The Counselor as Practitioner-Researcher: A Practical Guide to Research Methods is designed to help readers integrate a researcher's perspective and research methodology into their professional practice. Approaching practice as a practitioner-researcher not only facilitates the gathering of data and the drawing of useful conclusions, but also results in more ethical and effective practice decisions. Section I provides readers with an overview of the need and value of research in support of the counseling profession and as a basis for sound and successful practice decisions. In Section II, the fundamentals of quantitative, qualitative, and mixed designs are reviewed. Section III highlights specific designs and their value to the counselor as practitioner-researcher, including between group, within subject, action research, and case study designs. The text concludes with an extensive case illustration of counselor research and the steps necessary to developing a specific research plan. The Counselor as Practitioner-Researcher assists those in training and those in practice to not only become informed consumers of research, but also "doers" of research as it guides their practice decisions, affords measures of accountability, and supports program evaluation.
