Daily impulsivity: Associations with suicidal ideation in unipolar depressive psychiatric inpatients

Recent studies suggest that impulsivity fluctuates over time. It is unclear if state-impulsivity serves as a risk factor of suicidal ideation (SI) at a state level. A sample of 74 psychiatric inpatients with depression (M = 37.6 years, 72% female) and SI completed baseline measurements and an ecological momentary assessment over a 6-day period. Despite […]

Impulsivity and impulsivity-related endophenotypes in suicidal patients with substance use disorders: An exploratory study

Suicidal behavior (SB) is a major problem in patients with substance use disorders (SUDs). However, little is known about specific SB risk factors in this population, and pathogenetic hypotheses are difficult to disentangle. This study investigated some SB and SUD-related endophenotypes, such as impulsivity, aggression, trait anger, and risk-taking behaviors (RTBs), in forty-eight patients with […]

Childhood trauma and the severity of past suicide attempts in outpatients with cocaine use disorders

Suicide attempts have been associated with both cocaine use disorder (CocUD) and childhood trauma. We investigated how childhood trauma is an independent risk factor for serious and recurrent suicide attempts in CocUD. Method: 298 outpatients (23% women) with CocUD underwent standardized assessments of substance dependence (Diagnostic and Statistical Manual—mental disorders, fourth edition, text revised), impulsiveness, […]

Lipid profile and impulsivity in suicidal patients with major depressive disorder

Introduction Previous observational cohort studies showed an association between low serum lipid levels and suicide. This study was undertaken to examine the relationship between lipid parameters and impulsivity in suicidal patients with major depressive disorder (MDD). Methods The current study included 100 patients with MDD distributed as 50 patients with recent suicidal attempts and 50 […]

Resilience and vulnerability factors influence the cortisol awakening response in individuals vulnerable to suicide

Suicide is a global health issue. Dysregulated hypothalamic-pituitary-adrenal (HPA) axis activity, as measured by cortisol levels, has been identified as one potential risk factor. Evidence is emerging to suggest that different psychological factors may be associated with increased resilience and vulnerability in this context. The current study investigated whether trait resilience, social support, socially prescribed […]

Relationship between suicide attempt history and borderline personality disorder, aggression, impulsivity, and self-mutilative behavior among male inpatients with substance use disorder

Objective: The purpose of this study was to evaluate the relationship between lifetime history of suicide attempt (HSA) and borderline personality disorder (BPD), aggression, impulsivity, and selfmutilative behavior (SMB) in a sample of male inpatients with substance use disorder (SUD). Method: The sample included 132 male inpatients with alcohol or opioid use disorder. The participants […]

Impulsiveness and suicide in male offenders: Examining the buffer roles of regulatory emotional self-efficacy and flourishing

Objectives: Although impulsiveness has been recognized as a risk factor for suicide, few studies have explored how to protect offenders with impulsiveness from the risk of suicide. This study aims to examine the relationships among impulsiveness, suicide risk, regulatory emotional self-efficacy (RESE), and flourishing, focusing on the moderating effects of RESE and flourishing in the relationship […]

The serious suicide attempts approach for understanding suicide: Review of the psychological evidence

The study of survivors of a serious suicide attempt (SSA)––an attempt that would have been fatal had it not been for the provision of rapid and effective emergency treatment––can help researchers understand the suicidal mind. Serious suicide attempters are epidemiologically very similar to those who died by suicide, and thus can serve as valid proxies for studying […]

Impulsivity, hostility and suicidality in patients diagnosed with obsessive compulsive disorder

Background: There are limited data on suicidal behaviour in obsessive-compulsive disorder (OCD). This study aimed to evaluate several aspects affecting suicidality in OCD patients and determine whether impulsivity or hostility are associated with suicide attempts in this vulnerable group. Methods: Eighty-one patients with OCD were assessed by structured clinical interview for DSM-IV (SCID I), Yale-Brown Obsessive–Compulsive Scale […]

Direct and indirect effects of behavioral inhibition / activation systems on depression and current suicidal ideation through rumination and self-reflection

This study aimed to evaluate direct and indirect effects of the behavioral inhibition system (BIS) and the behavioral activation system (BAS) on depression and current suicidal ideation through rumination and self-reflection in a sample of suicide attempters. Three hundred suicide attempters completed the Rumination/Reflection Questionnaire (RRQ), the Carver and White BIS/BAS scales, the Beck Scale […]

Prevalence and risk-markers of self-harm in autistic children and adults

Self-harm is purportedly common in autistic individuals, but under-researched, particularly in younger samples and those without intellectual disability. This study aimed to describe prevalence, profile and correlates of self-harm in autistic individuals without impairments in adaptive functioning. Parents of autistic participants (n = 83) completed questionnaires regarding the presence/topography of self-harm, demographic characteristics, autism severity, age of diagnosis, affect, activity […]

From urges to action: Negative urgency and nonsuicidal self-injury in an acute transdiagnostic sample

Urgency–rash action during strong emotion–is a robust correlate of nonsuicidal self-injury (NSSI). This study tested whether urgency is associated with time between NSSI urges and NSSI, and sought to replicate the finding that urgency is associated with NSSI history. Participants attending a partial hospitalization program (N = 669) completed self-report measures of urgency, NSSI history and latency, […]

Impulsivity and cognitive flexibility as neuropsychological markers for suicidality: A multi-modal investigation among military veterans with alcohol use disorder and PTSD

To examine relations between self-report and behavioral measures of impulsivity and cognitive flexibility with suicidal ideation and self-harm and suicide attempt history. Methods: Eighty-seven military veterans who met DSM-5 diagnostic criteria for alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD) were evaluated for current suicidal ideation and self-harm, suicide attempt history, impulsivity, and cognitive […]

Evaluation of BDNF as a biomarker for impulsivity in a psychiatric population

Impulsivity is an important risk factor for suicide and therefore, identifying biomarkers associated with impulsivity could be important in evaluating psychiatric patients. Currently, assessment of impulsivity is based solely on clinical evaluation. In this study, brain-derived neurotrophic factor (BDNF), a nerve growth factor, was evaluated as a potential biomarker for impulsivity. We hypothesize that elevated […]

Exploratory analysis of behavioural impulsivity, pro-inflammatory cytokines, and resting-state frontal EEG activity associated with non-suicidal self-injury in patients with mood disorder

Introduction: Non-suicidal self-injury (NSSI) is a rapidly increasing mental health problem that requires more clinical attention. In this study, we aimed to explore the biobehavioral markers of NSSI in participants with mood disorders. Methods: A total of 45 participants with mood disorders (bipolar I, II, and major depressive disorder) were included in the study. Behavioral […]

Neurobiological elements of hopelessness and impulsivity in suicidal behavior

Suicide is an important public health problem. Besides the well-known psychosocial factors that contribute to suicidal behavior, the neurobiological factors have gained much visibility in the last years. The neurobiological studies in suicide were linked with psychiatric disorders or they were considered in an independent way. The emphasis on the biological aspects of suicide has […]

The association of trait impulsivity and suicidal ideation and its fluctuation in the context of the Interpersonal Theory of Suicide

Background Although the relationship of trait impulsivity and suicidal behavior is well established, its relationship with suicidal ideation and its fluctuation still remains unclear. Our aim is to examine (1) the relationship of trait impulsivity and suicidal ideation and behavior in the context of the Interpersonal Psychological Theory of Suicide (IPTS) and (2) the association […]

Contribution of genes and environment to the longitudinal association between childhood impulsive-aggression and suicidality in adolescence

Background Population‐based and family studies showed that impulsive‐aggression predicts suicidality; however, the underlying etiological nature of this association is poorly understood. The objective was to determine the contribution of genes and environment to the association between childhood impulsive‐aggression and serious suicidal ideation/attempt in young adulthood. Methods N = 862 twins (435 families) from the Quebec Newborn Twin […]

Impulsivity, painful and provocative events, and suicide intent: Testing the Interpersonal Theory of Suicide

Objective The Interpersonal Theory of Suicide (IPTS; Joiner, 2005. Why People Die by Suicide. Cambridge, MA: Harvard University Press) hypothesizes that repeated exposure to painful and provocative events (PPE) increases capability for suicide (CS), therefore facilitating the development of suicidal intent, and that impulsive individuals are more likely to experience these painful and provocative events, creating […]

Insomnia symptoms predict emotional dysregulation, impulsivity and suicidality in depressive bipolar II patients with mixed features

Introduction Insomnia symptoms are very common in Bipolar Disorder. Our aim was to assess the potential association between insomnia, emotion dysregulation and suicidality in subjects with Bipolar Disorder. Methods Seventy-seven subjects with Bipolar Disorder type II with a depressive episode with mixed features were recruited. Patients were assessed with SCID-DSM-5, the Insomnia Severity Index (ISI), the Difficulties in Emotion Regulation Scale (DERS), the Scale […]

Problematic smartphone use associated with greater alcohol consumption, mental health issues, poorer academic performance, and impulsivity

Background This study sought to examine the occurrence of the problematic use of smartphones in a university sample and associated physical and mental health correlates, including potential relationships with risky sexual practices. Methods A 156-item anonymous online survey was distributed via e-mail to a sample of 9,449 university students. In addition to problematic smartphone usage, […]

Frequency of nonsuicidal self-injury is associated with impulsive decision-making during criticism

Research indicates that nonsuicidal self-injury (NSSI) is associated with impulsive traits, but not impulsive behavior on laboratory tasks, even in the context of negative mood. However, previous studies may not have induced forms of negative affect most relevant to NSSI. For example, evidence implicates both self-criticism and feeling criticized by others in NSSI engagement. We […]

Differences between impulsive and non-impulsive suicide attempts among individuals treated in emergency rooms of South Korea

OBJECTIVE: A considerable proportion of suicide attempts are the result of sudden desires. Understanding such impulsive suicide attempts is necessary for effective interventions. We evaluated the impulsivity of suicide attempters treated in emergency rooms. The aim of the study was to identify the characteristics of impulsive suicide attempts by comparing these individuals to those who […]
