Suicide risk in mood disorders

General practitioners' views towards diagnosing and treating depression in five southeastern European countries

AIM

To assess and compare general practitioners' (GPs') views of diagnosing and treating depression in five southeastern European countries.

METHODS

A cross-sectional study was conducted in Albania, Bulgaria, Moldova, Romania, and Serbia. The sample included 467 GPs who completed a hard-copy self-administered questionnaire, consisting of self-assessment questions related to diagnosing and treating depression.

RESULTS

The most common barriers to managing depression in general practice reported by GPs were: patients' unwillingness to discuss depressive symptoms (92.3%); appointment time too short to take an adequate history (91.9%), barriers for prescribing appropriate treatment (90.6%); and patients' reluctance to be referred to a psychiatrist (89.1%). Most GPs (78.4%) agreed that recognizing depression was their responsibility, 71.7% were confident in diagnosing depression, but less than one-third (29.6%) considered that they should treat it.

CONCLUSIONS

Improvements to the organization of mental healthcare in all five countries should consider better training for GPs in depression diagnosis and treatment; the availability of mental healthcare specialists at primary care level, with ensured equal and easy access for all patients; and the removal of potential legal barriers for diagnosis and treatment of depression.

Frontal Alpha Asymmetry Correlates with Suicidal Behavior in Major Depressive Disorder

Objective

Based on the constant associations made between major depressive disorder (MDD) and alpha asymmetry, and MDD and suicide, this study aimed to examine the relationship between frontal alpha asymmetry and suicide in MDD patients.

Methods

Sixty-six MDD patients, of whom fifteen were male and fifty-one were female, were recruited. Independent groups were created based on the median score of frontal alpha asymmetry: the left dominant (LD) group and the right dominant (RD) group. The alpha band (8‒12 Hz) and its sub-bands (i.e., low alpha band: 8‒10 Hz; high alpha band: 10‒12 Hz) were of interest. Source level alpha asymmetry was calculated as well.

Results

Suicidal behavior was positively correlated with the asymmetry indices of the low alpha band and the alpha band in the LD group and that of the high alpha band in the RD group. Source level analysis revealed positive correlations between suicidal behavior and the asymmetry index of the low alpha band in the LD group.

Conclusion

Frontal alpha asymmetry, especially that of the low alpha band, might reflect the cognitive deficits associated with suicidal behaviors in MDD patients.

A Scoping Review of Evidence-Based Interventions for Adolescents with Depression and Suicide Related Behaviors in Low and Middle Income Countries

Depression is the number one cause of disability for adolescents. Moreover, depression is the strongest predictor for suicide, which is the second cause for death among adolescents worldwide. A total of 22 RCTs conducted in 14 different LMICs have been reviewed. This is a significant effort to provide mental health services for adolescents in LMICs. However, considering that 2/3 of the world's countries meet criteria for LMIC status and 75% of suicides occur in LMICs, more research addressing both understanding and intervention/prevention of depression and suicide must be conducted in these countries.

Efficacy and safety of oral SOCG in treatment of major depressive disorder: A protocol for a phase II, randomized, double-blind, placebo controlled, parallel-groups, dose finding exploratory study

INTRODUCTION

Major depressive disorder (MDD) is a common condition worldwide, and leads to degradation in quality of life and large socioeconomic costs. There has been increasing demand for new therapies with fewer side effects. SOCG (SOCG tablet) is a modified prescription of So-ochim-tang, which is widely used in Traditional Korean Medicine to treat MDD. We aim to evaluate the efficacy of SOCG in treating MDD, and identify the optimum dose.

DESIGN

The protocol we are following is that of a Phase II clinical trial with a randomized, double blinded, placebo controlled, and parallel design. One hundred forty-eight participants will be randomly divided into 4 groups and treated for 8 weeks.

OUTCOME MEASURES

The primary outcome will be the score in the Korean Version of the Hamilton Depression Rating Scale. Scores in the Korean version of the Beck Depression Inventory-II Korean Symptom Check List-95 (KSCL-95), State Trait Anxiety Inventory-Korean version, State- Trait Anger Expression Inventory- Korean version (STAXI-K), Insomnia Severity Index (ISI), and the EuroQol-5 Dimension (EQ-5D) will be considered as secondary outcomes.

DISCUSSION AND CONCLUSIONS

Demonstration of human safety and efficacy of SOCG in the present trial and identification of the appropriate dose will justify a New Drug Application and a phase III clinical trial. Further, we expect that this new antidepressant will be able to increase cure rates, and alleviate the burden of medical expenses.

Childhood maltreatment and risk for suicide attempts in major depression: a sex-specific approach

Background: Childhood maltreatment increases the risk of suicide attempts in the general population, possibly having similar effects among patients with major depressive disorder (MDD). The few studies that have addressed this association have been restricted to specific populations (e.g. treatment-resistant depression, personality disorders) and have rarely taken sex into account. Objective: To examine the impact of childhood maltreatment on suicide attempts among MDD patients above and beyond other risk factors and potential confounders, while considering potential sex-specific effects. Methods: The study assessed 165 patients with a principal diagnosis of MDD. Neurological alterations, psychiatric comorbidities, and drug abuse were reasons for exclusion. Logistic regressions using the whole sample, and divided by sex, were run to test the association between childhood maltreatment and history of suicide attempts, controlling for symptom severity, comorbidities, and treatment-resistant depression. Results: There was a significant and clinically relevant association between childhood maltreatment and history of suicide attempts in the total sample. Patients with childhood maltreatment were 3.01 times more likely to present a history of suicide attempts than patients without childhood maltreatment. A family history of psychiatric disorders also contributed to the variance of attempted suicide, but its interaction with childhood maltreatment was not statistically significant. When testing the model separately, the effect of childhood maltreatment on suicide attempts remained for females, whereas for males, age of MDD onset and Childhood Trauma Questionnaire minimization-denial scale were predictive variables. Conclusions: Childhood maltreatment is a clear predictor of suicidal behaviour among MDD patients, and this effect remains significant after controlling for potential confounders. Also, the sex of patients emerges as a relevant factor that may model the mechanisms underlying the prediction of suicide attempts. Since suicide is the main cause of premature death among MDD patients, interventions targeting childhood maltreatment should be included in preventive and clinical strategies.

Antisocial personality and risks of cause-specific mortality: results from the Epidemiologic Catchment Area study with 27 years of follow-up

PURPOSE

Little is known about the effect of antisocial personality disorder (ASPD) on the risks of cause-specific mortality in the community. This study aimed to close this gap by evaluating if ASPD increases risks of cause-specific mortality in population-based residential and institutionalized samples with 27 years of follow-up.

METHODS

Data were collected in four metropolitan sites as part of the Epidemiologic Catchment Area (ECA) study during 1979-1983. Records were linked to the National Death Index through the end of 2007. Cox proportional hazards models adjusted for propensity weights and sample weights were fitted to estimate the effect of ASPD on the hazard of dying.

RESULTS

420 respondents with ASPD (median survival age 71.0 years) and 15,367 without ASPD (median survival age 84.6 years) were included in this study. Those with ASPD were more likely to die from all causes (HR = 4.46; 95% CI = 2.44-8.16), suicide (HR = 2.81; 95% CI = 1.03-7.65), malignant neoplasms (HR = 4.09; 95% CI = 2.66-6.28), chronic lower respiratory disease (HR = 5.67; 95% CI = 2.92-11.0), and human immunodeficiency virus infection (HR = 8.07; 95% CI = 2.03-32.1), but not from accidents (HR = 0.58; 95% CI = 0.17-1.93) or heart disease (HR = 1.09; 95% CI = 0.43-2.76).

CONCLUSIONS

Our findings demonstrate that antisocial personality disorder is a strong predictor of all-cause mortality, and cause-specific mortality. Early identification, treatment, and prevention of ASPD are important public mental health initiatives that could reduce premature mortality among this vulnerable population.

Cognitive behavioral therapy for suicide prevention (CBT-SP): Implications for meeting standard of care expectations with suicidal patients

Accumulating evidence supports the efficacy of cognitive behavioral therapy for suicide prevention (CBT-SP) as an empirically supported treatment approach for suicidal patients. In light of these findings, several procedures pulled from CBT-SP have been recommended for standard care with suicidal patients. The present article provides an overview of the procedures used in CBT-SP and discusses how these procedures meet, or even exceed, standard of care expectations for outpatient mental healthcare clinicians. Finally, the relevance of clinician fidelity to the CBT-SP model when evaluating standard of care expectations is discussed.

Effectiveness of Psychotherapy on Suicidal Risk: A Systematic Review of Observational Studies

Background: Suicidal behavior is a major public health concern worldwide, and the interest in the development of novel and more efficient treatment strategies and therapies to reduce suicidal risk is increasing. Some recent studies have summarized the results of randomized clinical trials (RCTs) assessing the efficacy of psychotherapeutic tools designed to treat patients at suicidal risk. However, observational studies, which reflect real-world effectiveness and may use original approaches, have not been reviewed. Method: The aim of this study is to systematically review the available scientific evidence issued from observational studies on the clinical effectiveness of psychotherapeutic tools designed to treat patients at suicide risk. We have thus performed a systematic search of PubMed and Web of Science databases. Results: Out of 1578 papers, 40 original observational studies fulfilled our selection criteria. The most used psychotherapeutic treatments were dialectical behavioral therapy (DBT, 27.5%) and cognitive behavioral therapy (CBT, 15.0%) in patients with a diagnosis of borderline personality disorder (32.5%) and depression (15.0%). Despite the between-study heterogeneity, interventions lead to a reduction in suicidal outcomes, i.e., suicidal ideation (55.0%) and suicide attempts (37.5%). The content and reporting quality varied considerably between the studies. Conclusion: DBT and CBT are the most widely used psychotherapeutic interventions and show promising results in existing observational studies. Some of the included studies provide innovative approaches. Group therapies and internet-based therapies, which are cost-effective methods, are promising treatments and would need further study.

Self-Forgiveness Moderates the Effects of Depression on Suicidality

OBJECTIVE

Not all depressive individuals are suicidal. An increasing body of studies has examined forgiveness, especially self-forgiveness, as a protective factor of suicide based on that suicide is often accompanied by negative self-perceptions. However, less has been studied on how different subtypes of forgiveness (i.e., forgiveness-of-self, forgiveness-of-others and forgiveness-of-situations) could alleviate the effects of depression on suicide. Hence, this study examined forgiveness as a moderator of depression and suicidality.

METHODS

305 participants, consisted of 87 males and 218 females, were included in the study. The mean age was 41.05 (SD: 14.48; range: 19-80). Depression, anxiety, and forgiveness were measured through self-report questionnaires, and suicidal risk was measured through a structuralized interview. Moderations were examined through hierarchical regression analyses.

RESULTS

Depression positively correlated with suicidality.

RESULTS

of the hierarchical regression analysis indicated forgiveness as a moderator of depression on suicidality. Further analysis indicated only forgiveness-of-self as a significant moderator; the effects of forgiveness-of-others and forgiveness-of-situation were not significant.

CONCLUSION

These findings suggest that forgiveness-of-self is essential in reducing of the effects of depression on suicidality. It is suggested that self-acceptance and the promotion of self-forgiveness should be considered as an important factor when developing suicide prevention strategies.

Anti-Suicidal Efficacy of Repetitive Transcranial Magnetic Stimulation in Depressive Patients: A Retrospective Analysis of a Large Sample

Background: Suicide is a major public health problem. About 90% of suicide victims have one or more major psychiatric disorder, with a reported 20-fold increased risk for suicide in patients with affective disorders in comparison with healthy subjects. Repetitive transcranial magnetic stimulation (rTMS) has been established as an effective alternative or adjunctive treatment option for patients with depressive disorders, but little is known about its effects on suicide risk. Objective: For the assessment of the effectiveness of rTMS on suicidal ideation and behaviors, we performed a retrospective analysis of a large sample of patients with depressive disorders, who were treated with rTMS. Methods: We analyzed the records of 711 TMS in- and out-patients with depressive affective disorders in a tertiary referral hospital between 2002 and 2017. Out of these patients we were able to collect Hamilton depression rating scale (HAMD) data of 332 patients (180 females, 152 males; age range 20 to 79 years; mean age 47.3 ± 12.3) for which we analyzed the change of suicidal ideation by using item 3 (suicidality) of HAMD. Results: Out of all 711 patients treated with rTMS for their depression, one patient (0.1%) committed suicide during the TMS treatment. In the statistical analysis of the subsample with 332 patients there was an overall amelioration of depressive symptoms accompanied by a significant decrease in the suicidality item with a medium effect size. Decrease in suicidality was not inferior to changes in other items as indicated by effect sizes. Forty-seven percent of patients showed an amelioration in suicidality, 41.3% of patients did not show a change in their suicidality's scores, and 11.7% of patients showed an increase in suicidality's scores from baseline to final rating. Correlation of item 3 (suicidality) and item 7 (drive) demonstrated a significant positive association, revealing improved drive with a parallel decreased suicidality. Conclusion: Based on the proposed data, there is no evidence that rTMS increases the risk for suicide during the course of the treatment. Conversely, rTMS tends to reduce suicidal ideation. Our findings call for further rTMS controlled studies using large sample sizes and specific suicidality assessment measures to obtain more conclusive results.

Association between completed suicide and bipolar disorder: A systematic review of the literature

BACKGROUND

Completed suicide is a major cause of death in bipolar disorder (BD) patients.

OBJECTIVE

The aim of this paper is to provide an overall review of the existing literature of completed suicide in BD patients, including clinical and genetic data DATA SOURCES: We performed a systematic review of English and non-English articles published on MEDLINE/PubMed, PsycInfo and Cochrane database (1970-2017). Additional studies were identified by contacting clinical experts, searching bibliographies, major textbooks and website of World Health Organization. Initially we did a broad search for the association of bipolar disorder and suicide and we were narrowing the search in terms included "bipolar disorder" and "completed suicide".

STUDY SELECTION

Inclusion criteria were articles about completed suicide in patients with BD. Articles exclusively focusing on suicide attempts and suicidal behaviour have been excluded. We used PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) consensus for drafting this systematic review.

RESULTS

The initial search generated 2806 articles and a total of 61 meeting our inclusion criteria. We reviewed epidemiological data, genetic factors, risk factors and treatment of completed suicide in BD. Suicide rates in BD vary between studies but our analyses show that they are approximately 20-30-fold greater than in general population. The highest risk of successful suicide was observed in BD-II subjects. The heritability of completed suicide is about 40% and some genes related to major neurotransmitter systems have been associated with suicide. Lithium is the only treatment that has shown anti-suicide potential.

LIMITATIONS

The most important limitation of the present review is the limited existing literature on completed suicide in BD.

CONCLUSIONS

BD patients are at high risk for suicide. It is possible to identify some factors related to completed suicide, such as early onset, family history of suicide among first-degree relatives, previous attempted suicides, comorbidities and treatment. However it is necessary to promote research on this serious health problem.

The relationship between the frequency of suicidal ideation and sleep disturbance factors among adolescent earthquake victims in China

OBJECTIVE

This study aimed to examine the frequency of suicidal ideation (SI) and identify exposure variables, mental health, and sleep-related risk factors of SI among adolescents following the 2013 Ya'an earthquake.

METHODS

Participants consisted of 5563 adolescent students selected through random sampling from 11 primary and high schools in the counties most severely affected by the earthquake. They were asked to complete the Pittsburgh Sleep Quality Index, Children's Revised Impact of Event Scale-13, Short Mood and Feelings Questionnaire, and Screen for Child Anxiety-Related Emotional Disorders. Multinomial logistic analysis was used to identify possible relationships between SI and psychopathology, sleep problems, earthquake exposures or demographic characteristics. The mediation analysis was used to identify direct and indirect effects among sleep problems, psychopathology, earthquake exposures and SI.

RESULTS

Our findings suggest that 29.5% of the sample experienced SI during the past year (12.9% once, 11.9% twice, 2.6% on 3-4 occasions and 2.1% on at least 5 occasions). Multiple sleeping problems, including trouble falling asleep, shorter sleep duration, and daytime dysfunction, showed independent associations with SI. The mediation analysis suggested that depression and anxiety mainly mediated the association of sleep with SI.

LIMITATIONS

This study was cross-sectional and did not include controls. No baseline data were collected prior to the earthquake.

CONCLUSION

SI can be a serious problem among adolescents following a major earthquake, especially those who are older, who live in one-child households, or who are female. Years after a disaster, we found that exposure severity, psychopathology and sleep impairment all contributed to SI, and that earthquake exposure may have disrupted sleep and worsened mood, which in turn may have impacted SI. By enhancing teenagers' sleep management and shaping their activities, post-disaster intervention programs may help prevent SI among Chinese adolescents.

Effects of psilocybin therapy on personality structure

OBJECTIVE

To explore whether psilocybin with psychological support modulates personality parameters in patients suffering from treatment-resistant depression (TRD).

METHOD

Twenty patients with moderate or severe, unipolar, TRD received oral psilocybin (10 and 25 mg, one week apart) in a supportive setting. Personality was assessed at baseline and at 3-month follow-up using the Revised NEO Personality Inventory (NEO-PI-R), the subjective psilocybin experience with Altered State of Consciousness (ASC) scale, and depressive symptoms with QIDS-SR16.

RESULTS

Neuroticism scores significantly decreased while Extraversion increased following psilocybin therapy. These changes were in the direction of the normative NEO-PI-R data and were both predicted, in an exploratory analysis, by the degree of insightfulness experienced during the psilocybin session. Openness scores also significantly increased following psilocybin, whereas Conscientiousness showed trend-level increases, and Agreeableness did not change.

CONCLUSION

Our observation of changes in personality measures after psilocybin therapy was mostly consistent with reports of personality change in relation to conventional antidepressant treatment, although the pronounced increases in Extraversion and Openness might constitute an effect more specific to psychedelic therapy. This needs further exploration in future controlled studies, as do the brain mechanisms of postpsychedelic personality change.

Neuroimaging Studies of Suicidal Behavior and Non-suicidal Self-Injury in Psychiatric Patients: A Systematic Review

Background: With around 800,000 people taking their own lives every year, suicide is a growing health concern. Understanding the factors that underlie suicidality and identifying specific variables associated with increased risk is paramount for increasing our understanding of suicide etiology. Neuroimaging methods that enable the investigation of structural and functional brain markers in vivo are a promising tool in suicide research. Although a number of studies in clinical samples have been published to date, evidence about neuroimaging correlates for suicidality remains controversial. Objective: Patients with mental disorders have an increased risk for both suicidal behavior and non-suicidal self-injury. This manuscript aims to present an up-to-date overview of the literature on potential neuroimaging markers associated with SB and NSSI in clinical samples. We sought to identify consistently reported structural changes associated with suicidal symptoms within and across psychiatric disorders. Methods: A systematic literature search across four databases was performed to identify all English-language neuroimaging articles involving patients with at least one psychiatric diagnosis and at least one variable assessing SB or NSSI. We evaluated and screened evidence in these articles against a set of inclusion/exclusion criteria and categorized them by disease, adhering to the PRISMA guidelines. Results: Thirty-three original scientific articles investigating neuroimaging correlates of SB in psychiatric samples were found, but no single article focusing on NSSI alone. Associations between suicidality and regions in frontal and temporal cortex were reported by 15 and 9 studies across four disorders, respectively. Furthermore, differences in hippocampus were reported by four studies across three disorders. However, we found a significant lack of replicability (consistency in size and direction) of results across studies. Conclusions: Our systematic review revealed a lack of neuroimaging studies focusing on NSSI in clinical samples. We highlight several potential sources of bias in published studies, and conclude that future studies should implement more rigorous study designs to minimize bias risk. Despite several studies reporting associations between SB and anatomical differences in the frontal cortex, there was a lack of consistency across them. We conclude that better-powered samples, standardized neuroimaging and analytical protocols are needed to continue advancing knowledge in this field.

Association between Perceived Stressfulness of Stressful Life Events and the Suicidal Risk in Chinese Patients with Major Depressive Disorder

Background

Patients with major depressive disorder (MDD) usually have high risk of suicidality. Few studies have investigated the effects of stressful life events (SLEs) on the risk of suicide in Chinese patients who have developed MDD. This study aimed to investigate the impact of SLEs on suicidal risk in Chinese patients with MDD.

Methods

In total, 1029 patients with MDD were included from nine psychiatric hospitals to evaluate the impact of SLEs on suicidal risk. Patients fulfilling the Mini-International Neuropsychiatric Interview (MINI) criteria for MDD were included in the study. Patients were excluded if they had lifetime or current diagnoses of psychotic disorder, bipolar disorder, and alcohol or substance dependence. Depressive symptoms were assessed by the 17-item Hamilton Depression Scale (HAMD-17). The suicidal risk of MDD patients was determined by the suicide risk module of MINI. SLEs were assessed by the Life Events Scale.

Results

No gender difference was found for suicidal risk in MDD patients. Patients with suicidal risk had younger ages, lower education levels, more drinking behavior, and lower marriage rate, and fewer people had child and more severe depressive symptoms than nonsuicidal risk group. High-level perceived stressfulness (HPS) and number of SLEs that patients were exposed to were significantly greater in patients with suicidal risk than patients without. In multivariate logistic analysis, HPS of SLEs (odds ratio [OR] = 1.54, 95% confidence interval [CI]: 1.16-2.05, P = 0.003) and depressive symptoms (OR = 1.08, 95% CI: 1.05-1.11, P < 0.001) were associated with suicidal risk even after adjustment of gender, age, marriage, drinking behavior, and childless.

Conclusions

HPS of SLEs is associated with suicide risk in Chinese patients with MDD. Further suicide prevention programs targeting this risk factor are needed.

Reducing relapse and suicide in bipolar disorder: practical clinical approaches to identifying risk, reducing harm and engaging service users in planning and delivery of care – the PARADES (Psychoeducation, Anxiety, Relapse, Advance Directive Evaluation and Suicidality) programme

Background

Bipolar disorder (BD) costs £5.2B annually, largely as a result of incomplete recovery after inadequate treatment.

Objectives

A programme of linked studies to reduce relapse and suicide in BD.

Design

There were five workstreams (WSs): a pragmatic randomised controlled trial (RCT) of group psychoeducation (PEd) versus group peer support (PS) in the maintenance of BD (WS1); development and feasibility RCTs of integrated psychological therapy for anxiety in bipolar disorder (AIBD) and integrated for problematic alcohol use in BD (WS2 and WS3); survey and qualitative investigations of suicide and self-harm in BD (WS4); and survey and qualitative investigation of service users’ (SUs) and psychiatrists’ experience of the Mental Capacity Act 2005 (MCA), with reference to advance planning (WS5).

Setting

Participants were from England; recruitment into RCTs was limited to certain sites [East Midlands and North West (WS1); North West (WS2 and WS3)].

Participants

Aged ≥ 18 years. In WS1–3, participants had their diagnosis of BD confirmed by the Structural Clinical Interview for theDiagnostic and Statistical Manual of Mental Disorders.

Interventions

In WS1, group PEd/PS; in WS3 and WS4, individual psychological therapy for comorbid anxiety and alcohol use, respectively.

Main outcome measures

In WS1, time to relapse of bipolar episode; in WS2 and WS3, feasibility and acceptability of interventions; in WS4, prevalence and determinants of suicide and self-harm; and in WS5, professional training and support of advance planning in MCA, and SU awareness and implementation.

Results

Group PEd and PS could be routinely delivered in the NHS. The estimated median time to first bipolar relapse was 67.1 [95% confidence interval (CI) 37.3 to 90.9] weeks in PEd, compared with 48.0 (95% CI 30.6 to 65.9) weeks in PS. The adjusted hazard ratio was 0.83 (95% CI 0.62 to 1.11; likelihood ratio testp = 0.217). The interaction between the number of previous bipolar episodes (1–7 and 8–19, relative to 20+) and treatment arm was significant (χ2 = 6.80, degrees of freedom = 2;p = 0.034): PEd with one to seven episodes showed the greatest delay in time to episode. A primary economic analysis indicates that PEd is not cost-effective compared with PS. A sensitivity analysis suggests potential cost-effectiveness if decision-makers accept a cost of £37,500 per quality-adjusted life-year. AIBD and motivational interviewing (MI) cognitive–behavioural therapy (CBT) trials were feasible and acceptable in achieving recruitment and retention targets (AIBD:n = 72, 72% retention to follow-up; MI-CBT:n = 44, 75% retention) and in-depth qualitative interviews. There were no significant differences in clinical outcomes for either trial overall. The factors associated with risk of suicide and self-harm (longer duration of illness, large number of periods of inpatient care, and problems establishing diagnosis) could inform improved clinical care and specific interventions. Qualitative interviews suggested that suicide risk had been underestimated, that care needs to be more collaborative and that people need fast access to good-quality care. Despite SUs supporting advance planning and psychiatrists being trained in MCA, the use of MCA planning provisions was low, with confusion over informal and legally binding plans.

Limitations

Inferences for routine clinical practice from WS1 were limited by the absence of a ‘treatment as usual’ group.

Conclusion

The programme has contributed significantly to understanding how to improve outcomes in BD. Group PEd is being implemented in the NHS influenced by SU support.

Future work

Future work is needed to evaluate optimal approaches to psychological treatment of comorbidity in BD. In addition, work in improved risk detection in relation to suicide and self-harm in clinical services and improved training in MCA are indicated.

Feasibility and impact of data-driven learning within the suicide prevention action network of thirteen specialist mental healthcare institutions (SUPRANET Care) in the Netherlands: a study protocol

INTRODUCTION

Improvement of the quality and safety of care is associated with lower suicide rates among mental healthcare patients. In The Netherlands, about 40% of all people that die by suicide is in specialist mental healthcare. Unfortunately, the degree of implementation of suicide prevention policies and best practices within Dutch mental healthcare services is variable. Sharing and comparing outcome and performance data in confidential networks of professionals working in different organisations can be effective in reducing practice variability within and across organisations and improving quality of care.

METHODS AND ANALYSIS

Using formats of professional networks to improve surgical care (Dutch Initiative for Clinical Auditing) and somatic intensive care (National Intensive Care Evaluation), 113 Suicide Prevention has taken the lead in the formation of a Suicide Prevention Action Network (SUPRANET Care), with at present 13 large Dutch specialist mental health institutions. Data on suicide, suicide attempts and their determinants as well as consumer care policies and practices are collected biannually, after consensus rounds in which key professionals define what data are relevant to collect, how it is operationalised, retrieved and will be analysed. To evaluate the impact of SUPRANET Care, standardised suicide rates will be calculated adjusted for confounding factors. Second, the extent to which suicide attempts are being registered will be analysed with the suicide attempt data. Finally, professionals' knowledge, attitude and adherence to suicide prevention guidelines will be measured with an extended version of the Professionals In Training to STOP suicide survey.

ETHICS AND DISSEMINATION

This study has been approved by the Central Committee on Research Involving Human Subjects, The Netherlands. This study does not fall under the scope of the Medical Research Involving Human Subjects Act (WMO) or the General Data Protection Regulation as stated by the Dutch Data Protection Authority because data are collected on an aggregated level.

The Challenges of Predicting Suicidal Thoughts and Behaviours in a Sample of Rural Australians with Depression

Suicide is a leading cause of death, particularly in rural and remote areas. Although depression is strongly related to both suicidal ideation and attempt, it lacks specificity as a predictor, and little is known about characteristics that increase suicide risk among people with depression. A telephone version of the World Mental Health Composite International Diagnostic Interview explored lifetime depression, suicidal ideation, suicide attempt, and related factors among a community-dwelling sample of rural and remote Australians, selected for an interview based on a screener for psychological distress (100% of those with high distress, 75% of those with moderate distress, and 16% of those with low distress). Of 1051 participants interviewed, 364 reported lifetime symptoms of depression; of these, 48% reported lifetime suicidal ideation and 16% reported a lifetime suicide attempt. While depression severity was a significant correlate of suicidality for both males and females, suicide attempt was significantly more common among females with a younger age of depression onset, and a higher number of psychiatric comorbidities. No additional factors were significant for males. Among rural and remote residents with lifetime symptoms of depression, the identification of suicide risk may be enhanced by considering individual and contextual factors beyond depression severity. Further research focusing on risk factors for males would be beneficial.

Suicide deaths by intentional self-poisoning in people with cardiovascular disease

OBJECTIVE

We aimed to characterize self-poisoning deaths in people with cardiovascular disease (CVD) and compare to other suicide decedent groups.

METHODS

Suicide deaths by self-poisoning in people with CVD (n = 151) were compared to suicide deaths by other methods in people with CVD (n = 260) and suicide deaths by self-poisoning in people without CVD (n = 509). Sub-analysis of the CVD self-poisoning group compared people with depression and without depression. Toxicology reports were compared between intentional self-poisoning groups.

RESULTS

A higher proportion of suicide deaths were due to self-poisoning in the CVD group compared to the non-CVD group. People with CVD were less likely to have any identified stressor (excluding medical stressor) prior to dying from self-poisoning compared to those without CVD. Female sex, past suicide attempts, living circumstances, and comorbid substance abuse were each significantly associated with self-poisoning as the method of suicide in people with CVD. Opioid, any antidepressants, benzodiazepines, and tricyclic antidepressants (TCAs) were commonly identified as lethal in people with CVD. Compared to people in the CVD self-poisoning without depression group, people in the CVD self-poisoning with depression group were more likely to have lethal levels of TCAs.

CONCLUSIONS

Our findings characterize suicide deaths in people with CVD, and identified notable differences based on method of death and presence of depression.

Suicide attempts and emotion regulation in psychiatric outpatients

BACKGROUND

Suicidal behavior has been associated with maladaptive strategies for emotion regulation; however, limited research has explored this association after controlling for diagnosis. This study aims to explore this connection across diagnoses. We hypothesized that patients who reported greater difficulty with emotion regulation would be more likely to have made suicide attempts.

METHOD

Participants included 1046 psychiatric outpatients. Diagnoses and information about suicide history were determined using semi-structured interviews. Patients also completed the Difficulties in Emotion Regulation Scale (DERS). Analyses were conducted to determine the relationships between emotion regulation difficulties and lifetime suicide attempts.

RESULTS

Emotion regulation difficulties did not independently predict suicidal behavior. After controlling for the contribution of emotion dysregulation on lifetime suicide attempts, diagnoses of borderline personality disorder and posttraumatic stress disorder were the only disorders independently associated with a history of suicidal behavior.

LIMITATIONS

The generalizability of our findings may be limited based on the sample's demographic characteristics and low base rate of suicide attempts. This study was cross-sectional in nature; therefore, the predictive capacity of either DERS scores or psychiatric diagnoses in terms of future suicidal behavior could not be determined.

CONCLUSIONS

The independent effect of emotion dysregulation on suicidal behavior was negated after controlling for psychiatric diagnosis. Individuals with certain disorders tend to make suicide attempts for reasons that are distinct from emotion dysregulation, whereas emotion dysregulation may be at the core of suicidality for individuals with other clinical presentations.

Are there differences in lipid peroxidation and immune biomarkers between major depression and bipolar disorder: Effects of melancholia, atypical depression, severity of illness, episode number, suicidal ideation and prior suicide attempts

BACKGROUND

There is evidence that major depression (MDD) and bipolar disorder (BD) are accompanied by activated immune & oxidative (I&O) pathways.

METHODS

To compare I&O biomarkers between MDD and BD we assessed serum levels of thiobarbituric acid reactive substances (TBARS; a lipid peroxidation marker), soluble interleukin-2 receptor (sIL-2R), sIL-6R, IL-α, sIL-1R antagonist (sIL-1RA), tumor necrosis factor receptor 60kDa/80kDa (sTNFR60/R80) in 114 MDD and 133 BD patients, and 50 healthy controls. We computed z-unit weighted indices reflecting the 5 cytokine receptor levels (zCytR), cell-mediated immunity (zCMI) and I&O pathways (zCMI+TBARS).

RESULTS

There are no significant differences in biomarkers between MDD and BD. BD/MDD with atypical features is characterized by increased sIL-6R and TBARS, whereas melancholia is associated with higher TBARS and lower sTNFR60 levels. Severity of illness, as measured with the Hamilton Depression Rating Scale, is correlated with increased sIL-6R, sTNFR80, TBARS, zCytR and zCMI+TBARS. The number of episodes the year prior to blood sampling is positively associated with sTNFR80, TBARS, zCMI, zCMI+TBARS, while number of hospitalizations is positively associated with sIL-1RA. Prior suicidal attempts are associated with increased sIL-1RA, IL-1α, zCMI, TBARS and zCMI+TBARS, while TBARS is associated with current suicidal ideation.

CONCLUSIONS

There are no I&O biomarker differences between MDD and BD. Atypical depression is associated with increased IL-6 trans-signaling and lipid peroxidation. Severity of depression, number of episodes and suicidal attempts are associated with activated I&O pathways. Increased TBARS is the single best predictor of BD/MDD, atypical depression, melancholia and current suicidal ideation.

Risk factors for multiple suicide attempts among Roma in Hungary

In recent years, suicide rates in Hungary have been among the highest in the European Union. Attempted suicide rates in the Roma population are 2-3 times higher than in the non-Roma population. Since individuals making multiple attempts have a higher pro-bability of eventual death by suicide, and there are limited data on suicidal behaviour of the Roma population, the aim of this study was to explore the sociodemographic and psychological background factors of multiple suicide attempts in the Hungarian Roma population. Semistructured interviews were conducted with 150 individuals admitted to hospital toxicology departments, who made suicide attempts by deliberate self-poisoning, 65 of whom were multiple attempters. Detailed information regarding the current attempt and previous suicidal acts was recorded. Patients also completed the Shortened Beck Depression, the Beck Hopelessness Questionnaire, and the Social Support Questionnaire. Independent samples t-tests were used to evaluate differences in psychological variables between the Roma ( N = 90) and non-Roma ( N = 60) groups. Stepwise linear regression and odds ratios analyses were performed to identify potential background factors of multiple suicide attempts. There was a significantly higher level of previous suicidal events among the Roma in the sample population (3.53 vs. 0.84, p < .001). Roma ethnicity was found to be a strong predictor of multiple suicide attempts. Current major depression, hopelessness, and diagnosed mood disorder were identified as significant risk factors of repeated attempts. Smoking (OR = 5.4), family history of suicide (OR = 4.9), and long-term unemployment (OR = 4.6) were additional risk factors among Roma patients. A thorough understanding of the ethnicity-specific risk factors for multiple suicide attempts could facilitate the development of effective intervention and postvention programmes.

"Our lifestyle is a mix-match": Traditional healers talk about suicide and suicide prevention in South Africa

Practitioners of traditional African medicine (traditional healers) are an important part of the health care system in South Africa, yet their voices are often absent from discussions about public health. In this context, we set out to investigate how a group of traditional healers in South Africa understand suicide and suicide prevention. In-depth, semistructured interviews were conducted with 6 traditional healers and analysed using thematic content analysis. The traditional healers report they are frequently consulted by suicidal individuals and they are confident about their ability to help people in a suicidal crisis. Findings suggest that traditional healers understand suicidal behaviour as a symptom of social disconnection and cultural discontinuity. Traditional healers report that suicidal individuals can be helped by reestablishing interpersonal connections, reconnecting to family and ancestors, and renewing their cultural identities through rituals. These findings suggest that there is some congruence between the way traditional healers understand suicide and the Western scientific and biomedical literature. Our findings raise important questions about cultural approaches to suicide research which are commonly premised on dualistic thinking that constructs culture as something distinct from Western biomedicine.

Positive and Negative Suicide Ideation (PANSI) Inventory: Initial Psychometric Properties as a Suicide Risk Screening Tool Among Nigerian University Students

Objective:

The objective of this study is to examine the factor structure, validity, reliability, and the screening properties as a suicide risk assessment tool of the 14-item Positive and Negative Suicide Ideation (PANSI) in a nonclinical sample of Nigerian university students.

Methods:

A total of 514 students completed the PANSI, in addition to the Beck Depression Inventory-II (BDI-II) and the General Health Questionnaire-12 (GHQ-12).

Results:

Prior to the factor analysis, the sample was randomly divided into two. In one half of the sample (sample 1), exploratory factor analysis of the inventory yielded a 2-factor model (Negative Suicide Ideation [PANSI-NSI] and Positive Ideation [PANSI-PI]), whereas confirmatory factor analysis in the other half (sample 2) produced a 2-factor model with indices of fitness that indicated a satisfactory model fit ( c2 = 93.8; df = 67; χ2/degree of freedom = 1.400; P = .017; goodness of fit index = 0.951; Tucker-Lewis index = 0.964; comparative fit index = 0.974; root mean square error of approximation = 0.040). The internal consistencies of the items of the PANSI-PI and PANSI-NSI subscales were 0.75 and 0.79, respectively. The construct validity of the 2 subscales was modestly satisfactory: PANSI-PI had negative correlations with the GHQ-12 ( r = −.239, P < .001) and the BDI-II ( r = −.190, P < .001), whereas the PANSI-NSI had positive correlations with the GHQ-12 ( r = .248, P < .001) and the BDI-II ( r = .376, P < .001). In addition, a cutoff total score of 17 on the PANSI-NSI was associated with the best sensitivity (80.0%) and specificity (92.5%) in the identification of those students who endorsed experiencing suicidal ideation (area under the curve = 0.82, 95% confidence interval = 0.58-1.00).

Conclusions:

The PANSI has exhibited satisfactory psychometric properties as a self-rated suicidal behavior assessment instrument in the evaluation of the positive and negative thoughts associated with suicidal ideation among Nigerian university students.

Prevalence of suicidal behaviors in patients with major depressive disorder in China: A comprehensive meta-analysis

BACKGROUND

Suicidal behaviors are common in major depressive disorder (MDD) and contribute significantly to premature death. The objective of this meta-analysis is to estimate the pooled prevalence of suicidal behaviors in patients with MDD in China.

METHODS

The relevant databases in English (PubMed, Embase, PsycINFO and Cochrane Library) and Chinese (Chinese National Knowledge Infrastructure, Wanfang and Chinese Biological Medical Literature) were systematically and independently searched from their inceptions until January 23, 2017. Original studies that reported the prevalence of suicidal behaviors including suicidal ideation (SI), suicide plan (SP), suicide attempt (SA) and completed suicide (CS) were included.

RESULTS

Thirty three articles that met the inclusion criteria were analyzed. The pooled lifetime prevalence of SI, SP and SA were 53.1% (95% CI: 42.4-63.4%), 17.5% (95% CI: 5.8-42.3%) and 23.7% (95% CI: 19.9-28.0%), respectively. One-month prevalence of SI and SA were 27.7% (95% CI: 15.4-44.5%) and 20.3% (95% CI: 12.1-32.2%), respectively. The pooled prevalence of SA during hospitalization and after onset of MDD were 17.3% (95% CI: 12.4-23.7%) and 42.1% (95% CI: 26.1-60.0%), respectively. Subgroup analyses revealed significant differences in both lifetime prevalence of SI and SA between genders, and between outpatients and inpatients with MDD.

CONCLUSION

Suicidal behaviors are common in MDD patients in China. Regular screening and effective intervention for suicidal behavior in MDD patients are warranted.

Interpersonal rejection sensitivity mediates the associations between peer victimization and two high-risk outcomes

BACKGROUND

Previous research has demonstrated a strong link between peer victimization and suicidal ideation and aggression. This study examined interpersonal rejection sensitivity as a mediator of these associations.

METHOD

Diagnostic interviews and assessments were administered to 80 psychiatrically hospitalized adolescents and their parents.

RESULTS

Interpersonal rejection sensitivity mediated the association between peer victimization and suicidal ideation as well as aggression after controlling for participant sex and mood disorder diagnosis.

CONCLUSION

Interpersonal rejection sensitivity influences the relation between peer victimization and mental health symptoms, including suicidal ideation and aggression. Assessing for and addressing heightened interpersonal rejection sensitivity among adolescents who have been victimized by peers may decrease the likelihood of negative mental health outcomes. Implications, especially for clinicians, are further discussed.

Depressed Multiple-Suicide­Attempters – A High-Risk Phenotype

Abstract. Background: There is compelling evidence that suicide attempts are among the strongest predictors of suicide and future suicide attempts. Aim: This study aimed to examine psychopathology in multiple-suicide attempters. Method: We compared the demographic and clinical features of three groups: depressed patients without a history of suicide attempts (non-attempters), depressed patients with a history of one to three suicide attempts (attempters), and depressed patients with a history of four or more suicide attempts (multiple attempters). Results: We found that attempters and multiple attempters had higher levels of depression, hopelessness, aggression, hostility, and impulsivity and were more likely to have borderline personality disorder and family history of major depression or alcohol use disorder compared with non-attempters, but did not differ between each other on these measures. Multiple attempters had greater suicidal ideation at study entry and were more likely to have family history of suicide attempt compared with attempters. Importantly, multiple attempters had greater suicide intent at the time of the most medically serious suicide attempt and more serious medical consequences during their most medically serious suicide attempt compared with attempters. Limitations: The cross-sectional design of the study. Conclusion: Our data suggest that multiple-suicide attempters require careful evaluation as their behavior can have serious medical consequences.

Fronto-limbic disconnection in depressed patients with suicidal ideation: A resting-state functional connectivity study

BACKGROUND

Suicidal ideation (SI) is highly prevalent and a known symptom of Major Depressive Disorder (MDD), but its underlying biological mechanisms are relatively unknown. Several studies linked suicidal ideation to dysfunctional brain circuits, specifically fronto-limbic connections. The purpose of this work was to investigate fronto-limbic disconnection in MDD patients with or without SI.

METHODS

MDD patients with SI (SI, n=28) or without SI (NSI, n=20), identified by the Scale for Suicide Ideation and healthy controls (HCs, n=30) underwent resting-state functional MRI scanning. The functional properties of correlations in neural activity (intrinsic functional connectivity, iFC) of the rostral anterior cingulate cortex (rACC) were analyzed among the three groups. Furthermore, correlation analyses between iFC, SI severity and depression severity were performed.

RESULTS

We found that the SI group exhibited decreased iFC between the rACC, the orbitomedial prefrontal cortex and the right middle temporal pole compared to HCs and NSI groups. The NSI group showed decreased iFC between the rACC and the orbitomedial prefrontal cortex compared to HCs. In the SI group, iFC strength between the right rACC and the middle temporal pole positively correlated with SI severity.

CONCLUSION

Transdiagnostic and diagnosis-specific alterations of fronto-limbic iFC were found in MDD patients with or without SI. Disrupted fronto-limbic circuits may impact decision-making and emotional processing in SI. These results provide useful information about the pathophysiological mechanisms of MDD patients with SI.

Subcortical brain structure and suicidal behaviour in major depressive disorder: a meta-analysis from the ENIGMA-MDD working group

The aetiology of suicidal behaviour is complex, and knowledge about its neurobiological mechanisms is limited. Neuroimaging methods provide a noninvasive approach to explore the neural correlates of suicide vulnerability in vivo. The ENIGMA-MDD Working Group is an international collaboration evaluating neuroimaging and clinical data from thousands of individuals collected by research groups from around the world. Here we present analyses in a subset sample (n=3097) for whom suicidality data were available. Prevalence of suicidal symptoms among major depressive disorder (MDD) cases ranged between 29 and 69% across cohorts. We compared mean subcortical grey matter volumes, lateral ventricle volumes and total intracranial volume (ICV) in MDD patients with suicidal symptoms (N=451) vs healthy controls (N=1996) or MDD patients with no suicidal symptoms (N=650). MDD patients reporting suicidal plans or attempts showed a smaller ICV (P=4.12 × 10^-3) or a 2.87% smaller volume compared with controls (Cohen's d=-0.284). In addition, we observed a nonsignificant trend in which MDD cases with suicidal symptoms had smaller subcortical volumes and larger ventricular volumes compared with controls. Finally, no significant differences (P=0.28-0.97) were found between MDD patients with and those without suicidal symptoms for any of the brain volume measures. This is by far the largest neuroimaging meta-analysis of suicidal behaviour in MDD to date. Our results did not replicate previous reports of association between subcortical brain structure and suicidality and highlight the need for collecting better-powered imaging samples and using improved suicidality assessment instruments.

Suicidal Ideation vs. Suicide Attempts: Clinical and Psychosocial Profile Differences Among Depressed Patients: A Study on Personality Traits, Psychopathological Variables, and Sociodemographic Factors in 228 Patients

This study investigated whether personality traits, psychopathological characteristics, and sociodemographic factors in depressed patients differentiate patients with only suicidal thoughts from those who have attempted suicide. We investigated two groups of patients with an affective disorder: 198 patients with a suicide attempt within the last 3 months (sex ratio male to female, 1:1.3; mean age male to female, 44.8/44.7 years) and 30 patients without a suicide attempt but with suicidal thoughts (sex ratio male to female, 1:2; mean age male to female, 39.4/42.6 years) using a comprehensive measurement (Mini-International Neuropsychiatric Interview, Structured Clinical Interview for DSM-4 Axis II disorders, Hamilton Depression Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, Hamilton Anxiety Scale, Brief Psychiatric Rating Scale, Clinical Global Impression Scale, Beck-Hopelessness Scale, Scale for Suicide Ideation, Impulsivity Rating Scale, Barratt Impulsivity Scale, Inventory for the Assessment of Aggression Factors, State-Trait Anger Expression Inventory, Ways of Coping Checklist). Several differences distinguished the two groups, namely, in personality traits such as anxiety or coping strategies and sociodemographics (e.g., education level). Personality traits, psychopathological characteristics, and sociodemographic factors are useful tools for assessing suicidal risk. Our findings encourage us to suggest that clinicians pay particular attention to sociodemographic variables such as separation/divorce and a lower education level when conducting risk assessments on suicidal patients.

A Novel Therapy for People Who Attempt Suicide and Why We Need New Models of Suicide

This paper presents a model of suicidal behaviour based on suicide as a goal-directed action, and its implications. An action theoretical model has guided the authors in the development of a brief therapy for individuals who attempt suicide (ASSIP—Attempted Suicide Short Intervention Program). Key elements are an early therapeutic alliance, narrative interviewing, psychoeducation, a joint case conceptualization, safety planning, and regular letters over 24 months. In a randomized controlled trial, ASSIP was highly effective in reducing the risk of suicide reattempts. The therapeutic elements in this treatment are described and possible implications for future directions in clinical suicide prevention discussed.

The 12-month prevalence of depression and health care utilization in the general population of Latvia

BACKGROUND

This cross-sectional study aims to assess the 12-month prevalence of major and minor depression in the Latvian population, and to evaluate associated health care utilization.

METHODS

Trained interviewers conducted face-to-face interviews with a multistage stratified probability sample of the Latvian general population, ages 15-64 (n=3003). Participants were interviewed using the depression module of the Mini International Neuropsychiatric Interview. Self-reported health care utilization and somatic illness were also assessed. Multinomial logistic regressions were applied.

RESULTS

The 12-month prevalence of major depression was 7.9% (95%CI 7.0-8.9), while for minor depression it was 7.7% (95%CI 6.8-8.7). We did not find a substantial difference in the relative risk ratio (RRR 1.7 for female) for having major depression by gender. RRR of having major depression was higher for those who had used healthcare services six or more times (RRR 2.0), those who had three or more somatic disorders during the past 12 months (RRR 2.3), those who perceived their health status as being below average (RRR 8.3), and those who were occasional smokers (RRR 3.0). RRR of having minor depression was increased for those who had at least three somatic disorders (RRR 2.3), those who received disability pension (RRR 1.9), and those who perceived their health status to be below average (RRR 3.0).

LIMITATIONS

The study was cross-sectional. Other psychiatric comorbidity was not assessed.

CONCLUSIONS

This is the first population based study reporting the 12-month prevalence of depression in Latvia. Certain factors associated with depression have been found.

The role of physical and mental health multimorbidity in suicidal ideation

BACKGROUND

Previous research has focused on the separate roles of mental illness and physical health conditions in suicide risk, with relatively few studies investigating the importance of physical and psychiatric disorder co-occurrence. We aimed to investigate whether suicidal ideation might be influenced by physical and mental ill-health multimorbidity.

METHODS

Data from the Adult Psychiatric Morbidity Survey of England were analysed. Participants who responded to the suicidal thoughts question were grouped into four distinct categories based on their health conditions (Common mental disorders (CMD) only, physical health conditions only, CMD/physical health multimorbidity and a control group with neither physical nor mental health conditions). Multinomial logistic regression analyses were conducted and odds ratios (OR) and 95% CIs are presented.

RESULTS

In the fully adjusted model, both the multimorbidity and CMD-only groups were associated with higher levels of suicidal ideation relative to the control group.

LIMITATIONS

Secondary analyses of cross-sectional data.

CONCLUSIONS

Although multimorbidity was associated with suicidal thoughts, it does not appear to elevate risk beyond the independent effects of common mental disorders or physical health problems. Primary care and mental health clinicians should consider assessment of suicidal ideation among patients with multimorbid physical/mental health conditions.

Association Between Lifetime Headache and History of Suicide Attempts in the Elderly

Background

Pain-related conditions have been reported to play a key role among risk factors for suicide. Headache in particular has been repeatedly associated with suicidal thoughts and behaviors. The aims of this study were: 1) to assess the association between lifetime headache (both non-migrainous headache and migraine) and lifetime suicide attempts (SA); 2) to differentiate, within subjects with lifetime SA, patients with and without lifetime headache in terms of socio-demographic and clinical features.

Methods

We studied 1965 subjects from a cohort of community-dwelling persons aged 65 years and over without dementia (the ESPRIT study), divided in two groups: those with (n = 75), and those without a lifetime SA (n = 1890). Logistic regression analyses were used to compare these groups according to lifetime headache status.

Results

After adjusting for gender, living alone, tobacco and alcohol consumption, and depressive, manic/hypomanic and anxiety disorders, lifetime headache frequency was significantly higher in subjects with a lifetime SA compared with controls (OR = 1.92 [1.17–3.15]). Additionally, different factors were identified as being associated with lifetime SA in participants with lifetime headache (female gender, a lower level of high-density lipoprotein cholesterol, insomnia, lifetime major depression) versus participants without headache (glycemia and lifetime major depression).

Conclusions

Lifetime headache was associated with lifetime SA. Subjects who are women and report the co-occurrence of headache and insomnia as well as lifetime major depression require higher attention and a careful screening for suicidal thoughts and behaviors.

Prediction of near-term increases in suicidal ideation in recently depressed patients with bipolar II disorder using intensive longitudinal data

BACKGROUND

There are substantial gaps in understanding near-term precursors of suicidal ideation in bipolar II disorder. We evaluated whether repeated patient-reported mood and energy ratings predicted subsequent near-term increases in suicide ideation.

METHODS

Secondary data were used from 86 depressed adults with bipolar II disorder enrolled in one of 3 clinical trials evaluating Interpersonal and Social Rhythm Therapy and/or pharmacotherapy as treatments for depression. Twenty weeks of daily mood and energy ratings and weekly Hamilton Depression Rating Scale (HDRS) were obtained. Penalized regression was used to model trajectories of daily mood and energy ratings in the 3 week window prior to HDRS Suicide Item ratings.

RESULTS

Participants completed an average of 68.6 (sd=52) days of mood and energy ratings. Aggregated across the sample, 22% of the 1675 HDRS Suicide Item ratings were non-zero, indicating presence of at least some suicidal thoughts. A cross-validated model with longitudinal ratings of energy and depressed mood within the three weeks prior to HDRS ratings resulted in an AUC of 0.91 for HDRS Suicide item >2, accounting for twice the variation when compared to baseline HDRS ratings. Energy, both at low and high levels, was an earlier predictor than mood.

LIMITATIONS

Data derived from a heterogeneous treated sample may not generalize to naturalistic samples. Identified suicidal behavior was absent from the sample so it could not be predicted.

CONCLUSIONS

Prediction models coupled with intensively gathered longitudinal data may shed light on the dynamic course of near-term risk factors for suicidal ideation in bipolar II disorder.

Combining emotion regulation and mindfulness skills for preventing depression relapse: a randomized-controlled study

BACKGROUND

Dialectical behavioral therapy (DBT) skills have become increasingly used to treat several psychiatric conditions, including major depressive disorder (MDD). The aim of the study was to investigate the efficacy of an intervention that combines emotion regulation and mindfulness skills of DBT to prevent depression relapse/recurrence.

METHODS

A total of 75 individuals (79% females; mean age, 52 years) with a diagnosis of MDD in complete or partial remission were recruited. Participants were randomly allocated either to an intervention combining emotion regulation and mindfulness skills (ER + M group, n = 37) or to a psychoeducative program (n = 38). After the 10-week treatment period, participants were followed for 1 year. Analyses were run in per-protocol (PP) and intention-to-treat (ITT) samples. The primary outcome measure was time to depression relapse/recurrence.

RESULTS

ER + M training was not more effective than the control intervention in preventing depression relapse. However, PP and ITT analyses showed that participants trained in ER + M presented a significant reduction in depressive symptoms and overall psychopathology. Based on the PP and ITT analyses, neither of the interventions were related with an increase in dispositional mindfulness.

CONCLUSIONS

More studies are needed to confirm the efficacy of ER + M to decrease depressive symptoms and overall psychopathology.

Comparative risk of self-harm hospitalization amongst depressive disorder patients using different antidepressants: a population-based cohort study in Taiwan

BACKGROUND

The aim of the study was to evaluate the comparative risk of self-harm associated with the use of different antidepressants.

METHOD

A cohort study was conducted using data from Taiwan's National Health Insurance Research Database from 2001 to 2012. A total of 751 606 new antidepressant users with depressive disorders were included. The study outcome was hospitalization due to self-harm (International Classification of Diseases, Ninth Revision, Clinical Modification codes: E950-E958 and E980-E988). Cox proportional hazards models with stratification of the propensity score deciles were used to estimate the hazard ratios of self-harm hospitalization during the first year following the initiation of antidepressant treatment.

RESULTS

There were 1038 hospitalization episodes due to self-harm that occurred during the follow-up of 149 796 person-years, with an overall incidence rate of 6.9 [95% confidence interval (CI) 6.5-7.4] per 1000. Compared with fluoxetine, the risk of self-harm hospitalization was higher for maprotiline [adjusted hazard ratio (aHR) = 3.00, 95% CI 1.40-6.45], milnacipran (aHR = 2.34, 95% CI 1.24-4.43) and mirtazapine (aHR = 1.40, 95% CI 1.06-1.86), lower for bupropion (aHR = 0.51, 95% CI 0.30-0.86), and similar level of risk was found for other selective serotonin reuptake inhibitors (citalopram, escitalopram, fluvoxamine, paroxetine and sertraline).

CONCLUSIONS

The risk of self-harm may vary across different antidepressant drugs. It would be of importance to conduct further research to investigate the influence of antidepressant use on self-harm behaviors.

Clinical features and psychiatric comorbidities of borderline personality disorder patients with versus without a history of suicide attempt

Patients with borderline personality disorder (BPD) are at high risk for suicidal behavior. However, many BPD patients do not engage in suicidal behavior. In this study, we compared clinical features of BPD patients with or without a history of suicide attempts and healthy volunteers. Compared with healthy volunteers, both BPD groups had higher Affective Lability Scale (ALS), ALS - Depression-Anxiety Subscale, Barratt Impulsivity Scale (BIS), and Lifetime History of Aggression (LHA) scores and were more likely to have a history of temper tantrums. BPD suicide attempters had higher ALS, ALS - Depression-Anxiety Subscale and LHA scores and were more likely to have a history of non-suicidal self-injury or temper tantrums compared to BPD non-attempters. Also, BPD suicide attempters were more likely to have a history of comorbid major depressive disorder and less likely to have comorbid narcissistic personality disorder (NPD) in comparison to BPD non-attempters. About 50% of study participants in each BPD group had a history of comorbid substance use disorder (SUD). Our study indicates that BPD patients with a history of suicide attempt are more aggressive, affectively dysregulated and less narcissistic than BPD suicide non-attempters.

Suicidal ideation and behaviour among persons seeking HIV testing in peri-urban areas of Cape Town, South Africa: a lost opportunity for suicide prevention

Suicidal ideation and behaviour (SIB) are among the psychiatric sequela of HIV/AIDS. Few studies have however examined the prevalence and correlates of SIB among persons seeking HIV testing. We set out to document the prevalence and correlates of SIB among people seeking HIV testing in peri-urban areas of Cape Town, South Africa (SA). A cross-sectional research design was used to recruit a sample (n = 500) of individuals seeking HIV testing. Self-report measures were used to assess two-week prevalence of SIB as well as life-time prevalence of suicide attempt. A structured clinical interview was used to assess common mental disorders (CMDs). Regression analysis was used to determine if CMD and socio-demographic variables predicted suicidal ideation. The mean age of the sample was 36 years, 51.6% were female and 46.6% were unemployed. The two-week prevalence of suicidal ideation was 24.27% while the two-week prevalence of suicide attempt and suicide plans was 2.8%. Suicidal ideation was not associated with age, gender, employment status, family income or household food insecurity. CMDs were significantly associated with suicidal ideation; individuals with depressive disorders were approximately 5.5 times more likely to report suicidal ideation, while those with generalised anxiety disorder, trauma-related disorders and alcohol use disorder were approximately 7, 4.7 and 2.8 times more likely to report suicidal ideation, respectively. Results suggest that persons seeking HIV testing may be a well-delineated group of persons at risk of suicide in this region of SA. Contact with the health care system during HIV testing provides an opportunity for targeted suicide prevention interventions in what appears to be a high risk group.

Sleep disorders and risk of hospitalization in patients with mood disorders: Analysis of the National Sample Cohort over 10 years

Medical utilization due to organic sleep disorders has increased remarkably in South Korea, which may contribute to the deterioration of mental health in the population. We analyzed the relationship between organic sleep disorders and risk of hospitalization due to mood disorder. We used data from the National Health Insurance Service (NHIS) National Sample Cohort 2002-2013, which included medical claims filed for the 15,537 patients who were newly diagnosed with a mood disorder in a metropolitan region, and employed Poisson regression analysis using generalized estimating equation (GEE) models. By the results, there was a 0.53% hospital admission rate among 244,257 patients with outpatient care visits. Patients previously diagnosed with an organic sleep disorder before specific outpatient care had a higher risk for hospitalization. Such associations were significant in females, patients with a longer duration of disease, or those who lived in the largest cities. In conclusion, considering that experiencing a sleep disorder by a patient with an existing mood disorder was associated with deterioration of their status, health policy makers need to consider insurance coverage for all types of sleep disorders in patients with psychological conditions.

Clinical outcomes of long-acting injectable risperidone in patients with bipolar I disorder: A 1-year retrospective cohort study

OBJECTIVES

We explored the effect of risperidone long-acting injection (LAI) treatment on patients with bipolar I disorder in a real-world setting.

METHODS

In this retrospective cohort study, 469 patients with bipolar I disorder were enrolled and treated with risperidone LAI and different oral antipsychotics and followed for 1 year. Concomitant medications, such as mood stabilizers, antidepressant, anxiolytics, hypnotics, or anticholinergics, were administered. On the basis of risperidone LAI use and treatment compliance, the patients were classified into 4 groups: the first long-acting injectable antipsychotics (LAI1) group (compliant patients receiving risperidone LAI treatment) (N=44), the second long-acting injectable antipsychotics (LAI2) group (non-compliant patients receiving risperidone LAI treatment) (N=33), the first non-LAI (NLAI1) group (compliant patients receiving oral medications) (N =337), and the second non-LAI (NLAI2) group (non-compliant patients receiving oral medications) (N=55). The rate of re-hospitalization, length of hospital stay, and rate of emergency room visit were assessed.

RESULTS

Compared with the non-LAI groups, the LAI groups had longer mean duration of illness (8.5 years, P=0.0001), higher rate of admission due to mood episodes (P<0.0001), depressive episodes (P<0.0001), or manic episodes (P=0.0002), and higher rate of emergency room visit (P=0.0003) before enrollment. After a 1-year follow-up, re-hospitalization rates were significantly lower in the LAI1 group than that before enrollment for any episodes (P=0.0001), manic episodes (P=0.005), and depressive episodes (P=0.002). The rates of emergency room visit were significantly lower in the LAI1 (P=0.0001), LAI2 (P=0.013), and NLAI1 (P=0.0001) groups compared with those before enrollment.

CONCLUSIONS

Risperidone LAI reduces the clinical severity of bipolar I disorder.

Resting-state functional MRI of abnormal baseline brain activity in young depressed patients with and without suicidal behavior

BACKGROUND

Suicide among youth is a major public health challenge, attracting increasing attention. However, the neurobiological mechanisms and the pathophysiology underlying suicidal behavior in depressed youths are still unclear. The fMRI enables a better understanding of functional changes in the brains of young suicide attempters with depressive disorder through detecting spontaneous neural activity. The purpose of this study was to identify the relationship between abnormalities involving local brain function and suicidal attempts in depressed youths using resting-state fMRI (RS-fMRI).

METHOD

Thirty-five depressed youths aged between 15 and 29 years with a history of suicidal attempts (SU group), 18 patients without suicidal attempts (NSU group) and 47 gender-, age- and education-matched healthy controls (HC) underwent psychological assessment and R-fMRI. The differences in fractional amplitude of low-frequency fluctuation (ALFF) among the three groups were compared. The clinical factors correlated with z-score ALFF in the regions displaying significant group differences were investigated. The ROC method was used to evaluate these clusters as markers to screen patients with suicidal behavior.

RESULTS

Compared with the NSU and HC groups, the SU group showed increased zALFF in the right superior temporal gyrus (r-STG), left middle temporal gyrus (L-MTG) and left middle occipital gyrus (L-MOG). Additionally, significantly decreased zALFF values in the L-SFG and L-MFG were found in the SU group compared with the NSU group, which were negatively correlated with BIS scores in the SU group. Further ROC analysis revealed that the mean zALFF values in these two regions (sensitivity=83.3% and specificity=71.4%) served as markers to differentiate the two patient subtypes.

CONCLUSION

The SU group had abnormal spontaneous neural activity during the resting state, and decreased activity in L-SFG and L-MFG was associated with increased impulsivity in SU group. Our results suggested that abnormal neural activity in these brain regions may represent a potential neurobiological diathesis or predisposition to suicidal behavior in youth depression.

Describing the population health burden of depression: health-adjusted life expectancy by depression status in Canada

INTRODUCTION

Few studies have evaluated the impact of depression in terms of losses to both premature mortality and health-related quality of life (HRQOL) on the overall population. Health-adjusted life expectancy (HALE) is a summary measure of population health that combines both morbidity and mortality into a single summary statistic that describes the current health status of a population.

METHODS

We estimated HALE for the Canadian adult population according to depression status. National Population Health Survey (NPHS) participants 20 years and older (n = 12 373) were followed for mortality outcomes from 1994 to 2009, based on depression status. Depression was defined as having likely experienced a major depressive episode in the previous year as measured by the Composite International Diagnostic Interview Short Form. Life expectancy was estimated by building period abridged life tables by sex and depression status using the relative risks of mortality from the NPHS and mortality data from the Canadian Chronic Disease Surveillance System (2007-2009). The Canadian Community Health Survey (2009/10) provided estimates of depression prevalence and Health Utilities Index as a measure of HRQOL. Using the combined mortality, depression prevalence and HRQOL estimates, HALE was estimated for the adult population according to depression status and by sex.

RESULTS

For the population of women with a recent major depressive episode, HALE at 20 years of age was 42.0 years (95% CI: 40.2-43.8) compared to 57.0 years (95% CI: 56.8-57.2) for women without a recent major depressive episode. For the population of Canadian men, HALE at 20 was 39.0 years (95% CI: 36.5-41.5) for those with a recent major depressive episode compared to 53.8 years (95% CI: 53.6-54.0) for those without. For the 15.0-year difference in HALE between women with and without depression, 12.3 years can be attributed to the HRQOL gap and the remaining 2.7 years to the mortality gap. The 14.8 fewer years of HALE observed for men with depression equated to a 13.0-year HRQOL gap and a 1.8-year mortality gap.

CONCLUSION

The population of adult men and women with depression in Canada had substantially lower healthy life expectancy than those without depression. Much of this gap is explained by lower levels of HRQOL, but premature mortality also plays a role.

Symptoms of posttraumatic stress, depression, and anxiety as predictors of suicidal ideation among South African university students

OBJECTIVE

To investigate the 2-week prevalence of suicidal ideations and their associations to symptoms of posttraumatic stress, depression, and anxiety among South African university students.

PARTICIPANTS

Data were collected from 1,337 students between May and August 2013.

METHODS

Hierarchical regression analysis was used to investigate the relationship between suicidal ideation and symptoms of posttraumatic stress, depression, and anxiety.

RESULTS

Rates of suicidal ideation are higher among university students in South Africa than among the general population of the country and student populations in other parts of the world. Symptoms of depression and exposure to trauma predict suicidal ideation Conclusions: Findings bring into focus the high rates of suicidal ideation among a sample of university students in South African and the need for more research to investigate the psychosocial correlates of this phenomena within the cultural context of the country, especially given the correlation between suicidal ideation and other poor health outcomes.

Validation of the Korean Version of the Depression Coping Self-Efficacy Scale (DCSES-K)

Coping self-efficacy is regarded as an important indicator of the quality of life and well-being for community-dwelling patients with depression. The Depression Coping Self-Efficacy Scale (DCSES) was designed to measure self-efficacy beliefs related to the ability to perform tasks specific to coping with the symptoms of depression. The purpose of this study was to examine the psychometric properties of a Korean version of the Depression Coping Self-Efficacy Scale (DCSES-K) for community-dwelling patients with depression. A cross-sectional survey design was used. Content and semantic equivalence of the instrument using translation and back-translation of the DCSES was established. A convenience sample of 149 community-dwelling patients with depression was recruited from psychiatric outpatient clinics. The reliability alpha for the DCSES-K was .93, and the internal consistency was found to be acceptable. For convergent validity, DCSES-K score was positively correlated with the General Self-Efficacy Scale (GSES-K) score. For construct validity, significant differences in DCSES-K scores were found between a lower BDI group (mean=73.7, SD=16.54) and a higher BDI group (mean=53.74, SD=16.99) (t=7.19, p<.001). For the DCSES-K, 5 factors were extracted, accounting for 62.7% of the variance. Results of this study suggest that DCSES-K can be used as a reliable and valid measure for examining self-efficacy coping with depression for Korean community-dwelling patients with depression.
