Grief and Attitudes Toward Suicide in Peers Affected by a Cluster of Suicides as Adolescents

Eighty‐five young adults exposed to a cluster of peer suicides as adolescents completed measures of attitudes toward suicide, grief, and social support. Closeness to the peers lost to suicide was positively correlated with grief and the belief that suicide is not preventable, with grief further elevated in close individuals with high social support from friends. Overall, social support was related to healthy attitudes about suicide including preventability, yet it was also related to some stigmatizing beliefs. Compared with 67 young adults who had not been exposed to a suicide cluster, the exposed sample was more likely to think that suicide is normal but more likely to think of it as incomprehensible.     

Frequency of Nonsuicidal Self‐Injury in Adolescents: Differences in Suicide Attempts,Substance Use,and Disordered Eating

The relationship between frequency of nonsuicidal selfinjury (NSSI) and suicide attempts, substance use, and disordered eating was assessed in a community sample of 4,839 adolescents, 922 of whom reported NSSI in the past year. It was expected that the engagement in risk behaviors would significantly increase as NSSI frequency increased. Participants completed the Youth Risk Behavior Survey (Centers for Disease Control and Prevention, 2009) and were subdivided into five NSSI frequency groups: none, 1 time, 2–3 times, 4–5 times, and 6 or more times. A one‐way MANOVA found significant mean differences for all variables across NSSI frequency groups. The no NSSI group was significantly lower than all other groups on all variables. For suicide attempts, all frequency groups were significantly different from each other, with attempt frequency increasing with each increase in NSSI frequency. The six or more group reported significantly more substance use and disordered eating than all other groups. Overall, adolescents with more frequent NSSI represent a group at risk for concurrent unhealthy behaviors and suicide attempts.     

Does adolescent heavier alcohol use predict young adult aggression and delinquency? Parallel analyses from four Australasian cohort studies

While the association between heavy alcohol consumption and aggression has been well documented, the causal direction of this association, particularly at a population level, is disputed. A number of causal sequences have been proposed. First, that aggression leads to heavy alcohol use. Second, that heavy alcohol use leads to aggression. Third, that the association between alcohol use and aggression is due to confounding by (a) sociodemographic variables or (b) delinquency. We report here data from four Australasian prospective longitudinal studies of adolescents, to assess the temporal sequence of heavy drinking and aggression over the period from adolescence to young adulthood. The four cohort studies provide a total sample of 6,706 persons (Australian Temperament Project, n = 1701; Christchurch Health and Development Study, n = 931; Mater-University of Queensland Study of Pregnancy, n = 2437; Victorian Adolescent Health Cohort Study, n = 1637). We use multinomial logistic regression to determine whether early adolescent aggression predicts subsequent age of onset of heavy episodic drinking (HED), after adjustment for concurrent sociodemographic factors and delinquency. We then consider whether HED predicts subsequent aggression, after adjusting for past aggression, concurrent delinquency, and a range of confounders. There are broadly consistent findings across the four cohort studies. Early aggression strongly predicts subsequent HED. HED predicts later aggression after adjustment for prior aggression and other confounders. Policies that alter population levels of alcohol consumption are likely to impact on levels of aggression in societies where HED linked to aggression is more common.     

Suicidal Behavior Outcomes of Childhood Sexual Abuse: Longitudinal Study of Adjudicated Girls

Childhood sexual abuse (CSA) histories are prevalent among adolescent girls in the juvenile justice system (JJS) and may contribute to their high rates of suicidal behavior. Among 166 JJS girls who participated in an intervention trial, baseline CSA and covariates were examined as predictors of suicide attempt and nonsuicidal self‐injury (NSSI) reported at long‐term follow‐up (7–12 years later). Early forced CSA was related to lifetime suicide attempt and NSSI history and (marginally) to postbaseline attempt; effects were not mediated by anxiety or depressive symptoms. Findings suggest that earlier victimization and younger entry into JJS are linked with suicide attempt and NSSI.     

A Minority Stress Model for Suicidal Ideation in Gay Men

There is a dearth of research on mechanisms underlying higher rates of suicidal ideation among gay men compared to heterosexual men. The purpose of this study was to establish the link between social/psychological predictor variables and suicidal ideation by testing a hypothesized minority stress model. Structural equation modeling was used to assess the relationships posited in the model using data from a community sample of 167 gay men. Model fit was adequate and hypothesized relationships were partially supported. Also, depressive symptoms partially mediated the relationship between (less) outness predicting suicidal ideation. These findings imply that therapeutic approaches targeting the coming out process may be more effective than approaches targeting internalized homophobia when suicidal ideation is indicated in the clinical presentation of gay and bisexual men.     

Identifying Risk for Self‐Harm: Rumination and Negative Affectivity in the Prospective Prediction of Nonsuicidal Self‐Injury

Research suggests nonsuicidal self‐injury (NSSI) may function as a maladaptive strategy to regulate negative emotions, and individuals high in trait negative affectivity (NA) may be particularly at risk. Rumination, a cognitive emotion regulation strategy, may amplify negative affect, increasing the likelihood of NSSI. The current study found that high NA and high rumination interacted to predict both likelihood of engagement in NSSI and frequency of NSSI. This study provides support for the joint contribution of cognitive and temperamental factors impacting the relationship between NA and NSSI and suggests that interventions targeted at maladaptive emotion regulation strategies may help inform individualized treatment.     

Predictors and Outcomes of Psychiatric Hospitalization in Youth Presenting to the Emergency Department with Suicidality

Youth suicide attempters presenting to the emergency department (ED) are frequently admitted to psychiatric inpatient hospitals, yet little is known about how clinicians decide which youths to admit versus discharge to outpatient care. We examine predictors of inpatient hospitalization and describe service use outcomes associated with hospitalization in 181 youths drawn from consecutive ED admissions for suicidality. Predictors of hospitalization include ED site, suicide plan, and parent report of problems. Hospitalization was associated with improved linkage to outpatient treatment and more intensive service use. Future research is needed to understand the best service delivery and treatments for these high‐risk youth.
