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 validated previously. This study tested the validity and reliability of a 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 (rho = 0.37) and overall well-being (rho = 0.40). The Arabic version of the short form CPQ 11-14 was reliable and valid for this general population of children.
