Abstract:
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.
