Cross Validity of the Korean Version of SRS-22 in Korean Pa-tients with Idiopathic Scoliosis

In 1999, the Scoliosis Research Society first de-veloped the Scoliosis Research Society Outcome Questionnaire (SRS-22), an instrument used to measure the health-related quality of life of pa-tients with scoliosis (1). Since then, the revised questionnaire has been translated not only into English but also into various languages and is being widely used (1-3). The SRS-22 consists of five domains covering function (5 questions), pain (5 questions), self-image (5 questions), men-tal health (5 questions), and satisfaction (2 ques-tions) with treatment.
