Note. Correlations based on available data at each wave. Total sample n = 1906. Pub = Puberty; B = Binge eating; P = Purging; NU = Negative Urgency; NA = Negative Affect; EE = Eating Expectancies; and TE = Thinness Expectancies; each number following the variable represents the wave in which the data was collected. (i.e., NU-1 = Negative Urgency, Wave 1). Correlations with puberty, binge eating (Waves 2 and 3) and purging (Waves 2 and 3) are point-biserial correlations.
