Suicide prevention strategies: An overview of current evidence and best practice elements

Abstract

Suicide is a complex human behavior with multiple interacting determinants. Clinicians and practitioners often face difficulties in assimilating the evidence base for suicide prevention interventions, evaluating their effectiveness and decoding the best practice elements of each approach. In this article, we do not aim to provide an exhaustive coverage of every approach. Instead, we provide an overview of the following eight major suicide prevention interventions: awareness programs, screening, gatekeeper training, access to means restriction, follow-up care, hotlines, media strategies, pharmacotherapeutic and psychotherapeutic approaches. The evidence base and components of each approach are described to facilitate replication. The best practice elements are synthesized from each approach and presented to aid program development and practice. Although a number of approaches hold promise, there are difficulties in ascertaining the effective elements under each of them. Innovative research designs are needed to address this knowledge gap as it will facilitate optimal allocation of resources for suicide prevention.
