Validation of the French version of the Child Perceptions Questionnaire for children aged 11 to 14 years old (CPQ11-14) short-form

Abstract Background The COHQoL is a set of questionnaires used to evaluate the impact of oral health on children’s quality of life. Although the CPQ8-10 and the P-CPQ have been translated and validated in French, the CPQ11-14 14 has not yet been validated. Aim The aim was to develop a French version of the CPQ11-14 16-items. Design: The French version of CPQ11-14 was obtained by a forward-backward translation process and pretested. The final version was tested on children aged 11–14 and divided into three groups: children with orofacial clefts, children with rare dental diseases other than clefts, and children without anomalies. We evaluated the reliability with test-retest and internal consistency, and the questionnaire validity with construct validity and discriminant validity. We performed an Exploratory Factory Analysis (EFA). Results 187 children tested the questionnaire. The ICC of the test-retest was 0.76 and the Cronbach’s alpha was 0.77. The correlation between the CPQ11-14 and self-assessment of oral health and general well-being was > 0.2. Patients with orofacial clefts and rare diseases had significantly higher scores for overall short-form CPQ11-14. The EFA revealed six factors. Conclusion The French CPQ11-14 is valid to assess the impact of oral health on children’s quality of life.
