The behavior modification movement has its full quota of prophets, critics and Don Quixotes. In general, the literature has been deficient in reports which present "hard" data, describing successful treatment of children who have multiple sets of problem behavior. All three deficiencies will have to be met before behavior modification technology can occupy a respectable position. The behavioral items and symptom list had been previously used with a sample of one hundred deviant boys to determine the factor structure which characterized this matrix. A paradigm such as the one currently being used by behavior modifiers may generate statements which lead to successful outcomes of treatment programs. The data showed that by the second day of conditioning there was a dramatic drop in the occurrence for both classes of deviant behavior. In both cases, the rate of occurrence dropped to almost zero and stayed there during the remainder of the three-month follow-up period.
