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.The study objective was to investigate the extent to which
patient-generated PSFS items reflect ICF domains. This investigation was
an observational content validity study. METHODS: A total of 2,911 PSFS items
from 1,050 files for patients with musculoskeletal disorders were analyzed. The
data were from a random sample of participants in the Otago Outcome Measures
Project at 4 clinics of the School of Physiotherapy, University of Otago,
situated in 3 New Zealand cities. Patient-nominated PSFS items were categorized
and mapped with thematic analysis techniques to ICF components, chapters, and
categories. Subgroup analyses were conducted for body region of injury and age
ranges. RESULTS: All (100%) of the analyzed items could be mapped to the ICF.
Most patient-nominated items mapped to the activity component (80.0%), some items
mapped to the participation component (7.7%), other items were related to
impairment (7.4%), and the fourth group contained items that overlapped the
activity and participation components (4.9%). Similar results were found for each
of the 5 body regions and across age ranges in subgroup analyses. LIMITATIONS:
These results are limited to individual patients seeking musculoskeletal physical
therapy. Patient-generated PSFS items were investigated. CONCLUSIONS: The ICF
activity component was most commonly represented by patient-nominated PSFS items,
the participation component was moderately represented, and impairment was least
represented. Hence, the PSFS would complement impairment-based clinical outcome
measures.
