生物反馈结合线索暴露治疗降低海洛因依赖者药物线索反应

目的:了解生物反馈结合线索暴露治疗是否降低海洛因依赖者环境线索诱发渴求及心理生理反应.方法:采用前瞻性的队列研究将60例环境线索诱发心理渴求增高的康复期海洛因依赖者分成实验组(n=36)与对照组(n=24),对照组只进行劳教场所的常规帮教,实验组除帮教外进行12次生物反馈结合线索暴露治疗,评估治疗前后环境线索诱发心理渴求与心理生理反应情况.结果:两组治疗结束后,实验组环境诱发前、后的心理渴求,肌电和皮导得分均低于对照组[诱发前:心理渴求(3.06±7.26)mm vs.(22.32±20.26)mm、肌电(8.52±4.23)μV vs.(12.06±5.17)μV、皮导(2.14±1.43)μS vs.(4.61±2.24)μS;诱发后:心理渴求(6.97±10.30)vs.(33.14±25.40)mm、肌电(8.72±4.31)vs.(14.79±5.86)μV、皮导(2.15±1.33)vs.(4.49±2.59)μS,P≤0.01].结论:生物反馈结合线索暴露治疗可降低康复期海洛因依赖者渴求及环境诱发心理生理反应.

Combination of Biofeedback Therapy and Cue-exposure Therapy Decreased Heroin-related Cue Reactivity in Abstinent Heroin Dependents

Objective:To understand whether or not biofeedback therapy(BT)and cue- exposure therapy(CET)could decrease craving and heroin-related cue reactivity in abstinent heroin dependents.Methods:Adopting stratified sampling means,60 abstinent heroin dependents whose craving increased after cue exposed,were allocated to experiment group(n=36)and control group(n=24).The control group dependents received assistance and education.Beside the assistance and education,the experiment group also received 12 times combination therapies of BT and CET.Results:After therapies,the experiment group dependents' craving,EMG and skin conductance(SC)were all decreased compared with control group before cue exposures and after cue exposures[Before cue exposures,the indexes were:craving(3.06±7.26)mm vs.(22.32±20.26)mm;EMG(8.52±4.23)μV vs.(12.06±5.17)μV,SC(2.14±1.43)μS vs.(4.61±2.24)μS.After cue exposures the indexes were:craving(6.97±10.30)mm vs.(33.14±25.40)mm,MEG(8.72±4.31)μV vs.(14.79±5.86)μV,SC(2.15±1.33)μS vs.(4.49±2.59)μS;Ps≤0.01.Conclusion:The combination of biofeedback therapy and cue-exposure therapy could decrease the dependents' craving and cue reactivity sensitivity.
