This dataset includes patient and clinical characteristics, and questionnaire responses of n=107 patients whom participated in the study: "A head-to-head comparison of the adult EQ-5D-5L and youth EQ-5D-Y-5L in adolescents with idiopathic scoliosis". Patients were treated with a brace for their scoliosis during this study.

Patient characteristics include self-reported characteristics including age, sex, education, BMI. Clinical characteristics include cobb angle at diagnosis, at initiation of bracing, at inclusion in this study, and Lenke classification. Questionnaires include a first measurement of the EQ-5D-5L, EQ-5D-Y-5L, the corresponding Visual Analogue Scales, the SRS-22r (scoliosis-specific questionnaire). A second measurement of these questionnaires was obtained at least 7-14 days after completions of the first; approximately 75% of patients responded to the second measurement.
