Cross-sectional mail questionnaire.Assess the feasibility of translating total and domain scores from Scoliosis Research Society (SRS)-24, SRS-23, SRS-22 to SRS-22r.Three successive editions original SRS-24 health-related quality-of-life questionnaire have resulted efforts improve its psychometric properties validate use in patients down 10 years age. This need establish, if possible, conversion equations last most thoroughly validated version, SRS-22r.A consolidated 49 questions that incorporated various four questionnaires was mailed a consecutive series 235 who had received primary posterior or anterior instrumentation arthrodesis treat adolescent idiopathic scoliosis. Regression modeling used establish SRS-24, SRS-22r.One hundred twenty-one (51%), aged 23.3 ± 4.52 (range 14.2-34.6 years), returned at 8.6 4.00 2.3-15.9 years) following surgery. Estimation SRS-22r nonmanagement domains mean SRS-23 is excellent (R2 0.97-0.99) good for 0.80-0.82, improving 0.86 0.87 after minimal reconfiguration). individual 0.81-0.99). Minimal reconfiguration improves pain R2 = 0.71 0.76, which are both fair; function 0.69 0.74 0.83, poor fair good; satisfaction/dissatisfaction with management 0.64 0.80, good. Conversion self-image 0.60) despite correlation being statistically significant.With one exception, questionnaire, domains, can be translated accuracy, further improved some instances by reconfigurations. The sole exception self-image, translates poorly.
