Seventeen trainable mentally retarded youths were assigned to either a behavior therapy (N = 6), an obese wait·list control group (N = 5) or a normal weight control group (N = 6). The behavior therapy subjects lost significantly more weight than the two control groups who gained weight. The behavior therapy subjects achieved significant reductions in tricep skin· fold thickness, abdominal circumferences, and diastolic blood pressure measures by the end of the 21·week treatment program. The advantages of using multiple dependent measures is discussed.
