PURPOSE
The Oral Health Impact Profile (OHIP) is currently the most widely used oral health-related quality of life (OHRQoL) instrument. The study validated the English-language 5-item OHIP by investigating its psychometric properties of dimensionality, reliability, and validity in the adult general population.
METHODS
In 405 subjects (mean age 45+15.7 years, 63% female) from the 2014 Minnesota State Fair, dimensionality was investigated by confirmatory factor analysis. Construct validity was assessed by using a structural equation model correlating OHRQoL and self-reported global oral health status. Reliability was calculated using Cronbach's alpha for OHIP5 total scores.
RESULTS
In the confirmatory factor analysis, the unidimensional model fit OHIP5 well as indicated by fit indices (RMSEA: 0.07, SRMR: 0.03, comparative fit indices: >0.95). In the structural equation model, self-reported global oral health status correlated with 0.46 with the latent OHRQoL factor, indicating sufficient construct validity. Cronbach's alpha, a measure of score reliability, was "satisfactory" with 0.75.
CONCLUSION
We validated the English-language version of OHIP5 in the adult general population. Ultrashort instruments such as the 5-item OHIP provide a conceptually appealing and technically feasible opportunity to measure the impact of oral disorders and dental interventions in settings such as general dental practice where the burden to collect and interpret OHRQoL information needs to be minimized.
目的
口腔健康影响量表（OHIP）目前是使用最广泛的口腔健康相关生活质量（OHRQoL）工具。本研究通过调查其在普通成年人群中的维度、信度和效度的心理测量学特性，验证了英文版 5 项 OHIP。
方法
在明尼苏达州 2014 年博览会的 405 名受试者（平均年龄 45+15.7 岁，63%为女性）中，通过验证性因子分析来研究维度。通过结构方程模型将 OHRQoL 与自我报告的整体口腔健康状况相关联，来评估结构有效性。使用 Cronbach's alpha 计算 OHIP5 总分的可靠性。
结果
在验证性因子分析中，作为拟合指数的一维模型（RMSEA：0.07，SRMR：0.03，比较拟合指数：>0.95）很好地拟合了 OHIP5。在结构方程模型中，自我报告的整体口腔健康状况与潜在 OHRQoL 因子相关系数为 0.46，表明具有足够的结构有效性。Cronbach's alpha 是衡量得分可靠性的指标，其值为“满意”的 0.75。
结论
我们在普通成年人群中验证了英文版 OHIP5。像 5 项 OHIP 这样的超短量表为在一般牙科实践等环境中测量口腔疾病和牙科干预的影响提供了一个有吸引力的概念和可行的技术机会，在这些环境中，需要尽量减少收集和解释 OHRQoL 信息的负担。
