Background: The presence of psychiatric disorders is widely recognized as one of the primary risk factors for suicide. A significant proportion of individuals receiving outpatient psychiatric treatment exhibit varying degrees of suicidal behaviors, which may range from mild suicidal ideations to overt suicide attempts. This study aims to elucidate the transdiagnostic symptom dimensions and associated suicidal […]

Suicide is a major societal problem. In Australia, there were 3,144 deaths by suicide in 2021 with suicide being the leading cause of death amongst young people (18-24 years).1 The impact of suicides is particularly devastating for families, friends and communities when they occur in clusters. A suicide cluster is  defined as a group of […]

Background Well-organised and managed workplaces can be a source of wellbeing. The construction, healthcare and information and communication technology sectors are characterised by work-related stressors (e.g. high workloads, tight deadlines) which are associated with poorer mental health and wellbeing. The MENTUPP intervention is a flexibly delivered, multi-level approach to supporting small- and medium-sized enterprises (SMEs) […]

Background: Adverse childhood experiences (ACEs) have been well recognized as risk factors for various adverse outcomes. However, the impacts of ACEs on psychological wellbeing among Chinese children and adolescents are unknown. Methods: In total, 27 414 participants (6592 Grade 4–6 and 20 822 Grade 7–12 students) were included and information on ACEs and various psychosocial […]

Background: This study investigated the frequency, characteristics, and geospatial clustering of hotel suicides in Australia to inform suicide prevention efforts. Aims: (1) To determine the proportion of suicide deaths that occurred in hotels, (2) to determine differences in demographic characteristics of hotel deaths compared to other locations, (3) to assess level of planning, and (4) to determine whether […]

Background This study aimed to (i) identify high-risk suicide-methods clusters, based on location of residence and suicide incidence; and (ii) compare the characteristics of cases and spatial units inside and outside clusters. Methods Suicide data of 4672 cases was obtained from the Coroner’s Court reports in Hong Kong (2014–2018). Monthly aggregated suicide numbers based on […]

Late-in-life suicide is a major public health issue, with adults over 65 comprising 18% of all suicide deaths. Yet, little research has identified geographic concentrations of older populations at-risk for the psychological conditions in the pathway of suicide. This research identified spatial clustering of suicide, anxiety, depression, and self-injury among older adults in North Carolina […]

Background: Subthreshold hypomania during a major depressive episode challenges the bipolar-unipolar dichotomy. In our study we employed a cross-diagnostic cluster analysis – to identify distinct subgroups within a cohort of depressed patients. Methods: A k-means cluster analysis- based on the domain scores of the Mood Spectrum Self-Report (MOODS-SR) questionnaire-was performed on a data set of 300 adults […]

Background: Suicide rate is much higher in cancer patients than in general population. This study examined the suicide risk in survivors of primary solid tumor across 19 cancer sites considering risk coincident patterns based on area-based SES indicators. Methods: A retrospective search of the SEER database was conducted. Independent risk factors for suicide were identified […]

The purpose of this study was to include youth, parents, researchers, and clinicians in the identification of feasible and acceptable strategies for teen suicide screening in the pediatric emergency department (ED). Concept mapping methodology was used to elicit stakeholder responses. Regarding the most important result of suicide screening for teens in the pediatric ED, suicide […]

BACKGROUND: It is essential to understand the latent structure of the population of suicide attempters for effective suicide prevention. The aim of this study was to identify subgroups among Korean suicide attempters in terms of the details of the suicide attempt. METHODS: A total of 888 people who attempted suicide and were subsequently treated in […]

Objective This study describes characteristics of United States Air Force (USAF) suicide decedents and determines subgroups. Method Retrospective review of demographic, psychiatric, event‐related, and psychosocial variables for USAF suicide decedents in the Suicide Event Surveillance System database was conducted between February 1999 and July 2009 (N = 376). Hierarchical cluster analysis was used to determine initial clusters […]

Purpose This study aims to describe and characterize the spatial and temporal clustering patterns of suicide in the ten states with the greatest suicide burden in the United States from 1999 to 2016. Methods All suicide deaths from January 1, 1999 to December 31, 2016 in the United States were identified using data from the Wide-ranging […]

Suicides occur in metro systems worldwide and patterns vary in different urban transit networks. Aims: This study presents an in-depth analysis of 117 suicides in the Montreal Metro from 2000 to 2008 based on data obtained from coroners’ investigations. Method: Cluster analyses were performed to identify characteristics of groups of people who kill themselves in […]

Attempts to predict suicidal behavior within high-risk populations have so far shown insufficient accuracy. Although several psychosocial and clinical features have been consistently associated with suicide attempts, investigations of latent structure in well-characterized populations of suicide attempters are lacking. METHODS: We analyzed a sample of 1,009 hospitalized suicide attempters that were recruited between 1999 and […]

The older population are at a high risk for suicide. This study sought to learn more about the characteristics of suicide in the oldest-old and to use a cluster analysis to determine if oldest-old suicide victims assort into clinically meaningful subgroups. The younger and older age groups differed according to marital status, living circumstances and […]
