Sequelae of Aggression in Acutely Suicidal Adolescents

Aggressive Behaviors and Suicide Ideation in Inpatient Adolescents: The Moderating Roles of Internalizing Symptoms and Stress

The present study examined a conceptual model in which the association between aggressive behaviors and suicide ideation is moderated by internalizing symptoms and ongoing stress. Participants were 304 psychiatric inpatient adolescents (65.8% girls) ranging in age from 12 to 17 years (Mean age = 14.69). The association between aggressive behaviors and suicide ideation was significantly moderated by internalizing symptoms and ongoing stress; the association was positive in adolescents low in internalizing symptoms or high in ongoing stress, but negative in adolescents high in internalizing symptoms or low in ongoing stress. The three-way interaction between aggressive behaviors, internalizing symptoms, and ongoing stress was not statistically significant. The current findings indicate that in adolescents who display high levels of aggressive behaviors, the presence of high ongoing stress provides a more useful indicator of levels of suicide ideation than the presence of high internalizing symptoms. Implications for case identification and prevention are discussed.

Emergency Department Youth Patients With Suicidal Ideation or Attempts: Predicting Suicide Attempts Through 18 Months of Follow-Up

This prospective study of suicidal emergency department (ED) patients (ages 10-18) examined the timing, cumulative probability, and predictors of suicide attempts through 18 months of follow-up. The cumulative probability of attempts was as follows: .15 at 6 months, .22 at 1 year, and .24 by 18 months. One attempt was fatal, yielding a death rate of .006. Significant predictors of suicide attempt risk included a suicide attempt at ED presentation (vs. suicidal ideation only), nonsuicidal self-injurious behavior, and low levels of delinquent symptoms. Results underscore the importance of both prior suicide attempts and nonsuicidal self-harm as risk indicators for future and potentially lethal suicide attempts.

Metasynthesis of youth suicidal behaviours: perspectives of youth, parents, and health care professionals

BACKGROUND

Youth suicide is a major public health issue throughout the world. Numerous theoretical models have been proposed to improve our understanding of suicidal behaviours, but medical science has struggled to integrate all the complex aspects of this question. The aim of this review is to synthesise the views of suicidal adolescents and young adults, their parents, and their healthcare professionals on the topics of suicidal behaviour and management of those who have attempted suicide, in order to propose new pathways of care, closer to the issues and expectations of each group.

METHODS AND FINDINGS

This systematic review of qualitative studies--Medline, PsycInfo, Embase, CINAHL, and SSCI from 1990 to 2014--concerning suicide attempts by young people used thematic synthesis to develop categories inductively from the themes identified in the studies. The synthesis included 44 studies from 16 countries: 31 interviewed the youth, 7 their parents, and 6 the healthcare professionals. The results are organised around three superordinate themes: the individual experience, that is, the individual burden and suffering related to suicide attempts in all three groups; the relational experience, which describes the importance of relationships with others at all stages of the process of suicidal behaviour; and the social and cultural experience, or how the group and society accept or reject young people in distress and their families and how that affects the suicidal process and its management.

CONCLUSION

The violence of the message of a suicidal act and the fears associated with death lead to incomprehension and interfere with the capacity for empathy of both family members and professionals. The issue in treatment is to be able to witness this violence so that the patient feels understood and heard, and thus to limit recurrences.

An evidence synthesis of risk identification, assessment and management for young people using tier 4 inpatient child and adolescent mental health services

Background

Inpatient child and adolescent mental health services are one part of a complex system, and exist to meet the needs of young people with the greatest mental health difficulties.

Objectives

The research question was ‘What is known about the identification, assessment and management of risk (where “risk” is broadly conceived) in young people (aged 11–18 years) with complex mental health needs entering, using and exiting inpatient child and adolescent mental health services in the UK?’

Data sources

The two-phase Evidence for Policy and Practice Information and Co-ordinating Centre approach was used. In phase 1, scoping searches were made using two databases with an end date of March 2013. Phase 2 centred on the search for citations relating to the risks to young people of ‘dislocation’ and ‘contagion’. Searches were made using 17 databases, with time limits from 1995 to September 2013. Websites were searched, a call for evidence circulated and references of included citations reviewed.

Review methods

Priority risk areas for phase 2 were decided in collaboration with stakeholders including through consultations with young people and the mother of a child who had been in hospital. All types of evidence relating to outcomes, views and experiences, costs and cost-effectiveness, policies, and service and practice responses in the areas of ‘dislocation’ and ‘contagion’ for young people (11–18 years) using inpatient mental health services were considered. A staged approach to screening was used. Data were extracted into tables following guidance from the Centre for Reviews and Dissemination or tables developed for the review. Quality was assessed using appraisal checklists from the Effective Public Health Practice Project or the Critical Skills Appraisal Programme or devised by previous reviewers. No papers were excluded on the grounds of quality, and all materials identified were narratively synthesised.

Results

In phase 1, 4539 citations were found and 124 included. Most were concerned with clinical risks. In phase 2, 15,662 citations were found and 40 addressing the less obvious risks of ‘dislocation’ and ‘contagion’ were included, supplemented by 20 policy and guidance documents. These were synthesised using these categories: Dislocation: Normal Life; Dislocation: Identity; Dislocation: Friends; Dislocation: Stigma; Dislocation: Education; Dislocation: Families; and Contagion. No studies included an economic analysis or economic evaluation. The importance to stakeholders of these less obvious risks contrasted with the limited quantity and quality of research capable of informing policy, services and practice in these areas.

Limitations

Included studies were of variable quality. Data derived could not be used to inform an economic modelling of NHS costs or to analyse cost-effectiveness. Other limitations were the search for only English-language materials and the use of umbrella concepts (‘dislocation’ and ‘contagion’).

Conclusions

The less obvious risks are important, but little evidence exists to support their identification, assessment and management. This has implications for services, and a programme of research is recommended to generate new knowledge.

Parents and friendships: a longitudinal examination of interpersonal mediators of the relationship between child maltreatment and suicidal ideation

This study examined parental relationship quality, friendship quality, and depression as mediators of the association between child maltreatment (CM) and adolescent suicidal ideation (SI). Participants were 674 adolescents (46% female; 55% African American) involved in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Data were collected via youth self-report at ages 12, 16, and 18. CM before age 12 predicted poor parental relationships and depression, but not poor friendships, at age 16. Age 16 depression was negatively associated with parental relationship quality and positively associated with SI at age 18. An indirect path from CM to SI via depression was significant, suggesting that the early CM affects depression severity, which in turn is associated with SI. Strong friendship quality (age 16) was associated with SI at age 18; however, there was no significant indirect path from CM to SI via friendships. Results suggest that: 1) CM before age 12 affects parental relationships in adolescence; 2) depression and friendships are related to suicide ideation in later adolescence; and 3) depression partially mediates the association between CM and SI. Results highlight the importance of assessing for a history of CM, quality of interpersonal relationships, and depression severity among youth reporting SI.

Acutely suicidal adolescents who engage in bullying behavior: 1-year trajectories

PURPOSE

Prospective longitudinal research is needed to examine associations between bullying behaviors and trajectories of suicidal ideation and behavior and overall functional impairment. The specific aims of the present study are to: (1) characterize differences in baseline functioning between acutely suicidal adolescents who are classified into bullying perpetrator and non-bully groups and (2) examine the 1-year trajectories of these two groups of adolescents.

METHOD

Participants were 433 psychiatrically hospitalized suicidal adolescents (72% female), ages 13 to 17 years. Participants reported suicidal ideation, depression, anxiety, substance use, adaptive functioning, and bullying behavior. Six items from the Youth Self-Report were used to classify adolescents into bullying perpetrator (n = 54) and non-bully (n = 379) groups. Follow-up assessments were conducted at 6 weeks, 3 months, 6 months, and 12 months.

RESULTS

At hospitalization, adolescents in the bully group reported significantly higher levels of suicidal ideation, substance use, and functional impairment. Suicidal ideation differences remitted at six weeks. The elevated functional impairment of the bullying perpetrator group persisted across the 12-month period.

CONCLUSION

Adolescents who met bullying perpetrator group criteria were characterized by more severe suicidal ideation and higher levels of proximal risk factors for suicide. Bullying behavior was not stable over time but was associated with elevated suicide risk when present. These findings highlight the importance of specifically assessing for and targeting bullying behavior at multiple time points when treating suicidal adolescents.

Prospective predictors of adolescent suicidality: 6-month post-hospitalization follow-up

BACKGROUND

The aim of this study was to examine prospective predictors of suicide events, defined as suicide attempts or emergency interventions to reduce suicide risk, in 119 adolescents admitted to an in-patient psychiatric unit for suicidal behaviors and followed naturalistically for 6 months. Method Structured diagnostic interviews and self-report instruments were administered to adolescent participants and their parent(s) to assess demographic variables, history of suicidal behavior, psychiatric disorders, family environment and personality/temperament.

RESULTS

Baseline variables that significantly predicted time to a suicide event during follow-up were Black race, high suicidal ideation in the past month, post-traumatic stress disorder (PTSD), childhood sexual abuse (CSA), borderline personality disorder (BPD), low scores on positive affectivity, and high scores on aggression. In a multivariate Cox regression analysis, only Black race, CSA, positive affect intensity and high aggression scores remained significant.

CONCLUSIONS

Our findings suggest the following for adolescent populations: (1) in a very high-risk population, risk factors for future attempts may be more difficult to ascertain and some established risk factors (e.g. past suicide attempt) may not distinguish as well; and (2) cross-cutting constructs (e.g. affective and behavioral dysregulation) that underlie multiple psychiatric disorders may be stronger predictors of recurrent suicide events than psychiatric diagnoses. Our finding with respect to positive affect intensity is novel and may have practical implications for the assessment and treatment of adolescent suicide attempters.

Trajectories of depressive symptoms and externalizing behaviors across adolescence: associations with histories of suicide attempt and ideation in early adulthood

We examined associations between adolescent problem trajectories and suicide risk outcomes in 361 community participants. Depressive symptoms (self-report) and externalizing behaviors (parent report) were assessed six times from grades 5 to 10. Parallel process linear growth curves indicated that lifetime suicide attempt history assessed to age 25 was associated with higher intercept (grade 5) and slope (increases from grades 5 to 10) of depressive symptoms and higher slope of externalizing behaviors. Both problem intercepts predicted suicidal ideation at ages 18 to 25 years. Adolescent depressive and externalizing symptom trajectories showed independent associations with suicide risk. Preventive intervention that occurs prior to the developmental period in which suicidal thoughts and behaviors show peak prevalence is expected to prevent suicide.

Adolescent nonsuicidal self-injury: the effects of personality traits, family relationships and maltreatment on the presence and severity of behaviours

Personality traits, family environment and maltreatment episodes are often associated with nonsuicidal self-injury (NSSI); however, research on these associations has shown mixed results. The aim of the present study was to clarify the effects of these factors on the presence and the severity of NSSI among a sample of Italian students who attended secondary schools (N = 267, mean age = 17.03 SD = 0.866). The results showed that personality traits, family environment and maltreatment differently predicted the presence and the severity of NSSI. Self-injurers were more impulsive and aggressive than non-self-injurers and reported poorer relationship quality with their mothers and more sexual and physical abuse episodes than non-self-injurers. Conversely, the frequency of NSSI behaviours was predicted by the presence of less impulsiveness, more anxiety and aggressiveness, poorer relationship quality with both parents and a lower degree of identification with the father. Finally, more frequent self-injurers also reported more sexual abuses and neglect episodes than less frequent self-injurers.

Suicidal behavior in minors-diagnostic differences between children and adolescents

BACKGROUND

To date, the study of suicidal behavior among minors has focused on the age group in which it is more prevalent: adolescents. We hypothesized that suicidal behavior in children stems from a different diagnosis than suicidal behavior in adolescents, and thus merits its own investigation.

METHOD

We studied all minors (266) who were referred to a psychiatric emergency department due to a suicide attempt or suicidal ideation during a 3-year period.

RESULT

There was an age-related difference in diagnostic distribution among minors who were referred to the emergency department because of suicidal behavior (χ(2) (7) = 24.297, P < 0.01). Attention deficit hyperactivity disorder was more prevalent among children (under 12 years old), whereas mood disorders were more prevalent among adolescents (12-18 years old).

CONCLUSION

The findings of this study highlight a diagnostic difference between suicidal children and suicidal adolescents.

Aggression, impulsivity, and suicide behavior: a review of the literature

This article reviews the literature on the association between impulsivity aggression and suicide. The key words impulsivity, aggression, and suicide were entered into the pubmed, psychlit, and proqest databases. Significant articles were scrutinized for relevant information. Impulsivity and aggression are highly correlated with suicidal behavior across psychiatric samples, nosological borders, and non-psychiatric populations. Impulsivity and aggression are related but the nature of this relationship remains unclear. The literature is confusing and contradictory. This is probably due to the difficulty in defining and separating out these concepts and the fact that there is much overlap between them. Future research should aim at clarifying and refining these concepts as well as their link to all the different forms of suicidal behavior.

Trait anger, anger expression, and suicide attempts among adolescents and young adults: a prospective study

Previous studies of the relationship between anger, anger expression, and suicidal behavior have been largely cross-sectional and have yielded mixed findings. In a prospective, naturalistic study, we examined how trait anger and anger expression influenced the likelihood of suicide attempts among 180 adolescents followed for up to 13.3 years after discharge from an inpatient psychiatry unit. Results showed that higher trait anger and anger expressed outwardly over the follow-up was related to increased likelihood of suicide attempts among boys. For girls, trait anger and both the inward and outward expression of anger moderated the risk for suicide attempts associated with major depression. These results are interpreted in light of theory regarding behavioral activation and behavioral inhibition systems.

Covariation of self- and other-directed aggression among inpatient youth: continuity in the transition to treatment and shared risk factors

Although other- and self-directed aggression covary in very high-risk youth, these forms of aggression infrequently are studied simultaneously. Understanding better their covariation is an important task for improving services to high-risk youth. In this study, data from the clinical records of 476 youth admitted to secure inpatient treatment were analyzed to examine relations among self- and other-directed aggression exhibit before and during inpatient treatment. Analyses tested the hypotheses that self- and other-directed aggression would tend to covary and display continuity from pre-treatment to in-treatment. Also tested were the hypotheses that youth with histories of co-occurring self- and other-directed aggression would show the highest levels of aggression during treatment and the greatest degree of personal and contextual risk on entering treatment. These hypotheses were largely supported. Exploratory analyses revealed interesting discontinuities in aggression (aggression emitted only before or during treatment) with critical implications for research and practice with youth receiving clinical care, especially those in institutional placements.

One-year follow-up of suicidal adolescents: parental history of mental health problems and time to post-hospitalization attempt

This longitudinal study of recently hospitalized suicidal youth examined parental mental health history in addition to several indices of adolescent functioning as risk factors for time-to-suicide attempt over a 1-year period. Participants were 352 adolescents (253 girls, 99 boys; ages 13-17 years) who participated in self-report and interview assessments within 1 week of hospitalization and 6 weeks, 3, 6, and 12 months post-hospitalization. Multivariable proportional hazards regression modeled time-to-suicide attempt. Results indicate that adolescents were almost twice as likely to make a suicide attempt if they had at least one biological parent with mental health problems. Risk was also increased for adolescents with baseline histories of multiple previous suicide attempts, more severe suicidal ideation and more severe functional impairment. Findings suggest the need to consider the family system when intervening with suicidal youth.

Adolescent suicide

PURPOSE OF REVIEW

The present review summarizes the updated literature on adolescent suicide.

RECENT FINDINGS

Reductions in youth suicide rates are probably related to use of selective serotonin reuptake inhibitors since the mid 1990s as well as restrictions in means and enhanced pesticide control. The serotonin theory of suicide has received more empirical support. Familial transmission of suicidal behavior may be mediated by transmission of impulsive aggression from parent to child and early detection of precursors of suicidal behavior can help identify families at high risk of having a suicidal child. A newly investigated social risk factor of bullying adolescents and the novel psychological construct of autobiographical memory all help to advance our understanding and treatment of suicidal youths. Much effort is needed in establishing more solid empirical evidence for suicide prevention programs and treatment, while assessment tools are still in desperate need of further development.

SUMMARY

Suicidal behavior remains an important clinical problem and a major cause of death in youth. There are key issues that need to be solved for better prediction of suicidality, prevention and treatment of youth suicide.
