Single Case Research Methodology 3rd Edition

Single Case Research Methodology, 3rd Edition is a definitive reference for understanding and applying single-case research designs in educational, behavioral, and clinical settings. Edited by respected scholars Jennifer R. Ledford and David L. Gast, this edition builds on previous strengths while offering updated, clearer, and more practical guidance for modern research needs.

The book provides a thorough and technically rigorous explanation of single-case research methodology while remaining accessible to students and practitioners. It is designed to support readers at every stage of the research process—from learning foundational concepts to designing studies, interpreting results, and preparing professional research manuscripts.

A major strength of this text is its real-world applicability. The authors present a wide range of authentic single-case research examples involving diverse participants, including preschool children, K–12 students, university learners, and adults. These studies take place across varied environments such as classrooms, clinics, community programs, and healthcare settings, ensuring relevance across disciplines.

The book covers all major types of single-case research designs, including withdrawal designs, multiple baseline designs, alternating treatment designs, and changing criterion designs. Readers gain a deep understanding of experimental control, visual analysis, internal and external validity, reliability, and ethical considerations. Special attention is given to data interpretation and decision-making based on graphical analysis—an essential skill in single-case research.

Single Case Research Methodology is especially valuable for professionals in special and general education, school and clinical psychology, child development, neuropsychology, speech-language pathology, occupational therapy, physical therapy, recreation therapy, and social work. It serves equally well as a graduate-level textbook, a practitioner’s reference, and a guide for researchers preparing proposals, dissertations, journal articles, or grant applications.

The third edition enhances clarity and usability with improved organization, updated examples, and expanded discussions on contemporary research standards. Readers are guided in aligning single-case research with evidence-based practice and ethical research principles, making the book highly relevant in today’s accountability-driven educational and clinical environments.

Whether you are new to single-case research or an experienced researcher seeking a reliable reference, this book offers depth, precision, and practical insight. Its balance of theory and application makes it an indispensable resource for anyone committed to conducting high-quality single-case research and contributing meaningful evidence to the social, educational, and behavioral sciences.
