Article
Full-text available
A wealth of research suggests that sexual minority individuals experience stigma and lack of sexual minority specific competencies in mental health care, which could lead to less optimal treatment outcome. However, most related research suffers from methodological limitations, such as selected samples, retrospective design, or not assessing treatme...
Article
Background: Some authors claimed that the US Food and Drug Administration (FDA) black box warning on treatment-emergent suicidality with antidepressants in adolescents (issued 2004) and young adults (issued 2006) led to an increase of suicides, based on the analyses of ecological data with debatable assumptions about putative changes in suicide rat...
Article
Full-text available
Background: Suicide rates vary with important cycles in life, according to scientific findings and sometimes only according to lay beliefs. This paper reviews empirical studies on the association between suicides and a selection of cycles in life (the course of day, week, year, and life, menstrual cycle, and the moon phases). Methods: Non-system...

Background Young lesbian, gay, bisexual, transgender, queer as well as other sexual/gender minorities (LGBTQ+) persons have higher rates of suicidal ideation and behavior compared to their non-LGBTQ+ peers, particularly during their coming out. The “It Gets Better” project is a multi-national media campaign that aims to reduce suicide among LGBTQ+...
Article
Full-text available
Background: Ecological studies have explored associations between suicide rates and antidepressant prescriptions in the population, but most of them are limited as they analyzed short-term correlations that may be spurious. The aim of this long-term study was to examine whether trends in suicide rates changed in three European countries when the fi...

This paper is a response to the study of Meyer-Rochow et al. (2020), who found a statistically significant increase of suicides during full moon among women in the region of Oulu, Finland. We argue that this may be a false-positive finding because of subgroups not specified a-priori and the many negative previous findings. Furthermore, we could not...
Article
Background: In antidepressant trials for pediatric patients with depression or anxiety disorders, the risk of suicidal events and other severe psychiatric adverse events such as aggression and agitation is increased with antidepressants relative to placebo. Objective: To examine whether largely mentally healthy adolescents treated for a non-psyc...

Several suicidologists have suggested modeling suicidal processes within the framework of nonlinear dynamic systems (NDS). In this chapter, we summarize our NDS perspective on suicidal processes, developed in cooperation with Günter Schiepek. This includes the application of basic concepts of NDS for suicidal processes, followed by a discussion of...

Background: Past studies have repeatedly shown higher suicidal thoughts and attempts among sexual minority members, yet have remained opaque on whether these groups are more prone to taking their own lives. Aims: This short report focuses on suicide deaths among sexual minority members. Method: We utilized two large-scale surveys: one, among adults...
Article
Osler and colleagues published a cohort study investigating antidepressant medication and suicidal behaviour and violent crime in patients and conscripts (1). They report an increased incidence rate for both events before and after treatment initiation when compared to the follow‐up period. They conclude that there is likely no causal effect of ant...
Article
Full-text available
Several international guidelines for the acute treatment of moderate to severe unipolar depression recommend a first-line treatment with antidepressants (AD). This is based on the assumption that AD obviously outperform placebo, at least in the case of severe depression. The efficacy of AD for severe depression can only be definitely clarified with...
Article
Full-text available
Objective: Religion and spirituality (R&S) were protective against suicidal behavior in the majority of studies. In prospective studies, R&S were associated with improved outcome for patients with depression, a main risk factor for suicide. Thus, R&S may also improve recovery from suicidal crisis, but related data is lacking. Method: We explored...

Following the publication of a recent meta-analysis by Cipriani et al. (1), various opinion leaders and news reports claimed that the effectiveness of antidepressants has been definitely proven (2). E.g., Dr. Pariante, spokesperson for the Royal College of Psychiatrists, stated that this study “finally puts to bed the controversy on antidepressants...
Article
Multiple epidemiologic studies demonstrate a disparity in suicide risk between sexual minority (lesbian, gay, bisexual) and heterosexual populations; however, both 'exposure' (sexual minority status) and outcome (suicide attempts) may be affected by information bias related to errors in self-reporting. We therefore applied a Bayesian misclassificat...

Full-text available
Antidepressant drugs are the mainstay of depression treatment in both primary and specialized mental health care. However, academic psychiatry holds false beliefs about antidepressants and we expose two of them in this essay. First, recent attitude surveys conducted among psychiatrists and general practitioners have revealed that physicians attribu...

Full-text available
Most studies have found religion/spirituality to be protective against suicide risk, with a stronger effect among women. To understand this effect, theories of suicide and clinical samples are needed, but related studies are lacking. We applied two established suicide models in 753 psychiatric inpatients. Religion/spirituality correlated protective...

Gay men are at higher risk of suicidality. This paper describes the causes of suicide attempts as perceived by the men themselves and analyzes their impact on severity and recidivism. Mental health surveys conducted among gay men in Geneva, Switzerland, from two probability-based time-space samples in 2007 and 2011, were merged to yield a combined...
Article
Background: Contrary to the myth that suicides increase around Christmas, multiple studies reveal that suicide rates decrease towards Christmas and return back to normal or even peak in the beginning of the new year. We aimed to replicate this effect for Austria. Methods: The analyses were based on the official suicide statistics 2000-13 using P...
Article
Introduction Early studies showed an increased risk for suicide among non-heterosexual individuals, when compared to exclusively heterosexual individuals. Non-heterosexual individuals are often subsumed under the term “sexual minorities” and cover a wide range of subgroups, such lesbian, gay, bisexual, or questioning individuals, men who have sex w...

Aim. The human body's ability to sense positions of body parts in the three dimensional space is defined as the joint position sense (JPS). Worsening of JPS due to acute local fatigue in e.g. shoulder joints coincides with a decline of handball specific abilities such as throwing accuracy. The purpose of our study was to determine the influence of...

Full-text available
Despite decades of research, the prediction of suicidal behavior remains limited. As a result, searching for more specific risk factors and testing their predictive power are central in suicidology. This strategy may be of limited value because it assumes linearity to the suicidal process that is most likely nonlinear by nature and which can be mor...

The validity of self-reported suicide attempt information is undermined by false positives (e.g., incidences without intent to die), or by unreported suicide attempts, referred to as false negatives. In a sample of 1,385 Austrian adults, we explored the occurrence of false positives and false negatives with detailed, probing questions. Removing fal...

Previous studies indicate that homosexual or bisexual individuals are at a higher risk of attempting suicide compared to heterosexuals. To overcome biases in these studies, more rigorous definitions of "suicide attempts" and the assessment of multiple dimensions of sexual orientation are needed. In addition, studies from the German speaking region...
