Significant needs exist for increased and better substance abuse treatment services in our nation's prisons. The TCU Organizational Readiness for Change (ORC) survey has been widely used in community-based treatment programs and evidence is accumulating for relationships between readiness for change and implementation of new clinical practices. Results of organizational surveys of correctional counselors from 12 programs in two states are compared with samples of community-based counselors. Correctional counselors perceived strong needs for new evidence-based practices but, compared to community counselors, reported fewer resources and less favorable organizational climates. These results have important implications for successfully implementing new practices.
