BACKGROUND
The psychosocial impact of dental aesthetics questionnaire (PIDAQ) is an efficient tool for assessment of oral health-related quality of life (OHRQoL). It evaluates the effect of dental esthetics on the psychosocial status of young adults. This questionnaire has been translated to many languages so far. However, it has not yet been translated to Persian. This study aimed to assess the validity and reliability of the Persian version of PIDAQ for use among the young adults.
MATERIAL AND METHOD
The questionnaire was translated to Persian, back-translated to English and underwent cultural adaptation and pretesting. It was then filled out by 398 young adults (215 females and 183 males) between 18 to 30 years in Shiraz, Iran. The Persian version of PIDAQ along with the index of orthodontic treatment need-aesthetic component (IOTN-AC) and the perception of occlusion (POS) index were administered among participants to assess its discriminant validity.
RESULTS
Factor analysis extracted four domains and the factor loading of domains ranged from 0.479 to 0.837. The Cronbach's alpha for the Persian version of PIDAQ ranged from 0.809 to 0.886. The mean score for each of the domains and the total score for PIDAQ, classified according to IOTN-AC and POS, showed a significant difference. The mean score acquired by subjects requiring orthodontic treatment was significantly higher than the score acquired by those not requiring orthodontic treatment (P = 0.00).
CONCLUSION
The Persian version of PIDAQ has optimal validity, reliability and responsiveness for assessment of the psychosocial impact of malocclusion on the Iranian young adults.
背景
口腔美学问卷（PIDAQ）的心理社会影响是评估口腔健康相关生活质量（OHRQoL）的有效工具。它评估了牙齿美观对年轻成年人心理社会状态的影响。到目前为止，该问卷已经被翻译成多种语言，但尚未被翻译成波斯语。本研究旨在评估 PIDAQ 波斯语版本在年轻成年人中的有效性和可靠性。
材料和方法
问卷被翻译成波斯语，再被翻译回英语，并进行了文化适应和预测试。然后，在伊朗设拉子，由 398 名 18 至 30 岁的年轻人（215 名女性和 183 名男性）填写。参与者填写了 PIDAQ 波斯语版本以及正畸治疗需求指数-美学成分（IOTN-AC）和咬合感知指数（POS），以评估其判别效度。
结果
因子分析提取了四个领域，领域的因子负荷范围为 0.479 至 0.837。PIDAQ 波斯语版本的 Cronbach's alpha 范围为 0.809 至 0.886。根据 IOTN-AC 和 POS 对 PIDAQ 的每个领域和总分进行分类，得分存在显著差异。需要正畸治疗的受试者的平均得分明显高于不需要正畸治疗的受试者（P=0.00）。
结论
PIDAQ 波斯语版本具有评估伊朗年轻成年人错畸形心理社会影响的最佳有效性、可靠性和反应性。
