A Qualitative Assessment of Reasons for Living and Dying in the Context of Feeling Trapped Among Adults in the United Kingdom

Objective Contemporary approaches to suicide assessment and treatment incorporate reasons for living (RFL) and reasons for dying (RFD). This study qualitatively explored individuals’ self-described RFL and RFD in the context of suicidal thinking and behaviors. Method Within a community United Kingdom (UK) sample, adults (N = 331, aged 16+) responded to eight open-ended questions probing their experiences of suicide, defeat, and entrapment. Utilizing these data, which were collected from a larger online survey examining risk and protective factors for suicidal behaviors, this study explored RFL and RFD within these narratives. After the research team established an initial code book, RFL and RFD codes were subsequently analyzed through inductive and deductive thematic analyses. Results The present study identified five complimentary RFD-RFL themes: (1) Hopelessness-Hopefulness, (2) Stress of Responsibilities-Duty to Responsibilities, (3) Social Disconnection-Social Connection, (4) Death as Sin-Desire for an Afterlife, and (5) Temporary Escapes as Coping-Entrapment (i.e., a lack of escape). Three subthemes within the RFD theme Entrapment were General/Unspecified, By Feelings, and Within Self. Conclusions Identified themes reflect the existing quantitative RFL and RFD literature. The identified RFL and RFD themes are discussed with reference to their clinical applications in advancing suicide-specific assessments and interventions. We propose a dimensional framework for RFD and RFL which informs future suicidal behaviors research and practice.

Mechanisms of adaptation of the hypothalamic-pituitary-adrenal axis in male mice under chronic social defeat stress

The hypothalamic-pituitary-adrenal axis (HPA) plays an important role in the mechanisms of adaptation to chronic stress. A model of chronic social defeat stress (CSDS), based on the experience of defeat in daily agonistic interactions, causes the development of a depressive-like state in mice, which is often accompanied by an increase in blood corticosterone levels. In this work, we assessed what changes occur in the central (hypothalamus) and peripheral (adrenal glands) parts of the HPA axis under the influence of chronic social stress, which can affect the regulation of corticosterone synthesis and its level in the blood. The experience of chronic social stress causes an increase in the relative weight of the adrenal glands, an increase in the expression level of Crh gene in the hypothalamus and the expression of the genes for the corticosterone synthesis enzymes Star, Cyp11a1, Cyp11b1 in the adrenal glands. At the same time, in the hypothalamus the expression of Fkbp5 and Nr3c1 decreases and the expression of Crhbp increases, and in the adrenal glands the expression of the Mc2r and Hsd11b1 genes decreases, which is ultimately aimed at reducing the amount of corticosterone secreted by the adrenal glands, and thus limiting the glucocorticoid response. Thus, chronic stress leads to an imbalance of the activating and stabilizing mechanisms of HPA axis regulation and a possible inadequate response to additional stress stimuli.

Blood Plasma Markers in Depressed Mice under Chronic Social Defeat Stress.

It has previously been shown that, in mice, chronic social defeat stress in daily agonistic interactions leads to a depression-like state similar to that in depressive patients. With this model, it has become obvious that it is possible to study peripheral markers of the depression-like state in an experiment. This paper was aimed at searching for protein markers in the blood plasma of depressed mice in the chronic social conflict model, which allows for us to obtain male mice with repeated experiences of defeat. Proteomic analysis of blood plasma samples was conducted to identify proteins differentially expressed in this state. There were changes in the expression levels of the amyloid proteins SAA1, SAA4, and SAMP and apolipoproteins APOC3, APOD, and ADIPO in the blood plasma of depressed mice compared with controls (unstressed mice). Changes in the expression of serine protease inhibitors and/or proteins associated with lipid metabolism, inflammation, or immune function [ITIH4, SPA3, A1AT5, HTP (HP), CO9, and A2MG] were also found. Here, we showed that chronic social stress is accompanied by increased levels of amyloid proteins and apolipoproteins in blood plasma. A similarity was noted between the marker protein expression changes in the depressed mice and those in patients with Alzheimer's disease. These data indicate a psychopathogenic role of chronic social stress, which can form a predisposition to neurodegenerative and/or psychoemotional disorders.

M2 macrophage-derived soluble factors enhance neuronal density in the frontal cortex of depression-like mice

IntroductionChronic inflammation in depression is associated with decreased levels of neurotrpohic factors and suppressed neurogenesis. We have previously shown that intranasal therapy with soluble factors from M2 macrophages polarized by interaction with apoptotic cells in serum deprivation conditions (M2(LS); LS - low serum) and characterized by anti-inflammatory and pro-regenerative activity leads to the correction of the behavioral pattern in mice with a depression-like state.ObjectivesThe present study focuses on the effect of M2(LS) macrophages on neuronal density in the frontal cortex and hippocampus of depression-like mice.MethodsDepressive-like state was formed in passive male mice (CBAxC57Bl/6)F1) as a result of repeated experience of defeat in agonistic interactions with aggressive partner during 20 days (the sensory contact model). Depression-like mice were then treated intranasally with M2(LS) macrophages conditioned medium for 7 days. After that, the number of mature neurons in the frontal cortex and hippocampus was assessed using Nissl staining.ResultsThe neuronal density in the pyramidal layer of the frontal cortex was significantly lower in depression-like mice than that in the intact control group of mice (p=0,047). At the same time, the number of neurons in the experimental group of mice that received soluble M2(LS) factors, was higher than that in depressive-like untreated control mice (p=0,003) and was comparable to that in the intact group of mice. At the same time the neuronal density in the CA1 and CA3 hippocampal areas did not change in depression-like mice following intranasal treatment with conditioned medium of M2(LS) macrophages.ConclusionsThe data obtained may indicate the neuroprotective effect of M2(LS) macrophages in the stress-induced depression model, which is realized through soluble factors and manifests itself in an increase of the pyramidal neurons density in the frontal cortex.Disclosure of InterestNone Declared

Psychotic Experiences Questionnaire. Part 1

BACKGROUND: The rationale for the concept of psychotic and psychotic-like experiences, delusions and auditory hallucinations, on the basis of which the Psychotic Experiences Questionnaire was developed.
 AIM: The purpose of this study is to present the results of testing and validating of a questionnaire that assesses the severity of psychotic experiences. The study aims to determine the content of the experience at different phases of manifestation, including the phase of psychotic-like experiences, as well as metacognitive appraisals of the experience and its relationship to social anxiety.
 MATERIAL AND METHODS: The sample of 122 respondents includes non-clinical and two clinical groups — with symptoms of the affective spectrum and with symptoms of the psychotic spectrum. To assess the convergent validity of the Questionnaire, the Russian-language Symptom Check List-90-Revised was used. Metacognitive appraisals of psychotic experience and the overall severity of social anxiety (“Social Anxiety and Social Anxiety Disorder Questionnaire”) were measured.
 RESULTS: The structure of the Questionnaire obtained by cluster analysis was verified by confirmatory factor analysis, and optimal agreement between theoretical and empirical models was demonstrated (CFI=0.998; TLI=0.998; SRMR=0.102; RMSEA=0.02; RMSEA p-value=0.986). Three scales and corresponding subscales (six categories) defining the phases of unfolding of psychotic experience were identified. The high reliability and item consistency of the Questionnaire was determined using Cronbach's alpha coefficient. Convergent validity was assessed using Pearson correlation analysis of the questionnaire scales with the SCL scales — psychoticism, paranoid ideation and obsessive-compulsive symptoms; reliable and adequate statistical relationships were obtained. The role of social anxiety and metacognitive appraisals of psychotic experiences in their actualisation and maintenance is shown. The conceptualisation of thought the emergence of intrusions, “voices” as a dialogical embodiment of the internalised experience of social defeat in re-expanded inner speech is presented.
 CONCLUSION: The results of approbation and validation of the questionnaire are presented, and the relationships of the psychotic experiences component with its metacognitive appraisals and social anxiety are described. The concept of psychotic experiences is considered a continuum in which disruptions in the usual controllability of mental processes vary range from mild (objectification of thinking) — to moderate (disturbance of self-perception, intrusive phenomena, including “voices”) — to severe (disturbance of the sense of agency, including command “voices”).

Behavioural traits related with resilience or vulnerability to the development of cocaine-induced conditioned place preference after exposure of female mice to vicarious social defeat

Exposure to stress induced by intermittent repeated social defeat (IRSD) increases vulnerability to the development of cocaine-induced conditioned place preference (CPP) among male mice; however, some defeated mice are resilient to these effects of stress. In the present study we evaluated the effects of vicarious IRSD (VIRSD) in female mice and explored behavioural traits that are potentially predictive of resilience. C57BL/6 female mice (n = 28) were exposed to VIRSD, which consisted of the animals witnessing a short experience of social defeat by a male mouse on postnatal day (PND) 47, 50, 53 and 56. The control group (n = 10) was not exposed to stress. Blood samples were collected on PND 47 and 56 for corticosterone and interleukin-6 determinations. On PND 57–58, female mice performed several behavioural tests (elevated plus maze, hole-board, object recognition, social interaction, TST and splash tests). Three weeks later, the effects of cocaine (1.5 mg/kg) on the CPP paradigm were assessed. VIRSD decreased corticosterone levels (on PND 56), increased interleukin-6 levels, enhanced novelty-seeking, improved recognition memory and induced anxiety- and depression-like symptoms. Control and VIRSD female mice did not acquire CPP, although some stressed individuals with certain behavioural traits - including a high novelty-seeking profile or the development of depression-like behaviour in the splash test shortly after VIRSD - acquired cocaine CPP. Our results confirm that some behavioural traits of female mice are associated with vulnerability or resilience to the long-term effects of social stress on cocaine reward, as previously observed in males.

OLD UKRAINIAN MYTHOLOGY IN OLEH OLZHYCH’S LYRICS

Ukrainian modernists, in particular Prague School poets, sought to actualize the old Ukrainian mythology in their writings and reinterpret it as a starting point for existence. Relying on the tradition of neoromanticism and neoclassicism, they created a unique style that reflected the experience of defeat in the national liberation war and emigration. This style was an attempt to form a new identity that would maintain continuity with the glorious past and meet the requirements of the time. The poets aimed to establish a new way of thinking that would influence the nation’s worldview, self-determination, and will to struggle. A scrupulous analysis of the elements from old Ukrainian mythology in Oleh Olzhych’s lyrics is crucial for a comprehensive interpretation of his texts. Oleh Olzhych’s poems are saturated with old Ukrainian mythological archetypes, images, and plots that have become a fundamental part of his literary model of the world. The published poems from his books “Pebble” (“Rin”, 1935), “Towers” (“Vezhi”, 1940), and “Pidzamcha” (1946), as well as works beyond these collections, have been analyzed with the use of mythocritical method. Mythologemes, being minimal semantic units of text referring to myths, are typically positioned prominently within the texts.
 The relevant archetypes and images in Oleh Olzhych’s lyrics include the Great Mother, the World Tree, a complex of solar imagery, mediators, and direct references to the gods and creatures of old Ukrainian myths. The old Ukrainian mythology in Oleh Olzhych’s poems accumulates ontological, existential, and value knowledge, appealing to the collective unconscious and being one of the formative components of his worldview.

A qualitative assessment and short-term mediation analysis of defeat, entrapment, and suicide.

The Integrated Motivational-Volitional Model (IMV) of Suicide is growing in empirical support. The present study advances IMV research through two aims: (1) to qualitatively probe the subjective experiences of defeat, internal entrapment, and external entrapment, and (2) conducting a 3-month prospective mediation analysis using quantitative and qualitative metrics of defeat and entrapment. The study featured an online two-point survey separated by 3 months. Participants were 255 adults living in the United Kingdom. Persons endorsing qualitative defeat and internal entrapment in their narratives also showed higher quantitative scores on corresponding IMV and suicide-related self-report scales. Internal entrapment mediated the effect of baseline defeat on 3-month suicidal ideation, whereas external entrapment mediated the association of baseline defeat on 3-month suicide attempt likelihood. Quantitative assessment of entrapment was more significantly associated with suicide attempts and ideation within mediation tests compared to corresponding qualitative variables. IMV model principles are largely supported by findings. Mediation results support further consideration of entrapment and defeat within clinical practice and public health-focused suicide research. Understanding the complexity of entrapment narratives represents an important next step for conducting qualitative IMV-focused research with minoritized and high-risk suicide populations.

Acetylcholine potentiates glutamate transmission from the habenula to the interpeduncular nucleus in losers of social conflict

Switching behaviors from aggression to submission in losers at the end of conspecific social fighting is essential to avoid serious injury or death. We have previously shown that the experience of defeat induces a loser-specific potentiation in the habenula (Hb)-interpeduncular nucleus (IPN) and show here that this is induced by acetylcholine. Calcium imaging and electrophysiological recording using acute brain slices from winners and losers of fighting behavior in zebrafish revealed that the ventral IPN (vIPN) dominates over the dorsal IPN in the neural response to Hb stimulation in losers. We also show that GluA1 α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunits on the postsynaptic membrane increased in the vIPN of losers. Furthermore, these loser-specific neural properties disappeared in the presence of an α7 nicotinic acetylcholine receptor (nAChR) antagonist and, conversely, were induced in brain slices of winners treated with α7 nAChR agonists. These data suggest that acetylcholine released from Hb terminals in the vIPN induces activation of α7 nAChR followed by an increase in postsynaptic membrane GluA1. This results in an increase in active synapses on postsynaptic neurons, resulting in the potentiation of neurotransmissions to the vIPN. This acetylcholine-induced neuromodulation could be the neural foundation for behavioral switching in losers. Our results could increase our understanding of the mechanisms of various mood disorders such as social anxiety disorder and social withdrawal.

Chronic social defeat alters behaviors and neuronal activation in the brain of female Mongolian gerbils

Chronic social defeat has been found to be stressful and to affect many aspects of the brain and behaviors in males. However, relatively little is known about its effects on females. In the present study, we examined the effects of repeated social defeat on social approach and anxiety-like behaviors as well as the neuronal activation in the brain of sexually naïve female Mongolian gerbils (Meriones unguiculatus). Our data indicate that repeated social defeats for 20 days reduced social approach and social investigation, but increased risk assessment or vigilance to an unfamiliar conspecific. Such social defeat experience also increased anxiety-like behavior and reduced locomotor activity. Using ΔFosB-immunoreactive (ΔFosB-ir) staining as a marker of neuronal activation in the brain, we found significant elevations by social defeat experience in the density of ΔFosB-ir stained neurons in several brain regions, including the prelimbic (PL) and infralimbic (IL) subnuclei of the prefrontal cortex (PFC), CA1 subfields (CA1) of the hippocampus, central subnuclei of the amygdala (CeA), the paraventricular nucleus (PVN), dorsomedial nucleus (DMH), and ventrolateral subdivision of the ventromedial nucleus (VMHvl) of the hypothalamus. As these brain regions have been implicated in social behaviors and stress responses, our data suggest that the specific patterns of neuronal activation in the brain may relate to the altered social and anxiety-like behaviors following chronic social defeat in female Mongolian gerbils.

Spillover effects of competition outcome on future risky cooperation

There is growing evidence that risky cooperation is regulated by the experience of previous interactions with others. However, it is unclear how the evaluation of outcomes from competitive interactions can affect individuals’ subsequent cooperative behavior. To address this issue, we examined how participants cooperated with a partner having just competed with them. While competing, participants (N = 164) were randomly assigned to receive one of four types of outcome feedback regarding their performance (victory vs. defeat vs. uncertain vs. no competition (control)). We found that both the experience of defeats and of uncertainty as competitive outcomes exerted a negative impact on the extent to which participants then engaged in cooperative behavior with their recent opponents. This only occurred when such subsequent cooperative behavior involved a high potential for incurring personal costs but not when there was no risk of incurring personal costs and a positive return. Finally, mediation analysis revealed that the effect of defeat was mediated by participants’ level of interpersonal trust and the extent to which participants were willing to cooperate, while the effect of the uncertain competitive outcome was mediated only by the extent to which participants were willing to cooperate. These findings offer novel insights into how risky cooperation is modulated by previous competition.

The Role of Social Defeat in Neurological differences in Psychotic Patients

IntroductionThe social defeat hypothesis (SDH) suggests that a chronic experience of social defeat increases the likelihood of the development of psychosis. The SDH indicates that a negative experience of exclusion leads to an increase in the baseline activity of the mesolimbic dopamine system (MDS), which in turn leads to the onset of psychosis. Social defeat models have previously been produced using animal models and preclinical literature; however, these theories have not fully been tested in human clinical samples. There have been studies implying changes in brain structure due to social defeat interactions; however, research evidence is varied.ObjectivesThis study aims to uncover whether exposure to SoDe has an impact on brain structure. Furthermore, we hope to understand if these changes are relevant to other mental health disorders.Methods698 (506 no SoDe, 191 SoDe) participants between the ages of 15-41 were recruited from the PRONIA-FP7 study. SoDe was measured from the self-reported questionnaires’ Bullying Scale’ and ‘The Everyday Discrimination Scale’. T1-weighted structural MRI data were processed; five 2 sample t-test analyses were carried out to compare the GMV differences in the entire sample and between the four groups.ResultsThe VBM analysis showed significant group interactions in the right thalamus proper when comparing participants who had experience SoDe to participants who had not experienced SoDe including all 4 groups along with left cerebral white matter differences. In the ROP subgroup, significant group interactions in the left cerebellum white matter were found along with right cerebral white matter, left cerebral white matter and right Thalamus proper.ConclusionsThe findings suggest that there are significant group interactions in thalamus and cerebral white matter. This is in keeping with some previous research suggesting volumetric changes in the thalamus due to stress and psychosis. Similarly for white matter there is some evidence suggesting differences due to SoDe and psychosis. However, there is a scarcity of research in this area with different research suggesting distinctive findings and therefore the evidence is inconclusive. In the ROP group analysis significant group interactions were present in the cerebellum due to SoDe experience. There is research suggesting the cerebellum’s role in multiple different aspects like social interaction, higher-order cognition, working memory, cognitive flexibility, and psychotic symptoms, with every research suggesting multiple different things the role of the cerebellum in SoDe in the ROP population is in question. Nonetheless this large-scale research presents some interesting novel finding and leads the way to a new area of research. Further analysis will explore the relationship between groups on markers of stress (CRP) and neuroinflammation as potential mediation of the environmental effects of SoDe.Disclosure of InterestNone Declared

Migration, perceived discrimination and the development of psychosis

IntroductionMigration is a rapidly growing phenomenon in European countries and its association with psychotic disorders is a public health concern. Psychosis is more prevalent among migrants, which suggests that adverse social experiences play an important role in its pathogenesis. Throughout the migration process, migrants are exposed to several social disadvantages, including in the post-immigration context, where perceived discrimination appears to be an important stressor. In fact, the highest incidence rates of psychosis occur in the most discriminated populations, namely migrants with darker skin complexion, particularly when living in low-ethnic-density neighborhoods, where both discrimination and social isolation are more prominent.ObjectivesTo conduct an updated review about the association between migration, perceived discrimination and psychosis, aiming to better understand the mechanisms involved.MethodsNarrative literature review using the keywords “migration”; “psychosis”; “discrimination”; “racism” on PubMed database, in conjunction with presentation of a clinical case concerning a patient from Guinea-Bissau, admitted to our hospital in the context of first-episode psychosis (FEP), with onset months after completing the Mediterranean migration route to Europe.ResultsLiterature suggests that experiences of racism and social exclusion contribute to feelings of imminent danger, fear and general anxiety, which may develop into paranoid ideas of ubiquitous persecution. Furthermore, intense social defeat experiences, common in migrants, are associated with more distressing forms of delusional content, with delusions of psychological persecution being more common. However, there is also evidence that migrants with FEP have better occupational and social functioning profiles compared to natives, suggesting that, in these patients, there is a higher burden of social-environmental risk factors, with the onset of psychosis occurring only when this burden overcomes a higher threshold. Our patient fits this description. After completing his migratory route and while living in an Italian refugee camp, he described suffering experiences of severe discrimination. Real or not, these experiences escalated to become delusional ideas of persecution involving European governments, thought to seek for his humiliation. Despite the presence of psychotic symptoms, this patient was able to maintain a reasonable level of functioning during years, up to his psychiatric admission.ConclusionsGiven the notorious effect of perceived discrimination and racism on the increased risk of psychosis in immigrants, it is urgent to adopt policies that promote the social protection of these vulnerable groups, namely through enhancing their integration in the host countries.Disclosure of InterestNone Declared

Resistance in Postwar France: Five New and Noteworthy Histories

Historians of modern Europe have long seen the tragic events of the Second World War in France as a major caesura in the history of that nation. But eighty years later, do the legacies of the war still help us understand postwar France and its political divisions? The five superb books under review make a strong case that the fracturing experiences of defeat, Vichy and the Resistance shaped some of the most important subsequent developments in France in ways that previous historians have failed to recognise. The developments identified by these authors include the waxing and waning of Resistance myths as part of a contested deportation memory landscape, an anti-authoritarian résistant psychiatry born in 1940 that went on to revolutionise French theories of alienation in the face of both Stalinism and postwar capitalism, and rural resistance to the state-led transformation of the countryside as part of France's postwar economic modernisation. Collectively they point to a larger takeaway for historians of postwar Europe: oppositional movements in France may resemble similar movements elsewhere in a Western context marked by Cold War tensions and, more recently, globalisation; but these protests are also always following a script haunted in part by the trauma of France's war years – a past that has not passed, even eight decades later.

Resilience to the effects of social stress on vulnerability to developing drug addiction

We review the still scarce but growing literature on resilience to the effects of social stress on the rewarding properties of drugs of abuse. We define the concept of resilience and how it is applied to the field of drug addiction research. We also describe the internal and external protective factors associated with resilience, such as individual behavioral traits and social support. We then explain the physiological response to stress and how it is modulated by resilience factors. In the subsequent section, we describe the animal models commonly used in the study of resilience to social stress, and we focus on the effects of chronic social defeat (SD), a kind of stress induced by repeated experience of defeat in an agonistic encounter, on different animal behaviors (depression- and anxiety-like behavior, cognitive impairment and addiction-like symptoms). We then summarize the current knowledge on the neurobiological substrates of resilience derived from studies of resilience to the effects of chronic SD stress on depression- and anxiety-related behaviors in rodents. Finally, we focus on the limited studies carried out to explore resilience to the effects of SD stress on the rewarding properties of drugs of abuse, describing the current state of knowledge and suggesting future research directions.

Patience, Suffering, and Tolerance: The Experience of Defeat and Exile among the Jesuits of Ethiopia (1632–59)

Abstract This article explores the last letters written by the Catholic patriarch of Ethiopia in exile Afonso Mendes, which illustrate that, in the face of defeat, Mendes has chosen to write the history of martyrdom, the sacrifice, and shedding of blood for the sake of faith. A group requires a sense of connection through a temporary axis. Mendes’s choice in these last years corresponds to the will of generating cohesion in space and continuity in time in a group that has confronted rupture, disillusionment, and deterioration. Mendes might have attempted to establish a framework that would allow him to alleviate the tension caused by the clash between the original aspirations and the flawed fulfillment of the objective. Therefore, the redaction of the processes of martyrdom and the creation of a calendar allows the transition into a place where a harmonious relationship between the past and the present is generated.

Examining the protective function of perceptions of post-traumatic growth against entrapment and suicidal ideation

BackgroundRecent evidence has found that reporting post-traumatic growth (PTG) from a past stressful life event is associated with lower reports of suicidal ideation. Perceptions of PTG measure the extent to which an individual reports positive changes in their identity, relationships, and worldviews after a stressful event. However, little is known about how perceptions of PTG interact with feelings of defeat and entrapment to influence suicidal ideation. The current study examined this question through the Integrated Motivational-Volitional (IMV) Model of Suicidal Behavior. Methods521 adult participants (315 females with age range of 18–82, M = 30.4 years, SD = 13.6) completed an online cross-sectional questionnaire with defeat, entrapment, suicidal ideation, PTG, depression and anxiety measures. Hypotheses and data analysis plans were pre-registered prior to data collection. ResultsPTG negatively correlated with defeat, entrapment and suicidal ideation. PTG predicted lower suicidal ideation when controlling for entrapment, depression and anxiety. PTG did not moderate the relationship between defeat on entrapment or the relationship between entrapment on suicidal ideation. LimitationsThe findings were based on cross-sectional data where participants recalled experiences of defeat, entrapment and suicidal ideation from the past year. The sample was a large community (non-clinical) sample, and most of the participants identified as white (85%). ConclusionAlthough PTG did not function as a moderator within the IMV model of suicidality, it predicted lower suicidal ideation while controlling for other known predictors of suicidal ideation.Future research could explore the function of PTG in appraisal-based models of suicidality.

Sports competition related anxiety: Is it modifiable among athletes in urban schools in Sri Lanka?

Competition related anxiety is a major psychological issue among athletes and this study estimates the prevalence of competition related anxiety, its associated factors and coping strategies used, among school athletes in Sri Lanka. A cross-sectional study was conducted among 330 athletes. Two-stage simple random sampling was used. Competition related anxiety level was determined by Sport Competition Anxiety Test for adults (SCAT-A). Prevalence of ‘high’ level of sport competition related anxiety was 19.4% and it was significantly associated with individual sports, fear of failure, experience of past defeat, and poor support received from parents/friends. Listening to music, goal setting, positive self-talk and meditation were positive coping strategies used by athletes. The main negative coping strategy was being angry. High competition related anxiety prevalent in about 1/5th of school athletes was influenced by several factors related to the sport event. Psychological support incorporated into routine physical training sessions is recommended.

Exploring the associations between dimensions of schizotypy and social defeat

ABSTRACT Background This study investigated relationships between self-reported experiences of social defeat and individual dimensions of self-reported schizotypy. Methods 1632 adults aged between 18 and 79 participated across two non-clinical samples (n = 920, n = 712). Multiple regression analyses tested the relationships between dimensions of schizotypy and social defeat. Results The analyses demonstrated evidence of relationships between increased overall schizotypy and increased social defeat, with schizotypal suspiciousness and disorganised or constrained thought and speech consistently emerging as the two most important individual predictors. Conclusion These results suggest that increased schizotypy is associated with increased social defeat, although the specific relationships may depend on the specific aspects of social defeat and schizotypy being measured. Future research should investigate whether social defeat plays a role in the manifestation of specific schizotypy traits.

Increased rates of social defeat and schizotypy in racial minorities

This study examines the extent to which a measure of multidimensional schizotypy is associated with experiences of social defeat. Based on the social defeat hypothesis of psychosis, which suggests that chronic stressful experiences leading to social defeat increase risk for psychotic-like experiences, we expect that individual differences on a schizotypy measure would be explained by differences in social defeat. We hypothesized that racial and ethnic minorities would report higher rates of schizotypy relative to non-minorities and that social defeat would explain those differences. Participants included a community sample of English-speaking adults ages 18 and older, recruited from online social media platforms (N = 501; M age = 28.06). Demographic information was collected, as well as the Multidimensional Schizotypy Scale–Brief (Kwapil et al., 2018) and the Defeat Scale (Gilbert & Allan, 1998). Analyses revealed that social defeat and schizotypy scores are highly correlated. Examination of group differences revealed that racial and ethnic minorities reported higher rates of schizotypy and higher rates of social defeat than non-minorities. ANCOVA analyses revealed that, after controlling for social defeat scores, racial and ethnic status was no longer significantly associated with schizotypy scores.
