Issues in assessment of psychosocial components of function.

For occupational therapy to provide a holistic view of meaningful activity, we must understand the relationship between physical, psychological, and social variables, especially as they affect our psychosocial evaluations and treatment. Existing definitions of psychosocial variables are unclear and, for occupational therapy practice, must be linked to activity and occupational performance. Occupational therapists need to become more educated about the uses and limitations of psychosocial instruments and to develop new instruments that address the central tenets of occupational therapy by focusing on whether or not a person is able to do what is necessary and fulfilling. Further, understanding what is meant by meaningful activity and what people need to accomplish it will advance our effectiveness in occupational therapy assessment and practice.
