Agreement between adolescents and parents/caregivers in rating the impact of malocclusion on adolescents' quality of life

Abstract

To assess the agreement between adolescents and their parents/caregivers regarding the impact of malocclusion on adolescents' oral health-related quality of life (OHRQoL). A consecutive sample of 141 adolescent and parent/caregiver pairs was selected. Adolescents answered the short version of the Child Perceptions Questionnaire (CPQ11-14), while parents answered the Parental-Caregiver Perceptions Questionnaire (P-CPQ). The CPQ11-14 and the P-CPQ have 14 items in common that are organized through four subscales: oral symptoms (OS), functional limitations (FL), emotional well-being (EW), and social well-being (SW). Agreement on the overall score and agreement on the subscales were determined using comparison and correlation analysis. The comparison analysis was carried out by comparing the mean directional and absolute differences, and the correlation analysis was performed using the intraclass correlation coefficient (ICC). A total of 135 pairs of adolescents and parents/caregivers agreed to answer the questionnaires, providing a response rate of 95.7%. The mean age of the adolescents was 11.50 years. The mean directional difference was significant for the OS (P < .001) and FL (P = .040) subscales as well as for the overall score (P = .007). Adolescents' reports were higher than parents/caregivers' reports. The mean absolute difference for the overall score was 7.26, representing 12.9% of the maximum possible overall score. The ICC was 0.16 for the overall score, indicating poor agreement. Poor agreement was observed between adolescents and their parents/caregivers in rating the impact of malocclusion on adolescents' OHRQoL.
