The Handbook Of Evidence Based Practice In Communication Disorders

Where to find it and how I actually use it day to day

The Handbook of Evidence-Based Practice in Communication Disorders is a reference text edited by Rosanna K. Prutting and Marcia L. Harris, published by ProEd. It sits somewhere between a textbook and a clinical manual, aimed at speech-language pathologists and audiologists who need to justify their methods rather than just defaulting to whatever they learned in grad school. You can order it through ProEd directly, Barnes and Noble, Amazon, or find institutional access through university libraries. Most people get it through their school library or departmental bulk purchase. I bought a used copy off AbeBooks for about thirty dollars around 2009 because my supervisor told me I should stop justifying treatment plans with anecdotes and start referencing actual clinical frameworks. I kept meaning to read it cover to cover but never did. Nobody reads it cover to cover. What I do is flip to the chapter on evidence hierarchies when a parent or insurance adjuster asks why I'm doing something a certain way, and then I go back to the case study examples to figure out how to document the match between the evidence and my clinical reasoning. The book is organized into sections that walk you through the three pillars of evidence-based practice: best available research evidence, clinical expertise, and client/patient values and preferences. That third pillar is where most people trip up, including me when I first started using it seriously. The handbook spends time on each pillar and then spends the rest of the book showing how they intersect in real clinical scenarios. It's not a step-by-step protocol. It's more of a decision-making framework you have to adapt to your own caseload.

One thing the book doesn't make clear enough is how much time it actually takes to do this properly when you're carrying a full caseload. I used to think I could spend ten minutes per chart entry pulling evidence to back my approach. In practice it takes closer to twenty-five to forty minutes if you're doing it right, which means you either need administrative support time or you accept that documentation quality will slip when things get busy. That's a real bottleneck I still haven't figured out how to solve cleanly.

How to actually apply the framework without losing your mind

Start by identifying the clinical question you need to answer. Not the intervention you want to do. The actual question. Something like whether direct or indirect family-mediated intervention produces better outcomes for children with developmental language disorder in the school-age population. Then you search for evidence using standard databases—CINAHL, PubMed, the ASHA National Center for Evidence-Based Practice in Communication Disorders. The handbook points you toward those resources but doesn't give you a ready-made search string for every possible question. Here's the part nobody tells you: the hierarchy of evidence in the handbook uses a modified version of the classic levels, and it weights clinical expertise heavily alongside research. That's intentional, but it also means two clinicians looking at the same evidence can reach different conclusions and both be correct within the framework. I ran into this exact problem when a colleague and I disagreed on whether to use a phonological awareness intervention for a child with co-occurring language impairment. We each pulled from the same chapters in the handbook and came to opposite recommendations. The workaround was straightforward once I stopped treating the handbook like a rulebook and started treating it like a reasoning tool. We documented our individual weightings of each evidence source, compared them side by side, and the difference came down to how we each valued the single-case experimental design studies versus the systematic reviews. Once we made that explicit, we had a productive conversation instead of a stalemate. The handbook also covers how to assess the quality of evidence you find. It walks through critical appraisal tools adapted for speech-language pathology contexts. I found myself skimming those sections initially because they felt generic, but the section on evaluating single-case designs turned out to be the most useful part of the entire book for my practice. Most of the evidence in our field comes from single-case or small-N studies rather than large randomized trials, and the appraisal framework the handbook provides is specifically tuned to that reality. Standard medical evidence hierarchies downrank that study design almost immediately, which makes them nearly useless for us unless you know how to evaluate them properly.

Where the handbook falls short and what I do instead

The handbook is thorough but dated. The editions I've seen reference research up through the mid-2000s to early 2010s depending on which printing. That's a genuine limitation because the evidence base in communication disorders has moved fast, especially around early intervention, telepractice, and autism spectrum disorder. If you're relying solely on this book you'll be working with evidence that's at least a decade old in some chapters. I pair it with quarterly searches of the ASHA perspective articles and recent systematic reviews to keep current. The handbook gives you the framework; the journal literature gives you the newest data points. Another gap: the handbook assumes you have access to a research library and time to conduct proper evidence searches. If you're in private practice with limited administrative help and no institutional subscription access, that assumption breaks down pretty quickly. I've seen colleagues who couldn't afford journal subscriptions just pick interventions based on whatever conference presentations they'd seen, which defeats the whole purpose. The workaround is using open-access repositories like PubMed Central and the ASHA NCEBP website, which free many of the primary sources up without a subscription.

What to focus on if you only read three sections

The chapter on integrating client and family values is worth more than its page count. It's where the handbook becomes actually usable in a busy clinic rather than just theoretically sound. The next two sections I'd prioritize are the evidence hierarchy discussion specific to communication disorders and the clinical decision-making case examples. Everything else is reference material you'll consult when a specific situation arises. The handbook isn't a quick read and it's not a replacement for your own critical thinking. It's a scaffolding tool that gets you out of the habit of justifying everything with tradition and into the habit of being explicit about why you chose what you chose. That shift alone is worth the price of the book. The rest is up to you to maintain and update as the evidence base grows.
