The last decade has experienced a substantial increase in the development of peer-provided services for adults with serious mental illness, yet empirical evidence supporting these interventions unfortunately lags behind their rapid proliferation. The following report from the Yale Program for Recovery and Community Health contains findings from a multi-pronged naturalistic evaluation of the PeerLink Pilot project, which focused particularly on individuals with a history of recurrent hospitalizations in Wisconsin and Tennessee from December 2009 through August 2010. The aims of the evaluation were to measure the outcomes of the pilot program and its impact on the lives of people with mental illness, as well as to gain a further understanding of the experiences of both peers and clinical staff involved in this process. PeerLink-Evaluation-Final-Yale-Report-091812
