MAPping Los Angeles County: taking an evidence-informed model of mental health care to scale.

We describe the scaling up of an evidence-informed model of care, Managing and Adapting Practice (MAP) in Los Angeles County, California. MAP complemented an array of evidence-based programs selected by the county as part of a large system reform effort designed to improve care for children and adolescents. In addition, we discuss the MAP model for training therapists and present data both on how the training model performed and on the outcomes of youths treated by therapists trained in MAP. We examined the success of two different training pathways for MAP therapists: (a) national training model and (b) MAP agency supervisor model (i.e., train the trainer). We also examined utilization of MAP and outcomes of clients served by MAP. Both the national training and MAP agency supervisor model were successful in producing MAP therapists in a timely fashion and with acceptable competency scores. Furthermore, a large number of clients were receiving MAP services. Finally, outcomes for youth treated with MAP were strong, with effect sizes ranging from .59 to .80 on the Youth Outcome Questionnaire. These data support the notion that scaling up a mental health services approach in a system can be achieved through a strong and broad partnership among relevant stakeholders, can involve a train-the-trainer model, and can result in strong outcomes for clients.
