Nonsuicidal self‐injury (NSSI) is a risk factor for suicide attempts, but little is known about NSSI among military personnel and veterans, or about the temporal sequencing of NSSI relative to suicide ideation and attempts. This study evaluates trajectories of suicide ideation, NSSI, and suicide attempts in a sample of 422 military personnel and veterans. Of those with a history of NSSI, 77% also experienced suicide ideation. Suicide ideation emerged before NSSI (67%) more often than the reverse (17%). Of those with a history of suicide attempt, 41% also engaged in NSSI. NSSI emerged prior to the first suicide attempt (91%) more often than the reverse (9%). The length of time from suicide ideation to suicide attempt was longer for those who first engaged in NSSI (median = 3.5 years) compared with those who did not engage in NSSI (median = 0.0 years), Wald χ2(1) = 11.985, p = .002. Age of onset was earlier for participants reporting NSSI only compared with those reporting both NSSI and suicide attempts (16.71 vs. 22.08 years), F(1, 45) = 4.149, p = .048. NSSI may serve as a “stepping stone” from suicide ideation to attempts for 41% of those who attempt suicide. 相似文献

The prevalence of suicidal ideation/behavior in 1983 or 1987 and its association with future mental health in 2001 were evaluated in a provincially representative sample of Canadian adolescents (n = 1,248) aged 12 to 16 years. Approximately 13.3% (95% CI = 11.5–15.3) of adolescents self‐reported suicidal ideation/behavior. Adolescent agreement with parent (κ = .07) and teacher (κ = .05) reports at baseline was low because adults identified so few subjects. In adulthood, the associations between adolescent self‐reports of suicidal behavior/ideation and major depression and other mental health indicators were explained by respondent sex and adolescent emotional problems reported in 1983/1987. Adolescents with suicidal behavior/ideation often are not recognized by their parents and teachers and may be at risk for persistent psychiatric problems attributable to coexisting mental health problems early‐on. 相似文献

Objective measures of suicide risk can convey life‐saving information to clinicians, but few such measures exist. This study examined an objective measure of fearlessness about death (FAD), testing whether FAD relates to self‐reported and physiological aversion to death. Females (n = 87) reported FAD and disgust sensitivity, and facial electromyography was used to measure physiological facial responses consistent with disgust while viewing death‐related images. FAD predicted attenuated expression of physiological death aversion, even when controlling for self‐reported death‐related disgust sensitivity. Diminished physiological aversion to death‐related stimuli holds promise as an objective measure of FAD and suicide risk. 相似文献

We examined the associations between mental disorders and suicidal behavior (ideation, plans, and attempts) among new soldiers using data from the New Soldier Study (NSS) component of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS; N = 38,507). Most new soldiers with a pre‐enlistment history of suicide attempt reported a prior mental disorder (59.0%). Each disorder examined was associated with increased odds of suicidal behavior (ORs = 2.6–8.6). Only PTSD and disorders characterized by irritability and impulsive/aggressive behavior (i.e., bipolar disorder, conduct disorder, oppositional defiant disorder, and attention‐deficit/hyperactivity disorder) predicted unplanned attempts among ideators. Mental disorders are important predictors of pre‐enlistment suicidal behavior among new soldiers and should figure prominently in suicide screening and prevention efforts. 相似文献

错失恐惧是社交网络成瘾的风险因素,但其中的作用机制并不清楚。本研究采用错失恐惧问卷、社交网络整合性使用量表、社交网络支持量表和中文社交网络成瘾量表,调查了重庆市三所高校的493名大一至大三的学生,探讨错失恐惧影响社交网络成瘾的机制。结果发现:(1)错失恐惧显著预测社交网络成瘾,错失恐惧水平越高,个体社交网络成瘾水平越高。(2)社交网络整合性使用在错失恐惧和社交网络成瘾之间起独立中介作用。(3)社交网络支持在错失恐惧和社交网络成瘾之间起独立中介作用。(4)社交网络整合性使用和社交网络支持在错失恐惧和社交网络成瘾之间起链式中介作用。研究结果表明,满足大学生基本心理需要、降低社交网络使用程度、提升现实社会支持可以有效预防社交网络成瘾。 相似文献

We examined teenagers' attitudes about the role of mental illness in suicidal behavior and the relationship between these attitudes and suicide risk. Serious suicidal ideation or behavior and associated risk factors (gender, depression, substance problems, and first‐hand experience with a suicidal peer) were assessed in 2,419 students at six New York high schools. Less than one fifth of students thought that mental illness was a major contributor to suicide. Suicidal adolescents and those at risk were less likely than their nonsuicidal and low‐risk counterparts to associate suicide with mental illness. Our findings contribute to the debate over whether accepting attitudes toward suicide increase suicide risk. 相似文献

The motives of suicide attempts among a community sample of 99 U.S. high school students were explored. Participants completed an in‐depth computer‐assisted self interview about their most recent attempts as well as additional psychosocial measures. Results indicated that nearly 75% of the adolescents engaged in suicide attempts for reasons other than killing themselves and that depressive symptoms and premeditation prior to the attempt were significantly associated with increased risk for engaging in the attempts with death as a clear motive. Linking motive for an attempt (death, interpersonal communication, emotion regulation) and treatment approach may improve prevention of subsequent attempts and completed suicides. 相似文献

Past studies on suicide have investigated the association of firearm ownership and suicide risk in the United States. The aim of the present study was to build on previous work by examining the impact of firearm storage practices and the strictness of firearm regulation on suicide rates at the state level. Data were compiled from primarily three sources. Suicide and firearm ownership information was obtained from the Centers for Disease Control and Prevention. Strictness of handgun regulation was derived from figures available at the Law Center to Prevent Violence, and controls were taken from the US Bureau of the Census. Mixed models were fitted to the data. Household firearm ownership was strongly associated with both suicide by all mechanisms, and firearm suicide. Storage practices had especially elevated consequences on suicide rates. Percent with loaded guns and gun readiness increased suicide rates, and strictness of gun regulation reduced suicide rates. Ready access to firearms can make a difference between life and death. Loaded and unlocked firearms within reach become risk factors for fatal outcomes from suicidal behavior. Future research might want to examine ways of obtaining more recent data on individual firearm ownership. This study proposes several policy recommendations for suicide prevention. 相似文献
