The present study extended previous work with the multiple-choice procedure (MCP) by examining the monetary value of cocaine and alcohol in dual-dependent patients. Participants made hypothetical choices between pairs of substances and between each substance and a series of monetary values. Results showed that the combination of cocaine and alcohol was preferred over each individual substance. The monetary value at which the substance is no longer chosen was higher for the combination than for one drink or one hit alone. Monetary values showed convergence with dependence-related variables. These findings substantiate the importance of concurrent alcohol and cocaine dependence treatment.
本研究通过考察双重依赖患者中可卡因和酒精的货币价值，扩展了先前使用多项选择程序（MCP）的研究工作。参与者在成对的物质之间以及每种物质与一系列货币价值之间做出假设选择。结果表明，可卡因和酒精的组合比每种单独的物质更受青睐。该组合不再被选择时的货币价值高于单独一种饮料或一剂可卡因的货币价值。货币价值与依赖相关变量呈现出趋同性。这些发现证实了同时治疗酒精和可卡因依赖的重要性。
