The introduction of behavior modification in the treatment of obesity a decade ago resulted in a substantial increase in weight loss of persons treated for mild to moderate obesity. It has been hoped that this increased effectiveness of treatment would extend also to maintenance of weight loss, and the first controlled clinical trial suggested that it did. This article reports the results of (1) a five-year follow-up of this first trial and (2) all follow-up studies of behavior modification for obesity yet conducted, six published and four previously unpublished. A new method of data analysis shows that weight losses are only modestly maintained, although the question of how their maintenance compares with that of other treatments cannot be answered because comparable data on other treatments are not available. In contrast to the vast amount of work on the initiation and generalization of behavior change, study of its maintenance has been a neglected area of behavior modification. We suggest that this area constitutes a new frontier for research in behavior modification.
十年前引入的行为矫正疗法用于治疗肥胖症，使得轻度至中度肥胖症患者的体重降幅显著增加。人们曾希望这种提高了的治疗效果也能延伸至体重减轻后的维持阶段，而首个对照临床试验表明确实如此。本文报告了（1）对该首个试验的五年随访结果，以及（2）迄今所有已开展的肥胖症行为矫正随访研究，其中六项已发表，四项此前未发表。一种新的数据分析方法显示，体重减轻的维持程度仅为适度，不过由于没有其他治疗方法的可比数据，所以无法回答其维持情况与其他治疗方法相比如何这一问题。与行为改变的启动和推广方面的大量研究工作形成对比的是，对行为维持的研究一直是行为矫正中一个被忽视的领域。我们认为这一领域构成了行为矫正研究的一个新前沿。
