Master's level providers in health service psychology: An idea that has come and passed, and now must come again

High rates of mental disorders persist globally, resulting in substantial burden for individuals, their families, and society. Although health service psychology (HSP) has much to contribute to the effort to reduce the burden of mental disorders, doctoral-level HSP providers are unlikely to meet the demand for services over the next decade. The vast majority of the mental health workforce is licensed at the master's level, yet the doctorate has remained the requirement for entry-level practice of HSP. The available evidence, however, suggests that the level of clinical training involved in doctoral education is not necessary to address common mental disorders. Now that the American Psychological Association has finally embraced accreditation of master's programs in HSP, an opportunity exists to educate and train the next generation of providers to effectively and efficiently address the persistent burden of mental disorders.
