Evaluation of a quality of life measure for children with malocclusion

Abstract

Objective: To explore the validity and reliability of the Child Perception Questionnaire as an oral health-related quality of life (OHRQoL) measure in adolescents with malocclusion.

Agreement between mothers and children with malocclusion in rating children's oral health-related quality of life

“…Table IV Standardized and absolute differences between the total and four sub-domain scores from the paired child CPQ [11][12][13][14] and maternal P-CPQ data. Table V Comparison of the mean scores from the global, life overall and satisfaction with teeth questions.…”

“…The child and whichever parent was present at the consultation were asked to independently complete the Child Perception Questionnaire for children aged 11-14 years (CPQ [11][12][13][14] ) and the Parental-Caregiver Perceptions Questionnaire (P-CPQ) respectively. The child and parent completed the questionnaires separately in a quiet area of the orthodontic clinic with a researcher available to answer any questions.…”

“…Comparisons between the mean total and four domain scores from the CPQ [11][12][13][14] and P-CPQ responses are shown in Table II. The mean ratings were similar for the total score (20.4 child v 20.1 mother), oral symptoms (5.2 child v 4.7 mother) and social well-being (4.3 child v 4.8 mother) domains.…”

“…The CPQ [11][12][13][14] and P-CPQ are comparable questionnaires with 31 items in common organised into four domains, namely oral symptoms, functional limitations, emotional and social well-being. In a study of 42 mothers and children, Jokovic et al 12 found generally good agreement within the groups.…”

“…Patients with active dental disease, cleft lip and/or palate, a complicating medical history, or severe dental mottling were excluded. A sample size calculation suggested that ninety patients would need to be recruited to detect a difference of thirty percent in the total CPQ (α = 0.05; β = 0.90) between individuals with and without malocclusion 14 .…”
