This handbook summarises the experience gathered in Austria between 2012 and 2022 with implementing the national suicide prevention programme SUPRA. Its aim is to provide guid-ance to other countries, partners of the Joint Action ImpleMENTAL work package 6, for de-veloping or scaling up a suicide prevention strategy at national/regional level. It introduces the WHO-framework (based on various WHO-reports) and illustrates how it served as a key reference and provided crucial guidance for Austria. Lessons learned in Aus-tria are shared, based not only on the experience of implementing SUPRA, but also on the experience of implementing other national strategies (related to topics other than suicide prevention).
