Adolescent's suicide attempts: populations at risk, vulnerability, and substance use

Potential lethality of suicide attempts in youth

Rates of suicide in youth have increased over the last 50 years, yet our ability to predict suicidal behaviours has not significantly improved during this time. Examining predictors of suicide attempt lethality can enhance our understanding of suicidality in youth, yet research has focused on actual medical lethality (the actual danger to life resulting from a suicide attempt) rather than potential lethality (the potential for death that is associated with a suicide attempt). Thus, the aim of the present study was twofold: first, we quantified the percentage of youth for whom the severity of suicide attempt was misclassified by considering only actual lethality; second, we tested whether key variables that predict the actual lethality of suicide attempts also predict the potential lethality of suicide attempts in youth. We examined these questions in a sample of children and adolescents admitted to a psychiatric inpatient unit following a suicide attempt. Over 70% of youth who made serious suicide attempts would have been misclassified by assessments relying on only actual lethality. Although several variables relevant to the construct of actual lethality significantly predicted potential lethality (e.g., male sex, substance use disorder), others did not. In addition, we found that the subset of youth who would have been misclassified as low risk based on actual lethality had a disproportionately high need for healthcare resources due to future hospital admissions. The present study provides evidence to suggest that considering potential lethality may lead to improved detection and prediction of suicide risk in youth, and in doing so supports recent calls to broaden considerations of the lethality associated with suicide attempts.

Examining differences in suicidality between and within mental health disorders and sexual identity among adults in the United States

BACKGROUND

Suicide is a leading but preventable cause of death and is preceded by domains of thoughts, plans, and attempts. We assessed the prevalence of suicidality domains and determined the association of suicidality domains with sexual identity, mental health disorder symptoms, and sociodemographic characteristics.

METHODS

We used the 2019 National Survey on Drug Use and Health (NSDUH) data to perform weighted multivariable logistic regression and margins analyses to examine between and within-group differences in suicidality by sexual identity among adults aged ≥ 18 years.

RESULTS

About 4.89%, 1.37%, and 0.56% of the population experienced suicidal thoughts, plans, and attempts, respectively. Those aged 18-25 years old had a higher odds of suicidality compared to those aged 26 years or older. Compared to those who reported having no alcohol use dependence, illicit drug use dependence, and major depressive episodes (MDEs), those who reported alcohol use dependence, illicit drug use dependence, and MDE had higher odds of suicidal thoughts, plans, and attempts. Between all sexual identity groups, bisexuals who experienced MDEs had the highest probability of having suicidal thoughts while lesbians and gays who experienced MDE showed a higher probability of suicidal plans and attempts compared to heterosexuals. Within each sexual identity group, the probability of having suicidal thoughts, suicidal plans, and suicidal attempts was higher for those who had experienced MDEs compared to those who had not experienced MDEs.

CONCLUSION

Substance use disorder and MDE symptoms were associated with increased suicidality, especially among young adults and sexual minority people. This disparity underscores the need for tailored interventions and policies to enhance the provision of prompt mental health screening, diagnosis, and linkage to care for mental health services, particularly among the most vulnerable in the population.

Impact of an online depression prevention intervention on suicide risk factors for adolescents and young adults

BACKGROUND

Adolescent death by suicide is an emergent health crisis in the United States of America. Although many suicide prevention programs have been created to address suicide in this population, rates continue to increase. Online interventions can disseminate treatments world-wide and reach large numbers of users. Thus, the purpose of the present study was to determine the effects of CATCH-IT, an Internet-based depression prevention intervention on risk factors for suicide (i.e., suicidal ideation, hopelessness, low self-esteem and social isolation).

METHODS

A total of 83 participants aged 14-21 years [mean =17.5; standard deviation (SD) =2.04] consented to take part in the intervention study.

RESULTS

Results indicated that suicidal ideation decreased from baseline to post-intervention. For those who completed the entire CATCH-IT program, the effect size was moderate (d =0.60, P<0.05). For those who partially completed the program the effect size was small (d =0.22, P<0.05). Interestingly, scales measuring hopelessness and social isolation were not associated with changes in suicidal ideation.

CONCLUSIONS

The findings provide initial evidence that online depression prevention programs could be related to decreased suicidal ideation, and that those who complete the entire program may benefit more than those who complete only a part of CATCH-IT.

Testing a Theory-Based Model of Suicidality in a Community Sample

The aim of the present study is to test a theory-based model of suicide in a low-risk nonclinical sample. A community sample of convenience of 200 adults, 102 men and 98 women, responded to the Depressive Experiences Questionnaire, the Center for the Epidemiologic Studies of Depression Scale, the Psychache Scale, the Interpersonal Needs Questionnaire, and the Suicide Behaviors Questionnaire Revised. The hypothesized structural equation model, including trait dimensions of self-criticism and neediness, and state dimensions of depression, psychache, perceived burdensomeness, and thwarted belongingness, fit the observed data well and significantly explained 49% of the variance of suicidality.

Personality vulnerabilities in adolescent suicidality: The mediating role of psychological distress

The research literature consistently indicates that self-criticism is related to suicidality. Evidence for the role of dependency, however, is more controversial. This study examines the extent to which these personality vulnerabilities are mediated by psychological distress in the prediction of suicidality. As part of a study of adolescent psychopathology, a sample of 260 Portuguese adolescents (148 [56.9 %] female and 112 [43.1%] male), ranging in age from 15 to 18 years (M = 16.32, SD = 1.19) completed measures of personality, suicidal behavior, and current distress, in counterbalanced order. The measures were: self-criticism and dependency from the Depressive Experiences Questionnaire for Adolescents; two psychological distress scales, social withdrawal from the Youth Self Report and depression from the Center for Epidemiologic Studies of Depression Scale; and a measure of suicidality from the Suicide Behaviors Questionnaire Revised. Structural equation modeling indicated that self-criticism and dependency were both significantly associated with suicidality. Psychological distress, however, as measured by withdrawal and depression, fully mediated these relationships, but did not moderate them. The authors conclude that adolescents with higher levels of self-criticism and dependency are at greater risk for experiencing intense psychological distress-high levels of social withdrawal and depression-that account for their vulnerability to suicide risk.

Testing Models Relating Rejection, Depression, Interpersonal Needs, and Psychache to Suicide Risk in Nonclinical Individuals

OBJECTIVES

Using structural equation modeling, we tested a primary model of suicide risk and 3 competing, alternative models based on 4 psychological variables deemed important in the literature (perception of parental rejection, depression, interpersonal needs comprising perceived burdensomeness and thwarted belongingness, and psychache), in a nonclinical sample of Portuguese adults.

METHOD

A convenience sample of 203 adults (100 men, 103 women; aged 18-65 years) participated in this study.

RESULTS

Analyses demonstrated that the proposed primary model had the best fit to the observed data. The differences in fit indexes for this model and one of the alternative models, however, were not substantial.

CONCLUSION

Perceived parental rejection related directly to suicide risk and indirectly via depression and interpersonal needs. Depression linked indirectly to suicide risk via interpersonal needs and psychache. Interpersonal needs related directly to suicide risk and indirectly via psychache, which related directly to suicide risk.

Suicidal ideation and distress in family members bereaved by suicide in Portugal

The present study assessed the impact of suicide and distress on suicidal ideation in a sample of 93 Portuguese family members bereaved by suicide. A control community sample of 102 adults also participated. After controlling for educational level, those bereaved by the suicide of a family member were found to have higher levels of suicidal ideation. Forty-two percent of family members had Suicide Ideation Questionnaire scores at or above the cutoff point. General distress, depression, anxiety, and hostility related to suicidal ideation, whereas time since suicide also interacted with general distress and depression in predicting suicidal ideation.

Risk of psychiatric and neurological diseases in patients with workplace mobbing experience in Germany: a retrospective database analysis

Introduction: The number of mobbing experiences recorded has increased during recent years and it has now been established as global phenomenon among the working population. The goal of our study was to analyze the incidence of certain neurologic and psychiatric diseases as a consequence of mobbing as compared with a control group and to examine the possible influence of previous diseases that occurred within one year before the first mobbing documentation on the incidence of mobbing.

Material & methods: We used a large database (IMS^® Disease Analyzer, Germany) to collect data from general practitioners in Germany from 01/2003 until 12/2012. Based on age, gender, and health insurance, patients with experience of mobbing were matched with a control group of patients who had not reported workplace mobbing and who were being treated by the same physicians. At first, diseases that occurred within one year before the bullying experience took place (“index date”) were noted and compared to a control group of similar composition in terms of gender, age, and health insurance. Subsequently, the prevalence of depression, anxiety, somatoform disorders, and sleep disorders following experiences of mobbing were determined. After adjustment to take into account the odds of bullying, the ratios of these diseases were assessed using a logistic regression model.

Results: The study population consisted of n=2,625 patients and n=2,625 controls, of which 33% were men. The number of cases of bullying documented rose continuously from 2003 to 2011 and remained high in 2012. Those who would later become victims of mobbing demonstrated a considerably higher prevalence of diseases in general – these diseases were not confined to the neurologic-psychiatric spectrum. Following experiences of bullying, depression, anxiety, somatoform disorders, and sleep disorders were significantly more prevalent than in the control group (for all, p<0.05). Similarly, odds ratios (OR) representing the risk of suffering from diseases were higher in affected patients, with the highest value (4.28) for depression and the lowest value for sleep disorders (OR=2.4).

Conclusion: Those who will later become the victims of bullying are more prone to suffer from diseases in general, even before this experience of mobbing has occurred, which underlines the importance of supporting (chronically) ill patients to protect them against bullying. Sequelae of mobbing include, in particular, diseases from the neurologic-psychiatric spectrum.

Is parenting style a predictor of suicide attempts in a representative sample of adolescents?

BACKGROUND

Suicidal ideation and suicide attempts are serious but not rare conditions in adolescents. However, there are several research and practical suicide-prevention initiatives that discuss the possibility of preventing serious self-harm. Profound knowledge about risk and protective factors is therefore necessary. The aim of this study is a) to clarify the role of parenting behavior and parenting styles in adolescents' suicide attempts and b) to identify other statistically significant and clinically relevant risk and protective factors for suicide attempts in a representative sample of German adolescents.

METHODS

In the years 2007/2008, a representative written survey of N = 44,610 students in the 9th grade of different school types in Germany was conducted. In this survey, the lifetime prevalence of suicide attempts was investigated as well as potential predictors including parenting behavior. A three-step statistical analysis was carried out: I) As basic model, the association between parenting and suicide attempts was explored via binary logistic regression controlled for age and sex. II) The predictive values of 13 additional potential risk/protective factors were analyzed with single binary logistic regression analyses for each predictor alone. Non-significant predictors were excluded in Step III. III) In a multivariate binary logistic regression analysis, all significant predictor variables from Step II and the parenting styles were included after testing for multicollinearity.

RESULTS

Three parental variables showed a relevant association with suicide attempts in adolescents - (all protective): mother's warmth and father's warmth in childhood and mother's control in adolescence (Step I). In the full model (Step III), Authoritative parenting (protective: OR: .79) and Rejecting-Neglecting parenting (risk: OR: 1.63) were identified as significant predictors (p < .001) for suicidal attempts. Seven further variables were interpreted to be statistically significant and clinically relevant: ADHD, female sex, smoking, Binge Drinking, absenteeism/truancy, migration background, and parental separation events.

CONCLUSIONS

Parenting style does matter. While children of Authoritative parents profit, children of Rejecting-Neglecting parents are put at risk - as we were able to show for suicide attempts in adolescence. Some of the identified risk factors contribute new knowledge and potential areas of intervention for special groups such as migrants or children diagnosed with ADHD.

Cyber bullying and physical bullying in adolescent suicide: the role of violent behavior and substance use

The impact of bullying in all forms on the mental health and safety of adolescents is of particular interest, especially in the wake of new methods of bullying that victimize youths through technology. The current study examined the relationship between victimization from both physical and cyber bullying and adolescent suicidal behavior. Violent behavior, substance use, and unsafe sexual behavior were tested as mediators between two forms of bullying, cyber and physical, and suicidal behavior. Data were taken from a large risk-behavior screening study with a sample of 4,693 public high school students (mean age = 16.11, 47 % female). The study's findings showed that both physical bullying and cyber bullying associated with substance use, violent behavior, unsafe sexual behavior, and suicidal behavior. Substance use, violent behavior, and unsafe sexual behavior also all associated with suicidal behavior. Substance use and violent behavior partially mediated the relationship between both forms of bullying and suicidal behavior. The comparable amount of variance in suicidal behavior accounted for by both cyber bullying and physical bullying underscores the important of further cyber bullying research. The direct association of each risk behavior with suicidal behavior also underscores the importance of reducing risk behaviors. Moreover, the role of violence and substance use as mediating behaviors offers an explanation of how risk behaviors can increase an adolescent's likelihood of suicidal behavior through habituation to physical pain and psychological anxiety.

Substance abuse and suicide risk among adolescents

The aim of this paper was to review the literature concerning the relationship between suicide and substance abuse behaviours among adolescents, focusing on epidemiology, comorbidity and preventive programmes. We performed a Pubmed/Medline, Scopus, PsycLit and PsycInfo search to identify all papers and book chapters during the period between 1980 and 2011. Adolescents with substance abuse disorder who attempt or complete suicide can be characterized as having mood disorders, stressful life events, interpersonal problems, poor social support, lonely lives and feelings of hopelessness. The research supports the existence of a strong relationship between suicide and substance abuse. Preventive programmes should be based on the detection of risk factors associated with both suicide and substance abuse disorder. Management programmes should combine different therapeutic strategies such as peer-to-peer education, school-based programmes, psychotherapy and pharmacological treatment. Evidence suggests that targeted suicide prevention programmes can be delivered which reduce the burden associated with substance abuse and suicide in youths.

Habilidades sociais e abuso de drogas em adolescentes

O presente estudo propõe uma revisão bibliográfica sobre habilidades sociais e abuso de substâncias. Este artigo foi elaborado a partir de pesquisa nas Bases de Dados Pschynfo, Web of Science, Cochrane Library, Proquest, Medline e Lilacs, entre 1996 e 2006. Os descritores foram: social skills, social skills training, social competence, assertiveness, adolescents, teeenagers, substance abuse, drug abuse, cannabis e marijuana. Nas bases de língua portuguesa, foram: habilidades sociais, treinamento em habilidades sociais, assertividade, adolescentes, abuso de substâncias, drogas e maconha. Os estudos, a maioria de língua inglesa, apontaram a existência de déficits, principalmente a dificuldade em resistir às drogas e dizer não. Conclui-se que a construção de habilidades de resistência ao oferecimento de drogas, a auto-eficácia e o estímulo à capacidade de tomada de decisões pode reduzir o uso de substâncias. Poucos estudos brasileiros foram encontrados abordando esta temática.

Psychotherapy in the treatment of alcohol and substance abusing adolescents with suicidal behavior

Adolescence is a unique time period in an individual's life, one in which suicide and substance abuse become substantial health risks. Currently, suicide accounts for approximately 14% of all deaths among 15-24 year olds in the U.S.A. Drug, alcohol abuse and dependence are the most prevalent causes of adolescent morbidity and mortality in the USA. Numerous studies have demonstrated the link between adolescent alcohol, substance abuse and suicide. When compared to community controls, the rate of a substance abuse disorder was 8.5 times higher in a sample of adolescent suicide completers and the rate of alcohol abuse was 7.5 times higher. Genetic and biological variables may also be responsible for either alcohol and substance abuse or suicide or both alcohol and substance abuse and suicide. There is little empirical research evaluating the effectiveness of alcohol and substance abuse treatments for adolescents. Therapies such as multisystemic therapy, functional family therapy, motivational interviewing, community reinforcement, the 12-step approach and contingency management reinforcement seem to be effective treatments. Despite the strong association between adolescent alcohol and substance use and suicidal behaviors, few studies have investigated the combined treatment of these two issues. Cognitive behavioral therapy, particularly dialectical behavior therapy, seems to be a promising psychotherapy treatment for suicidality in alcohol and substance abusing adolescents. Further research is needed to determine the efficacy of various treatments of alcohol and substance abusing adolescents with suicidal behavior.
