Compared to controls, ISP probationers had significantly more prior involvement with the criminal justice system and more special problems. While they received more services overall, and significantly more in the area of mental health and welfare, they also received significantly less individual and family counseling than did controls. While ISP subjects received more contacts, the number of face-to-face contacts was below program goals. Overall, the high-risk group had 20.3 percent incarcerated as compared to 13.4 percent for the control group; but this difference was not significant. However, offenses of the high-risk group were no more serious than those of controls. Finally, ISP subjects were found to be making a less positive social adjustment than were controls. Results suggest that, although the program did not operate as an ideal of intensive supervision, it is possible to divert high-risk/need offenders from prison without seriously jeopardizing community safety. 15 references.
