作者试图重复以前的研究结果，即体重抑制是治疗完成和治疗结果的重要预测因子（M。L. Butryn，M. R.洛，D. L. Safer，& W. S. Agras，2006）和治疗后体重增加（M. R. Lowe，W.戴维斯，D.卢克斯河A. Annunziato，& M. L. Butryn，2006年）。作者还检查了体重变异性的2种替代指标。参与者是132名接受认知行为疗法治疗的神经性贪食症女性。退出治疗的参与者的体重抑制水平并没有显著高于治疗完成者。在完成治疗的患者中，体重抑制并不能显著预测治疗后的暴饮暴食和腹泻。体重抑制确实显著预测了体重变化，特别是治疗期间的体重增加（>= 5 kg）。体重变异性的替代指标不能显著预测治疗完成或治疗结果，但我测量了治疗期间显著预测的体重增加。总之，作者未能复制先前的发现，即体重抑制预测治疗依从性和治疗结果，但他们确实复制了体重抑制预测治疗后体重增加的发现。
The authors attempted to replicate previous findings that weight suppression is a significant predictor of treatment completion and treatment outcome (M. L. Butryn, M. R. Lowe, D. L. Safer, & W. S. Agras, 2006) and weight gain over treatment (M. R. Lowe, W. Davis, D. Lucks, R. A. Annunziato, & M. L. Butryn, 2006) among women with bulimic disorders. The authors also examined 2 alternative measures of weight variability. Participants were 132 women with bulimia nervosa treated with cognitive-behavioral therapy. Participants who dropped out of treatment did not have significantly higher levels of weight suppression than did treatment completers. Among those who completed treatment, weight suppression did not significantly predict binge eating and purging at post-treatment. Weight suppression did significantly predict weight change and, in particular, weight gain (>= 5 kg) over treatment. Alternative measures of weight variability did not significantly predict treatment completion or treatment outcome, but I measure significantly predicted weight gain over treatment. In conclusion, the authors failed to replicate the previous finding that weight suppression predicts treatment compliance and treatment outcome, but they did replicate the finding that weight suppression predicts weight gain over treatment.
