RESUMEN
It is important to understand the perceptions of staff members who will be implementing the expected integration of mental health and substance use services into primary care. Surveys were administered to mental health/substance use disorder (MH/SUD) staff, support staff (SS), and primary care providers (PCPs) from three organizations (seven sites) that were participating in an initiative to promote the integration of MH/SUD services into primary care in Kern County, California. Results suggest that integration and MH/SUD services are highly valued among all staff types, and that staff are uniformly interested in further MH/SUD training. However, there were significant differences in staff perceptions. MH/SUD staff and services were valued by PCPs more than MH/SUD staff perceived being valued by PCPs, and MH/SUD staff were less likely to agree that communication with PCPs was good. Information seemed to flow better from MH/SUD staff to PCPs than in the other direction.
