Semi-structured interviews were performed with 12 psychiatrists regarding their perceptions of the Swedish Vision Zero for Suicide. Focusing on the topic of rational suicide, we re-analyzed these interviews using descriptive content analysis. The informants generally acknowledged the existence of rational suicide and its occurrence also among severely ill psychiatric patients, but expressed varying perceptions of the relevance of the concept in clinical practice. The difficulty of identifying rational suicide was considered to be a major problem. Another experience was a potential conflict between promoting a patient's rationality and preventing suicide. While the normative aspects of rational suicide have been addressed in the literature, our results highlight a need for further attention to the epistemological and practical aspects of rational suicide.
