Suicidal ideation and risky behavior are related through impulsivity and low wish to live

Objective: Numerous studies have found support for the relationship between suicide and risky behavior. However, few studies have examined factors that may help explain the relationship between suicidal ideation (SI) and risky behavior. This preregistered study examined the relationship between SI and risky behavior and whether there is an indirect relationship through hopelessness, impulsivity, and low […]

Longitudinal associations between executive function impairments and suicide risk in patients with major depressive disorder: A 1-year follow-up study

Impaired executive function (EF) is a key feature of patients with major depressive disorder (MDD) that several studies have linked to suicidal ideation and suicide attempts. This is the first longitudinal study to examine the association between impaired EF and suicide risk in adult patients with MDD. Longitudinal prospective study with 3 assessment points: baseline, […]

The relationships between risk-taking, depression, and alcohol use in the experience of suicidal ideation among adults in the general population

Risk-taking is associated with suicide among depressed adolescents. In the United States, alcohol is among the most used substances resulting in need for treatment. While alcohol use relates to greater depression and suicidality, less is known about these relationships with risk-taking tendencies, particularly among adult populations. The current study examined suicidal ideation, alcohol use, depression, […]

Meaning in life moderates relations between personality and temperament and nonsuicidal self-injury in hospitalized adolescents

Previous research indicates that sensation seeking, emotion dysregulation, and impulsivity are predictive of non-suicidal self-injury (NSSI). A body of research supports that meaning in life predicts improved mental health and well-being, including fewer suicidal thoughts and attempts, yet no research has examined the moderating effects of meaning in life on the relations between personality and […]

Effects of the sex ratio and socioeconomic deprivation on male mortality

We explored relationships between male mortality and the sex ratio. (We tested relationships across 142 societies and in longitudinal data from Scotland. A male-biased sex ratio was associated with reduced mortality by intentional self-harm across 142 societies. This was replicated in longitudinal Scottish data, and men were less likely to die by suicide and assault […]

Decision-making and cognitive control in adolescent suicidal behaviors: A qualitative systematic review of the literature

Suicide and suicidal behaviors represent a leading cause of morbidity and mortality during adolescence. While several lines of evidence suggest that suicidal behaviors are associated with risky decisions and deficient cognitive control in laboratory tasks in adults, comparatively less is known about adolescents. Here, we systematically reviewed the literature on the association between these neurocognitive […]

Effects of bupropion (wellbutrin) on suicidal behavior, risk taking behavior, and mood

This study analyzed the effects that the well known antidepressant Wellbutrin (Bupropion) has on risk taking behavior, suicidal behavior, social behavior, and motivation. Despite Bupropion’s ability to improve motivation it has been associated with numerous suicides. There have been reports that state that Bupropion is the worst antidepressant for treating suicidal behaviors and may even […]

OBJECTIVES: The aim of this paper was to identify the opinions of adolescents aged 16-19, attending public high schools in Warsaw, on the risk factors of suicide. METHODS: The study group consisted of adolescents who were aged 16-19 in the year 2015 (M = 17.29; SD = 0.94). The respondents attended eight public high schools […]

Peer victimization and suicidal thoughts and behaviors in depressed adolescents.

Suicide is a leading cause of death among youth worldwide, and depressed adolescents are at a significantly elevated risk to report suicidal ideation, planning, and attempts. Peer victimization is a robust predictor of adolescent suicidal thoughts and behaviors (STBs), but little research has focused on why bullying leads to suicidal thoughts and behaviors. To address […]

Suicide risk behaviors among sexual minority adolescents in the United States, 2015.

Sexual minority (lesbian, gay, bisexual, or questioning) adolescents are believed to have elevated suicide risks.1Studies supporting this claim, however, rarely use nationally representative samples, which is a major limitation given that stigma and prevention resources vary across communities and may influence suicide risk behaviors.2When nationally representative studies are available, they are not recent.3 Moreover, studies have […]

The role of positive expectancies in risk behavior: an exploration of alcohol use and nonsuicidal self-injury.

Abstract. Background: Alcohol use and nonsuicidal self-injury (NSSI) appear to share a conceptual overlap in functions (e.g., tension reduction). Alcohol use has been identified as a risk factor for NSSI, and higher rates of alcohol use have been documented among those with NSSI history. Aims: This study examined whether NSSI-related alcohol expectancies affect relations between […]

Suicide ideation and attempts among adolescents engaged in risk behaviors: A latent class analysis.

This study addressed gaps in the literature regarding how different profiles of adolescent risk behavior relate to suicide. Data came from the 2010 Minnesota Student Survey of 9th and 12th grade students. Latent class analysis derived a set of four classes reflecting unique patterns of eight behaviors: maladaptive dieting, prescription drug misuse, illegal drug use, […]

Psychiatric disorders, suicidal ideation, and sexually transmitted infections among post-deployment veterans who utilize digital social media for sexual partner seeking.

Highlights Use of digital social media to find sexual partners (DSMSP +) is common among veterans. •DSMSP + is associated with PTSD, insomnia, depression and suicidality. •DSMSP + is associated with hypersexuality and sexually transmitted infections.

British outcomes following self-inflicted poisoning during pregnancy, California, 2000 to 2004.

There were 430 hospital discharges for an intentional poisoning during pregnancy documented in the dataset. Intentional acute poisoning during pregnancy was associated with several adverse birth outcomes; however, these relationships may be confounded by concomitant maternal substance abuse.

Sensation seeking as a potential screening tool for suicidality in adolescence.

Although suicide could be an adverse health problem related to sensation seeking, this relationship has not been rigorously evaluated. The purpose of this study was to evaluate the relationship between sensation seeking and suicidality (suicidal ideation and plan) among adolescents and to test the influence of depressive symptom on this relationship. Sensation seeking can contribute […]

Suicide by motor vehicle “accident’ in Queensland.

Around the world, a substantial proportion of motor vehicle crash deaths are recognized as ÒhiddenÓ suicides. This project sought to progress understandings of drivers who used a motor vehicle to die by suicide in Queensland, Australia, during the period 1990 to 2007. Analysis focused on life circumstances and events preceding the death, physical and mental […]

Risk-sensitive decision-making deficit in adolescent suicide attempters.

Decision-making deficits may play an important role in vulnerability to suicidal behavior, but few studies have examined decision-making performance in youth at risk for suicide. In this study, we seek to extend recent findings that adolescent suicide attempters process risk evaluations differently than adolescents who have not attempted suicide. Adolescents with a history of suicide […]

Race, urban context, and Russian roulette: findings from the National Violent Death Reporting system, 2003-2006.

Previous work on Russian roulette has focused on data from large cities. It is unclear if the epidemiological patterns based on large cities will replicate for the nation as a whole, and if the influence of minority status will be moderated by urban context. The present investigation fills these gaps by providing descriptive epidemiological data […]
