Développement et validation de la version canadienne-française de l’échelle de Satisfaction des Adolescents de la gestion de la Douleur postopératoire – Scoliose idiopathique (SAD-S)

Background: Spinal fusion for scoliosis generates moderate to severe pain intensity. There are currently no instruments available to measure adolescents’ satisfaction regarding post-spinal fusion pain management. Aims: To develop and validate a scale on satisfaction of adolescents regarding pain management following spinal fusion for scoliosis. Methods: A methodological design was used to develop and validate the French-Canadian scale “Satisfaction des Adolescents de la gestion de la Douleur postopératoire – Scoliose idiopathique (SAD-S)”. A modified Delphi method, with seven healthcare professionals and 10 adolescents, was used to establish content validity of the SAD-S. A pre-test of the scale was conducted with 10 adolescents post-spinal fusion. The final version of the scale was validated through a pilot study with 98 adolescents following their surgery. Results: The SAD-S scale includes a total of 13 items. Principal component analysis yielded a two-factor structure (2 subscales): 1) Pain management education and 2) Education regarding medication. These two factors explained 47,8% of the total variance for satisfaction. A Cronbach’s alpha of 0,84 was obtained for internal consistency. Conclusion: Validation of the SAD-S scale showed that it has good psychometric properties with this population. Further validation is required with a larger sample to pursue its validation.
