The FACE-Q Craniofacial Module is a patient-reported outcome measure (PROM) developed for children and young adults with craniofacial conditions. We hypothesised that some of its scales may be applicable to other populations. The aim of this study was to assess the validity and reliability of FACE-Q scales for patients with dental malocclusions.
The FACE-Q Dental Module includes 5 scales from the Craniofacial Module that measure appearance (Face, Jaws, Smile and Teeth) and function (Eating/Drinking). Data were collected from patients aged 8-29 years who presented with a dental malocclusion (pre-treatment) or 1-2 years after orthodontic treatment (post-treatment) at a large university-based orthodontic specialty clinic in Canada between September 2018 and March 2020. Patients completed a paper questionnaire booklet, and data were entered into a Research Electronic Data Capture (REDCap) survey. The psychometric analysis was performed using Rasch Measurement Theory (RMT) analysis.
The sample of 434 patients was aged 9 to 29 years, with 249 female and 185 male participants. The sample included 252 pre-treatment and 182 post-treatment patients. The 4 appearance scales evidenced strong psychometric performance; all 37 items had ordered thresholds with good item fit to the Rasch model. Reliability was high, with person separation index and Cronbach alpha values, with and without extremes ≥ 0.86. As hypothesised, those participants who had a major difference in appearance, and those who reported liking their appearance less, scored lower on the appearance scales (p < 0.001). In the RMT analysis, the Eating/Drinking scale evidenced low reliability and poor targeting with close to 40% of particpants scoring at the ceiling.
The FACE-Q Dental Module provides a means to collect evidence-based outcomes data from children and young adults who undergo orthodontic care for dental malocclusions.
面部质量问卷（FACE-Q）颅面模块是一种针对患有颅面疾病的儿童和年轻人开发的患者报告结局测量工具（PROM）。我们假设其某些量表可能适用于其他人群。本研究的目的是评估FACE-Q量表对牙列不齐患者的有效性和可靠性。
FACE-Q牙科模块包括来自颅面模块的5个量表，用于测量外观（面部、颌骨、微笑和牙齿）和功能（饮食）。2018年9月至2020年3月期间，在加拿大一家大型大学正畸专科诊所，收集了8至29岁患有牙列不齐（治疗前）或正畸治疗后1至2年（治疗后）的患者的数据。患者完成一份纸质问卷手册，数据录入研究电子数据采集（REDCap）调查。使用拉施测量理论（RMT）分析进行心理测量分析。
434名患者的样本年龄为9至29岁，其中女性249名，男性185名。样本包括252名治疗前患者和182名治疗后患者。4个外观量表显示出良好的心理测量性能；所有37个项目都有有序的阈值，与拉施模型的项目拟合良好。可靠性很高，人员分离指数和克朗巴赫α值（有或无极端值）≥0.86。正如假设的那样，那些外观有重大差异的参与者以及那些表示不太喜欢自己外观的参与者，在外观量表上得分较低（p<0.001）。在RMT分析中，饮食量表显示出低可靠性和差的针对性，近40%的参与者得分达到上限。
FACE-Q牙科模块提供了一种手段，可从接受牙列不齐正畸治疗的儿童和年轻人中收集基于证据的结局数据。
