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 (ρ = 0.37) and overall well-being (ρ = 0.40). The Arabic version of the short form CPQ 11–14 was reliable and valid for this general population of children.
