Fluctuations in and associations between physical and psychological distance to suicide methods, fearlessness about death, and suicidal intent

Previous evidence has highlighted the potential roles of both physical and psychological distance to suicide methods as an important factor in conferring suicide risk; however, less is known about the temporal stability of and associations between these constructs, other facets of capability for suicide, and suicide-related outcomes. The present study examined fluctuations in and associations […]

Prevention of suicidal behavior

More than 800 000 people die every year from suicide, and about 20 times more attempt suicide. In most countries, suicide risk is highest in older males, and risk of attempted suicide is highest in younger females. The higher lethal level of suicidal acts in males is explained by the preference for more lethal methods, […]

Sociodemographic variables most associated with suicidal behaviour and suicide methods in Europe and America: A systematic review

This Systematic Review is thought to deepen the relation between sociodemographic variables most associated with suicidal behaviour and suicide methods in Europe and America. A research was made from articles and reviews published between 2005-2015 in PsycINFO, Medline, Web of Science Core Collection, Scopus, and SciELO. Thanks to it, we retrieved 5,222 records which were […]

Reducing suicide without affecting underlying mental health: Theoretical underpinnings and a review of the evidence base linking the availability of lethal means and suicide (IN: The International Handbook of Suicide Prevention, 2nd ed., edited by R. C. O’Connor & J. Pirkis)

This chapter provides a synthesis of the empirical literature that assesses the relationship between ready access to highly lethal means of suicide and overall suicide rates. It lays out the theoretical underpinnings of the assertion that reducing access to lethal means of suicide can reduce suicide rates. The most convincing evidence that restricting access to […]

Three leading suicide methods in the United States, 2017–2019: Associations with decedents’ demographic and clinical characteristics

Background and aims: The U.S. suicide data show that use of lethal methods, specifically firearms and hanging/suffocation, has been increasing among young and middle-aged adults of both sexes over the past decades. In this study, we examined demographic and clinical correlates of use of firearms, hanging/suffocation, and poisoning as suicide methods among suicide decedents age 18+. […]

Method-specific suicide rates and accessibility of means: A small-area analysis in Taipei City, Taiwan

Background: Few studies have investigated whether means accessibility is related to the spatial distribution of suicide. Aims: To examine the hypothesis that indicators of the accessibility to specific suicide methods were associated with method-specific suicide rates in Taipei City, Taiwan. Method: Smoothed standardized mortality ratios for method-specific suicide rates across 432 neighborhoods and their associations with means accessibility indicators were estimated using […]

Circumstances surrounding fire-related suicides, 2011 to 2020

Fatal fires are tragic events that are devastating to individuals, families, and communities. From 2011 to 2020, there were on average 220 fire-related deaths in Canada each year. While the majority of fire-related deaths were classified as unintentional, 1 in 6 were classified as intentional (i.e., suicide or homicide). Unlike unintentional fire-related deaths, intentional fire-related deaths result from an individual creating fire with intent […]

Sexual orientation differences in lethal methods used in suicide: Findings from the National Violent Death Reporting System

Overall, most sexual minorities (i.e., lesbians, gay men, bisexuals) identified in the dataset used hanging (38%) followed by firearm (30%) and drug or poison ingestion (20%). Sexual minorities were […]

‘‘If I had access to a gun, I think I would have used it instead’’: Motivations for method choice among sexual and gender minority adults who made a recent near-fatal suicide attempt

Purpose: We examined motivations for suicide attempt method choice among sexual and/or gender minority (SGM) adults who attempted suicide in the previous 18 months. Methods: Individual semistructured interviews (N = 22) explored participants’ motivations.

Searching online for methods of suicide: A content analysis of Danish and English-language websites describing methods of suicide

Background: Information on methods of suicide is available online, and access to information on methods of suicide appears to contribute to a small but significant proportion of suicides. There is limited documentation of how methods of suicide are being profiled, as well as what content exists in other languages than English. Aim: We aimed to analyze and compare […]

Assessment of the lethality of suicide attempts is a neglected topic in the literature in this area. Based on the hypothesis that suicide attempters who choose a highly lethal method differ from those who use less lethal methods, we analyzed the characteristics of suicide attempters who used different suicide methods to determine demographic and clinical […]

“In the moment I wanted to kill myself, and then after I didn’t”: A qualitative investigation of suicide planning, method choice, and method substitution among adolescents hospitalized following a suicide attempt

Research on planning, method choice, and method substitution in adolescents’ suicide attempts is limited. We conducted in-depth interviews with 20 adolescents following their suicide attempt to learn the extent to which the attempt was planned, why they used the method they did, and whether they would have substituted another method if the one they used […]
