Reliability and validity of the Turkish version of the Physical Activity Barrier Scale for people who are blind or visually impaired

Abstract

Purpose: The aim of this study was to investigate the reliability and validity of the Turkish version of the Physical Activity Barrier Scale (PABS) for individuals with visual impairment. Methods: People with low vision (n=53) and blind people (n=84), total137, were consisted of the present study. The physical activity barriers of the participants were evaluated with the PABS. The International Physical Activity Questionnaire (IPAQ-Long Form) was used to determine the physical activity level of the participants. Internal consistency was determined by using Cronbach’s alpha and test-retest reliability was determined by using intra-class correlation coefficient (ICC). Results: The mean age of the participants was 43.03±13.75 years and the mean body mass index was 26.11±4.77 kg/m2 11 . Cronbach’s alpha of the PABS was .933 for the test, and 0.894 for re-test measurements. Test-retest ICC values of the PABS varied between .563 and 0.950. The mean physical activity level of the participants was 4049.43±4956.59 minutes/week. There was no statistically significant correlation between the PABS and the IPAQ (p>0.05). Conclusion: There is currently no special questionnaire regarding physical activity and its barriers for visually impaired individuals in Turkey. The study showed the reliability of the Turkish version of the PABS for individuals with visual impairment.
