Abstract

Purpose

To perform a cross-cultural adaptation and validation of Saudi Arabic (SA) version of SRS-30 and test it on Saudi patients with adolescent idiopathic scoliosis (AIS).

Methods

A retrospective analysis of prospective collected data of 322 patients with AIS. The cross-cultural adaptation process was performed using the American Association of Orthopedic Surgeons (AAOS) Outcomes Committee method. A pre-test analysis was conducted on 30 patients. All patients had completed the SRS-22r and SF-12 preoperatively and 198 patients had completed the SA version of SRS-30 and SF-12 postoperatively twice at six weeks interval. The validity and internal consistency were tested using the interclass correlation coefficient (ICC), Cronbach alpha, person correlation coefficient, and confidence interval (CI).

Results

There are 288 (89.4%) girls and 34 (10.6%) boys and the average age is 15 ± 2.3 years (range from 10–21 years). The majority of patients have a Lenke type 1 curve (41%) and only 14% have a Lenke type 5 and 6. The overall Cronbach alpha (CA) of all SRS-30 domains is 0.87. However, the Cronbach alpha for the satisfaction, and function domains slightly lower than the original English questionnaire.

Conclusion

The Saudi Arabic version of SRS-30 is a reliable and valid instrument and can be applied to evaluate the quality of life in patients with AIS.
