| Research Abstract |
Oral health-related quality of life (OHQOL) has been an area of growing research interest in dentistry in recent years. The Oral Health Impact Profile (OHIP) was selected as an appropriate measure for studying the OHQOL in a Japanese population. The original OHIP was translated into Japanese. To validate the Japanese version of the Oral Health Impact Profile (OHIP-J) for use among young and middle-aged adults, I analyzed using data involved items for the OHIP-J and selfrated oral health, denture wearing, number of missing teeth, work type, occupational rank, gender, and age. The adjusted total OHIP-J scores for respondents who rated their oral health as poor were higher than those who did not. In addition, the variable of missing teeth was significantly associated with the OHIP-J total and subscale scores independent of gender, age and denture wearing. These findings suggest that the OHIP-J is suitable for assessing the Oral health-related quality of life of young and middle-aged adults in Japan. However, the translation process did not strictly adhere to these recommended guidelines. In this respect the OHIP-J had limitations for the use for cross-cultural research.
Because the OHIP consists of 49 items grouped into seven subscales lengthily a short-form version of OHIP-J was derived for use in young and middle-aged adults, and to evaluate its properties. We derived a subset of 18 items from OHIP-J (OHIP-JA18), grouped into four subscales : "functional limitation", "physical pain", "psychological discomfort", and "disability & handicap". The OHIP-JA18 captures four subscales that are based on a new conceptual framework, a simplified Locker's adaptation for oral health of the ICIDH model of health OHIP-JA18 demonstrated acceptable measurement parameters (internal consistency floor effect, construct validity, and responsiveness) to justify its use in outcome assessment for the OHQOL of young and middle-aged Japanese workers.
