Validation of the comprehensive ICF core set for multiple sclerosis from the perspective of physical therapists.

BACKGROUND

The Comprehensive ICF Core Set for Multiple Sclerosis (MS) is an application of the International Classification of Functioning, Disability and Health (ICF) and represents the typical spectrum of problems in the functioning of people with MS.

OBJECTIVES

The objective of this study was to validate the Comprehensive ICF Core Set for MS from the perspective of physical therapists.

DESIGN

A 3-round survey based on the Delphi technique was used.

METHODS

Physical therapists experienced in the management of MS were asked about problems and resources of people with MS as well as environmental aspects treated by physical therapists (eg, use of assistive devices, support). Statements were linked to the ICF and compared with the Comprehensive ICF Core Set for MS.

RESULTS

Eighty physical therapists from 23 countries mentioned 2,133 issues that covered all of the ICF components. Two hundred thirty-eight ICF categories were linked to the statements. Forty-six categories in the Comprehensive ICF Core Set for MS were confirmed by physical therapists at the same level or a more specific level of classification. Nineteen additional ICF categories were reported by at least 75% of the participants.

CONCLUSIONS

The results of this study support the content and face validity of the Comprehensive ICF Core Set for MS. Areas of functioning and health that physical therapists believe should be assessed were identified. The findings of this study as well as the results of completed and ongoing validation studies will further elucidate the validity of the Comprehensive ICF Core Set for MS from different perspectives.
