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:
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 volume represents no less than a quantum leap in the application of single-case designs to the rehabilitation setting. With crisp writing and meticulous scholarship, Tate and Perdices have given us an instant classic on an increasingly important route to evidence-based practice. They unpack the confusing terminology, explain all of the design variations, and offer a valuable ten-step approach to implementation. This book will fill a much-needed niche in clinics, classrooms, and laboratories the world over." - Tessa Hart, Moss Rehabilitation Research Institute, USA
"Tate and Perdices have written a comprehensive, crystal clear guide for how to conduct and analyze SCED studies specific to the field of neurorehabilitation. This book will be my go to resource for designing and evaluating SCED studies and teaching this methodology to my students. Without a doubt, this text will elevate the evidence-base for interventions designed to improve the lives of people affected by neurological disease and injury." - McKay Moore Sohlberg, University of Oregon, USA
"Several ingredients make this book a valuable guideline for applied researchers: advice on enhancing internal and external validity when planning and conducting studies that can contribute to identifying evidence-based practices, overview of the myriad of data analytical options, and suggestions for comprehensive reporting. The practical approach is boosted by the integration of all these aspects in a ten-step illustration." - Rumen Manolov, University of Barcelona, Spain
"Tate and Perdices have produced a text that captures their years of experience and expertise, and they clearly set the standard for applying single-case experimental designs in the context of neuropsychological rehabilitation. The text provides in-depth discussion of scientific methodology that informs clinical research, but goes beyond that to provide practical advice and direct guidance that will allow clinicians to evaluate the effectiveness of their treatments and inform their future practice. This work is a unique contribution to the field for scientist-practitioners." – Keith Cicerone, JFK Johnson Rehabilitation Institute, USA

Appendix: Summary Components of Selected Neurorehabilitation Studies
Neuropsychological rehabilitation is influenced by a number of fields both from within and outside psychology. Neuropsychology, behavioural psychology and cognitive psychology have each played important roles in the development of current rehabilitation practice, along with findings from studies of neuroplasticity, linguistics, geriatric medicine, neurology and other fields. Neuropsychological Rehabilitation: A Modular Handbook series reflects the broad theoretical base of the discipline, and is not confined to one conceptual framework. Although each volume is based on a strong theoretical foundation relevant to the topic in question, the main thrust of the majority of the books is the development of practical, clinical methods of rehabilitation arising out of this research enterprise.
The series is aimed at neuropsychologists, clinical psychologists and other rehabilitation specialists such as occupational therapists, speech and language pathologists, rehabilitation physicians and other disciplines involved in the rehabilitation of people with brain injury.
