Cross-Cultural Validation of Urdu Version KOOS in Indian Population with Primary Knee Osteoarthritis

Abstract

Purpose The primary aim of this study was to translate a self-reported questionnaire (KOOS) from English to Urdu and then to see its internal consistency, agreement, test-retest reliability, and validity among primary OA knee patients. Methodology First, KOOS questionnaire was translated from English language to Urdu through standardized cross-cultural protocol. This translated version of KOOS was administered to 111 radiographically diagnosed primary OA knee patients at two times with 48-hour interval in-between. Cronbach's alpha, floor and ceiling effect, intraclass correlation coefficient (ICC), absolute agreement %, and Spearman correlation were used to fulfill our objectives. Results Average time to administer this questionnaire was 20 minutes. There was good internal consistency with Cronbach's alpha ranging from 0.7246 to 0.9139. The absolute agreement of each item between two tests ranged from 81.08% to 98.20%. Test-retest reliability was excellent (“r” ranged from 0.9673 to 0.9782). There was no ceiling effect; however less than 4% floor effect was seen in two subscales. There was significant difference that existed between different X-ray grades in all subscales meaning good content validity for disease prognosis. Conclusion The present results show that KOOS Urdu version is a reliable and valid measure for primary OA knee patients.

Patient-Rated Outcome Measure Using Disease-specific Koos-PS Short Form Arabic Questionnaire in Knee Osteoarthritis

“…Few studies have stated that the cultural activities such as squatting and kneeling along with a maximum knee flexion range of motion are common in the Middle East, [27,28] linked to knee OA and such cultural activities lead to the development of knee osteoarthritis [29]. Our sports/rec domain values with an older age group are nearly similar to the values produced in a KOOS cross-cultural study conducted recently by Ateef M et al (2017) in India [30]. One Japanese study by Zhang Y.…”

“…The developer of the KOOS-Short Form (12 items) have recently stated that different short forms with diverse content provide domain specific joint impact scores ( Gandek et al, 2019a ; Gandek et al, 2019b ) which supports the concept of Arabic KOOS-PF cultural adaptation and validation. One KOOS-Urdu validation study ( Ateef, Kulandaivelan & Alqahtani, 2017 ) also supports this Arabic KOOS-PF stiffness (PF1) Cronbach’s alpha (0.81) where it was marginally higher than their symptom Cronbach’s alpha 0.788. The other two item domains (pain, 0.87 and QOL, 0.72) are supporting the results keeping the values within the standard psychometric values ( Terwee et al, 2007 ).…”

“…The Intraclass correlation coefficient (ICC) of KOOS-PF was 0.959 and higher to the symptom domain 0.94 (corresponding to Arabic KOOS-PF1), pain domain 0.93 (corresponding to Arabic KOOS-PF2-10) and QOL domain 0.93 (corresponding to Arabic KOOS-PF11) of long-form of KOOS Arabic version ( Alfadhel et al, 2018 ). The Intraclass correlation coefficient (ICC) of KOOS-PF was 0.959 and similar to the symptom domain 0.96 (corresponding to Arabic KOOS-PF1), lower to pain domain 0.978 (corresponding to Arabic KOOS-PF2-10) and similar to QOL domain 0.968 (corresponding to Arabic KOOS-PF11) in long-form of KOOS Urdu version of India ( Ateef, Kulandaivelan & Alqahtani, 2017 ).…”

“…More than 65 million people worldwide speak Urdu, mostly from Pakistan and India. Moreover, Urdu is the national language of Pakistan [ 27 , 28 ]. In Pakistan, people do not read or understand English very well, so different questionnaires should be translated into Urdu.…”
