You and your students will love this classic text -- now in its 50th year! Completely revised and updated for the ninth edition, Willard and Spackman's Occupational Therapy continues to set the standards for the field. This major revision has been completely reorganized and refocused down to the very last page, with no chapter left untouched. The reader will appreciate the text's close examination of the professional development process and the unprecedented coverage of evaluation and treatment. New chapters cover evaluation of performance contexts, treatment of performance contexts, and the psychometric properties of assessement instruments. New first person narratives by people with disabilities help readers understand the patients' perspectives and apply them to their own career experiences.
