Responding to suicide clusters in the community: What do existing suicide cluster response frameworks recommend and how are they implemented?

Suicide clusters involve an excessive number of suicides, suicide attempts, or both, that occur close in space or time or involve social links between cluster members. Although suicide clusters are rare, evidence documenting the implementation of suicide cluster response activities in communities is required yet remains limited. In this study, we identified the core components […]

Clusters of suicidal events among young people: Do clusters from one time period predict later clusters?

We sought to compare clusters of suicidal events between two different time periods and examine the extent to which earlier clusters predict later clusters. We included data on suicides and suicide attempts from New South Wales between July 2001 and June 2012 and Western Australia between January 2000 and December 2011. Suicide attempts included admissions […]

Does the media matter to suicide?: Examining the social dynamics surrounding media reporting on suicide in a suicide-prone community

Despite the widespread acknowledgement by public health organizations that media reporting matters to suicide, this link has been much debated and the mechanisms undergirding it poorly understood. With this study, I combine a media analysis with ethnographic data collected during 2014–2016 (N = 91) to examine the social dynamicssurrounding media reporting on suicide in a community (that I call Poplar Grove, USA) with an […]
