Translation, cross-cultural adaptation and validation of the Persian version of COOP/WONCA charts in Persian-speaking Iranians with multiple sclerosis

AbstractPurpose: Translation, cross-culturally adaptation and validation of a Persian version of COOP/WONCA charts in Persian-speaking Iranians with multiple sclerosis (MS).Method: The Persian version of COOP/WONCA charts was developed after a standard forward translation, synthesis and backward translation. A total of 197 subjects with MS participated in this study. They were asked to complete the COOP/WONCA charts and Short-Form 36 Health Survey (SF-36). The COOP/WONCA charts were re-administered to 50 patients, 4 weeks after the first session. Expanded Disability Status Scale (EDSS) was also scored for each subject by the referring physician. Construct validity was assessed by testing linear relationship between corresponding domains of the COOP/WONCA charts, the SF-36 and the EDSS. Test–retest reliability was examined using interclass correlation coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) values.Results: Related domains of COOP/WONCA charts and SF-36 dem...
