Brief summary

This observational study aims to validate the French version of the Smile Esthetics-Related Quality of Life (SERQoL) questionnaire in adult patients recruited in two APH-HP dental departments. The study evaluates internal consistency, test-retest reliability, and construct validity of the questionnary. A total of 120 patients will be recruited from dental departments at two AP-HP hospitals.

Detailed description

This psychometric validation study involves adult patients receiving their first consultation at AP-HP dental services. The SERQoL questionnaire will be completed twice (at baseline and after 15 days). Internal consistency (Cronbach's alpha), test-retest reliability (intraclass or Pearson correlation), and factor structure (confirmatory factor analysis) will be analyzed. No clinical intervention is involved, and participation will not alter standard care.
