Self harm in the absence of expressed suicidal intent is an under explored area in psychiatric nursing research. This paper reports on findings of a study undertaken in two acute psychiatric inpatient units in Ireland. The purpose of the study was to gain an understanding of the practices of psychiatric nurses in relation to people who self harm, but who are not considered suicidal. Semi structured interviews were held with eight psychiatric nurses. Content analysis revealed several themes. For the purpose of this paper the prevention and intervention strategies psychiatric nurses engage in when working with non-suicidal self harming individuals are presented. Recommendations for further research are offered.
