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.

Twenty obese and twenty normal‐weight children participated in the present study which examined the applicability of Singh's deficit in response inhibition theory to preadolescents. The first experiment served as a test of the theory on a food‐related task and as a replication of one of Singh's studies with adults. The results failed to support Singh's findings. The second experiment tested the theory using a nonfood‐related reaction time task and again the results were negative. This suggests that Singh's theory and findings do not apply to children ages 8–12. Since Milich and Fisher (1979) also failed to support Singh's theory using a heterogeneous nonstudent population of obese adults, a revaluation appears necessary.
