Risk-Taking Behavior and Suicidality: The Unique Role of Adolescent Drug Use

Suicide ideation and psychotropic recreational drug use by adolescents: a systematic review and meta-analysis

BACKGROUND

Adolescence is characterized by complex and dynamic changes, often involving experimentation, including the use of psychotropic substances. Although it is well-established that recreational psychotropic drugs are associated with suicide ideation in adults, evidence of this association in adolescents remains limited.

OBJECTIVE

To investigate the relationship between suicide ideation and psychotropic recreational drug use among adolescents.

DESIGN AND SETTING

Systematic review with meta-analysis developed at Universidade Federal de Uberlândia (UFU) and Universidade Estadual de Campinas (UNICAMP), Brazil.

METHODS

A search across eight electronic databases for observational studies, without language or publication year restrictions, was conducted. The Joanna Briggs Institute tool was used to assess the risk of bias. Random-effects meta-analyses and odds ratios were used to measure the effects.

RESULTS

The search yielded 19,732 studies, of which 78 were included in the qualitative synthesis and 32 in the meta-analysis. The findings indicated that suicidal ideation was 1.96 times more likely (95% confidence interval, CI = 1.47; 2.61) for adolescents who used some drug recurrently and 3.32 times more likely (95%CI = 1.86; 5.93) among those who abused drugs. Additionally, adolescents who used cannabis were 1.57 times more likely (95%CI = 1.34; 1.84) to experience suicide ideation compared with non-users, while cocaine users had 2.57 times higher odds (95%CI = 1.47; 4.50).

CONCLUSIONS

Psychotropic recreational drug use is associated with suicidal ideation among adolescents regardless of current or previous use, abuse, or type of substance used.

Protective behavioral strategies as a protective factor against suicidal ideation among college student drinkers

Objective: Research shows that alcohol use is linked to suicidal ideation (SI), while depression is strongly associated with SI. Protective behavioral strategies (PBS) are safe drinking strategies. PBS are broadly protective across alcohol-related problems; however, it is unclear if these effects extend to those at risk for SI. We hypothesized that alcohol use and depressive symptoms would be risk factors for SI, and that these factors would moderate the effects of PBS. PBS was hypothesized to be protective for individuals with elevated depressive symptoms and alcohol use. Participants: College student drinkers (n = 990; M age = 19.97, SD = 3.75) from a Southeastern University. Methods: Participants completed an online survey inquiring about demographics, depressive symptoms, SI, alcohol use, and PBS use. Results: Depressive symptoms were associated with an increased likelihood of SI; however, alcohol use was not. PBS were most protective for individuals with high levels of alcohol use and/or depressive symptoms. Conclusions: PBS may be protective for heavier drinkers who are at heightened risk for SI.

Does risk-taking or alcohol misuse mediate the association between anger and suicidal ideation in male depression?

Anger is among the core symptoms in male-specific inventories of depression and has consistently been linked with suicidal ideation. In this study, we assessed whether this link may be mediated via other prominent symptoms of depression in men, namely risk-taking and alcohol misuse. We used self-reported data from 322 men responding to a 3-wave survey over 6 months. Regression with mediation analysis was employed to test whether anger at baseline predicted suicidal ideation six months later through the mediating effects of risk-taking or alcohol misuse at 3 months. We found a statistically significant indirect effect (indicating a mediation effect) of anger at baseline on suicidality at 6-months follow-up through risk taking at 3-months follow-up (effect = 0.007, SE = 0.003, 99% Confidence interval = 0.0002 to 0.0161). Anger at baseline was not significantly associated with alcohol misuse at 3-months follow-up (β = .062, t = 0.919, p = .358), thus nullifying alcohol misuse as a possible mediator between anger and suicidal ideation. In conclusion, the results of this study suggest that risk-taking, but not alcohol misuse, may be a mediator between anger and suicidal ideation in the context of male depression. If these results are replicated, assessing anger and risk-taking may inform monitoring of suicidality. Also, anger and risk-taking may be promising targets for treatment aimed at reducing the risk of suicide.

Cumulative Health Vulnerabilities Among Adolescents by Age and Neighborhood Opportunity

BACKGROUND AND OBJECTIVES

Early detection of health vulnerabilities in adolescents is integral to promoting healthy behaviors into adulthood. Our objective was to quantify the prevalence of health vulnerabilities among adolescents and examine differences by age and neighborhood opportunity.

METHODS

In a cross-sectional analysis of electronic health record data for adolescents aged 13 to 18 years with preventive visits in a large pediatric primary care network between September 2021 and September 2022, we examined 5 health vulnerabilities: Tobacco use, substance use, firearm access, condomless intercourse, and depressive symptoms. Health vulnerabilities were assessed via self-reported adolescent health questionnaire and the validated Patient Health Questionnaire-Modified. Prevalence of health vulnerabilities were calculated alone and in combination, and compared by age and by quintile of neighborhood Child Opportunity Index (COI) score. Multivariable logistic regression estimated associations of neighborhood COI with reporting ≥2 health vulnerabilities.

RESULTS

Among 40 197 adolescents (57.7% aged 13-15 years, 66.3% living in "high"/"very high" COI neighborhoods), 29.7% reported at least 1 health vulnerability and 7.9% reported ≥2 vulnerabilities. Cumulative health vulnerabilities were more prevalent among older adolescents and adolescents from lower opportunity neighborhoods. In adjusted models, lower COI was associated with 65% higher odds of having ≥2 vulnerabilities (odds ratio 1.65, 95% confidence interval 1.43-1.91) compared with adolescents from the highest COI quintile.

CONCLUSIONS

Understanding the relationship between health vulnerabilities and neighborhood opportunities among adolescents may allow pediatric primary care providers and health systems to offer more tailored community support services and transdiagnostic specialized care navigation to address the health needs of teens with multiple vulnerabilities.

Correlations between weight perception and overt risk-taking among Canadian adolescents

OBJECTIVE

Perceptions of body weight represent an important health issue for Canadian adolescents. While associations between weight perception and mental health concerns like eating disorder symptomatology are well established, there is need for more Canadian evidence about how weight perception is associated with overt risk-taking among adolescents, and further how such associations differ by biological sex.

METHODS

We conducted a national analysis of grade 9-10 students participating in the 2017-2018 cycle of the Health Behaviour in School-aged Children (HBSC) study in Canada. This analysis described contemporary patterns of alternate weight perception and then examined the strength and statistical significance of such associations by biological sex, with tobacco, alcohol, and cannabis use, binge drinking, fighting, and illicit drug use as outcomes. Behaviours were considered both individually and in combination. Analyses were descriptive and analytical, with regression models accounting for the nested and clustered nature of the sampling approach.

RESULTS

Responses from 2135 males and 2519 females were available for a complete case series analysis. A total of 26% and 35% of males and females, respectively, perceived themselves as "too fat" while 20% and 9% identified as "too thin". Females perceiving themselves as "too fat" reported higher likelihoods of engaging in individual and scaled indicators of overt risk-taking. Conversely, among males, alternate weight perception was associated with lower levels of such behaviours.

CONCLUSION

As males and females perceive and react to weight perception differently, clinical and health promotion strategies should be developed and uniquely targeted to groups of adolescents in regards to weight perception and risk-taking.

Examining the relationship between risky sexual behavior and suicidal thoughts among unmarried adolescents in India

Addressing the problem of suicidal thoughts in adolescents requires understanding the associated risk factors. Multiple studies have shown that risky sexual behavior affected the adolescents' psychological health that leads to their suicidal thoughts, behaviors and attempts. This study aimed to identify the association between various risky sexual behaviours and suicidal thoughts among unmarried adolescents in India. We used data collected from 4221 unmarried adolescent boys and 5987 unmarried adolescent girls aged 10-19 years, from the two rounds of the Understanding the Lives of Adolescents and Young Adults (UDAYA) survey. Descriptive analysis was done to observe changes in the selected variables from wave-1 to wave-2. Random effect regression analysis was used to estimate the association of suicidal thoughts among unmarried adolescents with their risky sexual behaviours. The percentage of adolescent boys having suicidal thoughts increased from 1.35% in wave 1 to 2.19% in wave 2. Among adolescent girls, the percentage increased from 2.92% in wave 1 to 5.05% in wave 2. A proportion of 3.26% adolescent boys had more than one sexual partner during wave 1 whereas in wave 2, it rose to 8.71%, while in case of adolescent girls, the estimates only increased from 0.26% at wave 1 to 0.78% at wave 2. Nearly 4.55% boys and 1.37% girls had early sexual debut. Almost five percentage boys were sexually active at wave 1 whereas in wave 2, it rose to 13.56%, while among adolescent girls, the estimates decreased from 1.54% at wave 1 to 1.51% at wave 2. Contraceptive use increased over time among both adolescent boy and girls. Also, a large proportion of adolescent boys reported watching pornography (27.08% at waive 1 and 49.39% at wave 2) compared to adolescent girls (4.46% at wave 1 and 13.10% at wave 2). Adolescents who had more than one sexual partner [Coef: 0.04; p < 0.001], exposed to early sexual debut [Coef; 0.019; p < 0.01], sexually active [Coef: 0.058; p < 0.001] and reported watching pornography [Coef: 0.017; p < 0.001] were more likely to have suicidal thoughts. Adolescent boys and girls with risky sexual behaviors are likely to be at a higher risk of suicidal ideation, and thus, they should be treated with special care and attention by local healthcare practitioners.

Incidence and risk factors for suicide, death due to substance use, and violent/accidental death in people with HIV

OBJECTIVE

Deaths due to suicide, substance use and violence/accident may reflect similar risk factors and overlap in their classification. This study aimed to investigate incidence and risk factors of mortality among people with HIV (PWH) due to these three related causes.

DESIGN

Prospectively collected data from PWH at least 18 years old and under active follow-up in the EuroSIDA study from 2007 to 2019 were analysed.

METHODS

Cause-specific Cox regression analysis was used to assess risk factors.

RESULTS

A total of 17 881 participants were included, comprising 149 327 person-years of follow-up (PYFU). Forty participants died by suicide {incidence rate [IR] [95% confidence interval (CI)]: 0.3/1000 PYFU (0.2, 0.4)} 93 from substance use [IR (95% CI): 0.6/1000 PYFU (0.5, 0.8)], and 57 by violence/accident [IR (95% CI): 0.4/1000 PYFU (0.3, 0.5)]. An AIDS diagnosis within the last 12 months was associated with nine-fold increased risk of suicide vs. no history of AIDS [adjusted hazard ratio (aHR): 9.06; 95% CI: 2.07, 39.7]. Male gender was associated with double the risk of violent/accidental death (aHR: 2.28; 95% CI: 1.09, 4.78). PWH in Eastern Europe and those who acquired HIV by injection drug use (IDU) demonstrated a greater risk of death due to substance use or violence/accident.

CONCLUSIONS

The association between a recent diagnosis of AIDS and suicide highlights a critical period for intervention. HIV infection acquired through IDU demonstrated an expected relationship with death due to substance use and violent/accidental deaths. Increased risk of death due to substance use and violence/accident in Eastern Europe demands investigation into specific differences that may drive that association.

Suicidal Ideation in the Australian Construction Industry: Prevalence and the Associations of Psychosocial Job Adversity and Adherence to Traditional Masculine Norms

BACKGROUND

Suicide in the Australian Construction Industry (ACI) is a significant issue, however minimal understanding of suicidal ideation prevalence, as well as the potential role psychosocial job adversity and increased adherence to traditional masculine norms may play in its presence, is apparent.

METHOD

A representative sample of Australian men (n = 11,132) were used to create initial understandings of prevalence of suicidal ideation (past two weeks), psychosocial job adversities and level of adherence to traditional masculine norms for the ACI (n = 1721) in comparison to a general population comprised of the remaining employed males from Other Industries (n = 9411). Additionally, due to their reported increased suicide vulnerability investigation of associations between suicidal ideation, psychosocial job adversities and adherence to traditional masculine norms for the ACI were undertaken.

RESULTS

No difference in suicidal ideation prevalence was reported between the ACI and those employed in Other Industries (p > 0.05), however, increased prevalence of psychosocial job adversities (p ≤ 0.001) and adherence to traditional masculine norms (p ≤ 0.001) for the ACI was seen. Significant multivariate associations between suicidal ideation, psychosocial job adversities (OR = 1.79, 95%CI [1.12-2.85]) and two domains of traditional masculine norms, self-reliance (OR = 1.29, 95%CI [1.09-1.51]) and risk-taking (OR = 1.20, 95%CI [1.01-1.41]), were reported.

CONCLUSION

Results suggest need for increased understanding of later stage suicidal trajectory drivers in the ACI. Findings indicate need for prevention group/industry concentration on mitigation of psychosocial job adversities, as well as a more nuanced and increased discussion of the negative role of self-reliance and risk-taking domains of traditional masculine norms may play in ACI suicidal ideation, as opposed to the construct as a whole.

Suicidal Ideation and Risky Behavior are Related through Impulsivity and Low Wish to Live

OBJECTIVE

Numerous studies have found support for the relationship between suicide and risky behavior. However, few studies have examined factors that may help explain the relationship between suicidal ideation (SI) and risky behavior. This preregistered study examined the relationship between SI and risky behavior and whether there is an indirect relationship through hopelessness, impulsivity, and low wish to live. These factors were selected due to their relationships with both SI and risky behavior.

METHODS

Participants recruited from Amazon Mechanical Turk completed measures of SI, risky behavior, hopelessness, impulsivity, and wish to live. Consistent with our preregistered methods, we analyzed data from 180 participants with valid data. Indirect effects were evaluated via bootstrapping with 5000 resamples of the a path x b path product.

RESULTS

Consistent with prior work, we found a significant positive association between SI and frequency of risky behavior (r = .49). We found significant indirect effects of SI on risky behavior through impulsivity and wish to live but not through hopelessness.

CONCLUSION

SI and risky behavior are associated with each other through impulsivity and wish to live. Though future longitudinal research is needed to determine causality, this has important implications for models of suicidal thoughts and behaviors and their relationship with risky behavior. The potential of future orientation to explain the results is discussed.

Suicidal Depression in Ancient Egypt

OBJECTIVE

To evaluate the oldest record of a depressed individual contemplating suicide.

METHOD

A directed review of ancient Egyptology literature of translations and discussion regarding a papyrus that is approximately 4,000 years old.

RESULTS

The content of the document is consistent with a man going through a severe depression and is contemplating suicide. However, this does not appear to be a suicide note, but more of an ancient example of 'journaling' or working through the thoughts of suicide and its possible consequences to the man's eternal life in the afterworld.

CONCLUSIONS

Presentation of depression, the reasons for considering suicide, and the process by which an individual works through those thoughts have not varied significantly over the past 4,000 years.

COVID-19-Specific Suicidal Thoughts and Behaviors in Psychiatrically Hospitalized Adolescents

This study examined the presence and correlates of COVID-specific suicidal thoughts and behaviors (i.e., thoughts of or engaging in intentional COVID-19 exposure with associated suicidal intent) among psychiatrically hospitalized adolescents. Adolescents (N = 143) completed study measures as part of the standard intake process between March 13th and August 14th, 2020. Participants answered questionnaires assessing COVID-specific passive and active suicidal ideation (SI) and suicidal behavior, as well as COVID-related stressors and emotions, and public health guidance compliance. Findings highlights that COVID-specific SI is common in high-risk youth. COVID-specific SI was associated with COVID-19-related negative emotions, elevated stress, and decreased public health guidance compliance. Results suggest that COVID-specific suicidal thoughts and behaviors, and risk correlates, should be assessed within high-risk populations to facilitate prevention of risky behavior associated with intentional COVID-19 exposure.

Genetic propensity for risky behavior and depression and risk of lifetime suicide attempt among urban African Americans in adolescence and young adulthood

Suicide attempts (SA) among African Americans have increased at a greater rate than any other racial/ethnic group. Research in European ancestry populations has indicated that SA are genetically influenced; however, less is known about the genetic contributors that underpin SA among African Americans. We examined whether genetic propensity for depression and risky behaviors (assessed via polygenic risk scores; PRS) independently and jointly are associated with SA among urban, African Americans and whether sex differences exist in these relations. Participants (N = 1,157, 45.0% male) were originally recruited as part of two first grade universal school-based prevention trials. Participants reported in adolescence and young adulthood on whether they ever attempted suicide in their life. Depression and risky behaviors PRS were created based on large-scale genome-wide association studies conducted by Howard et al. (2019) and Karlson Línner et al. (2019), respectively. There was a significant interaction between the risky behavior PRS and depression PRS such that the combination of high risky behavior polygenic risk and low/moderate polygenic risk for depression was associated with greater risk for lifetime SA among the whole sample and African American males specifically. In addition, the risky behavior PRS was significantly positively associated with lifetime SA among African American males. These findings provide preliminary evidence regarding the importance of examining risky behavior and depression polygenic risk in relation to SA among African Americans, though replication of our findings in other African American samples is needed.

Applying ideation-to-action theories to predict suicidal behavior among adolescents

BACKGROUND

Although many risk factors for adolescent suicidal behavior have been identified, less is known about distinct risk factors associated with the progression from suicide ideation to attempts. Based on theories grounded in the ideation-to-action framework, we used structural equation modeling to examine risk and protective factors associated with the escalation from suicide ideation to attempts in adolescents.

METHODS

In this cross-sectional study, data from the 2013 and 2015 Hawaii High School Youth Risk Behavior Surveys (N = 8,113) were analyzed. The sample was 54.0% female and racially/ethnically diverse. Risk factors included depression, victimization, self-harm, violent behavior, disinhibition, and hard substance use, and protective factors included adult support, sports participation, academic achievement and school safety.

RESULTS

One in 6 adolescents (16.4%) reported suicide ideation, and nearly 1 in 10 (9.8%) adolescents had made a suicide attempt. Overall, disinhibition predicted the escalation to attempts among adolescents with suicide ideation, and higher academic performance was associated with lower suicide attempt risk. Depression and victimization were associated with suicide ideation.

LIMITATIONS

This study examined data from the Youth Risk Behavior Survey, and other known risk factors such as anxiety and family history of suicide were not available in these data.

CONCLUSIONS

Findings provide guidance for targets for clinical interventions focused on suicide prevention. Programs that incorporate behavioral disinhibition may have the greatest potential for reducing suicide attempt risk in adolescents with suicidal thoughts.

The Relationships Between Risk-Taking, Depression, and Alcohol Use in the Experience of Suicidal Ideation Among Adults in the General Population

Risk-taking is associated with suicide among depressed adolescents. In the United States, alcohol is among the most used substances resulting in need for treatment. While alcohol use relates to greater depression and suicidality, less is known about these relationships with risk-taking tendencies, particularly among adult populations. The current study examined suicidal ideation, alcohol use, depression, and risk-taking tendencies among adults 18-65 years old who participated in the 2017 National Survey on Drug Use and Health. Structural equation modeling was used to examine the specific aims in Mplus8. A total of 1,740 (21.4%) participants endorsed suicidal ideation. The model demonstrated good fit and findings indicate increases in alcohol abuse or dependence (b = 0.094, SE = 0.01, p < .001), depression (b = 0.036, SE = 0.01, p < .001), and risk-taking (b = 0.044, SE = 0.01, p < .001) all independently related to increased odds of ideation. Increases in alcohol abuse or dependence (b = 0.210, SE = 0.02, p < .001) and depression (b = 0.026, SE = 0.01, p < .05) also related to elevated risk-taking. Based on the joint significance test, risk-taking tendencies served as a partial mediator, functioning as a mechanism in the relationships between alcohol use, depression, and ideation. Risk-taking thus serves as an important treatment target in the prevention of suicide. Implications for practice and future research are discussed.

Association between Early Spermarche and Suicide Attempts in Boys: the Korea Youth Risk Behavior Web-based Survey

BACKGROUND

Puberty is a biologically and psychologically unstable period, and pubertal changes differ by sex. However, most previous studies on pubertal timing and suicide have focused on girls. This study investigated the association between early spermarche and suicide attempts in boys.

METHODS

We analyzed a nationally representative sample of Korean adolescents (The Korea Youth Risk Behavior Web-Based Survey, KYRBS) that included approximately 35,000 boys annually from 2011 to 2015. Pubertal timing in boys was defined by spermarche. Complex sampling logistic regression analyses were performed to evaluate the odds ratios (ORs) for suicide attempts between the early and average spermarche groups.

RESULTS

The ORs for suicide attempts in boys with early spermarche were significantly higher than those in boys with average spermarche after adjustment for age, perceived stress, depressive symptoms, and suicidal ideation. The ORs from 2011 to 2015 were as follows: 1.782 (P < 0.001), 1.490 (P = 0.002), 1.693 (P < 0.001), 1.541 (P = 0.001), and 1.393 (1.024-1.895; P = 0.035), respectively.

CONCLUSION

These findings suggest that early pubertal timing is a risk factor for suicide attempts in Korean boys after adjustment for depressive symptoms, perceived stress, and suicidal ideation, which have been previously reported as risk factors for suicide attempts. Therefore, careful attention should be paid to the prevention of suicide in boys who experience early spermarche in Korea.

Unintentional injury fatalities in the context of rising U.S. suicide rates: A five-year review of the web-based injury statistics query and reporting system

This archival study focuses specifically on suicide fatalities in relation to unintentional and undetermined injury fatalities in an effort to determine whether or not these rates are rising consistently. This question may serve to inform whether or not suicides are being accurately reported and documented. Data from all 50 states from the years 2012-2016 were obtained from the Web-based Injury Statistics Query and Reporting System (WISQARS) developed by the Centers for Disease Control and Prevention. A total of 213,726 suicide fatalities, 702,176 unintentional injury fatalities, and 24,533 undetermined injury fatalities comprised the dataset. Injury fatality rates depicted annual increases in both suicide and unintentional injury fatalities but variability in undetermined injury fatalities. Bivariate analyses discovered a statistically significant association between annual suicide fatality rates and unintentional (nonsuicidal) injury fatality rates. It would be suspected, ceteris paribus, that calculated rate changes over these years would follow suit. However, this was not observed. Given the trends and increasing stigma surrounding suicide, it is worth considering the degree to which suicides may be underreported or -documented and the epidemiological and translational ramifications of these trends as they pertain to future suicide research.

Annual Research Review: A meta-analytic review of worldwide suicide rates in adolescents

Suicide is a leading cause of death among youth worldwide. The purpose of the current review was to examine recent cross-national trends in suicide mortality rates among 10- to 19-year-olds. This study extracted suicide mortality data from the World Health Organization's (WHO) Mortality Database for the most recent year (since 2010) from any country with available high-quality data (as defined by the WHO's guidelines). Data on access to lethal means (firearms, railways) and measures of economic quality (World Bank Income Group) and inequality (Gini coefficients) were obtained from publicly available data sources. Cross-national suicide mortality rates in youth were heterogeneous. The pooled estimate across all ages, sexes, and countries was 3.77/100,000 people. The highest suicide rates were found in Estonia, New Zealand, and Uzbekistan. Suicide rates were higher among older compared with younger adolescents and higher among males than females. The most common suicide methods were hanging/suffocation and jumping/lying in front of a moving object or jumping from a height. Firearm and railway access were related to suicide deaths by firearms and jumping/lying, respectively. Economic quality and inequality were not related to overall suicide mortality rates. However, economic inequality was correlated with a higher ratio of male:female suicides. This study provides a recent update of cross-national suicide trends in adolescents. Findings replicate prior patterns related to age, sex, geographic region, and common suicide methods. New to this review are findings relating suicide method accessibility to suicide mortality rates and the significant association between income inequality and the ratio of male:female suicide. Future research directions include expanding the worldwide coverage to more low- and middle-income countries, examining demographic groupings beyond binary sex and to race/ethnicity within countries, and clarifying factors that account for cross-national differences in suicide trends.

Effects of self-injurious thoughts and behaviors and sexual risk-taking behaviors through emotional control

BACKGROUND

College students are at increased risk for self-injurious thoughts and behaviors (SITB) and sexual risk behaviors (SRB). Although students with a history of SITB appear to be more prone to SRB, the mechanisms linking these risk behaviors remain largely unexplored. Previous research points to emotional control (EC), defined as one's awareness and adaptability of emotions, as a potential mechanism explaining the relationship between SITB and SRB.1 METHODS: Data included 722 college students attending two different universities in the northeast and southeast regions of the United States. Multiple group structural equation models were fit to estimate the direct and indirect effects of history of SITB (suicidal ideation, attempt, and nonsuicidal self-injury) and EC on SRB jointly across men and women.

RESULTS

Findings supported indirect relationships between SITB and SRB through dysregulated EC, with type of SITB and patterns of SRB differing between men and women. For women, history of suicidal ideation and nonsuicidal self-injury were indirectly related to increased SRB through dysregulated EC. For men, history of suicidal ideation showed an indirect relationship on SRB through EC.

LIMITATIONS

Although this study employed random sampling, limitations include a cross-sectional design, which does not allow for causal inference, and reliance on self-report assessment data.

CONCLUSIONS

College students with a history of SITB who experience dysregulated EC may be more likely to engage in risky sexual behavior. Clinicians working with college students should concomitantly consider suicide and self-injury with SRB and consider interventions to improve EC.

Risk factors for the transition from suicide ideation to suicide attempt: Results from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS)

Prior research has shown that most known risk factors for suicide attempts in the general population actually predict suicide ideation rather than attempts among ideators. Yet clinical interest in predicting suicide attempts often involves the evaluation of risk among patients with ideation. We examined a number of characteristics of suicidal thoughts hypothesized to predict incident attempts in a retrospective analysis of lifetime ideators (N = 3,916) drawn from a large (N = 29,982), representative sample of United States Army soldiers. The most powerful predictors of first nonfatal lifetime suicide attempt in a multivariate model controlling for previously known predictors (e.g., demographics, mental disorders) were: recent onset of ideation, presence and recent onset of a suicide plan, low controllability of suicidal thoughts, extreme risk-taking or "tempting fate," and failure to answer questions about the characteristics of one's suicidal thoughts. A predictive model using these risk factors had strong accuracy (area under the curve [AUC] = .93), with 66.2% of all incident suicide attempts occurring among the 5% of soldiers with highest composite predicted risk. This high concentration of risk in this retrospective study suggests that a useful clinical decision support model could be constructed from prospective data to identify those with highest risk of subsequent suicide attempt.

Risk-taking behaviors and stressors differentially predict suicidal preparation, non-fatal suicide attempts, and suicide deaths

Negative life events are elevated in suicidal populations. Diathesis-stress and kindling effects models suggest different mechanisms by which negative life events increase suicide risk. Different forms of negative life events - risk-taking behaviors and stressors - may have different effects on non-fatal suicide attempts and suicide. We assessed the effects of risk-taking behaviors and stressors on suicide, history of non-fatal suicide attempts, and active preparation for suicide in a sample of adults who died by suicide or other causes (N = 377). Psychological autopsy procedures using family member interviews and collateral record review were used to complete a risk-taking behaviors composite measure from the Structured Interview for DSM-IV Personality Disorders, the Modified Life Experiences Scale, and the planning subscale of the Suicide Intent Scale. Stressors were significantly associated with death by suicide, even when accounting for demographic and diagnostic characteristics. Risk-taking behaviors were significantly associated with non-fatal suicide attempts, even when accounting for demographic and diagnostic characteristics. Suicide decedents who did not actively prepare for suicide showed significantly higher risk-taking scores than suicide decedents who actively planned for suicide. Our results suggest that risk-taking behaviors and stressors impact suicide risk through separate mechanisms. Risk-taking behaviors may represent a longstanding vulnerability to act impulsively on suicidal thoughts. Stressors may impact risk for fatal suicidal behaviors in mood disordered populations.

Emerging trends in adolescent suicide prevention research

A comprehensive public health strategy for adolescent suicide prevention includes upstream prevention strategies, strategies for risk recognition, and services for those at risk. Interpersonal trauma and substance use are important prevention targets as each is associated with risk for suicide attempts. Multiple prevention programs target these factors; however, the Family Check-Up, designed to reduce substance use and behavioral problems, also has been associated with reduced suicide risk. Several youth screening instruments have shown utility, and a large-scale trial is underway to develop a computerized adaptive screen. Similarly, several types of psychotherapy have shown promise, and sufficiently powered studies are underway to provide more definitive results. The climbing youth suicide rate warrants an urgent, concerted effort to develop and implement effective prevention strategies.
