AimWhile the importance of gingival aesthetics is increasingly recognized, a questionnaire quantifying its psychosocial impact is still lacking. We have adapted the validated Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) for the gingival context. This study's aim was to develop a new Psychosocial Impact of Gingival Aesthetics Questionnaire (PIGAQ) and test its validity for the general population in Spain, exploring the underlying dimensions of the construct assessed.Materials and MethodsThe PIDAQ was adapted to address gingival aesthetics. PIGAQ (23 items) was completed by 200 patients aged from 18 to 85 years, and socio‐demographic variables were recorded. The four‐dimensional structure of the PIDAQ was respected, adapting the subscales to focus on the gingiva. Descriptive analysis, assessments of reliability and validity and an exploratory factor analysis were performed.ResultsThe revised PIGAQ (now containing 20 items) has a Cronbach's alpha coefficient of 0.88 with four underlying factors explaining 61.5% of the total variance. Three items (SI‐1, PI‐2 and PI‐5) were eliminated because of unacceptable fit indices. The Cronbach's alpha coefficients for the subscales are as follows: Gingival Self‐Confidence, 0.85; Social Impact, 0.84; Psychological Impact, 0.79; and Aesthetic Concern, 0.76.ConclusionPIGAQ is a reliable and potentially valid instrument for assessing psychosocial perceptions of gingival aesthetics. The scale was shown to have a satisfactory factor structure and level of internal consistency.

评估牙龈美学社会心理影响的新问卷的验证 （PIGAQ）


目的虽然牙龈美学的重要性越来越得到认可，但仍然缺乏量化其社会心理影响的问卷。我们针对牙龈环境调整了经过验证的牙科美学社会心理影响问卷 （PIDAQ）。本研究的目的是开发一种新的牙龈美学社会心理影响问卷 （PIGAQ），并测试其对西班牙普通人群的有效性，探索所评估结构的潜在维度。材料和方法PIDAQ 适用于牙龈美学问题。PIGAQ（23 项）由 200 名年龄在 18 至 85 岁之间的患者完成，并记录了社会人口学变量。PIDAQ 的四维结构受到尊重，调整分量表以专注于牙龈。进行描述性分析、信效度评估和探索性因子分析。结果修订后的 PIGAQ（现在包含 20 个项目）的 Cronbach's alpha 系数为 0.88，其中 4 个基本因子解释了 61.5% 的总方差。三个项目 （SI-1 、 PI-2 和 PI-5） 由于不可接受的拟合指数而被淘汰。分量表的 Cronbach's alpha 系数如下：牙龈自信心，0.85;社会影响，0.84;心理影响，0.79;和 Aesthetic Concern， 0.76.结论PIGAQ 是评估牙龈美学的社会心理感知的可靠且可能有效的工具。该量表显示出令人满意的因子结构和内部一致性水平。
