Mental health reform was introduced as a public-sector policy response to identified deficiencies in the mental health services system. The reform agenda, which is underway in most provinces/territories, calls for greater accountability to mental health consumers, their families, and other stakeholders. This paper summarizes the major policy goals (which are the cornerstones of mental health reform) and suggests a series of high-level indicators to assess performance toward achieving these goals. Issues in the selection and measurement of performance indicators as markers of key goals are discussed. The proposed indicator set, while not a comprehensive framework, can provide a multi-dimensional appraisal of mental health system performance and help keep reform on course.
