This study assessed the effectiveness of building partnerships with community resources and systems for court-referred clients and their families through a participant outcome evaluation. Specific variables studied included change in substance abuse patterns, family well-being, child safety, and recidivism. Results from pre-post testing revealed that a model with a single case coordinator who collaborated across service providers was particularly effective with court-referred clients and their families for increasing family intimacy and child well-being and for decreasing family danger and conflict. Discussion and recommendations are included.
