Smith KE, Mason TB, Juarascio A, et al. - In this study, researchers examined a model that postulated momentary fluctuations in affect, eating expectancies, and attention bias (AB) would interact to predict subsequent binge eating. Completion of a 10-day ecological momentary assessment protocol with ambulatory measures of AB (ie, dot-probe task with palatable food and neutral cues) and self-report assessments of positive and negative affect, eating expectancies (ie, the belief that eating would improve one's mood), and binge-eating symptoms by 40 women with recurrent binge eating was reported. As per generalized linear mixed models, there is an association of higher momentary AB toward palatable food with increased risk of subsequent binge eating, and as per a two-way interaction, there was an association of moments of higher eating expectancies and negative affect with a heightened likelihood of subsequent binge eating. Together, the findings partly backed hypotheses and illustrate meaningful within-person fluctuations in AB that precede binge eating. Further, outcomes confirm that both affective state and attentional processes affect the momentary influence of eating expectancies on binge eating depends.
