title: Reliability and validity of the French-Canadian version of the scoliosis research society 22 questionnaire in France.
abstract: METHODS
  Outcome study to determine the internal consistency, reproducibility, and concurrent validity of the French-Canadian version of the Scoliosis Research Society 22 (SRS-22 fcv) patient questionnaire in France.
  
  
  OBJECTIVE
  To determine whether the SRS-22 fcv can be used in a population from France.
  
  
  BACKGROUND
  The SRS-22 has been translated and validated in multiple countries, notably in the French-Canadian language in Quebec, Canada. Use of SRS-22 fcv seems appropriate for evaluating adolescent idiopathic scoliosis in France. However, French-Canadian French is noticeably different from the French spoken in France, and no study has investigated the use of a French-Canadian version of a health-quality questionnaire in another French population.
  
  
  METHODS
  The methods used for validating the SRS-22 fcv in Quebec were adopted for use with a group of 200 adolescents with idiopathic scoliosis and 60 healthy adolescents in France. Reliability and reproducibility were measured by the Cronbach α and intraclass correlation coefficient (ICC), construct validity by factorial analysis, concurrent validity by the Short-Form of the survey, and discriminant validity by analysis of variance and multivariate linear regression.
  
  
  RESULTS
  In France, the SRS-22 fcv showed good global internal consistency (Cronbach α = 0.87, intraclass correlation coefficient = 0.92), a coherent factorial structure, and high correlation coefficients between the SRS-22 fcv and Short-Form of the survey (P < 0.001). However, reliability and validity were slightly less than that for the instrument's original validation and the validation of the SRS-22 fcv in Quebec. These differences could be explained by language and cultural differences.
  
  
  CONCLUSIONS
  The SRS-22 fcv is relevant for use in France, but further development and validation of a specific French questionnaire remain necessary to improve the assessment of functional outcomes of adolescents with scoliosis in France.
