Substance abuse treatment programs in the South Central VISN were matched on program characteristics and current depression management practices (n = 4), and "intervention" sites were randomly chosen from each pair. Phase 1 (now completed) of the study analyzed the barriers and facilitators to translation of depression management in participating facilities, and used these data to inform the development of the translation intervention, its implementation tools, and the depression algorithm. The translation intervention adopted in this plan was based on the PRECEDE model of organizational behavior change and included provider education, use of local champions, feedback of screening data, and patient education/activation. The depression management algorithm and intervention was developed with input from programs staff and an Advisory Panel of depression management and translation experts. Phase 2 of the study implemented and tested the intervention. The evaluation in examining program- and provider-level outcomes. Program-level outcomes include feasibility, extent of adoption of the algorithm, and provider/organizational attitudes and beliefs about the intervention's design and effectiveness. Patient-level outcomes include depressive symptoms, substance use outcomes, medication adherence, quality of life, and services use.
