In dentistry, measures of oral health-related quality of life (OHRQoL) provide essential information for assessing treatment needs, making clinical decisions and evaluating interventions, services and programmes. The two most common measures used to examine child OHRQoL today are the Child Perceptions Questionnaire at two ages, 8-10 and 11-14 (CPQ₈₋₁₀, CPQ₁₁₋₁₄). The reliability and validity of these two versions have been demonstrated together with that (more recently) of the short-form 16-item impact version of the CPQ₈₋₁₀. This study set out to examine the reliability and validity of the Child Oral Health Quality of Life Questionnaires (COHQOL) instruments the CPQ₈₋₁₀ and impact short-form CPQ₁₁₋₁₄ in 5-to-8-year-old New Zealand children, and to determine whether a single measure for children aged 5-14 is feasible.
A cross-sectional survey was conducted of 5-to-8-year-old children attending for dental treatment in community clinics in 2011. Children were examined for dental caries, with OHRQoL measured using the CPQ₈₋₁₀and short-form CPQ₁₁₋₁₄. Construct validity was evaluated by comparing mean scale scores across ordinal categories of caries experience; correlational construct validity was assessed by comparing mean CPQ scores across children's global ratings of oral health and well-being.
The 183 children (49.7% female) aged 5 to 8 years who took part in the study represent a 98.4% participation rate. The overall mean dmft was 6.0 (SD, 2.0 range 1 to 13). Both questionnaire versions detected differences in the impact of dental caries on quality of life, with the greatest scores in the expected direction. Both versions showed higher scores among those with poorer oral health. There was a very strong and positive correlation between CPQ₁₁₋₁₄ scores and CPQ₈₋₁₀ scores (Pearsons's r = 0.98; P < 0.01).
The performance of both versions of the COHQOL measures (CPQ₈₋₁₀ and short-form CPQ₁₁₋₁₄) appears to be acceptable in this younger age group, and this work represents the first stage in validating this questionnaire in a younger age group. It also further confirms that younger children are capable of providing their own perceptions of oral health impacts. The acceptability of the short-from CPQ₁₁₋₁₄ in this younger age group lends support to its use in children between ages 5 and 14.
在牙科领域，口腔健康相关生活质量（OHRQoL）的测量为评估治疗需求、做出临床决策和评估干预、服务和计划提供了重要信息。目前用于检查儿童 OHRQoL 的两种最常见的测量方法是在 8-10 岁和 11-14 岁时使用儿童感知问卷（CPQ₈₋₁₀、CPQ₁₁₋₁₄）。这两个版本的可靠性和有效性已经得到了证明，最近还证明了 CPQ₈₋₁₀的短式 16 项影响版本的可靠性和有效性。本研究旨在检验 CPQ₈₋₁₀和影响短式 CPQ₁₁₋₁₄在 5-8 岁新西兰儿童中的可靠性和有效性，并确定对于 5-14 岁儿童是否可以使用单一测量方法。
2011 年对在社区诊所接受牙科治疗的 5-8 岁儿童进行了横断面调查。对儿童进行了龋齿检查，使用 CPQ₈₋₁₀和短式 CPQ₁₁₋₁₄测量 OHRQoL。通过比较龋齿经历的有序类别中的平均量表得分来评估结构效度；通过比较儿童对口腔健康和幸福感的总体评价来评估相关结构效度。
参加研究的 183 名 5-8 岁儿童（49.7%为女性）代表了 98.4%的参与率。总体平均 dmft 为 6.0（SD，2.0 范围为 1 至 13）。两种问卷版本均检测到龋齿对生活质量的影响存在差异，得分方向与预期一致。口腔健康状况较差的儿童得分较高。CPQ₁₁₋₁₄ 评分与 CPQ₈₋₁₀ 评分之间存在非常强且呈正相关（Pearson's r = 0.98；P < 0.01）。
在这个年龄较小的群体中，两种 COHQOL 测量版本（CPQ₈₋₁₀和短式 CPQ₁₁₋₁₄）的表现似乎都可以接受，这是在年龄较小的群体中验证该问卷的第一步。它还进一步证实，年幼的儿童能够提供自己对口腔健康影响的看法。短式 CPQ₁₁₋₁₄ 在这个年龄较小的群体中的可接受性支持了其在 5 至 14 岁儿童中的使用。
