Cross-cultural adaptation of Turkish version of Parental-Caregiver Perceptions Questionnaire (P-CPQ)

Parental-Caregiver Perceptions Questionnaire (P-CPQ) is one of the scales used for evaluating the quality of life of children. Dental caries is an important factor affecting oral health-related quality of life. It was aimed to translate into Turkish and evaluate the psychometric properties of the P-CPQ with the evaluation of dental caries status of 6- to 14-year-old children.

Children-parent pairs attending to paediatric dental clinic were involved. After the translation and adaptation of the scale, the data were collected from the parents with the Turkish version of the P-CPQ and a short questionnaire, and then, the intra-oral examination of the children was performed by a paediatric dentist. Statistical analysis was performed by using SPSS version 22.0 and SPSS AMOS 22. The significance level was 0.05. Confirmatory factor analysis for construct validity; and item analysis, item discrimination index and the Cronbach alpha internal consistency coefficient for reliability measurement were calculated. Discriminant validity was tested by comparing the median P-CPQ scores between children with caries experience and those without.

Totally, 312 children-parent pair (52.9% female) participants were involved. The mean age of participated children was 9.00 ± 1.89. P-CPQ score was calculated by summing the scores of all 31 items; the mean score of the parents was 18.8 ± 12.8. Cronbach's alpha for the total scale was 0.87 and ranged from 0.680-0.795 for four subscales. The relationship between total and subscales was found to be statistically significant. Confirmatory factor analysis, item analysis and item discriminant index were approved. Model fit values were admissible.

Turkish version of P-CPQ was created, and it had good internal consistency reliability of subscales and found to be valid in 6- to 14-year-old children.
