Instrument Development in Occupational Therapy describes an instrument development study that will enhance your understanding of the interview process and contribute to the availability of truly useful clinical interviews. This important book examines content and concurrent validity and development of the Assessment of Occupational Functioning (AOF) and carefully compares the AOF with a similar instrument, the Occupational Case Analysis Interview and Rating Scale (OCAIRS), to discover the similarities and strengths of these instruments. The study yields clear, data-based implications for the AOF second revision and directions for further research. The authors also place this research in the context of other formal interviews, comment on the use of standardized patient evaluations in psychosocial practice, and show the use of the AOF.
