Examining the Associations Between Substance Misuse and Suicide Bereavement.

Focusing on the understudied question of substance misuse among suicide bereaved adults we investigated patterns of binge drinking and non-prescribed drug use among a recently bereaved sample (n = 1,132). Comparing our respondents to the non-bereaved, those in the 2022 National Survey of Drug Use and Health (n = 71,369), we did not find heightened problematical substance misuses among our respondents. With t-tests and multiple regression analyses we examined whether binge drinkers and non-prescribed drug users had heightened levels of grief difficulties, PTSD, self-blaming and depression compared to others not bingeing or using non-prescribed drugs. Results showed binge drinkers had more of all these grieving problems when important confounding variables were also considered. Analysis of the demographic correlates of bingeing showed them dimly aware of their own additional grieving and substance misusing problems. Since 75% indicated being under the care of counseling professionals, this represents an important opportunity for psycho-educational helping.

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.

The role of depression and use of alcohol and other drugs after partner suicide in the association between suicide bereavement and suicide: cohort study in the Danish population.

BACKGROUND: Although suicide bereavement is associated with suicide and self-harm, evidence regarding mechanisms is lacking. We investigated whether depression and substance use (alcohol and/or other drugs) explain the association between partner suicide bereavement and suicide. METHODS: Linkage of nationwide, longitudinal data from Denmark for the period 1980-2016 facilitated a comparison of 22 668 individuals exposed to bereavement by a partner's suicide with 913 402 individuals bereaved by a partner's death due to other causes. Using causal mediation models, we estimated the degree to which depression and substance use (considered separately) mediated the association between suicide bereavement and suicide. RESULTS: Suicide-bereaved partners were found to have a higher risk of suicide (HRadj = 1.59, 95% CI 1.36-1.86) and of depression (ORadj 1.16, 95% CI 1.09-1.25) when compared to other-bereaved partners, but a lower risk of substance use (ORadj 0.83; 95% CI 0.78-0.88). An increased risk of suicide was found among any bereaved individuals with a depression diagnosis recorded post-bereavement (ORadj 3.92, 95% CI 3.55-4.34). Mediation analysis revealed that depression mediated 2% (1.68%; 95% CI 0.23%-3.14%; p = 0.024) of the association between suicide bereavement and suicide in partners when using bereaved controls. CONCLUSIONS: Depression is a partial mediator of the association between suicide bereavement and suicide. Efforts to prevent and optimize the treatment of depression in suicide-bereaved people could reduce their suicide risk. Our findings might be conservative because we did not include cases of depression diagnosed in primary care. Further work is needed to understand this and other mediators.

The impact of relationship type and closeness on mental health following suicide loss.

BACKGROUND: Most research investigating the effect of suicide on loss survivors has been limited to first-degree family members. Few studies examine the impact of suicide on others outside the immediate family and the influence of relationship type and closeness on mental health. METHODS: This study used data from a sample obtained through random digit dialing (n = 805) to assess exposure to suicide loss, relationship types, perceived closeness, and mental health symptoms (prolonged grief, depression, anxiety, and posttraumatic stress disorder). RESULTS: Familial status, friend status, and higher perceived closeness were associated with prolonged grief, depression, and posttraumatic stress disorder, with the strongest adjusted associations observed for posttraumatic stress disorder and prolonged grief. In general, the magnitude of adjusted standardized associations for closeness and mental health symptoms was stronger than those observed for familial status and mental health symptoms and friend status and mental health symptoms. CONCLUSION: Closeness, familial status, and friend status are associated with mental health symptoms experienced after suicide loss, but the magnitude of associations was strongest for closeness. Future studies should examine perceived closeness in addition to other factors related to relationship type and dynamics to assess the complexities of suicide bereavement reactions.

Impacts of exposure to suicide of a military colleague from the lived experience of veterans: Informing postvention responses from a military cultural perspective.

Although exposure to the suicide death of a military colleague has been shown quantitatively to increase suicide risk factors among veterans, there are very few studies where veterans have been asked about this experience. This article presents a qualitative analysis of 38 interviews with U.S. veterans with exposure to the suicide death of a military colleague in past war operations. Participants described the impact of exposure in relation to the military context and official response to the death, which had long-term ramifications. Our findings suggest suicide prevention and postvention responses for veterans should be informed by the lived experience of veterans, including those for whom this experience occurred significantly in the past, as the impacts of different military policies and practices in response to suicide deaths over time are relevant to the impact of exposure to death of a military colleague in the short and long term.

The Effects of Suicide Exposure on Mental Health Outcomes Among Post-9/11 Veterans: Protocol for an Explanatory, Sequential, Mixed Methods Study.

BACKGROUND: The toll associated with suicide goes well beyond the individual who died. This study focuses on a risk factor for veteran suicide that has received little previous empirical attention-exposure to the suicide death of another person. OBJECTIVE: The study's primary objective is to describe the mental health outcomes associated with suicide exposure among veterans who served on active duty after September 2001 ("post-9/11"). The secondary objective is to elucidate why some veterans develop persistent problems following suicide exposure, whereas others do not. METHODS: This is an explanatory, sequential, mixed methods study of a nationally representative sample of post-9/11 veterans enrolled in Department of Veterans Affairs (VA) health care. Our sampling strategy was designed for adequate representation of female and American Indian and Alaska Native veterans to allow for examination of associations between suicide exposure and outcomes within these groups. Primary outcomes comprise mental health problems associated with trauma and loss (posttraumatic stress disorder and prolonged grief disorder) and suicide precursors (suicidal ideation, attempts, and planning). Data collection will be implemented in 3 waves. During wave 1, we will field a brief survey to a national probability sample to assess exposure history (suicide, other sudden death, or neither) and exposure characteristics (eg, closeness with the decedent) among 11,400 respondents. In wave 2, we will include 39.47% (4500/11,400) of the wave-1 respondents, stratified by exposure history (suicide, other sudden death, or neither), to assess health outcomes and other variables of interest. During wave 3, we will conduct interviews with a purposive subsample of 32 respondents exposed to suicide who differ in mental health outcomes. We will supplement the survey and interview data with VA administrative data identifying diagnoses, reported suicide attempts, and health care use. RESULTS: The study began on July 1, 2022, and will end on June 30, 2026. This is the only national, population-based study of suicide exposure in veterans and the first one designed to study differences based on sex and race. Comparing those exposed to suicide with those exposed to sudden death for reasons other than suicide (eg, combat) and those unexposed to any sudden death may allow for the identification of the common and unique contribution of suicide exposure to outcomes and help seeking. CONCLUSIONS: Integrating survey, qualitative, and VA administrative data to address significant knowledge gaps regarding the effects of suicide exposure in a national sample will lay the foundation for interventions to address the needs of individuals affected by a suicide death, including female and American Indian and Alaska Native veterans.

Investigating risk of self-harm and suicide on anniversaries after bereavement by suicide and other causes: a Danish population-based self-controlled case series study.

AIMS: To investigate mechanisms of suicide risk in people bereaved by suicide, prompted by observations that bereaved people experience higher levels of distress around dates of emotional significance. We hypothesised that suicide-bereaved first-degree relatives and partners experience an increased risk of self-harm and suicide around dates of (i) anniversaries of the death and (ii) the deceased's birthday, compared with intervening periods. METHODS: We conducted a self-controlled case series study using national register data on all individuals living in Denmark from 1 January 1980 to 31 December 2016 and who were bereaved by the suicide of a first-degree relative or partner (spouse or cohabitee) during that period, and who had the outcome (any episode of self-harm or suicide) within 5 years and 6 weeks of the bereavement. We compared relative incidence of suicidal behaviour in (i) the first 30 days after bereavement and (ii) in the aggregated exposed periods (6 weeks either side of death anniversaries; 6 weeks either side of the deceased's birthdays) to the reference (aggregated unexposed intervening periods). As an indirect comparison, we repeated these models in people bereaved by other causes. RESULTS: We found no evidence of an elevated risk of suicidal behaviour during periods around anniversaries of a death or the deceased's birthdays in people bereaved by suicide (adjusted incidence rate ratio [IRRadj] = 1.00; 95% confidence interval [CI] = 0.87-1.16) or other causes (IRRadj = 1.04; 95% CI = 1.00-1.08) compared with intervening periods. Rates were elevated in the 30 days immediately after bereavement by other causes (IRRadj: 1.95, 95% CI: 1.77-2.22). CONCLUSIONS: Although people bereaved by suicide are at elevated risk of self-harm and suicide, our findings do not suggest that this risk is heightened around emotionally significant anniversaries. Bereavement care should be accessible at all points after a traumatic loss as needs will differ over the grief trajectory.

The Willingness to Intervene Against Suicide Enhanced Questionnaire.

The purpose of this study was to test the reliability and validity of the Willingness to Intervene against Suicide Enhanced (WISE) questionnaire. The WISE is a revised version of the Willingness to Intervene against Suicide (WIS) questionnaire, which was based on the theory of planned behavior, and it has consistently predicted the intention to intervene with a suicidal individual. Evaluation of the WIS showed that it was internally consistent with adequate goodness-of-fit indices for three of the four scales. The subjective norms scale did not meet the goodness-of-fit indices standard cutoff criteria. Due to this, the WIS questionnaire has been revised into the WISE. However, the dimensionality of these factors needed to be tested. College students (n = 824) completed an online survey to test the WISE. The data were analyzed using confirmatory factor analysis, reliability analysis, and multiple regression. The WISE was internally consistent, and the scales met acceptable criteria for goodness-of-fit indices. The WISE explained a range of variance in participants' intention to intervene from 12 to 40%.

Sexual Assault Victimization in Premature Female Mortalities: Evidence from the National Longitudinal Study of Adolescent to Adult Health.

Previous research has documented many behavioral problems associated with being a female victim of sexual assault, but little attention has been devoted to whether this experience might be related to premature mortalities. We investigated this utilizing the National Longitudinal Study of Adolescent to Adult Health survey, collected from over 10,000 adolescent females in 1995, whose premature deaths (n = 65) were noted in 2007 in National Death Index records. Significant associations were found between females with a substance misuse history and their premature deaths, but not with being a sexual assault victim. The subset of respondents (n = 208) evincing both these characteristics showed significantly higher risks of dying prematurely, as did those females with early histories of drug misuse alone. Yet, adolescent females with histories of drug misuse who also attempted suicide (n = 214) did not show similar elevated risks of dying prematurely compared to others without these experiences. This exploratory evidence points to an affinity between both being a female sexual assault victim and having an early history of misusing drugs, putting such people at heightened risks for dying prematurely, suggesting the potential benefits of counseling and supportive services for those so affected.

The Role of Death Anxiety and Self-Esteem in Suicide Attitudes.

The persistent stigmatization of suicide calls for a careful examination of the thought processes involved in perceptions of suicide. Hence, the present study is the first to apply terror management theory (TMT) and use experimental methods to examine whether reminders of death lead to increased stigma towards suicide and whether self-esteem moderates these stigmatized reactions. Consistent with the predicted effect of the death anxiety and self-esteem hypothesis, findings revealed that, for respondents with low self-esteem, thinking about their own death led to more stigma, less willingness to intervene, and allocated less money to a suicide prevention organization as compared to those who did not think about death. Findings from this study could have important implications for how we understand the psychological underpinnings of stigma and the role of death anxiety in hostile attitudes and decreased altruism - especially for mental health professionals working with individuals affected by suicide.

Increased rates of suicide ideation and attempts in rural dwellers following the SARS-CoV-2 pandemic.

PURPOSE: Those factors identified to increase the risk of suicide in rural dwellers were exacerbated by the SARS-CoV-2 pandemic, specifically economic factors, substance use, access to health care, and access to lethal weapons. Because the effects of SARS-CoV-2 on suicide ideation and attempts in rural populations have not been fully characterized in published literature, this study compares: (1) the rates of suicide ideation and attempts between the 6 months affected by SARS-CoV-2 to same months of the preceding year (3/18/2020-9/18/20; 3/18/2019-9/18/19), (2) demographics (ie, age, sex, residence, race, and ethnicity), and (3) the locations in which the encounters were billed (inpatient, outpatient, and emergency department). METHODS: Deidentified claims data associated with patient encounters billed for Suicide Ideation and Suicide Attempt were grouped based on time period and analyzed using descriptive statistics, incidence rate ratio (IRR), 2-sample t-test, chi-square test of association, or Fisher's exact test. FINDINGS: Suicidal ideation encounters increased in the 6 months post-SARS-CoV-2 when compared to the 6 months of the prior year (IRR = 1.19; P < .001). Males (IRR = 1.27, P < .001), those residing rural areas (IRR = 1.22, P = .01), and Black, non-Hispanic (IRR = 1.24, P = .024) were found to have increased rates of suicide ideation post-SARS-Cov-2. In adults, White, non-Hispanics (IRR = 1.16; P < .001) had increased rates of post-SARS-CoV-2. In the pediatric subset, those who were aged 14-17 (IRR = 1.50; P < .001), resided in rural areas (IRR = 1.61, P = .009), and idenitifed as Hispanic (IRR = 1.89; P = .037) or Black, non-Hispanic (IRR = 1.61, P = .009) had increased rates post-SARS-CoV-2. CONCLUSIONS: Our study identified rural dwellers to be at increased risk for suicide ideation.

Using Multiple Regression Analyses to Uncover Patterns of Correlates of Grief Problems, Depression and Suicidal Ideation Among Suicide Bereaved Individuals.

This analysis of a convenience sample survey of 195 suicide bereaved adults focuses on predictors of three important highly interrelated experiences among the suicide bereaved: grief problems, depression and suicidal thinking. Although each of these three experiences can be explained by a unique set of predictors, they share many commonalities. Several predictors stood out especially in either aggravating or alleviating these experiences: personal (or post-traumatic) growth, perceived social support, feelings of blameworthiness, perceived suicide stigma, years since loss and a respondent's mental health difficulties experienced prior to their suicide loss. We also review the clinical implications of these results.

Suicide knowledge and intention to intervene: college students.

Objective: The revised Willingness to Intervene against Suicide questionnaire and the Expanded Revised Facts on Suicide Quiz were employed to examine the relationship between college students' knowledge about suicide and intention to intervene. Participants: College students (n = 515) participated, a majority being women and Caucasian. Methods: Participants completed an online survey. Data were analyzed in SPSS. Results: College students have poor knowledge of suicide facts; however, this low level of accurate knowledge was not associated with intention to intervene with a suicidal person. Attitudes, subjective norms, perceived behavioral control, sex, and no previous suicide attempt were all significant predictors of intention to intervene. Conclusions: These results challenge the notion that one must be well-informed in order to intend to take action.

Growth and Hope after loss: How TAPS facilitates posttraumatic growth in those grieving military deaths.

We examined posttraumatic growth for 691 participants of the Tragedy Assistance Program for Survivors (TAPS). Peer mentors of bereaved individuals experienced greater posttraumatic growth (PTG) and reported higher psychological health than those who were non-peer mentors. Active involvement in TAPS and resilience consistently and positively predicted all types of PTG. These prediction models were far stronger (R2, AIC) for the suicide-bereaved sample than those bereaved by other causes, and post-hoc analyses suggest suicide-bereaved benefitted more than those bereaved by other causes from active participation in TAPS.

Proportion of suicides in Denmark attributable to bereavement by the suicide of a first-degree relative or partner: Nested case-control study.

OBJECTIVE: To provide the first estimates of the risk of suicide after bereavement by the suicide of any first-degree relative and the proportion of suicides in Denmark attributable to suicide bereavement. METHODS: We conducted a nationwide nested case-control study defining cases as all Danish-born individuals who died by suicide in Denmark between 01 January 1980 and 31 December 2016 (n = 32,248), age-matched to four living controls. Using three exposure categories (bereavement by the suicide of a relative [parent, offspring, sibling, and spouse/cohabitee]; non-suicide bereavement; no bereavement) and conditional logistic regression adjusted for pre-specified covariates we estimated the odds of exposure to suicide bereavement in cases versus controls. We tested whether associations differed for men and women, estimated the population attributable fraction (PAF) of suicides in our population at risk that could be attributed to a first-degree relative's suicide loss, and estimated the attributable fraction among the exposed (AFe). RESULTS: Suicide bereavement was associated with an increased odds of suicide when compared with no bereavement (ORadj2  = 2.90, 95% CI: 2.46-3.40) or non-suicide bereavement (ORadj2  = 1.48, 95% CI: 1.25-1.74). There was no evidence to support any interaction with sex. PAF (0.69%; 95% CI: 0.62%-0.77%) and AFe (60.12%; 95% CI: 53.19%-66.03%) estimates suggested that in Denmark 0.69% of suicides, and 60% of suicides among suicide-bereaved relatives, could be prevented if it was possible to address all factors increasing suicide risk in suicide-bereaved relatives. CONCLUSION: Suicide bereavement in relatives and partners contributes to at least one in 145 suicides in Denmark.

Suicide exposure experience screener for use in therapeutic settings: A validation report.

INTRODUCTION: A brief screener assessing experience of exposure to suicide for use in therapeutic settings is warranted. To examine the concurrent validity of such a screening tool, labeled as the Suicide Exposure Experience Screener (SEES), the associations of the two SEES items: (i) reported closeness with the person who died by suicide and (ii) perceived impact of suicide death with psychological distress are presented. METHODS: Five separate datasets comprising surveys from Australia, Canada, and the United States (Ncombined  = 7782) were used to provide evidence of concurrent validity of closeness and impact of suicide exposure. RESULTS: Overall, closeness and impact were significantly correlated with measures of global distress across five different datasets, showing small to medium effect sizes. Closeness and impact were also intercorrelated demonstrating a large effect size across all surveys. This report used cross-sectional data and comprised varied sample sizes across different datasets that influenced statistical significance of obtained effects and did not tease apart the roles of cumulative exposure of suicide and prolonged bereavement in experiencing global distress. CONCLUSION: The SEES has clinical utility in determining psychological distress in bereaved individuals and is recommended for use in therapeutic settings.

Exploring the Psychometric Properties of the Stigma of Suicide Scale Using a Sample of Adults Bereaved by Suicide and Suicide Attempt Survivors.

The Stigma of Suicide Scale (SOSS) is a measure of public attitudes toward suicide decedents, which makes it unique from other scales that measure more general attitudes toward suicide. The aim of this study was to further replicate and extend the reliability and factor structure of the SOSS (both long- and short form) in a sample of individuals directly impacted by suicide. This study also sought to identify factors that impact suicide attitudes unique to this sample. The sample included 312 participants who had personal experience with suicide. Results provided support for the oblique three-factor structure of the SOSS (stigma, isolation/depression, and glorification/normalization), with a superior model fit for the 16-item short form version. Correlates of suicide attitudes among individuals exposed to suicide included perceived relationship closeness to a suicide decedent, experience with both loss and attempt, and the sex of the suicide decedent.

Suicide Attitudes Among Suicide Loss Survivors and Their Adaptation to Loss: A Cross-Cultural Study in Japan and the United States.

Survivors' adaptation to a suicide loss is likely influenced by their attitudes toward suicide and their respective sociocultural contexts. Our study aimed to compare suicide attitudes and their association with depressive symptoms and sense of community safety in Japanese and American suicide loss survivors. A total of 193 Japanese survivors and 232 American survivors completed online surveys. The results show that Japanese survivors tended not to consider suicide as an illness or to recognize that others understood their experience but were more likely than American survivors to consider suicide as justifiable. Regression analyses indicated that taking suicide as a right was associated with depressive symptoms. Further, their sense of being understood by others was positively correlated with perceived community safety in both samples, but justifying suicide and considering it to be an illness was positively related to perceived community safety only among Japanese survivors.

Experiences of hospitalization for suicide ideation and suicide attempt in gender diverse adults.

INTRODUCTION: This study sought to investigate general perceptions of suicide-related hospital-based care that Transgender/Gender Diverse (TGD) adults have experienced as well as correlates of their perceived usefulness of this care. METHODS: Data were collected via a cross-sectional online survey of N = 3718 self-identified TGD individuals. Single-item self-report measures of all constructs of interest were used. RESULTS: A total of n = 1056 participants indicated hospitalization for either a past suicide attempt (SA) or suicidal ideation (SI). Irrespective of being hospitalized for SI or SA, perceived usefulness of hospital-based care was low with 50% or more of participants rating their care as some degree of unhelpful. Older age, general trust in mental healthcare providers, and voluntary admission were related to higher perceived helpfulness of care for both SI and SA admissions. Higher pride in TGD identity was positively related to perceived helpfulness of care but only for admissions related to SAs. CONCLUSION: Improving perceived usefulness of hospital-based care may be important for improving subsequent suicide-related help-seeking. Increasing training and provision of care that improves trust with mental healthcare providers and potentially reduces need for involuntary admission may help improve hospital-based, suicide-related care in TGD adults.
