In this broad grouping of programs, intensive supervision probation/parole (ISP) emphasizes a higher degree of surveillance than traditional supervision in the community. The average number of face-to-face monthly contacts for studies included in our metaanalysis was 12. ISP could be delivered in lieu of incarceration, as a conditional release from incarceration in the form of parole, or as a probation sentence. Conditions of supervision vary across the studies, but some characteristics include urinalysis testing, increased face-to-face or collateral contacts, or required participation in treatment.
