This social work research methods text is written in an accessible, reader-friendly style. Its paperback format also makes it less expensive than most competitive texts on the market. The authors are social workers and educators who understand the realities of social work practice. They have included many examples of how research can be used to inform social work practice. The text is ideal for a one-semester or quarter research methods course for undergraduate or graduate students who have little or no prior knowledge of research. The Sixth Edition describes and illustrates the contributions of both quantitative and qualitative research methods to evidence based practice. They are presented as complementary and necessary to an understanding of human behavior and the problems that social workers must address.
