To assess the association between scores on the Child Perceptions Questionnaire for 11-14 year olds (CPQ11-14) and clinical and self-perceived measures of malocclusion.
Children were recruited from an orthodontic clinic just prior to starting orthodontic treatment. They completed a copy of the CPQ11-14 and a short questionnaire concerning their feelings about the condition of their teeth. Study models were taken and rated according to the Dental Aesthetic Index (DAI) and the Peer Assessment Rating (PAR) index by two sets of three examiners. Intra and inter-rater reliabilities for the two sets of examiners ranged from 0.80 to 0.99. CPQ11-14 scores were calculated for the full 35-item version and for 16 and 8-item short forms by summing the item response codes. The association between these scores, the DAI and PAR ratings and self-perceived measures of malocclusion were examined using appropriate parametric and nonparametric tests.
Complete data were collected for 141 children, 63 boys and 78 girls. The mean age was 12.5 (SD = 1.0). DAI scores ranged from 17.0 to 58.0 with a mean of 35.0 (SD = 8.0). The distribution of subjects across the four severity categories was minor/none - 6.6%, definite - 35.2%, severe - 15.6% and handicapping 42.6%. PAR scores ranged from 8.0 to 66.0 with a mean of 31.4 (SD = 11.1). Eight percent had scores of 50 or above indicating marked deviation from an ideal occlusion. Both the long and the short forms of the CPQ11-14 identified substantial variability in the impacts of malocclusion. Correlations between CPQ11-14 scores and the orthodontic indices ranged from 0.26 to 0.31 (P < 0.01). There was a clear gradient in CPQ11-14 scores across four categories of the PAR based on quartiles. The gradient across the DAI categories was less clear. There were significant associations between all CPQ11-14 scores and the children's self-ratings of oral health, ratings of the extent to which the condition of the teeth affected life overall and expressions of happiness with the appearance and arrangement of the teeth.
The results provide some evidence of the validity of the CPQ11-14 when used with children needing orthodontic treatment. However, because clinical samples are biased the study needs to be repeated in different treatment settings in order to confirm the utility of the measure.
评估11 - 14岁儿童感知问卷（CPQ11 - 14）得分与错颌畸形的临床及自我感知测量指标之间的关联。
在正畸治疗开始前，从正畸诊所招募儿童。他们完成一份CPQ11 - 14问卷以及一份关于其对牙齿状况感受的简短问卷。制取研究模型，并由两组每组三名检查者根据牙齿美学指数（DAI）和同伴评估等级（PAR）指数进行评分。两组检查者的组内及组间信度范围为0.80至0.99。通过对项目反应编码求和，计算CPQ11 - 14完整35项版本以及16项和8项简短版本的得分。使用适当的参数检验和非参数检验来检查这些得分、DAI和PAR评分以及错颌畸形自我感知测量指标之间的关联。
收集了141名儿童的完整数据，其中63名男孩，78名女孩。平均年龄为12.5岁（标准差 = 1.0）。DAI得分范围为17.0至58.0，平均分为35.0（标准差 = 8.0）。在四个严重程度类别中，受试者的分布情况为轻度/无——6.6%，明确——35.2%，重度——15.6%，致残——42.6%。PAR得分范围为8.0至66.0，平均分为31.4（标准差 = 11.1）。8%的儿童得分在50分及以上，表明明显偏离理想咬合。CPQ11 - 14的长版和短版均显示错颌畸形影响存在显著差异。CPQ11 - 14得分与正畸指数之间的相关性范围为0.26至0.31（P < 0.01）。基于四分位数的PAR四个类别中，CPQ11 - 14得分存在明显梯度。DAI类别之间的梯度不太明显。所有CPQ11 - 14得分与儿童对口腔健康的自我评分、牙齿状况对整体生活影响程度的评分以及对牙齿外观和排列的满意度之间均存在显著关联。
结果为CPQ11 - 14用于正畸治疗需求儿童时的有效性提供了一些证据。然而，由于临床样本存在偏差，该研究需要在不同治疗环境中重复进行，以确认该测量方法的效用。
