Cross-cultural adaptation of the Child Perceptions Questionnaire 11–14 (CPQ11–14) for the Brazilian Portuguese language

Abstract

BackgroundOral-Health-Related Quality of Life (OHRQoL) instruments are being used with increasing frequency in oral health surveys. However, these instruments are not available in all countries or all languages. The availability of cross-culturally valid, multi-lingual versions of instruments is important for epidemiological research. The Child Perceptions Questionnaire 11–14 (CPQ11–14) is an OHRQoL instrument that assesses the impact of oral conditions on the quality of life of children and adolescents. The objective of the current study was to carry out the cross-cultural adaptation of CPQ11–14 for the Brazilian Portuguese language.MethodsAfter translation and cross-cultural adaptation, the CPQ 11–14 was tested on 160 11-to-14-year-old children who were clinically and radiographically examined for the presence or absence of dental caries. The children were receiving dental care at the Pediatric Dental and Orthodontic clinics of the Federal University of Minas Gerais, Brazil. To test the quality of the translation, 17 children answered the questionnaire. The internal consistency of the instrument was assessed by Cronbach's Alpha Coefficient and the test-retest reliability by Intraclass Correlation Coefficient (ICC).ResultsThe mean CPQ11–14 score were 24.5 [standard deviation (SD) 18.27] in the group with caries and 12.89 [SD 10.95] in the group without caries. Median scores were 20 and 10 in the groups with and without caries, respectively (p < 0.001). Significant associations were identified between caries status and all CPQ domains (p < 0.05). Internal reliability was confirmed by a Cronbach's alpha coefficient of 0.86. Test-retest reliability revealed satisfactory reproducibility (ICC = 0.85). The questionnaire proved to be a valid instrument. Construct validity was satisfactory, demonstrating highly significant correlations with global indicators for the total scale and subscales. The CPQ11–14 score was able to discriminate between different oral conditions (groups without and with untreated caries).ConclusionThe present study demonstrated that the CPQ11–14 is applicable to children in Brazil. It has satisfactory psychometric properties, but further research is required to evaluate these properties in a population study.

Impact of dental fluorosis on the quality of life of children and adolescents

“…There was an effect of fluorosis on the functional domain in both groups, as measured by the CPQ [8][9][10] and CPQ [11][12][13][14] . This domain examines issues mainly relating to chewing, which is the process of breaking and crushing of food using the posterior teeth (premolars and molars).…”

“…Th e total score ranged from 0 to 100 for the CPQ [8][9][10] and from 0 and 148 for the CPQ [11][12][13][14] . Higher scores denote a greater impact of oral health on quality of life.…”

“…OHRQOL was assessed using the Brazilian versions of the Child Perception Questionnaire (CPQ [8][9][10] ), which was validated by Barbosa et al 9 , and the adolescent CPQ (CPQ [11][12][13][14], which was validated by Gourgand et al 10 Th ese instruments were used to assess the impact of oral health on the quality of life of four groups of subjects: 8-10-year-old children with and without fl uorosis, and 11-12-year-old adolescents with and without fl uorosis.…”

“…The indices of fluorosis were dichotomized as either the presence of fluorosis (TFI scores 1-9) or no fluorosis (TFI score 0) and associated with sociodemographic variables by performing the chi-square test and Fisher's exact test. The overall mean and domain scores of the CPQ [8][9][10] and CPQ [11][12][13][14] were compared between the groups with and without fluorosis using the Mann-Whitney test.…”

Self-perception of oral health among schoolchildren in a city of Amazonas, Brazil: related factors

“…In order to verify the children's self-perception of oral health, the validated Brazilian version 8 of the CPQ8-10 Child Perceptions Questionnaire 5 was used, for children from 8 to 10-years-old, with 29 questions divided into four domains (oral symptoms, functional limitation, emotional well-being and social well-being) and the validated Brazilian version 9 of the CPQ11-14 Child Perceptions Questionnaire 5 for 11 to 14-year-olds, with 41 questions divided into the aforementioned four domains. The questionnaires were individually applied by a trained assistant in a reserved classroom.…”
