Although weight variability has been predictive of eating\u2010 and weight\u2010related variables in community samples, it has not been empirically examined in eating disorders. The current study examined cross\u2010sectional and prospective associations between weight variability and BN pathology.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Four weights were collected over an average of 42.02\u2009days, and weight variability was calculated as the root mean square error around each individual's weight trajectory regression line. Linear regressions were performed to examine the association between weight variability and eating disorder psychopathology, cross\u2010sectionally at baseline and prospectively at 6\u2010month follow\u2010up, adjusting for baseline BMI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Weight variability was cross\u2010sectionally associated with eating pathology, but these relationships became non\u2010significant after adjusting for BMI. However, at 6\u2010month follow\u2010up, greater baseline weight variability predicted increases in body dissatisfaction, shape and weight concerns, and global eating pathology, even after adjusting for baseline BMI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>These findings demonstrate, for the first time, that within\u2010subject weight variability predicts greater eating disorder pathology over time in BN.
