Book excerpt: The Practice of Research in Social Work introduces research methods as an integrated set of techniques for investigating the problems encountered in social work. This innovative text encourages students to connect technique and substance, to understand research methods as an integrated whole, and to appreciate the value of qualitative and quantitative alternatives. The text enables students to both critically evaluate research literature and to develop the skills to engage in research and practice evaluation. Each chapter shows how particular research methods have been used to investigate an interesting social work research question and content on research ethics and diversity is infused into each chapter. The goal of validity is introduced early in the text and used as an integrating theme throughout the book. Methods of particular concern in social work research are highlighted, with chapters devoted to group, survey, single subject, and qualitative designs. The text is lively and accessible, yet the coverage is thorough and up-to-date.
