In Mixed Methods Design in Evaluation, the first volume of SAGE's Evaluation in Practice Series, best-selling author Donna M. Mertens explores the meaning of mixed methods evaluation, its evolution over the last few decades, and the dominant philosophical frameworks that are influencing thought and practice in the field today. Four chapters explore evaluation of the effectiveness of interventions, development of instruments, systematic reviews, and policy evaluations, while an additional chapter covers evaluation approaches often required in specific contexts including gender responsive evaluations, needs assessment, and evaluations in conflict zones. Practical in nature, the book guides readers' thinking about the design of mixed methods evaluations through the use of illustrative examples and explanations for further applications.
