赫尔老年人口腔健康评价指数与口腔健康影响程度量表评价中国西南地区农村中老年人口腔生存质量的对比研究
Comparison of geriatric oral health assessment index and oral health impact profile-14 as measures of oral healthrelated quality of life of middle-aged and elderly individuals in southwest China

摘要： 目的 使用赫尔老年人口腔健康评价指数（GOHAI）和口腔健康影响程度（OHIP-14）量表评价中国西南地区农村中老年人的口腔健康生存质量，检验两量表信度，选出更适合评价中老年人口腔健康生存质量的量表。方法 随机抽取四川青川县和贵州习水县45岁以上中老年人，进行入户面对面的GOHAI和OHIP-14量表问卷调查，采用配对样本t检验，比较两量表在各个维度中老年人的得分，并分别计算两量表的克朗巴哈值进行信度比较。结果 GOHAI和OHIP-14量表对同一对象的口腔健康生存质量评价上一致性较高。中年人和老年人在这2个量表中各维度的得分中，除了GOHAI量表的心理维度得分无差异之外，其他维度得分在两表中均存在差异。信度分析发现OHIP-14量表内在稳定性和可靠性更高。结论 OHIP-14量表更适用于评价中老人的口腔健康生存质量。
Abstract: Objective This study compares oral health-related quality of life among middle-aged and elderly individuals in southwest China by geriatric oral health assessment index(GOHAI) and oral health impact profile-14(OHIP-14) scales, to test the reliability of GOHAI and OHIP-14 scales, and to select the more effective scale in evaluating oral health-related quality of life of rural middle-aged and elderly individuals. Methods Surveys with OHIP-14 and GOHAI scales were conducted face-to-face among rural middle-aged and elderly individuals above 45 years old from Qingchuan Sichuan and Xishui Guizhou randomly. Differences between the two scales were compared by Paired sample t-test(P=0.05). Reliability was evaluated by Cronbach’s alpha. Results GOHAI and OHIP-14 scales were highly consistent in assessing oral health-related quality of life in the same subject. GOHAI and OHIP-14 scores of middle-aged and elderly people showed differences in each dimension except for the psychological dimension. Reliability analysis showed that OHIP-14 is inherently more stable and reliable. Conlusion OHIP-14 scale is more suitable for the evaluation of oral health quality of life among middle-aged and elderly individuals in rural southwest China
