Active clinical trials for "Suicide"

Suicide is a major health problem that causes annually a million death worlwide. In the stress-vulnerability model, suicidal behavior (SB) results from the interaction between an individual's predisposition (personality, family history of SB…) and stressful conditions (early life adversity). Studies show that suicide ideations could favour inflammation and that depression is associated with an elevated inflammation. Recent evidences also suggest that inflammatory mediators play a critical role in SB. The aim of the study is to evaluate the inflammatory markers rate on depressed patients with or without personal history of SB. In the second part of the study, the relations between the rates of inflammatory markers and characteristics of SB, impulsivity, psychological pain, childhood abuse and gene expression of 5HT2B receptor will be investigated.

Compared to a treatment-as-usual group, providing brief mental health education to suicide attempters from rural parts of China at the time of their treatment in the emergency departments of general hospitals or local clinics and 6 home-visits (FOR those subjects WITH PHONES refuse home visits, THE INTERVIEWS WILL BE CONDUCTED OVER THE PHONE) over the twelve months after the attempt demonstrate continuing concern about the attempters ('befriending'), strengthen their social support networks and improve their problem-solving skills will significantly reduce their hopelessness, the severity of depressive symptoms, and level of suicidal ideation.

The role of impulsivity and its contribution to suicidal behavior seems intuitively clear. Empirical results have proved the existence of a relationship between the two yet many questions are left unanswered, especially what differentiates suicide ideators from attempters.. Obsessive thinking patterns are thought processes which share a repetitive behavior domain and are exerted by an inner voice. 3 types of obsessive thinking patterns are self destructive thoughts, ruminations and overvalued ideas. Impulsivity and obsessive thinking patterns are presumed to have a common mechanism of behaviors which are resulted from basal ganglia dysregulation and thus effect inhibition. Novel research in the field of decision making could help to learn more about behavioral patterns associated with self harm behavior and suicide. Eating Disorders involve suicidal and self harm behavior, which both feature impulsivity and obsessive thinking patterns. The investigators study proposes a 3-step theoretical model which asserts there is a connection between impulsivity, obsessive thinking and poor decision making, all effecting self harm behavior. Contemporary research has not been able to fully understand the nature of impulsivity and its effect on self harm behavior, including eating disorders symptoms, nor addressed the impact of obsessive thinking patterns on the latter. 100 female participants with Eating Disorders and suicidal behavior will be recruited for the proposed research. Subjects will be given self-report questionnaires and computerized behavioral tasks. A one way ANOVA of two eating disorder subgroups, impulsive and non impulsive, will be conducted, following a hierarchical multiple regression with self harm behavior being the dependent variable.

The goal of the Alaska Native Resilience Research Study (ANRRS) is to identify community-level protective factors that can most effectively reduce co-occurring youth suicide and alcohol risk. The following specific aims will help us achieve this overarching goal. The research team will: (1): Assess the association of a set of modifiable cultural, community and institutional factors (protective community factors) with suicide, suicidal behaviors (ideation, attempt), and associated adverse outcomes (accidental death, alcohol-misuse requiring healthcare) in 64 rural and remote Alaska Native villages to identify community-level factors that are most predictive of youth health outcomes; (2): In a stratified random sample of six communities, use quantitative methods to test a multi-level model of individual-level youth protective factors as predictors of individual-level youth resilience from suicide risk outcomes; and (3): Develop and disseminate a method-Alaska Community Resilience Mapping (AK-CRM)-for communities to measure and strategically strengthen their protective capabilities to increase youth health and reduce the risk for suicide. Methodology:

Promising results have shown that interventions to reduce insomnia diminish suicidal ideation. A better understanding of the bidirectional mechanism between sleep disturbances and suicide behavior will allow the design of tailored interventions to prevent suicide attempts. Significance of the proposed study for the field The aim of the present is to assess the feasibility and the acceptability of sleep tracking monitoring in a sample of suicide attempters. The investigator hypothesize that sleep monitoring using a connected object is feasable and acceptable by patients.

Suicide is the act of killing oneself and accounts for one death every 40 seconds around the world. In the UK, over 75% of suicides are completed by men. Suicidal ideation is a symptom of depression and is assessed when diagnosing depressive disorder. Men are three times more likely to complete suicide than women but half as likely to be diagnosed with depression, and therefore risk missing out on potentially lifesaving treatments. Men experiencing depression and associated suicidality are less likely to demonstrate traditional symptoms such as hopelessness and sadness, and more likely to engage in unhelpful coping strategies such as avoidance through over-working, substance misuse, or risk-taking behaviours, and may feel that they have lost control. Previous research has shown a link between rumination and increased suicidal intent. Unhelpful coping strategies, distorted beliefs about uncontrollability, and thinking processes such as rumination, are central to the metacognitive model of psychological distress and are targeted in Metacognitive Therapy (MCT). The aim of this project is to identify if any aspects of the thinking styles described above are present in a sample of men who are suicidal. The project will also explore beliefs about masculinity and how these beliefs might impact help-seeking. In order to achieve these aims, 15 male service-users without a severe and enduring mental illness, who are receiving care from the Home Based Treatment Team following suicidal thoughts or actions, will be invited to take complete some questionnaires and partake in an interview.

The primary purpose of the current study is to rigorously test the psychometric properties of the INQ-12 and ACSS (Van Orden et al., 2008) in Veterans, something which has not been done to date. Factor structure, internal consistency, convergent and discriminant validity will all be assessed. Secondary goals are to determine if burdensomeness, failed belongingness, and acquired capability are distinct versus overlapping constructs and whether or not values mediate the relationship between reasons for living and suicide risk. Lastly, the inclusion of the Beck Scale for Suicidal Ideation (BSS) allows us to analyze participants' responses to explore whether or not participants can be grouped into those who want to die by suicide because they want to escape their problems and those who want to die to influence other people.

This research tries to investigate the validity and reliability of eye-tracking technologies by using different paradigms (eg. free-view, pro-saccade and anti-saccade) which served as a novel way of evaluating suicide risk among affective disorder patients including bipolar and unipolar depression. All the participants including health control will be assessed by clinical interviewing, self-report assessment, cognitive evaluation and eye-tracking task.

This study is an observational study, without intervention. Using a tablet application that developed for this study. In addition, sensors are used to examine the possibility of using the system to assess the risk of suicide. It should be noted that this is a pilot study, only for a wider study involving a larger number of patients. The system developed for the benefit of this study is based on a smartphone application installed on a standard Smartphone device that will be found in the ED or by the examiner. The system collects data from five channels one by one (the information collected from each channel is collected separately). The data recorded from the various channels is saved on the tablet device. Then, the information transferred to the database using a cable. A statistical analysis of the data from the various channels is carried out in order to assess suicidal behavior. After the statistical analysis, correlations will be examining between the results of the measurements and the results of the accepted questionnaires for the assessment of suicidality, which will be performed simultaneously. Note that the duration of participation is the duration of the measurements, ie a single session that lasts up to two hours The duration of the participants in the study is determined by the time of the measurements, ie a single session lasting up to two hours.

The aftermath of suicide is devastating, being the cause of 800 000 deaths every year worldwide. In France, suicide still causes about 10 000 deaths per year and the number of suicide attempts (SA) is estimated between 170 000 and 200 000 per year (InVS). It is often thought that a suicidal crisis is only related to depression, as it actually is a far more complex phenomenon. A suicidal crisis can occur on various grounds like psychiatric disorders but also contextual events or somatic diseases and it has been hypothesized that suicidal ideas or inclinations could have a common and independent cognitive origin
