Prevalence of and risk factors for suicide attempts versus suicide gestures: Analysis of the National Comorbidity Survey

The impact of childhood emotional abuse on the developmental trajectory of non-suicidal self-injury in adolescents: The mediating role of self-compassion and peer attachment

BACKGROUND

Non-suicidal self-injury (NSSI) is a concerning health problem that afflicts some adolescents, and childhood emotional abuse is an early risk factor for NSSI. However, few studies have focused on identifying specific mediators underlying the relationship between childhood emotional abuse and the developmental trajectory of NSSI. Self-compassion and peer attachment are important intrapersonal and interpersonal factors influencing NSSI. However, it remains unclear whether self-compassion and peer attachment may mediate the relationship between childhood emotional abuse and the developmental trajectory of NSSI.

OBJECTIVE

Based on Nock's integrated theoretical model and the Four-Function Model of self-injury, this study investigates the developmental change of NSSI during one year in adolescence and the mediating roles of self-compassion (as an intrapersonal factor) and peer attachment (as an interpersonal factor) in childhood emotional abuse and the initial level and rate of change of NSSI.

PARTICIPANTS AND METHODS

A total of 1214 Chinese adolescents (M = 15.46, SD = 0.71; 737 boys and 477 girls) were recruited to measure NSSI, childhood emotional abuse, self-compassion, and peer attachment at T1 and then NSSI was assessed again at T2 and T3 within the same calendar year. A latent growth model was used to explore the developmental change of NSSI; structural equation modeling was constructed to explore the mediating role of self-compassion and peer attachment.

RESULTS

The results showed that the frequency of NSSI occurred at a very low level among Chinese adolescents and decreased significantly over the year. Childhood emotional abuse positively predicted the initial level of NSSI and negatively predicted the rate of decline in NSSI. In addition, self-compassion and peer attachment partially mediate between childhood emotional abuse and the initial levels and rate of change in adolescent NSSI.

CONCLUSIONS

The findings suggested a downward trend in adolescent NSSI development over the one-year follow-up, and indicated that childhood emotional abuse is related to the development of NSSI. Additionally, the study suggested that increasing self-compassion and improving peer relationships offer opportunities for prevention and intervention for NSSI in adolescence.

Psychometric Properties of Korean Version of Nonsuicidal Self-injury Inventory: Validation Study of Deliberate Self-harm Inventory

Objective

This study aimed to develop a Korean version of the Nonsuicidal Self-injury Inventory (K-NSSI) through the Deliberate Self-harm Inventory (DSHI) developed by Gratz for the Korean context and confirm its reliability and validity for clinical application.

Methods

A total of 188 participants were analyzed utilizing the DSHI, the Korean version of the Self-harm Inventory, the Personality Assessment Inventory-Borderline Features (PAI-BOR), and the DSM-5 Level-2-Depression scale (Level-2-Dep). Cronbach's α assessed their reliability, while frequency analysis examined the items of the K-NSSI scales. Validity of the K-NSSI was confirmed through correlation analyses between K-NSSI (tendency for and frequency of nonsuicidal self-injury [NSSI] behavior) and SHI, PAI-BOR total scale, four subscales of PAI-BOR, and Level-2-Dep scale. Polyserial correlations analyzed the correlation between the presence of NSSI behavior and other scales. Confirmatory factor analysis and structural equation modeling explored the relationship between borderline personality features and self-harm.

Results

Cronbach's α was 0.71, indicating an "acceptable" level of reliability. Statistically significant correlations were observed between the presence of NSSI behavior and the total scores of SHI and PAI-BOR, and the four subscales of PAI-BOR. The frequency of NSSI showed statistically significant correlations with the total score of SHI and PAI-BOR, and its four subscales. Notably, 13.8% of participants reported engaging in self-harm behaviors, 26.9% reported a single occurrence, and 73.1% reported two or more instances. Structural equation modeling demonstrated that self-harm adequately predicted borderline personality traits.

Conclusion

This study successfully validated the adaptation of DSHI into K-NSSI. The K-NSSI can facilitate interventions for self-harm incidents.

Psychotic Experiences and Risk of Suicidal Thoughts and Behaviors: A Systematic Review and Meta-Analysis of Longitudinal Population Studies

BACKGROUND AND HYPOTHESIS

Since a prior systematic review and meta-analysis reported an association between psychotic experiences (PEs) and suicidal thoughts and behaviors, a large number of new studies have been published on the topic, including several novel studies on the association between PEs and transition from suicidal ideation to attempt.

STUDY DESIGN

Two authors independently searched PubMed, Embase, CINAHL, and PsycINFO databases from inception until July 2023, conducted data extraction, and assessed study quality using the Newcastle-Ottawa Quality Assessment Scale. Random-effects models were used to calculate pooled odds ratios (ORs) for the association of PEs and subsequent suicide ideation, suicide attempts, suicide death, and transition from suicidal ideation to attempt, first for the total population, and second stratified by age group. Secondary analyses assessed the mediating role of co-occurring psychopathology.

STUDY RESULTS

Twenty studies from 18 different samples (n = 81,861) were identified. Individuals who reported PEs had increased odds of subsequent suicidal ideation (k = 12, OR = 1.90, 95% CI = 1.65-2.19), suicide attempt (k = 13, OR = 2.95, 95% CI = 2.21-3.94), transition from suicidal ideation to suicide attempt (k = 3, OR = 2.83, 95% CI = 1.60-4.99), and suicide death (k = 1, OR = 4.39, 95% CI = 1.63-11.80). This heightened risk was stable across childhood, adolescence, and adulthood. PEs predicted suicide attempts over and above co-occurring psychopathology (k = 8, OR = 2.85, 95% CI = 2.06-3.95).

CONCLUSIONS

Individuals reporting PEs are at increased risk of all types of suicidal thoughts and behaviors. In addition, PEs are particularly important risk markers for future suicidal behaviors, including in individuals already reporting suicidal ideation. This risk is in excess of what is explained by co-occurring psychopathology.

Self-injury and suicidal behaviors in high-risk adolescents: Distal predictors, proximal correlates, and interactive effects of impulsivity and emotion dysregulation

Suicide rates are rising among U.S. youth, yet our understanding of developmental mechanisms associated with increased suicide risk is limited. One high-risk pathway involves an interaction between heritable trait impulsivity and emotion dysregulation (ED). Together, these confer increased vulnerability to nonsuicidal self-injury (NSSI), suicide ideation (SI), and suicide attempts (SAs). Previous work, however, has been limited to homogeneous samples. We extend the Impulsivity × ED hypothesis to a more diverse sample of adolescents (N = 344, ages 12-15 at Baseline, 107 males and 237 females) who were treated for major depression and assessed four times over two years. In multilevel models, the impulsivity × ED interaction was associated with higher levels and worse trajectories of NSSI, SI, and SAs. As expected, stressful life events were also associated with poorer trajectories for all outcomes, and NSSI was associated with future and concurrent SI and SAs. These findings extend one developmental pathway of risk for self-harming and suicidal behaviors to more diverse adolescents, with potential implications for prevention.

Global patterns and trends of suicide mortality and years of life lost among adolescents and young adults from 1990 to 2021: a systematic analysis for the Global Burden of Disease Study 2021

AIMS

We aimed to report an overview of trends in suicide mortality and years of life lost (YLLs) among adolescents and young adults aged 10-24 years by sex, age group, Socio-demographic Index (SDI), region and country from 1990 to 2021 as well as the suicide mortality with age, period and birth cohort effects.

METHODS

Estimates and 95% uncertainty intervals for suicide mortality and YLLs were extracted from the Global Burden of Diseases Study 2021. Joinpoint analysis was used to calculate the annual percentage change (APC) and average annual percentage change (AAPC) to describe the mortality and rate of YLLs trends. Age, period and cohort model was utilized to disentangle age, period and birth cohort effects on suicide mortality trends.

RESULTS

Globally, suicide mortality and the rate of YLLs among adolescents and young adults both declined from 1990 to 2021 (AAPC: -1.6 [-2.1 to -1.2]). In 2021, the global number of suicide death cases was 112.9 thousand [103.9-122.2 thousand] and led to 7.9 million [7.2-8.6 million] YLLs. A significant reduction in suicide mortality was observed in all sexes and age groups. By SDI quintiles, the high SDI region (AAPC: -0.3 [-0.6 to 0.0]) had the slowest decline trend, and low-middle SDI region remained the highest suicide mortality till 2021 (7.8 per 100,000 population [6.9-8.6]). Most SDI regions showed generally lower period and cohort effects during the study period, whereas high SDI region showed more unfavourable risks, especially period and cohort effects in females. Regionally, Central Latin America (AAPC: 1.7 [1.1-2.3]), Tropical Latin America (AAPC: 1.5 [0.9-2.0]), High-income Asia Pacific (AAPC: 1.2 [0.7-1.7]) and Southern sub-Saharan Africa (AAPC: 0.8 [0.4-1.2]) had the significance increase in suicide mortality. In 2021, Southern sub-Saharan Africa had the highest mortality (10.5 per 100,000 population [8.6-12.5]). Nationally, a total of 29 countries had a significant upward trend in suicide mortality and rate of YLLs over the past three decades, and certain countries in low-middle and middle regions exhibited an extremely higher burden of suicide.

CONCLUSIONS

Global suicide mortality and the rate of YLLs among adolescents and young adults both declined from 1990 to 2021, but obvious variability was observed across regions and countries. Earlier mental health education and targeted management are urgently required for adolescents and young adults in certain areas.

Pre-suicidal attempt: An intermediate type within ideation-to-action framework

INTRODUCTION

Understanding the mechanisms of suicidal behavior is a prerequisite for suicide prevention and intervention. The current study aims to propose and verify the utility of pre-suicidal attempt as an intermediate type in the transition from suicidal ideation to suicidal attempt within the ideation-to-action framework.

METHODS

A sample of 1084 college students completed a measurement package consisting of suicide history, suicide risk factors, and demographic information. Stratified stepwise multiple regression models and mediated moderation models were used to examine the relationship among the variables.

RESULTS

Pre-suicidal attempts rather than suicidal ideation are predictive of suicide attempts. Age, depression, thwarted belongingness, fearlessness about death, perceived burdensomeness and suicidal ideation were predictors of pre-suicidal attempts. Supporting the interpersonal theory of suicide, pre-suicidal attempts mediated the relationship between suicidal ideation and suicidal attempts and were positively moderated by pain tolerance and fearlessness about death. The pre-suicidal attempters scored higher on fearlessness about death and suicide risk than the ideators, while pre-suicidal attempters scored significantly lower on suicide risk than suicide attempters.

CONCLUSION

As an independent intermediate type within the ideation-to-action framework, pre-suicidal attempts contribute to deepen the understanding of the intermediate transition from suicidal ideation to suicidal attempts.

Gender Identity in Forensic Death Investigation: A Narrative Review and Suggested Guidelines for Documenting and Reporting

ABSTRACT

In the current body of forensic literature, there is little guidance available regarding death investigations of transgender, intersex, and gender diverse individuals. An increase in the prevalence of gender diverse identifying people and the frequency in which these individuals experience a premature death makes it more likely these deaths will fall under the jurisdiction of the medical examiner's office. The inability to navigate these diverse cases due to a lack of training, education, and support may leave forensic professionals without the tools needed to accurately represent these deaths.This narrative review is intended to provide the foundational knowledge needed by forensic death investigators when investigating gender identity in death, including suggested guidelines for a more effective and empathetic death investigation. A better understanding of the implications and applications of this information when included in reports will bolster the quality and quantity of the data reported and collected. This will lead to more accurate monitoring and reporting of violent, suicidal, and homicidal deaths of transgender, intersex, and other gender diverse individuals, and a higher identification rate of unidentified remains with gender diverse markers.

Nonsuicidal self-injury as the gateway and consequence of suicidal ideation among adolescents: a cross-lagged regression analysis

Background

There is a consensus that both nonsuicidal self-injury (NSSI) and suicidal ideation as risk factors for suicidal behavior have a strong connection. However, a lack of longitudinal information has limited the clarification of the concrete relationship between them.

Aims

This study aimed to examine the specific mechanism between NSSI and suicidal ideation over time, during adolescence.

Method

A longitudinal study was conducted with 193 Chinese adolescents. NSSI and suicidal ideations were examined over the course of a 1year followed-up, and three waves of data were collected.

Results

The NSSI at time T1 significantly positively predicted suicidal ideation at time T2; Suicidal ideation at time T2 also significantly positively predicted NSSI at time T3.

Limitations

Given that the small number of participants with suicidal ideation and NSSI, the findings of the study should be interpreted with caution and a lager sample is needed in the future.

Conclusion

It was suggested that NSSI may occur before suicidal ideation, which in turn would strengthen NSSI, so interventions should be carried out from two aspects (behaviors and thoughts) to improve adolescents' mental health.

The Interpersonal Psychological Theory of Suicide in Italian University Students: Validation of the INQ-15 and the ACSS-FAD

In the frame of the interpersonal psychological theory of suicide (IPTS), Interpersonal Needs Questionnaire (INQ-15) assesses thwarted belongingness (TB) and perceived burdensomeness (PB), related to suicidal ideation (SI); Acquired Capability for Suicide Scale-Fearlessness About Death (ACSS-FAD) measures this component which contributes to lethal self-harm. The objective was to evaluate the psychometric properties of INQ-15 and ACSS-FAD in a population of Italian university students. Since the Italian INQ-15 was already validated, we translated ACSS-FAD through a multistage procedure and administered both to 1,665 Italian university students. Factor analysis confirmed a two-factor-related model of INQ-15, one factor of ACSS-FAD, and good reliability for both. We proved the association between INQ-15 and current SI and between ACSS-FAD and lifetime suicidal planning and/or suicide attempt. The convergent and discriminant validities were in line with those of previous studies. Both tools are valid and reliable to assess the constructs associated with suicide outcomes according to IPTS.

Suicide Attempts and Ideation Among Veterans/Service Members and Non-Veterans Over 5 Years Following Traumatic Brain Injury: A Combined NIDILRR and VA TBI Model Systems Study

OBJECTIVE

This study compared rates of suicide attempt (SA) and suicidal ideation (SI) during the first 5 years after traumatic brain injury (TBI) among veterans and service members (V/SMs) in the Veterans Affairs (VA) and the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) Model Systems National Databases to each other and to non-veterans (non-Vs) in the NIDILRR database.

SETTING

Twenty-one NIDILRR and 5 VA TBI Model Systems (TBIMS) inpatient rehabilitation facilities in the United States.

PARTICIPANTS

Participants with TBI were discharged from rehabilitation alive, had a known military status recorded (either non-V or history of military service), and successful 1-, 2-, and/or 5-year follow-up interviews completed between 2009 and 2021. The year 1 cohort included 8737 unique participants (8347 with SA data and 3987 with SI data); the year 2 (7628 participants) and year 5 (4837 participants) cohorts both had similar demographic characteristics to the year 1 cohort.

DESIGN

Longitudinal design with data collected across TBIMS centers at 1, 2, and 5 years post-injury.

MAIN OUTCOMES AND MEASURES

History of SA in past year and SI in past 2 weeks assessed by the Patient Health Questionnaire-9 (PHQ-9). Patient demographics, injury characteristics, and rehabilitation outcomes were also assessed.

RESULTS

Full sample rates of SA were 1.9%, 1.5%, and 1.6%, and rates of SI were 9.6%, 10.1%, and 8.7% (respectively at years 1, 2, and 5). There were significant differences among groups based on demographic, injury-related, mental/behavioral health, and functional outcome variables. Characteristics predicting SA/SI related to mental health history, substance use, younger age, lower functional independence, and greater levels of disability.

CONCLUSIONS

Compared with participants with TBI in the NIDILRR system, higher rates of SI among V/SMs with TBI in the VA system appear associated with risk factors observed within this group, including mental/behavioral health characteristics and overall levels of disability.

Lower levels of social support are associated with risk for future suicide attempts in a clinical sample of transgender and gender diverse adults

PURPOSE

Transgender and gender diverse (TGD) adults are disproportionately affected by suicide. Social support and connection to the broader TGD community may help lower TGD adults' odds of having a suicide attempt (SA). The current study examined whether baseline levels of social support and community connectedness were associated with TGD adult's prospective odds of having a SA over 12 months of follow-up.

METHODS

Longitudinal data for the current study came from a patient cohort of TGD adults enrolled in the LEGACY Project. Descriptive statistics and an attrition analysis were used to examine characteristics of the cohort and missingness over time. Logistic generalized estimating equation models were used to examine factors associated with patients' odds of having a past 6-month SA at 6- or 12-month follow-up.

RESULTS

During the 12-month follow-up period, a total of 26 patients (3.1%; N = 830) reported having a SA. The 6-month incidence of SAs was approximately 2% at both 6- and 12-months of follow-up (6 months: N = 830; 12 months: N = 495). Baseline factors associated with increased odds of a future SA included gender identity (transfeminine vs. transmasculine: adjusted odds ratio [aOR] = 3.73, 95% confidence interval [CI] = 1.26-11.08; nonbinary vs. transmasculine: aOR = 3.09, 95% CI = 1.03-9.21), having a prior SA (aOR = 6.44, 95% CI = 2.63-15.79), and having moderate vs. high perceived social support (aOR = 4.25, 95% CI = 1.65-10.90).

CONCLUSION

Lower levels of social support are associated with risk for future suicide attempts among TGD adults. Findings may inform screening practices for future suicide risk and the development of interventions to improve mental health outcomes for TGD adults.

Suicidal Behaviors and Associated Factors Among Adult Psychiatric Patients Attending Psychiatric Clinic at Public Hospitals in Ethiopia: A Cross-Sectional Study

Suicidal behaviors in persons with mental illnesses are the most prevalent psychiatric crises, requiring scholars and mental health task teams to prioritize public health concerns. However, there is a scarcity of data in Ethiopia, particularly for patients with mental illness. As a result, the goal of this study was to assess the prevalence of suicidal behaviors and associated factors among individuals with mental illness visiting public hospital psychiatric clinic units in eastern Ethiopia. A facility-based cross-sectional study was conducted from October 15 to November 15, 2022, with 411 individuals with mental illness visiting psychiatric clinic units at public hospitals in eastern Ethiopia. To select participants in the study, a systematic random sampling method was used. A structured face-to-face interview was used to gather data. The Suicidal Behavior Questionnaire-Revised (SBQ-R) was used to measure suicidal behaviors. Epidata 3.1 version was used to enter the data, and SPSS version 24 was used to analyze it. Both bivariable and multivariable logistic regression analyses were employed. In the final model, variables with p-values less than 0.05 were considered statistically significant. To identify variables associated with suicidal behavior, the adjusted odds ratio (AOR) and 95% confidence interval (CI) were utilized. Out of a total of 411 eligible participants, 402 involved in this study, giving a response rate of 97.8%. The prevalence of suicidal behavior was 46.3%, (95% CI: 41-50.7). Depression (AOR = 2.21,95% CI: 1.04, 4.69), medication non-adherence (AOR = 1.95, 95% CI: 1.19, 3.18), bipolar disorders (AOR = 1.79, 95% CI: 1.55, 3.53), and current alcohol use (AOR = 1.81, 95% CI: 1.01, 3.28) were variables associated with suicidal behaviors. This study found a high rate of suicidal behaviors among adult individuals with mental illness in public hospitals in eastern Ethiopia. Suicidal behavior was highly associated with depression, bipolar disorders, current alcohol use, and medication non-adherence. Psychiatric professionals should assess patient suicidal risk assessment routinely and should put the diagnosis with suicidal if the client is suicidal so that every professional focuses on treatment besides the medication. Special attention is required for individuals who present associated features, such as history of medication non adherence, depression, and overall bipolar disorders.

Characterization of Psychiatric Inpatients: The Role of Gender Differences in Clinical and Pharmacological Patterns

BACKGROUND

Severe mental disorders that require hospitalization are disabling conditions that contribute to the burden of mental diseases. They pose increased clinical challenges and highlight the need to thoroughly explore variables emerging from daily clinical practice. In this study, we assessed to what extent gender differences may characterize a large population of psychiatric inpatients.

METHODS

We conducted a cross-sectional study in 2 Italian teaching medical centers, which included 2358 patients who were consecutively admitted to the psychiatric emergency units. We explored and characterized gender differences for variables such as prevalence of psychiatric diagnosis, presence of suicidal ideation, suicide attempts, age at onset of psychiatric illness, presence of substance or alcohol abuse, length of stay, number of hospitalizations, presence of involuntary admission, type of discharge from the hospital, and pharmacological treatment at discharge.

RESULTS

Female patients were primarily diagnosed with bipolar disorder or personality disorders. Female patients had a significantly higher prevalence of lifetime suicide attempts (23.1% vs. 16.5%, P<0.001) and a longer length of hospitalization (11.43±10.73 d vs. 10.52±10.37 d, t=-2.099, gl=2356, P=0.036) compared with male patients. Male patients had more involuntary admissions (25.1% vs. 19.7%, χ2=9.616, gl=1, P=0.002), more use of illicit substances (34.1% vs. 20.9%, χ2=51.084, gl=1, P<0.001), and higher rates of alcohol abuse (21.3% vs. 14.7%, χ2=17.182, gl=1, P<0.001) compared with female patients. Finally, antidepressants and lithium were prescribed more frequently to the female patients, whereas other mood stabilizers were more often prescribed to the male patients.

CONCLUSIONS

Our real-world results highlighted gender differences among patients with severe mental disorders admitted to psychiatric units, and suggest further investigations that may help in understanding trajectories accompanying disabling clinical conditions.

[Adolescents' Experiences of Non-Suicidal Self-Injury: An Interpretative Phenomenological Analysis Stud]

PURPOSE

This qualitative study used interpretative phenomenological analysis and photovoice methods to explore the meaning of non-suicidal self-injury experienced by adolescents.

METHODS

Participants were adolescents enrolled in middle and high schools in Gyeonggi-do and Jeollabuk-do who were selected through snowball sampling. Six participants had repeatedly engaged in self-injurious behavior for over a year. Data were collected through in-depth interviews and the photovoice method between November 2020 and July 2021. The collected data were analyzed using six steps of interpretative phenomenological analysis.

RESULTS

The results yielded 5 main themes and 18 subthemes. The main themes were 'a silent cry to an indifferent world', 'a heartache that one endures with scars', 'an inescapable cycle', 'filling the space in one's heart', and 'healing the wounds'. The study findings revealed that the self-injurious behavior of adolescents began as a consequence of feeling lost and struggling with conflicts at home and school, which helped them relieve tension and pain. Nonetheless, inflicting self-injury only left signs of regret and remorse, which became a trace that the participants wanted to hide. However, the wounds healed after receiving attention and support from others. They were determined to stop engaging in repeated self-injurious behaviors and made efforts to do so.

CONCLUSION

This study can be used as a basis for the development of educational programs to prevent non-suicidal self-injury in adolescents. Additionally, it can inform nursing interventions that focus on building support systems to help adolescents who attempt self-injury.

Systematic analysis of nonfatal suicide attempts and further diagnostic of secondary injury in strangulation survivors: A retrospective cross-sectional study

Background and Aims

Data on nonfatal suicide attempts in Germany are sparse. The study aimed to analyze data on nonfatal suicide attempts and consecutive diagnostic steps to identify secondary injuries after strangulation.

Methods

All admissions after nonfatal suicide attempt in a large Bavarian psychiatric hospital between 2014 and 2018 were reviewed and the methods were analyzed.

Results

A total of 2125 verified cases out of 2801 registered cases of nonfatal suicide attempts were included in further analysis. The most common methods were intoxication (n = 1101, 51.8%), cutting (n = 461, 21.7%), and strangulation (n = 183, 8.6%). Among survivors of strangulation with external neck compression (n = 99, 54.1%), no diagnostic steps were performed in 36 (36.4%) patients and insufficient imaging in 13 (20.6%) patients. Carotid artery dissection was detected in two (4.0%) of 50 patients with adequate neuroimaging.

Conclusions

This study provides details on nonfatal suicide attempts in Germany. Slightly more than half of the patients with strangulation underwent adequate diagnostic work-up, with 4.0% being diagnosed with dissection. Further studies with systematic screening for dissection after strangulation in psychiatric hospitals are recommended to reduce possible under-reporting.

Psychiatric Treatment and Repeat Suicide Attempts Among Adults With Substance Use, by HIV Status, United States, 2014-2020

OBJECTIVES

The association among psychiatric treatment history, HIV, and suicide reattempts among people starting treatment for substance use is not well understood. The objective of this study was to describe, by HIV status, the risk and protective factors associated with suicide reattempts among adults seeking treatment for substance use.

METHODS

The study included 340 390 US adult residents aged ≥18 years in the Addiction Severity Index-Multimedia Version network from January 1, 2014, through December 31, 2020. We used adjusted logistic regression models to estimate strength of association between prior psychiatric treatment, HIV status, and sociodemographic factors and suicide reattempts within 30 days of treatment evaluation.

RESULTS

Adults who had been prescribed psychiatric medication were less likely to have a recent suicide reattempt (adjusted odds ratio [aOR] = 0.8; 95% CI, 0.7-0.8) than adults with no prescription history. Adjusted models found similar protective effects between psychiatric treatment and suicide reattempts among adults reporting abuse, mental illness, injection drug use, and limited activity because of a medical condition. Conversely, the following were associated with recent suicide reattempts: being male (aOR = 1.4; 95% CI, 1.3-1.5), having a high school education/GED (General Educational Development) or less (aOR = 1.2; 95% CI, 1.1-1.2), being single (aOR = 1.2; 95% CI, 1.1-1.3), experiencing a pain problem (aOR = 1.2; 95% CI, 1.2-1.3), and not being referred to substance use treatment by court (aOR = 3.4; 95% CI, 3.2-3.7).

CONCLUSIONS

A history of prescribed psychiatric medication is significantly associated with a reduced risk for suicide reattempts among adults seeking substance use treatment. Clinicians should consider incorporating mental health and suicide assessments into substance use treatment plans.

Impact of Parental Mental Health and Help-Seeking on Adolescents' Suicidal Ideations and Help-Seeking Behaviors

This study aimed to evaluate the impact of parental mental health on adolescent offspring. Data regarding 6512 families from the 2010-2021 Korean National Health and Nutrition Examination Survey were analyzed; among them, 428 were placed in the suicidal ideation (SI) group and 421 were placed in the matched control (MC) group. This number was selected for the use of the propensity score matching method. The findings highlighted significant associations between parental mental health and adolescent suicidal ideation, with mothers in the SI group having higher odds of Diagnosed Depression (OR 2.109, 1.023-4.350 95% CI), Depressive Mood (OR 2.155, 1.224-3.793 95% CI), and Suicidal Ideation (OR 2.532, 1.322-4.851 95% CI) compared to the MC group. Regarding the fathers, paternal Suicidal Ideation (OR 4.295, 1.747-10.599 95% CI) was the only significant factor for adolescent suicidal ideation. In contrast, maternal depressive symptoms and help-seeking behavior significantly impacted adolescent help-seeking; Maternal Depressive Mood increased with adolescent Help-Seeking (OR 4.486, 1.312-15.340 95% CI) while Maternal Suicidal Ideation reduced the probability of Help-Seeking in the SI group (OR 0.15, 0.031-0.721, 95% CI). Chronic and severe depressive symptoms in mothers could make adolescents less likely to seek help for their suicidal ideations. Therefore, clinicians working with adolescents should prioritize a family-oriented approach.

An observational study on deliberate self-harm in individuals with alcohol dependence syndrome

Context

Comorbidities in alcohol dependence syndrome (ADS) are often associated with poor treatment outcomes and high service utilization. Deliberate self-harm (DSH) in India is a silent epidemic. There is a shortage of research on individuals with ADS, psychiatric comorbidities, and DSH.

Aim

To study DSH and psychiatric comorbidity in persons with ADS.

Settings and Design

A cross-sectional study of 1-year duration is conducted in out patient department/indoor patient department of a tertiary care hospital.

Methods and Material

Eighty-one individuals with ADS were selected purposefully. A semi-structured pro forma, the severity of alcohol dependence questionnaire, Mini-International Neuropsychiatric Interview (MINI), and Deliberate Self-Harm Inventory were administered for assessment. The statistical analysis used is as follows: correlation statistics and logistic regression.

Results

Most subjects were married, belonged to upper-middle socioeconomic status, had at least secondary education, and had moderate alcohol dependence severity. Almost 3/4th of the subjects had at least one lifetime psychiatric disorder. A past episode of major depressive disorder was found in 47%. Nearly 20% of study subjects had a history of DSH, which was significantly associated with unmarried status, and earlier age of alcohol dependence. Marital status, educational level, and age of onset of alcohol dependence explain 64.3% of the variance in DSH attempts. Suicidality was significantly related to the presence of DSH.

Conclusions

The study found a high prevalence of psychiatric disorders and a history of DSH in individuals with ADS. The study confirmed the association between DSH and suicidality and indicated a specific subpopulation of ADS who need thorough clinical assessments to recognize these psychiatric comorbidities and DSH.

The role of parents' and friends' support in preventing suicide attempts among French sexual minority adolescents

OBJECTIVES

French sexual minority adolescents are at higher risk for suicide attempts than their heterosexual peers. However, little is known about the role of parents' and friends' support among French lesbian, gay and bisexual (LGB) youth. This study aimed to research the role of their support in preventing suicide attempts among LGB adolescents in France.

MATERIALS AND METHODS

Data were drawn from a French cross-sectional study entitled "Portraits d'adolescents". Parental support was defined by satisfactory relations between participants and their parents. Friends' support was defined by satisfactory relations between participants and their friends. Chi-square and multiple logistic regression analyses were used to estimate and identify associated factors of suicide attempts in LGB as opposed to heterosexual youth.

RESULTS

Data from a sample of 14,265 French adolescents aged 13 to 20 were analyzed. Among them, 637 (4.47%) identified as LGB. Attempted suicide was independently associated with sexual orientation (30.7% vs 10.6%; OR = 2.59 [2.11-3.18]; p < 0.0001). Both parents' and friends' support appeared to be protective factors in suicide attempts among heterosexuals (adjusted ORs = 0.40 [0.35-0.46] and 0.61 [0.51-0.75], respectively), whereas in the LGB group, only parental support was significant (adjusted OR = 0.42 [0.27-0.65]), independently of other variables.

DISCUSSION

Prevention efforts might be carried out by identifying within-group differences among French adolescents with different sexual orientations. The supportive role of family members should be strengthened. Positive resources and salutary support systems may effectively prevent suicide attempts.

CONCLUSIONS

French LGB adolescents have a higher risk for suicide attempts than their heterosexual peers. Parental support was reconfirmed as a major protective factor against suicide attempts in sexual minority adolescents.

A Qualitative Examination of the Impact of Suicidal Thoughts and Behavior on Help-Seeking Among University Students in Colombia and Mexico

This study examined descriptions of suicidal thoughts and behavior (STB) to identify risk and protective factors that may present in clinical settings among university students from Latin America. Our focus was on answering the following key questions: How are suicidal thoughts and behavior described? What are reasons for wanting to die and for living? What impact do STBs have on motivations to seek or avoid psychological treatment? To this end, 55 qualitative interviews were completed with university students from Colombia and Mexico who recently endorsed emotional difficulties in the World Mental Health International College Student (WMH-ICS) surveys. Interviews were coded to identify themes specific to STBs. Findings revealed insight on symptom presentations and consequences of STBs. Participants described uncontrollable somatic symptoms during periods of high suicide risk, which serves as a relevant clinical marker for health providers. An important reason for living was to avoid suffering for family, which was protective against suicide and motivates familial involvement in treatment planning. Participants sought solutions to emotional problems after experiencing STBs, including psychological treatment. Cultural stigma of mental illness induced feelings of shame and burden, which led to avolition, avoidance, and nondisclosure of symptom severity. This study provides insight into the utility of evaluating cultural context in (a) detecting antecedents to STBs frequently reported as somatic symptoms, (b) identifying protective factors against suicide, and (c) recognizing how stigma of mental illness and suicide, shame avoidance, and familism might influence personal motivations to seek or avoid help for emotional distress.

Prevalence and correlates of lifetime suicide attempt in obsessive-compulsive disorder with major depression

BACKGROUND

Little is known about specific obsessive-compulsive clinical features associated with lifetime history of suicide attempt in individuals with obsessive-compulsive disorder (OCD) and major depression.

METHODS

The study sample included 515 adults with OCD and a history of major depression. In exploratory analyses, we compared the distributions of demographic characteristics and clinical features in those with and without a history of attempted suicide and used logistic regression to evaluate the association between specific obsessive-compulsive clinical features and lifetime suicide attempt.

RESULTS

Sixty-four (12%) of the participants reported a lifetime history of suicide attempt. Those who had attempted suicide were more likely to report having experienced violent or horrific images (52% vs. 30%; p < 0.001). The odds of lifetime suicide attempt were more than twice as great in participants with versus without violent or horrific images (O.R. = 2.46, 95%, CI = 1.45-4.19; p < 0.001), even after adjustment for other risk correlates of attempted suicide, including alcohol dependence, post-traumatic stress disorder, parental conflict, excessive physical discipline, and number of episodes of depression. The association between violent or horrific images and attempted suicide was especially strong in men, 18-29 year olds, those with post-traumatic stress disorder, and those with particular childhood adversities.

CONCLUSIONS

Violent or horrific images are strongly associated with lifetime suicide attempts in OCD-affected individuals with a history of major depression. Prospective clinical and epidemiological studies are needed to elucidate the basis of this relationship.

Linking non-suicidal self-injury to psychopathology: The utility of transdiagnostic and DSM-based models

Non-suicidal self-injury (NSSI) is a significant public health concern, and its primary formal link to the universe of psychopathology content in DSM diagnoses has been mostly through borderline personality disorder (BPD). Recent research has produced ample evidence of weaknesses of diagnoses relative to transdiagnostic psychopathology dimensions, and found that NSSI-related variables like suicidality are best predicted by transdiagnostic versus diagnosis-based variables. These findings suggest a need to characterize how NSSI may relate to different forms of psychopathology classification constructs. We examined how transdiagnostic dimensions of psychopathology relate to NSSI, focusing on how transdiagnostic (shared) variance of dimensional psychopathology spectra might differentially explained the variance in NSSI relative to traditional DSM diagnoses. In two nationally representative United States samples (Ns = 34,653 and 36,309), we modeled the common distress-fear-externalizing transdiagnostic comorbidity model and investigated questions of predictive utility of these dimensional and categorical psychopathology structures. Transdiagnostic dimensions were superior in predicting NSSI compared to common DSM-IV and DSM-5 diagnoses. These dimensions accounted for 33.6-38.7 % of NSSI variance across all analyses in both samples. DSM-IV/DSM-5 diagnoses, however, demonstrated only modest incremental prediction of NSSI over and above the transdiagnostic dimensions. These results support a transdiagnostic reconceptualization of NSSI's links with psychopathology and highlight the importance of transdiagnostic dimensions for predicting clinical outcomes relating to self-injurious behaviors. Implications for research and clinical practice are discussed.

Timing of childhood adversities and self-injurious thoughts and behaviors in adolescence

Greater childhood adversity predicts a higher likelihood of later self-injurious thoughts and behaviors (SITB). There is little research focused on whether the timing of childhood adversity predicts SITB. The current research examined whether the timing of childhood adversity predicted parent- and youth-reported SITB at age 12 and 16 years in the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) cohort (n = 970). We found that greater adversity at age 11-12 years consistently predicted SITB at age 12 years, while greater adversity at age 13-14 years consistently predicted SITB at age 16 years. These findings suggest there may be sensitive periods during which adversity may be more likely to lead to adolescent SITB, which can inform prevention and treatment.

Fear of negative evaluation and suicidal ideation among college students: the moderating role of impulsivity-like traits

Objective: Fear of negative evaluation (FNE) is a key trait of social anxiety and has been linked to isolation and low self-esteem. Impulsivity has been shown to amplify the risk of socially anxious individuals engaging in risky behaviors such as suicidal behaviors; yet little research has examined associations between FNE and suicidality or the relationship between FNE and impulsivity. Participants/Methods: This study tested whether FNE was associated with suicidal ideation in a sample of 1,816 college students from 10 universities. Analyses also examined whether impulsivity-like traits moderated the relationship between FNE and suicidal ideation. Results: Results showed that FNE was significantly associated with suicidal ideation and the positive association between FNE and suicidal ideation was strongest among individuals with higher negative urgency and lower perseverance. Conclusions: These findings highlight FNE as an important risk factor of suicidal ideation in college students and illuminates potential influence of impulsivity on this relationship.

Deliberate self-harm in adolescents: A review of literature

Deliberate self-harm is a rising epidemic in the youth. This review examined the different self-harm behavior, approach to treatment, and the implication of such behaviors in the adolescent population in the academic literature. Using the PubMed database, we searched for specific terms related to different self-harm behaviors in Adolescents. The bibliography of the articles found relevant for the review was also screened. Each study's findings were taken with reference to our topic and findings were summarized. After reviewing the literature, we found that the prevalence of suicidal attempts was as high as 18% in the past year While the nonsuicidal attempts were as high as 31%. Risk factors associated with higher levels of suicide were bullying, loneliness and anxiety, tobacco and alcohol use, and weak family and social relationships. While the factors playing a protective role are being connected to school, having good social support, and attending school. There are very few studies focused on interventions related to suicide prevention in Adolescent and postvention programs. Out of the evidence available, the interventions are not focused on the target individuals and lack replicability. Self-harm is a major public health concern which needs to be understood holistically. The interventions aimed at preventing and managing self-harm behavior still need to be more targeted and precise. Other targets may include interventions suited to different phases of development, stopping the progression of the behavior to adulthood, including the varied population in such intervention, etc.

Cognitive-behavioral therapy for insomnia prevents and alleviates suicidal ideation: insomnia remission is a suicidolytic mechanism

STUDY OBJECTIVES

Insomnia is associated with elevated levels of suicidal thoughts and behaviors. Emerging evidence suggests that cognitive-behavioral therapy for insomnia (CBTI) may reduce suicidal ideation (SI). However, the role of digital therapeutics in both the alleviation and prevention of SI remains unclear, and treatment mechanisms facilitating SI reductions have not been clearly identified.

METHODS

A total of 658 adults with Diagnostic and Statistical Manual of Mental Disorders, 5th Edition insomnia disorder enrolled in a single-site randomized controlled trial evaluating the efficacy of digital CBTI relative to attention control. Outcomes were measured at pretreatment, posttreatment, and 1-year follow-up.

RESULTS

Before treatment, 126 patients endorsed SI (19.1% prevalence). Among those with baseline SI, CBTI patients reported lower SI rates at posttreatment (30.0% vs 54.5%, p = .005) and 1-year follow-up (29.6% vs 46.8%, p = .042) relative to control. PRODCLIN analysis estimated that half of suicidolytic effects of CBTI were mediated through insomnia remission. Among those without baseline SI, CBTI did not directly prevent new onset SI. However, insomnia remitters reported lower rates of new-onset SI at posttreatment relative to non-remitters (1.5% vs 6.5%, p = .009). Mediation analysis supported a significant indirect effect wherein CBTI increased the likelihood of insomnia remission, which was associated with SI prevention (αβ = -3.20, 95% CI = -5.74 to -0.87).

CONCLUSION

Digital CBTI reduces insomnia symptoms, which promotes SI alleviation and prevention. For nonsuicidal patients, digital CBTI may serve as a highly accessible monotherapy for improving sleep, thereby reducing the risk for SI. For suicidal patients, digital CBTI may be appropriately administered as an adjunct treatment to support mainline intervention more directly targeting suicidogenic thoughts.

Is Lethality Different between Males and Females? Clinical and Gender Differences in Inpatient Suicide Attempters

According to the gender paradox in suicidology, an important sex difference has been reported with a preponderance of females in nonfatal suicidal behavior and a preponderance of males in completed suicide. Furthermore, females and males present different risk factors for suicide. The present study explored possible clinical differences between male and female psychiatric inpatients who had recently attempted suicide. The study included 177 adult inpatients hospitalized following a suicide attempt at the University Psychiatric Clinic, Sant'Andrea Hospital, Sapienza University of Rome. Clinical features assessed included psychiatric diagnosis, method and lethality of suicide attempts using the Risk/Rescue Rating Scale, the history of suicide attempts, age at onset of psychiatric illness, the presence of substance or alcohol use, and the length of stay. The results found that males and females differed in the method used for the suicide attempt, the scores for risk and rescue, and the length of hospitalization post-suicide attempt. In conclusion, identifying gender characteristics of patients at higher risk of suicide is important for implementing specific suicide prevention strategies and reducing the risk of future suicidal behavior in psychiatric inpatients.

Childhood maltreatment and self-hatred as distinguishing characteristics of psychiatric patients with self-harm: A comparison with clinical and healthy controls

INTRODUCTION

Deliberate self-harm (DSH) is common in clinical populations. Childhood maltreatment (CM) and attitudes both towards oneself and towards DSH may be of importance for the development of DSH. This study aimed to test whether patients with DSH report more CM, more negative attitudes towards oneself and more positive attitudes towards DSH than a clinical and a healthy comparison group, and whether the effects of CM are mediated by negative attitudes towards oneself.

METHOD

Females with DSH and psychiatric disorders (n = 34), females without DSH but with psychiatric disorders (n = 31) and healthy female individuals (n = 29) were compared regarding DSH, CM, attitudes towards the self and attitudes towards self-harm.

RESULTS

Females with DSH reported more emotional abuse and more self-hatred as compared to both comparison groups. The effect of emotional abuse was mediated by self-hatred. The DSH-group had significantly more positive attitudes towards DSH than the healthy comparison group.

CONCLUSION

Self-hatred and CM in the form of emotional abuse may be distinguishing characteristics of female patients with DSH in psychiatric settings. The present results are compatible with the hypothesis that emotional abuse leads to DSH via self-hatred, but the cross-sectional nature of the study precludes any causal conclusions. The clinical utility of the results is discussed.

Children mirror adults for the worse: evidence of suicide rates due to air pollution and unemployment

Background

Every year, more than 700,000 people die due to suicide, one of the most common reasons for youth death. While many studies have revealed two main factors for suicidal behavior: impulsive suicidal behavior due to mental illness and financial stress, it is not clear what happens if individuals face deterioration of mental health and economic recession. This paper attempts to answer this question and how suicide rates are correlated with these factors.

Methods

We empirically investigate whether economic recessions and air pollution trigger suicides by examining Japan, a country with one of the highest suicide rates, from 2014 to 2021. We take advantage of the characteristics of the COVID-19 pandemic and the periods before the pandemic, when both economic recessions and reductions in air pollution occurred simultaneously. Using monthly and municipal- level data, we construct a triple difference model that takes air pollution and unemployment as treatments.

Results

Our findings show that high (upper half of each period) levels of air pollution and unemployment have substantial impacts on the suicide rates of adults (22.9% in the short term) and children (42.7% in the short term, 36.0% in the long term), indicating that the increase in suicide rates among children is almost twice as high as that among adults. Our study finds that unemployment and air pollution alone are not associated with increased suicide rates but their simultaneous occurrence triggers suicides during the pandemic.

Conclusions

Our study urges suicide prevention, particularly among children, as an essential consideration for public health. Furthermore, our results indicate the need for the government to allocate resources to recover air quality and the economy simultaneously during a recession to reduce suicide mortality of both child and adults.

Excess healthcare resource utilization and healthcare costs among privately and publicly insured patients with major depressive disorder and acute suicidal ideation or behavior in the United States

BACKGROUND

This study assessed the healthcare resource utilization (HRU) and cost burden of patients with major depressive disorder (MDD) and acute suicidal ideation or behavior (SIB; MDSI) versus those with MDD without SIB and those without MDD.

METHODS

Adults were selected from the MarketScan® Databases (10/2015-02/2020). The MDSI cohort received an MDD diagnosis within 6 months of a claim for acute SIB (index date). The index date was a random MDD claim in the MDD without SIB cohort and a random date in the non-MDD cohort. Patients had continuous eligibility ≥12 months pre- and ≥1 month post-index. HRU and costs were compared during 1- and 12-month post-index periods between MDSI and control cohorts matched 1:1 on demographics.

RESULTS

The MDSI cohort included 73,242 patients (mean age 35 years, 60.6% female, 37.2% Medicaid coverage). At 1 month post-index, the MDSI cohort versus the MDD without SIB/non-MDD cohorts had 12.8/67.2 times more inpatient admissions and 3.3/8.9 times more emergency department visits; they had 2.9 times more outpatient visits versus the non-MDD cohort (all p < 0.001). The MDSI cohort had incremental mean healthcare costs of $5255 and $6674 per-patient-month versus the MDD without SIB and non-MDD cohorts (all p < 0.001); inpatient costs drove up to 89.5% of incremental costs. At 12 months post-index, HRU and costs remained higher in MDSI versus control cohorts.

LIMITATIONS

SIB are underreported in claims; unobserved confounders may cause bias.

CONCLUSIONS

MDSI is associated with substantial excess healthcare costs driven by inpatient costs, concentrated in the first month post-index, and persisting during the following year.

A Longitudinal Study of Correlates, Discharge Disposition, and Rate of Re-presentation to Emergency Services of Adults who Engage in Non-suicidal Self-injury

OBJECTIVE

In DSM-5, non-suicidal self-injury (NSSI) and suicide attempts (SA) are classified as distinct disorders in the section of conditions for further study. However, some have questioned the validity of distinguishing NSSI from SA. The objective of this study was to longitudinally examine the correlates, discharge disposition, and rate of re-presentation to emergency services of adults who engaged in NSSI and compare them to (a) adults who engage in SA and (b) adults with no self-harm or suicidal ideation (SI).

METHOD

Data came from 4,772 presentations to adult psychiatric services in the emergency departments of tertiary care hospitals in Winnipeg, Canada between January 2009 and June 2012. Chart reviews were conducted for all presentations with NSSI (n = 158), and a sample of those with SA (n = 172) and no SH or SI (n = 173).

RESULTS

Among the adults who returned to emergency services, those who originally presented with SA re-presented significantly sooner than those who presented with NSSI. (χ²(1) = 7.457, p = 0.006). Those who originally presented with NSSI that returned to hospital did not return with repeat NSSI, but instead the majority re-presented with suicidal thoughts and SA. Further, those who re-presented with NSSI and SA were less likely to be hospitalized or to receive a referral to mental health services, and more likely to be discharged to usual care at time of initial presentation.

CONCLUSIONS

Overall, these findings indicate a trajectory of escalation of self-harm behavior for certain people who engage in NSSI, especially those who re-present to emergency services.HIGHLIGHTSA quarter of people with self-harm re-present to emergency services within four-and-a-half years.Those with suicide attempts re-presented significantly sooner than non-suicidal self-injury.There is a need for increased interventions in emergency services for those with self-harm.

Psychometric properties, stability, and predictive validity of the Korean version of the Prolonged Grief Disorder Scale (PG-13-K): A longitudinal study among bereaved Koreans

This study aims to investigate the psychometric properties, stability, and predictive validity of the PG-13-K. Two subsamples were used: the first subsample (N = 153), participated at Time 1 only, and the second subsample (N = 184) participated at both Time 1 and Time 2. At each time point, reliability, test-retest reliability, and validity were adequate, and the hypothesized two-factor model indicated good to excellent fit. Moreover, the PG-13-K was able to predict the correlation between prolonged grief disorder (PGD) and negative psychological factors. The PG-13-K is a useful and valid instrument for measuring PGD symptoms in Korean settings.

Adverse Childhood Experiences, Suicidal/Self-Harming Thoughts, and Suicide Attempts Among LGB and Heterosexual Utahns

Current research suggests that sexual minorities living in Utah may be at higher risk for experiencing suicidal/self-harming thoughts and suicide attempts than heterosexuals in Utah. However, to date no research has been conducted examining potential reasons sexual minorities living in Utah may be at higher risk. Using two representative samples of Utahns, we examine (a) disparities in adverse childhood experiences (ACEs) between sexual minorities and heterosexual Utahn, (b) how ACEs and sexual orientation may predict recent suicidal/self-harming thoughts and lifetime prevalence of suicide attempts, and (c) how sexual orientation and ACEs might interact to predict suicidal outcomes. Results with each sample showed that sexual minority Utahns reported higher levels of ACEs and suicidal/self-harming thoughts than heterosexual Utahns. Both sexual orientation and ACEs uniquely predicted suicidality when both were entered into regression models, but no interaction effects were found between these predictors.

Peripheral and neural correlates of self-harm in children and adolescents: a scoping review

BACKGROUND

Self-harm in children and adolescents is difficult to treat. Peripheral and neural correlates of self-harm could lead to biomarkers to guide precision care. We therefore conducted a scoping review of research on peripheral and neural correlates of self-harm in this age group.

METHODS

PubMed and Embase databases were searched from January 1980-May 2020, seeking English language peer-reviewed studies about peripheral and neural correlates of self-harm, defined as completed suicide, suicide attempts, suicidal ideation, or non-suicidal self-injury (NSSI) in subjects, birth to 19 years of age. Studies were excluded if only investigating self-harm in persons with intellectual or developmental disability syndromes. A blinded multi-stage assessment process by pairs of co-authors selected final studies for review. Risk of bias estimates were done on final studies.

RESULTS

We screened 5537 unduplicated abstracts, leading to the identification of 79 eligible studies in 76 papers. Of these, 48 investigated peripheral correlates and 31 examined neural correlates. Suicidality was the focus in 2/3 of the studies, with NSSI and any type of self-harm (subjects recruited with suicidality, NSSI, or both) investigated in the remaining studies. All studies used observational designs (primarily case-control), most used convenience samples of adolescent patients which were predominately female and half of which were recruited based on a disorder. Over a quarter of the specific correlates were investigated with only one study. Inter-study agreement on findings from specific correlates with more than one study was often low. Estimates of Good for risk of bias were assigned to 37% of the studies and the majority were rated as Fair.

CONCLUSIONS

Research on peripheral and neural correlates of self-harm is not sufficiently mature to identify potential biomarkers. Conflicting findings were reported for many of the correlates studied. Methodological problems may have produced biased findings and results are mainly generalizable to patients and girls. We provide recommendations to improve future peripheral and neural correlate research in children and adolescents, ages 3-19 years, with self-harm.

Maladaptive Daydreaming: Epidemiological Data on a Newly Identified Syndrome

Background

Maladaptive Daydreaming (MD) is a recently identified psychological disorder, characterized by excessively and addictively engaging in vivid, narrative, intensely emotional fantasy activity, at times with the aid of music and/or repetitive movements, causing distress and functional impairment. Over 100,000 self-diagnosed individuals are active online and thousands of them have been researched; yet there are no studies using clinical interviews on large, systematic general (non-MD) samples, to assess the estimated prevalence of this suggested disorder, and establish norms for its main psychometric tool.

Methods

Four independent Israeli samples (three student samples, and one sample representing the general Jewish-Israeli population; total N = 1,023) self-reported MD. In two samples, those exceeding the cutoff score for suspected MD were invited for a structured clinical interview.

Results

The skewness of most items of the 16-item Maladaptive Daydreaming Scale (MDS-16) supports the notion of MD as a binary construct rather than a normally distributed trait. In the community sample, 4.2% exceeded the cutoff for suspected MD. Rates were higher when focusing on the young adult age group or student samples (5.5-8.5%), suggesting a likely age effect. Following clinical interviews, only 60% of interviewed respondents met criteria for diagnosis, suggesting a true point-prevalence of 2.5% in the Israeli-Jewish population.

Conclusions

This is the first systematic clinical evaluation of the prevalence of MD. In an Israeli sample, a point-prevalence of 2.5% was found, like several other internalizing psychiatric syndromes. This result, along with the Non-normal nature of item distribution, both support the validity of MD as a psychological disorder, which should be considered as a potential addition to future psychiatric diagnostic manuals.

Correlates of deliberate self-harm among youth with bipolar disorder

OBJECTIVE

Youth with bipolar disorder (BD) are at high risk for deliberate self-harm (DSH) and suicide. However, research regarding factors associated with DSH, a key suicide risk factor, among youth with BD is limited. In a population-based sample of youth with BD, we therefore investigated associations between demographic, clinical, and service utilization factors and DSH incidence and compared suicide, unintentional injury, and all-cause mortality to the general population.

METHOD

We analyzed a retrospective cohort of youth aged 5 to 19 years with a new BD episode between 2010 and 2017 (n = 25,244) using Ohio Medicaid claims and death certificate data. Cox proportional hazards models examined associations between different factors and DSH. Mortality rates were compared to the general population using standardized mortality ratios.

RESULTS

During follow-up, 1,517 (6.0%) youth had at least one DSH event. Older index age, female sex, comorbid psychiatric/medical conditions, prior DSH/suicidal ideation, and prior ER mental healthcare were associated with increased DSH risk. Prior DSH was most strongly associated with increased DSH risk for 3 months after a new BD episode. Being non-Hispanic Black (vs. White, non-Hispanic) and prior psychiatric hospitalization were associated with decreased DSH hazard. DSH risk was highest for 3 months after a new BD episode. Suicide, unintentional injury, and all-cause mortality rates were elevated in youth with BD.

LIMITATIONS

May not generalize to other states or non-Medicaid populations; claims data cannot distinguish suicidal intent of self-harm CONCLUSION: Early intervention following a new BD episode, particularly among high-risk groups, is key to prevent DSH.

Suicidality Among Transgender Youth: Elucidating the Role of Interpersonal Risk Factors

Data indicate that 82% of transgender individuals have considered killing themselves and 40% have attempted suicide, with suicidality highest among transgender youth. Using minority stress theory and the interpersonal theory of suicide, this study aims to better understand suicide risk among transgender youth. The present study examines the influence of intervenable risk factors: interpersonal and environmental microaggressions, internalized self-stigma, and adverse childhood experiences (ACEs), and protective factors: school belonging, family support, and peer support on both lifetime suicide attempts and past 6-month suicidality in a sample of transgender youth (n = 372). SPSS 22 was utilized to examine the impact of the independent variables on both suicidality and lifetime suicide attempt through two separate logistic regressions. Fifty six percent of youth reported a previous suicide attempt and 86% reported suicidality. Logistic regressions indicated that models for both lifetime suicide attempts and suicidality were significant. Interpersonal microaggressions, made a unique, statistically significant contribution to lifetime suicide attempts and emotional neglect by family approached significance. School belonging, emotional neglect by family, and internalized self-stigma made a unique, statistically significant contribution to past 6-month suicidality. Results have significant practice and policy implications. Findings offer guidance for practitioners working with parents and caregivers of trans youth, as well as, for the creation of practices which foster interpersonal belonging for transgender youth.

Communicating distress: suicide threats/gestures among clinical and community youth

Although self-injurious thoughts and behaviors are a global health concern, little is known about suicidal threat/gesture(s) where a person leads others to believe they want to end their lives when they have no intention to do so. This study assessed the lifetime prevalence of self-injurious thoughts and behaviors among both community adolescents (n = 1117) and in clinical youth (n = 191). Suicide threats/gestures were common among youth; 12.2% of community adolescents and 18.0% of clinical youth reporting having made a suicide threat/gesture, most commonly in the context of other self-injurious thoughts and behaviors. Across both samples, suicide threats/gestures were not uniquely associated with suicide attempts, and youth who reported suicide threats/gestures in the context of a history of self-harm or suicide plan(s) were no more likely to report a history of suicide attempt(s). Suicide threats/gestures were distinguished from suicide attempts in that they primarily fulfilled positive social functions, rather than autonomic functions. Findings suggest that suicidal threats/gestures are common in both community and clinical youth, and are not uniquely associated with suicide attempts, but rather function to communicate distress to others.

Effect and neural mechanisms of the transcutaneous vagus nerve stimulation for relapse prevention in patients with remitted major depressive disorder: protocol for a longitudinal study

INTRODUCTION

After the first episode, patients with remitted major depressive disorder (MDD) have a 60% chance of experiencing a second episode. There are currently no accepted, effective methods to prevent the recurrence of MDD in remission. Transcutaneous vagus nerve stimulation (taVNS) is a non-invasive, safe and economical approach based on the efficacy of VNS in improving clinical depression symptoms. This clinical trial will study the efficacy of taVNS in preventing MDD relapse and investigate the underlying mechanisms of this.

METHODS AND ANALYSIS

We will conduct a multicentre, randomised, patient-blinded and evaluators double-blinded trial. We will randomise 90 eligible participants with recurrent MDD in remission in a 1:1 ratio into a real or sham taVNS group. All participants will be given six biopsychosocial assessments: proinflammatory cytokines, serum monoamine neurotransmitters, cognition, affective neuropsychology, multimodal neuroimaging and endocrinology. After the baseline measurements, all participants will be given corresponding interference for 6 months and then complete a 1-year follow-up. The assessments will be performed three times: at baseline, post-treatment and at the end of 1-year follow-up (except for multimodal MRI scanning, which will be conducted at the first two assessments only). Change in 17-item Hamilton Depression Rating Scale scores for MDD is the primary outcome parameter.

ETHICS AND DISSEMINATION

The study protocol was approved by the Medical Ethical Committee of Beijing Hospital of Traditional Chinese Medicine on 18 January 2019 (2018BL-076). The trial results will be published in peer-reviewed journals and at conferences.

The relationship between the therapeutic alliance in psychotherapy and suicidal experiences: A systematic review

It is well established that there is a fundamental need to develop a robust therapeutic alliance to achieve positive outcomes in psychotherapy. However, little is known as to how this applies to psychotherapies which reduce suicidal experiences. The current narrative review summarizes the literature which investigates the relationship between the therapeutic alliance in psychotherapy and a range of suicidal experiences prior to, during and following psychotherapy. Systematic searches of MEDLINE, PsycINFO, Web of Science, EMBASE and British Nursing Index were conducted. The search returned 6472 studies, of which 19 studies were eligible for the present review. Findings failed to demonstrate a clear link between suicidal experiences prior to or during psychotherapy and the subsequent development and maintenance of the therapeutic alliance during psychotherapy. However, a robust therapeutic alliance reported early on in psychotherapy was related to a subsequent reduction in suicidal ideation and attempts. Study heterogeneity, varied sample sizes and inconsistent reporting may limit the generalizability of review findings. Several recommendations are made for future psychotherapy research studies. Training and supervision of therapists should not only highlight the importance of developing and maintaining the therapeutic alliance in psychotherapy when working with people with suicidal experiences but also attune to client perceptions of relationships and concerns about discussing suicidal experiences during therapy.

Distress tolerance as a moderator of the dynamic associations between interpersonal needs and suicidal thoughts

BACKGROUND

Identifying the interaction between dispositional and dynamic risk factors is necessary in understanding, predicting, and managing suicide risk. Interpersonal factors have consistently been linked to suicidal ideation over short-term periods. Additionally, distress tolerance may be a relevant dispositional protective factor against stressful events.

METHODS

Seven hundred and seventeen psychiatric inpatients (Male = 30.31%, Average Age = 40.71 years, Min = 14, Max = 82) self-reported their distress tolerance at hospital admission, and interpersonal needs and suicidal ideation on a daily basis. Dynamic structural equation modelling was used to examine whether within-level dynamics were moderated by distress tolerance.

RESULTS

Both perceived burdensomeness and thwarted belongingness were significantly associated with same-day suicidal ideation. Higher distress tolerance was associated with weaker daily associations between suicidal ideation and both perceived burdensomeness and thwarted belongingness. Distress tolerance was also associated with lower variability in suicidal ideation. Moderating effects were also evident when lifetime suicide attempts were added as a covariate, which was associated with stronger associations between interpersonal dysfunction and suicidal ideation, and higher variability in ideation.

CONCLUSIONS

Distress tolerance may be important to consider when examining the dynamic relationships between suicidal ideation and proximal factors. Psychotherapy that specifically targets distress tolerance may be effective in reducing reactivity to interpersonal stressors.

Cross-national examination of adolescent suicidal behavior: a pooled and multi-level analysis of 193,484 students from 53 LMIC countries

INTRODUCTION

Suicide is a leading cause of adolescent mortality worldwide. We aimed to estimate the prevalence and identify individual-level and country-level factors which might explain the variability in suicidal behavior among students in 53 low to middle income countries.

METHODS

We used data on adolescents aged 12-16 years from the Global School-based Student Health Surveys from 2009-2016. The suicidal behaviors investigated included suicide ideation, suicidal planning and suicide attempt. The prevalence was estimated for 53 countries, while a multilevel logistic regression analysis (33 countries) was used to investigate the associations of these behaviors with individual and country-level contextual risk factors. The contextual variables included the Gini Coefficient, Gross Domestic Product per capita, pupil-to-teacher ratios, population density, homicide rates, law criminalizing suicide and the night light index.

RESULTS

The overall prevalence of suicide ideation, making a plan and suicide attempt were 10.4%, 10.3% and 11.0%, respectively. The highest prevalence rates reported were from the Americas. The strongest risk factors associated with suicidal behavior included anxiety, loneliness, no close friends and the substance abuse. Among the country level variables, the night light index was associated with making a suicide plan and attempting suicide.

CONCLUSION

The non-significant country level findings were not entirely surprising given the mixed results from prior studies. Additional knowledge is thus achieved with regard to country level factors associated with suicidal behavior across adolescent populations.

Optimal PAI-A Cutoffs to Determine Risk for Non-Suicidal Self-Injury (NSSI) and Suicide-Related Behavior (SRB) among At-Risk Adolescents

OBJECTIVE

This study examines psychopathology and personality correlates of non-suicidal self-injury (NSSI) and suicide-related behavior (SRB) in an understudied sample of adolescents who have exhibited behaviors (e.g., delinquent acts, premature high school termination) that place them at-risk for poor psychosocial outcomes.

METHOD

Participants included a predominantly White male sample of 182 adolescents (M_age = 16.82 years). In addition to information about NSSI and SRB histories, participants self-reported various facets of personality and psychopathology on the Personality Assessment Inventory-Adolescent (PAI-A).

RESULTS

Logistic regression analyses indicated that the Suicidal Ideation (SUI) scale on the PAI-A was the strongest predictor of both NSSI and SRB history, as it outperformed other relevant PAI-A scales and the Suicide Potential Index (SPI), an aggregate scale that was designed to assess for suicide risk using the PAI for adults. Receiver operating characteristic (ROC) curve analyses were also conducted to determine optimal cutoff scores for significant PAI-A predictors.

CONCLUSIONS

Findings from the current study can be used to identify NSSI and SRB risk and target these life-threatening behaviors when working with at-risk adolescents.HighlightsPAI-A SUI outperformed other PAI-A variables in predicting NSSI and SRB risk.PAI SPI did not perform as well in adolescents compared to adult samples.Cutoff scores in the current sample were well below those in the PAI-A manual.

Differences in Comorbidities Between Children and Youth With Suicide Attempts Versus Ideation Presenting to the Emergency Department

OBJECTIVE

The aim of this work was to explore identified risk factors for suicidal ideations and attempts and the differences in these risk factors between emergency department encounters among youth seeking medical care for suicide attempt and those with suicidal ideation.

METHOD

This was a retrospective analysis of suicide-related claims for emergency department visits from nine state-level Healthcare Cost and Utilization Project databases for youth aged 5 through 19 years. Risk factors were estimated by identifying comorbidities recorded in first five diagnosis codes. Odds ratios comparing rates of these comorbidities in encounters for suicide attempts compared to encounters for suicidal ideation were estimated using multivariate logistic regression.

RESULTS

In all, 169,047 encounters for suicide-related behavior were identified. We found higher odds of concurrent anxiety, personality disorders, and alcohol-related diagnoses and lower odds of a comorbid psychosis diagnosis, attention deficit hyperactivity disorder, and other substance-related diagnoses in the population of suicide attempters compared to patients with suicidal ideation alone.

CONCLUSION

The odds of diagnoses of specific comorbidities differed in youth encounters for suicide attempts compared to encounters for suicidal ideation.

How we ask matters: The impact of question wording in single-item measurement of suicidal thoughts and behaviors

The present study aimed to extend prior literature on single-item assessment by examining response consistency (1) between several commonly used single-item assessments of suicidal ideation, planning, and attempts, and (2) across three timeframes (past month, past year, and lifetime) commonly employed in the literature. Participants (N = 613) were recruited from an online community, Amazon Mechanical Turk (mTurk). Participants were administered three sets of four distinct single-items assessing suicidal ideation, suicidal planning, and suicide attempt history, respecitvely. Items were drawn from well-known large-scale studies (e.g., National Comorbidity Survey; World Health Organization Mental Health Survey Initiative, Youth Risk Behavior Survey) and commonly used suicide risk assessments (i.e., Self-Injurious Thoughts and Behaviors Interview). Through examinations of intraclass correlations and confirmatory factor analyses, findings suggested mixed response agreement across most outcomes and timeframes. Response inconsistency among items assessing suicidal ideation and among items assessing suicidal planning were partly attributed to minor, yet important, language differences. Given findings that even minor language changes in suicidal ideation and planning items may inflate or restrict prevalence estimates in a meaningful way, it will be important for researchers and clinicians alike to pay close attention to the wording of single items in designing research studies, interpreting findings, and assessing patient risk.

On the Genetic and Environmental Relationship Between Suicide Attempt and Death by Suicide

OBJECTIVE

The authors examined the extent to which the genetic and environmental etiology of suicide attempt and suicide death is shared or unique.

METHODS

The authors used Swedish national registry data for a large cohort of twins, full siblings, and half siblings (N=1,314,990) born between 1960 and 1990 and followed through 2015. They conducted twin-family modeling of suicide attempt and suicide death to estimate heritability for each outcome, along with genetic and environmental correlations between them. They further assessed the relationship between suicide attempt by young people compared with adults.

RESULTS

In bivariate models, suicide attempt and death were moderately heritable among both women (attempt: additive genetic variance component [A]=0.52, 95% CI=0.44, 0.56; death: A=0.45, 95% CI=0.39, 0.59) and men (attempt: A=0.41, 95% CI=0.38, 0.49; death: A=0.44, 95% CI=0.43, 0.44). The outcomes were substantially, but incompletely, genetically correlated (women: rA=0.67, 95% CI=0.55, 0.67; men: rA=0.74, 95% CI=0.63, 0.87). Environmental correlations were weaker (women: rE=0.36, 95% CI=0.29, 0.45; men: rE=0.21, 95% CI=0.19, 0.27). Heritability of suicide attempt was stronger among people ages 10-24 (A=0.55-0.62) than among those age 25 and older (A=0.36-0.38), and the genetic correlation between attempt during youth and during adulthood was stronger for women (rA=0.79, 95% CI=0.72, 0.79) than for men (rA=0.39, 95% CI=0.26, 0.47).

CONCLUSIONS

The genetic and environmental etiologies of suicide attempt and death are partially overlapping, exhibit modest sex differences, and shift across the life course. These differences must be considered when developing prevention efforts and risk prediction algorithms. Where feasible, suicide attempt and death should be considered separately rather than collapsed, including in the context of gene identification efforts.

Comorbid alcohol-related problems and suicidality disproportionately impact men and emerging adults among individuals with depressive symptoms

OBJECTIVE

Depressive disorders are common among adults with alcohol use disorder and with suicidality; however, demographic differences in comorbid alcohol use disorder, binge drinking, and suicidality are understudied. The objective of this study was to determine the extent to which comorbid suicidality and alcohol use disorders and comorbid suicidality and binge drinking differ by age and gender among adults with depressive symptoms.

METHOD

The sample included adults (unweighted N=29,460) in the United States who completed the 2015-2018 National Survey of Drug Use and Heath and screened positively for depression. Gender and age groups odds of alcohol use disorder only, suicidality only, and alcohol use disorder+suicidality were compared to neither problem. Similar analyses were conducted for binge drinking.

RESULTS

Men showed disproportional odds of alcohol use disorder only, all suicidality and alcohol use disorder comorbidities, and binge drinking+active suicidal ideation than women. Emerging adults showed higher odds of: passive and active suicidal ideation only and suicidality+alcohol use disorder than adults 35 and older; binge drinking only, binge drinking+passive suicidal ideation, and binge drinking+active suicidal ideation than all older adults; binge drinking+suicide planning and binge drinking+attempts than adults 50 and older.

LIMITATIONS

Because participants all reported depression symptoms either at the subclinical or clinical level, demographic differences in suicidality, alcohol use disorder, and binge drinking found in this study cannot be generalized to non-depressed samples.

CONCLUSIONS

Treatment providers should be aware of disproportionately higher odds of comorbid suicidality and alcohol use disorder, and suicidality and binge drinking among men and emerging adults.
