Mapping Patient-Specific Functional Scale (PSFS) items to the International Classification of Functioning, Disability and Health (ICF).

Background: The International Classification of Functioning, Disability and Health (ICF) provides a common framework for clinical outcome measurement. Because the Patient-Specific Functional Scale (PSFS) is widely used for documenting change over time in individual patients receiving musculoskeletal physical therapy, investigation of the extent to which PSFS items reflect the ICF is needed.

Objective: The study objective was to investigate the extent to which patient-generated PSFS items reflect ICF domains.
