Effect of the Coronavirus Disease 2019 Pandemic on Suicide-Related Trauma Burden at a Level 1 Trauma Center

INTRODUCTION

In March 2020, the first coronavirus disease 2019 (COVID-19) cases were reported in New York and a stay-at-home order was enacted soon after. Social isolation combined with pandemic-related stressors profoundly affected mental health. We hypothesize that there was an increase in violent suicide attempt during the COVID-19 pandemic lockdown compared to previous years.

METHODS

We queried our institutional trauma registry for total number of trauma activations and identified adult patients with International Classification of Diseases-10 diagnosis of intentional self-harm. We compared incidence during the lockdown to corresponding time periods from previous years. Demographic and injury characteristics were compared, as were outcomes such as mortality.

RESULTS

We observe a significant uptrend in patients requiring trauma intervention after suicide attempts from July 2019 through July 2020 (r = 0.8, P < 0.001) despite a significant downtrend in trauma volume at our institution during the same period (r = ‒0.7, P = 0.003). Although not statistically significant, patients attempting violent suicide during lockdown were more likely to have preexisting psychiatric diagnoses, to live alone, to have injury severity score >9, and to require surgical intervention. Three COVID-period patients died in the emergency room compared to zero in the comparison group.

CONCLUSION

Our data show a rise in violent suicide attempts during the pandemic lockdown despite an overall decrease in trauma volume. The ramifications of a stay-at-home order seem to have the most profound impact on individuals with preexisting mental health disease. Early establishment of mental health outreach programs may mitigate the reverberating psychosocial consequences of a pandemic.

Differences in Influencing Factors Between Non-suicidal Self-Injury and Suicide Attempts in Chinese Adolescents: The Role of Gender

INTRODUCTION

Non-suicidal self-injury (NSSI) and suicide attempts (SA) are common in adolescents and are important risk factors for suicide deaths. They are related to various psychosocial, behavioral, and biological factors. We aimed to compare the differences on psychological behavior problem and family environment characteristics between NSSI and SA, and the role of gender.

METHODS

A multi-center population-based survey was conducted in 29 schools across 4 provinces in China. A total of 14,500 urban and rural adolescents in grades 7-12 completed a structured questionnaire to report their sociodemographic information, psychological and behavioral characteristics, childhood maltreatment, parent-child relationships, NSSI, and SA. Post-hoc tests, pairwise comparisons, and multinomial logistic regression analyses were conducted to explore the differences and similarities between subjects who had engaged in NSSI and SA.

RESULTS

The prevalence of NSSI and SA were 27.3 and 4.9%, respectively, and the co-occurrence of these two behaviors (NSSI + SA) was reported to 2.8%. The NSSI + SA group scored the highest on all study variables, followed by the SA-only group, the NSSI-only group, and the non-self-harm group (p < 0.001). Compared with the non-self-harm group, adolescents who reported either NSSI or SA scored significantly higher on all study variables (p< 0.0083). The comparison between other self-harm groups, this difference have varied in all research variables.

CONCLUSION

The current study indicate that psychological, behavioral, and family relationships profiles of Chinese adolescents with SA and NSSI are similar, but the measured problematic characteristics were more severe in suicide attempters. In the future, it's necessary to pay more attention to adolescents with more serious psychological and behavioral problems to prevent and early intervene in their self-harm, and actively explore gender differences.

Testing the Influence of Brooding and Anger Rumination on the Association Between Suicidal Outcomes and BPD Features in Undergraduate Students

Borderline personality disorder (BPD) symptoms and suicidal behaviors are prevalent among undergraduate students. Although rumination contributes to self-destructive behaviors in BPD, less research examines the role of rumination in distinct suicidal outcomes among individuals with BPD features instead focusing more on self-destructive behaviors as a latent variable. The present study examined the main and interactive effects of BPD features and two forms of rumination (brooding and anger) in the prediction of suicide-related outcomes (ideation and attempts) among college students. Participants (N = 181 undergraduate students, overrecruited for BPD features; 55.2% female) reported their lifetime suicide risk, brooding rumination, anger rumination, and BPD features. Brooding rumination and BPD features were associated with suicidal ideation. Anger rumination was not associated with suicide-related outcomes. Findings suggest that brooding rumination is a potential intervention target for suicidal ideation in undergraduate students whereas further research is required to determine the association between anger rumination and suicidal ideation and attempts.

Suicidal ideation and behavior in youth in low- and middle-income countries: A brief review of risk factors and implications for prevention

Although global rates of suicide have dropped in the last 30 years, youth in low- and middle-income countries (LMICs) continue to be highly represented in suicide statistics yet underrepresented in research. In this review we present the epidemiology of suicide, suicidal ideation, and suicide attempts among youth in LMICs. We also describe population-level (attitudes toward suicide, socioeconomic, and societal factors) and individual-level clinical and psychosocial risk factors, highlighting specific considerations pertaining to youth in LMICs. These specific considerations in risk factors within this population can inform how multi-level prevention strategies may be targeted to meet their specific needs. Prevention and intervention strategies relying on the stepped-care framework focusing on population-, community-, and individual level targets while considering locally- and culturally relevant practices are key in LMICs. In addition, systemic approaches favoring school-based and family-based interventions are important among youth. Cross-culturally adapted multimodal prevention strategies targeting the heterogeneity that exists in healthcare systems, suicide rates, and risk factors in these countries should be accorded a high priority to reduce the burden of suicide among youth in LMICs.

Association of thyroid-stimulating hormone and lipid levels with suicide attempts among adolescents with major depressive disorder in China

OBJECTIVES

Evidence suggested that thyroid-stimulating hormone (TSH) and lipid levels were associated with major depressive disorder (MDD). However, its role in suicide attempts in adolescents with MDD was unclear. This investigation was to probe into the relationship between TSH, lipid levels, and attempted suicide in adolescents with MDD.

METHODS

A total of 179 adolescents with MDD were included from January 2021 to January 2022. Socio-demographic data and clinical data were obtained through self-made questionnaires. TSH and lipid levels were analyzed by a recognized laboratory. The Epidemiological Studies Depression Scale (CES-D) was used to assess the severity of depression. Questions about whether there was a behavior of suicide attempts were completed through conversation interviews.

RESULTS

Results showed that the CES-D total score, TSH, and low-density lipoprotein cholesterol (LDL-C) of suicide attempters were significantly higher than those of non-suicide attempters. Ordinary family relationships were more likely to attempt suicide than good family relationships. The CES-D total score, ordinary family relationships, TSH and LDL-C were still significant in binary logistic regression, with an adjusted odds ratio (OR) of 1.04, 3.42, 5.14, and 1.76, respectively. The area under the receiver operating characteristic (ROC) curve showed that the area under the ROC curve (AUC) ranged from 0.60 to 0.74.

CONCLUSION

Suicide attempts are common among adolescents with MDD and were associated with CES-D total score, ordinary family relationships, TSH, and LDL-C. Given the association between suicide attempts and TSH and LDL-C, the dynamic changes in TSH and LDL-C levels should be detected regularly.

Longitudinal Development of Reasons for Living and Dying With Suicide Attempters: A 2-Year Follow-Up Study

BACKGROUND

Clinical interventions for patients after a suicide attempt might include a focus on Reasons for Living (RFL) and/or Reasons for Dying (RFD). The present study examined the longitudinal development of RFL and RFD in patients with and without a suicide-specific intervention - the Attempted Suicide Short Intervention Program (ASSIP).

METHODS

In this secondary analysis of a 2-year follow-up randomized controlled study, participants completed the Suicide Status Form II to assess RFL and RFD, at baseline, as well as at 6-, 12-, 18-, and 24-months follow-up. Growth models and latent class analysis were used to investigate longitudinal developments in RFL and RFD. Regression models were used to test the association between RFL, RFD and suicidal reattempts and ideation.

RESULTS

Cross-sectionally and longitudinally, RFD, but not RFL, were associated with suicide reattempts and suicidal ideation. The number of RFD decreased significantly across the 24 month period (from 1.90 at t1 to 1.04 at t5 in the control group and from 2.32 at t1 to 0.51 at t5 in the intervention group), and this decrease was stronger (b = -0.02; p = 0.004) in the ASSIP group than in the control group. There was no overall change in RFL. Three latent trajectories of RFD were identified: a decreasing (n = 77), a steady high (n = 17) and a trajectory with first increasing and then decreasing RFD (n = 26). The proportion of patients in the ASSIP intervention was highest in the decreasing trajectory and lowest in the steady high trajectory. Patients in the steady high trajectory were characterized by worse mental health and fewer social obligations (partner, children) at baseline.

CONCLUSION

The results confirm the importance of RFD within the suicidal process and show that the number of RFD can be further reduced over the period of 24 months with short interventions such as ASSIP. The relevance of number of RFL in the suicidal process, as protective factor, was not confirmed. In the subgroup of patients whose RFD did not decrease over a long period of time, there is a particularly high risk of suicidal ideation/behavior. Clinical interventions should focus more closely on RFD, their etiology and maintenance.

Prevalence and Predictors of Toxoplasma gondii Infection in Psychiatric Inpatients in Fars Province, Southern Iran

BACKGROUND

Psychiatric patients are at increased risk of exposure to Toxoplasma gondii infection, which may be linked to their living facilities and behaviors. Limited knowledge on the prevalence of T. gondii infection and its associated risk factors in psychiatric patients are available to the international medical communities. Thus, the aim of the current study was to assess seroprevalence of T. gondii and its associated risk factors in psychiatric inpatients in Fars Province, southern Iran.

METHODS

This cross-sectional study was carried out on psychiatric patients hospitalized in Ibn Sina Hospital affiliated to Shiraz University of Medical Sciences, Fars Province, southern Iran, March to July 2021. Blood samples were collected from 318 psychiatric patients and assessed for the detection of IgG against T. gondii using enzyme-linked immunosorbent assay (ELISA). Moreover, structured questionnaires were completed for the participants at the time of sampling. Logistic regression analysis was used to assess possible associations between the latent toxoplasmosis and the variables.

RESULTS

The overall seroprevalence of anti-T. gondii IgG in psychiatric inpatients was 22.3% (71/318; 95% CI = 17.9-27.3). Multivariate analyses revealed that age > 30 years [adjusted odds ratio (AOR) = 2.24, 95% CI = 1.10-4.60, p = 0.03], contact with cats (AOR = 2.52, 95% CI = 1.14-5.58, p = 0.03), raw vegetable consumption (AOR = 3.65, 95% CI = 1.74-7.65, p = 0.001), raw/undercooked meat consumption (AOR = 4.30, 95% CI = 1.47-12.63, p = 0.008), suicide attempt (AOR = 3.77, 95% CI = 1.58-8.97, p = 0.003) and cigarette smoking history (AOR = 0.38, 95% CI = 0.17-0.83, p = 0.02) were independent risk factors for T. gondii infection.

CONCLUSION

The current results demonstrated that contact with cats, raw vegetable consumption and raw/undercooked meat consumption were independent risk factors for T. gondii seropositivity. Moreover, the current study showed significant associations between seropositivity of T. gondii and suicide attempts as well as negative associations between seropositivity of T. gondii and cigarette smoking in psychiatric inpatients using multivariate logistic regression.

Predicting Sex-Specific Nonfatal Suicide Attempt Risk Using Machine Learning and Data From Danish National Registries

Suicide attempts are a leading cause of injury globally. Accurate prediction of suicide attempts might offer opportunities for prevention. This case-cohort study used machine learning to examine sex-specific risk profiles for suicide attempts in Danish nationwide registry data. Cases were all persons who made a nonfatal suicide attempt between 1995 and 2015 (n = 22,974); the subcohort was a 5% random sample of the population at risk on January 1, 1995 (n = 265,183). We developed sex-stratified classification trees and random forests using 1,458 predictors, including demographic factors, family histories, psychiatric and physical health diagnoses, surgery, and prescribed medications. We found that substance use disorders/treatment, prescribed psychiatric medications, previous poisoning diagnoses, and stress disorders were important factors for predicting suicide attempts among men and women. Individuals in the top 5% of predicted risk accounted for 44.7% of all suicide attempts among men and 43.2% of all attempts among women. Our findings illuminate novel risk factors and interactions that are most predictive of nonfatal suicide attempts, while consistency between our findings and previous work in this area adds to the call to move machine learning suicide research toward the examination of high-risk subpopulations.

Adverse Childhood Experiences and Suicidality and Self-Harm in Persons in Secure Forensic Care

Prior research suggests a greater degree of suicidality and self-harm behavior in those involved with criminal justice and forensic mental health systems. Such individuals also evidence increased exposure to early childhood adversity, which is often associated with suicide risk. Other significant predictors of suicidality have been noted within forensic populations, however, including indicators of specific psychopathology and situational and demographic factors. These populations present with overlapping risk factors that remain underexamined. In the current study, 182 persons residing in secure forensic psychiatric care following incidents of illegal and aggressive behavior were evaluated. Adverse childhood experiences and other empirically derived potential predictors of suicide attempts and self-harm were examined via binomial logistic regression. Findings indicate frequent experiences of early adversity across participants, and that a combination of race, individual adverse childhood experiences, number of biological children, and diagnoses of either posttraumatic stress disorder or borderline personality disorder were significant predictors of suicide attempts, self-harm behavior, and first hospitalization resulting from a suicide attempt. Clinical and research implications are discussed.

A story of recovery from the dangers of drug use and psychosis

WHAT IS KNOWN ON THE SUBJECT?: The effectiveness of Clozapine for some people suffering from schizophrenia. The use of street drugs as self-medication and a coping mechanism. WHAT DOES THE PAPER ADD TO EXISTING KNOWLEDGE?: The difficulties of treating someone with addiction problems and psychotic symptoms. Allowing them time in hospital only once they are off the drugs. Once I was in the recovery ward, I knew I wouldn't go back to drug use. Describing my own experience of drug use and suicidal thinking as an expression of frustration at not being able to make the changes I needed and wanted. To then finally make that change and to embrace a better life, when things started to move forward I made a commitment to do all I could to stay well. I knew what I wanted. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: This story describes a lack of action from the mental health services. The psychosis was considered to be caused by the drug use and nothing could be done until the drug use had stopped. I believe more could have been done to provide a safe space for rehabilitation and eventually recovery. The recovery ward that I was admitted to give me 16 months to turn my life around, services like these can be a lifesaver. Hospitals can be so quick to discharge patients that they end up coming straight back, and I was given the time and support I needed to make big changes. ABSTRACT: Introduction This is a story of a very difficult time in my life. A time when I got stuck into heavy drug use and a time when I was begging the mental health services for help. The suicide attempts show that I was unable to see a life for myself, but it includes the recovery, the commitment I made to myself to live a good life. I think it shows both the desperation of suffering with schizophrenia but also some optimism that people who suffer can find a meaningful occupation. Aim The aim is to offer hope, but also highlight some of the fears. There is more to be done to offer help and hope to those struggling with mental health and drug problems. Maybe with the correct care, people can be treated for both addiction and psychosis. I had to quit the drugs myself and only when I tried to kill myself did I receive any help. The drugs made me feel good about myself and the people around me, but living without them is a much better life. Narrative I wanted to give the first person account of being drawn into drug use and then wanting to quit. Many people feel a desire to quit but never get the will power or the help. I realised the drugs weren't giving me the high I wanted and decided to remove myself from the group and leave town. More people can be helped to believe in a life without drugs. Discussion and implications for practice Addiction is something that may never have a solution, but for many people with mental health problems it offers a way out of suffering. I actually felt much better about myself and life with the use of drugs. It gave me some control over my psychosis and lifted my mood, but in my story I had to realise myself I could do better without. More can be done to support people away from drugs and into work, I replaced the drugs with work and it has been a huge achievement. People need to know there is better for them.

Utilization of psychiatric services prior to suicide- a retrospective comparison of users with and without previous suicide attempts

INTRODUCTION

The aim was to investigate psychiatric health care utilization two years before death by suicide among individuals with previous suicide attempts (PSA) compared with those without (NSA).

METHOD

A retrospective population-based cohort study was conducted including 484 individuals who died by suicide in Sweden in 2015 and were in contact with psychiatric services within the two years preceding death, identified through the Cause of Death register. Data on psychiatric health care two years before death, including suicide attempts according to notes in the medical record was used. Associations between having at least one PSA vs. NSA and health care utilization were estimated as odds ratios (OR) with 95% confidence intervals (CI) by logistic regression analyses.

RESULTS

Of the 484 individuals included, 51% had PSA. Those with PSA were more likely than NSA to have received a psychiatric diagnosis [OR 1.96 (CI 95% 1.17-3.30)], to have ongoing psychotropic medication [OR 1.96 (CI 95% 1.15-3.36)] and to have been absent from appointments during the last three months [1.97 (1.25-3.13)]. In addition, elevated suicide risk was more often noted in the psychiatric case records of those with a PSA than those without [OR 2.17 (CI 95% 1.24-3.79)].

CONCLUSION

The results underline the importance of improved suicide risk assessment as well as thorough diagnostic assessment and when indicated, psychiatric treatment as suicide preventive interventions regardless of PSA. Furthermore, the larger proportion of absence from appointments in individuals with PSA may indicate a need of improved alliance between psychiatric care providers and individuals with PSA.HIGHLIGHTSBeing assessed with elevated suicide risk was more common among those with previous attempt/s (PSA).One-fifth of all with no previous attempt (NSA) had no psychiatric diagnosis, compared to one in ten in those with PSA.Receiving psychotropic medication was more common among those with PSA.

Suicide and suicide attempts in the Pacific Islands: A Systematic Literature Review

Background

The Pacific Islands have some of the highest rates of suicide in the Western Pacific region. The purpose of this study was to systematically review the literature on suicidal behaviour in the Pacific Islands.

Methods

A comprehensive search of Web of Science, PubMed, PsycINFO, Cochrane, CINAHL and Embase databases was conducted for all articles published until 1^st February 2021. Inclusion criteria included papers that referred to a pre-specified list of Pacific Islands. Papers referring exclusively to other countries were excluded. Other exclusion criteria included not being about suicide or suicide attempts or not presenting original research. Narrative synthesis was applied without meta-analysis. The review followed PRISMA guidelines.

Findings

A total of 36 papers were included for review. Of the Pacific Islands, Kiribati has the highest age-standardised rate of suicide mortality. Key risk groups across the Islands included youth, people of Indian ethnicity in Fiji (a prominent ethnic group in Fiji), and Indigenous peoples across other Islands. Prominent methods were self-poisoning and hanging. A distinct lack of intervention studies was found.

Interpretation

Overall, the Pacific Islands appear to have relatively high rates of suicide and suicide attempts compared to other countries in the region. This was particularly striking among youth. This review provides important directions for future suicide prevention activities, including means restriction, sensitive media/community coverage, enhanced surveillance, and the development and evaluation of interventions tailored to the needs of young people and other cultural groups.

Funding

Psychiatric and physical rehabilitation intensive approach for suicide attempters by jumping from heights

Suicide is an important public health problem and one of the leading causes of death worldwide. Suicide behavior is influenced by interacting biological, psychological, environmental and current situational factors. One of the most important components modulating the risk of suicide as well his prevention is mental health: it is estimated that up to 90% of individuals who attempt suicide meets the criteria for a psychiatric disorder. Multiple other factors, such as physical illness, can be related to suicidal behaviors. Medical disorders may themselves be associated with an increased risk of suicide or be consequence of violent suicide attempts such as jumping from height. Providing optimal treatment for patients with suicidal behaviors, especially if violent, involves multiple treatments that may include psychiatric, psychological and physical therapies. Using a case series approach, we describe an acute psychiatric treatment program combined with intensive rehabilitation therapy in patients hospitalized for violent suicide attempts caused by jumping from height. The patients were treated through a multidisciplinary, simultaneous and integrated care program made up of a team of psychiatrists and physiatrists who work dynamically together with a flexible approach based on the specific clinical characteristics of each patient.

Suicide attempts among adults denying active suicidal ideation: An examination of the relationship between suicidal thought content and suicidal behavior

OBJECTIVES

The purpose of the current study was to examine the possibility that there are multiple pathways to suicidal behavior by conducting a fine-grained investigation of the relationship between suicidal thought content and suicidal behavior.

METHODS

Six thousand two hundred US adults completed self-report measures of suicidal thoughts and behaviors. Descriptive statistics and logistic regression were used to examine the relationship between suicidal thoughts and behaviors.

RESULTS

About 36.0% of participants with a lifetime suicide attempt denied ever experiencing any active suicidal thoughts and 11.0% denied ever experiencing any suicidal thoughts; 53.8% of recent attempters denied recent active suicidal thoughts and 22.6% denied any recent suicidal thoughts. Additionally, the sole presence of passive suicidal ideation was associated with increased odds of lifetime and past-month suicide attempts.

CONCLUSIONS

These findings suggest that there are likely multiple pathways to suicide, some of which do not involve progressively worsening suicidal thoughts.

"Lock and Protect": Development of a Digital Decision Aid to Support Lethal Means Counseling in Parents of Suicidal Youth

Objective: Reducing access to lethal methods is an effective suicide prevention strategy that is often neglected in routine care. Digital interventions have shown promise for addressing such gaps in care; and decision aids have proven useful for supporting complicated health-related decisions, like those involving lethal means restriction. This article describes a parent/caregiver-facing web-based decision aid, the development process, and user testing. Method: A user-centered, participatory, mixed methods development design was employed. Beginning with an adult-focused decision aid developed by members of our team, we assessed ten iterations of the parent/caregiver decision aid with stakeholders (N = 85) using qualitative interviews and quantitative surveys. Stakeholders included: parents/caregivers whose children had histories of suicidal episodes before age 25, young adults with histories of suicidal thoughts/behaviors, firearm owners/representatives from firearm stores/ranges/groups, mental and medical health care providers, and emergency responders. Results: The final "Lock and Protect" decision aid was viewed as "useful for changing access to lethal means" by 100% of participants. Ninety-four percent of participants rated the information on reducing access to lethal means as good to excellent, and 91% rated the information on storage options as good to excellent. Qualitative feedback underscored a preference for offering this digital tool with a "human touch," as part of safety and discharge planning. Conclusions: "Lock and Protect" is a user-friendly web-based tool with potential for improving rates of lethal means counseling for parents/caregivers of suicidal youth and ultimately reducing pre-mature deaths by suicide.

Health care disparities for incarcerated adults after a suicide attempt

OBJECTIVE

Incarcerated adults have high rates of fatal and nonfatal suicidal behaviors. Suicide prevention recommendations stress the need for the provision of health care for incarcerated adults after suicide attempts, yet prison policies and practices often focus instead on punitive responses to suicidal behaviors. Existing research is limited regarding factors that predict the provision of health care to incarcerated adults post-suicide attempt. The current study examined individual, incident, and institutional factors as predictors of health care to incarcerated adults post-suicide attempt.

METHOD

We used data from critical incidents reports for suicide attempts (N = 495) to conduct mixed-effects logistical regression models.

RESULTS

Staff responded to suicide attempts by placing incarcerated adults under direct observation (with no care) or in segregation at odds two and three times higher than of providing health care, particularly in prisons for men. Race was a significant factor; incidents involving Black men were less likely than incidents involving white men to include staff requesting health care, and incidents involving Black women were less likely than incidents involving white women to include requesting and providing health care.

CONCLUSIONS

This study's findings highlight factors predicting health care responses to suicide attempts and the need to address and prevent health care disparities in prisons.

Racial/ethnic discrimination as race-based trauma and suicide-related risk in racial/ethnic minority young adults: The explanatory roles of stress sensitivity and dissociation

Objective: Drawing on race-based trauma models, the present study examined common reactions to trauma exposure (i.e., stress sensitivity, dissociative symptoms, depressive symptoms), as potential explanatory factors in the relation between racial/ethnic discrimination and suicide-related risk among racial and ethnic minority young adults. Method: A group of racial and ethnic minority (N = 747; 61% women; 63% U.S.-born; 34% Asian American) young adults, ages 18-29 (M = 19.84; SD = 2.22), completed a battery of self-report measures online. Accounting for demographics and other trauma exposures, direct and indirect associations between racial/ethnic discrimination and suicide attempt (SA) through stress sensitivity, dissociative symptoms, depressive symptoms, and suicide ideation (SI) were examined using hierarchical linear regression models and bootstrapping methods. Results: There was a direct association between racial/ethnic discrimination and stress sensitivity, dissociative symptoms, and depressive symptoms, but not SI or SA, after accounting for demographics and trauma exposures. There was also an indirect association between racial/ethnic discrimination and SI and SA through stress sensitivity, dissociative symptoms, and depressive symptoms. Conclusion: Experiences of racial/ethnic discrimination may function as a source of traumatic stress in racial and ethnic minority young adults to confer risk for SI and SA via stress sensitivity, dissociation, and depressive symptoms. Addressing racial/ethnic discrimination may help reduce suicide-related risk by targeting stress-related exposures particularly relevant to racial and ethnic minority young adults.

Suicidality risk among adults with binge-eating disorder

OBJECTIVE

To estimate relative suicidality risk associated with binge-eating disorder (BED).

METHODS

Retrospective study of patients identified as having BED (N = 1042) and a matched general population cohort (N = 10,420) from the Optum electronic health record database between January 2009 and September 2015. Patients had ≥1 outpatient encounter with a provider who recognized BED during the 12-month baseline preceding entry date. Incidence and relative risk of suicidality were assessed.

RESULTS

Incidence per 1000 person-years (95% CI) of suicidal ideation and suicide attempts, respectively, was 31.1 (23.1, 41.0) and 12.7 (7.9, 19.4) in the BED cohort and 5.8 (4.7, 7.1) and 1.4 (0.9, 2.2) in the comparator cohort. Risk of suicidal ideation and suicide attempts was greater in the BED cohort (HR [95% CIs], 6.43 [4.42, 9.37]) than in the comparator cohort (HR [95% CI], 9.47 [4.99, 17.98]) during follow-up. After adjusting for psychiatric comorbidities, associations of suicidal ideation and suicide attempts with BED remained elevated in patients with BED having histories of suicidality.

CONCLUSIONS

Findings suggest that history of suicidality may result in an increased risk of suicidal ideation and suicide attempts in patients with BED relative to the general population. Psychiatric comorbidity burden may explain the elevated risk of these conditions in BED.

Childhood abuse experiences, depression and dissociation symptoms in relation to suicide attempts and suicidal ideation

This study aimed to examine associations between suicide attempts (SA), suicidal ideation (SI), depression, dissociative symptoms, emotional abuse, physical abuse and sexual abuse, and to explore predictors of SA and SI, as well as possible mediating factors. We also aimed to examine support for a dissociative depression subgroup. Participating in this study were 342 adults, of these were 138 respondents with a diagnosis of depression (DG), and 204 respondents comprising a community sample (CS). Respondents completed the Center for Epidemiologic Studies Depression Scale - Revised (CESD-R), Childhood Trauma Questionnaire - Short Form (CTQ-SF), and Dissociative Experience Scale (DES). All but two (DES-Absorption and DES - Depersonalization/Derealization) of the study variable mean scores were higher in the DG than in the CS group. Regression analysis showed that SA was predicted by sexual abuse and DES-Amnesia in the CS group. Structural equation modeling revealed that in both groups the types of abuse were reciprocally correlated, emotional abuse was linked to dissociation, which in turn was related to depression, which is turn was predictive of suicide ideation. Depression had a full mediating effect between dissociation and suicide ideation in the CS, and a partial mediating effect in the DG. Sexual abuse had a direct effect upon depression and suicide ideation in the DG. Cluster analysis provided support for a dissociative depression subtype.

Clarifying the Relationship of Dissociative Experiences to Suicide Ideation and Attempts: A Multimethod Examination in Two Samples

Fears of pain, injury, and death may represent key barriers to acting on suicidal thoughts. Dissociation, which involves a disconnection from one's body, may reduce fears and sensations of pain associated with harming the body, in turn facilitating suicide attempts. This study examined whether dissociation differentiated individuals with a history of suicide attempts from those with a history of suicide ideation, and investigated whether other relevant constructs explain this relationship. Sample 1 included 754 undergraduates (M_age = 21, 79% female) who completed a battery of self-report measures. Sample 2 included 247 undergraduates (M_age = 19, 74% female) who completed a self-report measure of dissociation, a clinical interview regarding suicide history, and four counterbalanced behavioral pain tolerance tasks. In both samples, dissociation was elevated in lifetime attempters compared to ideators (d = 0.28; d = 0.46; ps = 0.01) and slightly elevated in lifetime ideators compared to nonsuicidal individuals (d = 0.19, p = .02; d = 0.24, p = .47), though this effect was non-significant in the latter sample. In Sample 1, dissociation no longer differentiated attempters from ideators after controlling for clinical covariates. In Sample 2, dissociation was unrelated to behavioral pain tolerance tasks, and these tasks did not account for the association between dissociation and attempts. Overall, dissociation differentiated individuals with a history of suicide attempts from those with ideation alone in both samples. Pain tolerance did not explain this association; instead, it is possible that the relationship of dissociation to suicide attempts is due to "third variables" associated with both phenomena, such as symptoms of borderline personality disorder or posttraumatic stress disorder.

Future Well-Being Among People Who Attempt Suicide and Survive: Research Recommendations

Over 48,000 people died by suicide in 2018 in the United States, and more than 25 times that number attempted suicide. Research on suicide has focused much more on risk factors and adverse outcomes than on protective factors and more healthy functioning. Consequently, little is known regarding relatively positive long-term psychological adaptation among people who attempt suicide and survive. We recommend inquiry into the phenomenon of long-term well-being after nonfatal suicide attempts, and we explain how this inquiry complements traditional risk research by (a) providing a more comprehensive understanding of the sequelae of suicide attempts, (b) identifying protective factors for potential use in interventions and prevention, and (c) contributing to knowledge and public education that reduce the stigma associated with suicide-related behaviors.

Self-Reported Interoceptive Sensibility Does Not Moderate the Relationship Between Eating Disorder Symptoms and Suicidal Thoughts and Behaviors

Past research has demonstrated a strong relationship between eating disorders (EDs) and suicidality (i.e., suicidal thoughts, plans, and attempts), and preliminary work within the framework of the interpersonal psychological theory of suicide (Joiner, 2007) suggests that potentially painful ED behaviors (binge eating, purging, fasting, excessive exercise) may contribute to increased risk of suicide through heightened pain tolerance and increased capability of suicide. However, additional explanations are needed for why only some individuals with EDs actually engage in suicidal behaviors (i.e., attempt suicide), whereas others do not. A growing body of literature suggests that interoceptive deficits (a disconnection from one's own bodily sensations and emotions; IDs) might be a factor linking eating disorders and suicide. To better understand this relationship, the current study tests the moderating effects of self-reported IDs on the relations between ED behaviors and suicidality and past suicide attempts in a transdiagnostic ED sample (N = 181). We hypothesized that ED behaviors would directly relate to suicidality, but that IDs would moderate the relationship between ED behaviors and past suicide attempts, such that those high in IDs would demonstrate a stronger relationship between ED behaviors and suicide attempts. Contrary to our hypothesis, IDs did not moderate the relationship; instead, fasting and purging had significant and strong main effects on suicidality and past suicide attempts without moderation effects. Results suggest that fasting and purging may be important ED behaviors to consider in the relationship between EDs and suicidality. Future directions include further examining the relationship between IDs, suicidality, and EDs using measures of IDs that better encompass physical (as opposed to emotional) aspects of IDs.

Effectiveness of a Continuity-of-Care Model to Reduce Youth Suicidality

Background: Suicidal ideation and recent suicide attempts greatly increase the risk of suicide among youth. Many youth experiencing suicidality are not adequately connected to in-person treatment. Aims: This study aimed to determine the efficacy of a continuity-of-care approach in reducing suicide attempts, ideation, and related hospital and emergency department (ED) visits among youth at high risk for suicide. Method: Data on suicidal ideation, attempts, and related hospital and ED visits were collected over a 6-month period for youth under age 25 (n = 376). One-way repeated measures ANOVA and Cochran's Q tests assessed change from intake at the 3- and 6-month follow-up. Results: Youth had significantly fewer suicide attempts and related hospital and ED visits at both 3- and 6-month timepoints. Suicidal ideation decreased to 52% from intake to 6-month follow-up. Limitations: This study lacked a comparison population to examine continuity-of-care versus treatment-as-usual. Furthermore, the study did not extend beyond 6 months, limiting the ability to assess the intervention's long-term effectiveness. Conclusion: This youth-focused continuity-of-care model reduced suicidal ideation and related behaviors. Further studies should utilize control groups to confirm the validity of these results.

Rethinking Suicide Risk With a New Generation of Suicide Theories

BACKGROUND

Suicide is a global concern to nurses and other health-care providers. However, deaths by suicide are only part of the spectrum of suicide, as suicidal thinking and behaviors may precede a suicide attempt. Theoretical models are used infrequently in research to explain how the individual progresses from suicidal ideation to a suicide attempt. Thus, there is a critical need to advance the study of suicide with useful theoretical models to describe and explain processes whereby suicidal thoughts transition to attempts and to suicide.

PURPOSE

This article provides a conceptual discussion and scoping review comparing historical and contemporary ideation-to-action theories of suicide.

METHOD

Systematic reviews and meta-analyses from three databases (CINAHL, JSTOR, and PsychINFO) were reviewed to find literature describing suicide theories.

RESULTS

Historically, theory applications have limited capacity to differentiate between those individuals with suicidal ideations and those who attempt suicide. Newer theories, grounded in the ideation-to-action framework, propose distinct processes explaining what moves an individual from suicidal ideations toward suicidal behaviors.

IMPLICATIONS FOR PRACTICE

The ideation-to-action theories can guide health-care providers' assessment of at-risk individuals beyond merely asking about suicidal thinking.

CONCLUSION

The new generation of suicide theories suggest that suicidal ideations are only one component of risk. The common factor in ideation-to-action theories that distinguishes ideators from attempters is the acquired capability for suicide.

Estimating the marginal effect of a continuous exposure on an ordinal outcome using data subject to covariate-driven treatment and visit processes

In the statistical literature, a number of methods have been proposed to ensure valid inference about marginal effects of variables on a longitudinal outcome in settings with irregular monitoring times. However, the potential biases due to covariate-driven monitoring times and confounding have rarely been considered simultaneously, and never in a setting with an ordinal outcome and a continuous exposure. In this work, we propose and demonstrate a methodology for causal inference in such a setting, relying on a proportional odds model to study the effect of the exposure on the outcome. Irregular observation times are considered via a proportional rate model, and a generalization of inverse probability of treatment weights is used to account for the continuous exposure. We motivate our methodology by the estimation of the marginal (causal) effect of the time spent on video or computer games on suicide attempts in the Add Health study, a longitudinal study in the United States. Although in the Add Health data, observation times are prespecified, our proposed approach is applicable even in more general settings such as when analyzing data from electronic health records where observations are highly irregular. In simulation studies, we let observation times vary across individuals and demonstrate that not accounting for biasing imbalances due to the monitoring and the exposure schemes can bias the estimate for the marginal odds ratio of exposure.
