Composing a Core Set of Performance Indicators for Public Mental Health Care: A Modified Delphi Procedure

Public mental health care (PMHC) systems are responsible for the wellbeing of vulnerable groups that cope with complex psychosocial problems. This article describes the development of a set of performance indicators that are feasible, meaningful, and useful to assess the quality of the PMHC system in Amsterdam, the Netherlands. Performance indicators were selected from an international inventory and presented to stakeholders of the PMHC system in a modified Delphi procedure. Characteristics of indicators were judged individually, before consensus on a core set was reached during a plenary discussion. Involving stakeholders at early stages of development increases support for quality assessment.
