It is common knowledge that words matter. Suicide and self-injury mortality are synonymous in the vital statistics, in contrast to suicide attempts and self-injury morbidity, where the latter also encompasses nonsuicidal self-injury. This false equivalence in mortality dilutes and greatly confounds societal perception of the scope and the nature of the major mental health crisis afflicting our nation. The overlapping suicide and poisoning mortality epidemics really represent a single self-injury mortality (SIM) epidemic. I welcome this opportunity to elucidate my perspective on SIM.
