Validity and reliability of Persian version of activities-specific balance confidence scale in patients with multiple sclerosis
Background and Aim: Multiple sclerosis is a chronic inflammatory disease of demyelinating lesions in the brain, spinal cord and optic nerve. One of the most debilitating symptoms of multiple sclerosis (MS) patients is impaired balance. Thus in people with MS, collecting information about the impact of impaired balance on life style and the disability which is being perceived by the patient is essential and its information cannot solely be achieved through any of balance and functional tests. The aim of this study was to assess the validity and reliability of Persian version of the Activities-specific Balance Confidence (ABC-P) scale in patients with MS.
Methods: A hundred and sixty two patients aged between 20 to 50 years old with MS disorder were examined. To analyze the data, Lawshe method, content validity ratio (CVR), content validity index (CVI), test-retest reliability, and internal consistency reliability were utilized.
Results: Intraclass correlation coefficient (ICC), and Cronbach's alpha coefficients were 0.93, 0.97, 0.96 and 0.97, respectively.
Conclusion: ABC-P scale has essential validity and reliability in people who are suffering from multiple sclerosis among Iranian society.
