RÉSUMÉ

BACKGROUND: During the COVID-19 pandemic, social-distancing and confinement measures were implemented. These may affect the mental health of patients with mental disorders such as schizophrenia. This study examined the clinical course of patients with schizophrenia at a public hospital in Morocco during the COVID-19 pandemic. METHODS: This longitudinal observational study was conducted across three periods in 15 months: 1 April 2020 (start of strict home confinement) to 30 June 2020 (T1), 1 July 2020 to 31 January 2021 (corresponding to the Delta wave) [T2], and 1 February 2021 to 30 June 2021 (corresponding to the Omicron wave) [T3]. Patients aged 18 to 65 years with a diagnosis of schizophrenia or schizoaffective disorder (based on DSM 5) made before the pandemic who presented to the Faculty of Medicine and Pharmacy of Rabat were invited to participate. Psychotic symptomatology was evaluated using the Positive and Negative Syndrome Scale (PANSS). Severity and improvement of mental disorder were evaluated using the Clinical Global Impression (CGI)-Severity and -Improvement subscales. Depressive symptoms were assessed using the Calgary Depression Scale (CDS). Adherence to treatments was assessed using the Medication Adherence Rating Scale (MARS). All assessments were made by psychiatrists or residents face-to-face (for T1) or via telephone (for T2 and T3). RESULTS: Of 146 patients recruited, 83 men and 19 women (mean age, 39 years) completed all three assessments. The CGI-Severity score was higher at T2 than T1 and T3 (3.24 vs 3.04 vs 3.08, p = 0.041), and the MARS score was higher at T1 and T2 than T3 (6.80 vs 6.83 vs 6.35, p = 0.033). Patient age was negatively correlated with CDS scores for depressive symptoms at T1 (Spearman's rho = -0.239, p = 0.016) and at T2 (Spearman's rho = -0.231, p = 0.019). The MARS score for adherence was higher in female than male patients at T1 (p = 0.809), T2 (p = 0.353), and T3 (p = 0.004). Daily tobacco consumption was associated with the PANSS total score at T3 (p = 0.005), the CGI-Severity score at T3 (p = 0.021), and the MARS score at T3 (p = 0.002). Patients with a history of attempted suicide had higher CDS scores than those without such a history at T1 (p = 0.015) and T3 (p = 0.018) but not at T2 (p = 0.346). CONCLUSION: Home confinement during the COVID-19 pandemic had limited negative impact on the mental health of patients with schizophrenia in Morocco.

RÉSUMÉ

BACKGROUND: In recent years, a growing body of evidence has demonstrated the efficacy of non-pharmacological interventions for schizophrenia spectrum disorders (SSD) including positive symptoms such as auditory hallucinations (AH). However, clinical trials predominantly examine general treatment effects for positive symptoms. Therefore, previous research is lacking in comprehensive and clear evidence about psychological and psychosocial approaches that are primarily tailored to treat AH. To overcome this knowledge gap in the current literature, we will conduct a systematic review and meta-analysis to assess the efficacy of clearly targeted psychological and psychosocial interventions for AH in persons with SSD. METHODS AND ANALYSIS: This study protocol has been developed according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols. We will include all randomized controlled trials analyzing the efficacy of targeted psychological and psychosocial interventions especially aimed at treating AH in SSD. We will include studies on adult patients with SSD experiencing AH. The primary outcome will be the change on a published rating scale measuring AH. Secondary outcomes will be delusions, overall symptoms, negative symptoms, depression, social functioning, quality of life, and acceptability (drop-out). We will search relevant databases and the reference lists of included literature. The study selection process will be conducted by two independent reviewers. We will conduct a random-effect meta-analysis to consider heterogeneity across studies. Analyses will be carried out by software packages in R. The risk of bias in each study will be evaluated using the Cochrane Risk of Bias tool. Assessment of heterogeneity and sensitivity analysis will be conducted. DISCUSSION: The proposed study will augment the existing evidence by providing an overview of effective treatment approaches and their overall efficacy at treating AH in SSD. These findings will complement existing evidence that may impact future treatment implementations in clinical practice by addressing effective strategies to treat AH and therefore improve outcomes for the addressed population. ETHICS AND DISSEMINATION: No ethical issues are foreseen. We will publish the results from this study in peer-reviewed journals and at relevant scientific conferences. TRIAL REGISTRATION: PROSPERO registration number: CRD42023475704.

RÉSUMÉ

INTRODUCTION: Auditory-verbal hallucinatory experiences (AVH) have a 12% prevalence in the general pediatric population. Literature reports a higher risk of developing AVH in post-traumatic stress disorder (PTSD). The persistence of AVHs during adolescence represents a risk of evolution into psychotic disorders. Social cognition and emotional markers could be considered prodromes markers of this evolution. The objectives of this prospective observational study are to observe social cognition and emotional markers correlation with the presence and persistence of AVH over two years and with the evolution of PTSD and psychotic diagnosis. METHODS AND ANALYSIS: This prospective case-control study, longitudinal over two years (with an interim reassessment at six months and one year), will include 40 participants aged 8 to 16 years old with a diagnosis of PTSD and without a diagnosis of psychosis according to the criteria of DSM-5 (K-SADS-PL). Subjects included are divided into two groups with AVH and without AVH matched by gender, age and diagnosis. The primary outcome measure will be the correlation between social cognition and emotional makers and the presence of AVH in the PTSD pediatric population without psychotic disorders. The social cognition marker is assessed with the NEPSY II test. The emotional marker is assessed with the Differential Emotion Scale IV and the Revised Beliefs About Voices Questionnaire. The secondary outcome measures are the correlation of these markers with the persistence of AVH and the evolution of the patient's initial diagnosis two years later. DISCUSSION: The originality of our protocol is to explore the potential progression to psychosis from PTSD by cognitive biases. This study supports the hypothesis of connections between PTSD and AVH through sensory, emotional and cognitive biases. It proposes a continuum model from PTSD to psychotic disorder due to impaired perception like AVH. TRIAL REGISTRATION: Clinical trial registration: ClinicalTrials.gov Identifier: NCT03356028.

RÉSUMÉ

PURPOSE OF REVIEW: The assessment of the risk of triggering psychosis upon exposure to grief is a challenge in clinical practice. Adequate diagnosis and early prevention are essential and may be helpful in the evolution of normal grief. We aimed to identify studies exploring grief as a risk factor for developing psychosis. RECENT FINDINGS: A systematic review of 3 databases (PubMed, EMBASE, and Cochrane Library) was conducted. RESULTS: In the first approach 618 studies were identified. After the selection process, 15 studies were included in the review. The association between grief and the risk of developing psychosis occurred at younger ages (before 18 years of age) in a first-degree relative and as a consequence of suicide or accidental death. We found that risk factors such as comorbidity, mental problems, unemployment, economic difficulties, and close ties with the deceased have a negative impact on health causing greater vulnerability to psychosis with a risk of developing complicated grief, with statistically significant results regarding the associations between early parental death and the probability of developing psychosis in adulthood.

RÉSUMÉ

Background and Objectives: Radicalization, a complex and multifaceted phenomenon, has been a subject of increasing concern in recent years, particularly due to its potential connection to acts of mass violence and terrorism. This systematic review examines the intricate link between radicalization and psychotic disorders, utilizing various sources such as observational studies, case reports, and series. It aims to highlight the prevalence of schizophrenia spectrum and other psychotic disorders among radicalized individuals and to define the role of mental health professionals in dealing with this issue, contributing to the development of prevention and treatment strategies. Materials and Methods: The methodology involved an extensive literature search across PubMed, Scopus, and APA PsycINFO up to 1 February 2024, adhering to PRISMA guidelines. The study focused on radicalization and psychotic disorders as defined by DSM-5 criteria, excluding other mental disorders. A population sample of 41 radicalized individuals diagnosed with psychotic disorders was selected, among which schizophrenia was identified as the predominant condition. Results: It was observed that 24% of these individuals passed away soon after committing their crimes, leading the researchers to rely on retrospective data for their diagnoses. The use of diverse assessment tools for psychiatric diagnosis and the lack of a standardized method for diagnosing or assessing involvement in the radicalization process were also noted. Despite limitations like reliance on observational studies and case reports, which result in low evidence quality and varied methodologies, our work provides a valuable contribution to clarifying the relationship between radicalization and psychotic disorders. However, further clinical studies are needed to delve deeper into these aspects. Conclusions: In conclusion, our review points out that individuals with psychotic disorders do not have a higher crime rate than the general population and warns against associating crimes with mental illness due to the stigma it creates. The lack of uniform psychiatric diagnostic tools and radicalization assessment highlights the need for more standardized risk assessment tools and validated scales in psychiatric diagnosis to better understand the relationship between radicalization and psychotic disorders and to develop integrated protocols.

RÉSUMÉ

Eidetic images are a relatively rare phenomenon in the practice of a psychiatrist. They are described in the category of perception disorders as images or memories which, thanks to their plasticity, vividness and detail, are very similar to the currently experienced sensory perceptions. However, it should be remembered that their occurrence is not associated with any mental disorders, and they are also observed in some healthy people. This paper presents a case report of a patient with complaints about "voiced," plastic images - the course of his psychiatric hospitalization and the psychological diagnostics carried out at that time. The authors point out the difficulties in differentiating, first of all, with auditory pseudo-hallucinations and make an attempt at psychopathological classification of the patient's symptoms. The discussion on possible disease mechanisms of this phenomenon is based on reports as well as research on the phenomenon of imagination and eidetic perceptions, and the aim of this study is to draw the attention of diagnosticians to the category of psychological phenomena with an eidetic character, which may allow them to avoid incorrect recognition of them as an element of psychotic disorders of perception.

RÉSUMÉ

Psychotic experiences (PE) are prevalent in general and clinical populations and can increase the risk for mental disorders in young people. The Community Assessment of Psychic Experiences (CAPE) is a widely used measure to assess PE in different populations and settings. However, the current knowledge on their overall reliability is limited. We examined the reliability of the CAPE-42 and later versions, testing the role of age, sex, test scores, and clinical status as moderators. A systematic search was conducted on the Scopus, Web of Science, PubMed, EBSCOhost, ProQuest, and GoogleScholar databases. Internal consistency and temporal stability indices were examined through reliability generalization meta-analysis (RGMA). Moderators were tested through meta-regression analysis. From a pool of 1,015 records, 90 independent samples were extracted from 71 studies. Four versions showed quantitative evidence for inclusion: CAPE-42, CAPE-20, CAPE-P15, and CAPE-P8. Internal consistency indices were good (α/ω≈.725-0.917). Temporal stability was only analyzed for the CAPE-P15, yielding a moderate but not-significant effect (r=0.672). The evidence for temporal stability is scant due to the limited literature, and definitive conclusions cannot be drawn. Further evidence on other potential moderators such as adverse experiences or psychosocial functioning is required.

RÉSUMÉ

BACKGROUND: The link between trauma exposure and psychotic disorders is well-established. Further, specific types of trauma may be associated with specific psychotic symptoms. Network analysis is an approach that can advance our understanding of the associations across trauma types and psychotic symptoms. METHODS: We conducted a network analysis with data from 16,628 adult participants (mean age [standard deviation] = 36.3 years [11.5]; 55.8% males) with psychotic disorders in East Africa recruited between 2018 and 2023. We used the Life Events Checklist and the Mini International Neuropsychiatric Interview to determine whether specific trauma types experienced over the life course and specific psychotic symptoms were connected. We used an Ising model to estimate the network connections and bridge centrality statistics to identify nodes that may influence trauma types and psychotic symptoms. RESULTS: The trauma type "exposure to a war zone" had the highest bridge strength, betweenness, and closeness. The psychotic symptom "odd or unusual beliefs" had the second highest bridge strength. Exposure to a war zone was directly connected to visual hallucinations, odd or unusual beliefs, passivity phenomena, and disorganized speech. Odd or unusual beliefs were directly connected to transportation accidents, physical assault, war, and witnessing sudden accidental death. CONCLUSION: Specific trauma types and psychotic symptoms may interact bidirectionally. Screening for psychotic symptoms in patients with war-related trauma and evaluating lifetime trauma in patients with odd or unusual beliefs in clinical care may be considered points of intervention to limit stimulating additional psychotic symptoms and trauma exposure. This work reaffirms the importance of trauma-informed care for patients with psychotic disorders.

RÉSUMÉ

BACKGROUND: There is a treatment gap for those living with severe mental illnesses in low- and middle-income countries, yet not enough is known about those who are currently accessing clinical services. A better understanding of potentially modifiable factors associated with functioning and quality of life will help inform policies and programming. AIMS: To describe the functioning and quality of life for a psychiatric treatment-engaged population living with psychotic disorders in two urban areas of Tanzania, and to explore their respective correlates. METHODS: This study analyzed cross-sectional data from 66 individuals enrolled in the Kuwezeshana Kupata Uzima (KUPAA) pilot clinical trial who had a diagnosis of schizophrenia or schizoaffective disorder, recent relapse, and who were receiving outpatient treatment. Baseline functioning (WHO Disability Assessment Schedule 2.0) and quality of life (WHO Quality of Life BREF scale) were measured. Univariable and multivariable regression analyses were conducted to determine correlates of functioning and quality of life. RESULTS: Adjusted analyses indicated that higher disability was associated with higher food insecurity, more symptomatology, more self-stigma, less instrumental support, less hope, lower self-efficacy, and/or lower levels of family functioning. Higher quality of life was associated with higher levels of self-efficacy, more hopefulness, more instrumental support, less self-stigma, and better family functioning. CONCLUSIONS: Identification of factors associated with disability and quality of life can help clinicians and policymakers, as well as consumers of mental health services, to better co-design and target psychosocial interventions to optimize their impact in low-resource settings.

RÉSUMÉ

BACKGROUND: Patient participation in treatment decision making is a pillar of recovery-oriented care and is associated with improvements in empowerment and well-being. Although demand for increased involvement in treatment decision-making is high among veterans with serious mental illness, rates of involvement are low. Collaborative decision skills training (CDST) is a recovery-oriented, skills-based intervention designed to support meaningful patient participation in treatment decision making. An open trial among veterans with psychosis supported CDST's feasibility and demonstrated preliminary indications of effectiveness. A randomized control trial (RCT) is needed to test CDST's effectiveness in comparison with an active control and further evaluate implementation feasibility. METHODS: The planned RCT is a hybrid type 1 trial, which will use mixed methods to systematically evaluate the effectiveness and implementation feasibility of CDST among veterans participating in a VA Psychosocial Rehabilitation and Recovery Center (PRRC) in Southern California. The first aim is to assess the effectiveness of CDST in comparison with the active control via the primary outcome, collaborative decision-making behavior during usual care appointments between veterans and their VA mental health clinicians, and secondary outcomes (i.e., treatment engagement, satisfaction, and outcome). The second aim is to characterize the implementation feasibility of CDST within the VA PRRC using the Practical Robust Implementation and Sustainability Model framework, including barriers and facilitators within the PRRC context to support future implementation. DISCUSSION: If CDST is found to be effective and feasible, implementation determinants gathered throughout the study can be used to ensure sustained and successful implementation at this PRRC and other PRRCs and similar settings nationally. TRIAL REGISTRATION: ClinicalTrials.gov NCT04324944. Registered on March 27, 2020. Trial registration data can be found in Appendix 1.

RÉSUMÉ

Importance: Available antipsychotic medications are predominantly used to treat positive symptoms, such as hallucinations and delusions, in patients with first-episode psychosis (FEP). However, treating negative and cognitive symptoms, which are closely related to functional outcomes, remains a challenge. Objective: To explore the cognitive characteristics of patients with negative symptom-dominant (NSD) psychosis. Design, Setting, and Participants: This large-scale cross-sectional study of patients with FEP was led by the Shanghai Mental Health Center in China from 2016 to 2021, with participants recruited from 10 psychiatric tertiary hospitals. A comprehensive cognitive assessment was performed among 788 patients with FEP who were drug-naive. Symptom profiles were determined using the Positive and Negative Symptoms Scale (PANSS), and NSD was defined as a PANSS score for negative symptoms higher than that for positive and general symptoms. Positive symptom-dominant (PSD) and general symptom-dominant (GSD) psychosis were defined similarly. Data were analyzed in 2023. Exposure: Psychotic symptoms were categorized into 3 groups: NSD, PSD, and GSD. Main Outcomes and Measures: Neurocognitive performance, assessed using the Chinese version of the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery. Results: This study included 788 individuals with FEP (median age, 22 [IQR, 17-28] years; 399 men [50.6%]). Patients with NSD exhibited more-pronounced cognitive impairment than did those with PSD or GSD. Specifically, cognitive differences between the NSD and PSD group, as well as between the NSD and GSD group, were most notable in the processing speed and attention domains (Trail Making [F = 4.410; P = .01], Symbol Coding [F = 4.957; P = .007], Verbal Learning [F = 3.198; P = .04], and Continuous Performance [F = 3.057; P = .05]). Patients with PSD and GSD showed no significant cognitive differences. Cognitive impairment was positively associated with the severity of negative symptoms. Most of the cognitive function tests used were able to differentiate patients with NSD from those with PSD and GSD, with significant differences observed across a range of tests, from Brief Visuospatial Memory Test-Revised (χ2 = 3.968; P = .05) to Brief Assessment of Cognition in Schizophrenia symbol coding (χ2 = 9.765; P = .002). Conclusions and Relevance: The findings of this cross-sectional study of patients with FEP suggest the presence of a clinical subtype characterized by a predominance of negative symptoms and cognitive impairment.

RÉSUMÉ

Background: Narrative exposure therapy (NET) is a recommended intervention for people with multiple trauma histories; however, research is lacking into its use with people experiencing psychosis, many of whom report multiple trauma histories.Objective: This study aimed to explore experiences of NET in early intervention in psychosis (EIP) services.Method: Eight clinicians and four experts with lived experience (experts by experience) of psychosis and multiple trauma were interviewed on a single occasion using two versions (clinician and expert by experience) of a semi-structured interview schedule. Data was analysed using thematic analysis.Results: Five overarching themes were generated, relating to fear and avoidance of memories, importance of trust, organizing memories and making new meaning, reconnecting with emotions, and considerations when delivering NET in EIP.Conclusions: Directly addressing the impact of multiple trauma in people experiencing first episode psychosis is frightening and emotive, but helps to address painful memories and organize them into a personal narrative. Increases in distress and anomalous experiences were carefully considered by clinicians, but typically outweighed by the benefits of NET. Challenges were comparable to those described in non-psychosis research. Implications for clinical practice and future research are outlined.


Many people experiencing psychosis report multiple trauma histories. Narrative exposure therapy (NET) is a recommended intervention for people with multiple trauma histories, but research into its use with people experiencing psychosis is limited.This qualitative study found that clinicians and experts by experience in early intervention in psychosis services valued NET for its effect on organizing memories, reducing their emotional impact, and making new meaning around experiences, and that challenges of NET were similar to those described in non-psychosis research.Some participants described experiencing distress and dysregulation during NET, including an increase in anomalous experiences. Although this was typically temporary and outweighed by NET's benefits, careful assessment before and flexibility during the intervention are considered important for building engagement and trust.

RÉSUMÉ

This study examined trajectories of suicide-risk and their relationship to symptoms, recovery, and quality of life over time. Data was obtained from the Recovery after an Initial Schizophrenia Episode Early Treatment Program (RAISE-ETP) study. 404 individuals with first-episode psychosis (FEP) completed measures of suicide-risk, depression, positive symptoms, recovery, and quality of life at baseline, 6mo, 12mo, 18mo, and 24mo. Latent class analysis was used to identify temporal trajectories of suicide-risk. General linear mixed models for repeated measures were used to examine the relationship between the latent trajectories of suicide-risk and clinical variables. Results identified three latent trajectories of suicide-risk (low-risk, worsening, and improving). The low-risk and improving classes experienced improvements in depression, positive symptoms, quality of life, and recovery over time. The worsening class experienced improvements in positive symptoms and quality of life, but no change in depression or recovery. These results suggest that some individuals with FEP are at risk for persistent depression and worsening suicide-risk during treatment despite experiencing improvements in positive symptoms and quality of life. These findings have important clinical implications, as persistent depression and worsening suicide-risk might be masked by the primary focus on positive symptoms and quality of life in most FEP clinics.

RÉSUMÉ

In recent years, there have been significant advances in our understanding of the positive symptoms of schizophrenia, such as hallucinations and delusions. This progress has been significantly aided by the use of associative learning-based approaches in human subjects and preclinical animal models. Here, we first review experimental research focusing on the abnormal processing of absent stimuli using three different conditioning phenomena: conditioned hallucinations, mediated conditioning, and trace conditioning. We then review studies investigating the ability to reduce focal processing of physically present but informationally redundant stimuli using habituation, latent inhibition, and blocking. The results of these different lines of research are then summarized within the framework of Wagner's (1981) standard operating procedures model, an associative learning model with explicit reference to the internal representations of both present and absent stimuli. Within this framework, the central deficit associated with positive symptoms can be described as a failure to suppress the focal processing of both absent stimuli and present but irrelevant stimuli. This can explain the wide range of results obtained in different experimental settings. Finally, we briefly discuss the role of the hippocampus and its interaction with dopaminergic transmission in the emergence of such abnormal stimulus representations and learning. Overall, we hope that the theoretical framework and empirical findings offered by the associative learning approach will continue to facilitate and integrate analyses of schizophrenia conducted at the psychological and behavioral levels on the one hand, and at the neural and molecular levels on the other, by serving as a useful interface between them.

RÉSUMÉ

INTRODUCTION: Childhood trauma and adversities (CTA) and aberrant salience (AS) have a pivotal role in schizophrenia development, but their interplay with psychotic symptoms remains vague. We explored the mediation performed by AS between CTA and psychotic symptomatology in schizophrenia. METHODS: We approached 241 adults suffering from schizophrenia spectrum disorders (SSDs), who have been in the unit for at least 12 consecutive months, excluding the diagnosis of dementia, and recent substance abuse disorder, and cross-sectional evaluated through the Aberrant Salience Inventory (ASI), Childhood Trauma Questionnaire Short-Form (CTQ-SF), and Positive and Negative Symptom Scale (PANSS). We tested a path-diagram where AS mediated the relationship between CTA and psychosis, after verifying each measure one-dimensionality through confirmatory factor analysis. RESULTS: The final sample comprised 222 patients (36.9% female), with a mean age of 42.4 (± 13.3) years and an average antipsychotic dose of 453.6 (± 184.2) mg/day (chlorpromazine equivalents). The mean duration of untreated psychosis was 1.8 (± 2.0) years while the mean onset age was 23.9 (± 8.2) years. Significant paths were found from emotional abuse to ASI total score (ß = 0.39; p < .001) and from ASI total score to PANSS positive (ß = 0.17; p = .019). Finally, a statistically significant indirect association was found from emotional abuse to PANSS positive mediated by ASI total score (ß = 0.06; p = .041; CI 95% [0.01, 0.13]). CONCLUSION: Emotional abuse has an AS-mediated effect on positive psychotic symptomatology. AS evaluation could allow a better characterization of psychosis as well as explain the presence of positive symptoms in adults with SSDs who experienced CTA.

RÉSUMÉ

BACKGROUND: Psychotic-like experiences (PLEs) are common in the general population and have been linked to alcohol misuse and abuse. However, much of this research has been undertaken in Western countries. To address this deficit, the current study examined the association between PLEs and problem drinking in the Japanese general population. METHODS: Data were used from 3717 adults (age 18-89) collected in an online survey in 2023. Information was obtained on PLEs with the PRIME Screen-Revised (PS-R), while problem drinking was assessed with the CAGE questionnaire (where a score of ≥ 2 was used to categorize cases). Logistic regression was used to examine the associations. RESULTS: Problem drinking was prevalent in the study sample (12.5%). In an analysis that was adjusted for sociodemographic factors, self-rated health, smoking status and depressive symptoms, PLEs were associated with significantly higher odds for problem drinking in the total sample (OR: 1.70, 95%CI: 1.13-2.55). In a sex-stratified analysis PLEs were not linked to problem drinking in men (OR: 1.16, 95%CI 0.68-2.00), whereas women with PLEs had over 2.8 times higher odds for problem drinking (OR: 2.83, 95%CI: 1.54-5.21). CONCLUSION: PLEs are associated with problem drinking in the Japanese general population and this association is especially pronounced in women. As problem drinking has been linked to a number of detrimental outcomes, future research should examine the potential effects of problem drinking in individuals with PLEs.

RÉSUMÉ

It is unclear what types of stigma youth at clinical high risk for psychosis (CHR) experience, and the relationship between them and symptomatology. 94 CHR youth, and a control group of 45 youth with no psychosis spectrum symptoms (NP) were rated for perceived devaluation (i.e. negative views from others) and internalized mental health stigma (i.e. the extent to which they would agree with said views) as well as positive and mood symptomatology. CHR youth reported stigma more frequently than the NP group (χ2(1) = 53.55, p < .001) and at higher levels (perceived devaluation: t (137) = 8.54, p < .001; internalized stigma: t (137) = 7.48, p < .001). Surprisingly, in the CHR group, positive symptoms held no significant relationship to stigma measures. However, ratings of perceived devaluation stigma were associated with depressive symptomatology (ß = 0.27, t = 2.68, p = .0087) and depression scores were conversely associated with perceived devaluation stigma (ß = 0.30, t = 2.05, p = .043). These findings speak to the relationship between depressive symptomatology and perceived devaluation stigma in CHR youth. Perceived devaluation stigma showed greater clinical significance and could have different mechanisms than internalized stigma in CHR youth. It is also noteworthy that while positive symptoms play a central role in defining the CHR syndrome, they seem less relevant to the experience of stigma than mood symptoms. These findings highlight the importance of interventions aimed at ameliorating youth's exposure to negative views about mental health as those managing depressive symptomatology.

RÉSUMÉ

BACKGROUND: Despite high rates of suicide among people with psychosis, relatively little is known about the mechanisms underlying the transition from suicidal ideation to behavior in this population. The Interpersonal Psychological Theory of Suicide (IPTS) proposes that fearlessness about death (FAD) may play a role in this relationship. The present study tested whether constructs of the IPTS [thwarted belongingness (TB), perceived burdensomeness (PB), and FAD] were associated with the severity of suicidal ideation in a sample of adults with histories of psychosis. METHOD: 261 adults with histories of psychosis completed measures of IPTS constructs, current severity of suicidal ideation, and history of suicidal attempts. We examined differences between those with past suicide attempts and those without and conducted regression analyses to evaluate the associations among TB, PB, FAD and severity of current suicidal ideation. RESULTS: Contrary to expectations, a history of suicidal behavior was not uniquely associated with FAD. Regression analyses revealed TB × PB and FAD × PB interactions emerged as significant correlates of the severity of suicidal ideation, with the relationship between PB and suicidal ideation more pronounced at higher levels of FAD and TB. Interestingly, positive symptoms of psychosis were positively associated with PB. IMPLICATIONS: This study provides support for broadening the investigation of FAD as a contributor to suicidal ideation in individuals with psychotic symptoms. Future research investigating the role of other contributors that may influence capability for suicide (e.g., impulsivity) may add additional understanding of suicide in this population.

RÉSUMÉ

Bodily self-disturbances including anomalous embodiment of emotions are observed in psychosis-spectrum conditions. Psychosis is also associated with trauma exposure but the relationship between altered bodily experiences and trauma has not been extensively investigated in individuals at risk for psychosis (HR). We implemented a mapping task to localize felt sensations associated with trauma. Results show that trauma experiences were always localized in the body. HR reported increased rates of traumatic experiences than low-risk group (LR). HR reported sensations associated with trauma across widespread body areas. Further research is needed to elucidate how trauma might lead to psychotic-like experiences via bodily self-disturbances.
