    Abstract:
    OBJECTIVES: The aim of this study was to develop and evaluate the P-CPQ, a measure of parental/caregiver perceptions of the oral health-related quality of life of children. This forms one component of the Child Oral Health Quality of Life Questionnaire (COHQOL). METHODS: An item pool was developed through a review of existing child health questionnaires and interviews with parents/caregivers of children with pedodontic, orthodontic, and orofacial conditions. The resulting 47 items were used in a study in which 208 parents/caregivers provided data on their frequency and importance. The 31 items rated the most frequent and important were selected for the final questionnaire (P-CPQ). The P-CPQ validity and reliability were assessed by a new sample of 231 parents, 79 of whom completed two copies for the assessment of test-retest reliability. RESULTS: The P-CPQ discriminated among the three clinical groups included in the expected direction. Within-group analyses using clinical data provided some evidence that scores were associated with the severity of the condition. The P-CPQ also showed good construct validity. It had excellent internal consistency reliability with a Cronbach's alpha of 0.94 and demonstrated perfect test-retest reliability (ICC=0.85). CONCLUSION: The study provides data to indicate that the P-CPQ is valid and reliable.
