ABSTRACT
"nBackground: 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. "nMethods: 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. "nResults: 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. "nConclusions: The Persian version of OHIP-14 is a precise, valid and reliable instrument for assessing oral health-re­lated quality of life among Persian population
