Population-based normative data for the Scoliosis Research Society 22r questionnaire in adolescents and adults, including a comparison with EQ-5D.
The Scoliosis Research Society (SRS) 22r questionnaire is a widely used instrument. To estimate the disorder´s impact on quality of life and to gain knowledge about treatment effects, normative values are needed.



Individuals were randomly invited from the general population. 272 individuals (145 females) answered the SRS-22r and EuroQol 5-dimensions (EQ-5D) questionnaires and stratified according to sex and age; ≤19 years (n = 61), 20-39 years (n = 66), 40-59 years (n = 84) and ≥60 years (n = 61). The correlation between SRS-22r and EQ-5D were analyzed.



There were modest variations in mean SRS-22r scores (ranging between 4.3 and 4.7). EQ-5D followed the same pattern. The correlation between the SRS-22r was 0.62 (p = 0.001) and 0.61 (p < 0.001) for the EQ-5D UK tariff and EQ-5D Swedish tariff, respectively.



We provide the first SRS-22r normative data for adolescents and adults overall. We found a good correlation between SRS-22r and EQ-5D in individuals without spinal deformity.
