Physical Activity,Suicide Risk Factors,and Suicidal Ideation in a Veteran Sample

The association between current level of suicidal ideation and physical activity was tested in a broad sample of veterans seeking care from the Veterans Health Administration. It was hypothesized that the two variables would be significantly inversely related. It was further hypothesized that the relationship would be mediated by depressive symptoms, disturbed sleep, and a measure of heart rate variability based on existing research regarding physical activity and sleep. Due to the first hypothesis not being supported, the second could not be tested. Post hoc correlation analyses did find associations between physical activity and depressive symptoms, in expected directions, and are discussed. Possible explanations for the negative findings along with recommendations for future research to continue exploring links between suicide risk and physical activity are presented. We conclude by suggesting that physical activity may have promise as a risk reduction intervention and that prospective data are more likely to yield significant results than the cross‐sectional methodology employed in the current study.     

Trajectories of Suicidal Ideation from Sixth through Tenth Grades in Predicting Suicide Attempts in Young Adulthood in an Urban African American Cohort

The trajectory of suicidal ideation across early adolescence may inform the timing of suicide prevention program implementation. This study aimed to identify developmental trajectories of suicidal ideation among an urban cohort of community‐residing African Americans (AA) longitudinally followed from middle school through early adulthood (ages 11–19 years). Subtypes based on the developmental course of suicidal ideation from late childhood through mid‐adolescence were identified using longitudinal latent class analysis (LLCA) with 581 AA adolescents (52.7% male; 71.1% free or reduced school meals). The developmental trajectories of suicidal ideation were then used to predict suicide attempts in young adulthood. Our LLCA indicated two subtypes (i.e., ideators and nonideators), with 8% of the sample in the ideator class. This trajectory class shows a peak of suicidal ideation in seventh grade and a steady decline in ideation in subsequent grades. Additionally, suicidal ideation trajectories significantly predicted suicide attempt. Results of these analyses suggest the need for suicide prevention approaches prior to high school for AA youth.     

The Interactive Effects of Impulsivity and Negative Emotions on Adolescent Nonsuicidal Self‐injury: A Latent Growth Curve Analysis

This study employed latent growth curve analysis to evaluate the interactive effects of two specific facets of impulsivity (i.e., negative urgency [NU] and premeditation [PRE]) and negative emotions (NE) on the developmental trajectory of nonsuicidal self‐injury (NSSI) among 3,453 (57% females) Chinese community adolescents. Participants completed questionnaires assessing NSSI, NU, PRE, and NE (i.e., depression, anxiety, and stress) at three waves of time. The initial levels of NE and NU significantly predicted the initial level of NSSI. Changes in NE and NU significantly predicted change in NSSI. Moreover, the initial levels of NU and PRE significantly moderated the relationship between the initial levels of NE and NSSI, such that among individuals with higher NU or less PRE, the three NE were associated with a higher level of NSSI. Additionally, among individuals with a faster increase in NU, depression and anxiety were associated with a faster increase in NSSI. These findings suggest that adolescents with trait impulsivity, especially in the form of NU, are more vulnerable to the engagement in NSSI.     

Helping Callers to the National Suicide Prevention Lifeline Who Are at Imminent Risk of Suicide: Evaluation of Caller Risk Profiles and Interventions Implemented

Crisis lines are settings where identifying individuals at imminent risk of suicidal behavior and intervening to keep them safe are critical activities. We examined clinical characteristics of crisis callers assessed by telephone crisis helpers as being at imminent risk of suicide, and the interventions implemented with these callers. Data were derived from 491 call reports completed by 132 helpers at eight crisis centers in the National Suicide Prevention Lifeline network. Helpers actively engaged the callers in collaborating to keep themselves safe on 76.4% of calls and sent emergency services without the callers' collaboration on 24.6% of calls. Four different profiles of imminent risk calls emerged. Caller profiles and some helper characteristics were associated with intervention type. Our findings provide a first step toward an empirical formulation of imminent risk warning signs and recommended interventions.     

Factors that Influence Chaplains’ Suicide Intervention Behavior in the Army

We surveyed 868 Army chaplains and 410 chaplain assistants (CAs) about their role in identifying, caring for, and referring soldiers at risk of suicide to behavioral health care. We applied structural equation modeling to identify how behaviors and attitudes related to intervention behavior. In both samples, reluctance and stigma were related to intervention behaviors; efficacy was correlated with intervention behaviors only among chaplains. Training was associated with increased efficacy and lower levels of stigma among chaplains. Improved training may be warranted, but research needs to identify why chaplains and CAs are reluctant to refer soldiers in distress to behavioral health care.     

Factors Associated with Achieving Complete Mental Health among Individuals with Lifetime Suicidal Ideation

The objective of this study was to identify factors associated with complete mental health among Canadians who had ever seriously considered suicide. Data for this study were obtained from Statistics Canada's 2012 Canadian Community Health Survey–Mental Health (N = 2,844). The outcome variable examined in this study was complete mental health and was analyzed using binary logistic regression. Of the 2,844 respondents with lifetime suicidal ideation, 1,088 (38.2%) had complete mental health (i.e., had flourishing mental health, no mental illness, and no suicidal ideation in the past 12 months). Those who had a confidant were seven times more likely to have complete mental health. Other factors associated with achieving complete mental health among formerly suicidal respondents include being older, being a woman, having higher income, use of religious coping, and never previously having a mental illness. Considering the importance of these protective factors in formulating public health policies will allow for a more wide‐reaching approach to suicide prevention.     

The Incremental Utility of Emotion Regulation But Not Emotion Reactivity in Nonsuicidal Self‐Injury

This study assessed the incremental utility of emotion reactivity and emotion regulation in relation to nonsuicidal self‐injury (NSSI). Participants included 379 college students aged 18–22 who completed self‐report measures of emotion regulation, emotion reactivity, and NSSI. Emotion regulation was significantly related to NSSI both ignoring and controlling for reactivity, but the reverse was not true. Participants' use of NSSI for affect regulation appeared to moderate this relation. Findings support emotion regulation deficits as a target for intervention over and above heightened emotion reactivity, especially in those who use NSSI to regulate negative affect.

自闭症儿童视觉动态信息的注意加工特点——来自多目标追踪任务的证据

为了考察中低功能自闭症儿童在动态条件下的多目标注意加工特点,研究采用多目标追踪实验范式,具体追踪任务采用多目标随机运动和碰撞反弹算法。实验设计为两因素混合设计,组间变量为年龄和性别匹配的中低功能自闭症和正常儿童组,组内变量为追踪目标数量（分别为1、2、3、4个目标）,因变量为被试在多目标追踪任务中的追踪正确率和追踪容量。结果发现：（1）中低功能自闭症儿童在目标数量为1到目标数量为4时的正确率均明显低于正常儿童,且标准差变异较大,中低功能自闭症儿童的多目标的持续追踪能力和稳定性存在一定的缺陷;（2）当目标数量为1时,正常组儿童与中低功能自闭症儿童的追踪容量差异不显著;目标为2、3、4时,两组追踪容量差异均显著。不同目标数量情况下中低功能自闭症儿童平均的注意容量为0.83~1.24个（平均容量约为1个）明显低于正常儿童的0.95~3.72个（最大容量接近4个）。中低功能自闭症儿童在多目标追踪上表现为单焦点注意加工的特点,存在一定程度的注意转移缺陷。     

What Factors Determine Disclosure of Suicide Ideation in Adults 60 and Older to a Treatment Provider?

Correlates of patient disclosure of suicide ideation to a primary care or mental health provider were identified. Secondary analyses of IMPACT trial data were conducted. Of the 107 patients 60 years of age or older who endorsed thoughts of ending their life at least “a little bit” during the past month, 53 indicated they had disclosed these thoughts to a mental health or primary care provider during this period. Multiple logistic regression was used to identify predictors of disclosure to a provider. Significant predictors included poorer quality of life and prior mental health specialty treatment. Among participants endorsing thoughts of suicide, the likelihood of disclosing these thoughts to a provider was 2.96 times higher if they had a prior history of mental health specialty treatment and 1.56 times higher for every one‐unit decrease in quality of life. Variation in disclosure of thoughts of suicide to a mental health or primary care provider depends, in part, on patient characteristics. Although the provision of evidence‐based suicide risk assessment and guidelines could minimize unwanted variation and enhance disclosure, efforts to routinize the process of suicide risk assessment should also consider effective ways to lessen potential unintended consequences.
