Completed versus attempted suicide in psychiatric patients: a psychological autopsy study

Personality Disorders and Suicide. A Systematic Review of Psychological Autopsy Studies

PURPOSE OF REVIEW

This systematic review explores the relationship between personality disorders (PDs) and lethal suicide behavior. Following PRISMA guidelines, the study examines psychological autopsy studies with suicide deaths and identified PDs. Inclusion criteria encompass studies using the psychological autopsy method, reporting PD diagnosis and suicide deaths, in English language and with no temporal restrictions. The search strategy, conducted in PubMed and Embase until December 2nd, 2023, utilized specific terms related to suicide, PD, and psychological autopsy. Quality assessment using the Newcastle Ottawa-Scale for case-control studies was employed.

RECENT FINDINGS

56 psychological autopsy studies were included in the systematic review, revealing a prevalence of PDs among suicide deaths, and emphasizing their role as significant suicide risk factors. The review underscores the impact of comorbid PDs and Axis I disorders on suicide risk, particularly if additional stressors are present. Gender differences in PD prevalence are noted, with impulsivity and alcohol abuse identified as universal risk factors. Despite extensive global data collection, limitations include potential methodological variations and biases inherent in psychological autopsy studies. This study, registered in PROSPERO (CRD42022322359), contributes essential insights into the prevalence, characteristics, and risk factors of PDs among suicide deaths.

Decoding Suicide Decedent Profiles and Signs of Suicidal Intent Using Latent Class Analysis

Importance

Suicide rates in the US increased by 35.6% from 2001 to 2021. Given that most individuals die on their first attempt, earlier detection and intervention are crucial. Understanding modifiable risk factors is key to effective prevention strategies.

Objective

To identify distinct suicide profiles or classes, associated signs of suicidal intent, and patterns of modifiable risks for targeted prevention efforts.

Design, Setting, and Participants

This cross-sectional study used data from the 2003-2020 National Violent Death Reporting System Restricted Access Database for 306 800 suicide decedents. Statistical analysis was performed from July 2022 to June 2023.

Exposures

Suicide decedent profiles were determined using latent class analyses of available data on suicide circumstances, toxicology, and methods.

Main Outcomes and Measures

Disclosure of recent intent, suicide note presence, and known psychotropic usage.

Results

Among 306 800 suicide decedents (mean [SD] age, 46.3 [18.4] years; 239 627 males [78.1%] and 67 108 females [21.9%]), 5 profiles or classes were identified. The largest class, class 4 (97 175 [31.7%]), predominantly faced physical health challenges, followed by polysubstance problems in class 5 (58 803 [19.2%]), and crisis, alcohol-related, and intimate partner problems in class 3 (55 367 [18.0%]), mental health problems (class 2, 53 928 [17.6%]), and comorbid mental health and substance use disorders (class 1, 41 527 [13.5%]). Class 4 had the lowest rates of disclosing suicidal intent (13 952 [14.4%]) and leaving a suicide note (24 351 [25.1%]). Adjusting for covariates, compared with class 1, class 4 had the highest odds of not disclosing suicide intent (odds ratio [OR], 2.58; 95% CI, 2.51-2.66) and not leaving a suicide note (OR, 1.45; 95% CI, 1.41-1.49). Class 4 also had the lowest rates of all known psychiatric illnesses and psychotropic medications among all suicide profiles. Class 4 had more older adults (23 794 were aged 55-70 years [24.5%]; 20 100 aged ≥71 years [20.7%]), veterans (22 220 [22.9%]), widows (8633 [8.9%]), individuals with less than high school education (15 690 [16.1%]), and rural residents (23 966 [24.7%]).

Conclusions and Relevance

This study identified 5 distinct suicide profiles, highlighting a need for tailored prevention strategies. Improving the detection and treatment of coexisting mental health conditions, substance and alcohol use disorders, and physical illnesses is paramount. The implementation of means restriction strategies plays a vital role in reducing suicide risks across most of the profiles, reinforcing the need for a multifaceted approach to suicide prevention.

Suicidal hanging in Pakistan: an exploratory two-year content analysis study

Suicidal hanging is common in Pakistan and is considered a serious challenge globally. We conducted a content analysis of reports about suicidal hangings published in six English-language newspapers in Pakistan between 1 January 2021 and 31 December 2022, employing a web-searching technique.124 news reports were yielded; suicidal authors were males (68.5%), Muslims (69.4%), and unmarried (31.4%), aged 16- 30 years old. Ligatures employed in hanging suicides were ropes (28.2%), fabrics (20.9%), and electric wires (20.1%). The most frequent leverage-points selected in suicides were ceiling fans (37%) followed by trees (11.2%). Familial discords (19.2%) and poverty (9.6%) were the leading risk factors for hanging suicide. Most of the suicides (58%) occurred equally in the spring (29%) and autumn (29%) months. These evidences suggest that psychological interventions on families are crucial. Also, dealing with poverty and other social consequences in Pakistan as in the rest of the world may probably reduce the rate of yearly suicides.

Epidemiological characteristics and hospitalization trajectories prior to suicide in Galicia between 2013 and 2016

INTRODUCTION

Addressing suicide requires an understanding of regional patterns of epidemiology, with health variables being central. However, the clinical profile of people who commit suicide has received little attention. The objectives of this study were to analyze the sociodemographic, clinical, and forensic characteristics of persons who committed suicide in Galicia between 2013 and 2016, analyze suicide mortality rates, and identify trajectories of hospitalizations and associated variables.

MATERIAL AND METHODS

A population study was carried out on the 1354 people who died by suicide in Galicia.

RESULTS

The most common profile was a retired man, 57.9 years old (SD=18.5), from an urban and inner area. 43.6% had been previously hospitalized, 41.6% had been diagnosed with physical disorders, and 26.8% with mental disorders. 48.2% had been prescribed psychiatric medications and 29.6% had received outpatient psychiatric care. The highest prevalence of death by suicide (27.5%) was in 2014, with the predominant method being hanging (59.1%). The average raw rate was 12.3/100,000. Three trajectories of hospitalizations emerged: 94.83% had experienced few hospitalizations; 2.95% an increasing pattern; and 2.22% a decreasing pattern. These trajectories were associated with number of psychiatric appointments, prescription of psychiatric medications, and diagnoses of physical and mental disorders.

CONCLUSIONS

These findings are crucial for detection and prevention.

The UT health Psychological Autopsy Interview Schedule (UTH- PAIS) - Description and reliability of diagnoses and transdiagnostic personality measures

Few studies have used psychological autopsies to evaluate large and diverse populations on transdiagnostically relevant variables such as personality, temperament, and trauma exposure; rather, they tend to focus on specific psychiatric disorders or manner of death. We therefore developed the UT Health Psychological Autopsy Interview Schedule (UTH-PAIS). The measure is described, and our results show that the PAIS diagnoses and dimensions can be reliably assessed. Furthermore, we were able to show that our sample of donated brains overall matches the demographic characteristics of a larger pool of individuals receiving a medical autopsy. In the Discussion we review the strengths and potential limitations of the study and outline in which context the PAIS will prove to be useful.

Risk Factors Associated With Various Severities of Suicidal and Non-Suicidal Self-Harm Among Israel Defense Forces Soldiers-A Nested Case-Control Study

OBJECTIVE

Severe suicide attempt is a major risk factor for completed suicide. The aim of the present study was to focus on suicide behavior and timing to gain better understanding of these populations.

METHOD

The nested case-control retrospective study based on medical records of 246,866 soldiers, who demonstrated suicide attempts of varying severity, including death by suicide were compared with soldiers who did not demonstrate such behavior.

RESULTS

Risk for death by suicide was associated with males, military seniority of less than 12 months. High frequency of visits with mental health care professionals was associated with being severe suicide attempters (SAs). Moderate suicide attempts were associated with being a male, visiting a primary care physician frequently, and belonging to one of the two latest immigrant groups in Israel (Ethiopians and former Soviet Union). Mild suicide attempts were associated with having a psychiatric diagnosis on the enlistment day, visiting a mental health care professional at high or average frequency, visiting a primary care physician at high or average frequency, being a male, and being born in the former Soviet Union. While the proportion of males demonstrating suicidal behavior was higher than the females', severe SAs were higher among females. There was a clear tendency of female suicide attempters at all levels to act toward the end of their military service.

CONCLUSIONS

Although half of the SAs were females, their characteristics may be similar to those of the male SAs, contrary to the sex differences in suicide behavior among civilians.

The impact of Covid-19 on unemployment across Italy: Consequences for those affected by psychiatric conditions

BACKGROUND

Severe psychological and psychosocial consequences of the COVID-19 pandemic are expected, especially for people already vulnerable to biological or psychosocial stressors, including those with mental health problems. The study aimed to investigate factors associated with the loss of jobs and unemployment during the COVID-19 pandemic. In particular, we investigated whether mental illness was associated with a higher risk of losing one's job because of the COVID-19 pandemic.

METHODS

Nineteen thousand four hundred ninety-six adults living in Italy were administered an online protocol including a sociodemographic checklist and questionnaires investigating suicide ideation and risk, mental health status and general distress (stress, anxiety, and depression), resilience, and perceived support.

RESULTS

One thousand two hundred seventy-four reported having lost their job because of the COVID-19 pandemic, and 5.4% of the sample reported a mental illness (mostly a depressive disorder). Unemployment was independently associated with mental illness, poor mental health, and depression. Mental illness was associated with the risk of losing one's job because of the COVID-19 pandemic, but not at the multivariate analyses. Those who lost their job because of the COVID-19 pandemic (compared to others) reported worse mental health and depression.

LIMITATIONS

The presence of mental illness was self-reported by respondents and the administered measures were self-reported questionnaires affected by social desirability and other response bias.

CONCLUSIONS

The COVID-19 pandemic and social isolation measures and lockdown used to contain its spread among the Italian population were associated with occupational insecurity, especially among the more vulnerable social categories.

Suicide in late life: A viewpoint

Suicide in old age represents a sad public health concern. Despite the global decline in rates of suicide and the general amelioration of quality of life and access to health care for older adults, their rates of suicide remain the highest virtually in every part of the world. With the aging of the world population and the growing number of mononuclear families, the risk of an increase in isolation, loneliness and dependency does not appear ungrounded. The Covid-19 pandemic is claiming the life of many older persons and creating unprecedented conditions of distress, particularly for this segment of the population. This article briefly examines the main characteristics of suicidal behavior in late life, including observations deriving from the spread of the Sars-2 coronavirus and possible strategies for prevention.

Risk factors for attempting suicide during the COVID-19 lockdown: Identification of the high-risk groups

Objectives

In the wake of the coronavirus disease 2019 (COVID-19) pandemic, we have witnessed a rise in the instances of mental health problems and the suicide-related mortality rates. This study aims to identify the suicide-related risk factors and stressors to determine the groups at a greater risk of attempting suicide during the COVID-19 lockdown.

Methods

This retrospective study examined 29 cases of attempted suicide during the 3-month COVID-19 lockdown in KSA. The suicide risk factors were evaluated using specific instrument the modified (SAD PERSONS) scale. It is an acronym for sex, age, depression, previous attempt, excess alcohol, rational thinking loss, social status, organized plan, no social supports and stated future intent.

Results

The lockdown stressors that may have triggered suicidal behaviours were identified as follows: psychological distress, relationship problems, financial difficulties, and extreme fear of the COVID-19 infection. While all age groups carried the risk of attempting suicide during the lockdown, patients with psychiatric disorders and women accounted for 69% and 65.5% of the cohort, respectively. Factors like hopelessness and depression were highly related to suicide attempts, as well as the statement of future intent to repeat the attempt, at 72.4% and 65.5% respectively. Almost two-thirds of the attempts made were serious, and many women felt unsafe in their own homes during the lockdown.

Conclusion

Patients with pre-existing psychiatric disorders and women carry high risk of attempting suicide during the COVID-19 lockdown. This study offers insights on the greater outreach efforts that can be carried out for these patients by calling for the prioritization of mental health care, improvement of domestic violence services, and strengthening of suicide prevention strategies.

The Role of Past Suicidal Behavior on Current Suicidality: A Retrospective Study in the Israeli Military

Past suicide attempts are a significant risk factor for future suicidality. Therefore, the present military-based study examined the past suicidal behavior of soldiers who recently made a severe suicide attempt. Our sample consisted of 65 active-duty soldiers (61.5% males), between the ages of 18 and 28 years old (M = 20.4, SD ± 1.3). The inclusion criterion was a recent severe suicide attempt, requiring at least a 24 h hospitalization. This sample was divided into two groups, according to previous suicidal behavior, namely whether their first suicide attempt was before or after enlistment (n = 25; 38.5% and n = 40; 61.5%, respectively). We then examined the lethality and intent of the recent event in regard to this division. Four measures were used to assess the subjects' suicidal characteristics: the Columbia Suicide Severity Rating Scale, the Self-Harm Behavior Questionnaire, the Suicidal Behaviors Questionnaire-Revised, and the Beck Scale for Suicide Ideation. No significant difference in the severity of the suicide attempts (either actual or potential severity) were found between those who had suicide attempts before enlistment and those who had their first attempt in the service. As a matter of fact, most of the suicide attempts that occurred for the first time during military service had used a violent method (58.3%, n = 21). Finally, using multivariate analyses, we found that current thoughts and behavior, rather than past suicidality, was the strongest predictor for the lethality of suicide attempts.

Life Stress and Suicide in Adolescents

Stress exposure is central to theories of suicide. To advance understanding of the relation between stress and suicide, we examined whether specific, theoretically-pertinent life stressors were differentially related to suicidal thinking versus suicidal behaviors among hospitalized adolescents. Participants were 197 (144 female) adolescents aged 13 to 19 years old (M = 15.61, SD = 1.48) recruited from an acute residential psychiatric treatment program. Participants were categorized into mutually exclusive groups: psychiatric controls (n = 38) with no lifetime history of suicide ideation or suicide attempts, suicide ideators (n = 99) with current ideation and no lifetime attempts, and suicide attempters (n = 60) with a lifetime history of suicide ideation and at least one attempt in the past month. Adolescents completed the Stress and Adversity Inventory for Adolescents (Adolescent STRAIN), which assessed life events and chronic difficulties occurring in five social-psychological categories: Interpersonal Loss, Physical Danger, Humiliation, Entrapment, and Role Change/Disruption. Additionally, they completed a structured interview and symptom questionnaires to capture concurrent psychopathology. Controlling for demographic and clinical covariates, only Interpersonal Loss events distinguished attempters from psychiatric controls (OR = 2.27) and ideators (OR = 1.49); no events or difficulties differentiated ideators from controls. These effects persisted when analyses were restricted to single attempters and when events following the most recent attempt were excluded. The findings elucidate potential social-environmental triggers of suicide. Ultimately, this may improve the identification of ideators most likely to make an attempt, enabling the deployment of targeted early interventions.

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.

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.

Examining the link between weight suppression and non-suicidal self-injurious behaviors

BACKGROUND

Given the negative consequences of excess weight, a large portion of the US population is seeking to obtain and maintain weight loss. Weight Suppression (WS) represents the difference between previous highest adult weight and current weight and may have negative psychological consequences. The current study examined the link between WS and lifetime non-suicidal self-injurious (NSSI) behavior and explored indirect effects in this link using survey data in two large samples.

METHODS

Sample 1 included 1011 college students (67% female, mean age = 19 years); Sample 2 included 2461 participants from an epidemiological study (68% female, mean age = 34 years). Models of direct and indirect effects were tested in MPlus using bootstrapping.

RESULTS

As hypothesized, greater WS was associated with increased likelihood of lifetime NSSI in both samples (OR = 1.05 and 1.02). In both samples, significant indirect effects of drive for thinness (Total R2 = 0.06 and 0.09) and depressive symptoms (Total R2 = 0.13 and 0.29) accounted for this association. Alternative models in which the indirect effect of WS was tested in associations between drive for thinness or depressive symptoms and NSSI were not supported.

CONCLUSION

Results suggest that the link between WS and lifetime NSSI may be accounted for by eating or mood-related pathology. Future research should test whether addressing associated eating and mood problems would eliminate the link between WS and NSSI as a means for reducing suicide risk.

Factors associated with suicide: Case-control study in South Tyrol

BACKGROUND

As suicide is related to many factors in addition to psychiatric illness, broad and comprehensive risk-assessment for risk of suicide is required. This study aimed to differentiate nondiagnostic risk factors among suicides versus comparable psychiatric patients without suicidal behavior.

METHODS

We carried out a pilot, case-control comparison of 131 cases of suicide in South Tyrol matched for age and sex with 131 psychiatric controls, using psychological autopsy methods to evaluate differences in clinically assessed demographic, social, and clinical factors, using bivariate conditional Odds Risk comparisons followed by conditional regression modeling controlled for ethnicity.

RESULTS

Based on multivariable conditional regression modeling, suicides were significantly more likely to have experienced risk factors, ranking as: [a] family history of suicide or attempt≥[b] recent interpersonal stressors≥[c] childhood traumatic events≥[d] lack of recent clinician contacts≥[e] previous suicide attempt≥[f] non-Italian ethnicity, but did not differ in education, marital status, living situation, or employment, nor by psychiatric or substance-abuse diagnoses.

CONCLUSIONS

Both recent and early factors were associated with suicide, including lack of recent clinical care, non-Italian cultural subgroup-membership, familial suicidal behavior, and recent interpersonal distress.

The role of stressful life events preceding death by suicide: Evidence from two samples of suicide decedents

Stressful life events (SLEs) are associated with increased risk for suicidal behavior. Less is known regarding the intensity of SLEs and how this may vary as a function of suicide attempt history. As a large percentage of suicide decedents do not have a history of suicidal behavior, SLEs precipitating suicide may help characterize suicidality in this understudied population. This paper examines the intensity, number, and accumulation of SLEs preceding death by suicide among decedents with varying suicide attempt histories. Suicide attempts, SLEs, and suicide methods were examined in two samples: 62 prison-based and 117 community-based suicide decedents. Regression was used to compare the level of stressor precipitating death by suicide in decedents who died on a first attempt versus multiple previous attempts. A non-significant trend was observed in the prison population which was supported by significant findings in the community-based sample. Decedents who died on a first attempt experienced a stressor of a lower magnitude when compared to decedents with multiple previous suicide attempts. We discuss the implications of these findings in relation to the stress-diathesis model for suicide.

The association between suicide and the utilization of mental health services in South Tirol, Italy: a psychological autopsy study

AIMS

The aim of the present study was to investigate potential differences between suicide decedents who had contact with a psychologist or psychiatrist before committing suicide and those individuals who had not had previous contact with a mental health professional prior to ending their lives.

METHODS

Psychological autopsy interviews (N = 396) were conducted for individuals who died by suicide between 1997 and 2007 in South Tirol, Italy.

RESULTS

The study found that suicide decedents known to mental health professionals were more frequently women and more frequently unemployed or with unstable employment. These decedents were significantly more likely than those unknown to mental health professionals to have a family history of mental illness, one or more past suicide attempts, and more frequent substance abuse, and likely to have frequent alcohol abuse. They more often had visited a physician in the last four weeks before dying and more frequently complained about psychological symptoms. In the prediction of group membership, individuals whom were known to mental health professionals prior to their suicidal act were 3 times more likely to have a family history of mental illness, 5.8 times more likely to have one past suicide attempt, 9.7 times more likely to have two or more past suicide attempts and 3.5 times more likely to have visited a physician in the four weeks prior to their death.

CONCLUSION

Our findings indicate that suicide decedents who had contact with mental health services can be distinguished from those who were not known to mental health professionals.

Sociodemographic and clinical differences between suicide ideators and attempters: a study of mood disordered patients 50 years and older

Our study sought to characterize mood disordered suicide ideators and attempters 50 years and older admitted to a psychiatric ward either for a recent suicide attempt or for ongoing suicidal ideation. We enrolled 50 patients with suicide ideation consecutively admitted to an inpatient department and 50 patients admitted for a suicide attempt made in the last 48 hours. Suicide attempters more frequently had low social support and an age of onset of mood disorder of 46 years and older, and less frequently had a history of suicidal behaviors in the family members and pharmacological treatment, despite the fact that the groups did not differ with regard to antidepressants prescribed. The groups were not distinguishable based on several variables assumed to be risk factors for suicide behavior, such as proximal life events and stressors or alcohol use disorders. In both samples, comorbidity with organic diseases, the presence of stressful life events in the past 12 months, and a diagnosis of major depression were frequently reported. In conclusion, the presence of low social support and the absence of a pharmacotherapy may increase suicidal behaviors in patients at risk.

Personality disorders and health problems distinguish suicide attempters from completers in a direct comparison

BACKGROUND

Whether suicide attempters and completers represent the same population evaluated at different points along a progression towards suicide death, overlapping populations, or completely different populations is a problem still unresolved.

METHODS

446 Adult suicide attempters and knowledgeable collateral informants for 190 adult suicide probands were interviewed. Sociodemographic and clinical data was collected for both groups using semi-structured interviews and structured assessments. Univariate analyses and logistic regression models were conducted to explore the similarities and differences between suicide attempters and completers.

RESULTS

Univariate analyses yielded significant differences in sociodemographics, recent life events, impulsivity, suicide intent, and distribution of Axis I and II disorders. A logistic regression model aimed at distinguishing suicide completers from attempters properly classified 90% of subjects. The most significant variables that distinguished suicide from attempted suicide were the presence of narcissistic personality disorder (OR=21.4; 95% CI=6.8-67.7), health problems (OR=20.6; 95% CI=5.6-75.9), male sex (OR=9.6; 95% CI=4.42-20.9), and alcohol abuse (OR=5.5; 95% CI=2.3-14.2).

LIMITATIONS

Our study shares the limitations of studies comparing suicide attempters and completers, namely that information from attempters can be obtained from the subject himself, whereas the assessment of completers depends on information from close family or friends. Furthermore, different semi-structured instruments assessed Axis I and Axis II disorders in suicide attempters and completers. Finally, we have no data on inter-rater reliability data.

CONCLUSIONS

Suicide completers are more likely to be male and suffer from alcohol abuse, health problems (e.g. somatic illness), and narcissistic personality disorder. The findings emphasize the importance of implementing suicide prevention programs tailored to suicide attempters and completers.

Sexuality and suicidality: matched-pairs analyses reveal unique characteristics in non-heterosexual suicidal behaviors

The present findings offer new perspectives on differences between suicide-risk heterosexuals and non-heterosexuals (lesbian, gay, bisexual, and questioning: LGBQ). Results from an anonymous online survey, employing standardized scales, showed that LGBQ participants reported significantly greater suicide-risk than heterosexuals. Seventy-nine matched pairs of suicide-risk LGBQ and heterosexuals were examined by individual suicide risk factors. Results showed no significant differences on separate measures of suicidal ideation; however, LGBQ participants were more likely to report suicide attempts, disclosure of suicidal intentions, and prediction of future suicide attempts. The LGBQ group also indicated greater likelihood of going online to develop new personal relationships. Multiple regression modeling was conducted to guide outreach and support efforts, revealing unique factors predicting help-seeking denial of suicide-risk LGBQ. Implications include the importance of online support and considering sexual minorities not just as a potential high-risk group, but also as a population with unique suicide risks and behaviors.

Suicide by cop: clinical risks and subtypes

This study examines whether clinical classification schemes from general suicide research are applicable for cases of suicide by cop (SbC) and whether there are indicators as to why the police might be engaged in the suicide. Using archival law enforcement data, 13 clinical risks were examined among 68 cases of SbC using exploratory factor analysis and k-means cluster analysis. Three subtypes of SbC cases emerged: Mental Illness, Criminality, and Not Otherwise Specified. The subtypes varied significantly on their levels of mental illness, substance use, and criminal activity. Findings suggest that reducing fragmentation between law enforcement and mental health service providers might be a crucial goal for suicide intervention and prevention, at least among cases of SbC.

Understanding suicide risk: identification of high-risk groups during high-risk times

BACKGROUND

The assessment of suicide risk is a complex task for mental health professionals. Certain demographic groups are associated with completed suicide including males, divorced adults, and Caucasians. However, demographic variables alone provide a crude assessment of suicide risk. Psychiatric diagnosis and recent life events might improve the identification of high-risk individuals.

METHOD

The current study evaluated 148 individuals who died by suicide compared with 257 adults who died suddenly from accidents or medical problems. Psychological autopsy was used to assess Axis I psychiatric diagnosis and recent stressful life events.

RESULTS

Suicide completers were significantly more likely than comparison subjects to have a depressive disorder, a substance abuse disorder, and to have experienced interpersonal conflict in the months leading up to their death. A discriminant function analysis revealed that the combination of demographic variables, recent stressful life events, and psychiatric diagnoses best discriminated between suicide completers and comparison subjects.

CONCLUSIONS

Proper assessment of suicide risk should include a comprehensive evaluation of demographic characteristics, recent life stressors, and psychiatric diagnosis.

Factors related to admission of psychiatric patients to medical wards from the general hospital emergency department: a 3-year study of urgent psychiatric consultations

OBJECTIVE

Emergency Rooms (ER) of Emergency Departments (ED) in General Hospitals (GH) have a role in providing for psychiatric evaluation. The aims of the present study were to examine the decision-making process of consultation psychiatry at the GH-ER and to analyze the differences between psychiatric patients admitted to a medical ward with those admitted to the psychiatry unit and those who are discharged from the ER.

METHOD

Over a period of 3 years, psychiatric consultations requested by ER of ED physicians to the GH Psychiatric service were recorded by using a form to describe epidemiological and clinical data on the consultation process.

RESULTS

Of 1,962 psychiatric consultations, most regarded subjects who had had previous psychiatric contacts (76.2%) and at least one psychiatric admission (53.6%), and were currently cared for by the Mental Health Services (51.1%). Neurotic/stress-related syndromes (27.98%), schizophrenia (27.67%), and personality disorders (21.81%) were the most frequent ICD-10 diagnoses. The psychiatrist's disposal was to discharge the patient in 49.9% cases, to admit him/her to medical wards of the GH (MGH; 26.9%) or to the acute inpatient psychiatric ward (AIP; 23.1%). MGH group statistically differed from AIP group for being female (p < 0.01), older (p < 0.01), more likely having an ICD-10 diagnosis of neurosis/stress-related syndromes (p < 0.01) or organic mental disorder (p < 0.01), and less likely having a diagnosis of schizophrenia (p < 0.01), being in charge of the Mental Health Services (p < 0.01), and having had previous psychiatric admissions (p < 0.01). These results were confirmed by logistic regression analysis.

CONCLUSIONS

The study shows that the medical wards of the General Hospital are a significant entry-point for providing psychiatric care of patients with ICD-10 neurotic and stress-related syndromes, even if without specific medical problems.
