A self-administered questionnaire was mailed to probation agencies and departments in a random sample of 200 jurisdictions and a purposive sample of 21 jurisdictions representing the largest metropolitan areas and jurisdictions known to already have JIPS. The questionnaire asked for information on purpose and objectives, a program description, staffing, client profiles, classification and assignment criteria, and jurisdictional characteristics. Responses were received from 61 agencies with a JIPS component and 96 without one. JIPS programs were identified in 29 States representing all major regions of the country. States with the largest number of JIPS included California, Pennsylvania, Michigan, Minnesota, Ohio, Texas, and Wisconsin. Populations of jurisdictions with JIPS varied from over 5 million to only 13,000. The majority of programs operated under the auspices of the juvenile court. Of programs, 38 were structured as a separate entity, while 22 were integrated into standard probation operations. A majority of respondents placed primary emphasis on surveillance, although 11 showed greater reliance on treatment. A total of 92 percent of programs referred clients to outside agencies to obtain needed services and resources, and 78 percent stated that the program was used as a true alternative to incarceration. 1 footnote.
