This study aims to translate and evaluate the performance of a Chinese version of the Child Oral Health-related Quality of Life (COHQoL) measure composed of the Child Perception Questionnaire (CPQ), Parental Perception Questionnaire (PPQ), and Family Impact Scale (FIS).
Chinese versions of the measures were derived through a forward-backward translation. A consecutive sample of 168 children attending paediatric dental and orthodontic clinics in Hong Kong were recruited along with their attending primary caregiver. Children self-completed the 37-item CPQ and their attending primary caregiver self-completed the 31-item PPQ and 14-item FIS consecutively and independently. Reassessments were conducted prior to their next appointment.
CPQ, PPQ, and FIS scores were associated with children's global rating of oral health (P < 0.05) and oral well-being (P < 0.05) supporting their construct validity. In addition, variations in CPQ, PPQ, and FIS were apparent with respect to patient group (P < 0.05) supporting their ability to distinguish between patient groups. Cronbach alpha values (internal reliability) and intraclass correlation coefficient values (test-retest reliability) for the three measures were > 0.80.
A Chinese version of the three components of the COHQoL measure was developed with minor modifications. In psychometric testing, the validity of the three components was supported and they demonstrated acceptable reliability.
本研究旨在翻译并评估由儿童感知问卷（CPQ）、家长感知问卷（PPQ）和家庭影响量表（FIS）组成的中文版儿童口腔健康相关生活质量（COHQoL）测评工具的性能。
通过正向-反向翻译得出测评工具的中文版。连续招募了168名在香港儿科牙科和正畸诊所就诊的儿童及其陪同的主要照顾者。儿童独立完成37项的CPQ，其陪同的主要照顾者独立完成31项的PPQ和14项的FIS。在他们下次预约就诊前进行重新评估。
CPQ、PPQ和FIS得分与儿童对口腔健康的总体评价（P < 0.05）和口腔健康状况（P < 0.05）相关，支持其结构效度。此外，CPQ、PPQ和FIS在患者组之间存在明显差异（P < 0.05），支持其区分不同患者组的能力。这三项测评工具的Cronbach α值（内部信度）和组内相关系数值（重测信度）均> 0.80。
对COHQoL测评工具的三个组成部分进行了微调后开发出了中文版。在心理测量测试中，这三个组成部分的效度得到了支持，并且显示出可接受的信度。
