Shame facets as predictors of problematic eating behaviors: An ecological momentary assessment study

Abstract

It is well-established that negative affect acts as predictor and maintenance factor of problematic eating behaviors. However, the relevance of different facets of negative affect is unclear. While guilt was consistently shown as having a relevant contribution in relation with problematic eating patterns, shame might play a similar role. The current study used an ecological momentary assessment design to assess associations between facets of shame and subsequent disturbed eating behaviors. The study included 57 females with high levels of eating disorders (ED) symptomatology who completed five surveys per day for 14 consecutive days. Participants completed measures of facets of shame (i.e., general shame, body shame, shame around eating), negative affect and problematic eating behaviors (i.e., binge eating, restriction, weighting, body checking, purging, taking laxative/diuretics and excessive exercise). Data were analyzed using multilevel models. In general, between-subjects facets of shame were associated with more disturbed eating behaviors, with shame explaining a significantly and clinically relevant percent of the variance of these problematic eating behaviors. At the within-subject level, facets of shame predicted subsequent binge eating, body checking and excessive exercise. These findings support the role of shame in ED symptomatology and the relevance of directly tackling shame in psychological treatments.
