The present study investigated the effect of two craving reduction techniques, namely, cognitive defusion and guided imagery, on naturalistic food cravings. These techniques targeted the intrusion and elaboration stages of the craving process, respectively (Kavanagh, Andrade, & May, 2005). Participants underwent a seven-day baseline period followed by a seven-day intervention period, during which they recorded their food cravings as they occurred using online diaries accessed via smartphone. In the intervention period, participants were randomly assigned to one of cognitive defusion, guided imagery or control conditions. Participants in the cognitive defusion and guided imagery conditions listened to three-minute audio clips containing their respective instructions every time they experienced a food craving, and rated their craving intensity before and after the intervention, while the control participants recorded their cravings as they did in the baseline week. Results showed that both cognitive defusion and guided imagery techniques reduced craving frequency, intensity, the likelihood of consumption following cravings, and craving-related calorie intake, consistent with predictions. These findings show that cognitive defusion and guided imagery are useful for dealing with naturally occurring cravings across a range of foods, and can reduce craving-related consumption in everyday life.
本研究调查了两种减少渴望的技术,即认知解离和引导想象,对自然发生的食物渴望的影响。这些技术分别针对渴望过程的侵入和阐述阶段(Kavanagh、Andrade 和 May,2005)。参与者经历了为期七天的基线期,然后是为期七天的干预期,在此期间,他们使用智能手机访问的在线日记记录了他们发生的食物渴望。在干预期间,参与者被随机分配到认知解离、引导想象或对照组。认知解离和引导想象组的参与者每次经历食物渴望时都会听三分钟包含各自指令的音频片段,并在干预前后评估他们的渴望强度,而对照组的参与者则按照基线周的方式记录他们的渴望。结果表明,认知解离和引导想象技术都降低了渴望的频率、强度、渴望后消费的可能性以及与渴望相关的卡路里摄入量,这与预测一致。这些发现表明,认知解离和引导想象对于处理各种食物中的自然发生的渴望是有用的,并可以减少日常生活中的与渴望相关的消费。
