Substance use frequency relates to suicidal ideation through perceived burdensomeness and to suicide attempts through capability for suicide

Background Although substance use has been linked to both suicidal ideation and suicide attempts, the factors underlying these relations remain unclear. The Interpersonal-Psychological Theory of Suicide (ITS) provides a framework for understanding how substance use may increase suicide risk. The purpose of the current study was to examine if frequency of substance use is indirectly […]

Perfectionistic self-presentation, socially prescribed perfectionism, self-oriented perfectionism, interpersonal hopelessness, and suicidal ideation in U.S. adults: Reexamining the social disconnection model

Objective Research has linked perfectionism to increased suicidal ideation (SI), although less is known regarding the mechanisms that explain this relation. The Perfectionism Social Disconnection Model (PSDM) posits that interpersonal aspects of perfectionism cause interpersonal problems (e.g., hostility, loneliness) which in turn increase a person’s risk for experiencing SI. The present study aimed to replicate […]

Few do and to few: Disclosure of suicidal thoughts in friendship networks of young adults experiencing homelessness

Disclosure of one’s suicidal thoughts is a pivotal but under-investigated mechanism for preventing suicide among young adults experiencing homelessness (YAEH). In a sample of 527 YAEH, we adopted a multi-level perspective to assess patterns and correlates of disclosure in their friendship networks. Less than one-third of YAEH disclosed their suicidal thoughts—half of them doing so […]

Burden, belonging, and homelessness: Disclosure and social network differences among LGBTQ youth recruited from a suicide crisis service provider

Among LGBTQ youth, suicidality and homelessness occur at heightened rates. Using the Interpersonal Theory of Suicide (ITS), this study seeks to explore the associations of having a parent, family member, friend, or romantic partner in one’s social network and not being “out” to specific network members (lack of disclosure) with ITS constructs (perceived burdensomeness and […]

A content analysis of Reddit users’ perspectives on reasons for not following through with a suicide attempt

Despite a growing understanding of the triggers for suicidal thoughts and behavior, little is known about the mechanisms that prevent people from killing themselves. The goal of the present study was to use publicly available Reddit data to better understand the reasons that people give for not following through with a potentially lethal suicide attempt. […]

Social ties cut both ways: Self-harm and adolescent peer networks

Peers play an important role in adolescence, a time when self-harm arises as a major health risk, but little is known about the social networks of adolescents who cut. Peer network positions can affect mental distress related to cutting or provide direct social motivations for self-harm. This study uses PROSPER survey data from U.S. high […]

Physical, mental, and social wellbeing and their association with death by suicide and self-harm in older adults: A community-based cohort study

Compensatory social networking site use, family support, and depression among college freshman: Three-wave panel study

Background: Freshmen were found to use social networking sites (SNS) as a useful medium to effectively adjust to college life, which hints at a tendency to resort to SNS for social compensation. However, the compensatory use of SNS is usually problematic. Objective: This study explores why a subgroup of freshmen developed depressive symptoms while socially […]

Cross-level sociodemographic homogeneity alters individual risk for completed suicide

Among deaths of despair, the individual and community correlates of US suicides have been consistently identified and are well known. However, the suicide rate has been stubbornly unyielding to reduction efforts, promoting calls for novel research directions. Linking levels of influence has been proposed in theory but blocked by data limitations in the United States. […]

Deep neural networks detect suicide risk from textual Facebook posts

Background: Detection of suicide risk is a highly prioritized, yet complicated task. In fact, five decades of suicide research produced predictions that were only marginally better than chance (AUCs = 0.56 – 0.58). Advanced machine learning methods open up new opportunities for progress in mental health research. In the present study, Artificial Neural Network (ANN) […]

Detection of suicidal intent in Spanish language social networks using machine learning

Peer-adult network structure and suicide attempts in 38 high schools: Implications for network-informed suicide prevention

Background Strengthening social integration could prevent suicidal behavior. However, minimal research has examined social integration through relationship network structure. To address this important gap, we tested whether structural characteristics of school networks predict school rates of ideation and attempts. Methods In 38 US high schools, 10,291 students nominated close friends and trusted adults to construct […]

Robust peer-monitoring on graphs with an application to suicide prevention in social net

We consider the problem of selecting a subset of nodes (individuals) in a (social) network that can act as monitors capable of “watching-out” for their neighbors (friends) when the availability or performance of the chosen monitors is uncertain. Such problems arise for example in the context of “Gatekeeper Trainings” for suicide prevention. We formulate this […]
