To assess the application of the Oral Impacts on Daily Performances (OIDP) index for use in three different language and cultural settings;
To develop a Spanish and Afrikaans version of the OIDP for use in the USA and South Africa and to assess its reliability and validity in three counties: UK, USA and South Africa.
Co-ordinated pilot studies using the OIDP questionnaire and clinical examination using WHO criteria in the three countries using cross-sectional convenience samples of children.
Two populations in each country: relatively well-off and more socially disadvantaged in three age groups 40 years+, 15-16 and 11-12 year-olds.
525 volunteers participated in the study; 154 in Texas, 177 in Bristol and 194 in Cape Town, the majority being females. The prevalence of oral impacts on daily performances varied between the three sites, with the sample in Bristol showing lower prevalence of 28.8% reporting at least one oral impact in the past six months. Difficulty eating was a common impact in all three sites, reported by 22.7% of the Texas sample, 18.6% of the Bristol sample and 33.0% of the Cape Town sample. Criterion and construct validity: the OIDP performed consistently well in all three sites. The combined dental caries status of the two lower age groups (12- and 16-year-olds) varied by site: Texas had the highest overall mean DMFT of 4.31, then Bristol with 3.07 and Cape Town the lowest at 2.89.
The OIDP index had excellent psychometric properties in the Cape Town and Texas samples and had an overall good performance in the Bristol sample. Potentially the index can be used for oral health needs assessment and planning services. Further studies using larger samples might provide information relevant to the revision of existing oral health care systems.
评估口腔影响日常生活性能（OIDP）指数在三种不同语言和文化背景下的应用；
为美国和南非开发西班牙语和南非荷兰语版的 OIDP，并在英国、美国和南非的三个国家评估其可靠性和有效性。
在三个国家使用 OIDP 问卷和 WHO 标准的临床检查，使用横断面便利样本的儿童进行协调试点研究。
每个国家有两个群体：在三个年龄组（40 岁以上、15-16 岁和 11-12 岁）中，相对富裕和更社会劣势。
525 名志愿者参加了这项研究；德克萨斯州有 154 人，布里斯托尔有 177 人，开普敦有 194 人，大多数是女性。过去六个月，三个地点的口腔对日常生活的影响的发生率有所不同，布里斯托尔的样本发生率较低，为 28.8%。在所有三个地点，进食困难都是一个常见的影响，德克萨斯州样本的 22.7%、布里斯托尔样本的 18.6%和开普敦样本的 33.0%报告了这一影响。标准和结构效度：OIDP 在所有三个地点的表现都非常一致。两个较低年龄组（12 岁和 16 岁）的综合龋齿状况因地点而异：德克萨斯州的总体平均 DMFT 最高，为 4.31，其次是布里斯托尔，为 3.07，开普敦最低，为 2.89。
OIDP 指数在开普敦和德克萨斯州样本中具有出色的心理测量特性，在布里斯托尔样本中总体表现良好。该指数可能可用于口腔健康需求评估和规划服务。使用更大样本的进一步研究可能会提供与现有口腔保健系统修订相关的信息。
