Comparison of Korean Body Image Questionnaires in Adolescent Idiopathic Scoliosis

Study Design: A prospective study. Purpose: To obtain the results of four body image questionnaires analyzed for validity in Korean and compare them to radiographic findings and quality of life scores. Overview of Literature: Each of the four body image questionnaires has been studied, but comparative studies of each other are rare. Methods: Adolescent idiopathic scoliosis (AIS) patients ages 10 to 19 years completed the Korean version of the Quality of Life Profile for Spinal Deformities (K-QLPSD), the Scoliosis Research Society-22 self-image subscale (K-SRS-22-si), Korean version of the Spinal Appearance Questionnaire (K-SAQ), Korean version of the Body Image Disturbance Questionnaire-Scoliosis (K-BIDQ-S), and Korean version of the Italian Spine Youth Quality of Life (K-ISYQOL). Four body image questionnaires were compared with K-ISYQOL and radiographic major curve magnitude, coronal balance, and sagittal balance. Spearman's correlation was performed to compare the four body image questionnaires. Results: The study included 84 AIS patients, with a mean age of 12.6 years and a major Cobb angle of 29.4 degrees. The four surveys were correlated with major curve magnitude and K-ISYQOL. K-SAQ and K-BIDQ-S were correlated better than K-QLPSD, and K-SRS-22-si was correlated with K-ISYQOL. The four surveys were moderately correlated with major curve magnitude, but there was no correlation with age, coronal balance, and sagittal balance. Conclusions: K-SAQ and K-BIDQ-S correlate better with K-ISYQOL than K-QLPSD and K-SRS-22-si.
