A questionnaire designed to measure oral health-related quality of life (OHRQOL) in adults and children was assessed for its factorial structure and reliability using data from the Second International Collaborative Study on Oral Health Outcomes in New Zealand, Poland and Germany. Principal component analysis with orthogonal and oblique rotation was applied. The three-factor structure hypothesized for the children's questionnaire (self-reported oral disease symptoms, perceived oral well-being, social and physical functioning) was confirmed in New Zealand and Poland, and two self-reported oral disease symptom dimensions emerged in Germany. Five factors instead of the three hypothesized were identified for adults: two dimensions of symptoms were identified, and social and physical functioning appeared to be independent dimensions of OHRQOL. Similarity between the factors was demonstrated in all three countries. The reliability of the questionnaire ranged from moderate to excellent depending on the dimension and the country. These findings provide preliminary evidence of the cross-cultural stability of the OHRQOL questionnaire in New Zealand, Poland and Germany, for both children and adults. Further investigations by the present authors of the properties of the instrument in other samples will focus on demonstrating the stability and replicability of the factor structure identified here.
使用来自新西兰、波兰和德国的第二次口腔健康结果国际合作研究的数据，对一份旨在测量成人和儿童口腔健康相关生活质量（OHRQOL）的问卷进行了因子结构和信度评估。应用了带有正交和斜交旋转的主成分分析。儿童问卷假设的三因素结构（自我报告的口腔疾病症状、感知的口腔幸福感、社会和身体功能）在新西兰和波兰得到了证实，而在德国出现了两个自我报告的口腔疾病症状维度。成人确定了五个因素而非假设的三个因素：确定了两个症状维度，社会和身体功能似乎是OHRQOL的独立维度。所有三个国家的因素之间都显示出相似性。问卷的信度根据维度和国家的不同，从中度到优秀不等。这些发现为OHRQOL问卷在新西兰、波兰和德国的儿童和成人中的跨文化稳定性提供了初步证据。本研究作者对该工具在其他样本中的特性进行的进一步调查将集中于证明此处确定的因子结构的稳定性和可重复性。
