Abstract Background The aim of this study was to assess the reliability, reproducibility, and convergent and discriminant validity of the Child Perceptions Questionnaire (CPQ)11–14 in a group of 11–14-year-old Lebanese children. Methods This was a cross-sectional study. Children aged between 11 and 14 were recruited between March and June 2014 from five schools in Beirut and the surrounding region: a central public school and four private schools. Data were collected from self-administered questionnaires and a clinical intraoral examination was conducted. In addition to the CPQ11–14, the questionnaires included socio-demographic characteristics, questions about each child’s perception of oral and general health status and dental aesthetics, satisfaction with dental conditions and the need for dental treatment. The oral examination included the number of teeth affected by caries (D3 level), fillings, the number of missing teeth and an orthodontic assessment of malocclusion using the Dental Aesthetic Index (DAI). Results The final number of children included was 693 and their mean age was 13.14 ± 0.82 years; 54.4% were boys. The mean CPQ score was 15.60 ± 14.55, range 0 to 110. Cronbach’s alpha of the global CPQ score was 0.880 and varied from 0.897 to 0.908. The reproducibility of the overall CPQ score was good, as was the CPQ score for each of the four domain scores (ICC > 0.682; p
