Commentary: A homicide-suicide assessment model

In this issue of the Journal, Dr. Paolo Roma and colleagues review international research spanning 60 years and highlight the centrality of psychiatric factors in the phenomenon of homicide-suicide (H-S). This commentary examines several challenges presented by definitional variability and the use of general sources as data. We suggest directions for future research, particularly using the established violence literature, to move toward intervention and management of H-S. We also examine the similarities between H-S and stalking and reflect on the potential for the stalking literature to inform the understanding and management of H-S.
