Objective: We examined how attributions of broad ambiguous desire symptoms (eg, irritability) and elaborations on specific substances (ie, caffeine/food) influence subsequent self-reported cravings for these substances. Participants: 346 undergraduates were randomized to attribute their ambiguous desire symptoms to a lack of caffeine, food, or a vacation (active control), and then elaborate on the assigned stimulus. There was also a no-elaboration control group. Methods: Generalized Linear Models were used to test whether elaborating on one substance would increase cravings for that substance and decrease craving for the unelaborated substance relative to controls. Results: Participants who elaborated in terms of food reported increased food cravings, whereas participants who elaborated in terms of caffeine reported increased caffeine cravings. Conclusions: Findings suggest that food and caffeine cravings are malleable, and point to the importance of elaboration in polysubstance contexts. Food and caffeine elaborations may matter for heightening craving and determining the targets of craving.
