背景：口腔健康相关的生活质量（OHQoL）被认为是一个多维的结构。在这里，我们的目的是调查的尺寸结构的OHQoL测量的西班牙语版本的口腔影响日常表现（OIDP）和口腔健康的影响简介（OHIP-14）的调查问卷，同时应用。方法：我们招募了一个连续的样本270名健康的西班牙工人访问就业风险预防中心的例行体检。OHIP-14由参与者自行完成，但OIDP是在面对面的访谈中完成的。进行探索性因素分析（EFA），以确定两种工具评估的OHQoL结构的基本维度。这一析因结构，后来证实了验证性因素分析（CFA）使用几个估计的拟合优度index.Results：EFA和CFA确定，并分别确认了一组3个基本因素，在这两个问卷中，可以解释为功能限制，疼痛不适，和心理社会的影响。实现的模型被认为是适合这两种工具，但析因结构更清晰的OIDP.Conclusions：结果提供了证据的潜在因素评估的OIDP和OHIP-14，这表明OHQoL是一个三维结构的构造等效。对这三个因素的影响在两个指标之间是一致的，疼痛不适的患病率最高，其次是心理社会影响和功能限制。
Background: Oral health-related quality of life (OHQoL) is conceived as a multidimensional construct. Here our aim was to investigate the dimensional structure of OHQoL as measured by the Spanish versions of the Oral Impacts on Daily Performance (OIDP) and the Oral Health Impact Profile (OHIP-14) questionnaires applied simultaneously.Methods: We recruited a consecutive sample of 270 healthy Spanish workers visiting the Employment Risk Prevention Centre for a routine medical check-up. OHIP-14 was self-completed by participants but the OIDP was completed in face-to-face interviews. An Exploratory Factor Analysis (EFA) was performed to identify the underlying dimensions of the OHQoL construct assessed by both instruments. This factorial structure was later confirmed by Confirmatory Factor Analysis (CFA) using several estimators of goodness of fit indices.Results: EFA and the CFA identified and respectively confirmed a set of 3 underlying factors in both questionnaires that could be interpreted as functional limitation, pain-discomfort, and psychosocial impacts. The model achieved was seen to fit properly for both instruments, but the factorial structure was clearer for the OIDP.Conclusions: The results provide evidence for construct equivalence in the latent factors assessed by both OIDP and OHIP-14, suggesting that OHQoL is a three-dimensional construct. The prevalence of impact on these three factors was coherent between both indicators, pain-discomfort having the highest prevalence, followed by psychosocial impact, and functional limitation.
