Single Case Research Designs

Kazdin's text is a notable contrast to the quantitative methodology approach that pervades the biological and social sciences. The methodology in Single-Case Reasearch Designs focuses on a widely applicable methodology for evaluating interventions, such as treatment, or psychotherapy, using applied behavior anlaysis. However, this revision aims to encompass a broader range of research areas that utilize single-case designs. The text will convey the pertinence of this research methodology to disciplines ranging from psychology and medicine to business and industry. The first edition of this book, which was published in 1982, still sells a steady amount of copies today. The fact that professors continue to use the first edition of this book more than twenty years after it was published is a testament to the quality of information, organization, and narrative throughout the text. The possibility of a revision has professors excited that they can expose their students toa well-written, clear, and updated text that will reflect the current status of single-case research.

Originally published in 1992, the editors of this volume fulfill three main goals: to take stock of progress in the development of data-analysis procedures for single-subject research; to clearly explain errors of application and consider them within the context of new theoretical and empirical information of the time; and to closely examine new developments in the analysis of data from single-subject or small n experiments. To meet these goals, this book provides examples of applicable single-subject research data analysis. It presents a wide variety of topics and perspectives and hopes that readers will select the data-analysis strategies that best reflect their methodological approaches, statistical sophistication, and philosophical beliefs. These strategies include visual analysis, nonparametric tests, time-series experiments, applications of statistical procedures for multiple behaviors, applications of meta-analysis in single-subject research, and discussions of issues related to the application and misapplication of selected techniques.

Written for advanced undergraduate- and graduate-level courses in Single Case or Single Subject Research Designs, and Research Methods in Educational and Community Settings. A practical nuts-and-bolts how-to guide to carrying out single case research designs, this new textbook is focused squarely on single case research in educational and community settings, emphasizing practice versus theory. The authors have put together a unique guidebook for courses in single case and single subject research for educational and community settings, and conceptualizes the background underlying this research approach, walking readers through a step-by-step approach to the components involved in doing such research. The text covers single case designs with a brief historical background on the development of these design approaches; some of the basic logistical barriers to and solutions for carrying out research in applied settings; and nuts-and-bolts procedures of carrying out such research with regard to designing and implementing measurements systems, choosing appropriate designs, and graphing and analyzing data. In addition, the text covers the basics of disseminating research via various professional outlets such as conference presentations and journals for researchers and practitioners. The tables and graphics included list step-by-step procedures for carrying out various data collection and research design strategies, offering concise summaries of some key features of the main procedural elements of single case research, and a guideline to crucial features and concepts. Written for a broad range of educational and other human services professionals, including teachers (general and special education), school psychologists and counselors, social workers, communication disorders specialists, and recreation, occupational, and physical therapists, this new "how-to" textbook fills a gap in the market for a single case, single subject research design guide focused on research in educational and community settings, with a strong emphasis on practice versus theory. Frequent, significant use of tables and other graphics gives concise illustrations and summaries of the critical features under discussion. Featured throughout every chapter. Tables with step-by-step descriptions of how to implement the various stages and procedures of the design(s) are featured in chapters on specific designs (e.g., withdrawal/reversal designs, multiple baseline/multiple probes designs). These tables help to further illustrate and summarize the key steps in design implementation. Many examples of graphed data from published studies are incorporated throughout most of the chapters, providing an array of examples of how to graph data, how to analyze data, the different types of experimental single case designs, and more.

This text ntroduces readers to the history, epistemology, and strategies of single-case research design. The authors offer concrete information on how to observe, measure, and interpret change in relevant outcome variables and how to design strategies that promote causal inferences. Key Features Includes case vignettes on specific single-case designs Describes clinical and applied case studies Draws on multiple examples of single-case designs from published journals across a wide range of disciplines Covers recent developments in applied research, including meta-analysis and the distinction between statistical and clinical significance Provides pedagogical tools to help readers master the material, including a glossary, interim summaries, end-of-chapter review questions, and activities that encourage active processing of material. Intended Audience This text is intended for students and practitioners in a variety of disciplines—including psychology, nursing, physical therapy, and occupational therapy—who are increasingly called upon to document the effectiveness of interventions.

This book is a practical resource designed for clinicians, researchers, and advanced students who wish to learn about single-case research designs. It covers the theoretical and methodological underpinnings of single-case designs, as well as their practical application in the clinical and research neurorehabilitation setting. The book briefly traces the history of single-case experimental designs (SCEDs); outlines important considerations in understanding and planning a scientifically rigorous single-case study, including internal and external validity; describes prototypical single-case designs (withdrawal-reversal designs and the medical N-of-1 trial, multiple-baseline designs, alternating-treatments designs, and changing-criterion designs) and required features to meet evidence standards, threats to internal validity, and strategies to address them; addresses data evaluation, covering visual analysis of graphed data, statistical techniques, and clinical significance; and provides a practical ten-step procedure for implementing single-case methods. Each chapter includes detailed illustrative examples from the neurorehabilitation literature. Novel features include: A focus on the neurorehabilitation setting, which is particularly suitable for single-case designs because of the complex and often unique presentation of many patients/clients. A practical approach to the planning, implementation, data analysis, and reporting of single-case designs. An appendix providing a detailed summary of many recently published SCEDs in representative domains in the neurorehabilitation field, covering basic and instrumental activities of daily living, challenging behaviours, disorders of communication and cognition, mood and emotional functions, and motor-sensory disabilities. It is valuable reading for clinicians and researchers in several disciplines working in rehabilitation, including clinical and neuropsychology, education, language and speech pathology, occupational therapy, and physical therapy. It is also an essential resource for advanced students in these fields who need a textbook for specialised courses on research methodology and use of single-case design in applied clinical and research settings.

This is the first book to fully explain single-case research in the context of sport and exercise. Starting with first principles, it offers a comprehensive introduction to the single-case research process, from study design to data analysis and presentation.

In this anticipated new edition of Single Case Research Methodology, David L. Gast and Jennifer R. Ledford detail why and how to apply standard principles of single case research methodology to one’s own research or professional project. Using numerous and varied examples, they demonstrate how single case research can be used for research in behavioral and school psychology, special education, speech and communication sciences, language and literacy, occupational therapy, and social work. This thoroughly updated new edition features two entirely new chapters on measurement systems and controversial issues in single subject research, in addition to sample data sheets, graphic displays, and detailed guidelines for conducting visual analysis of graphic data. This book will be an important resource to student researchers, practitioners, and university faculty who are interested in answering applied research questions and objectively evaluating educational and clinical practices.
