Findings from 55 psychological autopsies of decedents who perished on U.S. railroad rights‐of‐way between October 1, 2007, and September 30, 2010 are reported. Described are distal, proximal, and contextual factors of risk; understandings of why these suicides occurred on railroad rights‐of‐way; and opportunities for prevention of similar suicides. International comparisons of suicides on railroad rights‐of‐way are made to highlight distinct findings regarding U.S. cases. Decedents studied exhibited considerable predisposing risk for suicide, with a high prevalence of severe mental disorders and substance abuse. In addition, a number of acute risk factors were commonly observed, notably suicide ideation, hopelessness, anxiety, and anger. In the context of that acute risk, associated situational variables and a relative absence of protective factors are described.  相似文献

The link between violence and suicide is well documented. Previous studies, however, largely rely on cross‐sectional designs or only consider violence as an antecedent of suicide. The purpose of the current study was to investigate the longitudinal relationship between violence and suicide from adolescence into young adulthood. Data were derived from Wave II (1995–1996), Wave III (2001–2002), and Wave IV (2007–2008) of the National Longitudinal Study of Adolescent Health (= 8,966). We tested (2011–2013) a series of path analysis models in Mplus to determine the longitudinal associations between violence and suicidality. Results from the path analyses indicated that violence and suicidality mutually affect each other from adolescence into young adulthood. We found some evidence that the association between suicidality and violence was stronger for males compared to females, particularly in early and young adulthood. The current study confirms previous findings by demonstrating that violence is a risk factor for future suicide. We also extended the previous literature by demonstrating that a history of suicidality is associated with future risk for violence. Our findings highlight the importance of further integrating prevention efforts to reduce violence and suicidality during adolescence and early/young adulthood.  相似文献

The objective of the current study was to characterize the association between dating violence victimization and dispositional aggression in predicting nonsuicidal self‐injury (NSSI) among psychiatrically hospitalized male and female adolescents. One hundred fifty‐five adolescents (ages 13–17) and their parents completed the Schedule for Affective Disorders and Schizophrenia for School‐Age Children clinical interview to assess NSSI and child abuse; adolescents completed self‐report measures of aggression and dating violence victimization (verbal, physical, and sexual). Dating violence victimization and NSSI were found to be highly prevalent among both males and females in this psychiatric inpatient sample. Two moderational models were supported, wherein dating violence was associated with NSSI in the context of elevated trait anger in males and indirect aggression in females. Findings suggest that helping victims of dating violence acquire skills to address certain forms of dispositional aggression may attenuate NSSI.  相似文献

Public knowledge and attitudes toward suicide may influence help‐seeking for suicidality. This study aimed to identify correlates of suicide attitudes and knowledge. Australian adults were invited to complete an online survey, with 1,286 responders. Less exposure to suicide, older age, male gender, less education, and culturally diverse backgrounds were associated with poorer knowledge; while younger age, male gender, and culturally diverse backgrounds were associated with more stigmatizing attitudes toward people who die by suicide. The results suggest suicide literacy and stigma reduction programs would benefit community members, particularly males and individuals from culturally diverse backgrounds.  相似文献

Suicide attempters who met criteria for borderline personality disorder (BPD) comorbid with major depressive disorder (MDD) were compared to both suicide attempters suffering from MDD alone and to attempters with comorbid MDD and other personality disorders (PD). Participants were 239 (158 patients with comorbid PD and 81 patients with MDD without comorbidity) inpatients consecutively admitted after a suicide attempt made in the last 24 hours. Suicide attempters with comorbid MDD and BPD had more frequent previous suicide attempts and were more likely to have a history of aggressive behaviors and alcohol and drug use disorders compared with patients suffering from MDD without Axis II comorbidity.  相似文献

The incidence rate of suicidal ideation among current and former smokers versus never smokers is not known. In this study, the age‐adjusted incidence of suicidal ideation was highest among current smokers, followed by former, then never smokers. The adjusted hazard for suicide ideation was 2.22 (95%CI = 1.48, 3.33) and 1.19 (95%CI = 0.78, 1.82) for current and former smokers, respectively, compared to never smokers. Results indicate that current smokers have increased risks of suicidal ideation above and beyond the risk for never and former smokers regardless of age, gender, history of depressive disorder or anxiety symptoms, and alcohol abuse/dependence. Smoking cessation might be beneficial for some suicide prevention efforts.  相似文献

Retraction: Christopher R. Hagan PhD, Jennifer J. Muehlenkamp PhD, “The Three-Step Theory of Suicide: An Independent Replication and Conceptual Extension,” Suicide and Life-Threatening Behavior, Wiley, © American Association of Suicidology The above article, published online on 30 September 2019 in Wiley Online Library ( wileyonlinelibrary.com ), has been retracted by agreement between the authors, the journal Editor in Chief, Thomas Joiner, PhD, and John Wiley and Sons Ltd. The retraction has been agreed due to errors in variable calculation and a post-publication reviewer's concerns that some analyses did not accurately test the theoretical model. An updated version of this article will soon undergo review for publication at Suicide and Life-Threatening Behavior, and if accepted for publication, will be accompanied by an editorial from the Editor-in-Chief.  相似文献

Relationships between self‐harm and vulnerability factors were studied in a general population of 432 participants, of whom 30% reported some experience of self‐harm. This group scored higher on dissociation and childhood trauma, had lower self‐worth, and reported more negative intrusive thoughts. Among the non‐harming group, 10% scored similarly to the self‐harmers on the dissociation and self‐worth scales, and engaged in potentially maladaptive behaviors that are not defined as indicating clinical self‐harm, but experienced fewer negative intrusive thoughts. This group may be at risk of future self‐harm if they begin to experience negative intrusive thoughts. If negative intrusive thoughts are playing a causal role, then therapeutic approaches tackling them may help those who are currently self‐harming.  相似文献

This study investigated the relation between symptoms and a variety of health‐related risk‐taking behaviors during adolescence. A survey of 20,745 adolescents from the National Longitudinal Study of Adolescent Health provided data for analysis. Adolescents who reported more depressive symptoms were found to wear seatbelts less often, wear bike‐helmets less often, and drive while drunk more frequently. Depressive symptoms did not correlate with reported condom use. The found relations were all mediated by reported levels of hopelessness. Reported levels of anhedonia and suicidality also mediated some of the found relations. Therefore, adolescents experiencing depressive symptoms, especially those reporting hopelessness, should be considered at jeopardy for a variety of health‐related risk‐taking behaviors.  相似文献
