Principles of evidence-based practice come alive through illustrations of actual social work research in this Second Edition of Rafael J. Engel and Russell K. Schutt's innovative The Practice of Research in Social Work. The authors introduce research methods as an integrated set of techniques for investigating the problems encountered in social work, directly linking each topic to issues associated with ethics, diversity, and evidence-based practice. Enabling students to critically evaluate research literature and develop the skills to engage in research and practice evaluation, the book emphasizes methods of particular concern in social work research and devotes chapters to group, survey, single subject, and qualitative designs.
