Well-known and respected author, Gary Kielhofner, has thoroughly revised his groundbreaking text that compares and contrasts eight well-known models. He uses numerous diagrams to show the practical aspects of occupational therapy theory and to help students understand the similarities and differences between the models. He critically re-evaluates existing models and extensively examines all associated research to determine whether or not they still warrant the status of model. Chapters are well organized and are supported by extensive referencing.
