heroin abusers

目的考察情绪调节策略在海洛因戒断者负性情绪和跨期决策之间的作用。方法实验采用2(被试类型:海洛因戒断组、对照组)×3(情绪调节策略:无、表达抑制、认知重评)两因素混合实验设计,使用延迟折扣任务对31名海洛因戒断者、33名对照组被试进行试验。结果在跨期决策任务的衡量指标曲线下面积(area under the curve, AUC)上,海洛因戒断者的AUC值显著低于对照组的AUC值;两组被试在认知重评策略下的AUC都显著高于无策略条件(P<0.05),表达抑制策略与其他两种策略均不显著(P>0.05)。结论海洛因戒断者的跨期决策能力低于对照组;认知重评策略可以降低负性情绪体验从而改善跨期决策的表现。未来可适当采用认知重评等情绪调节策略对海洛因戒断者的负性情绪进行干预,减少冲动决策和戒断后复吸。

Objective To investigate the effect of emotional regulation strategies on the relationship between negative emotions and inter-temporal decision-making in abstinent heroin abusers. Methods The experiment was conducted by using two factor mixed experiment design, 2(subject type: the abstinent heroin users/the control group)×3(emotion regulation strategy: no strategy/expression suppression/cognitive reappraisal).The delayed discount task was used to conduct experiments on 31 abstinent heroin users and 33 control group subjects. Results In the area under the curve(AUC), which is a measure of inter-temporal decision-making tasks, the AUC of abstinent heroin users was significantly lower than the control group;the two groups were in the cognitive reassessment strategy was significantly higher than the no strategy condition(P<0.05), and the expression suppression strategy was not significant with the other two strategies(P> 0.05). Conclusion The inter-temporal decision-making ability of abstinent heroin users is lower than that of the control group. Cognitive reappraisal strategy can reduce the individual′s negative emotion experience and reduce the negative impact of negative emotions on their inter-temporal decisions. In the future, cognitive reappraisal and other emotion regulation strategies can be used to regulate the negative emotions of the abstinent heroin users, so as to avoid impulsive decision-making and relapse after withdrawal.
