Many people under community supervision and addicted to opioids or alcohol could benefit from substance abuse treatment that includes medication-assisted treatments. However, conflicting attitudes toward MATs and competing organizational priorities in many jurisdictions complicate the inter-organizational strategy used to arrange this treatment. The authors study the effectiveness of an Organizational Linkage Intervention to bridge existing treatment gaps and mediate conflicts between community corrections and treatment agencies. The results of their study show accomplishments in improving communication between probation and treatment agencies and potential barriers that may persist.
