Cue-induced craving is not easily reduced by an extinction or exposure procedure and may constitute an important route toward relapse in addictive behavior after treatment. In the present study, we investigated the effectiveness of counterconditioning as an alternative procedure to reduce cue-induced craving, in a nonclinical population. We found that a cue, initially paired with chocolate consumption, did not cease to elicit craving for chocolate after extinction (repeated presentation of the cue without chocolate consumption), but did so after counterconditioning (repeated pairing of the cue with consumption of a highly disliked liquid, Polysorbate 20). This effect persisted after 1 week. Counterconditioning moreover was more effective than extinction in disrupting reported expectancy to get to eat chocolate, and also appeared to be more effective in reducing actual cue-elicited chocolate consumption. These results suggest that counterconditioning may be more promising than cue exposure for the prevention of relapse in addictive behavior.
线索诱发的渴望不易通过消退或暴露程序减少,并且可能构成治疗后成瘾行为复发的重要途径。在本研究中,我们调查了条件反射作为一种替代程序来减少线索诱发的渴望的有效性,在非临床人群中。我们发现,最初与巧克力消费相关的线索在消退后(反复呈现线索而不消费巧克力)并没有停止引起对巧克力的渴望,但在条件反射后(反复将线索与消费一种非常不喜欢的液体聚山梨酯 20 配对)则会引起巧克力的渴望。这种效果在 1 周后仍然存在。条件反射在破坏报告的期望得到巧克力方面比消退更有效,并且似乎在减少实际线索引起的巧克力消费方面也更有效。这些结果表明,条件反射可能比线索暴露更有希望预防成瘾行为的复发。
