A Systematic Review of Self-Reported Outcome Measures Assessing Disability Following Hand and Upper Extremity Conditions in Persian Population

Background: Disability following hand and upper extremity conditions is common. Patient-reported outcome measures(PROs) are used to capture patients’ status subjectively. This review has aimed to synthesis the literature regarding theextent and methodological quality of translation, cross-cultural adaptation, and psychometric properties of the hand andupper extremity disability PROs in the Persian language.Methods: Seven electronic databases (MEDLINE, EMBASE, Psychinfo, Scopus, ISI, Science direct, and GoogleScholar) were searched until May ۲۰۲۰. Studies reporting cross-cultural adaptation and psychometric properties testingof the Persian validated disability PROs of the hand and upper extremity were identified. We appraised the eligiblestudies using Guidelines for the Process of Cross-cultural Adaptation of Self-report Measures and COnsensus-basedStandards for the selection of health Measurement INstruments (COSMIN) risk of bias checklist.Results: Out of ۹۸ identified records, ۲۲ studies on ۱۷ PROs were reviewed. Most of the PROs (۴۷%) were regionspecificand the others were condition-specific (۲۹%) and multi-region (۲۴%). Most of the studies (۶۷%) followed ۸۰to ۱۰۰% of the recommended steps for cross-cultural adaptation and translation of a PRO. The evidence of internalconsistency, test-retest reliability, and construct validity was available for all the PROs. Structural validity, measurementerror, and responsiveness were evaluated for five, six, and four PROs, respectively. The overall risk of bias ranged from“inadequate” to “very good” for all studies.Conclusion: A reasonable number of PROs for the evaluation of hand and upper extremity disability are available inthe Persian language. Although all of them are not of very good psychometric properties, they all have sufficient qualityto be used in clinical settings.Level of evidence: II
