Abstract

Background context The Scoliosis Research Society 22 Questionnaire (SRS-22) has shown to worsen with increasing deformity in adolescents with idiopathic scoliosis (AIS). However, all the studies have been performed on patients who have already been diagnosed and in relatively small samples. Purpose The purposes of this study were to evaluate a large sample of consecutive patients before diagnosis to develop reference values and check the discriminative validity and correlation with deformity of the SRS-22. Study design/setting This is a cross-sectional study, with patients referred to a specialized outpatient scoliosis rehabilitation institute. Patient sample The recruited subjects were 1,205 consecutive adolescents, 75% females (13.7±1.9 years), before their first scoliosis evaluation. Five subgroups were 0°-10° Cobb (normal) and 11° to 20°, 21° to 30°, 31° to 40°, and greater than 40° (AIS). Outcome measures The outcome measure is based on the SRS-22. Methods The SRS-22 was used to examine the differences between the domains of the five subgroups and total scores, and it was correlated with Cobb degrees and curve location. We used one-way analysis of variance and Spearman rho test. Results Apart from the self-image domain in both genders and all subgroups, all other scores were greater than 4 points with small standard deviations. Females showed significant differences among groups for all domains and total score (p.1). All differences found were less than the minimally clinically significant change (0.5 points). The correlations with the severity of deformity measures were very low (rs
