Now in a new edition, this accessible, engaging textbook presents step-by-step guidelines and useful examples for each phase of practice, from assessment to intervention to evaluation. Its key focus remains on emphasizing the importance of critical thinking in making sound practice decisions. Eileen Gambrill - a pioneer of the evidence-based practice movement - skillfully shows students how to ask the right questions, search for reliable answers, and rigorously evaluate the results. Designed to equip students with vital practice knowledge and skills as well as an understanding of the larger picture in which social workers practice, this is much more than a "how-to" compilation. It establishes a sound conceptual framework that considers political, social, economic, empirical, and ethical issues, with equal attention to helping to solve client problems and bolster client strengths. Filled with practical advice, real-life scenarios, thought-provoking exercises, and straightforward guidance, this problem-solving practice guide prepares students to advocate for clients by being, above all, good decision makers.
