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.
The original English version of the CPQ8-10 questionnaire was translated into German (CPQ-G8-10) by a forward-backward 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.
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).
The German version of the CPQ8-10 was found to be reliable and valid in children aged 8 to 10 years.
These findings enable assessments of oral health-related quality of life in German speaking 8- to 10-year-old children.
本研究旨在开发适用于 8 至 10 岁儿童的儿童感知问卷（CPQ-G8-10）的德文版本，该问卷用于测量口腔健康相关生活质量，并评估该工具的信度和效度。
采用正向-反向翻译法将 CPQ8-10 问卷的原始英文版本翻译成德文（CPQ-G8-10）。奥地利维也纳儿科牙科系共招募了 409 名 8 至 10 岁的儿童参加本研究。儿童自行完成 CPQ-G8-10 问卷，并接受临床检查以确定是否存在龋齿和菌斑积聚。在另一个 58 名儿童的子样本中，3 周后对 CPQ-G8-10 的信度进行了调查。
问卷综合评分的重测信度为 0.85（组内相关系数，95%置信区间（CI）范围为 0.75 至 0.91），内部一致性为 0.88（克朗巴赫 α，95%CI 下限：0.87）。CPQ-G8-10 问卷的有效性得到了支持，与口腔健康总体评价的相关系数为 -0.40（95%CI -0.49 至 -0.31），与总体幸福感的相关系数为 -0.26（95%CI -0.33 至 -0.13），这与预期相符。与无龋齿儿童相比，患有龋齿（dmft+DMFT＞0）的儿童 CPQ-G8-10 评分明显更高（p=0.02）。
CPQ8-10 的德文版本在 8 至 10 岁儿童中具有可靠性和有效性。
这些发现使德国 8 至 10 岁儿童的口腔健康相关生活质量评估成为可能。
