Abbreviations: CI, confidence interval; BMI, body mass index; NA, negative affect; PA, positive affect; EE, eating expectancy; AB, attention bias score; SE, standard error; between, grand-mean centered variable; within, person-mean centered variable; compensatory behavior, presence or absence of compensatory behaviors (reference category = compensatory behavior group). Within-person variables were lagged from the previous ecological momentary assessment signal. Negative affect model summary statistics: Akaike Information Criterion = 3,545.89; Bayesian Information

Criterion = 3,558.71; −2 log likelihood = 3,539.25. Positive affect model summary statistics: Akaike Information Criterion = 3,546.39; Bayesian Information

Criterion = 3,559.82; −2 log likelihood = 3,540.35. Exponentiated coefficients are similar to odds ratios.

a

Reflects the residual variance at each measurement.

b

Reflects the residual correlation between consecutive measurements.
