The aim of this study was to identify the characteristics present in the consultation text of individuals at high risk of suicide in a text-based crisis intervention project for suicide prevention. We analyzed data, including online questionnaire responses and consultation text content, from 519 individuals (69.7% of whom were women and 62.8% of whom were under 20) consulted in the Internet Gatekeeper project. Results from correspondence analysis and a comparison of co-occurrence network diagrams indicated that the consultation text of individuals at high risk of suicide often includes references to suicide, death, and suicide methods, references to being a burden to others such as family members and parents, and references to self-hatred. However, there were relatively few references to communication with those around them. By focusing on these key points, it may be possible to more effectively monitor the extent to which the target population of the consultation service includes individuals at high risk of suicide.

This study aimed to summarize the available evidence on educational programs for the nursing of patients who have attempted suicide, and to examine the practice of such educational programs in Japan. The PubMed and Ichushi databases were searched using the keywords “suicide nursing education program.” A total of 14 interventional studies involving nurses were analyzed. The studies were conducted worldwide, most often in hospitals with multiple clinical departments. The educational programs consisted mainly of lectures conducted primarily face-to-face. The content of the educational programs included general knowledge on suicide and skills for working with patients who have attempted suicide. All studies showed that nurses benefited from the educational programs, with improved knowledge and attitude about suicide, and greater confidence in caring for those who have attempted suicide. Thus, it is important to develop educational programs on the nursing of patients who have attempted suicide in Japan.
