Exploring clinician-reported assessments of capacity and performance qualifiers in the ICF: a scoping review.

The review only included studies that strictly followed the original ICF definitions for capacity and performance. This meant excluding many common clinical tools, like the Barthel Index or Functional Independence Measure, which may be used in practice but do not operationalize these constructs in the exact way the WHO defines them. The search was limited to English-language publications and excluded studies involving participants under 18 years old. The concept of 'clinician-reported assessment' (ClinRA) is a new term introduced by the authors and has not been validated in previous research. Because the evidence base was so small, the review could not provide a comprehensive picture of how these qualifiers are used in real-world clinical settings outside of research studies.

The authors declared that they received no financial support for this work or its publication.

Do not assume that using standard clinical tests automatically allows you to assign valid ICF capacity or performance qualifiers. The review found that the methods used in the few existing studies were inconsistent, rarely validated, and often ambiguous about what was actually being measured.
