This article presents the results of a Delphi group to identify the dimensions of an evaluation framework for collaborative mental health care (CMHC) in Latin America. A three-round Delphi process was implemented with 26 experts from Latin America and Canada to identify main areas of consensus, as well as disagreements, about the importance and feasibility of potential evaluation dimensions previously identified in Mexico, Nicaragua and Chile. Participants validated 40 evaluation dimensions. They strongly endorsed a comprehensive evaluation framework for CMHC in Latin America. This study represents a solid foundation for developing an evaluation framework for CMHC.
