摘要

Background: Patient Determined Disease Steps (PDDS) scale is a patient-reported outcome measure to assess disability in persons with multiple sclerosis (pwMS). This scale can be used as an alternative to Expanded Disability Status Scale (EDSS) as it is a costly, more time-consuming, and clinician-based method. This study aimed to conduct Turkish translation and cross-cultural adaptation of PDDS and investigate its psychometric properties. Methods: Turkish translation and cross-cultural adaptation of PDDS was conducted. Its psychometric properties including validity (i.e. content, criterion, and construct) and test-retest reliability (relative and absolute) were investigated in 100 pwMS. Results: PDDS had a significant strong correlation with EDSS (r(s) = 0.61, p .05). Relative test-retest reliability was found high [ICC = 0.99 (95%CI = 0.99, 0.99)]. Absolute test-retest reliability was high as the Bland-Altman analyses showed no significant systematic bias between the repeated assessments. A narrow range of the limits of agreement indicated that PDDS had high stability and low variation between first and second assessments. Conclusion: Turkish version of PDDS presented high validity and test-retest reliability in pwMS.
