To respond to the renewed focus by the occupational therapy profession upon occupation, the fifth edition of Activity Analysis and Application has been updated and renamed to reflect this latest emphasis. While Activity Analysis: Application to Occupation, Fifth Edition maintains the sequential process of learning activity analysis, this step-by-step approach now helps students analyze activity for the purpose of optimizing the client's occupational performance. Gayle Hersch, Nancy Lamport, and Margaret Coffey successfully guide students through the development of clinical reasoning skills critical to planning a client's return to meaningful engagement in valued occupations. The authors utilize a straightforward teaching approach that allows students to progress developmentally in understanding both the analysis and application of activity to client intervention. The Occupational Therapy Practice Framework: Domain and Process, with a prominent focus on occupation as this profession's philosophical basis for practice, has been incorporated in the updated forms and explanations of the activity analysis approach. Activity Analysis: Application to Occupation, Fifth Edition is a worthy contribution to the professional education of occupational therapists in furthering their understanding and application of activity and occupation. The features include: the newly titled Client-Activity Intervention Plan that synthesizes the activity analysis into client application; objectives at the beginning of each unit; discussion questions and examples of daily life occupations; and a Web site including 5 forms where students and practitioners can download and print information for class assignments and clinical settings.
