Five studies are reviewed which indicated the effectiveness on weight loss by mentally retarded persons of a treatment program stressing self control. The intervention included procedures which increased the dieter's self awareness of overeating behavior patterns and body weight, reduced food cues, reduced eating rates, increased activity level and reduced calorie intake. Ss were required to keep a record of the food they ate, their body weight, and a subjective appraisal of their adherence to the program. Studies included mildly and moderately retarded persons and substantiated the behavioral weight reduction approach. The dieters continued to lose weight during a planned maintenance phase, and in three of five studies, beyond that point. (CL)
