Regression coefficients are standardized and all variables were centered using their grand mean prior to analysis. Sex: dummy-coded male = 1/female = 0; Ethnicity1: dummy-coded Blacks = 1/Whites = 0; Ethnicity2: Others = 1/Whites = 0.

^aMean scores for ESM-reported motives computed from group means for each participant. Analyses controlled for number of eating episodes and the interaction between the number of eating episodes and ESM-reported mean scores.

^∗Significant predictors, p < 0.05 and bolded.
