Up to 20% of individuals around the globe will suffer from depression in their lifetime; however, strategies to minimize risk and rapid treatments are not available for all affected individuals. Depression is a significant public health concern that impacts social and occupational functioning, and is also a major risk factor for suicide. Suicidal ideation and behaviour, for example, are often increased in individuals suffering from depression. Importantly, however, suicides are preventable when warning signs are recognized early, and timely, evidence-based interventions are implemented. The most successful efforts to prevent suicides are likely to be multipronged approaches that target different facets of experience to support at-risk individuals. This Collection welcomes original research articles that expand our understanding of depression and suicidality, which may or may not co-occur with depression. Studies reporting empirical research on the risk factors, warning signs, and strategies aimed at the prevention of suicide that may lead to policy recommendations are of particular interest.
