validation of a persian version of the oral health impact profile (ohip-14)

background: the oral health-related quality of life indicators are increasingly used to measure the impact of the oral condi­tions on quality of life. one of the most used indicators is the oral health impact profile (ohip-14), but it has never been ap­plied in iran. the aim of this study was to validate the usage of ohip-14 among iranians. methods: a cross-sectional study was performed in kerman (iran). a consecutive sample (n= 400) of the kerman dental school clinics attending patients participated in this study. all participants self-completed the translated ohip-14. reliabil­ity analyses, validity tests, and responsiveness were carried out to evaluate the psychometric properties of the ohip-14. results: the reliability coefficient (cronbach's alpha) of the ohip-14 was above the recommended 0.7 threshold and consid­ered excellent (alpha: 0.85). the coefficient of the test-retest reliability measured by icc was 0.88 (ci 95%: 0.80-0.93). poorer oral condition was strongly associated with ohip scores of the patients, supporting construct validity. more­over, for evaluation of responsiveness, the es was measured to be 0.43 and the srm was 0.67. conclusions: the persian version of ohip-14 is a precise, valid and reliable instrument for assessing oral health-re­lated quality of life among persian population
