This thoroughly updated fourth edition of Clinical Research in Communication Disorders: Principles and Strategies remains an instrumental resource for courses on research methods and design in communication disorders. The book is separated into three key sections: science and the scientific methods, clinical research designs, and doing, reporting, and evaluating research. Together, these sections provide thorough coverage of both the single-subject and group design strategies along with issues of measurement; philosophy of science; ethics of research; and planning, conducting, and reporting research. Instructors and students in communication sciences and disorders will appreciate the text's comprehensive coverage of scientific methods, group and single-subject research designs, report writing, and ethics of research in a single source.

Salvatore, PhD * A new chapter on statistical analysis of research data, including several statistical techniques for single-subject research data, meta-analysis of both group and single-subject studies * Updated criteria for visual analysis of single-subject research data * New sections on translational research, qualitative research, and mixed methods research * Descriptions of additional research designs not included in the previous edition (e.g., the regression discontinuity design) * Updated information on research ethics and review of fraudulent biomedical research * Web-based sources that monitor research fraud and recalled studies * Updated and expanded references throughout.
