Mental disorders, comorbidity and suicidal behavior: results from the National Comorbidity Survey Replication

Assessing suicide risk in patients with obsessive-compulsive disorder: a dimensional approach

OBJECTIVES

Although an association has been found recently between obsessive-compulsive disorder and an increased risk of suicide, the prevalence of both suicidal ideation and attempts vary considerably and are generally assessed categorically. Our aims were to evaluate the prevalence of suicidal ideation and behaviors using a dimensional approach.

METHODS

The sample included 129 patients with obsessive-compulsive disorder. Suicidality was assessed by administering the Columbia-Suicide Severity Rating Scale. Logistic and linear regressions were used to examine predictors of suicidal ideation, severe suicidal ideation, and suicidal behavior.

RESULTS

The lifetime prevalence of suicidal ideation and behaviors were 64.3% and 16.3%, respectively. Lifetime suicidal ideation was associated with the number of stressful life events, duration of illness, Hamilton Rating Scale for Depression scores, and family history of mood disorders. A family history of obsessive-compulsive disorder was associated with a lower probability of lifetime suicidal ideation. Severe suicidal ideation was related to greater severity of the most stressful life event, Hamilton Rating Scale for Depression scores, and longer duration of untreated illness. The probability of lifetime suicidal behavior was related to Hamilton Rating Scale for Anxiety scores, symmetry obsessions, and washing and checking compulsions. The probability of lifetime non-suicidal self-injurious behaviors was related to Hamilton Rating Scale for Anxiety scores.

CONCLUSIONS

Recognizing predictors of suicidal ideation/behavior is crucial to identifying patients at greater risk.

Non-suicidal self-injury, suicidal thoughts and behaviors in individuals with an eating disorder relative to healthy and psychiatric controls: A systematic review and meta-analysis

OBJECTIVE

Eating disorders (ED) may be associated with an increased prevalence of non-suicidal self-injury (NSSI) and suicidal thoughts and behaviors (STBs) relative to healthy (HC) and psychiatric (PC) controls. However, precise estimates of differences in prevalence between individuals with EDs and controls are unclear. We compared the prevalence of NSSI, suicidal ideation (SI), suicide attempts (SA), and deaths by suicide in controls and individuals with EDs.

METHOD

We searched MEDLINE, PsycINFO, EMBASE, and CINAHL for peer-reviewed publications reporting the prevalence of NSSI and/or STBs in EDs and HC or PC group (PROSPERO: CRD42021286754). A series of random-effects meta-analyses were conducted to estimate pooled odds ratios (ORs) for NSSI, SI, SA, and death by suicide in EDs.

RESULTS

Across 32 studies, individuals with an ED had a significantly increased prevalence of NSSI (HC: OR = 6.85 [95% CI: 3.60, 13.04]; PC: OR = 2.74 [95% CI: 1.49, 5.06]), SI (HC: OR = 3.63 [95% CI: 2.43, 5.41]; PC: OR = 3.10 [95% CI: 2.01, 4.78]), and SA (HC: OR = 5.16 [95% CI: 4.27, 6.24]; PC: OR = 1.37 [95% CI: 0.37, 4.99]) relative to HC and PC groups. A 2.93-times increased odd of death by suicide did not achieve statistical significance. There was a high-level of heterogeneity between studies.

DISCUSSION

Our findings indicate that ED populations have an increased prevalence of NSSI, SI, and SA but not death by suicide compared to controls and emphasize the need for effective clinical strategies to address these behaviors in ED populations.

PUBLIC SIGNIFICANCE

This review provides evidence for an increased prevalence of non-suicidal self-injury, suicidal ideation, and suicide attempts in populations with eating disorders compared to controls. Our findings emphasize the need for effective clinical strategies to address these behaviors in patients with eating disorders.

Occurrence and Severity of Suicidal Ideation in Adults With Neurofibromatosis Participating in a Mind-Body RCT

BACKGROUND

Emotional distress can lead to suicidal ideation and potentially suicide completion, yet there is very little literature on suicidal ideation in individuals with a diagnosis of neurofibromatosis (NF; NF1, NF2, and schwannomatosis).

OBJECTIVE

To examine the baseline occurrence, severity, and clinical correlates of suicidal ideation in adults with NF.

METHOD

Individuals with NF (N = 220) completed assessments measuring depression (Patient Health Questionnaire-9), anxiety (Generalized Anxiety Disorder-7), perceived stress (Perceived Stress Scale-10), pain (Graded Chronic Pain Scale and PROMIS Pain Interference Short Form 8a), and general quality of life (World Health Organization Quality of Life-Brief version) before beginning a two-arm, single-blind randomized control trial of a live-video mind-body program for stress management and resiliency.

RESULTS

Nineteen percent (n = 42) of the individuals experienced suicidal ideation (ie, >0; ideation present several days or greater). More individuals with NF2 experienced suicidal ideation compared with those with NF1 or schwannomatosis. All of the clinical variables except pain intensity were significantly correlated ( P < 0.01) with greater suicidal ideation. Suicidal ideation in individuals with NF was comparable to or higher than that in other medical populations (eg, cancer, dermatological, neurologic). Depression and poor psychological quality of life significantly increased the risk for suicidal ideation.

CONCLUSION

Suicidal ideation was relatively prevalent in individuals with NF seeking participation in a mind-body randomized controlled trial. NF clinicians should be prepared to discuss these concerns and provide resources when suicidal ideation is present.

Inter-relationships of depressive and anxiety symptoms with suicidality among adolescents: A network perspective

BACKGROUND

Persons with suicidality including suicidal ideation (SI), suicide plans (SP) and/or suicide attempts (SA) are at higher risk for future suicide than those without suicidality. To reduce the risk of future suicide, it is important to understand symptoms of emotional distress that have the strongest links with SI, SP and SA. This network analysis examined item-level relations of depressive and anxiety symptoms with suicidality among adolescents during the COVID-19 pandemic.

METHODS

Adolescents between 12 and 20 years of age were assessed with the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), and individual binary reponse (no/yes) items assessing SI, SP, and SA during the pandemic. The structure of depressive symptoms, anxiety symptoms and suicidality was characterized using "Expected Influence" and "Bridge Expected Influence" as centrality indices in the symptom network. Network stability was tested using a case-dropping bootstrap procedure. Node-specific predictive betweenness was computed to examine short paths of anhedonia, other depressive symptoms and anxiety symptoms with suicidality. A Network Comparison Test (NCT) was conducted to examine whether network characteristics differed based on gender.

RESULTS

Prevalence rates of depressive symptoms, anxiety symptoms, and suicidality were 44.60 % (95% confidence interval (CI) = 41.53-47.67 %), 31.12 % (95%CI = 28.26-33.98 %), and 16.95 % (95%CI = 14.63-19.26 %), respectively, in the study sample. The network analysis identified GAD3 ("Worry too much") as the most central symptom, followed by GAD6 ("Irritability") and PHQ6 ("Guilt") in the sample. Additionally, PHQ6 ("Guilt"), GAD6 ("Irritability"), and PHQ2 ("Sad mood") were bridge nodes linking depressive and anxiety symptoms with suicidality. A flow network indicated that the connection between S ("Suicidality") and PHQ6 ("Guilt") reflected the strongest connection, followed by connections of S ("Suicidality") with GAD2 ("Uncontrollable worrying"), and S ("Suicidality") with PHQ2 ("Sad mood"). Finally, PHQ2 ("Sad mood") was the main bridge node linking anhedonia with other depressive and anxiety symptoms and suicidality in the sample.

CONCLUSIONS

Findings highlight the potential importance of reducing specific depressive and anxiety symptoms as possible means of reducing suicidality among adolescents during the pandemic. Central symptoms and key bridge symptoms identified in this study should be targeted in suicide prevention for at-risk adolescents.

Association of sociodemographic, proximal, and distal clinical factors with current suicidal ideation: Findings from a nonclinical sample of young adults

BACKGROUND

Accumulating evidence indicates that a variety of distal and proximal factors might impact a risk of suicide. However, the association between both groups of factors remains unknown. Therefore, in the present study, we aimed to investigate the interplay between distal and proximal correlates of the current suicidal ideation.

METHODS

A total of 3,000 individuals (aged 18-35 years, 41.7% males), who had reported a negative history of psychiatric treatment, were enrolled through an online computer-assisted web interview. Self-reports were administered to measure: (a) distal factors: a history of childhood trauma (CT), reading disabilities (RDs), symptoms of attention-deficit/hyperactivity disorder (ADHD), lifetime history of non-suicidal self-injury (NSSI), lifetime problematic substance use as well as family history of schizophrenia and mood disorders; (b) proximal factors: depressive symptoms, psychotic-like experiences (PLEs), and insomnia; and (c) sociodemographic characteristics.

RESULTS

Suicidal ideation was directly associated with unemployment, being single, higher level of RD, lifetime history of NSSI as well as higher severity of PLEs, depression, and insomnia. The association of distal factors with suicidal ideation was fully (a history of CT and symptoms of ADHD) or partially (a history of NSSI and RD) mediated by proximal factors (PLEs, depression, and insomnia).

CONCLUSIONS

Main findings from this study posit the role of distal factors related to neurodevelopmental disorders, CT and NSSI in shaping suicide risk. Their effects might be partially or fully mediated by depression, PLEs, and insomnia.

Neural processes of inhibitory control in American Indian peoples are associated with reduced mental health problems

American Indians (AI) experience disproportionately high prevalence of suicide and substance use disorders (SUD). However, accounting for risk burden (e.g. historical trauma and discrimination), the likelihood of mental health disorders or SUD is similar or decreased compared with the broader population. Such findings have spurred psychological research examining the protective factors, but no studies have investigated its potential neural mechanisms. Inhibitory control is one of the potential neurobehavioral construct with demonstrated protective effects, but has not been examined in neuroimaging studies with AI populations specifically. We examined the incidence of suicidal thoughts and behaviors (STB) and SUD among AI (n = 76) and propensity matched (sex, age, income, IQ proxy and trauma exposure) non-Hispanic White (NHW) participants (n = 76). Among the AI sample, functional magnetic resonance imaging (fMRI) data recorded during the stop-signal task (SST) was examined in relation to STB and SUDs. AIs relative to NHW subjects displayed lower incidence of STB. AIs with no reported STBs showed greater activity in executive control regions during the SST compared with AI who endorsed STB. AI without SUD demonstrated lower activity relative to those individual reporting SUD. Results are consistent with a growing body of literature demonstrating the high level of risk burden driving disparate prevalence of mental health concerns in AI. Furthermore, differential activation during inhibitory control processing in AI individuals without STB may represent a neural mechanism of protective effects against mental health problems in AI. Future research is needed to elucidate sociocultural factors contributing protection against mental health outcomes in AIs and further delineate neural mechanisms with respect to specific concerns (e.g. SUD vs STB).

Sex differences in amygdalohippocampal oscillations and neuronal activation in a rodent anxiety model and in response to infralimbic deep brain stimulation

Introduction

Depression and anxiety are highly comorbid mental disorders with marked sex differences. Both disorders show altered activity in the amygdala, hippocampus, and prefrontal cortex. Infralimbic deep brain stimulation (DBS-IL) has anxiolytic and antidepressant effects, but the underlying mechanisms remain unclear. We aimed to contribute to understanding sex differences in the neurobiology of these disorders.

Methods

In male and female rats, we recorded neural oscillations along the dorsoventral axis of the hippocampus and the amygdala in response to an anxiogenic drug, FG-7142. Following this, we applied DBS-IL.

Results

Surprisingly, in females, the anxiogenic drug failed to induce most of the changes observed in males. We found sex differences in slow, delta, theta, and beta oscillations, and the amygdalo-hippocampal communication in response to FG-7142, with modest changes in females. Females had a more prominent basal gamma, and the drug altered this band only in males. We also analyzed c-Fos expression in both sexes in stress-related structures in response to FG-7142, DBS-IL, and combined interventions. With the anxiogenic drug, females showed reduced expression in the nucleus incertus, amygdala, septohippocampal network, and neocortical levels. In both experiments, the DBS-IL reversed FG-7142-induced effects, with a more substantial effect in males than females.

Discussion

Here, we show a reduced response in female rats which contrasts with the higher prevalence of anxiety in women but is consistent with other studies in rodents. Our results open compelling questions about sex differences in the neurobiology of anxiety and depression and their study in animal models.

Hospital inpatient suicides: A retrospective comparison between psychiatric and non-psychiatric inpatients in Milan healthcare facilities

INTRODUCTION

Inpatient suicide in hospitals is a worrying phenomenon that has received little attention. This study retrospectively explored the socio-demographic, clinical, and suicide-related characteristics of hospital inpatient suicides in Milan, Italy, which were collected at the Institute of Forensic Medicine during a twenty-eight-year period (1993-2020). In particular, this study compared the features of hospital inpatient suicides in patients with and without psychiatric diagnoses.

METHODS

Data were collected through the historical archive, annual registers, and autopsy reports, in certified copies of the originals deposited with the prosecutors of the courts.

RESULTS

Considering the global sample, inpatients were mainly men (N = 128; 64.6%), with a mean age of 56.7 years (SD ± 19.8), of Italian nationality (N = 176; 88.9%), admitted to non-psychiatric wards (N = 132; 66.7%), with a single illness (N = 111; 56.1%), treated with psychotropic medications (N = 101; 51%), who used violent suicide methods (N = 177; 89.4%), died of organic injuries (N = 156; 78.8%), and outside the buildings (N = 114; 72.7%). Comparing psychiatric and non-psychiatric inpatients, suicide cases with a non-psychiatric diagnosis were predominantly men (N = 48; 76.2%), hospitalized in non-psychiatric wards (N = 62; 98.4%), assuming non-psychotropic drugs (N = 37; 58.7%), and died in outside hospital spaces (N = 54; 85.7%).

CONCLUSIONS

A fuller characterization of suicide among hospitalized inpatients requires systematic and computerized data gathering that provides for specific information. Indeed, this could be valuable for inpatient suicide prevention strategies as well as institutional policies.

Posttraumatic stress disorder and risk of suicidal behavior: A systematic review and meta-analysis

INTRODUCTION

This study conducted a systematic review and meta-analysis of the association between posttraumatic stress disorder (PTSD) and (i) death by suicide, (ii) attempted suicide (AS), and (iii) suicidal ideation (SI).

METHODS

The systematic review identified seven studies on PTSD and suicide, 33 studies for AS, and 20 studies for SI. A series of stratified meta-analyses were conducted to estimate pooled effects, in addition to meta-regression to investigate sources of heterogeneity.

RESULTS

A higher relative risk of suicide was evident among those diagnosed with PTSD (RR = 2.09 [95% confidence interval (CI): 1.11-3.94]), with strongest associations among combat veterans (RR = 3.97, 95% CI 2.22-7.10). A lower relative risk of suicide among those with PTSD and co-morbid psychiatric conditions was evident (RR = 0.74, 95% CI 0.63-0.86). A strong association between PTSD and attempted suicide (RR = 4.05, 95% CI 3.14-5.23) and suicidal ideation (RR = 2.91, 95% CI 2.22-3.82) was also found, with a consistently strong association among those with co-morbid psychiatric conditions and non-clinical cohorts.

CONCLUSION

This review found a strong association between PTSD and death by suicide, attempted suicide, and suicidal ideation, and also suicide among veteran populations. Early identification and treatment of PTSD across both clinical and non-clinical cohorts should be a priority for suicide prevention.

Benztropine and suicide attempts and intentional self-harm

BACKGROUND

This large-scale pharmacoepidemiologic study was conducted to confirm a previous signal for decreased risk of suicide attempt following prescription fills for benztropine.

METHODS

We used a within-person exposure-only cohort design to study the dynamic association between benztropine prescription fills over a 12-month period and suicidal events (suicide attempts and intentional self-harm) in 62,493 patients with private health insurance (MarketScan - MS) who filled a new benztropine prescription between 2011 and 2019. A discrete-time survival analysis was used to analyze the data, adjusting for age, sex, diagnoses related to suicidal behavior, Parkinson's disease, medical comorbidities, history of suicide attempts, concomitant CNS medications, and time-varying antipsychotic use.

RESULTS

Overall, there were 486 suicidal events (0.8%) following the index end-date of the one-year baseline period. Benztropine use was associated with fewer suicidal events (HR=0.63, 95% CI = 0.50, 0.80). Patients treated with antipsychotics and benztropine had a similar reduction in suicidal events as patients treated with benztropine alone in both within-subject and between-subject analyses. Similar associations were found for patients with bipolar disorder or schizophrenia, and those treated with newer versus older generation antipsychotics. Dose-response and duration response relationships were found, with an overall 6% reduction in suicidal events per 1 mg equivalent dosage per month, that was similar in those treated and those not treated with antipsychotics.

INTERPRETATIONS

Benztropine was found to lower suicidal event rates, comparably in those receiving or not receiving antipsychotic medications, regardless of the presence of major psychiatric disorders. This observation warrants testing in a randomized clinical trial.

Bibliometric analysis of post-traumatic stress disorder in forensic medicine: Research trends, hot spots, and prospects

Background

Post-traumatic stress disorder (PTSD) has various risk factors, complex pathogenesis, and diverse symptoms, and is often comorbid with other injuries and diseases, making forensic diagnosis difficult.

Methods

To explore the current research status and trends of PTSD, we used the Web of Science Core Collection databases to screen PTSD-related literature published between 2010 and 2021 and CiteSpace to perform bibliometric analysis.

Results

In recent years, PTSD-related research has grown steadily. The countries and institutions with the most research results were the United States and England, and King's College London and Boston University, respectively. Publications were identified from 2,821 different journals, including 13 forensic-related journals, but the journal distribution was relatively scattered and there was a lack of professional core journals. Keyword co-occurrence and clustering identified many hot topics; "rat model," "mental health," and "satisfaction" were the topics most likely to have a clear effect on future research. Analysis extracted nine turning points from the literature that suggested that neural network centers, the hypothalamic-pituitary-adrenal axis, and biomarkers were new research directions. It was found that COVID-19 can cause severe psychological stress and induce PTSD, but the relationship needs further study. The literature on stress response areas and biomarkers has gradually increased over time, but specific systemic neural brain circuits and biomarkers remain to be determined.

Conclusion

There is a need to expand the collection of different types of biological tissue samples from patients with different backgrounds, screen PTSD biomarkers and molecular targets using multi-omics and molecular biology techniques, and establish PTSD-related molecular networks. This may promote a systematic understanding of the abnormal activation of neural circuits in patients with PTSD and help to establish a personalized, accurate, and objective forensic diagnostic standard.

Factors associated with the time to transition from suicidal ideation to suicide plans and attempts in the Australian general population

BACKGROUND

Suicide plans and attempts rarely occur without prior suicidal ideation but are hard to predict. Early intervention efforts need to focus on subgroups of the population who are more likely to transition from ideation to suicidal plans and attempts. The current study utilised data from a large nationally representative sample to investigate the time taken to transition and the demographic and mental health correlates of transitioning to suicidal plans and attempts among those with suicidal ideation.

METHODS

Data were from 1237 Australians aged 16-85 years who reported suicidal thoughts at some point in their life. Discrete time survival analysis was used to retrospectively examine the time in years and correlates of transitioning from suicidal ideation to suicide plans and suicide attempt.

RESULTS

The majority of those who transitioned to suicide plans or attempts typically did so within 2 years of first experiencing suicidal ideation. Several factors were independently associated with increased speed to transition, including alcohol use disorder, drug use disorder, major depressive episode, obsessive compulsive disorder, sexual minority status, and non-urban location. Older age, being male, older age of first ideation and greater family support were associated with a slower transition.

CONCLUSION

The current study suggests that pre-existing mental or substance use disorders, particularly drug use disorder, as well as sexual minority status, sex and greater family support play an important role in the transition from suicidal ideation to plans or attempts. These results highlight the potential importance of suicide prevention programs that aim to improve social connectedness.

The Change of Suicidal Ideation Over a 12-Week Naturalistic Treatment of Depression: Comparison Between Young People and Older Adults

OBJECTIVE

We investigated the differences in suicidality between young people and older adults with depression over the course of 12-week naturalistic treatment with antidepressants.

METHODS

A total of 565 patients who had moderate to severe depression (Hamilton Depression Rating Scale [HAM-D] score ≥14) and significant suicidal ideation (Beck Scale for Suicide Ideation [SSI-B] score ≥6) were recruited from 18 hospitals. Participants were classified into two groups: the younger group (13-24 years of age, n=82) and the older group (≥25 years of age, n=483). Total scores over time on the SSI-B, HAM-D, and Hamilton Anxiety Rating Scale (HAM-A) were assessed and compared between the two groups.

RESULTS

At baseline, the younger group had lower HAM-D scores (21.0 vs. 22.2; p=0.028) but higher SSI-B scores (19.4 vs. 15.6; p<0.001) compared with the older group. The overall 12-week proportion of patients with resolved suicidality was 44.1% in the younger group and 69.2% in the older group. Although the improvement in the HAM-D and HAM-A scores did not differ between the groups, suicidal ideation in the younger group remained more severe than in the older group throughout the treatment. The ratio of the subjects who achieved HAM-D remission or response but did not achieve SSI-B remission was significantly higher in the younger group than in the older group.

CONCLUSION

These data suggest that in depressed youths, suicide risk is a serious concern throughout the course of depression even when favorable treatment outcomes are obtained.

The shared genetic architecture of suicidal behaviour and psychiatric disorders: A genomic structural equation modelling study

Background: Suicidal behaviour (SB) refers to behaviours, ranging from non-fatal suicidal behaviour, such as suicidal ideation and attempt, to completed suicide. Despite recent advancements in genomic technology and statistical methods, it is unclear to what extent the spectrum of suicidal behaviour is explained by shared genetic aetiology. Methods: We identified nine genome-wide association statistics of suicidal behaviour (sample sizes, n, ranging from 62,648 to 125,844), ten psychiatric traits [n up to 386,533] and collectively, nine summary datasets of anthropometric, behavioural and socioeconomic-related traits [n ranging from 58,610 to 941,280]. We calculated the genetic correlation among these traits and modelled this using genomic structural equation modelling, identified shared biological processes and pathways between suicidal behaviour and psychiatric disorders and evaluated potential causal associations using Mendelian randomisation. Results: Among populations of European ancestry, we observed strong positive genetic correlations between suicide ideation, attempt and self-harm (rg range, 0.71-1.09) and moderate to strong genetic correlations between suicidal behaviour traits and a range of psychiatric disorders, most notably, major depression disorder (rg = 0.86, p = 1.62 × 10^-36). Multivariate analysis revealed a common factor structure for suicidal behaviour traits, major depression, attention deficit hyperactivity disorder (ADHD) and alcohol use disorder. The derived common factor explained 38.7% of the shared variance across the traits. We identified 2,951 genes and 98 sub-network hub genes associated with the common factor, including pathways associated with developmental biology, signal transduction and RNA degradation. We found suggestive evidence for the protective effects of higher household income level on suicide attempt [OR = 0.55 (0.44-0.70), p = 1.29 × 10^-5] and while further investigation is needed, a nominal significant effect of smoking on suicide attempt [OR = 1.24 (1.04-1.44), p = 0.026]. Conclusion: Our findings provide evidence of shared aetiology between suicidal behaviour and psychiatric disorders and indicate potential common molecular mechanisms contributing to the overlapping pathophysiology. These findings provide a better understanding of the complex genetic architecture of suicidal behaviour and have implications for the prevention and treatment of suicidal behaviour.

Use of Telehealth to Address Depression and Anxiety in Low-income US Populations: A Narrative Review

Symptoms of anxiety and depressive disorders have been increasing substantially among adults in the United States (US) during the COVID-19 pandemic, particularly for low-income populations. Under-resourced communities have difficulties accessing optimal treatment for anxiety and depression due to costs as well as the result of limited access to health care providers. Telehealth has been growing as a digital strategy to treat anxiety and depression across the country but it is unclear how best to implement telehealth interventions to serve low-income populations. A narrative review was conducted to evaluate the role of telehealth in addressing anxiety and depression in low-income groups in the US. A PubMed database search identified a total of 14 studies published from 2012 to 2022 on telehealth interventions that focused on strengthening access to therapy, coordination of care, and medication and treatment adherence. Our findings suggest that telehealth increases patient engagement through virtual therapy and the use of primarily telephone communication to treat and monitor anxiety and depression. Telehealth seems to be a promising approach to improving anxiety and depressive symptoms but socioeconomic and technological barriers to accessing mental health services are substantial for low-income US populations.

Violence - suicide and suicidal ideation as sequelae of trauma in substance use disorder inpatients

Experience with psychological trauma is overrepresented among substance use disorder (SUD) patients. SUDs may also be a risk factor for violent behaviors, suicidal ideation and suicide. This study proposes a link between these phenomena. Based on data from the EuropASI clinical interview of 137 SUD inpatients we computed a composite variable of trauma experience from being abused. We report descriptive data and cross tabulated problems controlling violent behavior, suicidal ideation or suicide attempts variables with trauma experience. Hypothesizing an association between experienced trauma and the outcome variables. We also examined the correlation between three outcome variables in inpatients. Our data suggested high incidents of experienced psychological trauma in the sample (66.7%). Chi-square tests suggested a significant difference in controlling violent behavior, suicidal ideation and suicide attempts, dependent on trauma experience. Spearman Roh correlations suggested asscociations between suicdal ideation and suicide attempts, and suicdal ideation and problems controlling violent behavior, but not with suicide attempts. Our data suggests that past trauma is a risk factor for violent and suicidal behaviors in the SUD population. Based on our findings we propose that former trauma should be considered in risk assessments and help guide treatment interventions.

Associations between anxiety, depression, and risk of suicidal behaviors in Chinese medical college students

Background

Previous studies have established a strong association between depression and suicidal behaviors, yet the relationship between anxiety and suicidal behaviors remains unclear. This study examines whether anxiety and depression are independent risk factors for suicidal behaviors in medical college students, and further, whether anxiety may increase the greater risk of suicidal behaviors (SB) in participants with depression.

Methods

This cross-sectional study was conducted among 4,882 medical students. Demographic information, anxiety, and depression data were collected using online questionnaires or through a widely used social media app named WeChat.

Results

Anxiety and depression were independent risk factors for suicidal behaviors, and levels of risk correlated positively with the severity of both anxiety and depressive symptoms. A dose-response relationship was identified between the severity of anxiety and the risk of SB, as well as the severity of depression and SB. Furthermore, anxiety increased the risk of suicidal behaviors in participants with depression, with a dose-response relationship between the severity of anxiety symptoms and the risk of SB.

Conclusion

The findings highlight the importance of screening for anxiety and depressive symptoms in medical college students, as well as reducing anxiety in addition to depressive symptoms in treatment. This study provides valuable data as a reference for clinicians for suicide risk assessments.

Inflammation, cognitive dysfunction, and suicidal ideation among patients with major depression

BACKGROUND

Dysregulated proinflammatory cytokines have been shown to be associated with suicidal behavior. Cognitive deficits in working memory and inhibitory control have been demonstrated in depressed patients and people with suicidal ideation (SI). However, the association between proinflammatory cytokines, SI, and cognitive deficits in patients with major depressive disorder (MDD) remains unclear.

METHODS

A total of 77 patients with MDD and age-/sex-matched 60 healthy individuals were recruited. MDD patients were divided into two groups: with SI (n = 36) and no SI (n = 41). SI was defined by a score of ≥2 in item 3 of the 17-item Hamilton Rating Scale for Depression. Levels of proinflammatory cytokines, including soluble interleukin-6 receptor, soluble tumor necrosis factor-α receptor type 1, and C-reactive protein (CRP), were measured, and cognitive function was assessed using 2-back task and Go/No-Go task.

RESULTS

Patients with SI had higher levels of CRP than those without SI and controls (P = .007). CRP was positively associated with SI (β = 0.21, P = .037), independent of cognitive function and depressive symptoms. Furthermore, SI was associated with cognitive deficits in working memory and inhibitory control after adjusting for confounding factors (P < .05).

CONCLUSION

Our findings suggest that higher levels of serum CRP and deficits in working memory and inhibitory control may be associated with higher SI among patients with MDD.

Diminished body trust uniquely predicts suicidal ideation and nonsuicidal self-injury among people with recent self-injurious thoughts and behaviors

INTRODUCTION

Self-injurious thoughts and behaviors (SITBs) are difficult to predict, and novel risk factors must be identified. While diminished interoception is associated with SITBs cross-sectionally, the current study assesses whether multiple measures of interoception predict future SITBs.

METHODS

Adults (N = 43) with recent SITBs completed assessments of interoception during a baseline visit. Participants then completed biweekly assessments for 6 months in which they reported the presence and severity/frequency of suicidal ideation and nonsuicidal self-injury (NSSI).

RESULTS

Multilevel models were performed, where baseline interoceptive measures predicted presence and severity/frequency of suicidal ideation and NSSI at follow-up. The Multidimensional Assessment of Interoceptive Awareness (MAIA) Trusting subscale was the only significant predictor of the presence/severity of suicidal ideation. The MAIA Trusting, Emotional Awareness, and Body Listening subscales significantly predicted the presence of NSSI. The MAIA Emotional Awareness subscale and the Body Perception Questionnaire significantly predicted NSSI frequency.

DISCUSSION

Diminished body trust predicted both suicidal ideation and NSSI, indicating a potential shared risk pathway. However, two interoception measures (Body Listening subscale and Body Perception Questionnaire) were associated with NSSI only, indicating potentially unique risk pathways. Given the differential associations between interoception measures and SITBs, results highlight the importance of clearly defining how interoception is measured.

Men’s anxiety, why it matters, and what is needed to limit its risk for male suicide

Anxiety disorders are the most prevalent mental health disorder experienced by men. If left untreated, anxiety is predictive of psychiatric disorders including depression and associated suicide risk. Despite the prevalence and impact of men’s anxiety, it remains largely overlooked in the field of men’s mental health. Globally, men are reported to have lower rates of anxiety disorders compared to women; however, these sex-differences do not reflect the complexity and nuance of men’s experiences. There is early evidence to suggest a male-type anxiety phenotype which may go undetected with generic diagnostic classifications. Masculine norms (i.e., stoicism, toughness, invulnerability) appear to be central to men’s experiences and expressions of anxiety as well as men’s help-seeking and coping behaviours. This is particularly concerning given anxiety increases men’s risk of physical and psychological comorbidities and suicide risk. The effective assessment, detection and treatment of men’s anxiety is therefore critical to improve mental health outcomes across the male lifespan. We propose three key recommendations for the field of men’s anxiety: (i) to develop a theoretical model surrounding men’s experiences of anxiety, (ii) broaden mental health resources, interventions and suicide prevention strategies to encompass men’s gendered experiences of anxiety (e.g., sentiments of shame, physical symptom manifestation), and (iii) utilise informal supports (i.e., friends and family) as an avenue of intervention to improve men’s anxiety outcomes. Without a substantial research agenda in men’s anxiety, we will fail to recognise and respond to men’s gendered experiences of anxiety and ultimately fail to reduce male suicides.

Associations of suicide risk with emotional reactivity, dysregulation, and eating disorder treatment outcomes

INTRODUCTION

Emotional processes play a role in both suicide risk and eating disorders (EDs), which are often comorbid. However, limited research has explored how emotional processes relate to suicide risk in EDs and the prognostic value of suicide risk for ED treatment. Thus, the current study examined associations between emotion dysregulation and reactivity with suicide risk in patients with EDs, and determined if suicide risk predicts ED treatment outcomes.

METHODS

Participants (n = 201) were adults in an ED partial hospitalization program who completed measures at admission, 1-month post-admission, and discharge.

RESULTS

When controlling for depressive symptoms, limited access to adaptive emotion regulation strategies, difficulties engaging in goal-oriented behaviors, and engaging in impulsive behavior when experiencing negative emotions (i.e., emotion dysregulation) were associated with suicide attempt frequency. Depressive symptoms were associated with suicide risk severity, while emotion dysregulation and reactivity were not. Importantly, patients with elevated suicide risk at admission improved comparably to other risk categories across treatment, despite presenting with greater ED symptoms at admission.

CONCLUSION

Emotion dysregulation and depression are salient factors when examining suicide risk in patients with EDs. Suicide risk and attempt history may not negatively impact ED treatment outcomes when using emotion-focused treatment.

Age at Menopause and Suicidal Ideation in Menopausal Women: A Study of Korea National Health and Nutrition Examination Survey Data

BACKGROUND

Although menopause is considered a risk factor for depression, no association has been established between the risk of suicidal ideation and age at menopause. This study aimed to evaluate the association between age at menopause and suicidal ideation in middle-aged menopausal Korean women.

METHODS

This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (2013-2018). Women aged 40-65 years were divided into the following three categories: primary ovarian insufficiency (POI), early menopause, and menopause, according to age at natural menopause (< 40, 40-45, and > 45 years, respectively). Depressive symptoms were assessed using the Patient Health Questionnaire-9 (PHQ-9).

RESULTS

Among 2,232 menopausal women, 25 (1.1%) experienced POI and 114 (5.1%) experienced early menopause. The PHQ-9 items that pertained to low self-esteem and suicidal ideation scored higher in women with POI than in those who experienced menopause after 45 years of age. The prevalence of suicidal ideation differed significantly according to age at menopause (POI, 30.0%; early menopause, 12.7%; menopause, 8.0%; P = 0.016). Logistic regression analysis revealed that POI was significantly associated with suicidal ideation after the adjustment for age, body mass index, and education, household income, and walking levels (odds ratio, 4.2; 95% confidence interval, 1.0-17.7).

CONCLUSION

Korean middle-aged women with POI were more likely to have suicidal ideation than those who experienced menopause at 45 years or above, despite not being diagnosed with major depressive disorder.

Social cognitive mechanisms between psychological maltreatment and adolescent suicide ideation: Race/ethnicity and gender as moderators

Childhood psychological maltreatment is a well-studied predictor of adolescent suicide ideation, while social support is a protective factor, but little is known about social-cognitive mechanisms that may link psychological maltreatment to suicide ideation. Further, given the impact that culture, race/ethnicity, and gender can have on social relationships and suicide-related risk factors, these mechanisms may differ across demographic groups.

Objective

The current study examined whether psychological maltreatment predicts suicide ideation through self-perception of social competence, and whether this relationship differs depending on race/ethnicity and gender.

Method

We analyzed a racially diverse, longitudinal sample of adolescents at risk for maltreatment (N = 765). Self-report measures of lifetime maltreatment were completed at age 12 and combined with data from Child Protective Services. Youth also completed measures of perceived social competence at age 12. Indicators of suicide ideation were taken at ages 8, 12, 16, and 18.

Results

Perceived social competence scores differed significantly between children who were psychologically maltreated and those who were not, but these differences were nonsignificant for physical and sexual abuse. Self-perception of social competence fully mediated the relationship between childhood psychological maltreatment and suicide ideation for White girls and boys.

Conclusions

Our findings suggest that poor perceived social competence is uniquely associated with psychological maltreatment, and White adolescents may develop suicide ideation through specific mechanisms involving social cognition. Certain youth may benefit from interventions improving social cognitions and promoting healthy relationships to prevent suicide ideation during adolescence.

The effects of peer bullying and poverty on suicidality in Chinese left behind adolescents: The mediating role of psychotic-like experiences

AIM

This study investigated the influence of childhood adversity, such as peer bullying and socioeconomic status, on the suicidal behaviour of left-behind Chinese adolescents to determine whether psychotic-like experiences (PLEs) mediated the associations between these childhood adversities and suicidality; suicidal ideation (serious thoughts about taking one's own life), suicide plans, and suicide attempts.

METHODS

A representative group of rural adolescents (n = 3346) was recruited from 16 rural high schools in China. Suicidality was assessed using the suicide module from the Mini International Neuropsychiatric Interview Kid. Participants also completed questionnaires on bullying, socioeconomic status, left-behind characteristics, and PLEs. Structural equation modelling was then employed to explore the relationships between these variables.

RESULTS

Peer bullying, poverty, and left-behind status were all found to significantly increase adolescent suicide risk, the relationships between which were mediated by PLEs. Peer bullying was found to play the most significant role in the PLEs and suicidality, with the risk of suicide increasing with the length of time a child had been left behind.

CONCLUSION

Adverse life events can lead to a high risk of PLEs, which in turn can increase the risk of suicide. These results could assist in identifying individuals at risk of suicidality and the design of appropriate interventions. The results also highlighted the role PLEs play in suicidality and highlighted the need for further research in this area.

Depressive symptoms in older adults with and without a history of incarceration: A matched pairs comparison

OBJECTIVES

Previous research has found that many incarcerated individuals have mental health conditions and that incarcerated women may be at elevated risk. These individuals have been shown to experience mental health concerns shortly after their release, but little is known about their mental health later in life. This study compared depressive symptoms in older adults with and without a history of incarceration and examined the impact of gender on this relationship.

METHOD

Data from 160 pairs of adults aged 65 or older (82.5% male, mean age = 73.4 years) who participated in the 2012 wave of the Health and Retirement Study (HRS) was utilized. Older adults with a history of incarceration were matched to those without based on age, gender, race, and education level. Depressive symptoms (CES-D) of older adults with and without a history of incarceration were compared using a repeated-measures ANOVA.

RESULTS

The main effect of incarceration history (p=.001, partial eta²=.07) and the interaction between incarceration history and gender (p=.01, partial eta²=.04) were significant. Follow-up analyses revealed that the difference between depressive symptoms for older women with and without a history of incarceration was significant (p=.02, d = 0.69), whereas the difference for older men was not significant (p=.19, d = 0.16).

CONCLUSIONS

Findings suggest older adults with a history of incarceration report more depressive symptoms than those without and that the effect is seen among older women. Negative effects of incarceration on mental health may therefore persist into later life, highlighting the importance of pre- and post-release mental health services.

Association Between Folic Acid Prescription Fills and Suicide Attempts and Intentional Self-harm Among Privately Insured US Adults

Importance

Suicide is a leading cause of death in the United States, having increased more than 30% from 2000 to 2018. An inexpensive, safe, widely available treatment for preventing suicidal behavior could reverse this trend.

Objective

To confirm a previous signal for decreased risk of suicide attempt following prescription fills for folic acid in a national pharmacoepidemiologic study of patients treated with folic acid.

Design, Setting, and Participants

A within-person exposure-only cohort design was used to study the dynamic association between folic acid (vitamin B9) prescription fills over a 24-month period and suicide attempts and intentional self-harm. Data were collected from a pharmacoepidemiologic database of US medical claims (MarketScan) for patients with private health insurance who filled a folic acid prescription between 2012 and 2017. The same analysis was repeated with a control supplement (cyanocobalamin, vitamin B12). Data were analyzed from August 2021 to June 2022.

Exposure

Folic acid prescription fills.

Main Outcome and Measure

Suicide attempt or intentional self-harm resulting in an outpatient visit or inpatient admission as identified by codes from the International Statistical Classification of Diseases, Ninth and Tenth Revisions, Clinical Modification.

Results

Data on 866 586 patients were collected; 704 514 (81.30%) were female, and 90 296 (10.42%) were 60 years and older. Overall, there were 261 suicidal events during months covered by a folic acid prescription (5 521 597 person-months) for a rate of 4.73 per 100 000 person-months, compared with 895 suicidal events during months without folic acid (8 432 340) for a rate of 10.61 per 100 000 person-months. Adjusting for age and sex, diagnoses related to suicidal behavior, diagnoses related to folic acid deficiency, folate-reducing medications, history of folate-reducing medications, and history of suicidal events, the hazard ratio (HR) for folic acid for suicide events was 0.56 (95% CI, 0.48-0.65), with similar results for the modal dosage of 1 mg of folic acid per day (HR, 0.57; 95% CI, 0.48-0.69) and women of childbearing age (HR, 0.60; 95% CI, 0.50-0.73). A duration-response analysis (1-mg dosage) revealed a 5% decrease in suicidal events per month of additional treatment (HR, 0.95; 95% CI, 0.93-0.97). The same analysis for the negative control, cyanocobalamin, found no association with suicide attempt (HR, 1.01; 95% CI, 0.80-1.27).

Conclusions and Relevance

This large-scale pharmacoepidemiologic study of folic acid found a beneficial association in terms of lower rates of suicide attempts. The results warrant the conduct of a randomized clinical trial with suicidal ideation and behavior as outcomes of interest. If confirmed, folic acid may be a safe, inexpensive, and widely available treatment for suicidal ideation and behavior.

Potential paths to suicidal ideation and suicide attempts among high-risk women

Although men are more likely to die by suicide, women experience a greater and more rapidly increasing rate of suicidal ideation (SI) and are 3 times more likely to attempt suicide than men. Despite this increased risk, little is known about factors that contribute to SI or suicide attempts (SA) among women. We examined factors associated with SI and SA among women and identified mood-related symptoms that differentiate women who reported attempting suicide from those who did not. Women at elevated risk for depression from across the U.S. (N = 3372; age 18 to 90) completed a survey regarding depression, anxiety, sociodemographic and reproductive status, behavioral/mental health history, and exposure to adversity. Structural equation modeling and logistic regression were used to analyze the data. Variables with the most significant relationships to SI were severity of depression (OR = 5.2, p = 0.000) and perceived stress (OR = 1.18, p = 0.000) while frequency of suicidal thoughts (OR = 3.3, p = 0.000), family history of a depression diagnosis (OR = 1.6, p = 0.000) and exposure to violence (OR = 1.9, p = 0.000) had the strongest association with SA. Childhood abuse/trauma was associated with SA (OR = 1.13, p = 0.000) but not SI. 'Feeling bad about themselves, a failure, or having let themselves or their family down' was the symptom that most clearly differentiated women who attempted suicide from women who reported suicidal ideation but no SA. The salience of childhood abuse and domestic/community violence to women's risk for a suicide attempt reinforces previous findings that these adversities may differentiate suicide risk for women versus men. Continued research is essential to understand varied paths that may lead to suicidal behavior among women, some which appear unrelated to the frequency or intensity of their suicidal thoughts.

Suicide risk and mental health in the general population of French Polynesia

OBJECTIVE

There are no reports on the burden of suicidal ideation and suicide attempts in the general population of French Polynesia (FP). We aimed to improve suicide prevention and mental health care by assessing the prevalence of suicide risk and major mental health disorders and care among adults in FP.

METHODS

We conducted the Mental Health in General Population Survey in FP during 2015 to 2017. Participants were selected using the quota method to obtain a representative sample of the general population. Suicide risk and psychiatric diagnoses were assessed using the Mini International Neuropsychiatric Interview.

RESULTS

We included 968 people aged 18 years or older. The prevalence of current suicidal ideation (13.1%) and current (2.6%) and lifetime suicide attempts (18.6%), as well as mental health disorders (42.8%), was high in FP. A notable proportion of participants with these conditions did not seek medical assistance.

CONCLUSION

A high prevalence of suicide risk and mental health disorders was found in the general population of FP. Suicide prevention and mental health plans are needed in FP that include better access to primary care for the diagnosis and treatment of mental health disorders. Further research is needed to clarify cultural risk and protective factors.

Suicidal behavior and associated factors among prisoners at Dessie town correctional institution, Dessie, Ethiopia

BACKGROUND

Suicide is a prominent cause of death among inmates worldwide, accounting for over 30% of all deaths. Several factors, including prison-related, psychiatric disorders, stressful life events, and substance use-related factors are believed to be associated with an increased risk of suicidal behavior in a correctional facility. The present study aimed to determine the prevalence and associated factors of Suicidal Behavior among prisoners at Dessie town correctional institution, Ethiopia.

METHODS

From February 16 to March 5, 2020, a cross-sectional survey was conducted among 288 inmates at the Dessie Town Correctional Center. A systematic random sampling technique was used to select study participants during the study period. Data was collected through face-to-face interview methods using Suicidal Behavior Revised (SBQ-R). The collected data were coded, entered into Epi-data data version 3.1, and analyzed by SPSS Version 26. Binary logistic regression was carried out to identify independent predictors of suicidal behavior at a 95% confidence level. Variables at a p-value < 0.05 with 95% CI were declared statistically significant.

RESULTS

The prevalence of Suicidal behavior among prisoners was found to be 25.3% [(95% CI: 20.5, 30.6)]. This study showed that being female [AOR = 5.14;95% CI (1.62,16.29)], depression [AOR = 4.97;95%CI (2.53,9.77)], anxiety [AOR = 3.14; 95%CI (1.59,6.22)], experienced stressful life events [AOR = 5.11; 95%CI (2.24, 11.65)], and ever substance use [AOR = 2.83; 95%CI (1.41, 5.59)] were variables significantly associated with suicidal behavior among prisoners in Dessie town correctional institution.

CONCLUSION AND RECOMMENDATIONS

In this study, suicidal behavior was highly prevalent among prisoners compared to the general population. Being female, depression, anxiety, stress full life events, and substance use were variables that are independent predictors of suicidal behavior. This study recommends that the institution needs to deliver an appropriate psychiatric facility to diagnose and treat prisoners with suicidal behavior. Also, special attention should be given to early screening and treatment of prisoners through prison health services, which is the most critical prevention strategy of suicide in prisoners.

Associations between traumatic event experiences, psychiatric disorders, and suicidal behavior in the general population of Afghanistan: findings from Afghan National Mental Health Survey

Background

The role of traumatic event exposure and psychiatric disorders as central risk factors for suicidal behavior has been established, but there are limited data in high conflict regions with significant trauma exposures such as Afghanistan.

Methods

A nationally representative, cross-sectional survey was conducted through systematic stratified random sampling in 8 regions of Afghanistan in 2017 (N = 4474). Well-validated instruments were used to establish trauma exposure, psychiatric disorders. Death preference, suicidal ideation, plan, and attempts were assessed.

Results

In the total sample, 2.2% reported suicidal ideation in the past 12 months, and 7.1% of respondents reported that they had suicidal ideation at some point in their lives; 3.4% reported a suicide attempt. Women were at higher risk than men. All traumatic event exposures were strongly associated with suicidal behavior. Respondents who reported experiencing sexual violence were 4.4 times more likely to report lifetime suicide attempts (95% CI 2.3–8.4) and 5.8 times more likely to report past 12-month suicidal ideation (95% CI 2.7–12.4). Associations were strong and significant for all psychiatric disorders related to suicidal behavior. Respondents who met criteria for major depressive episodes (OR = 7.48; 95% CI 4.40–12.72), generalized anxiety disorder (OR = 6.61; 95% CI 3.54–12.33), and PTSD (OR = 7.26; 95% CI 4.21–12.51) had the highest risk of past 12-month suicidal ideation.

Conclusion

Traumatic event exposures and psychiatric disorders increase risk of suicidal behavior in the Afghan general population; women are at high risk. Interventions to reduce trauma exposure, including expansion of a mental health workforce in the region, are critically important.

Prediction of suicide attempts in a prospective cohort study with a nationally representative sample of the US population

BACKGROUND

There is still little knowledge of objective suicide risk stratification.

METHODS

This study aims to develop models using machine-learning approaches to predict suicide attempt (1) among survey participants in a nationally representative sample and (2) among participants with lifetime major depressive episodes. We used a cohort called the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) that was conducted in two waves and included a nationally representative sample of the adult population in the United States. Wave 1 involved 43 093 respondents and wave 2 involved 34 653 completed face-to-face reinterviews with wave 1 participants. Predictor variables included clinical, stressful life events, and sociodemographic variables from wave 1; outcome included suicide attempt between wave 1 and wave 2.

RESULTS

The model built with elastic net regularization distinguished individuals who had attempted suicide from those who had not with an area under the ROC curve (AUC) of 0.89, balanced accuracy 81.86%, specificity 89.22%, and sensitivity 74.51% for the general population. For participants with lifetime major depressive episodes, AUC was 0.89, balanced accuracy 81.64%, specificity 85.86%, and sensitivity 77.42%. The most important predictor variables were a diagnosis of borderline personality disorder, post-traumatic stress disorder, and being of Asian descent for the model in all participants; and previous suicide attempt, borderline personality disorder, and overnight stay in hospital because of depressive symptoms for the model in participants with lifetime major depressive episodes. Random forest and artificial neural networks had similar performance.

CONCLUSIONS

Risk for suicide attempt can be estimated with high accuracy.

Ethical and methodological challenges slowing progress in primary care-based suicide prevention: Illustrations from a randomized controlled trial and guidance for future research

INTRODUCTION

Despite the pressing need for primary care-based suicide prevention initiatives and growing acknowledgement of recruitment difficulties and Institutional Review Board (IRB) challenges in suicide research, we are aware of no illustrative examples describing how IRB decisions in the design of a primary care trial can compound recruitment challenges.

METHODS

The CDC-funded trial (NCT02986113) of Men and Providers Preventing Suicide aimed to examine the effects of a tailored computer program encourage men with suicidal thoughts (n = 304, ages 35-64) to discuss suicide with a primary care clinician and accept treatment. Before a visit, participants viewed MAPS or a non-tailored control video. Post-visit, both arms were offered telephone collaborative care, as mandated by the institutional review board (IRB). We previously showed that exposure to MAPs led to improvements in communication about suicide in a primary care visit. In this paper, we report data on the study's primary outcome, suicide preparatory behaviors.

RESULTS

After screening nearly 4100 men, 48 enrolled. Recruitment challenges, which were exacerabted by an IRB mandate narrowing post-intervention patient management differences between trial arms, limited detection of the effects of MAPS on suicide preparatory behaviors.

CONCLUSIONS

While primary care settings are key sites for suicide prevention trials, issues such as recruitment difficulties and overly restrictive IRB requirements may limit their utility. Methodological innovation to improve recruitment and ethical guidance to inform IRB decision-making are needed.

Genetics and epigenetics of self-injurious thoughts and behaviors: Systematic review of the suicide literature and methodological considerations

Suicide is a multifaceted and poorly understood clinical outcome, and there is an urgent need to advance research on its phenomenology and etiology. Epidemiological studies have demonstrated that suicidal behavior is heritable, suggesting that genetic and epigenetic information may serve as biomarkers for suicide risk. Here we systematically review the literature on genetic and epigenetic alterations observed in phenotypes across the full range of self-injurious thoughts and behaviors (SITB). We included 577 studies focused on genome-wide and epigenome-wide associations, candidate genes (SNP and methylation), noncoding RNAs, and histones. Convergence of specific genes is limited across units of analysis, although pathway-based analyses do indicate nervous system development and function and immunity/inflammation as potential underlying mechanisms of SITB. We provide suggestions for future work on the genetic and epigenetic correlates of SITB with a specific focus on measurement issues.

Child Sexual Abuse and Suicide: Essentials for the Forensic Nurse

Sexual abuse can result in significant negative sequelae for victims. One particularly harmful consequence is suicidal ideation, which can lead to suicide attempts and even death. It is essential to screen children and adolescents for suicidal ideation when providing medical forensic care after disclosure of acute or nonacute sexual abuse/assault. Forensic nurses must feel confident in their abilities to assess suicide risk and provide appropriate intervention and referrals. A thorough understanding of the relationship between sexual abuse and suicidal ideation and behaviors can assist the forensic nurse in the development of practice behaviors to better identify, intervene, and prevent suicidal ideation and behaviors among youth experiencing sexual abuse.

The Applicability of Linehan Risk Assessment Scale: a Cross-Sectional Study from Alexandria Poison Centre, Egypt, During the COVID-19 Pandemic

Background/Objective

Suicide is a critical health problem that is significantly rising during the COVID-19 pandemic worldwide, yet it is still under-reported in Egypt. To date, a deficiency of a reliable scale to probe the risk factors underlying suicide liability among patients with deliberate self-poisoning. The study’s objective was to offer a snapshot of the pattern of self- poisoning in Egypt during the COVID-19 pandemic.

Methods

Using the Linehan Risk Assessment and Management Protocol LRAMP, a psychological assessment was applied to evaluate vulnerable patients needing urgent psychiatric support and emphasize the influence of previous suicidal behaviors. A cross-sectional study was conducted on all patients admitted to Alexandria Poison Centre with deliberate self-poisoning biosocial and poisoning data that were recorded in a specially designed sheet. All patients were interviewed for underlying risk factors and protective factors for suicidal behavior.

Results

Significant relation was recorded between previous suicidal attempts and psychiatric diseases. CNS depressant drugs and rodenticides recorded the highest frequency. The calculated score (suicide and protective factors) was higher in patients with previous suicidal attempts.

Conclusion

The study was the first to test the applicability of Linehan scale in Alexandria Poison Centre. The results are promising; however, multicenter replication of the concluded findings will be valuable.

Cancer and psychiatric diagnoses in the year preceding suicide

BACKGROUND

Patients with cancer are known to be at increased risk for suicide but little is known about the interaction between cancer and psychiatric diagnoses, another well-documented risk factor.

METHODS

Electronic medical records from nine healthcare systems participating in the Mental Health Research Network were aggregated to form a retrospective case-control study, with ICD-9 codes used to identify diagnoses in the 1 year prior to death by suicide for cases (N = 3330) or matching index date for controls (N = 297,034). Conditional logistic regression was used to assess differences in cancer and psychiatric diagnoses between cases and controls, controlling for sex and age.

RESULTS

Among patients without concurrent psychiatric diagnoses, cancer at disease sites with lower average 5-year survival rates were associated with significantly greater relative risk, while cancer disease sites with survival rates of >70% conferred no increased risk. Patients with most psychiatric diagnoses were at higher risk, however, there was no additional risk conferred to these patients by a concurrent cancer diagnosis.

CONCLUSION

We found no evidence of a synergistic effect between cancer and psychiatric diagnoses. However, cancer patients with a concurrent psychiatric illness remain at the highest relative risk for suicide, regardless of cancer disease site, due to strong independent associations between psychiatric diagnoses and suicide. For patients without a concurrent psychiatric illness, cancer disease sites associated with worse prognoses appeared to confer greater suicide risk.

Longitudinal associations among academic achievement and depressive symptoms and suicidal ideation in elementary schoolchildren: disentangling between- and within-person associations

Prior cross-sectional and unidirectional longitudinal research has investigated the associations among academic achievement, depressive symptoms, and suicidal ideation without distinguishing between-person effects from within-person effects. Our study aimed to examine the longitudinal relations among academic achievement, depressive symptoms, and suicidal ideation in a sample of elementary school children at the within-person level using cross-lagged panel models (CLPMs) and random intercept cross-lagged panel models (RI-CLPMs). Also, multiple models replicated these findings by using three measures of academic achievement (i.e., objective academic achievement, subjective academic achievement, and teacher-assigned academic achievement). A sample of 715 Chinese elementary schoolchildren completed self-report measures of subjective academic achievement, depressive symptoms, and suicidal ideation on five occasions, using 6-month intervals. Objective academic achievement data were obtained from school records and teacher-assigned academic achievement data were reported by teachers. The results showed that: (a) In CLPMs, objective academic achievement negatively predicted suicidal ideation. However, RI-CLPMs supported the negative effect of suicidal ideation on objective academic achievement. (b) The CLPMs revealed reciprocal associations between subjective and teacher-assigned academic achievement and depressive symptoms, respectively. However, RI-CLPMs only provided support for the negative effect of depressive symptoms on subjective academic achievement. (c) Both the CLPMs and the RI-CLPMs showed bidirectional relations between depressive symptoms and suicidal ideation. These findings highlight that mental health problems (e.g., depressive symptoms and suicidal ideation) serve as antecedents of academic performance and that it is beneficial to distinguish between between-person and within-person effects in research informing the development of prevention and intervention programs.

Diffusion tensor imaging studies on subjects with suicidal thoughts and behaviors: A descriptive literature review

OBJECTIVE

Globally, suicide represents the second leading cause of death in young people aged 15-29 years for both sexes, after traffic accidents. Suicide occurs not only in high-income countries, in high-income countries but it is a global phenomenon in all regions of the world and it represents a serious public health problem.

METHOD

This review was conducted on studies focused on white matter alterations in people who have attempted or thought about suicide. We searched PubMed and Scopus databases and screened references of included studies and reviewed articles for additional citations. From the initial 21 publications, we included only 12 studies that met search criteria and described the association between white matter alterations and suicide.

RESULTS

White matter alterations in suicidal behaviors were found in the prefrontal cortex, orbitofrontal cortex, internal capsule, corpus callosum, and default mode networks, which are critical cerebral areas involved in emotion processing and regulation, decision-making, executive functions, and empathy.

CONCLUSIONS

White matter alteration in cerebral areas involving high cognitive process and emotional regulation to confer a heightened vulnerability for suicidal behavior. Suicide is a complex process ranging from suicidal ideation to planning, attempting, or committing suicide. The identification of abnormalities in underlying neural circuitry may help delineate the neurobiological basis for suicide risk.

Associations between lifetime mental disorders and suicidal behaviors: findings from the Taiwan psychiatry morbidity survey

BACKGROUND

East Asia has high suicide rates but low prevalence of mental disorders. We examined the associations between prior lifetime mental disorders (mood disorders, anxiety disorders, substance use disorders, and impulse control disorders) and subsequent suicidal behaviors (suicidal ideation and attempts in the general population and suicide plans, planned attempts, and unplanned attempts in suicidal ideators) in Taiwan.

METHODS

This survey applied the World Mental Health Survey Composite International Diagnostic Interview to a population representative sample of noninstitutionalized adults between 2003 and 2005. Odds ratios (ORs) obtained using discrete-time survival analysis were used to estimate population attributable fractions (PAFs) of suicidal behaviors due to lifetime mental disorders.

RESULTS

Lifetime mental illness was a significant risk factor for subsequent suicidal behaviors (except unplanned attempts among ideators) despite the relatively low prevalence of mental disorders in people with suicidality (16.1%-35.0%). Each diagnosis increased the odds of suicidal ideation. In terms of acting on suicidal ideation, mood disorders were most strongly associated with having plans (OR = 10.0; 95% confidence interval, CI 4.3-21.1), whereas substance use disorders most strongly with either planned (OR = 27.3; 95% CI 6.3-118.5) or unplanned attempts (OR = 14.5; 95% CI 1.7-121.5). PAFs of all mental disorders on suicidality lay between 20 and 30% (except 11% of unplanned attempts among ideators). Mood, anxiety, and substance use disorders had higher PAFs than impulse control disorders.

CONCLUSIONS

In addition to mood disorders, considering anxiety and substance use disorders is essential in devising population-based suicide prevention strategies.

Childhood trauma increases vulnerability to attempt suicide in adulthood through avoidant attachment

BACKGROUND

Childhood trauma and affective disorders are known risk factors for adult suicidal behavior. Studies have shown a mediating effect of insecure attachment on the effect of childhood trauma and suicidal behavior but so far it is not clear whether this effect is related to an attachment dimension (anxiety, avoidance).

AIM

The present study sought to examine the mediating effect of attachment anxiety and avoidance on suicidal behavior.

METHODS

We analyzed data on childhood trauma, attachment style, depression severity, presence of prior suicide attempts and current suicide ideation from 96 patients diagnosed with an affective disorder. Two mediation analyses were conducted to assess the effect of childhood trauma on 1) prior suicide attempts and 2) current suicidal ideation through its effect on attachment.

RESULTS

We found that childhood trauma had a complete mediated effect on the presence of prior suicide attempts through its effect on avoidant attachment (a1b1 = 0.0120, 95%-CI [0.0031, 0.0276]). However, only emotional abuse had a direct influence on suicidal ideation (c' = 0.0273, p < 0.01) without any indirect effect of anxious or avoidant attachment.

LIMITATIONS

Variables were not assessed in a prospective way and sample size was small.

CONCLUSIONS

Our findings suggest that individuals with avoidant attachment and childhood trauma are likely to present a high suicide risk. Since avoidant attachment is associated with altered perceptions and eventual rejection of social support, we recommend to screen for attachment early and to engage patients in therapeutical approaches focusing on the client-therapist alliance.

Transdiagnostic development of internalizing psychopathology throughout the life course up to age 45: a World Mental Health Surveys report

BACKGROUND

Depressive and anxiety disorders are highly comorbid, which has been theorized to be due to an underlying internalizing vulnerability. We aimed to identify groups of participants with differing vulnerabilities by examining the course of internalizing psychopathology up to age 45.

METHODS

We used data from 24158 participants (aged 45+) in 23 population-based cross-sectional World Mental Health Surveys. Internalizing disorders were assessed with the Composite International Diagnostic Interview (CIDI). We applied latent class growth analysis (LCGA) and investigated the characteristics of identified classes using logistic or linear regression.

RESULTS

The best-fitting LCGA solution identified eight classes: a healthy class (81.9%), three childhood-onset classes with mild (3.7%), moderate (2.0%), or severe (1.1%) internalizing comorbidity, two puberty-onset classes with mild (4.0%) or moderate (1.4%) comorbidity, and two adult-onset classes with mild comorbidity (2.7% and 3.2%). The childhood-onset severe class had particularly unfavorable sociodemographic outcomes compared to the healthy class, with increased risks of being never or previously married (OR = 2.2 and 2.0, p < 0.001), not being employed (OR = 3.5, p < 0.001), and having a low/low-average income (OR = 2.2, p < 0.001). Moderate or severe (v. mild) comorbidity was associated with 12-month internalizing disorders (OR = 1.9 and 4.8, p < 0.001), disability (B = 1.1-2.3, p < 0.001), and suicidal ideation (OR = 4.2, p < 0.001 for severe comorbidity only). Adult (v. childhood) onset was associated with lower rates of 12-month internalizing disorders (OR = 0.2, p < 0.001).

CONCLUSIONS

We identified eight transdiagnostic trajectories of internalizing psychopathology. Unfavorable outcomes were concentrated in the 1% of participants with childhood onset and severe comorbidity. Early identification of this group may offer opportunities for preventive interventions.

Intensive rTMS for treatment-resistant depression patients with suicidal ideation: An open-label study

The advantages of intensive repetitive transcranial magnetic stimulation (rTMS) protocol are in the possible acute effect of the stimulation and in the possible reduction in the time required to achieve remission in depression. Here, we investigated the antidepressant effects and antisuicidal effects of a more intensive rTMS protocol for treatment-resistant depression (TRD) patients with suicidal ideation. Thirty-one outpatients were included in this study, including 22 military veterans and 9 non- militaries. The rTMS treatment consisted of 25 sessions, each session lasting 30 min (60 trains of 50 pulsations, 110 % resting motor threshold intensity) for a total of 3000 pulse. The total amount of stimulation (750,000 pulses) applied by our rTMS protocol was equivalent to that of a 5-week standard rTMS protocol. We found a significant effect of time on the 17-item Hamilton Depression Rating Scale (HAMD-17) scores and the Sheehan Disability Scale (SDS) scores. There was no difference in change in the HAMD-17 scores and SDS scores between the military veteran group and the non-military group between baseline and the week 4 assessment time point. The response rate of depression was 64.52 %, and the remission rate of depression was 51.61 % at day 5. 48.39 % and 35.48 % at week 4, respectively. All patients (100 %) met response criteria of suicidal ideation, and the remission rate was 87.09 % at day 5. The response rate was 83.87 % %, and the remission rate was 77.42 % at week 4. The accelerated high-dose rTMS treatment was well tolerated by all patients. Our intensive rTMS protocol is preliminarily safe and feasible. The TRD patients with suicidal ideation could benefit from much shorter exposure to this protocol with more efficacy in comparison with conventional rTMS protocol. In addition, intensive rTMS offers a promising treatment for military veteran populations.

Life Satisfaction and Suicidal Ideation Among Chinese College Students During the Recurrent Outbreak of COVID-19: A Moderated Mediation Model

The present study examined a moderated mediation model between life satisfaction and suicidal ideation among Chinese college students during the recurrent outbreak of COVID-19. Seven hundred and ninety college students participated in the study and completed questionnaires on life satisfaction, suicidal ideation, depression, and gratitude. Findings indicated that (1) Depression played a partial mediating role between life satisfaction and suicidal ideation. Life satisfaction was not only directly affected suicidal ideation, but also indirectly affected suicidal ideation through the mediating effect of college students' depression; (2) Gratitude played a moderating role in the effect of life satisfaction on depression, and the link between life satisfaction and suicide ideation was only significant for those with higher gratitude. This study provides practical implications for the prevention of suicidal behavior among Chinese college students during the recurrent outbreak of COVID-19.

Mediating Role of Psychological Maladjustment in Relation Between Dark Triad, Psychological Distress and Subjective Happiness of Pakistani Emerging Adults

The transition from adolescence to adulthood is fraught with challenges that might have impacts on later life and personality development. Earlier research investigated Dark Triad traits in connection to emotional problems. The current study, on the other hand, focused on investigating the mediating role of psychological maladjustment in the relation of Dark Triad traits, psychological distress, and subjective happiness in emerging adults. A sample of 546 participants aged 18–25 years (M = 21.2 years) from Pakistan have participated to complete an online survey. Standardized assessment tools were used to measure the targeted variables. Results indicated that Machiavellianism and psychopathy were positively associated with psychological distress, whereas narcissism appeared to be a non-significant predictor. Subjective happiness was positively associated with Machiavellianism and negatively associated with psychopathy. In addition, mediation analysis through Structural Equation Modeling (SEM) indicated that the Dark Triad traits (Machiavellianism and psychopathology), psychological distress, and subjective wellbeing were explained by psychological maladjustment. Implications and limitations are discussed.

Suicidal Behaviors in Women With the Hypermobile Ehlers-Danlos Syndrome

BACKGROUND

Hypermobile Ehlers-Danlos syndrome (hEDS) is the most frequent heritable disorder of the connective tissue. This is characterized by a generalized fragility of tissues leading to chronic pain, disability and high levels of psychological distress. Suicidal behaviors in those affected are not uncommon but they have not been well studied. We aimed to explore aspects of suicidality and related factors in a group of patients with hEDS.

METHOD

Thirty-five women with hEDS were included in this cross-sectional study. They were assessed with the Mini-International Neuropsychiatric Interview for Axis 1 DSM-IV mental disorders and suicidality. They also responded to self-questionnaires assessing health (pain, BMI, and diagnosis delay) and psychosocial variables (social support, physical functioning, coping strategies, personality disturbances, and resilience).

RESULTS

Eleven patients (31.4%) had attempted suicide in the past. Fifteen patients (42.9%) had some degree of suicide risk at the time of evaluation, mainly mild risk (60%). Compared with patients without a history of suicide attempt, those who had attempted suicide were younger, scored higher on personality disturbances, especially on depressive, avoidant, antisocial, and borderline trait subscores, and had an increased prevalence of lifetime major depression, mania/hypomanic episodes, and anxiety disorders (p < .05). Binary logistic regression showed that personality disturbances and anxiety disorders increase the probability of belonging to the attempters group.

CONCLUSIONS

Consistent with previous reports, these data highlight the high frequency of suicidal behaviors in hEDS patients as well as the importance to explore psychopathology in those affected in order to identify vulnerable individuals and provide specific support.HIGHLIGHTSAttempted suicide in patients with hEDS is not uncommon.Age and the presence of psychopathology are associated with suicide attempt in hEDS patients.Personality disturbances and lifetime anxiety disorders predicted suicide attempted in this sample.

A network approach can improve eating disorder conceptualization and treatment

Eating disorders are severe mental illnesses with the second highest mortality rate of all psychiatric illnesses. Eating disorders are exceedingly deadly because of their complexity. Specifically, eating disorders are highly comorbid with other psychiatric illnesses (up to 95% of individuals with an eating disorder have at least one additional psychiatric illness), have extremely heterogeneous presentations, and individuals often migrate from one specific eating disorder diagnosis to another. In this Perspective, we propose that understanding eating disorder comorbidity and heterogeneity via a network theory approach offers substantial benefits for both conceptualization and treatment. Such a conceptualization, strongly based on theory, can identify specific pathways that maintain psychiatric comorbidity, how diagnoses vary across individuals, and how specific symptoms and comorbidities maintain illness for one individual, thereby paving the way for personalized treatment.

Factor structure and validity of the Revised Suicide Crisis Inventory (SCI-2) among Indian adults

BACKGROUND

There is a dearth of cross-cultural data on the psychometric properties of the revised Suicide Crisis Inventory (SCI)- 2. Our objective was to examine the factor structure, reliability, and validity of the SCI-2 among Indian adults.

METHODS

Using an online survey method, between August 20, 2020 and January 31, 2021, an anonymous questionnaire containing general sociodemographic information and self-report measures was circulated over email and social media. Confirmatory factor analyses (CFA) of the SCI-2 was carried out. We also examined the internal consistency of the SCI-2 and tested its convergent validity against the Suicide Narrative Inventory (SNI) and the Perceived Stress Scale (PSS-10).

RESULTS

A total of 302 participants (Mean age = 43.5 ± 17.9 years, 53.6% female) were obtained. Results of the one-factor CFA indicated good model fit (χ2[1769] = 5368.75, p < 0.001, Comparative Fit Index [CFI] =0.99, Root mean square error of approximation [RMSEA] =0.08). Similarly, the five-factor CFA also exhibited strong model fit (χ2[1759] = 4215.54, p < 0.001, CFI = 1.00, RMSEA =0.07). Comparison of these models indicated that the five-factor model demonstrated superior model fit (Δχ2[10] = 278.88, p < 0.001). The SCI-2 total and subscale scores showed excellent internal consistency and good convergent validity against most domains of the SNI and PSS-10.

CONCLUSION

Among Indian adults, the SCI-2 demonstrated good psychometric properties with the proposed five-factor solution providing the best fit. These findings provide support for the SCI construct and its assessment with the SCI-2 in an Asian setting.

Factors Affecting Suicidal Thoughts in Breast Cancer Patients

Background and Objectives: Women diagnosed with breast cancer experience severe trauma. Psychological help for breast cancer patients is not sufficient because of limited professional resources. The goal of this study was to identify groups of breast cancer patients with the greatest suicidal risk, who could be the first target for psychosocial interventions. Materials and Methods: The study included 421 women with stage T1–T3/N0–N3/M0 breast cancer. We provided women with a set of questionnaires 1–2 days prior to breast surgery and one year after surgery. One hundred eighty-eight patients completed the questionnaires after one year. We used the Beck Depression Inventory Second Edition (BDI-II) item Suicidal Thoughts or Intentions for the assessment of suicidal risk. The Impact of Event Scale-Revised (IES-R) was used to measure the risk of PTSD and the Vrana–Lauterbach Traumatic Events Questionnaire-Civilian, TEQ-C (TEQ-CV) was used to measure whether patients had experienced other traumatic events in their lifetime. Results: The incidence of suicidal ideation one year after surgery increased from 4.3% to 12.8% of patients. Patients who lived in rural areas had a two times greater risk of suicidal thoughts than patients who lived in urban areas. Working patients were 2.5 times more likely to have suicidal thoughts prior to surgery. Severely traumatic events increased the chances of suicidal ideation (OR 7.72; 95% CI 1.63–36.6; p = 0.01). The symptoms of PTSD showed a threefold increase in the likelihood of suicidal ideation (OR 2.89; 95% CI 0.98–8.55; p = 0.05). Conclusions: Living in the countryside, having a history of traumatic experience, having a paid job and having symptoms of post-traumatic stress disorder influence suicidal ideation in breast cancer patients. Particular attention should be drawn to individuals with multiple risk factors.
