Sociodemographic and psychosocial risk factors of railway suicide a mixed-methods study combining data of all suicide decedents in the Netherlands with data from a psychosocial autopsy study.

BACKGROUND: Railway suicide has profound implications for the victims and their family, and affects train drivers, railway personnel, emergency services and witnesses. To inform a multilevel prevention strategy, more knowledge is required about psychosocial and precipitating risk factors of railway suicide. METHODS: Data from Statistics Netherlands of all suicides between 2017 and 2021 (n = 9.241) of whom 986 died by railway suicide and interview data from a psychosocial autopsy of railway suicide decedents (n = 39) were integrated. We performed logistic regression analyses to identify sociodemographic predictors of railway suicide compared to other methods of suicide. The Constant Comparative Method was subsequently employed on interview data from the psychosocial autopsy to identify patterns in psychosocial risk factors for railway suicide. RESULTS: The strongest predictors of railway suicide compared to other suicide methods were young age (< 30 years old), native Dutch, a high educational level, living in a multi-person household (especially living with parents or in an institution), living in a rural area and a high annual household income of > 150.000 euros. Several subgroups emerged in the psychosocial autopsy interviews, which specifically reflect populations at risk of railway suicide. These subgroups were [1] young adult males with autism spectrum disorder who strived for more autonomy and an independent life, [2] young adult females with persistent suicidal thoughts and behaviours, [3] middle-aged males with a persistent mood disorder who lived with family and who faced stressors proximal to the suicide in personal and professional settings, [4] male out-of-the-blue suicides and [5] persons with psychotic symptoms and a rapid deterioration. CONCLUSIONS: based on our findings we propose and discuss several recommendations to prevent railway suicide. We must continue to invest in a safe railway environment by training personnel and installing barriers. Additionally, we should adopt prevention strategies that align the needs of subgroups at increased risk, including young females who have attempted other methods of suicide and young males with autism spectrum disorder. Future research should determine the cost-effectiveness and feasibility of low-maintenance, automated interventions near crossings and psychiatric facilities.

The forever decision: a qualitative study among survivors of a suicide attempt.

Background: Suicide attempts have a profound emotional impact on both individuals and society as a whole. This qualitative study delves into three key aspects: 1) the progression through the suicidal process, 2) the influential factors facilitating the transition from ideation to attempt using the volitional moderators within the integrated motivational-volitional (IMV) model, and 3) preventive strategies impeding this transition from ideation to attempt. Methods: Between October 1, 2022 and March 7, 2023 we interviewed 27 adults (23 women, four men, mean age 33 years) who attempted suicide within the past 12 months. Participants were recruited through social media and in collaboration with several mental health institutions in the Netherlands. The participants were initially screened and interviewed based on the Pathway to Suicidal Actions Interview. Analysis was performed employing the constant comparative method. Findings: Despite the heterogeneity of the suicidal process, suicidal thoughts predominately emerged during adolescence (Mdn = 15, M = 17.8). In most participants, planning and preparatory actions occurred long before the attempt, with a median of six years prior to the attempt for the selection of the method. All volitional moderators were observed, although pain sensitivity in particular varied among participants. Access to lethal means and planning emerged as important moderators in the suicidal process. Asking the survivors what could have helped to prevent their attempts, most participants mentioned that they felt their suicidality was not taken seriously enough. Interpretation: We discussed the significance of planning in the suicidal process, challenges in conceptualizing planning and impulsivity, and individual differences in pain sensitivity. Based on the findings, we underscore the critical need for restricting access to means, giving greater consideration to preparatory actions within the suicidal process, and fostering open dialogues about suicidality. Funding: This research was funded by ProRail, the Dutch rail infrastructure manager in line with their work on mental health.

Social media use of adolescents who died by suicide: lessons from a psychological autopsy study.

BACKGROUND: while there are many benefits for young people to use social media, adverse effects such as cyberbullying, online challenges, social comparison and imitation may provoke and aggravate suicidal thoughts and behaviors. The influence of social media on mental health and suicidal thoughts and behaviours has been amply studied, but there is little empirical evidence for its potential role in adolescent suicides. The current study aimed to inform digital suicide prevention strategies by examining the meaning of social media in the lives of young suicide victims and elucidating the harmful and supportive effects of social media use on their wellbeing and distress. METHODS: data were analyzed from a psychological autopsy study of 35 adolescents who died by suicide in the Netherlands (43% of all adolescents who died by suicide in that year). These were 18 girls and 17 boys. All were under the age of twenty years, with an average of seventeen years. Interpretative Phenomenological Analysis was performed of 55 semi structured interviews with peers and parents of the decedents. RESULTS: young people benefitted from peer support and recovery stories. However, various themes were discussed relating to the harmful effects of social media, including dependency, triggers and imitation, challenges, cybervictimization and psychological entrapment. The themes of dependency and triggers and imitation were more salient in young females. A group of girls cultivated an online identity around their suicidal thoughts and behaviours. Next-of-kin, particularly parents, faced various challenges to talk to the adolescents about social media use, including technological illiteracy, online anonymity, and the youths' closedness. CONCLUSIONS: based on the findings, we recommend education to stimulate the digital literacy of parents, health workers and educators, supporting conscientious social media use in young people, and extending the prevention of cyberbullying. We encourage future research to examine how virtual social networks may sustain suicidal thoughts and behaviour, and to further investigate the effectiveness of digital interventions, like moderated peer support and the use of positive role models.
