Validity and reliability of a questionnaire for measuring child oral-health-related quality of life.
Oral-health-related quality of life measures that exist are designed for adults. This study aimed to develop and evaluate the CPQ(11-14), a self-report measure of the impact of oral and oro-facial conditions on 11- to 14-year-old children. An item pool was generated with the use of a literature review and interviews with health professionals, parents, and child patients. The 36 items rated the most frequent and bothersome by 83 children were selected for the CPQ(11-14). Validity testing involved a new sample of 123 children. Test-retest reliability was assessed in a subgroup of these children (n = 65). Mean CPQ(11-14) scores were highest for oro-facial (31.4), lower for orthodontic (24.3), and lowest for pedodontic (23.3) patients. There were significant associations between the CPQ(11-14) score and global ratings of oral health (p < 0.05) and overall well-being (p < 0.01). The Cronbach's alpha and intraclass correlation coefficient for the CPQ(11-14) were 0.91 and 0.90, respectively. These results suggest that the CPQ(11-14) is valid and reliable.
