Validation of the CPQ 8-10ESP in Mexican School children in urban areas

ABSTRACT

The current indicators used to gather information on oral health in children are basically clinical indexes thatregister mainly dental caries, periodontal disease, and malocclusion. These indexes should be complemented withemotional and social aspects related to the individual experience and perception of oral health status. In orderto obtain this information, valid instruments capable of evaluating the impact of oral health as it relates to thequality of life (OHRQoL) are required. The objective of the Child Perceptions Questionnaire (CPQ8-10) is to assessOHRQoL in children aged eight to ten years. CPQ8-10 consists of 25 questions divided into four domains oralsymptoms, functional limitation, emotional well-being, and social well-being.Objective: The aim of this study was to validate the translated Spanish version of the Child PerceptionsQuestionnaire (CPQ8-10ESP) in use with Mexican urban children.Material and Methods: Three hundred fifteen students in Mexico City aged eight- to ten-years-old participatedin this study. The CPQ8-10ESP questionnaire was self-administered in the classroom. Clinical data about caries andmalocclusion were obtained. To assess test-retest reliability, the questionnaire was reapplied to a subgroup ofchildren.Results: Cronbach’s alpha reliability coefficient was 0.89 for the total CPQ8-10ESP scale. The intraclass correlationcoefficient was 0.67; a statistically significant difference was found in the CPQ8-10ESP mean score between childrenwith caries and malocclusion; a significant correlation between general well-being ratings with all domainswas found (p<0.001). General perception of oral health was associated with both oral symptoms (p=0.049) andemotional well-being (p=0.022) domains, as well as with the total scale (p=0.015).Conclusions: The CPQ8-10ESP version showed good validity and reliability for use with Mexican schoolchildrenfrom urban areas (AU)
