Book excerpt: "Thyer and Myers have written an easy-to-read primer on the topic of empirically evaluating the outcomes of social work practice. This resource, for social work students--graduate and undergraduate-- and for social work practitioners, presents outcome studies using both group-research and single-case designs. Unlike other books dealing with the topic of evaluating practice which use theoretical cases, Thyer and Myers use real-life examples of evaluating social work practice, ranging from those fairly low on the scale of internal validity to those that are pretty rigorous. The book begins with a refresher on evaluation research, provides a balanced approach to both single-system and group-evaluation designs, and closes with a discussion of ethical issues, myths, misconceptions, and practical cinsiderations in evaluation"--Back cover.
