title: Agreement between adolescents and parents or caregivers in rating adolescents' quality of life during orthodontic treatment.
abstract: BACKGROUND
  The purpose of this study was to assess the agreement between Brazilian adolescents and their parents or caregivers regarding the adolescents' oral health-related quality of life during orthodontic treatment.
  
  
  METHODS
  The sample consisted of 102 adolescent-parent/caregiver pairs. Adolescents answered the short form of the child perceptions questionnaire, and the parents or caregivers answered the parental-caregiver perceptions questionnaire. These questionnaires have 14 items in common organized across 4 subscales: oral symptoms, functional limitations, emotional well-being, and social well-being. Agreement on the overall score and the subscales was determined using comparison and correlation analysis. The former was performed through comparison of the mean directional and absolute differences. The latter was analyzed using the intraclass correlation coefficient.
  
  
  RESULTS
  The mean directional difference was significant for the oral symptoms subscale, with parents' reports lower than adolescents' reports (P = 0.012). However, it was not significant for the other 3 subscales and the overall score (P >0.05). The mean absolute difference for the overall score was 5.15, representing 9.2% of the maximum possible score. The intraclass correlation coefficient was 0.66, indicating substantial agreement.
  
  
  CONCLUSIONS
  There was agreement between adolescents and their parents or caregivers in rating adolescents' oral health-related quality of life during orthodontic treatment.
