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.

The World Health Organisation Quality of Life (WHOQOL) questionnaires are widely used around the world and can claim strong cross-cultural validity due to their development in collaboration with international field centres. To enhance conceptual equivalence of quality of life across cultures, optional national items are often developed for use alongside the core instrument. The present study outlines the development of national items for the New Zealand WHOQOL-BREF. Focus groups with members of the community as well as health experts discussed what constitutes quality of life in their opinion. Based on themes extracted of aspects not contained in the existing WHOQOL instrument, 46 candidate items were generated and subsequently rated for their importance by a random sample of 585 individuals from the general population. Applying importance criteria reduced these items to 24, which were then sent to another large random sample (n = 808) to be rated alongside the existing WHOQOL-BREF. A final set of five items met the criteria for national items. Confirmatory factor analysis identified four national items as belonging to the psychological domain of quality of life, and one item to the social domain. Rasch analysis validated these results and generated ordinal-to-interval conversion algorithms to allow use of parametric statistics for domain scores with and without national items.

Previous research links religion/spirituality to beneficial health outcomes, but the majority of these studies used samples from populations with long-term illness or older people. The present study explored whether the links between religion/ spirituality and quality of life can be observed in a sample of younger adults, and also whether religion/spirituality could function as a coping mechanism in international tertiary students who are often subjected to significant stressors related to acculturation and being away from their families. The sample consisted of 218 domestic and 164 international students at a New Zealand university who were given the quality of life inventory and the additional special module about spirituality/religion/personal beliefs, both developed by the World Health Organization in collaboration with many member states. Religion/spirituality was significantly correlated with psychological quality of life in both groups, and social quality of life in international students. The results also show that religion/ spirituality might function as a coping mechanism in international students in response to stressors of acculturation.

Objective: When the World Health Organization Quality of Life tools were developed by 15 collaborating centres in 14 countries, respondents rated how important they considered various facets of health-related quality of life. The present study compared quality of life importance ratings from New Zealanders with the global data collected 17 years earlier. Possible differences by gender and age were also explored. Methods:A WHOQOL importance questionnaire was posted to a random sample of 2,000 New Zealanders. The ratings from the 585 questionnaires that were returned were ranked in order of importance and compared with the rankings from the original WHOQOL work. Results:The overall pattern of rankings of importance items was strikingly similar to that of the global data. Some of the few differences included comparatively lower importance ratings by New Zealanders of the facet to be able to work and higher ratings of feeling physically safe and secure. Other differences in importance ratings were also noted by gender and age group. Conclusions:The overall high similarities of importance rankings with the global dataset suggest that the cross-cultural validity of the instrument may still be current. The few observed differences could reflect aspects unique to New Zealand or the presence of global trends during the 17 years since the original WHOQOL work, highlighting the utility of periodic investigations into the need to update the instrument.
