Parental-caregiver perceptions of child oral health-related quality of life (P-CPQ): Psychometric properties for the peruvian spanish language

摘要

Objectives: The aim of the study was to cross-culturally adapt the Parental-Caregiver Perceptions Questionnaire (P-CPQ) to the Peruvian Spanish language and assess its reliability and validity. Study Design: To translate and cross-cultural adapt the instrument, 60 parents answered the P-CPQ in two pilot tests. The final version of the P-CPQ was evaluated in 200 parents of children aged 11 to 14 years, who were clinically examined for dental caries. The internal consistency was assessed by Cronbach’s alpha coefficient while repeat administration of the P-CPQ on the same 200 children facilitated the test-retest reliability via intraclass correlation coefficient (ICC). Construct and discriminant validity were based on associations of the P-CPQ with global ratings of oral health and clinical groups, respectively. Results: The mean (standard deviation) P-CPQ score was 15.64 (11.89). Internal consistency was confirmed by a Cronbach’s alpha of 0.84. Test-retest reliability revealed excellent reproducibility (ICC= 0.94). Construct validity was satisfactory, demonstrating significant correlations between global ratings (oral health and overall well-being) and the total scale and for subscale. Discriminant validity was significant (p<0.001), supporting its ability to discriminate between clinical groups. Conclusions: The Peruvian Spanish P-CPQ has satisfactory psychometric properties to assess parental-caregivers perceptions on their children’s oral health-related quality of life. > Key words:Quality of life, oral health, children, validity, reliability.
