Sexual orientation‑related patterns of 12‑month course and severity of suicidality in a longitudinal, population‑based cohort of young adults in Sweden

Purpose We assessed sexual orientation-related patterns in the 1-year longitudinal course (i.e., onset, remittance, persistence) and severity of suicidality. Method Data were obtained from a prospective, population-based cohort representing nearly 2.4 million Swedish young adults. Results A higher proportion of sexual minorities remitted (14.6%) compared to heterosexuals (9.5%). However, over twice as many sexual minorities […]

The developmental origins of suicide mortality: A systematic review of longitudinal studies

Suicide prevention efforts generally target acute precipitants of suicide, though accumulating evidence suggests that vulnerability to suicide is partly established early in life before acute precipitants can be identified. The aim of this systematic review was to synthesize evidence on early life vulnerability to suicide beginning in the prenatal period and extending through age 12. […]

A longitudinal study of correlates, discharge disposition, and rate of re-presentation to emergency services of adults who engage in non-suicidal self-injury

Objective In DSM-5, non-suicidal self-injury (NSSI) and suicide attempts (SA) are classified as distinct disorders in the section of conditions for further study. However, some have questioned the validity of distinguishing NSSI from SA. The objective of this study was to longitudinally examine the correlates, discharge disposition, and rate of re-presentation to emergency services of […]

Longitudinal intercorrelations between complicated grief and posttraumatic growth among suicide survivors

Background Suicide survivors are prone to elevated risk for several psychiatric and somatic complications, including complicated grief (CG) and depression. Recent studies have highlighted the possibility of posttraumatic growth (PTG) among suicide survivors. However, to date, no longitudinal study has focused on the relationships between CG and PTG among suicide survivors. Aims In this 18-month […]

Prospective pathways from impulsivity to non-suicidal self-injury among youth

Non-suicidal self-injury (NSSI) is a common behavior, particularly among adolescents and young adults. Impulsivity has been implicated as an important factor associated with NSSI, however prospective longitudinal research is lacking. Moreover, the relationship between impulsivity and other risk factors for NSSI is unclear. By examining longitudinal models including impulsivity, attachment, and distress we hope to […]

Does nonsuicidal self-injury predict later suicidal attempts? A review of studies

Co-occurrence of nonsuicidal self-injury (NSSI) and suicide attempts (SA) might occur because they share common risk factors, or alternatively because one leads to the other. Using search terms salient to NSSI and SA, we screened 555 studies to identify 17 that presented temporal data about NSSI and SA. Much of the evidence indicates that NSSI […]

A one-year longitudinal study on suicidal ideation, depression and anxiety during the COVID-19 pandemic

The impact of working as a peer worker in mental health services: A longitudinal mixed methods study

Background Peer workers are increasingly employed in mental health services to use their own experiences of mental distress in supporting others with similar experiences. While evidence is emerging of the benefits of peer support for people using services, the impact on peer workers is less clear. There is a lack of research that takes a […]

Are suicidal thoughts and behaviors a temporary phenomenon in early adolescence?

Background: The incidence of first suicidal thoughts and behaviors (STBs) peaks during early adolescence. After experiencing their first STBs, adolescents differ greatly in the extent to which they continue to have STBs. Aim: We determined the course of STBs in Dutch students at two ages: 13–14 years (t1) and 15–16 years (t2). Methods: Longitudinal data on STBs and sociodemographic factors […]

The influence of personality disorder in predicting suicidal behaviour in common mental disorders: A 30-year study

Two hundred ten patients with anxiety and depressive disorders were followed up over 30 years. Personality status was assessed at baseline using the Personality Assessment Schedule (PAS), an instrument that classifies personality disorder in a similar way to the new ICD-11 classification. Assessments of suicidal behaviour were made at 5, 12 and 30 years and […]

Physical activity, mental and physical health during the Covid‑19 outbreak: Longitudinal predictors of suicide ideation in Germany

Aim: Suicide ideation has increased since the outbreak of Covid-19 in many countries. The present longitudinal study investigated potential predictors of suicide ideation. Subject and methods: Data of 406 participants from Germany (age M = 27.69, SD = 6.88) were assessed via online surveys in spring 2020 (baseline, BL) and in spring 2021 (follow-up, FU). Results: The current results reveal a significant […]

Pain and suicidality in children and adolescents: A longitudinal population‑based study

Suicidality is a common public health concern in young people. Previous research has highlighted pain as a key correlate of suicidality in young people. However, the long-term experience of pain may vary between individuals, and the relationship between distinct pain trajectories and suicidality is poorly understood. This study aims to describe the number and nature […]

Longitudinal effects of physical and social neighbourhood change on suicide mortality: A full population cohort study among movers and non-movers in the Netherlands

Associations between the residential neighbourhood environment and suicide mortality are well-established; however, most evidence is cross-sectional and not capable of incorporating place-based and residential moving-related neighbourhood changes. We studied how suicide mortality is associated with changes in the physical and social neighbourhood environment for movers and non-movers. Our retrospective analysis was based on longitudinal register data for […]

Ecological momentary assessment of mental health in adults at suicide risk: An observational study protocol
