Testing cognitive defusion and guided imagery as food craving reduction techniques in the field

Abstract

Background: Elaborated-Intrusion theory gives rise to two craving reduction techniques (cognitive defusion and guided imagery) that target specific stages of the food craving process. Extending upon previous research that supported their use in laboratory settings, the present study aims to test these techniques against a no-task control in the field. Methods: Participants (aim n = 75, women aged 17-25) will keep an online food diary for 2 weeks (baseline). They will record information about their cravings (e.g., foods craved, triggers, intensity) and consumption, including meals and snacks. Participants will then be randomly allocated to three conditions (cognitive defusion, guided imagery or control). During the following 2-week period (intervention), participants in active conditions will use their respective technique every time they experience a food craving, and continue recording craving-related information in their online diaries. Expected results: The effect of these techniques on food cravings and subsequent consumption will be analysed using a 3 (condition: cognitive defusion, guided imagery, control) x 2 (time: baseline, intervention) mixed-factorial ANOVA. It is predicted that the two techniques will reduce cravings and consumption relative to the no-task control. Current stage of work: The first wave of data collection is scheduled to begin in March. Discussion: To our knowledge, the present study is the first to compare cognitive defusion and guided imagery as craving reduction techniques in a field context, providing a more ecologically valid research setting. Findings will offer insight into real-world applicability of these techniques to reduce the experience of food craving, and craving-related consumption.
