An attempt was made to analyze systematically the effect of mandatory treatment of offenders scoring at each supervision classification level (minimum, medium, and maximum) for four base expectancy scale methods.
Abstract
The models examined were the California BE61A, the Revised Oregon Model, the United States Parole Commissions's Salient Factor Score, and the U.S.D.C. 75 Scale. Subjects included 89 offenders for whom mandatory treatment was a special condition of probation and 91 offenders who were not required to undergo treatment. For those in the minimum supervision category, data indicate that the California BE61A and the U.S.D.C. 75 Scale presented a greater failure percentage for the nontreatment group. The Salient Factor Scale reflected a greater failure percentage for the nontreatment group, and the Revised Oregon Scale relfected zero failure in both groups. Treatment probationers scoring in the medium category failed less on each base expectancy scale, suggesting that treatment had a positive effect on them. In the maximum category, findings were similar, with treatment group members failing less on each scale than the nontreatment group. Overall, results support the continued use of court-ordered treatment in the probation system. However, the methods of determining who is treated is an area which requires further study. Tabular data and 14 references are provided.
