The effect of mood induction on the amount eaten by bulimics and nonbulimics
Abstract
This study investigated the differential effects of experimental mood induction on the eating behavior of bulimics and nonbulimics. Following the induction of a negative, neutral, or positive mood state, subjects taste-tested three flavors of ice cream. The number of kilocalories of ice ream consumed was found to vary as a function of mood condition and bulimic or nonbulimic group categorization. Bulimics ate more in the negative and neutral than in the positive mood treatment; whereas, nonbulimics ingested more in the positive than in the negative or neutral condition. Furthermore, bulimics ate more than nonbulimics in the negative and neutral mood treatments. Because both the negative and neutral mood conditions were found to be aversive, these results provided support for a negative affect model for the bulimic syndrome, which postulates that negative emotional states precipitate binge-eating. Further implications for theory, treatment, and research are discussed.
