Validity and reliability of the Arabic short version of the child oral health-related quality of life questionnaire [CPQ 11–14] in Medina, Saudi Arabia

The Arabic version of the Child Perception Questionnaire for assessing oral health-related quality of life in 11–14 year olds [CPQ 11–14] has been previously validated. This study tested the validity and reliability of the short version of the Arabic CPQ 11–14 in the general population of Medina, Saudi Arabia. A total of 268 schoolchildren completed the questionnaire and were examined to determine the prevalence of caries and malocclusion. The mean total score was 8.53 [SD 8.18], and 7% of children scored zero. There was a significant association between malocclusion and oral symptoms and between DMFT score and functional limitations. The test–retest reliability [0.78] and Cronbach alpha [0.82] were excellent. The construct validity was acceptable for oral health [P = 0.37] and overall well-being [P = 0.40]. The Arabic version of the short form CPQ 11–14 was reliable and valid for this general population of children
