Clin Psychol Rev 2025; 117:102564. [PMID: 40058297 DOI: 10.1016/j.cpr.2025.102564] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 01/04/2025] [Accepted: 02/25/2025] [Indexed: 04/06/2025]
Abstract
Developmental trauma (DT), defined as abuse or neglect before age 18, is linked with elevated risk and poorer outcomes in psychosis. This systematic review aimed to elucidate the relationship between DT and dissociation in psychosis and discern the potential mediating role of dissociation in the link between DT and psychotic manifestations. Our study protocol was pre-registered with PROSPERO (CRD42022330026). We adopted broad criteria, including a variety of methodologies exploring dissociation post-DT in individuals exhibiting psychosis or psychotic features. Risk of bias was assessed for all included studies. Our review incorporated 40 studies, totalling 6941 participants. A significant moderate association was observed between DT and dissociation (r = 0.33 (95 %CI: 0.28-0.38)), underscored by dose-response effects. Sexual and emotional abuse demonstrated the most robust associations with dissociation. Individuals with psychosis and DT reported elevated dissociation relative to their non-traumatized counterparts. Dissociation mediated the link between DT and positive psychotic symptoms, notably hallucinations, across clinical and general populations. Five studies pinpointed dissociation's mediating role in tying DT to paranoia and delusional ideation. The review delves into clinical considerations, emphasizing screening for psychotic and dissociative symptoms in DT survivors, and outlining dissociation management strategies. Future research, employing longitudinal, qualitative, and experimental approaches, remains paramount.

Abstract
A mental illness can lead to a distortion in a person's capacity to engage with the world and other people in a variety of ways. This is particularly relevant to schizophrenia and autism spectrum disorder (ASD), which are not only historically linked, but also overlap clinically in several respects. From a phenomenological point of view, the differences or similarities between both disorders have not yet been sufficiently investigated. Schizophrenic autism can be characterized as a disorder of three interconnected dimensions, namely the self, intersubjectivity and the self's relationship with the life-world. The present work therefore investigates differences in these three dimensions between the two disorders. One key difference is that the self-world relationship in schizophrenia can be described as unstable or fragmented, whereas in ASD it is considered stable. Finally, possible differences in the experience of delusions are discussed as a change in the self's relationship with the world.

Abstract
Increasing evidence suggests that, as in other medical fields, there are pronounced pediatric mental health disparities with greater burden among marginalized racial and ethnic youth. The reasons for these disparities are not fully understood. One way to explain pediatric mental health disparities is through the lens of environmental stress as a driver of mental health burden, given that marginalized populations are exposed to more structural and individual stress. Although traditionally stress has been linked to specific psychiatric disorders that fall under the umbrella of "stress-related disorders" such as acute/post-traumatic stress disorder or adjustment disorder, broader conceptual frameworks include depression (including suicidality) and anxiety as stress related. More recently, there has been growing recognition of the contribution of early life stressful exposures (ie, childhood adversity) to psychosis spectrum disorders. As such, recognition of the role of stress exposure in psychotic presentations and the fact that exposure to adverse social determinants of health and stressful environments is more common among youth of color can serve as a potential mechanism to explain pediatric disparities in psychosis risk.

Abstract
BACKGROUND Complex post-traumatic stress disorder (cPTSD) is a newly recognized condition characterized by core PTSD symptoms and disturbances in self-organization (DSO) that has been associated with psychotic-like experiences (PLEs). This study employs two psychopathology network approaches to identify which post-traumatic symptoms are related to PLEs in a sample of late adolescents. We propose that cPTSD symptoms play a crucial role in explaining the co-occurrence of trauma and PLEs. METHODS A sample of 1010 late adolescents provided measures of post-traumatic symptomatology and PLEs. We estimated the Gaussian graphical network structure of PTSD/cPTSD symptoms and PLEs and assessed their bridge centrality indices. Bayesian network analysis was then used to estimate a directed acyclic graph (DAG). Gender was set as a moderator in both Gaussian and Bayesian models. RESULTS Results show that affect dysregulation, a cPTSD domain, presented the highest bridge connection with the PLE cluster. Bayesian network analysis identified a pathway going from cPTSD items of worthlessness and relational dysregulation, to PLE items of paranoia and social anxiety. Additionally, we found relevant gender differences in network connectivity, with females showing higher connectivity compared to males. CONCLUSIONS Our findings highlight the central role of affect dysregulation and negative self-concept in linking cPTSD to PLE symptoms, with specific differences according to gender. These insights underscore the need for targeted, gender-sensitive approaches in the prevention and treatment of PLEs among adolescents, emphasizing early intervention and tailored treatment strategies.

Abstract
BACKGROUND Symptoms of complex post-traumatic stress disorder (cPTSD) may play a role in the maintenance of psychotic symptoms. Network analyses have shown interrelationships between post-traumatic sequelae and psychosis, but the temporal dynamics of these relationships in people with psychosis and a history of trauma remain unclear. We aimed to explore, using network analysis, the temporal order of relationships between symptoms of cPTSD (i.e. core PTSD and disturbances of self-organization [DSOs]) and psychosis in the flow of daily life. METHODS Participants with psychosis and comorbid PTSD (N = 153) completed an experience-sampling study involving multiple daily assessments of psychosis (paranoia, voices, and visions), core PTSD (trauma-related intrusions, avoidance, hyperarousal), and DSOs (emotional dysregulation, interpersonal difficulties, negative self-concept) over six consecutive days. Multilevel vector autoregressive modeling was used to estimate three complementary networks representing different timescales. RESULTS Our between-subjects network suggested that, on average over the testing period, most cPTSD symptoms related to at least one positive psychotic symptom. Many average relationships persist in the contemporaneous network, indicating symptoms of cPTSD and psychosis co-occur, especially paranoia with hyperarousal and negative self-concept. The temporal network suggested that paranoia reciprocally predicted, and was predicted by, hyperarousal, negative self-concept, and emotional dysregulation from moment to moment. cPTSD did not directly relate to voices in the temporal network. CONCLUSIONS cPTSD and positive psychosis symptoms mutually maintain each other in trauma-exposed people with psychosis via the maintenance of current threat, consistent with cognitive models of PTSD. Current threat, therefore, represents a valuable treatment target in phased-based trauma-focused psychosis interventions.

Abstract
Dating violence during adolescence is a global public health issue due to its widespread occurrence and negative health consequences. Unfortunately, research addressing this topic in Latin American countries remains limited. Seeking to bridge this gap, the present study estimated the prevalence of both dating violence victimization and perpetration among high schoolers considering sociodemographic factors, exposure to other forms of violence, and school-related characteristics. A total of 539 students participated in the study selected by means of probabilistic sampling from private and public schools in Rio de Janeiro, Brazil. Dating violence was identified using the Conflict in Adolescent Dating Relationships Inventory. Victimization prevalence ranged from 16.7% (sexual) to 94.6% (emotional), whereas perpetration prevalence varied between 9.9% (sexual) and 94.6% (emotional). Boys were more physically victimized (37.2% vs. 24.5%) and perpetrated more sexual abuse (13.7% vs. 6.9%) than girls. Adolescents reporting child abuse, living in violent areas, and those who consumed alcoholic beverages more frequently had greater dating violence prevalence overall. However, some differences between male and female vulnerability characteristics merit debate. These heterogeneous profiles of victimization/perpetration between boys and girls indicate the need for specific dating violence prevention interventions.

Neuroimaging stratification reveals the striatal vulnerability to stress as a risk for schizophrenia. Transl Psychiatry 2025; 15:18. [PMID: 39843416 PMCID: PMC11754660 DOI: 10.1038/s41398-025-03237-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2024] [Revised: 12/16/2024] [Accepted: 01/14/2025] [Indexed: 01/24/2025] Open
Abstract
The striatum, a core brain structure relevant for schizophrenia, exhibits heterogeneous volumetric changes in this illness. Due to this heterogeneity, its role in the risk of developing schizophrenia following exposure to environmental stress remains poorly understood. Using the putamen (a subnucleus of the striatum) as an indicator for convergent genetic risk of schizophrenia, 63 unaffected first-degree relatives of patients (22.08 ± 4.80 years) with schizophrenia (UFR-SZ) were stratified into two groups. Compared with healthy controls (HC; n = 59), voxel-based and brain-wide volumetric changes and their associations with stressful life events (SLE) were tested. These stratified associations were validated using two large population-based cohorts (the ABCD study; n = 1680, 11.92 ± 0.62 years; and UK Biobank, n = 20547, 55.38 ± 7.43 years). Transcriptomic analysis of brain tissues was used to identify the biological processes associated with the brain mediation effects on the SLE-psychosis relationship. The stratified UFR-SZ subgroup with smaller right putamen had a smaller volume in the left caudate when compared to HC; this caudate volume was associated with both a higher level of SLE and more psychotic symptoms. This caudate-SLE association was replicated in two independent large-scale cohorts, when individuals were stratified by both a higher polygenic burden for schizophrenia and smaller right putamen. In UFR-SZ, the caudate cluster mediated the relationship between SLE and more psychotic symptoms. This mediation was associated with the genes enriched in both glutamatergic synapses and response to oxidative stress. The stratified association between the striatum and stress highlights the differential vulnerability to stress, contributing to the complexity of the gene-by-environment etiology of schizophrenia.

Abstract
Bullying among South African adolescents is a critical public health issue. This study explores the relationship between childhood adversity, peer influence, and personality traits in predicting bullying perpetration. Data from 769 high school learners were analysed using Structural Equation Modelling. Findings indicate that childhood adversity predicts bullying perpetration, mediated by peer influence and moderated by personality traits like conscientiousness, extraversion, and emotional stability. These results support Social Learning Theory, emphasising observed behaviours and peer dynamics in bullying. Practical implications include targeted interventions addressing childhood adversity and fostering positive peer interactions and personality development.

Abstract
BACKGROUND Both childhood adversity (CA) and first-episode psychosis (FEP) have been linked to alterations in cortical thickness (CT). The interactive effects between different types of CAs and FEP on CT remain understudied. METHODS One-hundred sixteen individuals with FEP (mean age = 23.8 ± 6.9 years, 34% females, 80.2% non-affective FEP) and 98 healthy controls (HCs) (mean age = 24.4 ± 6.2 years, 43% females) reported the presence/absence of CA <17 years using an adapted version of the Childhood Experience of Care and Abuse (CECA.Q) and the Retrospective Bullying Questionnaire (RBQ) and underwent magnetic resonance imaging (MRI) scans. Correlation analyses were used to assess associations between brain maps of CA and FEP effects. General linear models (GLMs) were performed to assess the interaction effects of CA and FEP on CT. RESULTS Eighty-three individuals with FEP and 83 HCs reported exposure to at least one CA. CT alterations in FEP were similar to those found in participants exposed to separation from parents, bullying, parental discord, household poverty, and sexual abuse (r = 0.50 to 0.25). Exposure to neglect (β = -0.24, 95% CI [-0.37 to -0.12], p = 0.016) and overall maltreatment (β = -0.13, 95% CI [-0.20 to -0.06], p = 0.043) were associated with cortical thinning in the right medial orbitofrontal region. CONCLUSIONS Cortical alterations in individuals with FEP are similar to those observed in the context of socio-environmental adversity. Neglect and maltreatment may contribute to CT reductions in FEP. Our findings provide new insights into the specific neurobiological effects of CA in early psychosis.

Abstract
Trauma-related beliefs are theorized to contribute to the development and maintenance of psychosis symptoms. However, the evidence for this proposal has yet to be systematically reviewed. This article is the first to synthesize and meta-analyze studies examining associations between trauma-related beliefs and psychosis symptoms, including hallucinations, delusions, paranoia, and negative symptoms. A systematic database search of Medline, PsychINFO, Embase, Web of Science, CINHAL, and Cochrane identified a total of 15 articles that met the inclusion criteria for systematic review and 11 articles which met the inclusion criteria for meta-analysis. Separate random-effects meta-analyses were conducted for each psychosis symptom. Meta-analytic findings demonstrated a small to moderate association between trauma-related beliefs and hallucination severity (k = 7, r = 0.25, 95% CI 0.10-0.39), a moderate to large association with delusion severity (k = 8, r = 0.43, 95% CI 0.31-0.54), and large association with paranoia severity (k = 4, r = 0.58, 95% CI 0.49-0.66). Narrative synthesis findings indicate that evidence for an association between negative symptoms and trauma-related beliefs was inconclusive. The meta-analytic findings provide support for an association between trauma-related beliefs and positive psychosis symptoms. This provides evidence suggesting trauma therapies for psychosis that target these beliefs may improve distressing psychosis. However, further research adopting longitudinal designs and controlling for confounders is required to better establish causality, including mediation analysis of therapy trials.

Abstract
BACKGROUND AND HYPOTHESIS Transition to psychosis rates within ultra-high risk (UHR) services have been declining. It may be possible to 'enrich' UHR cohorts based on the environmental characteristics seen more commonly in first-episode psychosis cohorts. This study aimed to determine whether transition rates varied according to the accumulated exposure to environmental risk factors at the individual (migrant status, asylum seeker/refugee status, indigenous population, cannabis/methamphetamine use), family (family history or parental separation), and neighborhood (population density, social deprivation, and fragmentation) level. METHODS The study included UHR people aged 15-24 who attended the PACE clinic from 2012 to 2016. Cox proportional hazards models (frequentist and Bayesian) were used to assess the association between individual and accumulated factors and transition to psychosis. UHR status and transition was determined using the CAARMS. Benjamini-Hochberg was used to correct for multiple comparisons in frequentist analyses. RESULTS Of the 461 young people included, 55.5% were female and median follow-up was 307 days (IQR: 188-557) and 17.6% (n = 81) transitioned to a psychotic disorder. The proportion who transitioned increased incrementally according to the number of individual-level risk factors present (HR = 1.51, 95% CIs 1.19-1.93, p < 0.001, pcorr = 0.01). The number of family- and neighborhood-level exposures did not increase transition risk (p > 0.05). Cannabis use was the only specific risk factor significantly associated with transition (HR = 1.89, 95% CIs 1.22-2.93, pcorr = 0.03, BF = 6.74). CONCLUSIONS There is a dose-response relationship between exposure to individual-level psychosis-related environmental risk factors and transition risk in UHR patients. If replicated, this could be incorporated into a novel approach to identifying the highest-risk individuals within clinical services.

The effect of polygenic risk score and childhood adversity on transdiagnostic symptom dimensions at first-episode psychosis: evidence for an affective pathway to psychosis. Transl Psychiatry 2024; 14:454.

Abstract
Childhood adversity is associated with various clinical dimensions in psychosis; however, how genetic vulnerability shapes the adversity-associated psychopathological signature is yet to be studied. We studied data of 583 First Episode Psychosis (FEP) cases from the EU-GEI FEP case-control study, including Polygenic risk scores for major depressive disorder (MDD-PRS), bipolar disorder (BD-PRS) and schizophrenia (SZ-PRS); childhood adversity measured with the total score of the Childhood Trauma Questionnaire (CTQ); and positive, negative, depressive and manic psychopathological domains from a factor model of transdiagnostic dimensions. Genes and environment interactions were explored as a departure from a multiplicative effect of PRSs and total CTQ on each dimension. Analyses were adjusted for age, sex, 10 PCA, site of recruitment and for medication. A childhood adversity and PRS multiplicative interaction was observed between A) the CTQ and MDD-PRS on the predominance of positive (β = 0.42, 95% CI = [0.155, 0.682], p = 0.004); and depressive (β = 0.33, 95% CI = [0.071, 0.591], p = 0.013) dimensions; B) between the CTQ and BD-PRS on the positive dimension (β = 0.45, 95% CI = [0.106, 0.798], p = 0.010), and C) with the CTQ and SZ-PRS on the positive dimension (β = -0.34, 95% CI = [-0.660, -0.015], p = 0.040). Bonferroni corrected p-value of significance was set at 0.0125. In conclusion, despite being underpowered, this study suggests that genetic liability for MDD and BD may have a moderating effect on the sensibility of childhood adversity on depressive and positive psychotic dimensions. This supports the hypothesis of an affective pathway to psychosis in those exposed to childhood adversity.

Abstract
INTRODUCTION Child maltreatment (CM) is associated with adverse cognitive, behavioural, physical and social outcomes that often continue until adulthood. Systematic reviews on mediators and moderators of this relationship mostly investigate childhood adversities in general or only with regard to an adult population, single outcomes or single forms of maltreatment. The purpose of this review is to synthesise the evidence of variables that mediate and/or moderate the relationship between CM and diverse outcomes. METHOD A systematic search will be performed in Scopus, PsychInfo, Medline and Web of Science until January 2022. Eligibility criteria include children under 18 years who have been maltreated and experienced adverse outcomes until the age of 21, moderators and/or mediators that influence the relationship between maltreatment and adverse outcomes must belong to the individual level and be amenable to change. After independent screening of studies by two reviewers, data extraction and study quality of included studies will be done using adapted checklists of similar reviews, the Strengthening the Reporting of Observational Studies in Epidemiology report, the COnsensus-based Standards for the selection of health Measurement INstruments checklist and Downs and Black Checklist. The results will be presented in narrative form and, if adequate, meta-analysis. ETHICS AND DISSEMINATION Ethics approval will not be required. The results of this systematic review will be submitted for publication in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42022297982.

Abstract
Childhood disadvantage is associated with increased adult psychological distress, but the role of behavioral risk factors in the pathway remains unclear. We examined whether behavioral risk factors mediate the effects of childhood disadvantage on adult psychological distress. We used the Helsinki Health Study data of employees of the City of Helsinki, Finland, aged 19-39 (mean age 32.0) years at baseline (2017). We included women (n = 2397) and men (n = 586) who responded to both baseline and follow-up (2022) surveys. At baseline, eight types of childhood disadvantage were asked retrospectively, and six adult behavioral risk factors were included. Psychological distress was measured by the DASS-21 at follow-up. We conducted mediation analyses using generalized structural equation modeling. Among women, we found indirect path effects of childhood disadvantage on adult psychological distress through behavioral risk factors (symptoms of depression: β = 0.68, 95% CI 0.20-1.17; anxiety: β = 0.54, 95% CI 0.13-0.95; and stress: β = 0.69, 95% CI 0.20-1.09). Among men, childhood disadvantage contributed only directly to adult depressive (β = 0.71, 95% CI 0.16-1.26) and stress (β = 0.61, 95% CI 0.10-1.13) symptoms. Our findings suggest that behavioral risk factors can mediate some of the adverse effects of childhood disadvantage on adult psychological distress among women.

Abstract
BACKGROUND Post-traumatic stress disorder (PTSD) has been shown to predict psychotic symptomology. However, few studies have examined the relative contribution of PTSD compared to broader post-traumatic sequelae in maintaining psychosis. Complex PTSD (cPTSD), operationalized using ICD-11 criteria, includes core PTSD (intrusions, avoidance, hyperarousal) as well as additional "disturbances of self-organisation" (DSO; emotional dysregulation, interpersonal difficulties, negative self-concept) symptoms, more likely to be associated with complex trauma histories. It was hypothesized that DSOs would be associated with positive psychotic symptoms (paranoia, voices, and visions) in daily life, over and above core PTSD symptoms. METHODS This study (N = 153) employed a baseline subsample of the Study of Trauma And Recovery (STAR), a clinical sample of participants with comorbid post-traumatic stress and psychosis symptoms. Core PTSD, DSO and psychosis symptoms were assessed up to 10 times per day at quasi-random intervals over six consecutive days using Experience Sampling Methodology. RESULTS DSOs within the preceding 90 min predicted paranoia, voices, and visions at subsequent moments. These relationships persisted when controlling for core PTSD symptoms within this timeframe, which were themselves significant. The associations between DSOs and paranoia but not voices or visions, were significantly stronger than those between psychosis and core PTSD symptoms. CONCLUSIONS Consistent with an affective pathway to psychosis, the findings suggest that DSOs may be more important than core PTSD symptoms in maintaining psychotic experiences in daily life among people with comorbid psychosis and cPTSD, and indicate the potential importance of addressing broad post-traumatic sequelae in trauma-focused psychosis interventions.

Abstract
BACKGROUND During the last decades, an abundance of studies has investigated childhood adversity in relation to psychosis. This systematic review critically examines the methodologies employed to investigate childhood adversity in psychosis over the past decade, including operational definitions, measurement tools and characteristics, and psychometric properties of instruments used in these studies. STUDY DESIGN This systematic review followed the PRISMA guidelines (registration number CRD42022307096), and the search used the following electronic databases: PsychINFO, SCOPUS, Web of Science, African Index Medicus (AIM), LILACS, CINAHL, EMBASE, and MEDLINE. The search included variations and combinations of the terms targeting childhood adversity and psychosis. STUDY RESULTS Out of 585 identified studies published between 2010 and 2023, 341 employed a validated instrument to investigate childhood adversity. Our findings show "childhood trauma" being the most frequently examined construct, followed by "child maltreatment" or "child abuse." The short version of the Childhood Trauma Questionnaire was the dominant instrument. Physical abuse, emotional abuse, and sexual abuse were most frequently investigated, and indeed the field appears generally to focus on child abuse and neglect over other adversities. Significant psychometric heterogeneity was observed in the selection and summarization of instrument items, with only 59% of studies documenting original psychometric validation and 22% reporting reliability in their datasets. CONCLUSION This review highlights substantial methodological heterogeneity in the field, pointing out biases in the research on childhood adversity and psychosis. These findings underline the need for standardized definitions and high-quality measurement tools to enhance the validity of future research in this area.

Abstract
AIMS Various concepts are used to study the impact of stress on childhood development. These concepts are often used inconsistently or interchangeably. Our main objectives were to determine how selected stress concepts (chronic stress, toxic stress, allostatic load, early life stress, childhood adversity, childhood trauma and adverse childhood experiences; ACEs) are defined, operationalized and described, and to provide a theoretical context to aid the choice for a preferred concept in public health research. METHODS For this descriptive review, we systematically searched for literature published before 4 August 2021, on PubMed, Embase and PsycInfo. Two independent reviewers included studies. Exclusion criteria were: no systematic review, not peer reviewed, not published in English, selected stress concepts were no predetermined variable or a substantial topic in the discussion, full text was unobtainable or study described non-human or non-childhood populations. Data extraction forms were used. Descriptives were gathered, publication fields were identified through Journal Citation Reports categories, and verbatim descriptions were ordered in text and Venn diagrams. RESULTS Of 264 screened studies, 124 were included. ACEs, childhood adversity and childhood trauma were used most. ACEs were the main concept used most frequently (47.6%). A total of 11 of 14 public and environmental health journals used ACEs. All concepts refer to prolonged, repeated, interpersonal stress from 0 to 18 years, that can alter physiological systems. Four concepts were stressor oriented, two concepts focused on stress response and effect and one on the state of challenged homeostasis. CONCLUSIONS ACEs seem most fitting for public health setting, due to their operationalizability, large set of core experiences and widespread use.

Abstract
Adverse childhood experiences (ACEs) are a well-known risk factor of schizophrenia. Moreover, individuals with schizophrenia are likely to use maladaptive stress coping strategies. Although it has been reported that a history of ACEs might be associated with a pro-inflammatory phenotype in patients with schizophrenia, the interacting effect of coping styles on this association has not been tested so far. In the present study, we aimed to investigate the levels of immune-inflammatory markers in patients with schizophrenia and healthy controls (HCs), taking into consideration a history of ACEs and coping strategies. Participants included 119 patients with schizophrenia and 120 HCs. Serum levels of 26 immune-inflammatory markers were determined. A history of any categories of ACEs was significantly more frequent in patients with schizophrenia. Moreover, patients with schizophrenia were significantly more likely to use emotion-focused coping and less likely to use active coping strategies compared to HCs. The levels of interleukin(IL)-6, RANTES, and tumor necrosis factor-α (TNF-α), appeared to be elevated in patients with schizophrenia after adjustment for potential confounding factors in all tested models. Participants reporting a history of any ACEs had significantly higher levels of TNF-α and IL-6. No significant main and interactive effects of active strategies as the predominant coping on immune-inflammatory markers with altered levels in patients with schizophrenia were found. Findings from the present study indicate that ACEs are associated with elevated TNF-α and IL-6 levels regardless of schizophrenia diagnosis and predominant coping styles.

Abstract
BACKGROUND AND HYPOTHESIS Childhood adversity is often described as a potential cause of incident psychotic experiences, but the underlying mechanisms are not well understood. We aimed to examine the mediating role of cognitive and psychopathological factors in the relation between childhood adversity and incident psychotic experiences in early adulthood. STUDY DESIGN We analyzed data from the Avon Longitudinal Study of Parents and Children, a large population-based cohort study. Childhood adversity was measured prospectively from birth to age 11 years, mediators (anxiety, depression, external locus of control [LoC], negative symptoms) were assessed at approximately 16 years of age, and incident psychotic experiences were assessed at ages 18 and 24 years. Mediation was examined via the counterfactual g-computation formula. STUDY RESULTS In total, 7% of participants had incident suspected or definite psychotic experiences in early adulthood. Childhood adversity was related to more incident psychotic experiences (ORadjusted = 1.34, 95% CI = 1.21; 1.49), and this association was partially mediated via all mediators examined (proportion mediated: 19.9%). In separate analyses for each mediator, anxiety, depression, external LoC, and negative symptoms were all found to mediate the link between adversity and incident psychotic experiences. Accounting for potential confounders did not modify our results. CONCLUSIONS Our study shows that cognitive biases as well as mood symptomatology may be on the causal pathway between early-life adversity and the development of psychotic experiences. Future studies should determine which mediating factors are most easily modifiable and most likely to reduce the risk of developing psychotic experiences.

Abstract
BACKGROUND Class and social disadvantage have long been identified as significant factors in the etiology and epidemiology of psychosis. Few studies have explicitly examined the impact of intersecting social disadvantage on long-term employment and financial independence. METHODS We applied latent class analysis (LCA) to 20-year longitudinal data from participants with affective and non-affective psychosis (n = 256) within the Chicago Longitudinal Research. LCA groups were modeled using multiple indicators of pre-morbid disadvantage (parental social class, educational attainment, race, gender, and work and social functioning prior to psychosis onset). The comparative longitudinal work and financial functioning of LCA groups were then examined. RESULTS We identified three distinct latent classes: one comprised entirely of White participants, with the highest parental class and highest levels of educational attainment; a second predominantly working-class group, with equal numbers of Black and White participants; and a third with the lowest parental social class, lowest levels of education and a mix of Black and White participants. The latter, our highest social disadvantage group experienced significantly poorer employment and financial outcomes at all time-points, controlling for diagnosis, symptoms, and hospitalizations prior to baseline. Contrary to our hypotheses, on most measures, the two less disadvantaged groups did not significantly differ from each other. CONCLUSIONS Our analyses add to a growing literature on the impact of multiple forms of social disadvantage on long-term functional trajectories, underscoring the importance of proactive attention to sociostructural disadvantage early in treatment, and the development and evaluation of interventions designed to mitigate ongoing social stratification.

Abstract
BACKGROUND Childhood maltreatment (CM) is a strong risk factor for psychiatric disorders but serves in its current definitions as an umbrella for various fundamentally different childhood experiences. As first step toward a more refined analysis of the impact of CM, our objective is to revisit the relation of abuse and neglect, major subtypes of CM, with symptoms across disorders. METHODS Three longitudinal studies of major depressive disorder (MDD, N = 1240), bipolar disorder (BD, N = 1339), and schizophrenia (SCZ, N = 577), each including controls (N = 881), were analyzed. Multivariate regression models were used to examine the relation between exposure to abuse, neglect, or their combination to the odds for MDD, BD, SCZ, and symptoms across disorders. Bidirectional Mendelian randomization (MR) was used to probe causality, using genetic instruments of abuse and neglect derived from UK Biobank data (N = 143 473). RESULTS Abuse was the stronger risk factor for SCZ (OR 3.51, 95% CI 2.17-5.67) and neglect for BD (OR 2.69, 95% CI 2.09-3.46). Combined CM was related to increased risk exceeding additive effects of abuse and neglect for MDD (RERI = 1.4) and BD (RERI = 1.1). Across disorders, abuse was associated with hallucinations (OR 2.16, 95% CI 1.55-3.01) and suicide attempts (OR 2.16, 95% CI 1.55-3.01) whereas neglect was associated with agitation (OR 1.24, 95% CI 1.02-1.51) and reduced need for sleep (OR 1.64, 95% CI 1.08-2.48). MR analyses were consistent with a bidirectional causal effect of abuse with SCZ (IVWforward = 0.13, 95% CI 0.01-0.24). CONCLUSIONS Childhood abuse and neglect are associated with different risks to psychiatric symptoms and disorders. Unraveling the origin of these differences may advance understanding of disease etiology and ultimately facilitate development of improved personalized treatment strategies.

Abstract
As recently as the late 20th century, Schizophrenia, a category of mental illness with widely varying phenotypic symptoms, was believed by psychobiologists to be a genetically based disorder in which the environment played a limited etiological role. Yet a growing body of evidence indicates a strong correlation between schizophrenia and environmental factors. This theoretical paper explores the relationship between highly elevated rates of schizophrenia in some low-income minority communities worldwide and trauma-related dissociative symptoms that often mimic schizophrenia. Elevated rates of schizophrenia in racially and ethnically isolated, inner-city Black populations are well documented. This paper contains evidence proposing that this amplification in the rate of schizophrenia is mediated by childhood trauma, disorganized attachment, and social defeat. Further, evidence demonstrating how these three variables combine in early childhood to incubate dissociative disorders will also be conveyed. The misdiagnosis of dissociative disorders as schizophrenia is theorized to partially mediate the increased rate of schizophrenia in communities that experience high levels of racial/ethnic discrimination. It is argued that this misdiagnosis is often attributable to cultural misunderstanding and/or a lack of knowledge about dissociative disorders.

Abstract
Adverse childhood experiences (ACEs) are well-established risk factors for psychotic symptoms. This study replicated the relationship between ACEs and positive symptoms of psychosis in the Asian context and explored the moderating effect of dissociation. We analyzed data from 1439 high school students in China who completed validated measures of ACEs, positive symptoms of psychosis, and dissociative symptoms. The positive relationship between ACEs and psychotic symptoms was confirmed in our sample (r =0.244, p <0.001). Among different ACEs, childhood emotional neglect (β =0.139, p <0.001) and emotional abuse (β =0.125, p <0.001) had the strongest relationship with psychotic symptoms. Dissociative symptoms were also found to be a statistically significant moderator. We provide cross-cultural evidence for the relationship between ACEs and psychotic symptoms. Dissociative symptoms may exacerbate such effects. These results highlight the importance of child protection to prevent psychotic symptoms. Individuals with higher levels of dissociation may be at higher risk of developing psychotic symptoms when exposed to adversities. A trauma-informed approach to addressing psychotic symptoms in the community is recommended.

Abstract
Existing literature provides extended evidence of the close relationship between stress dysregulation, environmental insults, and psychosis onset. Early stress can sensitize genetically vulnerable individuals to future stress, modifying their risk for developing psychotic phenomena. Neurobiological substrate of the aberrant stress response to hypothalamic-pituitary-adrenal axis dysregulation, disrupted inflammation processes, oxidative stress increase, gut dysbiosis, and altered brain signaling, provides mechanistic links between environmental risk factors and the development of psychotic symptoms. Early-life and later-life exposures may act directly, accumulatively, and repeatedly during critical neurodevelopmental time windows. Environmental hazards, such as pre- and perinatal complications, traumatic experiences, psychosocial stressors, and cannabis use might negatively intervene with brain developmental trajectories and disturb the balance of important stress systems, which act together with recent life events to push the individual over the threshold for the manifestation of psychosis. The current review presents the dynamic and complex relationship between stress, environment, and psychosis onset, attempting to provide an insight into potentially modifiable factors, enhancing resilience and possibly influencing individual psychosis liability.

Association of Childhood Adversity With Frailty and the Mediating Role of Unhealthy Lifestyle: A Lifespan Analysis. Am J Geriatr Psychiatry 2024; 32:71-82. [PMID: 37770350 PMCID: PMC11078585 DOI: 10.1016/j.jagp.2023.08.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 08/10/2023] [Accepted: 08/23/2023] [Indexed: 09/30/2023]
Abstract
OBJECTIVES Childhood adversity and lifestyle have been associated with frailty in later life, but not much is known about factors that may explain these associations. Therefore, this study aims to investigate the association of childhood adversity with frailty, and the mediating role of unhealthy lifestyle in the association. METHODS This lifespan analysis included 152,914 adults aged 40-69 years old from the UK Biobank. We measured childhood adversity with five items: physical neglect, emotional neglect, sexual abuse, physical abuse, and emotional abuse through online mental health survey. Frailty was measured by the frailty index; an unhealthy lifestyle score (range: 0-5) was calculated based on unhealthy body mass index, smoking, alcohol consumption, physical inactivity, and unhealthy diet at the baseline survey. Multiple logistic regression and mediation analysis were performed. RESULTS A total of 10,078 participants (6.6%) were defined as having frailty. Participants with any childhood adversity had higher odds of frailty. For example, in the fully adjusted model, with a one-point increase in cumulative score of childhood adversity, the odds of frailty increased by 38% (odds ratio: 1.38; 95% Confidence Interval: 1.36, 1.40). Unhealthy lifestyle partially mediated the associations of childhood adversity with frailty (mediation proportion: 4.4%-7.0%). The mediation proportions were largest for physical (8.2%) and sexual (8.1%) abuse. CONCLUSIONS Childhood adversity was positively associated with frailty, and unhealthy lifestyle partially mediated the association. This newly identified pathway highlights the potential of lifestyle intervention strategies among those who experienced childhood adversity (in particular, physical, and sexual abuse) to promote healthy aging.

Psychiatry Res 2024; 331:115614. [PMID: 38039651 DOI: 10.1016/j.psychres.2023.115614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 11/14/2023] [Accepted: 11/17/2023] [Indexed: 12/03/2023]
Abstract
Patients with first-episode psychoses (FEP) exhibit heterogeneity in clinical manifestations and outcomes. This study investigated the long-term trajectories of six key psychopathological dimensions (reality-distortion, negative, disorganization, catatonia, mania and depression) in patients diagnosed with FEP. A total of 243 patients were followed up for 20 years and the trajectories of the dimensions were analysed using growth mixture modelling. These dimensions showed varied course patterns, ranging from two to five trajectories. Additionally, the study examined the predictive value of different factors in differentiating between the long-term trajectories. The exposome risk score showed that familial load, distal and intermediate risk factors, acute psychosocial stressors and acute onset were significant predictors for differentiating between long-term psychopathological trajectories. In contrast, polygenic risk score, duration of untreated psychosis and duration of untreated illness demonstrated little or no predictive value. The findings highlight the importance of conducting a multidimensional assessment not only at FEP but also during follow-up to customize the effectiveness of interventions. Furthermore, the results emphasize the relevance of assessing premorbid predictors from the onset of illness. This may enable the identification of FEP patients at high-risk of poor long-term outcomes who would benefit from targeted prevention programs on specific psychopathological dimensions.

How first-episode psychosis patients' subjective beliefs about their childhood trauma's causal effect provide support for potential schizophrenia subtypes. Schizophr Res 2023; 262:175-183.

Abstract
BACKGROUND Childhood and adolescent trauma is a risk factor for developing psychosis-spectrum disorders. The current study aimed to assess how childhood trauma might predict psychosis symptomatology, and how patients' beliefs of whether trauma is the cause of psychosis might affect this association. METHODS Ninety-six first-episode psychosis patients were assessed for childhood traumatic experiences with the Brief Betrayal Trauma Survey, and for psychosis symptoms with the Positive and Negative Syndrome Scale. RESULTS Non-interpersonal trauma predicted higher positive symptoms, whereas more trauma domains experienced predicted lower negative symptoms. Almost half of the participants believed trauma to be related to psychosis, were 12 times more likely to reexperience trauma through psychosis, and had higher excitative and emotional symptoms. Non-interpersonal trauma also predicted higher positive symptoms in this group. Those who did not believe trauma to be the cause of psychosis had higher negative symptoms, and a negative dose-response was found for negative and disorganised symptoms, in which more trauma domains experienced predicted lower scores. CONCLUSIONS Results imply two traumagenic pathways to psychosis, one characterised by positive, excitative, and emotional symptoms, and one negative subtype, characterised by negative and disorganised symptoms. Clinical implications for how findings might contribute to better treatments are discussed.

Abstract
Psychosocial stressors have been suggested to precipitate psychotic episodes in patients with pre-existing psychosis and otherwise healthy subjects. However, such a risk has never been formally investigated in individuals with autism spectrum disorder (ASD). Sixty-nine autistic adolescents hospitalized for psychotic/manic symptoms (PSY) and other mental health issues (NPSY) over a 9-year period were compared with reference to their previous exposure to psychosocial stressors. ASD diagnoses satisfied the International Classification of Diseases (ICD)-10 criteria. Psychotic/manic symptom assessment followed the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS). Psychosocial stressor exposure was collected separately at each admission. Preliminarily, univariate between-group comparisons were conducted. Then, a binomial model was adopted to investigate associations with previous exposure to psychosocial stressors. Results were reported with a change in AIC (ΔAIC). PSY patients presented with higher previous exposure to adverse life events (30.43% vs. 6.52%, OR = 6.079 [1.209, 40.926], p = 0.013) and school/work difficulties (30.43% vs. 8.70%, OR = 4.478 [0.984, 23.846], p = 0.034) than NPSY ones. Admissions for psychotic/manic symptoms occurred more likely in the context of family disturbances (OR = 2.275 [1.045, 5.045], p = 0.030) and adverse life events (OR = 3.489 [1.194, 11.161], p = 0.014). The fitted binomial model was found to be significant compared to the random effects model (ΔAIC = -1.962; χ2 10 = 21.96, p = 0.015), with the risk of presenting psychotic/manic symptoms being increased by family disturbances (z = +4.118) and school/work difficulties (z = +2.455). The results suggest a potential psychosis-inducing effect of psychosocial stressors in ASD, which has clinical and policy implications.

Abstract
Background: Migration is a multi-stage social process linked to traumatic event exposure and a notably increased risk of psychosis. Although these conditions affect refugee and non-refugee immigrants, prior trauma research has focused mainly on the refugee population.Objective: To compare and describe the rate and the clinical characterization of PTSD and traumatic events between non-refugee immigrants and native-born individuals with psychotic disorder.Methods: 99 immigrants and 99 native-born individuals (n = 198) with at least one psychotic episode according to DSM-5 criteria were compared on the rate of PTSD diagnosis and traumatic events, using standardized and validated trauma scales.Results: In the non-refugee immigrant group, 31% met diagnostic criteria for PTSD compared to only 7.1% in the native-born group. Total scores in childhood trauma and last year stressful events were 1.5 and 2 times higher in non-refugee immigrants, respectively. Likewise, cumulative lifetime trauma was three times higher in non-refugee immigrants. Finally, non-refugee immigrants reported more violent and life-threatening traumatic events than native-born individuals.Conclusions: These results are relevant since they highlight that non-refugee immigrants with psychotic disorders are highly trauma-exposed, meaning a routine trauma assessment and a trauma-focused intervention for this population should be included in individualized treatment plans.

Abstract
This study investigated if the association between childhood maltreatment and cognition among psychosis patients and community controls was partially accounted for by genetic liability for psychosis. Patients with first-episode psychosis (N = 755) and unaffected controls (N = 1219) from the EU-GEI study were assessed for childhood maltreatment, intelligence quotient (IQ), family history of psychosis (FH), and polygenic risk score for schizophrenia (SZ-PRS). Controlling for FH and SZ-PRS did not attenuate the association between childhood maltreatment and IQ in cases or controls. Findings suggest that these expressions of genetic liability cannot account for the lower levels of cognition found among adults maltreated in childhood.

Abstract
Background Increasing research efforts have focused on understanding why some individuals develop severe psychopathology after exposure to adverse childhood experiences (ACEs). Sleep disturbances (insomnia, nightmares, and sleep disorders) are prevalent sequelae of ACEs and associated with psychopathology; however, there is no meta-analytic evidence on whether sleep disturbance functions as a transdiagnostic mediator in the relationship between ACEs and psychopathology (internalizing/externalizing disorders and psychosis) in children and adolescents. Methods Systematic searches in three databases (PubMed; PsycINFO; Web of Science) identified 98 articles (N = 402,718; age range 1-17 years) and the present study used a novel two-stage meta-analytic structural equation model to investigate whether ACEs predict psychopathology through sleep disturbance. Subgroup analyses determined potential biases due to study design (cross-sectional vs. longitudinal) and geographical differences (Western vs. non-Western countries). Sensitivity analyses evaluated the influence of early childhood (<5 years old) and overlapping symptoms (i.e., nightmares and trauma symptoms) on model stability. Results The pooled correlations among ACEs, sleep disturbance, and psychopathology were significant; the effect sizes ranged from moderate to high (r = 0.21 to r = 0.29). The indirect effect from ACEs via sleep disturbance to psychopathology was significant (β = 0.05, 95% CI [0.04, 0.06]). The direct effect of ACEs on psychopathology was significant (β = 0.18, 95% CI 0.13-0.24). Subgroup analyses revealed larger effects for cross-sectional studies than longitudinal studies (Δ χ2 (3) = 9.71, p = 0.021). Sensitivity analyses revealed stable and consistent results. Conclusions The present meta-analytic results indicate that sleep disturbance is a transdiagnostic mediator in the relationship between ACEs and psychopathology among children and adolescents. Further research is required to determine the synergistic effects between sleep disturbance and other risk mechanisms, and elucidate the complex pathways that lead to disorder in the aftermath of childhood adversities.

Abstract
BACKGROUND A large body of evidence has established a tight relation between traumatic experiences (TEs) and psychotic-like experiences (PLEs). Nevertheless, more comprehensive models involving multiple interactions of serial or parallel mediations and moderations still need to be elucidated. Among the many potential mediators or moderators, insecure attachment and resilience play a key role in the association of stress with PLEs. Hence, we aim to explore the complex pathways that lead from different types of TEs to PLEs, involving attachment and resilience modeled as mediators or moderators. METHODS One thousand ten high school students completed the International Trauma Exposure Measure (ITEM), the 11-item Resilience Scale for Adults (RSA-11), the 16-item Prodromal Questionnaire (iPQ-16), and the Relationship Questionnaire (RQ). A path analysis was conducted to assess mediation and moderation. RESULTS The final model showed that the impact of childhood TEs on PLEs was mediated by a pathway through anxious-insecure attachment styles (i.e., fearful and preoccupied, respectively, 8.75 % and 8.53 % of the total effect) and personal resilience resources. Conversely, the avoidant-insecure attachment was associated with lower interpersonal resilience (b = 0.14 [0.08, 0.20]), which in turn moderated the impact of recent TEs on PLEs (interaction term b = 0.34 [0.21, 0.47]). CONCLUSIONS Our model examines a complex model that includes factors buffering the effect of traumatic experiences on PLEs. Our results highlight the importance of insecure-anxious attachment to personal resilience resources and of insecure-avoidant attachment to interpersonal resilience as potential targets for clinical practice.

Abstract
Social risk factors are long-term or repeated environmental exposures in childhood and youth that change the brain and may, via epigenetic effects, change gene expression. They thus have the power to initiate or aggravate mental disorders. Because these effects can be mediated via hormonal or immune/inflammatory pathways that differ between men and women, their influence is often sex-specific. The goal of this narrative review is to explore the literature on social risk factors as they affect women with schizophrenia. We searched the PubMed and Scopus databases from 2000 to May 2023 using terms referring to the various social determinants of health in conjunction with "women" and with "schizophrenia". A total of 57 studies fulfilled the inclusion criteria. In the domains of childhood and adult abuse or trauma, victimization, stigma, housing, and socioeconomics, women with schizophrenia showed greater probability than their male peers of suffering negative consequences. Interventions targeting appropriate housing, income support, social and parenting support, protection from abuse, violence, and mothering-directed stigma have, to different degrees, yielded success in reducing stress levels and alleviating the many burdens of schizophrenia in women.

Associations between plasma inflammatory markers and psychotic disorder, depressive disorder and generalised anxiety disorder in early adulthood: A nested case-control study. Brain Behav Immun 2023; 111:90-100. [PMID: 37004760 DOI: 10.1016/j.bbi.2023.03.025] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 03/10/2023] [Accepted: 03/28/2023] [Indexed: 04/04/2023] Open
Abstract
BACKGROUND Low-grade inflammation may occur in association with several mental disorders of early adulthood, though associations with markers of chronic inflammation such as soluble urokinase plasminogen activator receptor (suPAR) are less well-established. We aimed to examine associations between acute and chronic inflammatory markers and mental disorders, as well as psychiatric co-morbidity, in young adults aged 24 years in the Avon Longitudinal Study of Parents and Children. METHODS Included were 781 participants (of 4019 who attended at age 24 years) who completed psychiatric assessments and provided plasma samples. Of these, 377 met criteria for psychotic disorder, depressive disorder or generalised anxiety disorder and 404 did not. Plasma concentrations of IFN-γ, IL-6, IL-8, IL-10, TNF-α, CRP, sVCAM1, sICAM1, suPAR and alpha-2-macroglobulin were measured using immunoassays. Logistic regression compared standardised inflammatory marker levels in cases and controls. Negative binomial regression evaluated associations between inflammatory markers and co-morbidity (number of mental disorders). Models were adjusted for sex, body mass index, cigarette smoking, cannabis use and employment status, then additionally for childhood trauma. RESULTS For psychotic disorder, there was evidence for associations with IL-6 (odds ratio[OR] 1.68, 95 %CI 1.20-2.34) and suPAR (OR 1.74, 95 %CI 1.17-2.58). There was weaker evidence for an association between suPAR and depressive disorder (OR 1.31, 95 %CI 1.05-1.62). There was little evidence for associations between inflammatory markers and generalised anxiety disorder. There was weak evidence for an association between suPAR and co-morbidity (β 0.10, 95 %CI 0.01-0.19). There was little evidence for additional confounding by childhood trauma. CONCLUSIONS There was evidence that 24-year-olds with psychotic disorder had raised plasma IL-6 and suPAR concentrations compared to controls. These findings have implications regarding the role of inflammation in mental disorders in early adulthood.

Abstract
BackgroundIncreased hair cortisol concentrations (HCC) have been found in clinical samples of schizophrenia, first episode psychosis and clinical risk for psychosis, but evidence of such is scarce in schizotypy. High HCC are supposed to reflect elevated chronic stress. However, HCC were not directly associated with adversity measures and stress-related phenotypes in previous research. This study tested whether HCC moderated the association between a comprehensive range of psychosocial stressors with several stress-related phenotypes in a sample of nonclinical young adults. It was expected that stressors, either distal (i.e., early-life) or recent, would be associated with subclinical features, particularly for those with elevated HCC, reflecting the effects of a potential biological sensitization to stress.MethodsThe sample comprised 132 nonclinical young adults belonging to the Barcelona Longitudinal Investigation of Schizotypy Study (BLISS). Participants completed a questionnaire of childhood adversity and two complementary measures of recent life events, tapping threatening vs. more general life events. Both the frequency and subjective impact (positive vs. negative) of general life events were also assessed. Psychotic (i.e., schizotypy, suspiciousness) and non-psychotic (i.e., depression, anxiety) subclinical features as well as appraisals of perceived stress were examined. Hierarchical linear regressions and simple slope analyses were computed.ResultsHCC moderated the effects of both early and recent stress on suspiciousness as well as the effects of recent life events on perceived stress, such that those with higher HCC presented increased suspiciousness and perceived stress at higher levels of stress exposure. Positive, but not negative, recent life events were associated with decreased perceived stress and depression, and these associations were moderated by low HCC, indicating a buffering effect for those with a non-impaired HPA axis.ConclusionIn line with the neural diathesis-stress model, results highlight the role of the interplay between the HPA axis and exposure to stressful experiences in exacerbating psychosis features and extend evidence to the nonclinical expression of the psychosis continuum. In addition, findings support the protective effect of positive experiences in decreasing stress appraisals and affective disturbances, which is consistent with emerging research about the relevance of positive factors in reducing the likelihood of psychopathological outcomes.

Abstract
Childhood adversity (CA) and resilience may impact on paranoia, but mechanisms underlying these associations are largely unknown. In this study, we investigated two potential candidates: irrational beliefs and affective disturbance. Moreover, we investigated the potential moderating role of COVID-19 perceived stress in these associations. A community sample (N = 419, m age = 27.32 years, SD = 8.98; 88.10% females) completed self-report measures. Results indicated that paranoia was significantly associated with CA and resilience (p < .05), and both irrational beliefs and affective disturbance (i.e., depressive and anxiety symptoms) mediated the associations between CA and paranoia. Moreover, depressive and anxiety symptoms partially explained the mediating role of irrational beliefs. These predictive models explained up to 23.52% of variance in paranoia (F(3,415) = 42.536, p < .001). Findings on resilience and paranoia replicated these results, and COVID-19 perceived stress moderated the association between resilience and ideas of persecution. Overall, these findings underscore the importance of irrational beliefs, depressive and anxiety symptoms in high CA or low resilience individuals experiencing paranoia.

Abstract
Childhood maltreatment has been suggested to have an adverse impact on neurodevelopment, including microstructural brain abnormalities. Existing neuroimaging findings remain inconsistent and heterogeneous. We aim to explore the most prominent and robust cortical thickness (CTh) and gray matter volume (GMV) alterations associated with childhood maltreatment. A systematic search on relevant studies was conducted through September 2022. The whole-brain coordinate-based meta-analysis (CBMA) on CTh and GMV studies were conducted using the seed-based d mapping (SDM) software. Meta-regression analysis was subsequently applied to investigate potential associations between clinical variables and structural changes. A total of 45 studies were eligible for inclusion, including 11 datasets on CTh and 39 datasets on GMV, consisting of 2550 participants exposed to childhood maltreatment and 3739 unexposed comparison subjects. Individuals with childhood maltreatment exhibited overlapped deficits in the median cingulate/paracingulate gyri simultaneously revealed by both CTh and GM studies. Regional cortical thinning in the right anterior cingulate/paracingulate gyri and the left middle frontal gyrus, as well as GMV reductions in the left supplementary motor area (SMA) was also identified. No greater regions were found for either CTh or GMV. In addition, several neural morphology changes were associated with the average age of the maltreated individuals. The median cingulate/paracingulate gyri morphology might serve as the most robust neuroimaging feature of childhood maltreatment. The effects of early-life trauma on the human brain predominantly involved in cognitive functions, socio-affective functioning and stress regulation. This current meta-analysis enhanced the understanding of neuropathological changes induced by childhood maltreatment.

Abstract
BACKGROUND Previous Scandinavian studies have shown increased levels of psychiatric morbidity in young refugees and international adoptees with an origin outside Europe. This study investigated their risk of non-affective psychotic disorders (NAPD) and whether this risk is influenced by early childhood adversity, operationalised as age at adoption/residency, and/or gender. METHODS Register study in Swedish national cohorts born 1972-1990 including 21 615 non-European international adoptees, 42 732 non-European refugees that settled in Sweden at age 0-14 years and 1 610 233 Swedish born. The study population was followed from age 18 to year 2016 for hospitalisations with a discharge diagnosis of NAPD. Hazard ratios (HRs) were calculated in gender stratified Cox regression models, adjusted for household income at age 17. RESULTS The adjusted risks of NAPD were 2.33 [95% confidence interval (CI) 2.07-2.63] for the international adoptees and 1.92 (1.76-2.09) for the former child refugees, relative to the Swedish-born population. For the international adoptees there was a stepwise gradient for NAPD by age of adoption from adjusted HR 1.66 (1.29-2.03) when adopted during the first year of life to adjusted HR 4.56 (3.22-6.46) when adopted at ages 5-14 years, with a similar risk pattern in women and men. Age at residency did not influence the risk of NAPD in the refugees, but their male to female risk ratio was higher than in Swedish-born and the adoptees. CONCLUSION The risk pattern in the international adoptees gives support to a link between early childhood adversity and NAPD. Male gender increased the risk of NAPD more among the refugees.

Abstract
Background Childhood adversity and lifestyle have been associated with frailty in later life, but not much is known about factors that may explain these associations. An unhealthy lifestyle may play an important role in the pathway from childhood adversity to frailty. Therefore, this study aims to investigate the association of childhood adversity with frailty, and the mediating role of unhealthy lifestyle in the association. Methods This lifespan analysis included 152914 adults aged 40-69 years old from the UK Biobank. We measured childhood adversity with five items: physical neglect, emotional neglect, sexual abuse, physical abuse, and emotional abuse through online mental health survey. Frailty was measured by the frailty index; an unhealthy lifestyle score (range: 0-5) was calculated based on unhealthy body mass index, smoking, drinking, physical inactivity, and unhealthy diet at the baseline survey. Multiple logistic regression and mediation analysis were performed. Results A total of 10078 participants (6.6%) were defined as having frailty. Participants with any childhood adversity had higher odds of frailty. For example, in the fully adjusted model, with a one-point increase in cumulative score of childhood adversity, the odds of frailty increased by 41% (Odds Ratio: 1.41; 95% Confidence Interval: 1.39, 1.44). Unhealthy lifestyle partially mediated the associations of childhood adversity with frailty (mediation proportion: 4.4%-7.0%). The mediation proportions were largest for physical (8.2%) and sexual (8.1%) abuse. Conclusions Among this large sample, childhood adversity was positively associated with frailty, and unhealthy lifestyle partially mediated the association. This newly identified pathway highlights the potential of lifestyle intervention strategies among those who experienced childhood adversity (in particular, physical and sexual abuse) to promote healthy aging.

Abstract
Psychotic-like experiences (PLEs), including persecutory ideation, bizarre experiences, and perceptual abnormalities, are considered risk factors for psychotic disorders and mental distress in the general population. The cognitive-affective mechanisms associated with PLEs remain under-investigated. We aimed to longitudinally assess the reciprocal associations between perseverative cognition (PC), an emerging transdiagnostic factor of psychopathology, and PLEs facets in young adults. Participants (n = 160) from the general population completed measures of PC and PLEs at baseline and at 2-month follow-up. A two-wave, three-variable, cross-lagged panel model was implemented controlling for well-established correlates of PC and PLEs such as depression, anxiety, and symptoms of sleep disturbance. Both PLEs and PC exhibited substantive rank-order stability (β ranged from 0.359 to 0.657, ps < 0.001). Cross-lagged effects revealed that baseline PC was associated with bizarre experiences at 2-month follow-up (β = 0.317; p < 0.01). This effect overcame the well-established cut-off for practical significance. In contrast, no baseline PLEs were associated with PC at follow-up. Findings suggest the presence of a monodirectional, rather than bidirectional, association between PC and bizarre experiences in young adulthood. Results should be interpreted in light of the relatively small, non-clinical, and convenient sample.

Abstract
Background and Hypothesis The role of early adversity and trauma is increasingly recognized in psychosis but treatments for trauma and its consequences are lacking. Psychological treatments need to understand the prevalence of these experiences, the relationship with specific symptoms and identify potentially tractable processes that may be targeted in therapy. It was hypothesized that greater adversity, and specifically abuse rather than neglect, would be associated with positive symptoms and specifically hallucinations. In addition, negative beliefs would mediate the relationship with positive symptoms. Study Design 292 Patients with treatment resistant psychosis completed measures of early adversity as well as current symptoms of psychosis. Study Results Early adversity in the form of abuse and neglect were common in one-third of the sample. Adversity was associated with higher levels of psychotic symptoms generally, and more so with positive rather than negative symptoms. Abuse rather than neglect was associated with positive but not with negative symptoms. Abuse rather than neglect was associated with hallucinations but not delusions. Abuse and neglect were related to negative beliefs about the self and negative beliefs about others. Mediation demonstrated a general relationship with adversity, negative-self, and other views and overall psychotic symptoms but not in relation to the specific experience of abuse and hallucinations. Females were more likely to be abused, but not neglected, than males. Conclusions Whilst most relationships were modest, they supported previous work indicating that adversity contributes to people with psychosis experiencing distressing symptoms especially hallucinations. Treatments need to address and target adversity.

Abstract
Background Childhood trauma is a risk factor for psychosis. It is proposed this is due to traumatic events giving rise to psychological mechanisms that are implicated in the development and maintenance of symptoms. Investigation of the psychological mechanisms accounting for relationships between trauma and psychosis will be assisted by focusing on specific trauma profiles, hallucination modalities, and delusion subtypes. Study Design In 171 adults with schizophrenia-spectrum diagnoses and high-conviction delusions, associations between childhood trauma classes, and hallucination and delusion factors, were tested using structural equation models (SEMs). Anxiety, depression, and negative schema were examined as potential mediators of trauma class-psychosis symptom factor links. Study Results Significant associations were found between the emotional abuse/neglect and poly-victimization classes with persecutory delusions and delusions of influence, that were all mediated through anxiety (β = 1.24-0.23, P = < .05). There was an association between the physical abuse class and grandiose/religious delusions that was not explained by the mediators (β = 1.86, P = < .05). Trauma class was not significantly associated with any hallucination modality (β = 0.004-1.46, P = > .05). Conclusions In a sample of people with strongly held delusions, this study demonstrates that childhood victimization is associated with delusions of influence and grandiose beliefs, as well as with persecutory delusions in psychosis. Consistent with previous findings, the potent, mediating role of anxiety supports affective pathway theories and the utility of targeting threat-related processes when treating trauma effects in psychosis.

Abstract
BACKGROUND AND HYPOTHESIS Previous studies have shown a robust relationship between childhood adversity and subsequent psychotic symptoms. However, the role of familial risk factors underlying this relationship remains largely unclear. Here, we tested whether offspring childhood adversity and postnatal maternal psychopathology mediated the relationship between maternal childhood adversity and offspring psychotic experiences. STUDY DESIGN N = 3068 mother-offspring dyads were included. Maternal history of childhood adversity was retrospectively assessed using the Childhood Trauma Questionnaire during pregnancy. Maternal psychopathology was assessed during and after pregnancy. Twenty-four offspring childhood adversities were assessed by maternal interview when the child was 10 years old. Offspring psychotic experiences were examined using self-report at 14 years. Structural equation mediation models were conducted to explore whether maternal postnatal psychopathology and offspring childhood adversities sequentially mediated the relationship between maternal childhood adversity and offspring psychotic experiences. Analyses were adjusted for sociodemographic confounders. STUDY RESULTS Maternal history of childhood adversity was associated with offspring childhood adversities (β = 0.12, 95% CI: 0.09 to 0.16). Offspring childhood adversity mediated the association of maternal childhood adversity with offspring hallucinations (βindirect effect = 0.008, 95% CI: 0.002 to 0.014, proportion mediated = 16.3%) and delusions (βindirect effect = 0.006, 95% CI: 0.000 to 0.012, proportion mediated = 13.1%). CONCLUSIONS Intergenerational transmission of childhood adversity can be considered of relevance in the etiology of psychosis vulnerability and can potentially serve as a modifiable risk factor.

Abstract
Recent evidence shows that genetic and environmental risk factors for psychotic disorders are associated with higher levels of schizotypy (or psychosis proneness) in the general population. However, little is known about how these risk factors interact. We specifically examined whether genetic loading for schizophrenia moderates the association between childhood trauma severity and schizotypy. Schizotypy was measured using the Schizotypal Personality Questionnaire (SPQ), and childhood trauma severity was measured with the Childhood Trauma Questionnaire (CTQ) among a total of 168 participants (comprising 51 healthy individuals, 56 diagnosed with schizophrenia, and 61 with bipolar disorder). Polygenic risk scores (PRS) for schizophrenia were calculated for all participants and examined as a potential moderator of associations between total scores on the CTQ and schizotypy total scores and dimensions (i.e., cognitive-perceptual, interpersonal, disorganised). Multiple linear regression models revealed associations between childhood trauma and all dimensions of schizotypy, but no associations between PRS and schizotypy. A significant interaction between PRS and childhood trauma was evident for the interpersonal and disorganised dimensions of schizotypy, as well as the total score, reflecting positive associations between childhood trauma severity and these two schizotypal dimensions, only for individuals with low or average PRS for schizophrenia. This suggests that trauma may be able to increase risk for psychosis independently of any genetic vulnerability. The present findings are consistent with the idea of several risk pathways for the development of psychotic disorders.

Abstract
OBJECTIVES Transdiagnostic risk factors-disrupted processes common to psychopathology-link adverse childhood experiences to severe mental disorders (i.e. major depressive disorder, bipolar disorder, and schizophrenia spectrum disorders); however, transdiagnostic protective factors are understudied. The present study investigated the association between a positive mental health framework of protective intra- and interpersonal resources and severe mental disorders in individuals with adverse childhood experiences. We hypothesized that (1) individuals with adverse childhood experiences will experience more severe mental disorders and poorer intra- and interpersonal resources than those without adverse childhood experiences; (2) intrapersonal (e.g. general coping) and interpersonal resources (e.g. emotional support) will interact to predict severe mental disorders. METHODS A total of 1929 adults participated in this population-based study. Participants were assessed for adverse childhood experiences, severe mental disorders, and intra- and interpersonal resources (general coping, general affect, emotional support, interpersonal skills, spirituality, and personal growth and autonomy) via structured interviews and self-reports. RESULTS As hypothesized, individuals with adverse childhood experiences (62.6%) experienced more severe mental disorders and poorer intra- and interpersonal resources than those without adverse childhood experiences. Among those with adverse childhood experiences, emotional support interacted with general coping and general affect to predict severe mental disorders; general coping and general affect were negatively associated with severe mental disorders at high (+1 SD) and low (-1 SD) emotional support, respectively. CONCLUSIONS The present study identified interactions between specific intrapersonal (i.e. general coping and general affect) and interpersonal resources (i.e. emotional support); knowing among whom and when to intervene are essential for optimal treatment of adverse childhood experiences and severe mental disorders.

Abstract
INTRODUCTION Adverse childhood experiences (ACEs) increase the risk of psychotic experiences (PE), but little is known about heterogeneities of this association in different developmental stages, dimensions, or whether they are affected by substance use disorder (SUD). This study examines the association between different types of ACEs at various developmental stages and lifetime PE in patients with SUD in Chile. METHODS We included 399 consenting adults in outpatient or residential SUD treatment programs. Sociodemographic data and information about PE and ACEs were obtained by trained clinical psychologists. RESULTS Patients reporting PE experienced more ACEs compared to patients without PE (4.2 versus 3.4). They also experienced more complex adversities (41.8% versus 25.1%), had more psychiatric comorbidities (85% versus 70.4%), and reported using more substances (mean 4.5 versus 3.9). Adjusted association between ACEs and PE showed the highest OR for arrests (1.88), sexual abuse (1.81), alcohol abuse by parents (1.48), school exclusion (1.39), foster or residential care (18.3). CONCLUSION Early exposure to ACEs is a risk factor for later PE among patients with SUD. Type of ACE and the period when they occurred is important, suggesting the existence of critical periods where the individual is more susceptible to adverse environmental stimuli.

Abstract
While genetic factors play a critical role in the risk for schizophrenia and other psychotic disorders, increasing evidence points to the role of childhood adversity as one of several environmental factors that can significantly impact the development, manifestations and outcome of these disorders. This paper reviews the epidemiological evidence linking childhood adversity and psychotic disorders and explores various theoretical models that seek to explain the connection. We discuss neurobiological parallels between the impact of childhood trauma and psychosis on the brain and then explore the impact of childhood adversity on different domains of clinical presentation. Finally, implications for prevention and treatment are considered, both on individual and structural levels.

Abstract
BACKGROUND AND HYPOTHESIS Schizophrenia has been robustly associated with multiple genetic and environmental risk factors. Childhood adversity is one of the most widely replicated environmental risk factors for schizophrenia, but it is unclear if schizophrenia genetic risk alleles contribute to this association. STUDY DESIGN In this systematic review and meta-analysis, we assessed the evidence for gene-environment correlation (genes influence likelihood of environmental exposure) between schizophrenia polygenic risk score (PRS) and reported childhood adversity. We also assessed the evidence for a gene-environment interaction (genes influence sensitivity to environmental exposure) in relation to the outcome of schizophrenia and/or psychosis. This study was registered on PROSPERO (CRD42020182812). Following PRISMA guidelines, a search for relevant literature was conducted using Cochrane, MEDLINE, PsycINFO, Web of Science, and Scopus databases until February 2022. All studies that examined the association between schizophrenia PRS and childhood adversity were included. STUDY RESULTS Seventeen of 650 identified studies met the inclusion criteria and were assessed against the Newcastle-Ottawa Scale for quality. The meta-analysis found evidence for gene-environment correlation between schizophrenia PRS and childhood adversity (r = .02; 95% CI = 0.01, 0.03; P = .001), but the effect was small and therefore likely to explain only a small proportion of the association between childhood adversity and psychosis. The 4 studies that investigated a gene-environment interaction between schizophrenia PRS and childhood adversity in increasing risk of psychosis reported inconsistent results. CONCLUSIONS These findings suggest that a gene-environment correlation could explain a small proportion of the relationship between reported childhood adversity and psychosis.

Abstract
BACKGROUND Epidemiological studies show that adverse childhood experiences (ACE) are associated with positive psychotic symptoms in Western populations; however, there is a lack of population-based data in multi-ethnic, Asian societies. OBJECTIVE We investigated the associations between ACE (type and dosage) and positive psychotic symptoms in a nationally representative study in Singapore. PARTICIPANTS AND SETTING A total of 4441 adult Singapore residents were recruited via door-to-door surveys; they were assessed for ACE and positive psychotic symptoms (i.e., hallucinations, delusions, thought insertion, thought control, and telepathic powers) on structured interviews. METHODS Lifetime experiences of positive psychotic symptoms were regressed on (1) the experience of any ACE; (2) cumulative ACE; and (3) the experience of either no ACE, interpersonal victimization only, dysfunctional home environments only, neglect only or multiple exposures to ACE in weighted and adjusted regression models. RESULTS 5.2 % of the sample experienced positive psychotic symptoms during their lifetime. Individuals exposed to dysfunctional home environments (OR = 2.84, 95 % CI 1.26 to 6.37) and multiple adverse childhood experiences (OR = 3.31, 95 % CI 2.18 to 5.01) were at an elevated risk of experiencing positive psychotic symptoms. The exposure to three or more ACE was associated with a near five-fold higher risk of experiencing positive psychotic symptoms (OR = 4.51, 95 % CI 2.89 to 7.05). CONCLUSIONS Individuals exposed to dysfunctional home environments or multiple adverse childhood experiences are at an elevated risk of experiencing positive psychotic symptoms. Given the intrafamilial nature of these childhood adversities, dual-generation approaches and family-centered interventions are key.
