Responsive evaluation of integrated action (ria): a method for monitoring by stakeholder dialogues on health-related integrated action processes of integrated action to promote and protect health require a distinct method for monitoring and evaluation that is sensitive to the perceptions and experiences of different stakeholders and the often capricious and unpredictable course of events. Responsive evaluation is a method for participatory research in which the researcher actively builds on the information needs, expectations and capacities of the stakeholders. Goals consist of providing a balanced overview of the diversity of frames, expectations, values and assumptions, and facilitating mutual understanding. In collaboration with the health policy officers of the province north-brabant and an independent professional dialogue facilitator we developed, conducted and evaluated a responsive evaluation of integrated action (ria). In group interviews with a diverse representation of policy officers, we first mapped the activities of the 12 largest municipalities in the province that they associate with a ‘healthy city’. We then organised a stakeholder workshop based on the themes that resulted from the interviews. There the stakeholders identified current activities, enabling and disabling conditions for integrated action, and the political-administrative conditions for a healthy city. Afterwards stakeholders valued the responsive evaluation as a credible method for exchanging authentic stakeholder experiences, which has led to more support among the stakeholders and a diversity of spin off activities and consolidation of health considerations in other provincial policy documents.
