Abstract
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. 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). 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 < 0.001). Higher CPQ scores were found for children with self-perceived poor general health (p < 0.001) or oral health (p < 0.001), unsatisfactory oral health (p < 0.001), need for dental treatment (p < 0.001) and perception of dental aesthetic problems (p < 0.001). Multiple linear regression models showed that the recruitment setting, the DMFT index and the DAI index were significantly associated with the CPQ global score (p = 0.004). The Lebanese version of the CPQ11–14 showed excellent psychometric properties and was able to distinguish children with different oral conditions. Additional longitudinal studies should be performed to test the properties of this questionnaire in clinical samples.

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
Clinical variables were found to be of limited use for determining therapeutic needs and the concept of oral health related quality of life (OHRQoL) has been developed to quantify the extent to which oral health problems interfere with a patient’s daily life and well-being [8]
The CPQ was developed in Toronto to measure OHRQoL for children [9]
Summary
The aim of this study was to assess the reliability, reproducibility, and convergent and discriminant validity of the Child Perceptions Questionnaire (CPQ) in a group of 11–14-year-old Lebanese children. Adolescence is a critical period of life, associated with the specific social and psychological needs of children [1]. Oral health disorders such as malocclusion, caries and periodontal disease affect adolescents’ quality of life [2]. The CPQ was later evaluated in many English-speaking countries and translated and validated in different cultural and linguistic situations [12,13,14,15,16]. It was translated into Arabic and validated in populations in Egypt, Syria and Saudi Arabia [17, 18]. Once the translated questionnaire has been adapted, its equivalence should be determined by testing its psychometric properties
