Binge-eating episodes have alternately been described as stemming from strict dieting behaviors driven by overvalued ideas of weight and shape, or as arising from problematic interpersonal experiences. A third way of conceptualizing an eating binge is as a maladaptive emotion-regulation strategy, suggesting that facilitating more adaptive and effective affect regulation capacities may be a useful treatment. Dialectical Behavior Therapy (DBT), a treatment aimed at increasing emotion regulation skill, is currently being adapted for use with a binge-eating disorder population. Assumptions underlying the treatment, methods in treatment delivery, and goals of the treatment package are discussed. A pilot study currently underway of group DBT therapy for individuals with Binge-Eating Disorder is described. © 1999 John Wiley & Sons, Inc. J Clin Psychol 55: 755–768, 1999.
