The aim of this study was to develop a psychometric instrument for assessment of orthodontic-specific aspects of quality of life. The study subjects, 194 young adults aged 18-30 years, were interviewed using a pool of 23 items dealing with the psychosocial impact of dental aesthetics. Self- and interviewer-rating of the dental aesthetic appearance of each subject were carried out using the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN). Additionally, the Perception of Occlusion Scale and a modification of the Dental Aesthetic Index (DAI) were applied. Factorial analyses identified four measures within the item pool, namely Dental Self-Confidence, Social Impact, Psychological Impact, and Aesthetic Concern. The factor structure was confirmed in an independent sample of 83 subjects aged 18-33 years. The reliabilities of the factor analysis-derived scales were between alpha (alpha) 0.85 and 0.91. They differed between respondents with varying severity of malocclusion, as assessed by subject and interviewer ratings. The results suggest that the proposed instrument, termed the 'Psychosocial Impact of Dental Aesthetics Questionnaire' (PIDAQ), meets the criteria of factorial stability across samples and criterion-related validity and reliability, and might be a promising tool for further research and clinical application in orthodontics.
本研究的目的是开发一种用于评估正畸特定生活质量方面的心理测量工具。研究对象为194名年龄在18至30岁之间的年轻人，使用一组23个涉及牙齿美观心理社会影响的项目进行访谈。使用正畸治疗需求指数（IOTN）的美学成分（AC）对每个受试者的牙齿美观外观进行自评和访谈者评分。此外，还应用了咬合感知量表和改良的牙齿美学指数（DAI）。因子分析在项目库中确定了四个指标，即牙齿自信心、社会影响、心理影响和美学关注。在一个由83名年龄在18至33岁之间的受试者组成的独立样本中证实了因子结构。因子分析得出的量表的信度在α系数0.85至0.91之间。根据受试者和访谈者的评分，它们在错牙合畸形严重程度不同的受访者之间存在差异。结果表明，所提出的工具，即“牙齿美观心理社会影响问卷”（PIDAQ），符合跨样本因子稳定性以及与标准相关的效度和信度标准，可能是正畸学进一步研究和临床应用的一个有前景的工具。
