This study evaluated the effectiveness of nondieting versus dieting treatments for overweight, bingeeating women. Participants (N = 219) were randomly assigned to 1 of 3 groups: diet treatment (DT), nondiet treatment (NDT), or wait-list control (WLC). DT received a balanced-deficit diet reinforced with behavioral strategies. NDT received therapy designed to help participants break out of their dieting cycles. Treatment in both conditions was administered in weekly groups for 6 months, followed by 26 biweekly maintenance meetings, for a total of 18 months of contact. At 6 months posttreatment, DT lost 0.6 kg while NDT gained 1.3 kg. Both treatment groups reduced their Binge Eating Scale scores significantly more than WLC. At 18-month follow-up, both treatment groups experienced weight gain but maintained similar reductions in binge eating. Results indicate that neither intervention was successful in producing short-or long-term weight loss. Therapist biases, which may have affected treatment integrity, and other methodological issues are discussed in relation to the small weight losses achieved. Estimates of binge eating among obese patients range from 20% to 50%, depending on the criteria used and the study population (Bruce & Wilfiey, 1996; It is unclear whether or not binge-eating obese patients experience greater difficulty in treatment programs as a result of these liabilities. Obese binge eaters have been found to respond to weight loss programs similarly to nonbingers, and experience similar or lower attrition rates This research was supported by National Institute of Diabetes and Digestive and Kidney Diseases Grant DK43109 and by a Minority Scientist Development Award from the American Heart Association and its Puerto Rican Affiliate.

Method Participants The mean age of participants was 40 years (SD = 6.3, range = 25 to 50 years). Participants' mean pretreatment weight was 88 kg (SD = 9.6, range = 66 to 110 kg). The mean body mass index (BMI) was 33 kg/m 2 (SD = 3.4), with a range of 26 to 43 kg/m 2. The ethnic-racial composition of the sample was 85% White, 8% Black, and 7% Hispanic. Of the total participants, 62% were married, 21% were single or divorced, and 17% were never married. Twenty-four percent of the participants had a college degree, 65% had some college, and 11% had a high school diploma or less. Sixty-nine percent were employed full time, and 9% part time. Procedure Female participants were recruited from Houston and the surrounding area using print and electronic media to publicize the study. Those 36
