Reliability and validity of an adapted Arabic version of Scoliosis Japanese Questionnaire-27 in Saudi Arabia

Background: The Scoliosis Research Society SRS-22 questionnaire is a standard tool to assess the Health- Related Quality of Life (HRQoL) in scoliosis patients but, because of cultural differences limited use among Arabic patients. The aim is to perform a cross-cultural adaptation and validation of Arabic version of Scoliosis Japanese Questionnaire-27 and test it on Saudi patients with adolescent idiopathic scoliosis (AIS). Methods: This a cross sectional study run between July 2021 and December 2022 recruited 194 patients. The cross-cultural adaptation process was performed using the American Association of Orthopedic Surgeons (AAOS) Outcomes Committee method. All patients had completed the Arabic version of Scoliosis Japanese Questionnaire-27 and SF-12 preoperatively and 3-month postoperatively. The validity and internal consistency were tested using the Intraclass correlation coefficient (ICC), Cronbach alpha, Pearson correlation coefficient, and confidence interval (CI). Results: We analyzed the result of 194 female adolescent patients. The average age is 14 +/- 2.4 years (range from 10 to 21 years). The majority of patients have a Lenke type 1 curve (54 %). The overall Cronbach alpha (CA) of all domains of Scoliosis Japanese Questionnaire-27 is 0.92. However, the Cronbach alpha for the mental health (Q17,18,20,21,23,24) and, self-image (Q12-14,22,25,26) are 0.93 and 0.84 respectively. Conclusion: The Arabic version of Scoliosis Japanese Questionnaire-27 is a reliable and valid instrument and can be applied to evaluate the quality of life in patients with AIS.
