Abstract

Data collected over the last decade has begun to implicate behavioural impulsivity in overeating behaviour. How- ever, recent work has suggested that the reinforcing value of food may be associated with impulsive choice (a sub-type of impulsivity), but to date no study has examined how the reinforcing value of food relates to other as- pects of impulsivity. To examine these inter-relationships, 80 women completed measures of eating (a snack in- take test and the Three-Factor Eating Questionnaire and then in a separate test session an inhibitory control task, a delay discounting task, a reflection impulsivity task, and a measure of the reinforcing value of their chosen snack foods. Participants also completed the Behavioural Inhibition System/Behavioural Activation System (BIS/BAS) questionnaire to examine self-report and behavioural parallels between measures. In regression models, only Be- havioural Inhibition System subscales of the BIS/BAS predicted increased responding on the reinforcing value of food task. The reinforcing value of food task predicted and trended to predict calorie and grams intake of snack foods in regression models, supporting RRV as a predictive measure of short-term snack intake. Likewise, impul- sive choice and inhibitory control was not related to eating measures. Methodological implications are discussed.
