When forced treatment in mental health care is under consideration, two approaches guide clinicians in their actions: the dominant rights-based approach and the relational ethical approach. We hypothesized that nurses with bachelor's degrees differentiate better between the two approaches than nurses without a degree. To test this hypothesis a survey was performed in major Slovenian health institutions. We found that nurses emphasize the importance of ethics and personal values, but 55.4% of all the nurse participants confused the two approaches. The (...) results confirmed our hypothesis and indicate the importance of nurses' formal education, especially when caring for patients with mental illness. (shrink)
