The German version of Child Perceptions Questionnaire for children aged 8 to 10 years (CPQ-G8–10): translation, reliability, and validity

Abstract

Objectives The aims of this study were to develop a German version of the Child Perceptions Questionnaire for children aged 8 to 10 years (CPQ-G8-10), a measure of oral health-related quality of life, and to assess the instrument's reliability and validity. Methods The original English version of the CPQ8-10 questionnaire was translated into German (CPQ-G8-10) by a forwardbackward translation method. A total of 409 8-to 10-year-old children who were recruited at the Department of Paediatric Dentistry in Vienna, Austria, participated in this study. The children self-completed the CPQ-G8-10 and were clinically examined for the presence of dental caries and plaque accumulation. Reliability of CPQ-G8-10 was investigated in a subsample of 58 children after 3 weeks. Results Questionnaire summary score test-retest reliability was 0.85 (intraclass correlation coefficient, 95% confidence interval (CI) ranging from 0.75 to 0.91) and internal consistency was 0.88 (Cronbach's alpha, lower limit of the 95% CI: 0.87). Validity of the CPQ-G8-10 questionnaire was supported by correlation coefficients with global ratings of oral health of − 0.40 (95% CI − 0.49 to − 0.31) and overall well-being of − 0.26 (95% CI − 0.33 to − 0.13) which met the expectations. Mean CPQ-G8-10 scores were statistically significantly higher in children with caries (dmft+DMFT > 0) compared with caries-free children (p = 0.02). Conclusions The German version of the CPQ8-10 was found to be reliable and valid in children aged 8 to 10 years. Clinical relevance These findings enable assessments of oral health-related quality of life in German speaking 8-to 10-year-old children.

Influence of caries and molar incisor hypomineralization on oral health-related quality of life in children

“…Caries and MIH are the most common diseases of the orofacial system for children in the age group analyzed [1]. The CPQ-G8-10 by Bekes et al [23], which is based on the questionnaire developed by the Canadian author Jokovic [16], was used to examine which of these conditions had a greater impact on the OHRQoL of children. The overall results showed that for both diseases, as clinical severity increased, subjectively perceived OHRQoL significantly worsened.…”

“…EAPD criteria were used to define the severity of MIH, divided into mild, moderate, and severe [6]. The first quantitative outcome variable was the OHRQoL, which was measured using the German version of the CPQ8-10 [23]. The CPQ-G8-10 contains 25 questions focusing on the respondent's oral health and well-being over the prior 4 weeks.…”

Impact of molar incisor hypomineralization on oral health–related quality of life in 8–10-year-old children

“…To assess the child’s OHRQoL, the validated German version of the CPQ8-10 was used [ 16 ]. The CPQ8-10 contains a total of 25 items which can be subdivided into four domains: oral symptoms (five items), functional limitations (five items), emotional well-being (five items), and social well-being (ten items).…”

Changes in oral health-related quality of life after treatment of hypersensitive molar incisor hypomineralization–affected molars with a sealing

“…The instrument is frequently used worldwide and has already been translated and validated in several countries. In our study, the German version was applied [ 19 ]. Originally, the CPQ8–10 was developed for children aged 8–10 years.…”

“…To assess the child’s OHRQoL before and at different time points after treatment, the validated German version of the CPQ8–10 was used [ 19 ]. The CPQ8–10 contains a total of 25 items which can be subdivided into four domains: oral symptoms (five items), functional limitations (five items), emotional well-being (five items), and social well-being (ten items).…”
