Nearly 600 instruments are reviewed in this new edition of occupational therapy's classic publication, includÂing many developed by occupational therapists. An international team of academicians, clinicians, researchers, and advanced-degree candidates working in various praÂtice arenas collaborated on this update. The assessment profiles--which include title, authors, format, purpose, population, time required to administer, setting or position, materials or tools, brief description, interpretation, reliability and validity, source, additional references, cost, and sample--will be useful to clinicians and students, who must choose appropriate tools for clinical practice; to educators, who select assessment procedures for the classroom; and to researchers, who will find instruments that are designed for research purposes or will benefit from further investigaÂtion. This edition includes a matrix of all assessments, showÂing content areas and age ranges of each instrument.
