There is a wide variety in the responses of doctors towards requests for palliative care and/or euthanasia. To evaluate these requests, most doctors have to rely on their personal experiences. We presume that their decisions about EOL-interventions are not only founded on medical experience and patient-linked-criteria, but also on personal opinions and philosophy-of-life. This paper is part of a broader project on religion and ethics at the EOL. Very few investigations have been made yet on this issue and, when done so, the topics exploring religiosity are mostly very superficial. Our research investigates the influence of the religious attitudes of GP’s towards their attitude on palliative care and euthanasia. A mailed questionnaire, based on quantitative operationalisations of the theories of Wulff and Kohlberg, is used for two groups of Flemish GP’s: a random sample of local GP’s and a sample of GP’s who followed a palliative care course. The questionnaire consists of 3 parts. The religious attitude is mapped by the Post-Critical Belief Scale (PCB). The PCB-scale, developed by Hutsebaut, has proven to be a reliable instrument to be used in a fully secularised society like Belgium. The Moral Judgement Test (MJT), developed by Lind, is used to measure ethical maturity and moral competence. The MJTexplores reactions towards suggested solutions for ethical dilemma’s. Opinions on matters of dying, death, palliative care and euthanasia are mapped by response to an inventory of statements. Different religious attitudes are expected to correlate with different responses towards requests for palliative care and/ or euthanasia. Detailed analysis of the used instruments and preliminary results will be presented on the research-forum.
