The present study sought to identify predictors of weight loss at the end of a 10‐week treatment program and during a 1‐year follow‐up period. Participants were 83 obese women solicited from the community by advertisement. Results showed that weight loss during the first week of dieting, a greater number of past weight loss attempts, and a larger monthly weight loss goal were predictive of outcome at the end of the 10‐week treatmetn program. Work status, age of onset of obesity, and the ratio of overcome urges to total urges to overeat were predictive of weight loss from the end of treatment to the 1‐year follow‐up. No pretreatment variables predicted follow‐up weight status. Frequency of bingeing, frequency of urges, and demographic variables (other than age of onset and work status) were not predictive of weight loss at any time. The lack of commonality between identified predictors of treatment and follow‐up outcomes supports the contention that the operative factors leading to weight control differ during the treatment and maintenance phases.
