Boiko OV, Baker SR, Gibson BJ, Locker D, Sufi F, Barlow, APS, Robinson PG. Construction and validation of the quality of life measure for dentine hypersensitivity (DHEQ). J Clin Periodontol 2010; 37: 973–980. doi: 10.1111/j.1600‐051X.2010.01618.x. Abstract Aim: To develop and validate a condition specific measure of oral health‐related quality of life for dentine hypersensitivity (Dentine Hypersensitivity Experience Questionnaire, DHEQ). Materials and Methods: 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). Results: 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. Conclusions: 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.
