A variety of survey techniques were used in the research. Data were collected in two stages. The first stage focused on the person at the system level most directly responsible for the planning, implementation, or oversight of SI programming. The second stage targeted the site-level administrator and substance abuse treatment/education provider. The purpose of this two-stage data collection was to ascertain the amount of congruence in the perceptions held by individuals responsible for the programming at differing levels of correctional systems. The survey results suggest that SI facilities are anchored in an adherence to rehabilitative ideology and that a strong emphasis has been placed on promoting offender change. This trend reflects the emergence of "second generation" SI programs that are moving away from a basic military model and toward a more therapeutically oriented regimen. An examination of drug treatment programming in SI facilities suggests that despite an increasing emphasis on drug treatment programming, there is still confusion as to what constitutes such programming in SI facilities. 6 tables and 1 figure
