TI  - Discrimination validity of the scoliosis research society-22 patient 
      questionnaire: relationship to idiopathic scoliosis curve pattern and curve size.
PG  - 74-8
AB  - STUDY DESIGN: Prospective observational study. OBJECTIVE: To determine the 
      discriminant validity of the Scoliosis Research Society-22 (SRS-22) 
      health-related quality-of-life (HRQL) questionnaire for idiopathic scoliosis 
      patients based on curve pattern and curve size. SUMMARY OF BACKGROUND DATA: An 
      important psychometric attribute of the HRQL questionnaire is the capacity to 
      discriminate between and among patients with differing condition severity. 
      METHOD: Three study groups, with subjects ranging in age from 10 to 16 years, 
      were set up: a control group (C) of 19 persons with scoliosis suspected but 
      unproven with an average age of 13 years; a nonsurgical group (NS) of 68 patients 
      with an average age of 14 years and an average scoliosis (Cobb) of 30 degrees; 
      and a presurgical group (PS) of 32 patients with an average age of 14 years and 
      an average scoliosis of 61 degrees. The NS group was subdivided into untreated 
      (NSU) (n = 54) and braced (NSB) patients (n = 14). Also created were subgroups of 
      the NS and PS groups having similar curve sizes: nonsurgical similar (NSS) and 
      presurgery similar (PSS). Statistical significance of the SRS-22 domain scores by 
      comparison groups was tested by ANOVA. Relationships between the SRS-22 
      questionnaire and scoliosis deformity measurements were calculated using the 
      Pearson Correlation Coefficients. RESULTS: There were no significant differences 
      between the control (C) and nonsurgical (NS) groups. The presurgical group (PS) 
      scored significantly lower in the pain and self-image domains than the C or NS 
      groups and lower than group C in the mental health domain. A subgroup of the 
      nonsurgical group (NSS) with curves comparable to the presurgical subgroup (PSS) 
      had significantly better self-image scores. There were no significant 
      correlations between SRS-22 scores and curve pattern. For persons with scoliosis, 
      curve size (Cobb) correlated with pain, self-image, and function; trunk asymmetry 
      correlated with self-image. CONCLUSION: The SRS-22 HRQL questionnaire 
      successfully discriminated among persons with no scoliosis or moderate scoliosis 
      and large scoliosis. It did not discriminate among patients with single, double, 
      or triple curves. Self-image and, to a lesser extent, pain and function domain 
      scores correlated with radiographic and trunk asymmetry severity. The SRS-22 HRQL 
      questionnaire may be useful in choosing nonsurgical versus surgical treatment in 
      borderline cases.
