Every day situations arising in health care contain ethical issues influencing care providers' conscience. How and to what extent conscience is influenced may differ according to how conscience is perceived. This study aimed to explore the relationship between perceptions of conscience and stress of conscience among care providers working in municipal housing for elderly people. A total of 166 care providers were approached, of which 146 (50 registered nurses and 96 nurses' aides/enrolled nurses) completed a questionnaire containing the Perceptions of Conscience Questionnaire and the Stress of Conscience Questionnaire. A multivariate canonical correlation analysis was conducted. The first two functions emerging from the analysis themselves explained a noteworthy amount of the shared variance (25.6% and 17.8%). These two dimensions of the relationship were interpreted either as having to deaden one's conscience relating to external demands in order to be able to collaborate with coworkers, or as having to deaden one's conscience relating to internal demands in order to uphold one's identity as a `good' health care professional.
