The NERSH Questionnaire and Pool of Data from 12 Countries: Development and Description.

Modern healthcare research has only in recent years investigated the impact of health care workers' religious and other values on medical practice, interaction with patients, and ethically complex decision making. So far, only limited international data exist on the way such values vary across different countries. We therefore established the NERSH International Collaboration on Values in Medicine with datasets on physician religious characteristics and values based on the same questionnaire. The present article provides (a) an overview of the development of the original and optimized questionnaire, (b) an overview of the content of the NERSH data pool at this stage and (c) a brief review of insights gained from articles published with the questionnaire. The pool at this stage consists of data from 17 studies from research units in 12 different countries representing six continents with responses from more than 6000 health professionals. The joint data pool suggests that there are large differences in religious and other moral values across nations and cultures, and that these values contribute to the observed differences in health professionals' clinical practices-across nations and cultures!
