Predictors Of Future Suicide Attempt Research Articles

Management of suicidal risk in the emergency department: A clinical pathway using the computerized adaptive screen for suicidal youth.

Given the critical need for efficient and tailored suicide screening for youth presenting in the emergency department (ED), this study establishes validated screening score thresholds for the Computerized Adaptive Screen for Suicidal Youth (CASSY) and presents an example of a suicide risk classification pathway. Participants were primarily from the Study One derivation cohort of the Emergency Department Screen for Teens at Risk for Suicide (ED-STARS) enrolled in collaboration with Pediatric Emergency Care Applied Research Networks (PECARN). CASSY scores corresponded to the predicted probabilities of a suicide attempt in the next 3 months and risk thresholds were classified as minimal (<1%), low (1%-5%), moderate (5%-10%), and high (>10%). CASSY scores were compared to risk thresholds derived from clinical consensus and ED complaints and dispositions. CASSY risk thresholds were also examined as predictors of future suicide attempts in the Study Two validation cohort of ED-STARS. A total of 1452 teens were enrolled with a median age of 15.2 years, 59.5% were female, 55.6% were White, 22% were Black, 22.3% were Latinx, and 42.8% received public assistance. The clinical consensus suicide risk groups were strongly associated with the CASSY-predicted risk thresholds. Suicide attempts in the Study Two cohort occurred at a frequency consistent with the CASSY-predicted thresholds. The CASSY can be a valuable tool in providing patient-specific risk probabilities for a suicide attempt at 3 months and tailor the threshold cutoffs based on the availability of local mental health resources. We give an example of a clinical risk pathway, which should include segmentation of the ED population by medical versus psychiatric chief complaint.

Predictors of future suicide attempts in individuals with high suicide risk admitted to an acute psychiatry suicide intervention unit in India. A survival analysis study.

Determination of suicide vulnerability remains challenging in mental illness. Variability in risk factors identified compound its poor predictability. Longitudinal studies, offering more reliable indices of risk, from developing countries are conspicuously limited. Furthermore, research advances allude to inherent vulnerability. This study, the first of its kind from India, consequently aimed to delineate factors influencing subsequent attempts in mental illness and acute suicidality. Baseline and follow-up information (up to five years) was obtained from medical records of individuals (n=130) with acute suicidality [recent attempt (first attempt/ reattempt) and high-risk ideators]. Variables were compared between individuals with, and without subsequent suicide attempts. Time to attempt and factors influencing the same was determined using survival analysis, and Cox proportional hazard for estimating the likelihood of a subsequent suicide attempt. Median duration of follow up of the sample (n=130) was 23 months. The sample comprised of individuals with a recent attempt (first-time attempt), recent reattempt and recent high-risk ideators. Subsequent suicide attempts were noted in 30 (23.1%) patients. Baseline sociodemographic and clinical variables, including suicidality, could not differentiate individuals with a subsequent suicide attempt. Survival analysis indicated that 65% of subsequent attempts occurred within 9 months of discharge. Family history of suicide and the presence of impulsive-aggressive traits were associated with both, reduced survival time and overall increased risk of a subsequent suicide attempt. This study delineates both, the time frame associated with greatest risk, as well as individuals most likely to reattempt suicide. It thereby offers insights into potential windows of opportunity to mitigate prospective suicide risk. Strategies such as enhanced after-care and integrating specific interventions to attenuate impulsive-aggressive behaviors could be a focus to prevent future attempts, thereby decreasing rates of suicide amongst those with mental illness. Furthermore, the findings of this study reaffirm the role of factors that independently confer vulnerability to suicide. Traversing noted regional variations, the findings importantlyreinforce the distinct pathophysiological underpinnings of suicide in mental illness.

Suicidality and Alcohol Use as Predictors of Future Suicidal Behavior in College Students.

There has been a marked increase in suicide fatalities among college-age students in recent years. Moreover, heavy alcohol use, a well-known risk factor for suicide, is present on most campuses. Yet, no prospective studies have examined alcohol use patterns among college students as predictors of suicidal behaviors. Online of 40,335 students at four universities took place at the beginning of four academic years, 2015-2018. Of these, 2296 met criteria for an increased risk of suicidal behavior and completed 1- and/or 6-month follow-up evaluation(s). Baseline assessments included the Alcohol Use Disorders Identification Test to quantify alcohol consumption and resulting problems, and measures of depression, suicidal ideation and suicidal behavior. Suicide attempts during follow-up were reported by 35 (1.5%) of high-risk students. Regression analyses indicated that baseline severity of alcohol use consequences, but not amount of alcohol consumption, was associated with greater odds of a follow-up suicide attempt after controlling for baseline suicidal ideation, functional impairment and history of suicide attempts. Among college students at elevated risk for suicide, the severity of alcohol-related consequences was a significant predictor of future suicide attempts. Alcohol consumption was not a significant predictor, suggesting that the amount students drink is less of a concern for suicidal behavior than are the problems (e.g. failing to meet expectations, experiencing blackouts) associated with drinking.

Development and validation of the Durham Risk Score for estimating suicide attempt risk: A prospective cohort analysis.

BackgroundWorldwide, nearly 800,000 individuals die by suicide each year; however, longitudinal prediction of suicide attempts remains a major challenge within the field of psychiatry. The objective of the present research was to develop and evaluate an evidence-based suicide attempt risk checklist [i.e., the Durham Risk Score (DRS)] to aid clinicians in the identification of individuals at risk for attempting suicide in the future.Methods and findingsThree prospective cohort studies, including a population-based study from the United States [i.e., the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) study] as well as 2 smaller US veteran cohorts [i.e., the Assessing and Reducing Post-Deployment Violence Risk (REHAB) and the Veterans After-Discharge Longitudinal Registry (VALOR) studies], were used to develop and validate the DRS. From a total sample size of 35,654 participants, 17,630 participants were selected to develop the checklist, whereas the remaining participants (N = 18,024) were used to validate it. The main outcome measure was future suicide attempts (i.e., actual suicide attempts that occurred after the baseline assessment during the 1- to 3-year follow-up period). Measure development began with a review of the extant literature to identify potential variables that had substantial empirical support as longitudinal predictors of suicide attempts and deaths. Next, receiver operating characteristic (ROC) curve analysis was utilized to identify variables from the literature review that uniquely contributed to the longitudinal prediction of suicide attempts in the development cohorts. We observed that the DRS was a robust prospective predictor of future suicide attempts in both the combined development (area under the curve [AUC] = 0.91) and validation (AUC = 0.92) cohorts. A concentration of risk analysis found that across all 35,654 participants, 82% of prospective suicide attempts occurred among individuals in the top 15% of DRS scores, whereas 27% occurred in the top 1%. The DRS also performed well among important subgroups, including women (AUC = 0.91), men (AUC = 0.93), Black (AUC = 0.92), White (AUC = 0.93), Hispanic (AUC = 0.89), veterans (AUC = 0.91), lower-income individuals (AUC = 0.90), younger adults (AUC = 0.88), and lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) individuals (AUC = 0.88). The primary limitation of the present study was its its reliance on secondary data analyses to develop and validate the risk score.ConclusionsIn this study, we observed that the DRS was a strong predictor of future suicide attempts in both the combined development (AUC = 0.91) and validation (AUC = 0.92) cohorts. It also demonstrated good utility in many important subgroups, including women, men, Black, White, Hispanic, veterans, lower-income individuals, younger adults, and LGBTQ individuals. We further observed that 82% of prospective suicide attempts occurred among individuals in the top 15% of DRS scores, whereas 27% occurred in the top 1%. Taken together, these findings suggest that the DRS represents a significant advancement in suicide risk prediction over traditional clinical assessment approaches. While more work is needed to independently validate the DRS in prospective studies and to identify the optimal methods to assess the constructs used to calculate the score, our findings suggest that the DRS is a promising new tool that has the potential to significantly enhance clinicians’ ability to identify individuals at risk for attempting suicide in the future.

Exploring Lived Experiences of Adolescents Presenting with Self-Harm and Their Views about Suicide Prevention Strategies: A Qualitative Approach.

Suicide is a serious global public health problem and the third leading cause of death in those 15–35 years old. Self-harm is the major predictor of future suicide attempts and completed suicide yet remains poorly understood. There is limited evidence on effective interventions for adolescents who present with self-harm. To identify and develop acceptable preventive and therapeutic interventions it is essential to understand the factors that contribute to self-harm and suicide in young people, in the context of their emotions, interpersonal difficulties, available support and prevention strategies. This qualitative study aimed at exploring the lived experiences of adolescents presenting with self-harm and their views about potential prevention strategies. Semi-structured interviews with 16 adolescents (12–18 years) presenting with a self-harm episode in a public hospital in Pakistan. A topic guide was developed to facilitate the interviews. The following themes emerged using the framework analysis; predisposing factors (interpersonal conflicts, emotional crisis etc.), regret and realization that self-harm is not the only option, perceived impact of self-harm, and suggestions for suicide prevention strategies (sharing, distraction techniques, involvement of family). This study may help in refining a contextual and culturally based explanatory model of self-harm in adolescents and in informing development of culturally acceptable interventions.

Polyunsaturated fatty acids as predictors of future suicide attempt

Polyunsaturated fatty acids (PUFAs) and cholesterol are lipids implicated in suicide risk. We prospectively studied plasma glycerophospholipid PUFAs and cholesterol as putative predictors of suicide attempts. In a multicenter cohort study, we enrolled 123 patients admitted to the emergency department (ED) for suicidal ideation or suicide attempt. Clinical assessments were performed, with follow-up telephone evaluations 6, 12, 18, and 24 months later. Blood samples were obtained in the ED and assayed for PUFAs. Using survival analysis, suicide events were not predicted by eicosapentaenoic acid (EPA, HR: -0.83, 95%CI: 0.39–1.76, p = 0.621) or docosahexaenoic acid (DHA, HR: -0.60, 95%CI: 0.19–1.86, p = 0.371). However, higher arachidonic acid (AA) was a trend for a protective factor (HR=0.30, 95%CI: 0.08–1.08, p = 0.065) in the entire trans-diagnostic sample. This protective effect was significant in all participants with a prior suicide attempt history (n = 85; HR=0.16, 95%CI: 0.04–0.67, p = 0.012), and in the subgroup of attempters with major depressive disorder (MDD; n = 55, HR=0.15, 95%CI:0.03–0.76, p = 0.002). Total LDL- and HDL-cholesterol did not predict subsequent suicide events. AA, but not DHA or EPA, positively correlated with baseline depression severity in MDD patients (r = 0.3, p = 0.006). Contrary to our hypothesis that low n-3 PUFA levels would create risk, we found that while higher AA was associated with greater depression severity at baseline, low AA unexpectedly predicted subsequent suicide attempts, the more so in higher-risk patients. Although surprising, this result agrees with a minority of reports concerning n-6 PUFAs and may represent complex interactions with sample characteristics.

Characteristics of a First Suicide Attempt that Distinguish Between Adolescents Who Make Single Versus Multiple Attempts

Although a history of a suicide attempt is the strongest predictor of future suicide attempts, not all adolescents who make an attempt engage in repetitive suicidal behavior. The present study sought to determine whether certain characteristics of a first suicide attempt (e.g., age of first attempt, method of attempt used, intent seriousness, medical lethality, and receipt of treatment after attempt) can distinguish between adolescents who make single versus multiple suicide attempts. Adolescents (N = 95) who were psychiatrically hospitalized and their guardian completed a diagnostic interview to gather information on all lifetime suicide attempts. A multivariate hierarchical logistic regression was conducted, predicting single attempt versus multiple attempt status. Of the first-attempt characteristics examined, only age of first attempt, OR = 0.33, 95% CI [0.17–0.63], p = .001, and receipt of treatment following attempt, OR = 0.28, 95% CI [0.09–0.88], p = .028, significantly distinguished SA vs. MA status, even after controlling for current age and depression at the time of first attempt. Female and White participants were overrepresented in this sample, which limits generalization to more heterogenous and diverse samples. The cross-sectional nature of data introduces the potential for retrospective recall bias. Younger age of first attempt and lack of receipt of mental health treatment following a first attempt were associated with multiple attempt status. These findings highlight the importance of early mental health screening, parental psychoeducation, and linkage to mental health care after a suicide attempt.

Predictors of future suicide attempt among adolescents with suicidal thoughts or non-suicidal self-harm: a population-based birth cohort study

SummaryBackgroundSuicidal thoughts and non-suicidal self-harm are common in adolescents and are strongly associated with suicide attempts. We aimed to identify predictors of future suicide attempts in these high-risk groups.MethodsParticipants were from the Avon Longitudinal Study of Parents and Children, a population-based birth cohort study in the UK. The sample included 456 adolescents who reported suicidal thoughts and 569 who reported non-suicidal self-harm at 16 years of age. Logistic regression analyses were used to explore associations between a wide range of prospectively recorded risk factors and future suicide attempts, assessed at the age of 21 years.Findings38 (12%) of 310 participants with suicidal thoughts and 46 (12%) of 380 participants who had engaged in non-suicidal self-harm reported having attempted suicide for the first time by the follow-up at 21 years of age. Among participants with suicidal thoughts, the strongest predictors of transition to attempts were non-suicidal self-harm (odds ratio [OR] 2·78, 95% CI 1·35–5·74; p=0·0059), cannabis use (2·61, 1·11–6·14; p=0·029), other illicit drug use (2·47, 1·02–5·96; p=0·045), exposure to self-harm (family 2·03, 0·93–4·44, p=0·076; friend 1·85, 0·93–3·69, p=0·081), and higher levels of the personality type intellect/openness (1·62, 1·06–2·46; p=0·025). Among participants with non-suicidal self-harm at baseline, the strongest predictors were cannabis use (OR 2·14, 95% CI 1·04–4·41; p=0·038), other illicit drug use (2·17, 1·10–4·27; p=0·025), sleep problems (waking in the night 1·91, 0·95–3·84, p=0·069; insufficient sleep 1·97, 1·02–3·81, p=0·043), and lower levels of the personality type extraversion (0·71, 0·49–1·03; p=0·068).InterpretationMost adolescents who think about suicide or engage in non-suicidal self-harm will not make an attempt on their life. Many commonly cited risk factors were not associated with transition to suicide attempt among these high-risk groups. Our findings suggest that asking about substance use, non-suicidal self-harm, sleep, personality traits, and exposure to self-harm could inform risk assessments, and might help clinicians to identify which adolescents are at greatest risk of attempting suicide in the future.FundingAmerican Foundation for Suicide Prevention, National Institute for Health Research Biomedical Research Centre at the University Hospitals Bristol National Health Service Foundation Trust, and the University of Bristol.

Prevalence of suicidal behaviour and associated factors in a large sample of Chinese adolescents.

Suicidal behaviour is prevalent among adolescents and is a significant predictor of future suicide attempts (SAs) and suicide death. Data on the prevalence and epidemiological characteristics of suicidal behaviour in Chinese adolescents are limited. This study was aimed to examine the prevalence, characteristics and risk factors of suicidal behaviour, including suicidal thought (ST), suicide plan (SP) and SA, in a large sample of Chinese adolescents. This report represents the first wave data of an ongoing longitudinal study, Shandong Adolescent Behavior and Health Cohort. Participants included 11 831 adolescent students from three counties of Shandong, China. The mean age of participants was 15.0 (s.d. = 1.5) and 51% were boys. In November-December 2015, participants completed a structured adolescent health questionnaire, including ST, SP and SA, characteristics of most recent SA, demographics, substance use, hopelessness, impulsivity and internalising and externalising behavioural problems. The lifetime and last-year prevalence rates were 17.6 and 10.7% for ST in males, 23.5 and 14.7% for ST in females, 8.9 and 2.9% for SP in males, 10.7 and 3.8% for SP in females, 3.4 and 1.3% for SA in males, and 4.6 and 1.8% for SA in females, respectively. The mean age of first SA was 12-13 years. Stabbing/cutting was the most common method to attempt suicide. Approximately 24% of male attempters and 16% of female attempters were medically treated. More than 70% of attempters had no preparatory action. Female gender, smoking, drinking, internalising and externalising problems, hopelessness, suicidal history of friends and acquaintances, poor family economic status and poor parental relationship were all significantly associated with increased risk of suicidal behaviour. Suicidal behaviour in Chinese adolescents is prevalent but less than that previously reported in Western peers. While females are more likely to attempt suicide, males are more likely to use lethal methods. Multiple child and family factors are associated with suicidal behaviour. These findings highlight the importance of early screening and intervention of suicidal behaviour in Chinese adolescents.

Using CBT over 3 months to prevent suicide attempts in high‐risk youth

Suicide attempts are increasing among youth. Even more common are nonfatal suicide attempts, defined as self‐directed behaviors resulting in injury or potential for injury in which suicide could result, as well as broader self‐harm and nonsuicidal self‐injury (NSSI). Because NSSI is a powerful predictor of future suicide attempts, it is important to have a way to prevent such attempts in these high‐risk youths. However, there are no proven interventions for preventing suicide attempts by youths who are harming themselves, a gap researchers addressed by evaluating Safe Alternatives for Teens and Youths (SAFETY).

Investigaciones sobre ideación suicida en Colombia, 2010-2016

Introducción: la ideación suicida ha sido considerada como la primera etapa del espectro suicida y, por consiguiente, el principal predictor de futuros intentos de suicidio e incluso de suicidio consumado, siendo mayor el riesgo de suicidio en el primer año de la presencia de ideación suicida. Los datos reportados, tanto a nivel mundial, como nacional, reflejan una tendencia al aumento en la prevalencia de conductas suicidas, convirtiéndose, por tanto, en un problema de salud pública.Objetivo: conocer los hallazgos relacionados con la ideación suicida en población colombiana a partir del análisis de los artículos publicados durante el periodo comprendido entre el 2010 y el 2016, recuperados a través de los sistemas de información Redalyc, ScienceDirect, Medline, Mediclatina y Scopus.Método: la búsqueda se realizó a partir de los resúmenes encontrados, vinculando las áreas de conocimiento de psicología, medicina y ciencias sociales.Resultados: fueron hallados en total 22 artículos en los que se estudió la ideación suicida de manera independiente o relacionándola con otras variables, predominando las investigaciones de carácter cuantitativo de tipo descriptivo o correlacional, abordadas, principalmente, desde el campo de la psicología clínica, y cuyo grupo poblacional estuvo enmarcado en adolescentes y adultos jóvenes.Conclusión: se identificó un marcado interés académico e investigativo en el diagnóstico clínico del componente cognitivo del suicidio, siendo evidente el déficit en investigaciones relacionadas con la prevención o intervención de este factor de riesgo, a pesar de considerarse como un problema de salud pública.

Longitudinal Prediction of Suicide Attempts for a Diverse Adolescent Sample of Native Hawaiians, Pacific Peoples, and Asian Americans

The objective of this study was to determine the longitudinal predictors of past-6-month suicide attempts for a diverse adolescent sample of Native Hawaiians, Pacific peoples, and Asian Americans. The study used longitudinal data from the Hawaiian High Schools Health Survey (N = 2,083, 9th to 11th graders, 1992–1993 and 1993–1994 school years). A stepwise multiple logistic regression was conducted. The final model consisted of three statistically significant predictors: (1) Time 1 suicide attempt, odds ratio = 30.6; (2) state anxiety, odds ratio = 4.9; and (3) parent expectations, odds ratio = 1.9. Past suicide attempt was by far the strongest predictor of future suicide attempts. Implications are discussed, including the need for screening of prior suicide attempts and focused interventions after suicide attempts.

Predictors of Future Suicide Attempts Among Individuals Referred to Psychiatric Services in the Emergency Department: A Longitudinal Study.

This study examined which factors predict future suicide attempts (SAs) among people referred to psychiatric services in the emergency department (ED). It included consecutive adult (age >18 years) presentations (N = 6919) over a 3-year period to the two tertiary care hospitals in Manitoba, Canada. Medical professionals assessed each individual on 19 candidate risk factors. Stepwise logistic regression and receiver operating characteristic curves examined the association between the baseline variables and future SAs within the next 6 months. A total of 104 individuals re-presented to the ED with future SAs. Of the 19 baseline variables, only two independently accounted for the variance in future attempts. High-risk scores using this two-item model were associated with elevated odds of future SA (odds ratio, 3.22; 95% confidence interval, 1.62-6.42; p < 0.01), but this was tempered by a low positive predictive value. Further evaluation is required to determine if this two-item tool could help identify people requiring more comprehensive risk assessment referred to psychiatry in the ED.

Are predictors of future suicide attempts and the transition from suicidal ideation to suicide attempts shared or distinct: A 12-month prospective study among patients with depressive disorders

Our study aimed to examine the interplay between clinical and social predictors of future suicide attempt and the transition from suicidal ideation to suicide attempt in depressive disorders. Sixty-six Malaysian inpatients with a depressive disorder were assessed at index admission and within 1 year for suicide attempt, suicidal ideation, depression severity, life event changes, treatment history and relevant clinical and socio-demographic factors. One-fifth of suicidal ideators transitioned to a future suicide attempt. All future attempters (12/66) had prior ideation and 83% of attempters had a prior attempt. The highest risk for transitioning from ideation to attempt was 5 months post-discharge. Single predictor models showed that previous psychiatric hospitalization and ideation severity were shared predictors of future attempt and ideation to attempt transition. Substance use disorders (especially alcohol) predicted future attempt and approached significance for the transition process. Low socio-economic status predicted the transition process while major personal injury/illness predicted future suicide attempt. Past suicide attempt, subjective depression severity and medication compliance predicted only future suicide attempt. The absence of prior suicide attempt did not eliminate the risk of future attempt. Given the limited sample, future larger studies on mechanisms underlying the interactions of such predictors are needed.

Nonsuicidal self-injury as a prospective predictor of suicide attempts in a clinical sample of military personnel

BackgroundNonsuicidal self-injury (NSSI) is a risk factor for suicide attempts, but it has received little attention in military populations, for whom suicide rates have doubled over the past decade. In the current study, the relationship of NSSI with future suicide attempts was prospectively examined in a sample of active duty Soldiers receiving outpatient psychiatric treatment for suicide ideation and/or a recent suicide attempt. MethodsData were collected as part of a two-year prospective study of 152 active duty Soldiers (87% male, 71% Caucasian, mean age=27.53) in outpatient mental health care who reported current suicide ideation and/or a suicide attempt during the month preceding intake. Suicide attempts and NSSI were assessed using the Suicide Attempt Self Injury Interview. ResultsForty percent of Soldiers with a history of nonsuicidal self-injury and 25% of Soldiers with a history of suicide attempt made a suicide attempt during the 2-year follow-up. Soldiers with a history of nonsuicidal self-injury were more than twice as likely to make a subsequent suicide attempt (hazard ratio [HR]=2.25, P=.045). Soldiers with a history of suicide attempt were no more likely to make a subsequent suicide attempt than Soldiers without a previous suicide attempt (HR=.88, P=.787). Thirty percent of Soldiers with a history of suicide attempt had also engaged in nonsuicidal self-injury. Forty-two percent of Soldiers with histories of both nonsuicidal self-injury and suicide attempt made a subsequent suicide attempt and were more likely to make a suicide attempt during follow-up than Soldiers with a history of suicide attempt only. Number of NSSI episodes, but not number of suicide attempts, was significantly associated with increased risk for future suicide attempt. Results were unchanged when adjusting for baseline symptom severity. LimitationsPredominantly male, active duty Army sample. ConclusionsAmong Soldiers in outpatient mental health care, a history of NSSI is a stronger predictor of future suicide attempts than a history of suicide attempts. Soldiers with a history of both NSSI and suicide attempt are at especially increased risk.

Association of solitary binge drinking and suicidal behavior among emerging adult college students.

Emerging adult college students who binge drink in solitary contexts (i.e., while alone) experience greater depression and suicidal ideation than do students who only binge drink in social contexts, suggesting that they may be at greater risk for suicidal behavior. This study examined the association of a previous suicide attempt, one of the best predictors of future suicide attempts and suicide, and severity of recent suicidal ideation with drinking in solitary and social contexts. Participants were binge drinking, emerging adult (18- to 25-year-old) college students (N=182) drawn from two studies of college drinkers. A logistic regression analysis revealed that both suicide attempt history and severity of suicidal ideation were significantly associated with a greater likelihood of being a solitary binge drinker as opposed to only a social binge drinker. Students with a previous suicide attempt were nearly four times more likely to be solitary binge drinkers. Multiple regression analyses revealed that suicide attempt history was significantly associated with greater frequency and quantity of drinking in solitary, but not social contexts. Suicidal ideation was significantly associated with drinks per solitary drinking day, but not frequency of solitary drinking once suicide attempt history was accounted for. Given the associations found between solitary binge drinking and a history of suicide attempts, as well as greater severity of recent suicidal ideation, it appears that these students are in need of suicide prevention efforts, including treatment efforts aimed at reducing binge drinking.

Predicting future suicide attempts among depressed suicide ideators: A 10-year longitudinal study

Suicidal ideation and attempts are a major public health problem. Research has identified many risk factors for suicidality; however, most fail to identify which suicide ideators are at greatest risk of progressing to a suicide attempt. Thus, the present study identified predictors of future suicide attempts in a sample of psychiatric patients reporting suicidal ideation. The sample comprised 49 individuals who met full DSM-IV criteria for major depressive disorder and/or dysthymic disorder and reported suicidal ideation at baseline. Participants were followed for 10 years. Demographic, psychological, personality, and psychosocial risk factors were assessed using validated questionnaires and structured interviews. Phi coefficients and point-biserial correlations were used to identify prospective predictors of attempts, and logistic regressions were used to identify which variables predicted future attempts over and above past suicide attempts. Six significant predictors of future suicide attempts were identified – cluster A personality disorder, cluster B personality disorder, lifetime substance abuse, baseline anxiety disorder, poor maternal relationship, and poor social adjustment. Finally, exploratory logistic regressions were used to examine the unique contribution of each significant predictor controlling for the others. Comorbid cluster B personality disorder emerged as the only robust, unique predictor of future suicide attempts among depressed suicide ideators. Future research should continue to identify variables that predict transition from suicidal thoughts to suicide attempts, as such work will enhance clinical assessment of suicide risk as well as theoretical models of suicide.

Fait Accompli: Suicide in a Rural Trauma Setting

Over the past 20 years, the rate of suicide in rural communities has surpassed those of urban areas. The number of rural trauma patients who attempt suicide, are treated and survive at a trauma center, but ultimately reattempt suicide and succeed (suicide recidivists) is unknown. We have characterized all adult suicide deaths seen at a rural Level I trauma center and identified predictors of a successful suicide. We hypothesized that rural adult trauma patients exhibit a high rate of suicide recidivism. This is a 10-year single institutional retrospective cohort analysis. All adult admissions to our rural, Level I trauma center from 1997 to 2007 (n = 9147) were cross referenced with a Vermont Medical Examiner database containing information regarding all suicide deaths in the state of Vermont from 2002 to 2007 (n = 502); the 32 matches are the subject of this research. One half (16 of 32) of patients who died by suicide had a previous admission to the trauma service. Index hospital length of stay (LOS, p < 0.02), intensive care unit-LOS (p < 0.01), and ventilator days (p < 0.01) were significantly different between trauma patients who subsequently died by suicide and general trauma patients. The average delay from initial presentation to suicide death was 2.8 years. Eighteen of 28 (64%) of suicide attempters had previous trauma admissions for self-inflicted injury (p < 0.001). Eighteen of 156 (12%) of previous self-inflicted injury admissions resulted in future suicide attempt (NNT = 9). A logistic regression model identified the following variables present at the index hospitalization as significant predictors of future suicide: self-inflicted injury, penetrating mechanism of injury, longer hospital LOS, younger age, and female gender. The overwhelming majority (94%) of suicide deaths in our rural state were never seen by the trauma center, and only 1.1% were recidivists. Previous admissions for self-inflicted injuries or penetrating injuries were significant predictors of future suicide attempt and should trigger select interventions. Other factors that can to lead a suicidal tendency include a previous mental health history (depression), poly-substance abuse, and chronic pain history. In our small sample, suicidal tendencies could persist for a prolonged period of time.

Predictive and concurrent validity of the Suicidal Ideation Questionnaire among American Indian adolescents.

Suicide is currently the second leading cause of death for ages 15-24 years; reports indicate that 6-8% of American teens have attempted suicide. Rates of suicide and suicide attempts are at least as high, if not higher, for American Indian adolescents and young adults. The Suicidal Ideation Questionnaire (Junior High School Version) (SIQ-JR) could be used to identify young people who may be at risk for attempting suicide, since this questionnaire focuses on suicidal ideation, a major risk factor for suicide attempt. However, little is known about the predictive validity of the SIQ-JR, particularly in American Indian adolescent populations. A suicide attempt cluster at an American Indian boarding school provided the unique opportunity to examine the performance of the SIQ-JR in a group of American Indian high school students who had taken the SIQ-JR approximately 2 months prior to the outbreak of attempts. The SIQ-JR proved to be an excellent predictor of future suicide attempts when compared to other measures of distress: anxiety, depression, and alcohol use. The SIQ-JR is an effective screener for suicide risk in this American Indian adolescent population.
