This study examined the feasibility of a prize-based contingency-management (CM) approach to encourage interactive voice response (IVR) compliance in a cocaine-treatment study and explored the association between IVR call rate and outcome during a cocaine abstinence-induction trial. Subjects called into the IVR system daily to complete a brief interview assessing cocaine use for the past 24hours. One group earned $1 for each call; the other earned one draw per call from a "prize bowl" with a range of awards. Abstinence was rewarded according to a high-value voucher incentive schedule, which was the same for both groups, and confirmed by thrice-weekly urine testing at clinic visits. Odds of calling were 4.7 times greater (95% CI: 1.23, 17.91) in the prize-CM group than in the fixed dollar CM group. In addition, the percentage of IVR calls was significantly associated with abstinence achievement, χ(2) (1)=5.147, p<.023. The use of prize-based CM to increase the use of IVR is feasible and deserves examination as an innovation for helping participants engage in treatment.
本研究旨在探讨基于奖励的 contingency-management(CM)方法在可卡因治疗研究中鼓励交互式语音应答(IVR)依从性的可行性,并探讨在可卡因戒断诱导试验中 IVR 呼叫率与结果之间的关联。受试者每天通过 IVR 系统打电话,完成一项简短的访谈,评估过去 24 小时内的可卡因使用情况。一组每打一次电话可获得 1 美元;另一组则可从“奖池”中抽取一次,奖品范围很广。两组都根据高价值代金券奖励计划获得奖励,该计划在诊所就诊时通过每周三次的尿液检测进行确认。与固定美元 CM 组相比,奖品-CM 组的呼叫几率高 4.7 倍(95%CI:1.23,17.91)。此外,IVR 呼叫的百分比与戒烟的实现显著相关, χ(2)(1)=5.147,p<.023。使用基于奖励的 CM 来增加 IVR 的使用是可行的,值得作为帮助参与者参与治疗的创新手段进行研究。
