To inform the development of a pan-Canadian Mental Health and Addictions (MHA) performance measurement framework, we undertook a rapid review of the recent Performance Measurement (PM) literature and solicited input from 20 MHA policy and measurement experts. Six key steps for framework development were identified: recognizing and acknowledging key issues, developing shared language and understanding of key concepts, defining overall scope, defining framework dimension/domains, selecting indicators and using systematic engagement and consultation processes with stakeholders. Subject matter experts underscored the need for a comprehensive engagement process which would honour multiple stakeholder viewpoints and attend to key issues in the codesign of features of the PM framework. Findings from this analysis may be used to inform a comprehensive stakeholder consultation process for the development of a pan-Canadian PM framework for MHA.
