The Second Edition continues and expands upon the approach that made the first edition an international bestseller. It includes sections and chapters on: the analysis of methodological advances in conducting research in culturally complex communities; coverage of electronic resources now available to researchers and evaluators; an additional emphasis on program evaluation; and, a new chapter on mixed methods research. Each chapter carefully explains a step of the research process from literature review to analysis and reporting. Additionally, sample studies and abstracts are included in each chapter to illustrate the concepts discussed in that section of the book.
