Designed to help students develop skills in evaluating research and conducting studies, the Third Edition of this popular text makes principles of evidence-based practice come alive through illustrations of actual social work research. The authors introduce students to the study of research in social work and to the contributions made to our understanding of what is effective social work practice. In addition, the authors have designed this edition to directly and indirectly help students achieve the six core competencies identified by CSWE as essential to competency-based education. --Publisher description.
