Main Methods:

• A cluster randomized clinical trial involving 138 patients across 16 mental health clinics.
• Outcomes measured at baseline, 6, and 12 months included symptom duration/severity and adherence.
• Collaborative care involved nurses as care managers, utilizing psychoeducation, problem-solving, and monitoring.

Main Results:
