Abstract

OBJECTIVES

The aim of this study was to evaluate the reliability and validity of the Chinese version of the Oral Health Impact Profile for edentulous subjects (OHIP-EDENT-C).

METHODS

After translation and cross-cultural adaptation following international guidelines, 162 complete denture wearers were recruited to complete the questionnaire. The reliability of the OHIP-EDENT-C was evaluated using internal consistency and test-retest methods. The validity of the OHIP-EDENT-C was analyzed by construct validity and convergent validity. Construct validity was determined based on factor analysis and convergent validity by analyzing the correlation between OHIP-EDENT-C subscale scores and the global question.

RESULTS

Cronbach's alpha value (internal reliability) for the total OHIP-EDENT-C score was 0.972, and the intraclass correlation coefficient value (test-retest reliability) was 0.763 (similar to the original OHIP-EDENT). Construct validity was determined by factor analysis, extracting five factors, accounting for 74.31 % of the variance. All items had factor loadings above 0.40. In terms of convergent validity, the OHIP-EDENT-C subscale was significantly highly correlated to the global question.

CONCLUSION

The results suggest that the OHIP-EDENT-C is a reliable and valid measure to evaluate OHRQoL for edentulous subjects in China.

摘要

目的

本研究旨在评估中文版无牙颌患者口腔健康影响程度量表（OHIP-EDENT-C）的信度和效度。

方法

按照国际指南进行翻译和跨文化调适后，招募162名全口义齿佩戴者完成问卷。采用内部一致性和重测法评估OHIP-EDENT-C的信度。通过结构效度和收敛效度分析OHIP-EDENT-C的效度。基于因子分析确定结构效度，通过分析OHIP-EDENT-C分量表得分与整体问题之间的相关性确定收敛效度。

结果

OHIP-EDENT-C总分的Cronbach's alpha值（内部信度）为0.972，组内相关系数值（重测信度）为0.763（与原始OHIP-EDENT相似）。通过因子分析确定结构效度，提取五个因子，占方差的74.31%。所有项目的因子载荷均高于0.40。在收敛效度方面，OHIP-EDENT-C分量表与整体问题显著高度相关。
