Brazilian validation of the Parental-Caregiver Perceptions Questionnaire

Objectives: The Parental-Caregiver Perceptions Questionnaire (P-CPQ) is an instrument that assesses the parental knowledge of their children's Oral-Health-Related Quality of Life (OHRQoL). The aim of the study was to validate a Brazilian version of the P-CPQ. Methods: The translation and cross-cultural adaptation of P-CPQ was tested on 163 parents of 11-to-14-year-old children. Their children were clinically and radiographically examined for the presence or absence of dental caries and malocclusion and parents completed the P-CPQ with respect to their child's oral health. The children were receiving dental care at the Pediatric Dental and Orthodontics clinics of the Federal University of Minas Gerais, Brazil. Reliability of the instrument was determined through internal consistency and test-retest reliability. The internal consistency was assessed by Cronbach's Alpha Coefficient and the test-retest reliability by Intraclass Correlation Coefficient (ICC). The validity of the P-CPQ was determined through discriminant and convergent validity. Results: The mean P-CPQ score for the whole sample was 14.99 [standard deviation (SD) 13.45]. In the group with caries the mean score was 12.02 [SD 11.73] and in the group with malocclusion it was 17.72 [SD 14.45]. Significant associations were identified between caries status and malocclusion for the domain social well-being and for the overall score of P-CPQ (p<0.05). Internal reliability was confirmed by a Cronbachxs alpha coefficient of 0.85. Test-retest reliability revealed good reproducibility (ICC=0.89). Conclusion: The Brazilian version of P-CPQ exhibited good psychometric properties, being a valid instrument to be used with parents of Brazilian children from 11 to 14 years.
