The Oral Health Impact Profile (OHIP) is a measure of oral-health-related quality of life developed in Australia but being used increasingly in other populations. In view of the culturally specific nature of peoples' perceptions of health, if we are to make between-population comparisons of oral-health-related quality of life, cross-cultural equivalency of the relevant instruments needs to be verified. A study was therefore undertaken to compare item weights generated by an Australian sample with those generated by a sample of English-speaking Canadians and another of French-speaking Canadians. In addition, within-group comparisons by age were performed. The items and subscales used for the 2 Canadian samples were identical to those developed in Australia, although a formal French translation was used for the French-speaking sample. The method used for the generation of weights was Thurstone's paired-comparison technique, based on the judgments of convenience samples of subjects drawn from each of the three cultural settings. Comparisons were made by means of intra-subscale weight rankings and magnitude. Spearman's rank correlations of r> or =0.6 were found for 16/21 between-group comparisons and for 12/21, 19/21, and 8/21 within-group comparisons made by age in Australia, Ontario, and Quebec, respectively. Comparisons of the magnitudes of weights found that, even when items were ranked similarly, magnitudes could be quite different. These results suggest a reasonable degree of cross-cultural consistency, and hence validity, for the OHIP.
口腔健康影响概况（OHIP）是一种衡量与口腔健康相关生活质量的指标，它由澳大利亚开发，但在其他人群中的使用越来越多。鉴于人们对健康的认知具有文化特异性，如果我们要对不同人群的口腔健康相关生活质量进行比较，就需要验证相关工具的跨文化等效性。因此，开展了一项研究，比较澳大利亚样本生成的项目权重与讲英语的加拿大人样本和讲法语的加拿大人样本生成的项目权重。此外，还按年龄进行了组内比较。用于两个加拿大样本的项目和子量表与澳大利亚开发的项目和子量表相同，不过对讲法语的样本使用了正式的法语翻译。生成权重所采用的方法是瑟斯顿的配对比较技术，该技术基于从三种文化背景中抽取的方便样本的判断。通过子量表内权重排名和大小进行比较。在澳大利亚、安大略省和魁北克省，分别有16/21的组间比较以及12/21、19/21和8/21的按年龄进行的组内比较发现斯皮尔曼等级相关系数r≥0.6。权重大小的比较发现，即使项目排名相似，权重大小也可能有很大差异。这些结果表明OHIP具有合理程度的跨文化一致性，因此具有有效性。
