Chapter 1 identifies and discusses six types of EIP questions. If research hierarchies were to be developed for each of these types of questions, experimental designs would rank high on the ones about effectiveness, but would either be infeasible or of little value for the others. Qualitative studies would rank low on the ones about effectiveness, but high on the one about understanding client experiences.

Let's now look further at some types of research studies that would rank high and low for some types of EIP questions. In doing so, let's save the question about effectiveness for last. Because the fifth and sixth types of EIP questions – about costs and potential harmful effects – tend to pertain to the same types of designs as do questions of effectiveness, we'll skip those two so as to avoid redundancy. The point in this discussion is not to exhaustively cover every possible type of design for every possible type of EIP question. Instead, it is just to illustrate how different types of EIP questions imply different types of research designs and that the research hierarchy for questions about effectiveness does not apply to other types of EIP questions. Let's begin with the question: What factors best predict desirable and undesirable outcomes?
