| Abstract | ||
| Background: Patients with lymphedema are susceptible to a loss of balance. The Fullerton Advanced Balance Scale assesses the multiple dimensions of balance in these patients. The FABS was translated and validated in several languages, but there are no published reports in Arabic. Purpose: To find out the validity and reliability of the translated version of FABS among the Arab population in Egypt. Methods: The study was conducted in two main steps, as follows: Step 1: The FABS underwent translation from English to Arabic (examining both forward as well as backward translations). The final version underwent rigorous evaluation by experts to assess its face and content correctness, as well as its authentication. Step 2: The assessment of its psychometric properties was conducted on 107 females with lymphedema. Their ages were between 30 and 60 years old. Feasibility was assessed by measuring the time spent filling out the scale. Internal consistency and test-retest reliability were also used to assess the reliability. Patients were asked to complete the scale once every week on average, and they were also asked to re-fill it to ensure test-retest reliability. Results: FABS had excellent face validity, with a clarity scale score of 94% and a mean proportion of clear responses of 94%. Additionally, the mean proportion of relevant responses was found to be 98%. Furthermore, the scale demonstrated excellent content validity, reaching a value of 0.98. It exhibited a Cronbach's alpha coefficient of 0.81, suggesting a high degree of internal consistency and good test-retest reliability across all items. The ICC varied from 0.816 to 0.979. The overall score ICC was 0.977, with a 95% confidence interval spanning from 0.965 to 0.985. Conclusion: The FABS Arabic version is simple to use, reliable, and a valid tool for the identification of balance deficits among patients with lymphedema. | ||
