Do Undiagnosed Suicide Decedents Have Symptoms of a Mental Disorder?

A national survey of doctoral psychology education and training in suicide risk and violence risk assessment and management

INTRODUCTION

When, in the judgment of a mental health professional, patient suicide risk and/or patient violence risk are considered imminent, they have been referred to as behavioral emergencies. Past surveys have suggested that education and training with these emergency situations have been inadequate. The present study was undertaken to obtain more current information on the training that psychologists receive in these areas of practice.

METHOD

All directors of APA-accredited graduate psychology programs and all directors of APA-accredited predoctoral psychology internship programs were asked to complete an online survey inquiring about such training provided in their programs.

RESULTS

Results indicated that both sets of directors rated such doctoral training in suicide risk assessment and management as very important. Internship directors, however, were significantly more likely than graduate program directors to state that psychologists should be required to complete continuing education courses on other-directed violence risk. Serious gaps in training were identified; that is, only 59.2% of psychology graduate directors reported that their program offered training in safety planning for suicide risk and only 25.4% reported that their program offered training in safety planning for violence risk.

CONCLUSION

Given that serious injury and even death can occur from patient suicidal behavior and/or a patient violent behavior, the implications of these findings are discussed.

Health Service Protection vis-à-vis the Detection of Psychosocial Risks of Suicide during the Years 2019-2021

Health services are especially relevant in suicide prevention and intervention, representing a favourable environment in which to implement specific strategies to detect and address suicidal behaviours. Indeed, a significant proportion of people who die by suicide (DBS) present at primary care and mental health services during the last year, month, or even days before committing suicide. The objective of this descriptive and cross-sectional study of all registered cases of death by suicide (N = 265) in Extremadura (Spain) was to determine which of those people who died by suicide had mental health problems (MHP) and what type of assistance they had requested. Diagnoses, previous suicide attempts, type of health service, and last visit before death were explored with univariate analyses and logistic regressions. The proportion of people without MHP was found to be high, and these people had hardly visited the health services at all in their last year. People with MHP, between the ages of 40 and 69, and with previous suicide attempts were more likely to have visited the mental health service in the three months prior to their death. It is, thus, necessary to provide health professionals with tools and training in the prevention of and approach to suicide. Efforts must be directed towards effectively assessing mental health and the risk of suicide since a large proportion of people who die by suicide may go unnoticed.

Suicide, Firearms, and Terminal Illness: A Latent Class Analysis Using Data From the National Violent Death Reporting System

OBJECTIVE

Firearms are highly lethal when used for suicide and are used more frequently as a suicide method by persons of older age. Individuals with terminal illness are at high risk for suicide, yet little research has explored how firearms may be used for self-harm in this population. The authors sought to understand the patterns of psychiatric diagnoses, substance use disorders diagnoses, and suicide mechanisms for individuals with terminal illness who died by suicide as well as their demographic and circumstantial characteristics.

METHODS

A latent class analysis using data from the National Violent Death Reporting System was undertaken to better understand typologies of individuals with terminal illness who died by suicide in 2003-2018 (N=3,072). To develop the classes, the authors considered diagnoses of mental illness and of alcohol or substance use disorders, suicidal thoughts and behaviors, and mechanism of suicide (firearm or no firearm). Demographic and circumstantial variables were examined across classes.

RESULTS

The analysis revealed four classes of persons with terminal illness who died from suicide: depression and nonfirearm methods (N=375, 12%), suicidal intent and firearm use (N=922, 30%), alcohol or substance use disorder and nonfirearm methods (N=70, 2%), and firearm use only (N=1,705, 56%).

CONCLUSIONS

Firearm access is an important consideration for terminally ill persons at risk for suicide. Screening for psychiatric and substance use disorders may not identify terminally ill persons who are at increased suicide risk because of the presence of a firearm in the home. This population may benefit from tailored interventions in specialty care settings to address firearm safety.

Comparing warning signs of suicide between suicide decedents with depression and those non-diagnosed psychiatric disorders

OBJECTIVE

Early recognition of a high-risk group impending suicide is important. We aimed to compare warning signs depending on the nature of the psychiatric disorder and whether it was a documented diagnosis.

METHODS

Data of suicide decedents were collected from police records from 2013 to 2017. We evaluate psychiatric symptoms and warning signs in three aspects (language, behavior, and affect) using the Korea-Psychological Autopsy Checklist for Police Records (K-PAC-PR).

RESULTS

A total of 13,265 suicide decedents were recruited for this study. Of them, 66.9% of females and 46.7% of males diagnosed psychiatric disorders, with depressive disorder being the most common one. Warning signs were observed in 93.0% of suicide decedents. They were observed more in those who were diagnosed with psychiatric disorders, especially in those with a depressive disorder. "Talking about dying or suicide" was the most common warning sign in all groups, and "apathetic behavior" was the most related warning sign for depressive disorder. Especially for "talking about dying or suicide," the proportion of observed "within a week" was high, making it valuable as a warning sign.

CONCLUSION

Warning signs were commonly found in suicide decedents regardless of gender. They were more common among the decedents diagnosed with psychiatric disorders, especially among those with a depressive disorder.

Psychological autopsy study comparing suicide decedents with and without a history of suicide attempts in a nationwide sample of South Korea

The majority of suicide decedents die on their initial attempt. To bring attention to suicide decedents without a suicide attempt history, the current study explored their demographic, clinical, and suicide-related characteristics. The data were derived from the Korea National Investigation of Suicide Victims Study, which assessed all suicide cases from 2013 to 2017 recorded in police investigation reports. We compared suicide decedents with and without a history of nonfatal attempts using the Korea Psychological Autopsy Checklist for Police Records (K-PAC). Out of 5228 cases included in our study, 3147 (60.2%) died on their first suicide attempt. Demographically, those who were male, older than 65, employed, and married/widowed were more likely to die on their initial attempt. Clinically, those who died on their initial attempt were more likely to have never been diagnosed with psychiatric disorders, whereas those who died on a repeated attempt were more likely to have been diagnosed with mood disorders. In terms of suicide-related factors, experiencing relationship problems and complaining about physical discomfort were associated with dying on an initial attempt. Depressed affect, self-harming behaviors, and talking about suicide or death were associated with repeated attempts.

Subthreshold lifetime depression and anxiety are associated with increased lifetime suicide attempts: A Korean nationwide study

BACKGROUND

Subthreshold depression and anxiety are highly prevalent and known to be associated with functional limitations and future onset of major depression or anxiety disorders. However, studies regarding suicidality at subthreshold levels of depression and anxiety are limited.

METHODS

A total of 17,639 Koreans aged from 18 to 64 responded to the Korean version of the WHO-composite international diagnostic interview (K-CIDI) version 2.1 between 2006 and 2016. Prevalence of subthreshold depression and anxiety, and information on lifetime suicide attempt (SA) were assessed. Multivariable logistic regression was performed to calculate the risk of SA by the level of depression or anxiety.

RESULTS

The risk of lifetime SA increased incrementally according to the level of depression and anxiety. In the subthreshold depression group, individuals with subthreshold anxiety increased the odds about threefold (OR = 3.15, 95% CI 3.12-3.18) and the threshold anxiety disorder group increased the odds about fivefold (OR = 5.33, 95% CI 5.27-5.38) for SA, compared to the group without any level of anxiety. In threshold depressive disorder, the subthreshold anxiety group showed about 1.8-fold higher odds (OR = 1.76, 95% CI 1.75-1.77) and the threshold anxiety disorder group showed threefold higher odds (OR = 2.93, 95% CI 2.92-2.95) for SA compared to the group without any level of anxiety.

CONCLUSIONS

Subthreshold levels of depression and anxiety were prevalent among Koreans and were associated with an increased prevalence of lifetime SA. A detailed assessment of depression and anxiety symptoms according to their level should be performed on a diagnostic continuum to prevent suicide.

Mental Disorders, Gun Ownership, and Gun Carrying Among Soldiers After Leaving the Army, 2016-2019

Objectives. To examine associations of current mental and substance use disorders with self-reported gun ownership and carrying among recently separated US Army soldiers. Veterans have high rates of both gun ownership and mental disorders, the conjunction of which might contribute to the high suicide rate in this group. Methods. Cross-sectional survey data were collected in 2018-2019 from 5682 recently separated personnel who took part in the Army Study to Assess Risk and Resilience in Servicemembers. Validated measures assessed recent mood, anxiety, substance use, and externalizing disorders. Logistic regression models examined associations of sociodemographic characteristics, service characteristics, and mental disorders with gun ownership and carrying. Results. Of the participants, 50% reported gun ownership. About half of owners reported carrying some or most of the time. Mental disorders were not associated significantly with gun ownership. However, among gun owners, major depressive disorder, panic disorder, posttraumatic stress disorder, and intermittent explosive disorder were associated with significantly elevated odds of carrying at least some of the time. Conclusions. Mental disorders are not associated with gun ownership among recently separated Army personnel, but some mental disorders are associated with carrying among gun owners.

Association of mental disorders with firearm suicides: A systematic review with meta-analyses of observational studies in the United States

In the United States (US), 61% of all suicide cases may involve firearms, and some evidence suggests that mental disorders may play a role in suicide by firearm. We performed the first systematic review and meta-analyses to investigate: (i) whether mental disorders are associated with suicide by firearm, and (ii) whether the risk of using a firearm compared with alternative means is associated with higher levels of suicide in individuals with a mental disorder METHODS AND FINDINGS: We searched twelve databases from inception to the 24th of May 2020. We retrieved 22 observational studies conducted in the US. Random-effects meta-analyses showed individuals who had a diagnosis of a mental disorder had lower odds (odds ratios (OR)= 0.50, 95% CI: 0.36 to 0.69; I²=100 (95% CI: 87 to 100%), of dying by suicide with a firearm than those who did not have a diagnosis of a mental disorder. Secondary analysis showed that decedents who had a mental health diagnosis resulted in lower odds of dying by suicide by using firearms than using other means LIMITATIONS: Risk of bias revealed a heterogeneous and poor definition of mental disorders as well as lack of control for potential demographic confounding factors. In the meta-analyses, studies were combined in the same analytic sample as 77% of these studies did not specify the type of mental disorder CONCLUSION: While our results seem to suggest that having a mental disorder may not be consistently associated with the odds of dying by suicide using a firearm, the presence of substantial heterogeneity and high risk of bias precludes any firm conclusions.

Anxiety, Depression, and the Interpersonal Theory of Suicide in a Community Sample of Adults with Autism Spectrum Disorder

The present study examines occurrence of depression, anxiety, and suicidality in adults with autism spectrum disorder (ASD), relationships between social difficulties and mental health, and application of the Interpersonal Theory of Suicide in this population. Ninety-eight adults with ASD completed an online survey. Data were analyzed using bivariate correlations, independent samples t-tests, and simple mediational analyses. A substantial proportion reported a lifetime history of anxiety (63%), depression (55%), and suicide attempts (19%), as well as recent suicidal ideation (12%). Social difficulty was associated with higher psychiatric concerns. Thwarted belongingness and perceived burdensomeness were associated with social dissatisfaction, current suicidal ideation, and history of depression. Results suggest the need for widespread screening and intervention services for co-occurring psychiatric conditions in this population.

Borderline personality disorder and self-directed violence in a sample of suicidal army soldiers

There has been a sharp increase in the military suicide rates in 2004. While, borderline personality disorder (BPD) has a stronger association with suicide attempts than any other mental health disorder, there is limited evidence concerning the prevalence and scope of BPD symptoms among military personnel. This secondary data analysis compared active duty suicidal soldiers to characterize the presence-absence of BPD diagnostic criteria and lifetime history of self-directed violence in a suicidal military sample. The current study examined data of 137 active Service Members with significant suicidal ideation. Approximately one-quarter of the soldiers in this sample met full diagnostic criteria for BPD. The presence of BPD criteria was generally consistent among participants with BPD who reported past self-directed violence relative to those who did not. The number of BPD criteria was a significant predictor of the odds of reporting any nonsuicidal self-injury (NSSI) as well as the amount of NSSI, but was not associated with suicide attempt. This study demonstrated that a nontrivial proportion of suicidal soldiers meet criteria for this condition, which is strongly associated with self-directed violence. It is important to rigorously assess for the presence-absence of BPD criteria among suicidal military personnel and cultivate prevention strategies and treatment options for BPD.

The Interpersonal and Psychological Impacts of COVID-19 on Risk for Late-Life Suicide

Older adults experience increased risk for suicide compared to the general population, and the circumstances surrounding the Coronavirus Disease 2019 (COVID-19) may potentiate this risk. We discuss how current COVID-19 pandemic-related policies are likely to harm older adults disproportionately. COVID-19 pandemic social distancing policies and ethical guidelines for COVID-19 treatment may exacerbate experiences of social isolation, perceived expendability, and exposure to suffering, which are related to the three main components of the Interpersonal Theory of Suicide (i.e., thwarted belongingness, perceived burdensomeness to society, and capability for suicide). The COVID-19 pandemic poses a drain on services and has drawn ethical debates about policies around treating younger adults first. These experiences may lead older adults to have reduced access to needed medical and psychiatric services and may convey damaging messages of expendability. Further, the potential prolonged stress associated with the COVID-19 pandemic may impact neurological, immunological, and health functioning – exacerbating suicide risk. Potential venues to increase treatment options and decrease social isolation are discussed. We acknowledge optimistic effects as well, such as ‘pulling together’ as a society and the many valuable ways older adults may contribute during this crisis.

Maternal deaths by suicide in Queensland, Australia, 2004-2017: an analysis of maternal demographic, psychosocial and clinical characteristics

To characterise the demographic and clinical characteristics of women who died by suicide in the perinatal period to inform and improve suicide prevention strategies. Retrospective analysis of maternal suicides during and within 1 year after the end of pregnancy in Queensland between January 2004 and December 2017. Outcomes measured included timing of death in relation to pregnancy, sociodemographic and clinical characteristics and health service use prior to death. There were 65 deaths by suicide in the study period; six occurred during pregnancy, 30 occurred after a live birth, 22 occurred after a termination of pregnancy and seven followed a miscarriage or stillbirth. Most suicides were late maternal deaths. Women were younger, and more likely to identify as Aboriginal or Torres Strait Islander, when compared to all women giving birth for the same time period. Most women had a prior mental health diagnosis, most commonly depression. Over half of women had recent relationship separation or conflict prior to death. Perinatal women had higher rates of death by violent means than all women in Queensland who died by suicide during the same time period. The demographic, psychosocial and clinical characteristics of a group of women who died by suicide have been described, and this shows a high proportion of women with a prior mental health diagnosis. To reduce maternal mortality, psychosocial screening must be implemented broadly and continued until the end of the first year postpartum. Similar screening attention is needed for women who had a termination of pregnancy, miscarriage or stillbirth.

Characteristics of persons who die on their first suicide attempt: results from the National Violent Death Reporting System

BACKGROUND

Much of suicide research focuses on suicide attempt (SA) survivors. Given that more than half of the suicide decedent population dies on their first attempt, this means a significant proportion of the population that dies by suicide is overlooked in research. Little is known about persons who die by suicide on their first attempt-and characterizing this understudied population may improve efforts to identify more individuals at risk for suicide.

METHODS

Data were derived from the National Violent Death Reporting System, from 2005 to 2013. Suicide cases were included if they were 18-89 years old, with a known circumstance leading to their death based on law enforcement and/or medical examiner reports. Decedents with and without a history of SA were compared on demographic, clinical, and suicide characteristics, and circumstances that contributed to their suicide.

RESULTS

A total of 73 490 cases met criteria, and 57 920 (79%) died on their first SA. First attempt decedents were more likely to be male, married, African-American, and over 64. Demographic-adjusted models showed that first attempt decedents were more likely to use highly lethal methods, less likely to have a known mental health problem or to have disclosed their intent to others, and more likely to die in the context of physical health or criminal/legal problem.

CONCLUSIONS

First attempt suicide decedents are demographically different from decedents with a history of SA, are more likely to use lethal methods and are more likely to die in the context of specific stressful life circumstances.

Suicide Risk Assessment and Prevention: Challenges and Opportunities

Despite increased access to mental health care for the previously uninsured and expanding evidence-based treatments for mood, anxiety, psychotic, and substance use disorders, suicide is on the rise in the United States. Since 1999, the age-adjusted suicide rate in the United States has increased 33%, from 10.5 per 100,000 standard population to 14.0. As of yet, there are no clinically available biomarkers, laboratory tests, or imaging to assist in diagnosis or the identification of the suicidal individual. Suicide risk assessment remains a high-stakes component of the psychiatric evaluation and can lead to overly restrictive management in the name of prevention or to inadequate intervention because of poor appreciation of the severity of risk. This article focuses primarily on suicide risk assessment and management as a critical first step to prevention, given the fact that more research is needed to identify precision treatments and effective suicide prevention strategies. Suicide risk assessment provides the clinical psychiatrist with an opportunity for therapeutic engagement with the ultimate goals of relieving suffering and preventing suicide.

Suicide in DSM-5: Current Evidence for the Proposed Suicide Behavior Disorder and Other Possible Improvements

Suicide continues to be one of the greatest challenges faced by mental health clinicians and researchers, an issue made worse by increasing trends in the global suicide rate. Suicide behavior disorder (SBD) was introduced in DSM-5 as a disorder for further consideration and potential acceptance into the diagnostic system. There are numerous positive developments that would arise from the addition of a suicide-related diagnosis. Utilizing the 2009 guidelines established by Kendler and colleagues, the present review examines the evidence for SBD's validity and discusses the diagnosis' potential clinical benefits and limitations. Altogether, growing evidence indicates that SBD has preliminary validity and benefit. SBD presents with several significant limitations, however, and possible alternative additions to future DSMs are highlighted.

Is suicidality a mental disorder? Applying DSM-5 guidelines for new diagnoses

Suicidality-specific diagnoses have been proposed recently, but suicidologists are only just beginning to evaluate their merits. To advance this discussion, I introduce the term suicidal syndrome to describe the underlying entity, present a rationale for why a formal diagnosis is necessary, define the major features of the syndrome, and show how the syndrome could meet the requirements for new diagnostic candidates used in the development of the DSM-5. Against this backdrop, I examine common objections to a suicidality-specific diagnosis. Finally, I discuss several challenges with the creation of new diagnostic entities as they apply to suicidal syndrome.

Suicide ideation severity is associated with severe suicide attempts in a military setting

BACKGROUND

There is an ongoing debate on the effectiveness of suicidal behavior prevention measures in the military. The association of three widely used tools with severe suicide attempts was assessed in this setting.

METHODS

Thirty-nine Israeli soldiers (59% males), mean age 19 yrs., who attempted suicide during military service were divided into two groups: severe (n = 14; 35.9%) and moderate suicide attempts, and were assessed using the Scale for Suicide Ideation (SSI), Suicide Intent Scale (SIS) and the Columbia Suicide Severity Rating Scale (C-SSRS).

RESULTS

Seven items from the SSI (p = 0.008), two items from SIS and one item from C-SSRS were associated with severe suicide attempts. Kendall's tau-b correlation with bootstrap demonstrated stability of these correlations.

CONCLUSION

Greater severity of suicidal ideation was associated with more severe suicide attempts. The combination of male gender, available firearms and current severe suicide ideation is high-risk danger sign in a military setting, even when reported intent to die is low.

Relationship of Suicidal Ideation With Demoralization, Depression, and Anxiety: A Study of Cancer Patients in Mainland China

Demoralization is a form of psychological distress that may cause suicidal ideation. Demoralization syndrome is common among cancer patients, but there has been little empirical study on the association of suicidal ideation with demoralization, depression, and anxiety in this population. This study aims to investigate the prevalence of high demoralization among cancer patients in mainland China and the contribution of high demoralization to suicidal ideation beyond the impact of self-report depression and anxiety. In this cross-sectional study, 303 patients with cancer were invited to complete questionnaires. In total, 14.5% participants reported suicidal ideation and 49.50% high demoralization. Logistic regression analysis identified high demoralization as an independent risk factor for suicidal ideation. Only depression (odds ratio [OR], 6.68) had a stronger influence on suicidal ideation than demoralization (OR, 5.85), and patients with both depression and high demoralization were most likely to experience suicidal ideation. These findings suggest that measures of demoralization can help identify cancer patients at high suicide risk and that such patients require further attention and measures targeting demoralization for suicide prevention.

Suicidal behavior among substance users: data from the Second Brazilian National Alcohol and Drug Survey (II BNADS)

OBJECTIVE

To investigate the prevalence rates of suicidal ideation (SI) and suicide attempts (SA) and their association with substance use in a nationally representative sample of Brazilians.

METHODS

The Second Brazilian National Alcohol and Drug Survey (II BNADS) is a household cross-sectional survey that investigated the consumption of psychotropic drugs and associated risk factors. This national probability sample survey used a multistage cluster design to select 4,607 participants aged 14 or older and had a total response rate of 77%. Illegal drug use, SI and SA were obtained by confidential self-report assessment.

RESULTS

SI and SA were reported by 9.9 and 5.4% of the sample, respectively. This prevalence was 20.8 and 12.4% among individuals with alcohol use disorders (AUD), 31.5 and 16.5% among cannabis users and 40.0 and 20.8% among cocaine users. After adjusting for demographic characteristics, tobacco use, family history of suicide and depression, both SI and SA were positively associated with AUD, cannabis and cocaine use.

CONCLUSION

AUD, cannabis and cocaine use were significantly associated with SI and SA, even after the adjustments. Public health initiatives targeting suicide prevention should consider including assessment and management of substance misuse, and therapeutic approaches to substance misuse should include assessment of suicidality.

Depression and impulsiveness among soldiers who died by suicide: A psychological autopsy study

INTRODUCTION

Despite the accumulated knowledge about suicide, suicidal acts remain difficult to predict, and many suicides are acted out impulsively.

METHODS

We performed a psychological autopsy study based on inquiries about the deaths of all male soldiers aged 18-21 years who served in the Israeli army and died by suicide between 2009 and 2013 (n = 69). The study population was first divided into two groups: those who had depressive disorder (n = 31); and those who did not (n = 38). Socio-demographic characteristics of the subjects and the characteristics of the suicidal act were compared. Afterwards, the study population was re-divided by the presence or absence of impulsive personality traits (n = 22, and n = 47, respectively), and investigated for distinct suicidal behavior features.

RESULTS

No significant socio-demographic differences were found between the depressed and non-depressed suicide victims. The depressed group had showed more signs of planning the act (47% vs. 23%), and had expressed suicidal ideation in the days preceding the suicide (51.6% vs. 21%). One third of the subjects were found to have an impulsive personality trait, with significantly more histories of disciplinary issues, violence and cluster B personality disorders. Alcohol use during the act was significantly more prevalent among impulsive than non-impulsive subjects (45.4% vs. 14.9%).

CONCLUSION

Identification of distinct clinical groups of suicide victims among young males might help clinicians evaluate high risk cases, and may provide valuable opportunities to alleviate and prevent these events in the future.

Exposure to suicide and suicide bereavement among women firefighters: Associated suicidality and psychiatric symptoms

OBJECTIVE

To examine experiences with suicide exposure and bereavement among women firefighters.

METHODS

Women firefighters (N = 266, M_age  = 37.64y) completed self-report measures assessing their experiences with suicide exposure, history of suicidality, current psychiatric symptoms, and suicide risk.

RESULTS

Three-fourths (74.4%) of participants reported knowing someone who had died by suicide; of these participants, 31.3% reported losing a fellow firefighter to suicide. Exposure to suicide during one's firefighting career was associated with more severe psychiatric symptoms and suicide risk. Greater impact of a suicide death was significantly associated with more severe current suicide risk, even after controlling for prior suicidality and other psychiatric symptoms.

CONCLUSIONS

Women firefighters exposed to suicide during their careers may experience more severe psychiatric symptoms and increased suicide risk as compared to their counterparts without this exposure. In particular, women firefighters who are more severely impacted by a suicide loss may be at increased suicide risk.
