Creating a prepared mental health workforce: comparative illustrations of implementation strategies.

Background: Psychotherapy implementation must contend with the task of preparing a mental health workforce to provide the highest quality services to as much of a service population as possible, in high-income as well as low-to-middle income countries.

Objective: We outline general challenges and solutions and investigate how well various implementation strategies would fit a clinical population.

Methods: Using a data set from a prior cluster randomised trial with a clinically diverse population and 33 intervention practices, we presented multiple illustrations comparing the ability of different implementation strategies to serve youth and families with procedures in which service providers were trained.

Findings: A series of survival functions demonstrated that many common implementation strategies are unlikely to create a prepared workforce, given the large and diverse number of practices needed to be mastered by providers.

Clinical implications: 'Benchmark' solutions that afforded superior coverage of the service population could be supported through paced learning approaches (ie, training interventions a little at a time) using extensible, modular intervention designs.
