...Our objective in this article is to identify the problems with the design of studies to evaluate both the process of ethics and its effectiveness, and to propose potential solutions. We explore the nature of ethics consultation as an intervention, identify obstacles to addressing the main components of research design (excluding measurement, which is discussed in the article by Ellen Fox and M. Arnold in this issue, "Evaluating outcomes in ethics consultation"), propose potential solutions to these challenges, and conclude with tentative agenda for research.
