The role of avoidance and inflexibility in characterizing response to contingency management for cocaine use disorders: A secondary profile analysis.

Abstract

Contingency management (CM) is a reinforcement-based approach that provides tangible rewards for objectively verified drug abstinence. CM is the most effective available behavioral intervention for cocaine use disorders; however, response to CM is variable, with significant rates of nonresponse. In the present investigation, we conducted a secondary profile analysis to identify potentially modifiable cognitive-affective characteristics associated with CM response (abstinence vs. continued use) preceding a pharmacotherapy trial for cocaine dependence. Ninety-nine cocaine-dependent, treatment-seeking adults participated in a 4-week baseline CM procedure using high-value vouchers for submission of cocaine-negative urines. Separate profiles for responders and the nonresponders were established using standardized mean scores on relevant pretreatment measures of negative affect, experiential avoidance, cocaine withdrawal/craving, and impulsivity. Results indicated no differences between responder subgroups on baseline levels of negative affect, withdrawal/craving, or impulsivity; however, CM nonresponders, relative to responders, reported significantly higher levels of avoidance and behavioral inflexibility (p < .01) in the context of distressing cocaine-related thoughts, feelings, and bodily sensations. These data suggest that emotion regulation skills may serve as a therapeutic strategy for enhancing response to CM for cocaine use disorders. (PsycINFO Database Record
