Eating pathology and DSM-III-R bulimia nervosa: a continuum of behavior

This longitudinal survey study of 557 college women used the new Eating Pathology Scale to classify respondents as nondieters, casual dieters, intensive dieters, dieters at risk, and bulimic. Shifts in the severity of dieting behavior over a 6-month period occurred primarily between adjacent scale categories. While new cases of bulimia were drawn from intensive dieters and dieters at risk, those women who no longer met DSM-III-R criteria for bulimia nervosa continued to engage in bulimic behavior.
