The aim of this paper is to develop a short version of the Japanese OHIP (OHIP-J) appropriate for use in young and middle-aged adults, and to evaluate its properties using cross-sectional data.
A study population of 8,658 workers aged 20-59 years rated their oral health by means of a self-administered questionnaire. Using a factor analysis approach, a shortened version of OHIP-J was derived. Internal consistency, floor effect, and construct validity were determined.
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". All four subscales had acceptable internal consistency (Cronbach alpha > 0.79). OHIP-JA18 demonstrated an acceptable floor effect, which was determined by the proportion of subjects who obtained a 0 score (< 30%); however, the floor effect of the ordinary shortened version based on OHIP-14 (OHIP-J14) was not acceptable. We confirmed the conceptual framework of OHIP-JA18 that "disability & handicap" is affected by "functional limitation", "physical pain" and "psychological discomfort", because the model fitted the data moderately well by structural equation modeling (SEM) analysis (GFI = 0.90, RMSEA = 0.08).
OHIP-JA18 demonstrated acceptable measurement parameters to justify its use in outcome assessment for oral health related quality of life (OHQOL) in young and middle-aged adults in Japanese workers. Further studies will be needed to evaluate an intervention such as worksite health promotion.
本文旨在开发一个适用于中青年成年人的日本口腔健康影响程度量表（OHIP-J）简版，并使用横断面数据评估其特性。
8658名年龄在20 - 59岁的在职人员通过自行填写问卷对其口腔健康状况进行评分。采用因子分析方法得出OHIP-J的简版。确定其内部一致性、地板效应和结构效度。
我们从OHIP-J中得出了一个包含18个条目的子集（OHIP-JA18），分为四个子量表：“功能受限”、“身体疼痛”、“心理不适”以及“残疾与障碍”。所有四个子量表都具有可接受的内部一致性（Cronbach's α>0.79）。OHIP-JA18表现出可接受的地板效应，该效应由得0分的受试者比例确定（<30%）；然而，基于OHIP-14的普通简版（OHIP-J14）的地板效应不可接受。我们通过结构方程模型（SEM）分析证实了OHIP-JA18的概念框架，即“残疾与障碍”受“功能受限”、“身体疼痛”和“心理不适”影响，因为该模型对数据拟合程度适中（GFI = 0.90，RMSEA = 0.08）。
OHIP-JA18展示了可接受的测量参数，证明其可用于评估日本在职中青年成年人与口腔健康相关生活质量（OHQOL）的结局。还需要进一步研究来评估诸如工作场所健康促进等干预措施。
