Risk Factors for Suicide Attempts among Korean Adolescents

This study examined the rate of suicide attempts and relevant variables and identified risk factors for suicide attempts among Korean adolescents. A cross-sectional study was performed using an anonymous, self-report questionnaire. A total of 2,100 Korean adolescents, including 1,321 student adolescents and 779 delinquent adolescents, were selected using a proportional stratified random sampling method for this study. The results showed the rate of suicide attempts to be 11.6%, with delinquent adolescents reporting a higher rate of suicide attempts than student adolescents. Adolescent suicide attempts indicated higher levels of dysfunctional family dynamics and maladaptive personalities. In addition, adolescents who attempted suicide expressed a significantly lower level of life satisfaction and less effective coping strategies compared with those adolescents who had not attempted suicide. Logistic regression analysis revealed that five predictive risk factors appeared to be statistically significant: coping strategy, parental child-rearing pattern, depression, parent-child relationship, and psychosomatic symptoms, in this order at p < 0.05.

Risk Factors for Suicide Attempts Among Alcohol Dependent Patients

Suicidal behavior is a common and important problem among alcohol dependent patients. The study was designed to examine risk factors for attempting suicide in 499 alcohol dependent patients. Those who had attempted suicide (N = 198) were more likely to be female, report a family history of suicidal behavior, report more childhood trauma, report greater levels of aggressive behavior, began heavy drinking earlier, and were more likely to have received antidepressant medication. Logistic regression analysis showed that gender, family history, and childhood sexual abuse history made significant and independent contributions to the risk of a suicide attempt. Thus, developmental, personality, family history, social, and comorbidity risk factors may differentiate alcohol dependent patients who have attempted suicide from those who have not.     

Age Variability in the Association Between Heavy Episodic Drinking and Adolescent Suicide Attempts: Findings From a Large-Scale,School-Based Screening Program

ObjectiveAlcohol use is a risk factor for suicidal behavior among adolescents, but it is not clear whether this association is consistent during the adolescent period. This study examined the age-specific associations between heavy episodic drinking (HED) and self-reported suicide attempts in a large and diverse sample of adolescents.MethodScreening data from 32,217 students, between the ages of 11 and 19 years, in 225 schools were analyzed. Logistic regression analyses estimating the impact of HED on self-reported suicide attempts in the past year were performed.ResultsHeavy episodic drinking was significantly associated with self-reported suicide attempts (odds ratio 1.78, p < .05) controlling for depressive symptoms. However, there was substantial age variability in this association, with the association between HED and self-reported attempts stronger among younger adolescents. Among youths aged 13 years and younger, those who reported an episode of HED during the past year were roughly 2.6 times more likely to report an attempt than those who did not report HED in the past year, in contrast to 1.2 times among youths aged 18 years and older.ConclusionsHeavy episodic drinking is a clear risk factor for suicidal behavior among younger adolescents, beyond the risk conveyed by depressive symptoms. Further research investigating the bases for increased suicide risk among younger adolescents engaging in HED is warranted. Results provide support to AACAP's practice parameters calling for attention to substance abuse in the assessment of suicide risk and suggest that routine screening for HED by physicians may improve the detection of adolescent suicide risk, particularly among younger adolescents.     

Association Between Exposure to Suicidal Behaviors and Suicide Attempts Among Adolescents: The Moderating Role of Prior Psychiatric Disorders

Theories suggest that adolescents exposed to suicide attempts and/or deaths are at higher risk of attempting suicide, themselves. However, research findings have been mixed, with most studies not accounting for psychiatric vulnerability. We examined past psychiatric diagnosis as a moderator of the association between lifetime exposure to suicide attempts and/or deaths and adolescents’ suicide attempts. Adolescents (N?=?518; 60% female; 45% White), ages 12–21, reported on prior suicide ideation and attempts, and mood, anxiety, and substance use disorders at baseline. Suicide attempts since baseline and exposure to suicidal behaviors were assessed 4–6 years later. Lifetime exposure to family suicide attempts and/or suicide deaths, but not to suicidal behaviors of peers/friends or others, was associated with a suicide attempt at follow-up among those with prior psychiatric disorders. Psychologically vulnerable adolescents may require additional support after exposure to suicidal behaviors of a family member to reduce their risk of attempting suicide.

     

The Interactive Effect of Major Depression and Nonsuicidal Self-Injury on Current Suicide Risk and Lifetime Suicide Attempts

This study examined the main and interactive effects of MDD and lifetime nonsuicidal self-injury (NSSI) on current suicide risk and past suicide attempts. We predicted that individuals with a history of NSSI and current MDD would be at greater suicide risk than those with either risk factor alone. An interaction between lifetime MDD and NSSI was hypothesized for past suicide attempts. 204 substance dependent inpatients completed self-report measures and a diagnostic interview. Patients with both a history of NSSI and current MDD, relative to all other groups, had the greatest suicide risk. No support was found for the lifetime MDD by NSSI interaction. Conclusion: Findings suggest the relevance of both NSSI and MDD in suicide risk.     

Prevalence and Risk Factors Associated with Suicide Ideation and Attempts in Korean College Students

Objective

Suicide is a leading cause of death in college age students. Identification of the associated risk factors has important implications for how to prevent and respond to this population; however, few studies have been performed on this topic in this age group. The purpose of this study was to evaluate the prevalence and risk factors associated with suicide ideation and attempts in college students.

Methods

Three hundred sixty-eight college students participated in this cross-sectional observational study. The recent (over two weeks) suicide ideation and lifetime suicide attempts were defined according to Moscicki''s suicide behavior index. Sociodemographic variables were assessed and psychopathology measured using the Beck Depression Inventory, the Bipolar Spectrum Diagnostic Scale and the Alcohol Use Disorders Identification Test. A hierarchical multiple logistic regression analysis was used to identify the significant risk factors related to suicide ideation and attempts.

Results

The two-week prevalence of suicidal ideation was 9.8%, and the lifetime prevalence of suicide attempts was 3.3%. The univariate analysis showed that students who had more severe depression (p<0.001), a higher probability for bipolar disorder (p<0.001) and decrement of academic achievement (p<0.005) were more likely to have suicide ideation. Those with factors such as severe depression (p<0.05), a higher probability of bipolar disorder (p<0.001), a low socioeconomic status (p<0.001), who lived alone (p<0.01), and were female (p<0.05) had a higher risk for suicide attempts. The most important predictors of suicide ideation, by the logistic regression analysis, were depression, probability for bipolar disorder and academic achievement, and the risks identified for suicide attempts were socioeconomic status and probability of bipolar disorder.

Conclusion

Suicide ideation and attempts were common in college students. The results of this study suggest that early identification and management of mood disorders and other sociodemographic risk factors may have implications for intervention and prevention.     

One-Year Incidence of Suicide Attempts and Associated Risk and Protective Factors Among Adolescents

The goal of this study was to estimate incidence of adolescent suicide attempts and predictors of attempts. Data were collected using diagnostic interviews and questionnaires with a sample of 4,175 youths 11–17 and 3,134 followed-up a year later. Total incidence was 0.95% and first incidence 0.84% for attempts. We found few significant independent predictors of attempts. Multivariate analyses identified only 2 independent predictors of first incidence (marijuana use and caregiver attempts). We did find evidence for cumulative effects of risk factors, with increased odds of attempts with increasing number of risk factors. The difficulty in identifying a common set of modifiable risk factors continues to make development of effective interventions difficult. However, based on our results and those of other researchers, the impact of the cumulative risk conferred by multiple factors would seem to offer a viable strategy for reducing risk of suicide attempts as well as other mental health outcomes among adolescents.     

Emergency Department Screening for Suicide and Mental Health Risk

Suicide is the second leading cause of death among youth ages 10–24. An estimated 1.5 million US adolescents receive their primary health care in the emergency department (ED); this is particularly true for low-income and minority youths who often lack a regular source of care. ED visits can provide a window of opportunity to screen and identify youths with suicide and mental health risk, triage youths based on need, and facilitate effective follow-up care. Recently developed brief therapeutic assessment approaches have demonstrated success in improving rates of follow-up care after discharge from the ED. Furthermore, there is some data supporting clinical benefits when youths receive evidence-based outpatient follow-up care. ED screening combined with effective follow-up, therefore, may provide one strategy for improving mental health and reducing health disparities in our nation. This paper reviews the context in which ED screenings occur, available tools and strategies, and evidence for the effectiveness of tested approaches.     

Childhood Exposure to Psychological Trauma and the Risk of Suicide Attempts: The Modulating Effect of Psychiatric Disorders

ObjectiveWe examined whether childhood exposure to psychological trauma is associated with greater suicidality and whether specific psychiatric disorders modulate this association in a representative sample of Korean adults.MethodsThe Korean version of the Composite International Diagnostic Interview 2.1 was administered to 6,027 subjects aged 18-74 years. Subjects who experienced a traumatic event before the age of 18 years, the childhood-trauma-exposure group, were compared with controls without childhood trauma exposure.ResultsChildhood exposure to psychological trauma was associated with lifetime suicidal ideation (OR=3.19, 95% CI=2.42-4.20), suicide plans (OR=4.15, 95% CI=2.68-6.43), and suicide attempts (OR=4.52, 95% CI=2.97-6.88). These associations weakened after further adjustment for any psychiatric disorders, but they were not eliminated. The risk of suicide attempts related to childhood trauma increased with the presence of a concurrent alcohol use, depressive, or eating disorder.ConclusionIn terms of clinical implications, patients with these disorders who have a history of childhood trauma should be carefully assessed for their suicide risk and aggressively treated for psychiatric disorders.     

Childhood Exposure to Caregiver Suicidal Behavior and Risk for Adult Suicide Attempts: Findings from a National Survey

The objective of this study was to investigate the association between exposure to caregiver suicidality and subsequent adult suicide attempt (SA). Data came from the National Epidemiologic Survey on Alcohol and Related Conditions Wave 2 (n = 34,653). Respondents were asked if they had a caregiver attempt or complete suicide during childhood. Logistic regression examined associations between SA and caregiver suicidality. Compared to individuals with no suicidality, risk for lifetime SA was higher for individuals that were exposed to a SA (15.6%, [OR] = 5.86, 95% [CI] = 4.57–7.51) and for those who experienced a death by suicide (6.1%, [OR] = 2.08, CI = 1.32–3.26]. Associations remained significant after controlling for demographics, Axis I and II disorders and childhood adversity. Individuals with exposure to suicidality are at increased odds for SA.     

Suicide Attempts in 107 Adolescents and Adults with Kleptomania

Suicide attempts in kleptomania have received little investigation. This study examined rates, correlates, and predictors of suicide attempts in kleptomania. A total of 107 adolescent and adult subjects (n = 32 [29.9%] males) with DSM-IV kleptomania were assessed with standard measures of symptom severity, psychiatric comorbidity, and functional impairment. Subjects had high rates of suicide attempts (24.3%). The suicide attempt in 92.3% of those who attempted suicide was attributed specifically to kleptomania. Suicide attempts were associated with current and life-time bipolar disorder (p = .047) and lifetime personality disorder (p = .049). Individuals with kleptomania have high rates of suicide attempts. Bipolar disorder is associated with suicide attempts in individuals with kleptomania and underscores the importance of carefully assessing and monitoring suicidality in patients with kleptomania.     

Pathways to High-Lethality Suicide Attempts in Individuals with Borderline Personality Disorder

The purpose of this study was to develop and test a model of high-lethality suicide attempts (HLSA) in individuals with Borderline Personality Disorder (BPD). An increased number of prior suicide attempts, substance use immediately prior to the attempt, and objective planning were proposed to lead directly to a HLSA, while aggression and impulsivity were hypothesized to lead indirectly to a HLSA through their associations with prior attempts. Path analysis revealed a revised model in which impulsivity was found to be significantly associated with both the lethality of the most recent attempt and the number of prior attempts. These results are discussed in terms of trait and crescendo models of suicidal behavior and their implications for suicide risk assessment among individuals with BPD.     

Self-Harm and Suicide Attempts in Individuals with Bulimia Nervosa

Self-harm has been identified as a clinical feature in at least a subgroup of women with bulimia nervosa. We explored how women with bulimia who engage in self-harming behaviors differ from women with bulimia without self-harming behaviors and from women with bulimia who attempt suicide with lethal intent. We compared features of the eating disorder, Axis I and II comorbidity, and Eating Disorder Inventory and Temperament and Character Inventory (TCI) scores across 19 women with bulimia who engaged in self-harming behaviors, 28 women with bulimia who reported suicide attempts with lethal intent, and 105 women with bulimia with no self-harming or suicidal behaviors. Women with bulimia nervosa and self-harm behaviors reported significantly more laxative abuse and drug abuse in general. Bulimic women with suicide attempts had the highest rates of overall comorbidity across the three groups. Individuals with self-harm scored significantly higher on the self-transcendence scale of the TCI. Bulimic women with self-harming behaviors appear to engage in more drug taking behavior--both associated with the eating disorder (laxatives) and in terms of illicit drug use. Overall, the highest rates of Axis I and Axis II comorbidity were associated with individuals with suicide attempts. High scores on self-transcendence may signal a greater sense of dissociation and disconnectedness in bulimic women who self-harm.     

Clinical Features Associated with Suicide Attempts versus Suicide Gestures in an Inpatient Sample

The objective of this study was to test whether suicide attempters and suicide gesturers can be clinically differentiated. A total of 150 subjects who had attempted suicide at least once, had made a suicide gesture, had suicidal ideation, and/or had engaged in non-suicidal self-injury were recruited from the inpatient service of the Jiménez Díaz Foundation (Madrid, Spain). A multinomial regression analysis was conducted. Histrionic and antisocial personality disorders were risk factors specific to suicide gestures. Narcissistic personality disorder was specifically associated with suicide attempts. Borderline personality disorder was associated with both suicide gestures and attempts. A high level of impulsiveness was a risk factor specific to suicide attempts. Conclusion: Suicide attempters and suicide gesturers are two distinct, although partially overlapping, populations.
