The tripartite meaning model and suicidal desire
A Multidimensional Examination of Dissociation and Its Relationship With Suicide Ideation and Attempts
Used multiple measures to capture distinct dimensions of dissociation. • Suicide ideation was most strongly linked to Depersonalization and Zoning Out. • Suicide attempts (among ideators) were most strongly linked to Reexperiencing. • Psychological pain and PTSD may partly explain the dissociation–ideation links. • PTSD may explain the association between Reexperiencing and suicide attempts. Dissociation is a multidimensional construct linked to …
Psychache, Hopelessness, and Suicidal Ideation and Behaviors
This study explored the relationship between variables emphasized in the theory's first step of the three-step theory (3ST)-psychache, hopelessness, and their interaction-to suicide-related variables (i.e., lifetime suicidal ideation and attempt, past-year suicidal ideation, communication of suicidal thoughts, and self-reported future suicide attempt likelihood). Chinese undergraduate students ( N = 11,399; mean age = 20.69 ± 1.35) from seven pro…
The psychometric properties and clinical utility of the Norwegian versions of the deliberate self-harm inventory and the inventory of statements about self-injury
Deliberate self-harm (DSH) is a widespread transdiagnostic health problem with increasing prevalence among adolescences, and young adults. It is therefore essential to effectively chart the epidemiology of DSH, as well as to assess the efficacy of interventions designed to modify this behavior. The aim was to translate and analyze the psychometric properties of the Norwegian versions of two instruments designed to assess DSH: the Deliberate Self-…
Identifying suicide ideation in mental health application posts
The growing use of digitized mental health applications requires new reliable early screening tools to identify user suicide risk. We used a lexicon-based random forest machine learning algorithm to predict suicide ideation scores from 714 online community text posts from December 2019 to April 2020. We validated predicted scores against expert-rated suicide ideation scores. The algorithm-predicted scores offered high validity and a low error rat…
Sexual orientation and adolescent suicide attempt and self‐harm
Identifying as a sexual minority was associated with approximately 50% increased odds of SA/SH in adolescence after adjusting for unmeasured genetic and environmental factors shared by twins and for childhood psychopathology. The results support that environmental factors specifically associated with identifying as a sexual minority likely increase risk for SA/SH. Our findings highlight the need to monitor suicidality risk among this group
The role of theory for understanding and preventing suicide (but not predicting it)
Hjelmeland and Knizek suggest that parsimonious theory is inappropriate for explaining a highly complex and contextual phenomenon like suicide. Similar suggestions have been made by others. In this commentary, I counter that the pursuit of parsimonious theory is at the core of any scientific enterprise, including health sciences and suicide science. Using examples from physics and psychology, I illustrate that parsimonious theories have been esse…
Predictors of future suicide attempt among adolescents with suicidal thoughts or non-suicidal self-harm
BACKGROUND: Suicidal thoughts and non-suicidal self-harm are common in adolescents and are strongly associated with suicide attempts. We aimed to identify predictors of future suicide attempts in these high-risk groups. METHODS: Participants were from the Avon Longitudinal Study of Parents and Children, a population-based birth cohort study in the UK. The sample included 456 adolescents who reported suicidal thoughts and 569 who reported non-suic…
Ideation-to-action theories of suicide
Validation of a Brief Version of the Difficulties in Emotion Regulation Scale (Ders-18) in Five Samples
Suicide, Suicide Attempts, and Suicidal Ideation
Suicidal behavior is a leading cause of death and disability worldwide. Fortunately, recent developments in suicide theory and research promise to meaningfully advance knowledge and prevention. One key development is the ideation-to-action framework, which stipulates that (a) the development of suicidal ideation and (b) the progression from ideation to suicide attempts are distinct phenomena with distinct explanations and predictors. A second key…
The Three-Step Theory (3ST)
Nonsuicidal Self-Injury
Differentiating Suicide Attempters from Suicide Ideators
Most individuals who consider suicide do not make suicide attempts. It is therefore critical to identify which suicide ideators are at greatest risk of acting on their thoughts. However, few seminal theories of suicide address which ideators go on to make attempts. In addition, perhaps surprisingly, most oft‐cited risk factors for suicide—such as psychiatric disorders, depression, hopelessness, and even impulsivity—distinguish poorly between thos…
The relationship between nonsuicidal self-injury and attempted suicide
Theoretical and empirical literature suggests that nonsuicidal self-injury (NSSI) may represent a particularly important risk factor for suicide. The present study examined the associations of NSSI and established suicide risk factors to attempted suicide in four samples: adolescent psychiatric patients (n = 139), adolescent high school students (n = 426), university undergraduates (n = 1,364), and a random-digit dialing sample of United States a…
Non-suicidal self-injury in United States adults
Background Non-suicidal self-injury (NSSI) has received increased attention in the mental health literature and has been proposed as a diagnostic entity for DSM-5. However, data on NSSI in the United States adult population are lacking. Method The prevalence and nature of NSSI were examined in a random-digit dialing sample of 439 adults in the United States. Participants were recruited during July and August of 2008. Results Lifetime prevalence o…
Assessing the Functions of Non-suicidal Self-injury
Measurement of emotion dysregulation in adolescents.
The construct of emotion dysregulation increasingly has been used to explain diverse psychopathologies across the lifespan. The Difficulties in Emotion Regulation Scale (DERS; K. L. Gratz & L. Roemer, 2004) represents the most comprehensive measure of the construct to date and exhibits good reliability and validity in adults; however, the measure has yet to be tested in adolescents. The present study examined the psychometric properties of the DE…
Identifying clinically distinct subgroups of self-injurers among young adults
High rates of nonsuicidal self-injury (NSSI; 14%-17%) in adolescents and young adults suggest that some self-injurers may exhibit more or different psychiatric problems than others. In the present study, the authors utilized a latent class analysis to identify clinically distinct subgroups of self-injurers. Participants were 205 young adults with a history of 1 or more NSSI behaviors. Latent classes were identified on the basis of method (e.g., c…
Self‐injury
Non‐suicidal self‐injury is the intentional destruction of body tissue without suicidal intent and for purposes not socially sanctioned. In this practice‐friendly review, the authors summarize the empirical research on who self‐injures, why people self‐injure, and what treatments have demonstrated effectiveness. Self‐injury is more common in adolescents and young adults as compared to adults. Common forms include cutting, severe scratching, burni…

Meta-perception for pathological personality traits
Deliberate Self-Harm in a Nonclinical Population
OBJECTIVE: Research on deliberate self-harm (intentionally injuring oneself without suicidal intent) has focused on clinical and forensic populations. Studying only these populations, which typically have serious psychopathology, may lead to inflated estimates of the association between self-harm and psychiatric disorder, as well as of the prevalence of deliberate self-harm. The present study investigated the prevalence and correlates of delibera…
