Asking questions in the solution space: methodological issues in evaluating equity.

This paper presents an overview of some core methodological issues in improving the evaluation of health equity interventions. It argues that evaluation can play a central role in the solution space if it takes a futures orientation and develops adaptive approaches. It makes the case that purpose must drive method and that clarity in values is central. It suggests a process to rethink health equity interventions, reshape policy based on evaluation at the systems level, and reform evaluation of health equity so that it has the capacity to adapt and to more realistically reflect the dynamic and changing nature of systems.
