The aim of this study was to determine the frequency of oral health-related quality of life (OHRQoL) impairment and to establish norm values for the German version of the Child Perceptions Questionnaire (CPQ-G11-14, 35 questions) in the general population aged 11 to 14 years.
Data were collected in a national survey (n=1,597, mean age: 12.5 ± 1.2 years, 49.3% female) and subjects sampled using a multistage technique. OHRQoL was measured with the CPQ-G11-14, which was presented in a personal interview. Norm values were computed for the CPQ-G11-14 summary score (simple sum of all item responses). The CPQ-G11-14 summary score distribution was described by empirical cumulative distribution functions. Because orthodontic treatment was closely associated with CPQ-G11-14 summary scores, percentile-based norms were stratified by this variable.
The CPQ-G11-14 mean was 12.6 ± 15.9 units. There was no influence of age (p>0.05) or gender (p>0.05) on the CPQ-G summary scores, but the summary scores varied according to orthodontic treatment status (p<0.001). Among the general population sample, CPQ-G11-14 scores of the 50% less-impaired subjects were ≤7. The same percentage of subjects undergoing orthodontic treatment had scores of ≤13 and those without orthodontic treatment had scores of ≤5. We observed scores of ≤32 points in 90% of the population. That figure was ≤50 points for subjects undergoing orthodontic treatment and ≤21 points for those without orthodontic treatment. The most frequent problems the children and adolescents reported (CPQ-G answers "often" and "very often") were "breathing through the mouth" (13.0%), "mouth sores" (4.4%) and "bad breath" (4.3%).
The norm values we present provide a frame of reference for future cross-sectional studies in the general population and in patient populations with specific oral conditions when measuring OHRQoL by CPQ-G11-14 in children and adolescents aged 11 to 14 years old.
本研究旨在确定口腔健康相关生活质量（OHRQoL）受损的频率，并建立11至14岁普通人群中德文版儿童感知问卷（CPQ-G11-14，35个问题）的常模值。
数据收集于一项全国性调查（n = 1597，平均年龄：12.5±1.2岁，49.3%为女性），采用多阶段技术对受试者进行抽样。使用CPQ-G11-14测量OHRQoL，该问卷通过个人访谈呈现。计算CPQ-G11-14总分（所有项目回答的简单总和）的常模值。CPQ-G11-14总分分布通过经验累积分布函数进行描述。由于正畸治疗与CPQ-G11-14总分密切相关，基于百分位数的常模按此变量进行分层。
CPQ-G11-14的平均值为12.6±15.9分。年龄（p>0.05）或性别（p>0.05）对CPQ-G总分无影响，但总分因正畸治疗状况而异（p<0.001）。在普通人群样本中，受损程度较低的50%受试者CPQ-G11-14得分≤7分。接受正畸治疗的受试者中相同比例的得分≤13分，未接受正畸治疗的受试者得分≤5分。我们观察到90%的人群得分≤32分。接受正畸治疗的受试者该数值≤50分，未接受正畸治疗的受试者≤21分。儿童和青少年报告的最常见问题（CPQ-G回答“经常”和“非常经常”）是“口呼吸”（13.0%）、“口疮”（4.4%）和“口臭”（4.3%）。
我们给出的常模值为未来在普通人群以及患有特定口腔疾病的患者群体中，使用CPQ-G11-14测量11至14岁儿童和青少年的OHRQoL时的横断面研究提供了参考框架。
