The epidemiology, risk factors, and biological basis of suicidal behaviors have been the object of an ever–increasing research in the last three decades. During this period, researchers all over the world have identified potential biomarkers of risk and developed several theories about the mechanisms leading to suicidal behavior. However, the lack of common terminology, instruments, and cooperation has been a major deterrent. Today, the community has established the bases for this collaboration and evidence coming from neuroscientific studies can already be applied to the field of suicidology. We present here a potential semiology based on current evidence coming from biological, clinical, and neuroimaging studies.Disclosure of interestThe author declares that he has no competing interest.

The World Health Organization <em>Suicide trends in at-risk territories</em> study is a multi-site regional research program operating first in French Polynesia and countries of the Western Pacific, then extended to the world. The aims of the study were to establish a monitoring system for suicidal behaviors and to conduct a randomised control trial intervention for non-fatal suicidal behaviors. The latter part is the purpose of the present article. Over the period 2008-2010, 515 patients were admitted at the Emergency Department of the Centre Hospitalier de Polynésie Française for suicidal behavior. Those then hospitalized in the Psychiatry Emergency Unit were asked to be involved in the study and randomly allocated to either Treatment As Usual (TAU) or TAU plus Brief Intervention and Contact (BIC), which provides a psycho-education session and a follow-up of 9 phone contacts over an 18-months period. One hundred persons were assigned to TAU, while 100 participants were allocated to the BIC group. At the end of the follow-up there were no significant differences between the two groups in terms of number of presentations to the hospital for repeated suicidal behaviors. Although the study could not demonstrate the superiority of a treatment over the other, nevertheless – given its importance – the investigation captured public attention and was able to contribute to the awareness of the need of suicide prevention in French Polynesia. The BIC model of intervention seemed to particularly suit the geographical and health care context of the country.

Abstract Background The economic and human costs of suicide to individuals, families, communities, and society make suicide a major public health problem around the world. Suicide rates in South Korea are among the highest in the world. This paper is the first systematic review investigating socioeconomic risk factors for suicidal behaviors (suicidal ideation, attempted suicides, and completed suicides) in South Korea. Methods We performed a systematic review in Medline and Web of Science. Empirical studies and peer-reviewed articles on the association between individual socioeconomic factors and suicidal behaviors have been included. A total of 53 studies were included in a descriptive synthesis. Results Overall, 35 studies focused on the association between individual socioeconomic factors and suicidal ideation, 16 were related to suicide attempts, while 10 addressed completed suicides. Low income, unemployment, and financial difficulties were identified as risk factors for all suicidal behaviors. Working in precarious conditions, long working hours, self-employment, changes in employment status, shift work/night-time work, and occupational stress were associated with an increased risk for suicidal ideation. Low educational attainment appears to increase the risk for suicide attempts and completed suicide, but the significance of educational attainment on the reporting of suicidal ideation could not be verified. The primary studies were unable to ascertain whether the place of residence impacts on suicidal behaviors. Conclusions The results highlight the relevance of socioeconomic factors for suicidal behaviors in South Korea. Governmental social spending must be increased and redirected more efficiently so that the economically most vulnerable groups are financially protected and income inequality does not widen. Furthermore, comprehensive prevention strategies at the community level are needed. Future research needs to focus on identifying vulnerable groups for whom the effects of low socioeconomic status may have particularly serious consequences with regard to suicidal behaviors.

The epidemiology, risk factors and biological basis of suicidal behaviors have been the object of an ever-increasing research in the last three decades. During this period, researchers all over the world have identified potential biomarkers of risk and developed several theories about the mechanisms leading to suicidal behavior. However, the lack of common terminology, instruments and cooperation has been a major deterrent. Today, the community has established the bases for this collaboration and evidence coming from neuroscientific studies can already be applied to the field of suicidology. We present here a potential semiology based on current evidence coming from biological, clinical and neuroimaging studies. Besides suicidal ideation and warning signs, the clinical features related to suicide risk and revealed by neuroscientific studies include notably: impulsive-aggression and hopelessness as well as high web consumption, sedentary behaviors and reduced sleep time, an enhanced sensibility to social exclusion and loneliness, a decreased sensitivity to detect social support, interpersonal problems related to decision-making impairments, difficulties to regulate negative emotional states, a propensity to perceive psychic and also physical pain and to receive opiates treatments. Improving the assessment will also open new targets for suicide prevention. In the short-term, some of these targets await us: standard protocols for evaluation of risk, healthcare continuity, implication of the family/caregivers, mitigation of social or psychological pain.Disclosure of interestThe author has not supplied his declaration of competing interest.

IntroductionThere is emerging evidence that suicide and suicidal behavior frequently occur in people with autistic spectrum disorders (ASD), although this topic is largely understudied. We have little understanding of suicidal behavior among individuals with ASD and there are no empirical data to guide practitioners in the treatment of suicidality in persons with ASD. There is a need to investigate risk factors associated with suicidal behavior in persons with ASD, to improve prevention strategies and interventions.ObjectivesTo get an overview from literature of risk factors for suicidality in individuals with ASD.MethodsReview of the literature using Cochrane Collaboration Centre, Embase, Medline, PsychINFO, PubMed, and Web of Science.ResultsIn the literature, we found that, among already known risk factors like comorbid depression, an underlying vulnerability in personality may be a risk factor for suicidal behavior. Several studies showed that a high score on the temperament factor ‘novelty seeking’ and ‘harm avoidance’ is associated with suicidality. In other studies, where suicidality was not an object of study, adults with ASD showed high scores on ‘harm avoidance’ and low scores on ‘novelty seeking’. This suggests that personality profiles may be of predictive value for suicidality in adults with ASD. A study proposal focused on this possible association be presented.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionThe aim of the present study was to investigate various risk factors of suicidal behaviors, including the mixed features specifier, in Korean patients with bipolar disorder.MethodsWe retrospectively reviewed medical charts from 2005 to 2014. A total of 334 patients diagnosed with bipolar disorder using the DSM-IV TR were enrolled. Subjects were categorized into two groups according to their history of suicidal behavior and the demographic and clinical characteristics of the groups were compared, including the mixed features specifier. We re-evaluated the index episode using DSM-5 criteria and classified subjects into an index episode with mixed features group and an index episode without mixed features group. Logistic regression was performed to evaluate significant risk factors associated with suicidal behavior.ResultsSuicidal behavior had an independent relationship with mixed features at the index episode using DSM-5 criteria (OR = 3.39; 95% CI: 1.57–7.34) and number of previous depressive episodes (OR = 1.62; 95% CI: 1.34–1.95) in Korean bipolar patients. The mixed feature specifier was the strongest risk factor for suicidal behavior in the present study. Limitations: this was a retrospective study and structured psychiatric interviews were not conducted.ConclusionsThis study may help clinicians understand potential risk factors and manage bipolar disorders with suicidal behaviors. Clinicians should carefully monitor patients with bipolar disorder who exhibit numerous depressive episodes or mixed features for suicidal behavior.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Aim This study examined the trajectory (life course) of youths, referred to community services following their suicidal behavior, in order to measure the extent to which these young people have taken this opportunity to modify connectedness with family, school, and workplace, and to change high-risk factors related to suicidal behaviors (mental health problems, delinquency, drug consumption). Method Fifteen youths (aged 16-19), who made one or more suicide attempts or had serious ideation in the previous 24 to 48 months, were referred to community services (Vallée-Jeunesse). They were interviewed using an intensive personal interview measures (Trajectory Instrument Measure, TIM) in order to document significant life events and adversities that occured during different periods of their life.In addition, we administered the Structured Clinical Interview for DSM-IV Axis-I and Axis-II disorders (SCID-I and SCID-II) to identify past and current psychopathologies. Results Several important changes took place following their entry into the community services: a reduction in delinquency and substance abuse/dependence, and positive changes in occupational status and suicidal behaviors (ideation and suicide attempt). Conclusion Our findings can inform policies and strategies that support the prevention of suicidal behavior among young adults. Community services providers can play a role in the prevention of suicidal behaviors for the most vulnerable youths. These types of services could complement traditional suicide prevention strategies, which are mostly mental-health based.

IntroductionSuicide is one of the main causes of premature mortality in Belarus. It is well recognized that drinking is among the major risk factors that are associated with suicidal behavior.AimsThis study was design to extend our understanding the relationship between alcohol and suicidal behavior.MethodsRisk factors for suicidal behavior (completed suicide and parasuicide) among residents of Minsk city and Gomel city were studied.ResultsAmong the residents of Minsk the maximum suicides risk was in the age of 46–60 years, and parasuicide at age 20–39 years. The ratio of men to women - 4:1; they were often BAC-positive (from 38.8% in 2015 to 42% in 2008). Among parasuicides sex ratio of about 1:1; 30% of men aged 20–39 years, were BAC-positive. Studies in the city of Gomel, has shown maximum number of parasuicides in the ages of 18–29 years (39.3% in women and 30.7% men). Among parasuicides the majority of men (57.8%) and a significant proportion of women (34.2%) were BAC-positive. Maximum number of those attempted suicide and dependent on alcohol were among men ages 30–39 years (66.15%) and 50–59 years (65.22%), among women in the age 30–39 years (45.45%).ConclusionsAcute alcohol intoxication is characteristic of young people who commit parasuicide. Chronic alcohol intoxication is a risk factor in middle-aged persons who commit suicide. Prolonged use of alcohol contributes to the development of comorbid mental disorders, during the crisis of middle age is manifested as an increased risk of suicides.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Background: In studies about the risk factors for suicidal behavior, the assessment of impulsiveness and aggression often depend on information from proxy informants. Aims: To assess the validity of proxy informants’ reports on impulsiveness and aggression in China. Methods: Modified Chinese versions of the Barratt Impulsiveness Scale (BIS-CV) and the Buss-Perry Aggression Questionnaire (AQ-CV) were administered to 131 suicide attempters treated at a hospital in rural China, to coresident relatives about the attempters, to 131 matched community controls, and to coresident relatives about the controls. Results: BIS-CV and AQ-CV total scores and subscale scores were all significantly higher for suicide attempters than for matched controls. Proxy informants considered subjects slightly more impulsive and aggressive than the subjects reported themselves. Subject-proxy concordance for total BIS-CV and AQ-CV scores were excellent for both attempters and controls (ICCs = 0.76–0.83). Concordance for the three BIS-CV subscales was 0.74–0.81 for attempters and 0.74–0.83 for controls. Concordance for the five AQ-CV subscales was 0.66–0.85 for attempters and 0.56–0.82 for controls. Limitations: Results are based on respondents from a single location in rural China. Conclusions: The results support the validity of the BIS-CV and AQ-CV and of research on suicidal behavior in China that uses proxy-based reports of impulsiveness and aggression.

Background: Relatively little is known about the role of protective factors in an Arab population in the presence of suicidal risk factors. Aims: To examine the role of protective factors in a subsample of in large Arab Kindred participants in the presence of suicidal risk factors. Methods: We assessed protective and risk factors in a sample of 64 participants (16 suicidal and 48 nonsuicidal) between 15 and 55 years of age, using a comprehensive structured psychiatric interview, the Composite International Diagnostic Interview (CIDI), self-reported depression, anxiety, hopelessness, impulsivity, hostility, and suicidal behavior in first-degree and second-relatives. We also used the Religiosity Questionnaire and suicide attitude (SUIATT) and multidimensional perceived support scale. Results: Suicidal as opposed to nonsuicidal participants were more likely to have a lifetime history of major depressive disorder (MDD) (68.8% vs. 22.9% χ2 = 11.17, p = .001), an anxiety disorder (87.5% vs. 22.9, χ2 = 21.02, p < .001), or posttraumatic stress disorder (PTSD) (25% vs. 0.0%, Fisher’s, p = .003). Individuals who are otherwise at high risk for suicidality have a much lower risk when they experience higher perceived social support (3.31 ± 1.36 vs. 4.96 ± 1.40, t = 4.10, df = 62, p < .001), and they have the view that suicide is somehow unacceptable (1.83 ± .10 vs. 1.89 ± .07, t = 2.76, df = 60, p = .008). Conclusions: Taken together with other studies, these data suggest that the augmentation of protective factors could play a very important role in the prevention of incidental and recurrent suicidal behavior in Arab populations, where suicidal behavior in increasing rapidly.
