The aim of this study was to translate and evaluate the performance of an oral health related quality of life measure--an Arabic version of OHQoL-UK in three middle eastern countries: Syria, Egypt and Saudi Arabia.
Following forward and backwards translation of OHQoL-UK into Arabic and pilot testing the Arabic version among focus groups, a questionnaire containing the instrument was administered to 1,000 adults from the three Arab countries. In addition, the study participants were interviewed about their oral health status, experience of oral health problems in the past year, self-rating of oral health and also some socio-demographic information was collected.
Among the three study populations, variations in OHQoL-UK scores were apparent in relation to socio-demographic factors (p<0.01), self-reported number of teeth possessed (p<0.001) and experience of oral health problems in the past year (p<0.01) which supports the construct validity of the instrument. Furthermore, variations in OHQoL-UK scores were apparent in relation to self-rating of oral health status (p<0.01) which supports the criterion validity of the measure. The internal reliability of the instrument was high in the three groups with Cronbach alpha values of above 0.90, indicating good internal consistency.
The Arabic version of OHQoL-UK, an index of oral health related quality of life demonstrated satisfactory construct validity, criterion validity and internal reliability in Syria, Egypt and Saudi Arabia. This provides further evidence of the instrument's psychometric properties and its cross cultural use.
本研究旨在翻译并评估一项与口腔健康相关的生活质量测量工具——《英国口腔健康相关生活质量量表》阿拉伯语版在三个中东国家（叙利亚、埃及和沙特阿拉伯）的性能。
在将《英国口腔健康相关生活质量量表》进行前后向翻译为阿拉伯语并在焦点小组中对阿拉伯语版进行预测试之后，向来自这三个阿拉伯国家的1000名成年人发放了包含该量表的问卷。此外，研究参与者被询问了他们的口腔健康状况、过去一年中口腔健康问题的经历、口腔健康自我评分，还收集了一些社会人口统计学信息。
在这三个研究人群中，《英国口腔健康相关生活质量量表》得分在社会人口统计学因素（p<0.01）、自我报告的牙齿数量（p<0.001）以及过去一年中口腔健康问题的经历（p<0.01）方面存在明显差异，这支持了该工具的结构效度。此外，《英国口腔健康相关生活质量量表》得分在口腔健康状况自我评分方面存在明显差异（p<0.01），这支持了该测量方法的效标效度。该工具在三组中的内部信度较高，克朗巴哈α值均高于0.90，表明内部一致性良好。
《英国口腔健康相关生活质量量表》阿拉伯语版作为一种与口腔健康相关的生活质量指标，在叙利亚、埃及和沙特阿拉伯表现出令人满意的结构效度、效标效度和内部信度。这为该工具的心理测量特性及其跨文化应用提供了进一步的证据。
