Validation of the Comprehensive ICF Core Set for Multiple Sclerosis: A Turkish clinical perspective.

Abstract

Objectives: The aim of this study was to evaluate the results of the construct validity of the Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set for Multiple Sclerosis (MS) and to identify the impact of MS on specific health domains according to the ICF categories in Turkish individuals.

Patients and methods: Between December 2011 and December 2012, a total of 150 individuals with MS (69 males, 81 females; mean age: 39.8±8.0 years; range, 19 to 52 years) who were diagnosed by a neurologist at least six months previously were included. The Comprehensive ICF Core Set for MS was used to assess functioning, disability, and environmental factors in all participants. The Spearman correlation coefficient was used to determine construct validity of the ICF Core Set between the ICF components and disease-specific and general measurements.

Results: The most frequently coded impairments in the body functions component were b280 sensation of pain, b134 sleep functions, b1301 motivations, and b740 muscle endurance functions. The most frequently coded impairments in the body structures component were s110 structure of brain, s120 spinal cord and related structures and s750 structure of lower extremity. A significant problem was documented in 47 of the 53 categories of the activities and participation. Of the 38 categories in the environmental factors, 23 were identified as a facilitator, while 12 categories were identified as a barrier. All body function, structure, activities and participation and environmental factors categories showed a significant correlation with disease-specific and generic measures.

Conclusion: Based on these results, the ICF Core Set may help to determine major facilitators or barriers to functioning and disability and a targeted rehabilitation approach in patients with MS.
