To develop and validate a condition specific measure of oral health-related quality of life for dentine hypersensitivity (Dentine Hypersensitivity Experience Questionnaire, DHEQ).
Questionnaire construction used a multi-staged impact approach and an explicit theoretical model. Qualitative and quantitative development and validation included in-depth interviews, focus groups and cross-sectional questionnaire studies in a general population (n=160) and a clinical sample (n=108).
An optimized DHEQ questionnaire containing 48 items has been developed to describe the pain, a scale to capture subjective impacts of dentine hypersensitivity, a global oral health rating and a scale to record effects on life overall. The impact scale had high values for internal reliability (nearly all item-total correlations >0.4 and Cronbach's α=0.86). Intra-class correlation coefficient for test-retest reliability was 0.92. The impact scale was strongly correlated to global oral health ratings and effects on life overall. These results were similar when DHEQ was validated in a clinical sample.
DHEQ shows good psychometric properties in both a general population and clinical sample. Its use can further our understanding of the subjective impacts of dentine sensitivity.
开发并验证用于牙本质敏感的特定口腔健康相关生活质量的衡量标准（牙本质敏感体验问卷，DHEQ）。
问卷构建采用多阶段影响方法和明确的理论模型。定性和定量开发和验证包括在一般人群（n=160）和临床样本（n=108）中进行深入访谈、焦点小组和横断面问卷调查研究。
开发了一个包含 48 个项目的优化的 DHEQ 问卷，用于描述疼痛、捕捉牙本质敏感的主观影响的量表、总体口腔健康评分和记录总体生活影响的量表。影响量表具有较高的内部可靠性（几乎所有项目总分相关系数>0.4，克朗巴赫的α=0.86）。测试重测信度的组内相关系数为 0.92。影响量表与总体口腔健康评分和生活总体影响高度相关。在临床样本中验证 DHEQ 时，结果相似。
DHEQ 在一般人群和临床样本中均具有良好的心理测量特性。它的使用可以进一步了解牙本质敏感性的主观影响。
