PURPOSE
The present study validated the abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire for general use in New Zealand.
METHODS
A random postal sample from the national electoral roll was used, and 808 questionnaires were returned. Psychometric properties of the instrument were assessed, including tests of the four-domain factor structure using confirmatory factor analysis and Rasch analysis.
RESULTS
Goodness-of-fit from the confirmatory factor analysis were good, and the overall conclusion of the Rasch analysis supported the confirmatory factor analysis (CFA) findings after dealing with problems of threshold ordering, local dependency, and differential item functioning (DIF).
CONCLUSIONS
The WHOQOL-BREF is valid for general use in New Zealand. In the future work, the WHOQOL-BREF domain scores should either be analyzed using non-parametric statistics or data should be fitted to the Rasch model to derive interval person estimates.
目的
本研究旨在验证世界卫生组织生活质量（WHOQOL-BREF）问卷的简版在新西兰的普遍适用性。
方法
采用全国选举名册的随机邮寄抽样方法，共回收 808 份问卷。对该工具的心理测量学特性进行了评估，包括使用验证性因子分析和 Rasch 分析对四领域因子结构的测试。
结果
验证性因子分析的拟合优度良好，Rasch 分析的总体结论支持验证性因子分析（CFA）的发现，同时也解决了阈值排序、局部依赖和差异项目功能（DIF）的问题。
结论
WHOQOL-BREF 可在新西兰普遍使用。未来的工作中，应该使用非参数统计方法分析 WHOQOL-BREF 领域得分，或者根据 Rasch 模型拟合数据，以获得区间个体估计值。
