Abstract
BACKGROUND Developmental trauma increases psychosis risk and is associated with poor prognosis. It has been proposed that psychosis in survivors of developmental trauma gives rise to a distinct 'traumatogenic' phenotype. AIMS Given the implications for personalised treatment, we sought to explore the traumatogenic psychosis phenotype hypothesis in a systematic review and meta-analysis of studies comparing psychotic presentations between adults with and without developmental trauma histories. METHOD We registered the systematic review on PROSPERO (CRD42019131245) and systematically searched EMBASE, Medline and PsycINFO. The outcomes of interests were quantitative and qualitative comparisons in psychotic symptom expression (positive, negative, cognitive) and other domains of psychopathology, including affect regulation, sleep, depression and anxiety, between adults with and without experience of developmental trauma. RESULTS Of 34 studies included (N = 13 150), 11 were meta-analysed (n = 2842). A significant relationship was found between developmental trauma and increased symptom severity for positive (Hedge's g = 0.27; 95% CI 0.10-0.44; P = 0.002), but not negative symptoms (Hedge's g = 0.13; 95% CI -0.04 to 0.30; P = 0.14). Developmental trauma was associated with greater neurocognitive, specifically executive, deficits, as well as poorer affect, dissociation and social cognition. Furthermore, psychotic symptom content thematically related to traumatic memories in survivors of developmental trauma. CONCLUSIONS Our findings that developmental trauma is associated with more severe positive and affective symptoms, and qualitative differences in symptom expression, support the notion that there may be a traumatogenic psychosis phenotype. However, underdiagnosis of post-traumatic stress disorder may also explain some of these findings. More research is needed to explore this further.

Childhood trauma and treatment resistance in first-episode psychosis: Investigating the role of premorbid adjustment and duration of untreated psychosis. Schizophr Res 2024; 270:441-450. [PMID: 38991420 DOI: 10.1016/j.schres.2024.07.001] [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: 07/04/2023] [Revised: 07/02/2024] [Accepted: 07/03/2024] [Indexed: 07/13/2024]
Abstract
BACKGROUND Early identification of treatment non-response in first-episode psychosis (FEP) is essential to outcome. Despite indications that exposure to childhood trauma (CT) can have adverse effects on illness severity, its impact on treatment non-response and the interplay with other pre-treatment characteristics is sparsely investigated. We use a lack of clinical recovery as an early indicator of treatment resistance to investigate the relationship between CT and treatment resistance status at one-year follow-up and the potential mediation of this effect by other pre-treatment characteristics. METHODS This prospective one-year follow-up study involved 141 participants recruited in their first year of treatment for a schizophrenia-spectrum disorder. We investigated clinical status, childhood trauma (CT), premorbid adjustment (PA), and duration of untreated psychosis (DUP) at baseline and clinical status at one-year follow-up. Ordinal regression analyses were conducted to investigate how PA and DUP affected the relationship between CT and one-year outcome in FEP. RESULTS 45 % of the FEP sample reported moderate to severe CT, with significantly higher levels of CT in the early treatment resistant group compared to participants with full or partial early recovery. Ordinal regression analysis showed that CT was a significant predictor of being in a more severe outcome group (OR = 4.59). There was a partial mediation effect of PA and a full mediation effect of DUP on the effect of CT on outcome group membership. DISCUSSION Our findings indicate that reducing treatment delays may mitigate the adverse effects of CT on clinical outcomes and support the inclusion of broad trauma assessment in FEP services.

Abstract
BACKGROUND The relationship between childhood trauma (CT) and psychotic symptoms in patients with schizophrenia (SCZ), and subthreshold psychotic experiences in non-clinical populations is well-established. However, little is known about the relationship between subtypes of trauma and specific symptoms in patients, their siblings, and controls. It is also not clear which variables mediate the relationship between trauma and psychotic symptoms. METHODS Seven hundred and forty-two patients with SCZ, 718 of their unaffected siblings and 1039 controls from three EU-GEI sites were assessed for CT, symptom severity, and cognitive schemas about self/others. CT was assessed with the Childhood Trauma Questionnaire, and cognitive schemas were assessed by The Brief Core Schema Scale. RESULTS Patients with psychosis were affected by CT more than their siblings and controls in all domains. Childhood emotional abuse and neglect were more common in siblings than controls. CT was related to negative cognitive schemas toward self/others in patients, siblings, and controls. We found that negative schemas about self-mediated the relationship between emotional abuse and thought withdrawal and thought broadcasting. Approximately 33.9% of the variance in these symptoms was explained by the mediator. It also mediated the relationship between sexual abuse and persecutory delusions in SCZ. CONCLUSIONS Our findings suggest that childhood abuse and neglect are more common in patients with schizophrenia than their siblings and healthy controls, and have different impacts on clinical domains which we searched. The relationship between CT and positive symptoms seems to be mediated by negative cognitive schemas about self in schizophrenia.

Inflammation and cognitive performance in first-episode schizophrenia spectrum disorders: The moderating effects of childhood trauma. Schizophr Res 2023; 261:185-193.

Abstract
In this study, we aimed to determine whether childhood trauma moderated the relationship between inflammation and cognitive functioning in persons with first-episode schizophrenia spectrum disorders (SSDs). We included data from 92 individuals who participated in the nationwide Early-Stage Schizophrenia Outcome study. These individuals completed the Childhood Trauma Questionnaire, provided a fasting blood sample for high-sensitivity C-reactive protein analysis, and underwent extensive neuropsychological testing. The intervening effects of age, sex, education, smoking status, and body mass index were controlled. Results indicated that childhood trauma levels significantly moderated the relationship between inflammation and four cognitive domains: speed of processing, working memory, visual memory, and verbal memory. Inflammation also predicted verbal memory scores irrespective of childhood trauma levels or the covariates. Upon further exploration, the significant moderation effects appeared to be primarily driven by males. In conclusion, a history of childhood trauma may be an important determinant in evaluating how inflammation relates to the cognitive performance of people with first-episode SSDs, particularly in speed of processing, working memory, visual memory, and verbal memory. We recommend that future researchers examining the effect of inflammation on cognitive functioning in SSDs include trauma as a moderating variable in their models and further examine additional moderating effects of sex.

Abstract
ABSTRACT Psychoticism is a multidimensional personality construct involving odd or eccentric behavior, quasi-psychotic experiences, mistrust, interpersonal detachment, and liability for schizophrenia-spectrum disorders, as well as significant distress. Recent advances suggest it can be understood as a dimension that is continuously distributed in the population, leading to questions about factors that contribute to distress and dysfunction among people with a schizotypal liability. We investigated in a large nonclinical sample of young adults whether associations between psychoticism and psychological distress would increase in the presence of threatening beliefs. In our study ( N = 2127), we found that the association between psychoticism and psychological distress is moderated by threatening beliefs including self-criticism, fear of compassion, and socially prescribed perfectionism. These results suggest that distress increases among people with schizotypal traits in the context of negative beliefs about self and others. We discuss implications for clinical practice and directions for further research.

Abstract
Globally close to 70% of the general population has experienced at least one traumatic life event (TLE). Although child and adulthood exposure to TLEs is considered a risk factor for the subsequent development of psychosis, few studies have examined the association between trauma and psychosis in the African population. We sought to explore the association between TLEs and psychosis in patients with psychotic disorders (N = 254) and individuals without (N = 254). The participants were matched by age and sex. The study was conducted at a national referral hospital, the Life Events Checklist for DSM-5 (LEC-5) was used to obtain data on TLEs, and ethical approval was obtained from the ethics committee. The proportion of those who experienced TLEs was equal among the cases and controls at about 80%. However, more cases reported that the TLEs happened to them (cases 60.3, p = 0.004). After multivariate analysis, the following specific TLEs remained statistically significant.: Physical assault (aOR = 3.66, 95% CI 2.28-5.48), assaults with a weapon (aOR = 5.26, 95% CI 2.15-10.48), sexual assault (aOR = 4.55, 95% CI 1.08-10.48). The sudden death of a loved one (aOR = 2.33, 95% CI 1.15-4.70) and serious injury/harm to others (aOR = 10.53, 95% CI 1.47-89.37).

Abstract
Introduction Persistent negative symptoms (PNS) are described as continuing moderate negative symptoms. More severe negative symptoms have been associated with poor premorbid functioning in both chronic schizophrenia and first episode psychosis patients. Furthermore, youth at clinical high risk (CHR) for developing psychosis may also present with negative symptoms and poor premorbid functioning. The aim of this current study was to: (1) define the relationship between PNS and premorbid functioning, life events, trauma and bullying, previous cannabis use, and resource utilization, and (2) to examine what explanatory variables best predicted PNS. Method CHR participants (N = 709) were recruited from the North American Prodrome Longitudinal Study (NAPLS 2). Participants were divided into two groups: those with PNS (n = 67) versus those without PNS (n = 673). A K-means cluster analysis was conducted to distinguish patterns of premorbid functioning across the different developmental stages. The relationships between premorbid adjustment and other variables were examined using independent samples t-tests or chi square for categorical variables. Results There was significantly more males in the PNS group. Participants with PNS had significantly lower levels of premorbid adjustment in childhood, early adolescence, and late adolescence, compared to CHR participants without PNS. There were no differences between the groups in terms of trauma, bullying, and resource utilization. The non-PNS group had more cannabis use and more desirable and non-desirable life events. Conclusion In terms of better understanding relationships between early factors and PNS, a prominent factor associated with PNS was premorbid functioning, in particular poor premorbid functioning in later adolescence.

Abstract
BACKGROUND A transdiagnostic and contextual framework of 'clinical characterization', combining clinical, psychopathological, sociodemographic, etiological, and other personal contextual data, may add clinical value over and above categorical algorithm-based diagnosis. METHODS Prediction of need for care and health care outcomes was examined prospectively as a function of the contextual clinical characterization diagnostic framework in a prospective general population cohort (n = 6646 at baseline), interviewed four times between 2007 and 2018 (NEMESIS-2). Measures of need, service use, and use of medication were predicted as a function of any of 13 DSM-IV diagnoses, both separately and in combination with clinical characterization across multiple domains: social circumstances/demographics, symptom dimensions, physical health, clinical/etiological factors, staging, and polygenic risk scores (PRS). Effect sizes were expressed as population attributable fractions. RESULTS Any prediction of DSM-diagnosis in relation to need and outcome in separate models was entirely reducible to components of contextual clinical characterization in joint models, particularly the component of transdiagnostic symptom dimensions (a simple score of the number of anxiety, depression, mania, and psychosis symptoms) and staging (subthreshold, incidence, persistence), and to a lesser degree clinical factors (early adversity, family history, suicidality, slowness at interview, neuroticism, and extraversion), and sociodemographic factors. Clinical characterization components in combination predicted more than any component in isolation. PRS did not meaningfully contribute to any clinical characterization model. CONCLUSION A transdiagnostic framework of contextual clinical characterization is of more value to patients than a categorical system of algorithmic ordering of psychopathology.

Abstract
BACKGROUND Traumatic life events (TLEs) are one of the most robust environmental risk factors for the onset of first-episode psychosis (FEP). AIMS To explore TLEs in FEP patients and healthy controls (HC), to analyze gender differences and to examine whether TLEs were associated with sociodemographic, clinical and psychofunctional variables in all FEP sample and split by age. METHODS Descriptive and cross-sectional study. Three hundred and thirty-five FEP and 253 HC were recruited at 16 Spanish mental health research centers. The Traumatic Experiences in Psychiatric Outpatients Questionnaire was administered. RESULTS We found a higher number of TLEs in FEP than in HC, and the proportion of individuals with three or more TLEs was significantly higher in the FEP group. No differences were found in terms of gender and age. There was no relationship between total number of TLEs and psychotic symptomatology and functional outcomes. CONCLUSIONS The number and cumulative TLEs should be taken into account in the detection, epidemiology and process of recovery in FEP.

Abstract
Background People with psychosis experience higher rates of childhood victimisation compared to the general population, which may impact on mental health and recovery. This study aimed to identify childhood victimisation profiles in a clinical sample to inform recommendations for routine care. Methods Participants were 146 adults (ages 19-65 years; M = 42.2) with schizophrenia-spectrum diagnoses reporting trauma. Childhood trauma was assessed using two retrospective measures, and a latent class analysis (LCA) was performed on four trauma types (sexual abuse, emotional abuse, physical abuse and neglect). Multinomial logistic regression investigated demographic differences between the classes. Results Four distinct childhood trauma classes were identified: Emotional abuse/neglect (n = 29); physical abuse (n = 14); sexual abuse (n = 19); and poly-victimisation (n = 84). There were no differences between the classes in terms of age, ethnicity, relationship status, education or current employment (relative risk (RR) = 0.85-1.27, p > 0.05). Participants in the poly-victimisation class were significantly more likely to be female (RR = 0.22-0.28, p < 0.04). Discussion Adults with psychosis, particularly females, are likely to report poly-victimisation in childhood. This highlights the need to comprehensively but concisely assess experiences of abuse and neglect in clinical care, in line with trauma-informed approaches.

Abstract
BACKGROUND Some of the most-studied environmental factors that can contribute to the development of psychosis are the adversities experienced at an early age. Among these, childhood interpersonal trauma (CIT) has been considered especially influential in the onset of the disease. The aim of the study was to explore the relationship between CIT and the first episode of psychosis (FEP), as well as the relationship between CIT and clinical and functional outcomes 3 years after illness onset. METHODS A total of 278 patients with a FEP and 52 healthy controls were studied. Logistic regression analysis was carried out to examine the explained variation by CIT at the beginning of psychosis. Recent stressful events and premorbid adjustment related to CIT, were introduced in path analyses to determine their mediating effects between CIT and the disease and its clinical and functional results. RESULTS Mediation analyses showed that CIT was indirectly associated with belonging to the FEP group through recent stressful events (Effect = 0.981; SE = 0.323; CI = 0.485 to 1.761). Premorbid academic adjustment in late adolescence mediated the relationship between CIT and clinical and functional outcomes, specifically in the measurements of the Scales for Assessment of Positive and Negative Symptoms, in the Brief Psychiatric Rating Scale, and in the Disability Assessment Scale. CONCLUSIONS These findings suggest that early traumatic experiences play an important role in the FEP. Early intervention that promotes good academic adjustment during adolescence and/or avoids retraumatisation could positively impact both the onset and the course of psychotic illness.

Abstract
BACKGROUND There is evidence that environmental and genetic risk factors for schizophrenia spectrum disorders are transdiagnostic and mediated in part through a generic pathway of affective dysregulation. METHODS We analysed to what degree the impact of schizophrenia polygenic risk (PRS-SZ) and childhood adversity (CA) on psychosis outcomes was contingent on co-presence of affective dysregulation, defined as significant depressive symptoms, in (i) NEMESIS-2 (n = 6646), a representative general population sample, interviewed four times over nine years and (ii) EUGEI (n = 4068) a sample of patients with schizophrenia spectrum disorder, the siblings of these patients and controls. RESULTS The impact of PRS-SZ on psychosis showed significant dependence on co-presence of affective dysregulation in NEMESIS-2 [relative excess risk due to interaction (RERI): 1.01, p = 0.037] and in EUGEI (RERI = 3.39, p = 0.048). This was particularly evident for delusional ideation (NEMESIS-2: RERI = 1.74, p = 0.003; EUGEI: RERI = 4.16, p = 0.019) and not for hallucinatory experiences (NEMESIS-2: RERI = 0.65, p = 0.284; EUGEI: -0.37, p = 0.547). A similar and stronger pattern of results was evident for CA (RERI delusions and hallucinations: NEMESIS-2: 3.02, p < 0.001; EUGEI: 6.44, p < 0.001; RERI delusional ideation: NEMESIS-2: 3.79, p < 0.001; EUGEI: 5.43, p = 0.001; RERI hallucinatory experiences: NEMESIS-2: 2.46, p < 0.001; EUGEI: 0.54, p = 0.465). CONCLUSIONS The results, and internal replication, suggest that the effects of known genetic and non-genetic risk factors for psychosis are mediated in part through an affective pathway, from which early states of delusional meaning may arise.

Abstract
Childhood maltreatment (CM) and genetic vulnerability are both risk factors for psychosis, but the relations between them are not fully understood. Guided by the recent identification of genetic risk to CM, this study investigates the hypothesis that genetic risk to schizophrenia also increases the risk of CM and thus impacts psychosis risk. The relationship between schizophrenia polygenetic risk, CM, and psychotic-like experiences (PLE) was investigated in participants from the Utrecht Cannabis Cohort (N = 1262) and replicated in the independent IMAGEN cohort (N = 1740). Schizophrenia polygenic risk score (SZ-PRS) were calculated from the most recent GWAS. The relationship between CM, PRS, and PLE was first investigated using multivariate linear regression. Next, mediation of CM in the pathway linking SZ-PRS and PLE was examined by structural equation modeling, while adjusting for a set of potential mediators including cannabis use, smoking, and neuroticism. In agreement with previous studies, PLE were strongly associated with SZ-PRS (B = 0.190, p = 0.009) and CM (B = 0.575, p < 0.001). Novel was that CM was also significantly associated with SZ-PRS (B = 0.171, p = 0.001), and substantially mediated the effects of SZ-PRS on PLE (proportion mediated = 29.9%, p = 0.001). In the replication cohort, the analyses yielded similar results, confirming equally strong mediation by CM (proportion mediated = 34.7%, p = 0.009). Our results suggest that CM acts as a mediator in the causal pathway linking SZ-PRS and psychosis risk. These findings open new perspectives on the relations between genetic and environmental risks and warrant further studies into potential interventions to reduce psychosis risk in vulnerable people.

Abstract
Adverse childhood experiences (ACEs) can negatively affect social-emotional functioning. The association between individual and cumulative ACEs and social-emotional domains of self-esteem, loneliness, and negotiation in intimate partner relationships has not been explored in low-risk emerging adults, a gap this study aims to fill. An online survey was administered to undergraduate emerging adults, ages 18 to 25 years (Mage = 19.73, SD = 1.83; N = 436; 20.60% Hispanic; 63.80% female). The ACEs Survey, Child Abuse Potential Inventory, and Conflict Tactics Scale-2nd Edition were used. Three multivariate ordinary least squares regressions were run, each including predictors significant in bivariate analyses and outcomes of self-esteem, loneliness, and negotiation for each regression. Emotional abuse, B = -.20, p < .01; emotional neglect, B = -.21, p < .001; and substance using family member, B = -.12, p < .05, were negatively associated with self-esteem; emotional neglect, B = .11, p < .01, and cumulative ACEs, B = .16, p < .01, were positively associated with loneliness; and incarcerated family member was positively associated with negotiation, B = .12, p < .05. Overall, these findings suggest that individual ACEs associated with environmental instability (e.g., emotional abuse) are strong predictors of social-emotional outcomes, relative to ACEs associated with more direct physical harm (e.g., sexual abuse).

Abstract
Background Numerous studies found robust associations between psychosis and posttraumatic stress disorder (PTSD), but few have examined the relationships between psychosis and recently formulated ICD-11 Complex PTSD (CPTSD). Further, no known study has examined the effects of different traumatic life events on CPTSD and psychotic-like symptoms in a manner that permits gender-specific effects to be identified. Objective Using a nationally representative sample of 1,020 Irish adults, we examined gender-differences in (a) psychotic-like symptoms, CPTSD, and exposure to 21 different traumatic life events, and (b) the unique associations between different traumas with CPTSD and Psychosis. Method Bivariate analyses and structural equation modelling were performed. Results Consistent with the literature, no gender differences were observed in psychotic-like symptoms. Females reported slightly higher levels of CPTSD and were more likely to be exposed to sexual and emotional abuse, whereas men reported greater exposure to physical violence, accidents, and disasters. Psychosis symptoms were explained by trauma exposure to a considerate degree and at a level similar to CPTSD; a moderate correlation was also found between CPTSD and Psychosis. Physical/emotional neglect was the only traumatic life event that significantly and most strongly predicted both conditions. Two gender-specific associations between different traumatic life events and CPTSD and Psychosis were identified out of the 42 possible effects modelled. Conclusions The present investigation provides initial evidence that psychotic-like symptoms and CPTSD are moderately correlated constructs in the general population. Results also highlight the importance of conducting a detailed assessment of trauma history for all clients presenting with symptoms of CPTSD, psychosis, or both.

Early Interv Psychiatry 2021; 15:1335-1342. [PMID: 33289325 DOI: 10.1111/eip.13086] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Revised: 09/14/2020] [Accepted: 11/14/2020] [Indexed: 11/29/2022]
Abstract
AIM Premorbid substance use is widely recognized as a crucial factor in early psychosis. We explored the effects of childhood/adolescent adversity on premorbid tobacco, alcohol, and cannabis use. We hypothesized that adversity in childhood would be associated with an increased likelihood of use, and amount of intake, of tobacco, alcohol, and cannabis. We analysed which domains of adversity have the greatest impact. METHODS First-episode psychosis patients were enrolled from six inpatient psychiatric units in Atlanta, Georgia and Washington, D.C. Premorbid substance use was thoroughly measured, and childhood/adolescent adversity was rated using 14 scales/subscales. Factor analysis was used to reduce these scales/subscales to the three domains of adversity (termed Violence and Environmental Adversity, Interpersonal Abuse, and Neglect and Lack of Connectedness). Regression analyses determined associations between adversity domains and premorbid substance use. RESULTS Our sample (n = 247) primarily consisted of African Americans (86.2%) and males (74.5%). Violence and Environmental Adversity was significantly associated with five of six substance use variables and marginally associated with the sixth. Interpersonal Abuse was unassociated with substance use, and Neglect and Lack of Connectedness was associated only with a lower likelihood cannabis use. When Violence and Environmental Adversity results were stratified by gender, effects on tobacco use and amount of tobacco use were stronger among females. CONCLUSIONS Childhood/adolescent trauma and adversity have meaningful associations with premorbid substance use in first-episode psychosis patients. First-episode psychosis and clinical high-risk treatment settings may benefit from expanding the assessment of childhood/adolescent adversity to include factors pertaining to violence exposure and adversities beyond abuse and neglect.

Early Interv Psychiatry 2021; 15:1154-1166.

Abstract
AIM Prior research has consistently demonstrated a relationship between childhood trauma (CT) exposure and an increased risk of developing psychotic-like experiences (PLE) and disorders. Studying the link between CT and PLE in non-clinical populations with or without genetic risk factors could help elucidate the etiopathogeny of psychotic disorders, by removing the effect of confounding variables related to psychotic-spectrum illnesses. METHOD A total of 60 non-affected siblings of patients with schizophrenia and 75 controls (aged 18-35 years) participated in a cross-sectional survey. The Positive Subscale of Community Assessment of Psychotic Experiences (CAPE) and the CT Questionnaire were used. RESULTS We found no significant difference with regard to positive dimension of the CAPE between the two groups. Siblings have reported higher CAPE negative symptoms scores than controls (27.9 vs 24.2; P = .015), and more emotional abuse and physical neglect during childhood than controls. After controlling for demographic and psychosocial variables, sexual abuse, emotional neglect and physical neglect were positively related to positive psychotic symptoms in the control group, whereas no dimension of CT has been linked to these symptoms in the sibling group. CONCLUSION The link between CT and psychosis seems to be complex, not only dependent on genetic vulnerability or early environmental factors shared by siblings of patients with psychotic disorders, but also several other confounding factors, including other psychopathological symptoms. Prevention strategies for individuals at genetic risk of psychosis should pay particular attention to CT as a potential predictor of sub-clinical depression and psychosis.

Abstract
BACKGROUND Although hallucinations have been studied in terms of prevalence and its associations with psychopathology and functional impairment, very little is known about sensory modalities other than auditory (i.e. haptic, visual and olfactory), as well the incidence of hallucinations, factors predicting incidence and subsequent course. METHODS We examined the incidence, course and risk factors of hallucinatory experiences across different modalities in two unique prospective general population cohorts in the same country using similar methodology and with three interview waves, one over the period 1996-1999 (NEMESIS) and one over the period 2007-2015 (NEMESIS-2). RESULTS In NEMESIS-2, the yearly incidence of self-reported visual hallucinations was highest (0.33%), followed by haptic hallucinations (0.31%), auditory hallucinations (0.26%) and olfactory hallucinations (0.23%). Rates in NEMESIS-1 were similar (respectively: 0.35%, 0.26%, 0.23%, 0.22%). The incidence of clinician-confirmed hallucinations was approximately 60% of the self-reported rate. The persistence rate of incident hallucinations was around 20-30%, increasing to 40-50% for prevalent hallucinations. Incident hallucinations in one modality were very strongly associated with occurrence in another modality (median OR = 59) and all modalities were strongly associated with delusional ideation (median OR = 21). Modalities were approximately equally strongly associated with the presence of any mental disorder (median OR = 4), functioning, indicators of help-seeking and established environmental risk factors for psychotic disorder. CONCLUSIONS Hallucinations across different modalities are a clinically relevant feature of non-psychotic disorders and need to be studied in relation to each other and in relation to delusional ideation, as all appear to have a common underlying mechanism.

Abstract
BACKGROUND Traumatic stressful events (TSEs) are among the most studied risk factors for subsequent schizotypal symptoms. However, specificity and aggregate effects of trauma exposure on schizotypal symptoms remain unclear. This study investigates these relationships among a community-based sample of US adolescents. MATERIAL AND METHODS A sub-sample of 426 adolescents (51.6% female) from the Philadelphia Neurodevelopmental Cohort study were selected for longitudinal follow-up based on presence (n = 209) or absence (n = 217) of psychosis spectrum symptoms (PSS). At baseline, they completed assessments of demographic, TSEs, other psychopathology (e.g., PSS, anxiety, depression, and behavioral disorder) and family history of psychopathology. Schizotypal symptom dimensions (cognitive-perceptual, interpersonal and disorganized) were evaluated approximately two years later. RESULTS More than half of adolescents experienced at least one type of TSE. Adolescents with assaultive trauma reported about 1.5 times as many symptoms on all three schizotypal symptom dimensions, compared to adolescents with non-assaultive TSE, adjusting for demographic and family history variables. No statistical significance was found after further adjusting for other baseline psychopathology (p > 0.05). There was a significant aggregate effect of TSEs on cognitive-perceptual symptoms with small effect size (p < 0.001, Cohen's f2 = 0.034). CONCLUSIONS We found evidence of an association between aggregate TSEs and cognitive-perceptual symptoms, but trauma type was not associated with schizotypal symptom dimensions when controlling for potential confounders. Our findings highlight the importance of considering aggregate TSE effects and potential confounds when examining associations between TSEs and schizotypy. Trauma and psychosis spectrum screening may be important in the effort to provide trauma-informed care.

Abstract
AIMS Childhood trauma is associated with an elevated risk for psychosis, but the psychological mechanisms involved remain largely unclear. This study aimed to investigate emotional and psychotic stress reactivity in daily life as a putative mechanism linking childhood trauma and clinical outcomes in individuals at ultra-high-risk (UHR) for psychosis. METHODS Experience sampling methodology was used to measure momentary stress, affect and psychotic experiences in the daily life of N = 79 UHR individuals in the EU-GEI High Risk Study. The Childhood Trauma Questionnaire was used to assess self-reported childhood trauma. Clinical outcomes were assessed at baseline, 1- and 2-year follow-up. RESULTS The association of stress with positive (β = -0.14, p = 0.010) and negative affect (β = 0.11, p = 0.020) was modified by transition status such that stress reactivity was greater in individuals who transitioned to psychosis. Moreover, the association of stress with negative affect (β = 0.06, p = 0.019) and psychotic experiences (β = 0.05, p = 0.037) was greater in individuals exposed to high v. low levels of childhood trauma. We also found evidence that decreased positive affect in response to stress was associated with reduced functioning at 1-year follow-up (B = 6.29, p = 0.034). In addition, there was evidence that the association of childhood trauma with poor functional outcomes was mediated by stress reactivity (e.g. indirect effect: B = -2.13, p = 0.026), but no evidence that stress reactivity mediated the association between childhood trauma and transition (e.g. indirect effect: B = 0.14, p = 0.506). CONCLUSIONS Emotional and psychotic stress reactivity may be potential mechanisms linking childhood trauma with clinical outcomes in UHR individuals.

Abstract
The influence of psychosocial stressors on psychosis risk has usually been studied in isolation and after the onset of the disorder, potentially ignoring important confounding relationships or the fact that some stressors that may be the consequence of the disorder rather than preexisting. The study of subclinical psychosis could help to address some of these issues. In this study, we investigated whether there was (i) an association between dimensions of subclinical psychosis and several psychosocial stressors including: childhood trauma, self-reported discrimination experiences, low social capital, and stressful life experiences, and (ii) any evidence of environment-environment (ExE) interactions between these factors. Data were drawn from the EUGEI study, in which healthy controls (N = 1497) and siblings of subjects with a psychotic disorder (N = 265) were included in six countries. The association between psychosocial stressors and subclinical psychosis dimensions (positive, negative and depressive dimension as measured by the Community Assessment of Psychic Experiences (CAPE) scale) and possible ExE interactions were assessed using linear regression models. After adjusting for sex, age, ethnicity, country, and control/sibling status, childhood trauma (β for positive dimension: 0.13, negative: 0.49, depressive: 0.26) and stressful life events (positive: 0.08, negative: 0.16, depressive: 0.17) were associated with the three dimensions. Lower social capital was associated with the negative and depression dimensions (negative: 0.26, depressive: 0.13), and self-reported discrimination experiences with the positive dimension (0.06). Our findings are in favor of independent, cumulative and non-specific influences of social adversities in subclinical psychosis in non-clinical populations, without arguments for E × E interactions.

Abstract
OBJECTIVE Early life adversity is suspected to play an important role for onset and course of psychosis, but its relationship with longer-term clinical outcome is not entirely clear. In this longitudinal study, we investigated the impact of childhood trauma (CT) on positive and negative symptom remission in first episode psychosis (FEP) patients over two years. METHODS A total of 210 FEP patients were assessed with the Childhood Trauma Questionnaire. Patients reporting moderate to severe trauma (CT; N = 114; 54.3%) were compared to those without trauma (N-CT; N = 96; 45.7%). Positive (PSR) and negative symptom remission (NSR) were determined monthly over 24 months following established criteria using the Scale for Assessment of Positive Symptoms and the Scale for Assessment of Negative Symptoms. Global Functioning was evaluated at baseline and 24 months of follow-up. RESULTS Compared to N-CT patients, CT patients had achieved significantly lower rates of PSR at 12 months and significantly lower rates of NSR at 24 months. A dose-response relationship was observed between the number of trauma categories fulfilled and the number of patients not achieving PSR and NSR at these time points. Higher trauma scores were significantly associated with poor functioning and higher positive and negative symptom severity at 24 months, but not at baseline and 12 months of follow-up. CONCLUSION Differential effects of CT on clinical outcome may not be apparent at psychosis onset, but only become evident through poor symptomatic remission and general functioning over time. Targeted diagnostic and therapeutic efforts after illness onset might limit these detrimental consequences.

Abstract
Despite the accepted link between childhood abuse and positive psychotic symptoms, findings between other adversities, such as neglect, and the remaining dimensions in people with psychosis have been inconsistent, with evidence not yet reviewed quantitatively. The aim of this study was to systematically examine quantitatively the association between broadly defined childhood adversity (CA), abuse (sexual/physical/emotional), and neglect (physical/emotional) subtypes, with positive, negative, depressive, manic, and disorganized dimensions in those with psychosis. A search was conducted across EMBASE, MEDLINE, PsychINFO, and Cochrane Libraries using search terms related to psychosis population, CA, and psychopathological dimensions. After reviewing for relevance, data were extracted, synthesized, and meta-analyzed. Forty-seven papers were identified, including 7379 cases across 40 studies examining positive, 37 negative, 20 depressive, 9 disorganized, and 13 manic dimensions. After adjustment for publication bias, general adversity was positively associated with all dimensions (ranging from r = 0.08 to r = 0.24). Most forms of abuse were associated with depressive (ranging from r = 0.16 to r = 0.32), positive (ranging from r = 0.14 to r = 0.16), manic (r = 0.13), and negative dimensions (ranging from r = 0.05 to r = 0.09), while neglect was only associated with negative (r = 0.13) and depressive dimensions (ranging from r = 0.16 to r = 0.20). When heterogeneity was found, it tended to be explained by one specific study. The depressive dimension was influenced by percentage of women (ranging from r = 0.83 to r = 1.36) and poor-quality scores (ranging from r = -0.21 and r = -0.059). Quality was judged as fair overall. Broadly defined adversity and forms of abuse increase transdimensional severity. Being exposed to neglect during childhood seems to be exclusively related to negative and depressive dimensions suggesting specific effects.

Effects of polygenic risk score, childhood trauma and resilience on depressive symptoms in Chinese adolescents in a three-year cohort study. J Affect Disord 2021; 282:627-636.

Abstract
BACKGROUND Polygenic risk score (PRS) is a method of revealing multiple genes effect. The study of PRS and childhood trauma (CT) and resilience on adolescent depressive symptoms are fewer reported, especially the functional mechanism of resilience among them. METHODS 718 Chinese adolescents aged 10-14 years were surveyed including CT, resilience, depressive symptoms, and phenotype data in three years of the cohort study. PRS was calculated by the weighted accumulation effects of alleles on depressive symptoms. Their relationships were analyzed by the mediation and moderation models. RESULTS PRS and CT were risk factors for depressive symptoms. Interaction (PRS × CT) on depressive symptoms had no statistical significance. Resilience acted as the protective mediator from CT (emotional abuse, emotional neglect, physical neglect) to depressive symptoms and moderator from CT (emotional abuse) to depressive symptoms. LIMITATIONS The sample size was a little small so that the inference were drawn prudently. Except gene data, other were collected by self-reported questionnaire instruments which inevitably brought recall bias. CONCLUSIONS PRS and CT could have adverse impact on depressive symptoms, resilience could alleviate these risk effects as a moderator and a mediator. The findings have important implications for prevention and intervention in adolescent depressive symptoms.

Abstract
Childhood maltreatment (CM) is a risk factor for numerous mental disorders. However, the specificity of CM types in mental disorders is still being discussed. The present study examined the prevalence of five CM types in patients with schizophrenia/schizoaffective disorder (SZ; n = 107), bipolar disorder (BD; n = 103), depression (MDD; n = 604; with the two subgroups Persistent Depressive Disorder (PDD) and non-chronic MDD), and in healthy controls (HC; n = 715). Additionally, associations between CM types, symptom severity, and age of onset were investigated. The prevalence of all CM types was higher in the patient groups compared to HC. Emotional neglect, emotional abuse, and physical neglect were reported most frequently in all groups. Notably, patients with PDD reported more CM of all types than patients with non-chronic MDD. The severity of depression was associated with emotional abuse and neglect; anxiety with emotional abuse, emotional neglect, and sexual abuse; positive SZ symptoms with physical neglect; negative symptoms with emotional and physical neglect; and mania with sexual abuse and physical neglect. CM was associated with a younger age of onset in MDD and BD. The high prevalence of CM in patients with severe mental disorders highlights the importance of considering this issue in the treatment of such patients.

Abstract
BACKGROUND Positive early life experiences may help prevent depression later in life. We examined the accumulated benefit, timing, and trajectories of positive parental involvement in childhood in association with incident depression in early adulthood. METHODS Prospectively assessed Avon Longitudinal Study of Parents and Children (ALSPAC) data (n = 7120) were analyzed. Overall and developmental stage-specific parental involvement scores were estimated from multiple measures from birth to age 7 years. Trajectory groups of parental involvement were derived via latent class growth analysis. At 18 years, depression cases were identified with diagnostic instruments. Multiple imputation was used to handle missingness. We constructed logistic regression models with potential confounders adjusted. RESULTS Participants from trajectory groups with higher average parenting scores over time had 30% to 40% lower odds of developing depression in early adulthood than participants from the group with the lowest average parenting score over time. However, the relationship became non-significant when all covariates were adjusted. A one-unit increase in the overall parenting score corresponded to 12% lower odds of developing depression (adjusted OR=0.88 [0.79-0.98]). Protective effects on incident depression in early adulthood from parental involvement in school age (5-7 years), and not at other ages, were observed (OR=0.87 [0.77-0.99] for a one-unit increase in the parenting score at school age). However, the relationship became non-significant when all covariates were adjusted (OR=0.91 [0.80-1.03]). LIMITATIONS Measurements of parental involvement were only based on maternal report. The study has limited generalizability to other racial/ethnic groups. CONCLUSION Higher level of parental involvement during childhood lowers the risk of developing depression in early adulthood. These results suggest positive early life experiences may promote mental health across the life course.

Abstract
Childhood trauma exposure has been associated with poorer treatment outcomes in schizophrenia. Most studies to date have been conducted in naturalistic settings in which the outcome may have been mediated by factors such as poor adherence and substance abuse. We compared the effects of high vs low childhood trauma exposure on the treatment response over 24 months in 78 patients with first-episode schizophrenia spectrum disorders who received standardised treatment with a long acting injectable antipsychotic. Compared to the low childhood trauma group (n = 37), the high childhood trauma group (n = 41) received higher doses of antipsychotic medication and were less likely to achieve remission. When age, sex and cannabis use were controlled for, patients with high levels of childhood trauma had a slower treatment response for positive and disorganized symptom domains, although differences did not differ significantly at 24 months. While there were no differences in functional outcomes, self-rated quality of life was the domain that most clearly differentiated the high and low childhood trauma groups. High childhood trauma exposure was associated with lower quality of life scores at baseline, a lesser degree of improvement with treatment, and lower quality of life scores at 24 months.

Abstract
BACKGROUND There is a consensus that adoptees and immigrants both experience more mental health problems than their peers. The two groups share many risk factors for psychosis, but an increased risk for psychotic illness has only been demonstrated for immigrants. AIMS The aim of this review is to describe psychosis risk factors in adoptees, with a focus on difficulties with identity formation, identification with in-groups, attachment to parents, and coping with loss and with discrimination. METHOD The literature in these five areas is reviewed as it pertains to adoption and psychosis. RESULTS There are no clear findings because the relevant studies have not been done, but the literature suggests that adopted children face challenges very similar to those of immigrants to a new country. CONCLUSION The immigration field and the adoption field have much to learn from each other. It is recommended that a prevention strategy analogous to increased neighbourhood ethnic density be implemented with adoptees - that they be intentionally exposed from early childhood and throughout adolescence to age peers who share a similar background and with whom they can readily identify. It is also recommended that immigrants be welcomed into their host country with the same open arms as adoptive parents welcome their new children.

Abstract
BACKGROUND Research on environmental and individual risk-factors in patients with a psychotic disorder and co-occurring obsessive-compulsive symptoms (OCS) is limited. OBJECTIVE This study aimed to examine the role of childhood trauma and coping on the occurrence of OCS in patients with a psychotic disorder and on a subclinical level in siblings. PARTICIPANTS AND SETTING 626 patients and 638 siblings from the Genetic Risk and Outcome of Psychosis (GROUP) study were included in the current study. METHODS Differences between patients and siblings with and without OCS were analyzed with between-group comparisons. Mediation analyses investigated the effect of coping on the association between trauma and OCS severity. RESULTS Patients and siblings with OCS reported more childhood traumatic events, particularly sexual (OR = 1.62 / 3.26) and emotional (OR = 1.47 / 2.04) abuse compared to those without OCS. Both patients (d = 0.69) and siblings (d = 0.49) with co-occurring OCS showed a higher tendency for dysfunctional passive coping strategies compared to the group without OCS. The tendency for passive coping mediated the association between sexual and emotional abuse and OCS severity in patients. CONCLUSIONS Results imply that childhood trauma is associated with the presence of co-occurring OCS. Enhancing active coping strategies might have a beneficial effect in the prevention and treatment of co-occurring OCS in patients with psychotic disorders.

Abstract
OBJECTIVES To examine ontological insecurity as a predictor of positive psychotic-like experiences (PLEs) relative to concepts of childhood trauma, parental bonding, and adult attachment style. METHODS A nonclinical sample (N = 298) completed the Ontological Insecurity Scale (OIS-34), a new measure of ontological insecurity, along with measures of the above concepts. RESULTS The OIS-34 accounted for a significantly greater proportion of unique variance in positive PLEs than any other theoretical variable. Anxious and avoidant adult attachment were also strongly associated with positive PLEs, but these relationships were mediated by the OIS-34, ceasing to be significant once this latter variable entered the hierarchical regression equation. CONCLUSIONS The results are consistent with R. D. Laing's theory that ontological insecurity plays a significant role in psychosis. Moreover, the results suggest that this concept may mediate the established relationship between anxious/avoidant adult attachment and positive PLEs. Implications for psychological approaches to clinical psychosis are discussed.

Abstract
BACKGROUND Characterizing the link between childhood trauma and adult neurocognitive function in psychosis is crucial for improving the fields understanding of how early environmental risk factors impact the presentation of the disorder. To date, the literature has been inconsistent: meta-analytic synthesis is lacking, and it is unclear whether specific cognitive functions are affected. METHODS A meta-analysis was performed on a total of 3315 subjects with a psychotic disorder. The links between childhood trauma, overall neurocognitive function, and four cognitive subdomains (working memory, executive function, verbal/visual memory, and attention/processing speed) were examined. Relevant sample characteristics and methodological moderators were tested. The strength of the association between trauma and overall neurocognition in individuals with psychotic disorders was also compared to that of healthy controls. RESULTS Among individuals with psychotic disorders, there was a significant association between overall cognition and childhood trauma, r = -.055; 95% CI = -0.09, -0.02, P = .002. There was also a modest, negative relationship between childhood trauma and working memory, r = -.091; 95% CI = -0.15, -0.03, P = .002. Moderators did not have a significant effect on these analyses. Further, the association between childhood trauma and neurocognition was significantly stronger in healthy controls compared to patients with a psychotic disorder. CONCLUSION A small negative association was found between overall cognition and childhood trauma in individuals with psychotic disorders. Results suggest the association is less strong for individuals with a psychotic disorder compared to healthy populations. Findings are informative for prominent etiological models of psychosis.

Abstract
There is an increasing focus on trauma within forensic services. This study aimed to investigate exposure to trauma among a high secure male forensic population. Based on the Childhood Trauma Questionnaire (CTQ) and the Trauma History Questionnaire (THQ) data capture sheets were developed. Patients' own offending behaviour was included as a source of potential trauma. Records for all patients placed within the hospital (n = 194) were reviewed. All patients had been exposed to a traumatic event over the lifespan, with 75% having been exposed to trauma during childhood. Sixty-five percent of patients had experienced more than one type of trauma during childhood; the mean number of trauma types experienced during this period being 2.31. In adulthood 63% had been exposed to one trauma type while 29% had been exposed to two or more trauma types. No significant difference was found between those with and those without childhood trauma histories on hospital variables including admission length, seclusion and incidents. The implications of these results in the context of adopting a trauma informed care approach to treatment in forensic settings are discussed, and recommendations for future clinical and research directions are made.

Lee EE, Martin AS, Tu X, Palmer BW, Jeste DV. Childhood Adversity and Schizophrenia: The Protective Role of Resilience in Mental and Physical Health and Metabolic Markers. J Clin Psychiatry 2019; 79:17m11776. [PMID: 29701938 PMCID: PMC6464641 DOI: 10.4088/jcp.17m11776] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2017] [Accepted: 01/08/2018] [Indexed: 12/16/2022]
Abstract
OBJECTIVE To determine the impact of childhood adversity and current (adulthood) resilience on mental and physical health and markers of metabolic function among adults with schizophrenia and nonpsychiatric comparison participants (NCs). METHODS We conducted a cross-sectional study of 114 participants with schizophrenia (DSM-IV-TR criteria) and 101 NCs aged 26-65 years during 2012-2017. Sociodemographic, clinical, and laboratory measures were examined. Childhood Trauma Questionnaire was used to retrospectively assess emotional abuse/neglect, physical abuse/neglect, and sexual abuse experienced during childhood. Connor-Davidson Resilience Scale was employed to measure resilience. RESULTS Persons with schizophrenia reported more severe childhood trauma, lower resilience, and worse mental and physical health and had worse metabolic biomarker levels than NCs. Trauma severity correlated with worse depression in the NCs (r = 0.34), but not in the schizophrenia group (r = 0.02). In both groups, trauma severity was associated with worse physical well-being, higher fasting insulin levels, and greater insulin resistance (P ≤ .02). Notably, resilience appeared to counteract effects of trauma and diagnosis on mental and physical health. The schizophrenia subgroup with high resilience and severe trauma reported mental and physical well-being and had glycosylated hemoglobin levels and insulin resistance scores that were comparable to those of NCs with low resilience and severe trauma. CONCLUSIONS To our knowledge, this is the first study to quantitatively assess effects of both childhood trauma and resilience in schizophrenia on health, notably metabolic function. Interventions to bolster resilience in the general population and in people with schizophrenia may improve outcomes for those with a history of childhood adversity.

Abstract
BACKGROUND Evidence suggests that cannabis use, childhood adversity, and urbanicity, in interaction with proxy measures of genetic risk, may facilitate onset of psychosis in the sense of early affective dysregulation becoming 'complicated' by, first, attenuated psychosis and, eventually, full-blown psychotic symptoms. METHODS Data were derived from three waves of the second Netherlands Mental Health Survey and Incidence Study (NEMESIS-2). The impact of environmental risk factors (cannabis use, childhood adversity, and urbanicity) was analyzed across severity levels of psychopathology defined by the degree to which affective dysregulation was 'complicated' by low-grade psychotic experiences ('attenuated psychosis' - moderately severe) and, overt psychotic symptoms leading to help-seeking ('clinical psychosis' - most severe). Familial and non-familial strata were defined based on family history of (mostly) affective disorder and used as a proxy for genetic risk in models of family history × environmental risk interaction. RESULTS In proxy gene-environment interaction analysis, childhood adversity and cannabis use, and to a lesser extent urbanicity, displayed greater-than-additive risk if there was also evidence of familial affective liability. In addition, the interaction contrast ratio grew progressively greater across severity levels of psychosis admixture (none, attenuated psychosis, clinical psychosis) complicating affective dysregulation. CONCLUSION Known environmental risks interact with familial evidence of affective liability in driving the level of psychosis admixture in states of early affective dysregulation in the general population, constituting an affective pathway to psychosis. There is interest in decomposing family history of affective liability into the environmental and genetic components that underlie the interactions as shown here.

Abstract
BACKGROUND Childhood trauma increases the risk of schizophrenia, yet the role of adult sexual assault in the course of schizophrenia is unknown. This study aims to examine the associations between substance use and sexual assault severity characteristics with the course of schizophrenia among adult sexual assault victims using an epidemiologic study design. METHODS Sexual assault data on all individuals received from 2000 to 2010 (N = 2147) at the Center for Care of Sexual Assault Victims at Wolfson Medical Center, the largest medical center for sexual assault victims in the country, were merged with the Israel National Psychiatric Case Registry, that consisted of lifetime psychiatric hospitalizations of schizophrenia (birth to 6 years post-assault). The associations between substance use and adult sexual assault severity characteristics with hospitalizations were quantified using recurrent events Cox modeling. RESULTS Schizophrenia with sexual assault survivors occurred in 117 persons. Cox modeling showed that recurrent psychiatric hospitalizations were associated with younger age, sexual assault at older age, previous diagnosis of psychosis, and drug use shortly before or during the assault. Other assault characteristics (number of assailants, means of subdual, penetration type, perpetrator violence, physical injury of the victim) and immediacy of seeking help had a null association with the course of psychiatric hospitalization. These results replicated in two sensitivity analyses. CONCLUSIONS Substance use among victims of sexual assault was associated with an exacerbated course of schizophrenia, pointing to a possibly modifiable risk factor that should be targeted in prevention, assessment, treatment formulation and implementation.

Abstract
BACKGROUND Psychotic experiences (PEs) may predict a range of common, non-psychotic disorders as well as psychotic disorders. In this representative, general population-based cohort study, both psychotic and non-psychotic disorder outcomes of PE were analysed, as were potential moderators. METHODS Addresses were contacted in a multistage clustered probability sampling frame covering 11 districts and 302 neighbourhoods at baseline (n = 4011). Participants were interviewed with the Composite International Diagnostic Interview (CIDI) both at baseline and at 6-year follow-up. Participants with PE at baseline were clinically re-interviewed with the SCID-I at follow-up. The role of socio-demographics, characteristics of PE, co-occurrence of mood disorders and family history of mental disorders were tested in the association between baseline PE and follow-up diagnosis. RESULTS In the participants with baseline PE, the psychotic disorder diagnosis rate at follow up was 7.0% - much lower than the rates of DSM-IV mood disorders without psychotic features (42.8%) and other non-psychotic disorders (24.1%). Within the group with baseline PE, female sex, lower socio-economic status, co-occurrence of mood disorders, family history of a mental disorder and persistence of PE predicted any follow-up DSM diagnosis. Furthermore, onset of psychotic v. non-psychotic disorder was predicted by younger age (15-30 years), co-presence of delusional and hallucinatory PE and family history of severe mental illness. CONCLUSION The outcome of PE appears to be a consequence of baseline severity of multidimensional psychopathology and familial risk. It may be useful to consider PE as a risk indicator that has trans-diagnostic value.

Abstract
The aims of the present study were to investigate the dimensions of childhood trauma (CT) in patients with schizophrenia, and to predict suicidal risk (e.g., current suicidal ideation and lifetime suicide attempts) by CT dimensions and clinical factors (positive and negative symptoms and depression). Eighty-two inpatients with schizophrenia completed the Childhood Trauma Questionnaire-Short Form (CTQ-SF), the Beck Depression Inventory-II (BDI-II), and the Beck Scale for Suicide Ideation (BSSI); they were also administered the Positive and Negative Syndrome Scale (PANSS).The presence of lifetime suicide attempts was assessed by structured diagnostic clinical interview. Patients with lifetime suicide attempts scored higher on sexual abuse than those without attempts after controlling for depression severity. Patients with high suicidal risk had higher scores on physical neglect than those without high risk after controlling for depression severity. Patients with high CT had higher scores on negative and positive symptoms, current suicidal ideation, and depression than those with low CT. Logistic regression analyses indicated that sexual abuse was a unique predictor of lifetime suicide attempts, and that physical neglect and depression were unique predictors of current suicidal ideation. These findings indicate that patients with schizophrenia who have experienced CT may be at increased risk for suicide.

Abstract
BACKGROUND Childhood maltreatment is a transdiagnostic risk factor for later psychopathology and has been associated with altered brain circuitry involved in the processing of threat and safety. Examining threat generalization mechanisms in young adults with childhood maltreatment and psychiatric symptoms may elucidate a pathway linking early-life adversities to the presence of subclinical psychopathology. METHODS We recruited youth aged 16–25 years with subclinical psychiatric symptomatology and healthy controls. They were dichotomized into 2 groups: 1 with a high level of childhood maltreatment (n = 58) and 1 with no or a low level of childhood maltreatment (n = 55). Participants underwent a functional MRI threat generalization paradigm, measuring self-reported fear, expectancy of an unconditioned stimulus (US) and neural responses. RESULTS We observed interactions between childhood maltreatment and threat generalization indices on subclinical symptom load. In individuals reporting high levels of childhood maltreatment, enhanced generalization in self-reported fear and US expectancy was related to higher levels of psychopathology. Imaging results revealed that in the group with high levels of childhood maltreatment, lower activation in the left hippocampus during threat generalization was associated with a higher symptom load. Associations between threat generalization and psychopathology were nonsignificant overall in the group with no or low levels of childhood maltreatment. LIMITATIONS The data were acquired in a cross-sectional manner, precluding definitive insight into the causality of childhood maltreatment, threat generalization and psychopathology. CONCLUSION Our results suggest that threat generalization mechanisms may moderate the link between childhood maltreatment and subclinical psychopathology during emerging adulthood. Threat generalization could represent a vulnerability factor for developing later psychopathology in individuals being exposed to childhood maltreatment.

Abstract
INTRODUCTION Childhood abuse and neglect are risk factors for psychotic symptoms. Early adversities may contribute to alterations in neuro/social cognition, which in turn is associated with psychosis. This study explored the possible mediating/moderating role of neuro/social cognition between childhood abuse and neglect on the one hand, and psychotic symptoms on the other. METHOD The sampling frame was 1.119 patients with a psychotic disorder. Childhood adversity was evaluated with the Dutch version of the Childhood Trauma Questionnaire. Psychotic symptoms were assessed with the Positive and Negative Syndrome Scale. Verbal learning-memory, attention-vigilance, working memory, information processing speed, reasoning-problem solving were evaluated as measures of neurocognition using the Word Learning Task, the Continuous Performance Test, the Wechsler Adult Intelligence Scale 3rd. Mentalization was evaluated as a measure of social cognition using the Hinting Task. Correlation, mediation, moderation, 95% Bias Corrected and accelerated (BCaCI) bootstrapped analyses were performed, considering possible sex differences. RESULTS In male psychotic patients, attention and vigilance mediated the association between childhood neglect and negative symptoms (indirect effect: 0.18, BCaCI: 0.03-0.54), disorganization (indirect effect: 0.26, BCaCI: 0.05-0.61), excitement (indirect effect: 0.07, BCaCI: 0.004-0.23); mentalization mediated the association between childhood neglect and negative symptoms (indirect effect: 0.21, BCaCI: 0.02-0.51), excitement (indirect effect: 0.07, BCaCI: 0.01-0.20) disorganization (indirect effect: 0.29, BCaCI: 0.02-0.64); working memory mediated the association between childhood abuse and disorganization (indirect effect: 0.28, BCaCI: 0.05-0.57), excitement (indirect effect: 0.08, BCaCI: 0.01-0.20), emotional distress (indirect effect: 0.10, BCaCI: 0.01-0.27). DISCUSSION In psychotic disorder, sex-specific mediation of neurocognition and mentalization may exist in the association between childhood adversity and psychotic symptoms.

Abstract
BACKGROUND The extent to which exposure to childhood sexual and physical abuse increases the risk of psychotic experiences in adulthood is currently unclear.AimsTo examine the relationship between childhood sexual and physical abuse and psychotic experiences in adulthood taking into account potential confounding and time-dynamic covariate factors. METHOD Data were from a cohort of 1265 participants studied from birth to 35 years. At ages 18 and 21, cohort members were questioned about childhood sexual and physical abuse. At ages 30 and 35, they were questioned about psychotic experiences (symptoms of abnormal thought and perception). Generalised estimating equation models investigated covariation of the association between abuse exposure and psychotic experiences including potential confounding factors in childhood (socioeconomic disadvantage, adverse family functioning) and time-dynamic covariate factors (mental health, substance use and life stress). RESULTS Data were available for 962 participants; 6.3% had been exposed to severe sexual abuse and 6.4% to severe physical abuse in childhood. After adjustment for confounding and time-dynamic covariate factors, those exposed to severe sexual abuse had rates of abnormal thought and abnormal perception symptoms that were 2.25 and 4.08 times higher, respectively than the 'no exposure' group. There were no significant associations between exposure to severe physical abuse and psychotic experiences. CONCLUSIONS Findings indicate that exposure to severe childhood sexual (but not physical) abuse is independently associated with an increased risk of psychotic experiences in adulthood (particularly symptoms of abnormal perception) and this association could not be fully accounted for by confounding or time-dynamic covariate factors.Declaration of interestNone.

Abstract
Schizophrenia is associated with brain connection irregularities within and between brain regions. Childhood trauma increases the risk of schizophrenia suggesting that the relationships between childhood trauma and brain connectivity requires further investigation. Here, we examine the relationship between childhood trauma (as measured by the Childhood Trauma Questionnaire) and fractional anisotropy (FA) in 54 minimally treated first-episode schizophrenia (FES) patients and 51 community matched controls. Patients who experienced high levels of trauma had significantly lower FA in the inferior longitudinal fasciculus (ILF), superior longitudinal fasciculus (SLF), and inferior fronto-occipital fasciculus (IFOF) compared with controls who experienced high levels of childhood trauma. A history of childhood sexual abuse in patients was associated with lower FA in the IFOF, ILF, SLF, and forceps major compared with patients without a history of sexual abuse. However, patients who had experienced childhood emotional neglect had higher FA in the right SLF compared to patients with low levels of emotional neglect. Our findings highlight altered cortico-limbic circuitry in FES patients compared with controls and differential effects of childhood emotional neglect and sexual abuse on white matter in patients. Although stress-related white matter (WM) pathways appear to be involved in both schizophrenia and otherwise healthy controls previously exposed to childhood trauma, the pattern of disruption of WM integrity in FES patients appears to be distinct.

Abstract
Patients with an 'At risk mental state' (ARMS) for developing psychosis can be treated successfully with CBT to postpone and prevent the transition to a first psychotic episode. A characteristic of individuals that meet ARMS criteria is that they are still open for multiple explanations for extraordinary experiences. CBT aims to normalize extraordinary experiences with education and to prevent delusional explanations. The treatment is not only effective, but also cost-saving in averting psychosis as well as in reducing disability adjusted life years at 18- and 48-month follow-up. Profiling within the ARMS group results in a personalized treatment. The screening and early treatment for ARMS fulfills all the criteria of the World Health Organization and is ready to be routine screening and treatment in mental health care. At the same time, ARMS patients are complex patients with multi-morbid disorders. Especially childhood trauma is associated to ARMS status, together with co-morbid PTSD, depression, substance abuse and anxiety disorders. Psychotic symptoms appear to be severity markers in other non-psychotic disorders. Preventing psychosis in ARMS patients should be broadened to also address other disorders and aim to reduce chronicity of psychopathology and improve social functioning in general. Several mechanisms play a part in psychopathology in ARMS patients such as stress sensitivity as a result of adverse experiences, dopamine sensitivity that is associated with salience and aggravates several cognitive biases, dissociation mediating between trauma and hallucinations, and low self-esteem and self-stigma. New avenues to treat the complexity of ARMS patients will be proposed.

Abstract
A previous study observed that reported childhood abuse moderated psychotic and emotional reactivity to stress among patients with non-affective psychotic disorder. However, that study used a type of analysis unsuited for skewed data. This study aimed (1) to replicate the study and (2) to examine whether we would obtain similar results using a statistical approach better suited to skewed data. Fifty-nine patients with non-affective psychotic disorder were examined for up to 6 days using an intensive diary method to assess levels of negative affect, psychosis, and daily-life stress. A mixed-linear regression largely replicated earlier findings, but a two-component analysis failed to replicate the moderating effect of reported childhood abuse. These results illustrate the importance of exploring different statistical approaches to skewed data. They may also indicate that stress sensitization does not offer a complete account for the effect of reported childhood abuse on psychotic symptom severity.

Abstract
BACKGROUND Childhood adversity is associated with cognitive impairments in schizophrenia. However, findings to date are inconsistent and little is known about the relationship between social cognition and childhood trauma. We investigated the relationship between childhood abuse and neglect and cognitive function in patients with a first-episode of schizophrenia or schizophreniform disorder (n = 56) and matched healthy controls (n = 52). To the best of our knowledge, this is the first study assessing this relationship in patients and controls exposed to similarly high levels of trauma. METHODS Pearson correlational coefficients were used to assess correlations between Childhood Trauma Questionnaire abuse and neglect scores and cognition. For the MCCB domains displaying significant (p < 0.05) correlations, within group hierarchical linear regression, was done to assess whether abuse and neglect were significant predictors of cognition after controlling for the effect of education. RESULTS Patients and controls reported similarly high levels of abuse and neglect. Cognitive performance was poorer for patients compared with controls for all cognitive domains except working memory and social cognition. After controlling for education, exposure to childhood neglect remained a significant predictor of impairment in social cognition in both patients and controls. Neglect was also a significant predictor of poorer verbal learning in patients and of attention/vigilance in controls. However, childhood abuse did not significantly predict cognitive impairments in either patients or controls. CONCLUSION These findings are cross sectional and do not infer causality. Nonetheless, they indicate that associations between one type of childhood adversity (i.e. neglect) and social cognition are present and are not illness-specific.

Abstract
BACKGROUND The observed link between positive psychotic experiences (PE) and psychosis spectrum disorder (PSD) may be stronger depending on concomitant presence of PE with other dimensions of psychopathology. We examined whether the effect of common risk factors for PSD on PE is additive and whether the impact of risk factors on the occurrence of PE depends on the co-occurrence of other symptom dimensions (affective dysregulation, negative symptoms, and cognitive alteration). METHOD Data from the Netherlands Mental Health Survey and Incidence Study 2 were used. Risk factors included childhood adversity, cannabis use, urbanicity, foreign born, hearing impairment, and family history of affective disorders. Logistic regression models were applied to test (1) the additive effect of risk factors (4 levels) on PE and (2) the moderating effects of symptom dimensions on the association between risk factors (present/absent) and PE, using additive interaction, expressed as the interaction contrast ratio. RESULTS Risk factors were additive: the greater the number of risk factors, the greater the odds of PE. Furthermore, concomitant presence of the other symptom dimensions all increased the impact of risk factors on PE. After controlling for age, sex, and education, only affective dysregulation and negative symptoms remained significant moderators; only affective dysregulation remained a significant moderator if all dimensions were adjusted for each other. CONCLUSIONS Risk factors may not be directly associated with PE but additively give rise to a multidimensional subthreshold state anticipating the multidimensional clinical syndrome. Early motivational and cognitive impairments in the context of PE may be reducible to affective dysregulation.

Abstract
The prevalence of childhood trauma (CT) in schizophrenia spectrum disorders (SSDs) and substance abuse disorders (SUDs) is high. Direct comparisons of CT in these disorders are lacking, and it is not known whether there are differences in self-reported CT in SSDs as compared to SUDs. We aimed to compare the frequency, severity and types of CT in SDDs and SUDs. Patients with SSDs (n = 57) and SUDs (n = 57) were matched for age and gender. Overall levels of CT and CT subtypes were measured retrospectively by the Childhood Trauma Questionnaire Short-Form (CTQ-SF), and grouped into none/low and moderate/severe levels of CT. Group differences in CTQ-SF sum score and subscale scores, as well as differences in the severity of overall CT and CT subtypes were all non-significant. In both groups, 64.9% reported ≥ 1 subtypes of CT above cut-off. Of those who reported CT above the cut-off, 13.5% in the psychosis group reported ≥ 4 subtypes, as compared to 2.7% in the substance abuse group. We did not find statistically significant differences between SSDs and SUDs in terms of exposure to CT frequency or severity, all effect sizes were small (r < 0.15).
