Objective To examine changes in dietary restraint patterns revealed by the Eating Disorders Examination Restraint subscale (EDE‐R) and the Three‐Factor Eating Questionnaire Cognitive Restraint scale (TFEQ‐CR) in a large sample of women with bulimia nervosa (BN) who completed 18 weeks of cognitive‐behavioral therapy (CBT). Method Data from 134 subjects were obtained from a larger study and analyzed using repeated‐measures analysis of variance (ANOVA). Results The EDE‐R showed statistically and clinically significant decreases post‐CBT, whereas the TFEQ‐CR did not change significantly. Discussion This is the first study to directly compare the EDE‐R and TFEQ‐CR before and after CBT in the same population. The contrasting results suggest the two measures tap different aspects of the dietary restraint construct. The EDE‐R may primarily reflect dieting to lose weight whereas the TFEQ‐CR may reflect dieting to avoid weight gain. In assessing changes in dietary restraint targeted by CBT for BN, the TFEQ‐CR appears less useful. © 2004 by Wiley Periodicals, Inc. Int J Eat Disord 36: 83–88, 2004.
