Despite the fact that many studies report these correlates, the available treatment studies, which merely comprise evaluations of general treatment interventions, often without a randomised controlled design, have not incorporated knowledge about risk factors (Hawton et al., 1998). In addition, existing explanatory and treatment models do not address the heterogeneity of the group of DSH patients. This is surprising, considering the variety of characteristics and problems of DSH patients. So far, most models focus on single psychiatric problems, such as depression or anxiety disorders.
