Purpose

This study aimed to develop Turkish
measures for Pediatric Oral Health-related Quality of Life (POQL) and evaluate
their reliability and validity for use in Turkish children aged 8–14 years
(Child Self-Report measure; CSR) and their caregivers (Parent Report-on-Child
measure; PRC).

Materials and methods

The English POQL was translated into
Turkish, adapted for the Turkish culture, and tested in 149 children and their
caregivers attending the Çukurova University Pediatric Dentistry clinics to
assess the reliability, internal consistency, and discriminant and convergent
validity of the Turkish version.

Results

The internal consistency of the Turkish
POQL evaluated using Cronbach’s alpha was 0.905 for CSR and 0.887 for PRC. To
determine the test–retest reliability, the Turkish POQL was administered to a
sub-sample (n=16) a second time 2 weeks after the first survey administration.
Intraclass correlation coefficient values of the individual items were 0.895
for CSR and 0.992 for PRC. For total scores, there was a significant difference
based on clinical caries status and perceived oral health in both CSR and PRC.

Conclusion

The Turkish POQL is a valid and reliable
measure of the perceived impact of oral conditions on children’s lives.
