Although not all authors agree on the exact number of steps and how to label them, they generally agree that the number is around five or six. More important, there is wide agreement as to what is to be done overall, regardless of the number of steps used to order them. In this chapter, five main steps in the EIP process are discussed in more detail. The chapter ends with a discussion of various daunting feasibility constraints that you are likely to encounter in trying to implement these EIP steps in the real world of practice.

      Before you start searching for evidence, you need to know what question you are trying to answer. Chapter 1 describes six common types of EIP questions. One of the most common of the six questions pertains to ascertaining which interventions, programs, or policies have the best evidence supporting their effectiveness.

      Suppose, for example, that you are planning to establish a residential treatment facility for physically or sexually abused girls who have emotional or behavioral problems, and you need to decide which treatment modalities to employ. Your EIP question might inquire as to which treatment modalities have the best evidence supporting their effectiveness with girls who share the projected characteristics of your clients. Alternatively, you might have reason in advance to suspect that one or more particular modalities will be most effective based on what you have read or heard about it from a theoretical standpoint. For example, colleagues involved in a similar program elsewhere might rave about the great success they've experienced using eye movement desensitization and reprocessing (EMDR). Colleagues in another program might claim to have had little success with EMDR and much more success with exposure therapy. Perhaps you've read clinical books on both modalities, and both look equally promising to you from a clinical standpoint. Consequently, instead of asking a broader question about the effectiveness of the gamut of possible treatment modalities, you might narrow your search to the question of whether EMDR or exposure therapy is more effective with the types of clients you plan to treat.

      Before you begin to search the evidence, it can be helpful to lay out your question – whether you are using a PICO framework or not – so that you can think about the key search terms that you could use before you are in the thick of the search. Especially helpful is to think about synonyms that represent the same key concepts in your question. For example, different studies might refer to children aged 12–16 as children, youth, or young adolescents. If you don't think about these synonyms, you may miss studies that just use different language to mean the exact same thing.

P Patient (or client), population, or problem This is the part of the question where you would specify your client, the problem or need that you are addressing through services, and the key characteristics that you think might have an important impact on the intervention or assessment tool that you choose. For example, some interventions have demonstrated different effects across different racial or ethnic populations, and some assessment instruments have not been developed to be used for clients with varied languages and cultures. This is important information to consider as you search for research and you consider the relevancy of the findings for your client.
IC Intervention comparison For example, you may be trying decide between using two different parent training interventions – or you may be thinking about adding a new depression screening instrument versus using clinical interviews to identify clients who need depression treatment. Choosing an intervention and a comparison is a good reminder that EIP questions involve making a practice decision; therefore, there should be at least two different options between which you will be deciding. The comparison isn't always an active treatment. You might simply ask whether the intervention you're interested in is better than not intervening at all. Either way, the question should have real implications for directing what you actually do in practice.
O Outcome This is what you're hoping to see change as a result of your intervention or assessment efforts. You may be hoping to reduce child behavior problems among your clients, or more accurately detect moderate to severe depression. It's helpful to be specific and avoid broad outcomes that are hard to assess such as general wellbeing.

      Most of the sites, however, will not enable you to read the original research studies yourself. Instead, they'll present summaries of the research and perhaps offer EIP guidelines. In Chapter 8 we describe a rigorous approach to searching and synthesizing research called a systematic review. That chapter describes which attributes to look for in a research review to give you a sense of the quality of the review.
