Recently, there has been increased interest in consumer-provided mental health services. Two models have been proposed: One emphasizing full independence from professional services, and one in which consumers work within the mental health system. In this paper we describe Vet-to-Vet, a consumer-professional partnership model in which consumer services are embedded in a mental health system. We describe the advantages of this approach and barriers to implementation of other models. Vet-to-Vet has several unique elements, developed and implemented by consumers with professional consultation and supervision. We believe that consumer-partnership models of consumer-provided mental health services have potential for minimizing implementation barriers and for maximizing long-term sustainability. (Authors)
