Abstract
OBJECTIVES Child maltreatment (CM) is a major risk factor across the lifespan. While research on CM and its consequences has risen strongly during the last decades, research is mainly focused on the prevalence of types of CM incidents. As valid prevalence rates on timing and chronicity of CM are lacking to date, we aimed to assess the timing of experienced CM by describing the age of onset, duration, and prevalence at each year of age for each CM subtype in a population-based sample. STUDY DESIGN Cross-sectional, observational study in a representative sample. METHODS Using different sampling steps including a random route procedure, a probability sample of the German population above the age of 16, encompassing 2514 persons (50.6% female, mean age: 50.08 years) was generated. Participants were asked about sociodemographic information in a face-to-face interview, CM was assessed using the ICAST-R questionnaire. RESULTS The earliest mean age of onset was seen in neglect with 8.07 (±3.07) years for boys and 7.90 (±2.96) years for girls, while the mean age of onset for sexual abuse was in adolescence with 13.65 (±3.86) years for boys and 13.91(±3.17) years for girls. The overall duration of CM was lowest for sexual abuse with 2.12 (±2.01) years for boys and 2.35 (±1.73) years for girls, the highest duration was seen for emotional abuse with 4.00 (±3.54) years for boys and 4.21 (±3.77) years for girls. CONCLUSIONS Our novel results provide important epidemiological information for prevention efforts.

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.

Psychotic experiences and dissociation in adolescents: Within-person analysis in the Tokyo teen cohort. Schizophr Res 2024; 270:416-422. [PMID: 38991417 DOI: 10.1016/j.schres.2024.07.003] [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: 12/10/2023] [Revised: 07/01/2024] [Accepted: 07/03/2024] [Indexed: 07/13/2024]
Abstract
Although many cross-sectional studies showed that psychotic experiences (PEs) and dissociation were closely related, the longitudinal association between them remains unknown. Therefore, the aim of the current study was to examine the longitudinal association of these two symptoms throughout adolescence, under the hypothesis that these two symptoms are bidirectionally associated. Data were obtained from a population-based cohort, the Tokyo Teen Cohort study (TTC; N = 3171). PEs and dissociation were assessed at 10, 12, 14, and 16 years of age. PEs were assessed using a total score from five-item self-report questionnaires derived from the Diagnostic Interview Schedule for Children (DISC-C). Dissociation was assessed using subscale scores of the Child Behavior Checklist (CBCL) completed by primary caregivers. We examined the longitudinal relationship between PEs and dissociation using the random intercept cross-lagged panel model (RI-CLPM). The within-person component of the RI-CLPM revealed no significant cross-lagged effect of dissociation on PEs at any time point. On the other hand, there was a significant (p < 0.05) association between PEs at age 14 and dissociation at age 16 (β = 0.106, 95 % CI 0.047-0.165). The between-person component revealed a significant time-invariant relationship between the two symptoms (β = 0.324, 95 % CI 0.239-0.410). The longitudinal relationship between PEs and dissociation was limited at the within-person level, whereas the between-person correlation was significant. The only significant longitudinal pathway was from PEs to dissociation, suggesting that PEs may be a predictor of dissociation in mid-adolescence.

Differential Risk: Gender and Racial Differences in the Relationship between Trauma, Discrimination, and Schizotypy. Behav Sci (Basel) 2024; 14:363.

Abstract
Traumatic experiences are associated with increased experiences of positive schizotypy. This may be especially important for People of Color, who experience higher rates of trauma and racial discrimination. No study to date has examined how racial disparities in traumatic experiences may impact schizotypy. Furthermore, of the studies that have examined the relationship between trauma and schizotypy, none have examined racial discrimination as a potential moderator. The present study examined if racial discrimination moderates the relationship between trauma and multidimensional (positive, negative, and disorganized) schizotypy. In a sample of 770 college students, we conducted chi-squared analyses, analyses of variance, and stepwise regressions. We found that Black students experienced significantly higher racial discrimination and trauma than Latinx and Asian students. Furthermore, Black and Latinx students experienced significantly more multidimensional schizotypy items than Asian students. Trauma and racial discrimination explained 8 to 23% of the variance in each dimension of schizotypy. Racial discrimination did not moderate the relationships between trauma and multidimensional schizotypy. Our findings suggest that we need to examine risk factors that may prevent recovery from psychotic disorders. Additionally, disorganized schizotypy showed the most robust associations and may be a critical site of intervention.

Abstract
Exposure to trauma during childhood is a non-specific risk factor for psychiatric disorders, including eating disorders (EDs), over the life course. Moreover, an association between stressful life events and the onset/maintenance of EDs has been documented. Therefore, the hypothalamus-pituitary-adrenal (HPA) axis, namely the main component of the endogenous stress response system, has been proposed to be implicated in the pathophysiology of EDs. In this narrative review the current knowledge concerning the effects of early trauma exposure on the HPA axis activity and their putative role in the pathophysiology of EDs will be illustrated. Research findings corroborate the idea that childhood trauma exposure has long-lasting dysregulating effects on the activity of the HPA axis, which may contribute to the biological background of the early trauma-related risk for the development of EDs across the life span. Moreover, literature data support the existence of a "maltreated ecophenotype" in EDs characterized by specific clinic and neuroendocrine features, which may have important implications in treatment programming for such a type of patients.

Abstract
Background: Although child maltreatment (CM) has been linked to health problems and poor psychosocial functioning, not all individuals exposed to CM develop or experience negative consequences later in life. This suggests that some individuals show resilience after being exposed to CM. However, conclusions have been limited by inconsistent findings across different CM subtypes and resilience domains.Objective: To develop a protocol for conducting a systematic review and meta-analysis to quantify associations between CM (overall and its subtypes) and resilience (global and its multiple domains) in adulthood, and to examine moderators and mediators of these associations.Method: PubMed, PsycINFO, Embase, Scopus, and Web of Science will be searched to identify relevant studies on the association between CM (exposure) and resilience (outcome) in adults (≥ 18 years). Data will be screened and extracted by at least two independent reviewers. The methodological quality of the included studies will be independently assessed with a modified version of the Newcastle-Ottawa Scale (NOS). If deemed viable, a meta-analysis will be conducted using a random effects model. Heterogeneity of evidence will be estimated with the I2 statistic, and publication bias will be assessed. The effects of potential moderators (e.g. timing and severity of CM, age, sex, family cohesion, socio-economic status, country/region) will be analysed using meta-regression and subgroup analyses, and meta-analytical structural equation modelling will be employed to synthesise indirect mediation effects. Candidate moderators and mediators (e.g. genetic factors, brain functioning, attachment style, personality traits, physical activity, and social support) will be also examined qualitatively.Conclusions: This protocol will facilitate a systematic review and meta-analysis that has the potential to enhance our knowledge about the association between CM exposure in early life and resilience in adulthood. Understanding associations and underlying mechanisms between CM and resilience is potentially important in informing prevention and interventions to sustain health and improve outcomes among adults with a history of CM.PROSPERO registration: CRD42023394120.

Abstract
Stress is viewed as a state of real or perceived threat to homeostasis, the management of which involves the endocrine, nervous, and immune systems. These systems work independently and interactively as part of the stress response. The scientific stress literature, which spans both animal and human studies, contains heterogeneous findings about the effects of stress on the brain and the body. This review seeks to summarise and integrate literature on the relationships between these systems, examining particularly the roles of physiological and psychosocial stress, the stress hormone cortisol, as controlled by the hypothalamic-pituitary-adrenal (HPA) axis, and the effects of stress on cognitive functioning. Health conditions related to impaired HPA axis functioning and their associated neuropsychiatric symptoms will also be considered. Lastly, this review will provide suggestions of clinical applicability for endocrinologists who are uniquely placed to measure outcomes related to endocrine, nervous and immune system functioning and identify areas of intervention.

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 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.

Lancet Psychiatry 2022; 9:978-991.

Abstract
Variation in the mental health of people who have experienced childhood maltreatment is substantial. One hypothesis is that this variation is attributable, in part, to the timing of maltreatment-specifically, whether maltreatment occurs during sensitive periods in development when the brain is maximally sensitive to particular types of environmental input. To determine whether there is scientific consensus around when periods of peak sensitivity occur, we did a systematic review of human observational studies. Although 89 (75%) of the 118 unique cross-sectional or longitudinal cohort studies we identified reported timing effects, no consistent sensitive periods were identified for any of the most studied outcomes. Thus, observational research on childhood maltreatment has yet to converge on a single period (or set of periods) of increased vulnerability. We identified study characteristics that might contribute to these between-study differences and used observations from our Review to suggest a comprehensive set of recommendations for future research.

Abstract
BACKGROUND Psychosis is more prevalent among Black individuals compared with White individuals. However, it is unknown whether this disparity exists among college populations in the United States, and if so, what factors contribute to the disparity. METHODS We analyzed data from Black and White young adult students using the Health Minds Study (2020-2021), which is a survey administered at 140 colleges in the U.S. Using mediation analysis, we examined the extent to which the relation between race and psychotic experiences was mediated by socioeconomic factors (past and current financial distress, food insecurity, parental education) and discrimination. RESULTS Approximately 38 % of Black students and 30 % of White students reported lifetime psychotic experiences. Including all socioeconomic factors together in the same model accounted for just over half (50.2 %) the association between race and psychotic experiences. We then conducted additional analyses examining discrimination, all the socioeconomic factors plus discrimination accounted for 81.5 % of the association between race and psychotic experiences. When disentangling the mediators, food insecurity and discrimination accounted for the largest percentages of the association. The effects of past financial distress and parental education were modified by race. CONCLUSION Black college students were more likely to report lifetime psychotic experiences than their White counterparts. Moreover, socioeconomic factors and discrimination made significant contributions to this racial difference.

Abstract
Robust evidence exists for the link between dissociation and psychotic positive symptoms. The extent to which various dissociative phenomena may contribute to this relationship is still unknown. This study aimed to investigate the association between different dissociative phenomena and psychotic experiences. For this purpose, we analyzed data from 118 consecutively admitted patients of an acute care unit for trauma-related disorders who completed the Childhood Trauma Questionnaire, the German version of the Dissociative Experiences Scale and the Symptom Check-List-90-Revised. Stepwise regression analyses revealed that derealization/depersonalization in combination with amnesia accounted for 44.5% of the variance of the psychoticism subscale of the Symptom Check-List-90-Revised. Absorption in combination with emotional abuse accounted for 24.9% of the variance of the paranoid ideation subscale of the Symptom Check-List-90-Revised. The results reveal that pathological and non-pathological types of dissociation that alter the perception of reality or memory procession may contribute to the development of psychotic experiences.

Abstract
Previous studies have shown that neurodevelopmental characteristics of adverse childhood experiences (ACEs), such as their accumulation and minimal age at exposure, might moderate their impact on clinical expression of psychosis. However, it remains unknown as to whether specific neurodevelopmental characteristics of ACEs are associated with biological alterations observed in psychosis. In this study, we tested the hypothesis that younger minimal age at exposure as well as greater accumulation and severity of ACEs are associated with systemic biological dysregulations captured by the allostatic load (AL) index in patients with psychosis. The present study included 65 inpatients with psychotic disorders and 56 healthy controls (HCs). A total of 15 biomarkers were used to measure the AL index. Individuals with psychosis had significantly higher AL index as well as they reported greater accumulation and severity of ACEs compared to HCs. After adjustment for age, sex, the number of education years and the dosage of antipsychotics, greater accumulation of ACEs and younger minimal age at exposure were significantly associated with higher AL index in patients with psychosis. None of neurodevelopmental characteristics of ACEs was associated with the AL index in HCs. Our findings indicate that greater accumulation of ACEs and younger minimal age at exposure are related to biological dysregulations captured by the AL index in patients with psychosis. Future studies investigating the role of ACEs in the pathophysiology of psychosis need to consider their neurodevelopmental characteristics. It is also important to further explore timing of exposure to indicate critical developmental periods related to psychosis risk and better inform potential interventions.

Abstract
There are several effective self-report instruments used by Chinese researchers to retrospectively assess exposure to childhood maltreatment. However, these measures do not assess the timing of exposure, restricting efforts to identify periods of development when childhood maltreatment maximally increases vulnerability to psychopathology and health outcomes. In the current study we created a Chinese version of the Maltreatment and Abuse Chronology of Exposure (MACE) scale, which assesses multiplicity (number of types of maltreatment experienced) and severity of maltreatment as well as when it occurred during childhood and adolescence. Rasch modeling was used for scale development in a sample of 812 undergraduate students. Item reduction analysis of the original 75 items produced a 58-item Chinese version with ten subdimensions. The new scale showed good three-week test-retest reliability, and good convergent validity with the Childhood Trauma Questionnaire (CTQ) and the revised Adverse Childhood Experiences Questionnaire (ACEQ-R). Variance decomposition analyses found that compared to the CTQ and ACE, the MACE Severity and Multiplicity scores explained higher variance in self-reported depression and anxiety symptom ratings on the Depression Anxiety Stress Scales (DASS). The results of the present study confirmed that the Chinese version of the MACE has sound psychometric properties in the Chinese cultural context. This new instrument will be a valuable tool for Chinese researchers, psychiatrists and psychologists to ascertain the type and timing of exposure to maltreatment.

Abstract
Adolescents are at risk for becoming victims or perpetrators for a variety of forms of dating violence, including cyber violence, physical violence, psychological abuse, and sexual abuse. Interestingly, a robust predictor of dating violence is adverse experiences during childhood; however, factors that could mitigate the risk of dating violence for those exposed to adversity have seldom been examined. Using the cumulative stress hypothesis as a lens, the current study examined severity of adverse experiences as a predictor of dating violence within a sample at risk for both victimization and perpetration of dating violence: An adolescent (12-17 years old; N = 137) sample who were receiving inpatient psychiatric treatment. First, the current study aimed to replicate previous findings to determine whether adversity predicted dating violence and whether this varied by gender. Then, the current study examined one factor that could mitigate the relation between adversity and dating violence-parental emotion validation. High rates of maternal emotion validation resulted in no relation between adversity and dating violence perpetration and victimization; however, the relation was present at average and low levels of maternal emotion validation. Next, by adding gender as an additional moderator to the model, we found that high rates of paternal emotion validation extinguished the relation between adversity and dating violence perpetration, but only for adolescent boys. This pattern was not found for maternal emotion validation. Interestingly, the relation between adversity and dating violence victimization did not vary as a function of maternal or paternal validation of emotion for either child gender. These findings are discussed in terms of their meaning within this sample, possible future directions, and their implications for the prevention of dating violence.

Abstract
Childhood maltreatment represents a form of trauma capable of altering fundamental neurobiological properties and negatively impacting neurodevelopmental processes. An outcome of childhood maltreatment is the emergence of psychopathology, which might become evident during childhood or adolescence, but might also project into adulthood. In this Review, we propose a biobehavioural framework in which childhood maltreatment and the associated aberrant neurobiological mechanisms and behavioural processes additionally lead to the onset of altered pain processing and, ultimately, the existence of pain syndromes. Considering that subpopulations of maltreated children show preserved function and minimal psychiatric or pain symptoms, compensatory mechanisms-perhaps instilled by robust psychosocial support systems-are also discussed. We present validated tools and experimental methods that could facilitate better comprehension of the interactions between childhood maltreatment, psychopathology, and pain. Such tools and approaches can in parallel be implemented to monitor abnormal pain-related processes and potentially guide early intervention strategies in cases of childhood maltreatment.

Abstract
Corpus callosum (CC) abnormalities have been observed in several psychiatric disorders. Maltreatment has also been associated with marked differences in CC anatomy and microstructure, though rarely controlled for in psychiatric neuroimaging studies. The aim of this study was to identify type and timing of maltreatment associated with alterations in CC microstructure and to ascertain if they differ by sex. T1 and diffusion-weighted MRIs were obtained from 345 (135 M/210 F) healthy 18-25-year-olds. The Maltreatment and Abuse Chronology of Exposure scale provided retrospective data on exposure to ten types of maltreatment across each year of childhood. AI predictive analytics were used to identify the most significant type and time risk factors. The most striking maltreatment-associated alterations in males were in axial diffusivity and were most specifically associated with exposure to emotional abuse or neglect during segment-specific sensitive periods. In contrast, maltreatment was associated with marked alteration in radial diffusivity and fractional anisotropy in females and was most specifically associated with early physical neglect during one common sensitive period involving all segments except the splenium. Overall sex differences, controlling for maltreatment, brain size, and sociodemographic factors were limited to the genu with greater fractional anisotropy in males and radial diffusivity in females. These findings suggest that maltreatment may target myelinization in females and axonal development in males and that these sex differences need to be taken into account in studies seeking to delineate the contribution of CC abnormalities and interhemispheric communication to psychiatric disorders.

Abstract
Abstract
Background
Adverse childhood experiences (ACEs) and substance use disorder (SUD) are well-known risk factors for psychosis and dramatically affect schizophrenia. In this research, we aimed to measure the prevalence of adverse childhood experiences and substance use disorder in patients with schizophrenia and assess the effect of ACEs on the clinical presentation and overall functioning and the association between them and SUD in patients with schizophrenia. A cross-sectional study included a random sample of 165 schizophrenic patients who were examined by doing drug screen in urine, structured questionnaire to collect Socioeconomic characteristics, history of schizophrenia, structured clinical interview for Diagnostic and Statistical Manual of Mental Disorders-fifth edition, Positive and Negative Syndrome Scale (PANSS), Adverse Childhood Experiences International Questionnaire (ACE-IQ), World Health Organization Disability Assessment Schedule 2.0, compliance rating scale, addiction severity index fifth edition (ASI) for individuals with positive urine drug screen.
Results
Only 14.4% of the studied patients had no adverse childhood experiences. The prevalence of positive substance abuse screening was 18.2%. There were statistically significant negative correlations between total ACE score and educational level, socioeconomic level, and the onset of schizophrenia. On the other hand, statistically significant positive correlations were found between the total ACE score and PANSS score and ASI score. The first most frequent ACE was significantly associated with female gender, lower education levels, low and middle socioeconomic classes, lifetime substance use, smokers, and positive drug screening. Emotional neglect and contact sexual abuse were significantly associated with positive drug screening. At the same time, Physical abuse was significantly associated with both lifetime substance use and positive drug screening.
Conclusion
The current study’s findings indicate that childhood adverse experiences and substance abuse are prevalent problems in patients with schizophrenia. Given that there is an association between both issues, they may affect the symptomatology of the disorder, the prognosis, and the therapeutic plan. It is advised that a greater emphasis on and identification of childhood trauma and drug use disorder may be a necessary step in assessing patients with schizophrenia.

Abstract
Early life adversity (ELA) increases the risk of developing neuropsychiatric illnesses such as anxiety disorders. However, the mechanisms connecting these negative early life experiences to illness later in life remain unclear. In rodents, plasticity mechanisms, specifically adult neurogenesis in the ventral hippocampus, have been shown to be altered by ELA and important for buffering against detrimental stress-induced outcomes. The current study sought to explore whether adult neurogenesis contributes to ELA-induced changes in avoidance behavior. Using the GFAP-TK transgenic model, which allows for the inhibition of adult neurogenesis, and CD1 littermate controls, we subjected mice to an ELA paradigm of maternal separation and early weaning (MSEW) or control rearing. We found that mice with intact adult neurogenesis showed no behavioral changes in response to MSEW. After reducing adult neurogenesis, however, male mice previously subjected to MSEW had an unexpected decrease in avoidance behavior. This finding was not observed in female mice, suggesting that a sex difference exists in the role of adult-born neurons in buffering against ELA-induced changes in behavior. Taken together with the existing literature on ELA and avoidance behavior, this work suggests that strain differences exist in susceptibility to ELA and that adult-born neurons may play a role in regulating adaptive behavior.

Abstract
BACKGROUND Adverse childhood experiences (ACEs) tend to cluster together in daily life, and most studies focus on the level of depression at certain points, but the dynamic process of depression is often neglected. Thus, research is urgently needed to explore the relationship between ACEs pattern and trajectory of depressive symptom levels at multiple time points in order to provides early targeted interventions to those who are most at risk. OBJECTIVE We aimed to explore patterns of ACEs, including types and timing, associated with depression trajectories in college students. METHODS A school-based health survey was used to collect data as part of a longitudinal study in two medical college in Anhui province, China. Questionnaires were issued to 3,662 participants aged 17-22 and recorded details of ACEs (types and timing) and depression. Latent class analysis (LCA) was used to identify "patterns" of ACEs type and timing. Depressive symptom trajectories employed latent class growth analysis (LCGA). Multiple logistic regressions were employed to evaluate the relationships between ACEs patterns and depressive symptom trajectories. RESULTS We identified five ACEs patterns: "High neglect/emotional abuse/community violence," "High neglect/emotional abuse," "High neglect/family dysfunction," "High neglect," "Low ACEs." We traced three depression trajectories: "High depressive symptom" "Moderate depressive symptom," "Low depressive symptom." "High neglect/emotional abuse/community violence," "High neglect/emotional abuse" and "High neglect/family dysfunction" demonstrated a high risk for "High depressive symptom" and "Moderate depressive symptom." "High neglect" showed a high risk for "Moderate depressive symptom" but not for "High depressive symptom" (P < 0.05). CONCLUSIONS The findings address the need for a comprehensive consideration of exposure to childhood adversity associated with the risk of depression in young adults through identifying more problematic ACEs patterns amongst exposed children.

Abstract
Dissociation is problematic in its own right for patients with psychosis but may also contribute to the occurrence of psychotic experiences. We therefore set out to estimate in a large cohort of patients with psychosis the prevalence of dissociative experiences, and assess using network models the relationships between dissociation, its potential maintenance mechanisms, and mental health symptoms. 902 patients with non-affective psychosis attending UK mental health services participated. Both an undirected model and a partially directed network model were estimated to identify potential relationships between 'felt sense of anomaly' dissociative experiences, paranoia, hallucinations, psychological wellbeing, sleep, and six potential maintenance mechanisms (affect intolerance, perseverative thinking, general self-efficacy, alexithymia, cognitive appraisals, and cognitive-behavioural responses to dissociation). 617 patients (65.4%) had experienced at least one dissociative symptom regularly over the past fortnight, with the average number experienced being 8.9 (SD = 8.0). Dissociation had direct relationships with paranoia, hallucinations, low psychological wellbeing, cognitive appraisals, cognitive-behavioural responses to dissociation, perseverative thinking, and low alexithymia. Dissociation was a probable cause of hallucinations (94.21% of 50,000 sampled directed acyclic graphs), with a trend towards also being a cause of paranoia (86.25% of 50,000 sampled directed acyclic graphs). Approximately two-thirds of patients with psychosis experience regular dissociative experiences. Dissociation is associated with low psychological wellbeing, and it is likely to have a direct causal influence on psychotic symptoms. Catastrophic cognitive appraisals, cognitive-behavioural responses to dissociation, factors related to affect sensitivity, and perseverative thinking may contribute to the occurrence of dissociation.

Abstract
Purpose Several studies have shown that individuals with schizophrenia-spectrum disorders (SSD) employ ineffective coping styles. However, it remains unknown whether a history of adverse childhood experiences (AC Es), associated with a risk of SSD, contributes to these observations. Therefore, in this study, we aimed to investigate whether exposure to ACEs is associated with coping styles in subjects with SSD. Patients and Methods We recruited 127 inpatients with SSD and 56 healthy controls. Coping styles and ACEs were recorded using self-reports. Results Individuals with SSD had significantly higher use of using avoidance coping. A history of parental antipathy, physical and sexual abuse was significantly more frequent in subjects with SSD compared to controls. Subjects with SSD had significantly higher multiplicity and severity of ACEs. Individuals with SSD and a history of parental loss had significantly higher use of avoidance coping compared to controls with and without a history of parental loss. Other characteristics of ACEs (age at first exposure, severity and multiplicity) were not associated with using specific coping strategies. Conclusion These findings imply that higher use of using avoidance coping by individuals with SSD might be related to a history of parental loss.

Abstract
AIMS Most research exploring the link between traumatic events and psychotic experiences has focused on either Australia, Europe or North America. In this study, we expand the existing knowledge to Thailand and investigate the impact of the type and the number of traumatic events on psychotic experiences in Thailand. METHODS We used data from the nationally representative 2013 Thai National Mental Health Survey (TNMHS), including questions on traumatic events and psychotic experiences. We regressed the lifetime experience of hallucinations or delusions against the following independent variables: the experience of any traumatic event during lifetime (dichotomous; hypothesis 1); the experience of either no traumatic event, one interpersonal, one unintentional or both interpersonal and unintentional traumatic events (categorical; hypothesis 2) and the number of traumatic events experienced during lifetime (categorical; hypothesis 3). We adjusted the regression models for sociodemographic indicators and psychiatric disorders, and considered survey weights. RESULTS About 6% (95% confidence interval: 4.9-7.0) of the respondents stated that they had either hallucinatory or delusional experiences during their lifetime. The risk of reporting such experiences was more than doubled as high among respondents who had experienced at least one traumatic event during their lifetime than among those who had not yet experienced one, with higher risks for interpersonal or multiple traumatic events. Our results further indicated an increase in the risk of psychotic experiences as the number of traumatic events increased, with up to an eight-fold higher risk for people exposed to five or more traumatic events in their lifetime, compared to those with no traumatic events. CONCLUSIONS Individuals reporting interpersonal or multiple traumatic events face much higher risk of psychotic experiences. Effective and widely accessible secondary prevention programmes for people having experienced interpersonal or multiple traumatic events constitute a key intervention option.

Abstract
BACKGROUND There is considerable evidence of dysconnectivity within the default-mode network (DMN) in schizophrenia, as measured during resting-state functional MRI (rs-fMRI). History of childhood trauma (CT) is observed at a higher frequency in schizophrenia than in the general population, but its relationship to DMN functional connectivity has yet to be investigated. METHODS CT history and rs-fMRI data were collected in 65 individuals with schizophrenia and 132 healthy controls. Seed-based functional connectivity between each of 4 a priori defined seeds of the DMN (medial prefrontal cortex, right and left lateral parietal lobes, and the posterior cingulate cortex) and all other voxels of the brain were compared across groups. Effects of CT on functional connectivity were examined using multiple regression analyses. Where significant associations were observed, regression analyses were further used to determine whether variance in behavioral measures of Theory of Mind (ToM), previously associated with DMN recruitment, were explained by these associations. RESULTS Seed-based analyses revealed evidence of widespread reductions in functional connectivity in patients vs controls, including between the left/right parietal lobe (LP) and multiple other regions, including the parietal operculum bilaterally. Across all subjects, increased CT scores were associated with reduced prefrontal-parietal connectivity and, in patients, with increased prefrontal-cerebellar connectivity also. These CT-associated differences in DMN connectivity also predicted variation in behavioral measures of ToM. CONCLUSIONS These findings suggest that CT history is associated with variation in DMN connectivity during rs-fMRI in patients with schizophrenia and healthy participants, which may partly mediate associations observed between early life adversity and cognitive performance.

Abstract
AIM Childhood adversities have been linked to an increased risk for psychosis. However, as yet, there has been comparatively little research on the effects of neglect. This study examined the association between childhood physical neglect and psychotic experiences (PEs) in a general population sample. METHODS Data were analysed from 2308 individuals collected during the National Comorbidity Survey Replication (NCS-R). Information on lifetime PEs was collected with the WHO-CIDI Psychosis Screen. Respondents also reported on five forms of childhood neglect (went hungry, went without necessities, went unsupervised, lacked medical care, chores too difficult/dangerous). Multivariable logistic regression analysis was used to examine associations. RESULTS In models adjusted for sociodemographic and psychiatric disorder variables, aggregated physical neglect scores (continuous/dichotomized) were associated with significantly increased odds for any lifetime PEs. All individual forms of neglect except went without necessities (odds ratio [OR]: 1.21, 95% confidence interval [CI]: 0.98-1.50) were significantly associated with PEs with ORs ranging from 1.28 (95% CI: 1.08-1.51, went unsupervised) to 1.53 (95% CI: 1.19-1.97, went without medical care). In models that were further adjusted for co-occurring forms of neglect and childhood physical abuse, doing chores that were too difficult/dangerous continued to be associated with significantly increased odds for PEs (OR: 1.29, 95% CI: 1.03-1.61). CONCLUSIONS Childhood physical neglect is associated with significantly increased odds for PEs in the general population. Screening for childhood adversities and PEs among potential patients may be important for the early detection of individuals at high risk for psychosis, as well as for formulating comprehensive and effective treatment plans.

Abstract
Experiencing psychological trauma during childhood and/or adolescence is associated with an increased risk of psychosis in adulthood. However, we lack a clear knowledge of how developmental trauma induces vulnerability to psychotic symptoms. Understanding the psychological processes involved in this association is crucial to the development of preventive interventions and improved treatments. We sought to systematically review the literature and combine findings using meta-analytic techniques to establish the potential roles of psychological processes in the associations between developmental trauma and specific psychotic experiences (i.e., hallucinations, delusions and paranoia). Twenty-two studies met our inclusion criteria. We found mediating roles of dissociation, emotional dysregulation and post-traumatic stress disorder (PTSD) symptoms (avoidance, numbing and hyperarousal) between developmental trauma and hallucinations. There was also evidence of a mediating role of negative schemata, i.e. mental constructs of meanings, between developmental trauma and delusions as well as paranoia. Many studies to date have been of poor quality, and the field is limited by mostly cross-sectional research. Our findings suggest that there may be distinct psy-chological pathways from developmental trauma to psychotic phenomena in adulthood. Clinicians should carefully ask people with psychosis about their history of developmental trauma, and screen patients with such a history for dissociation, emotional dysregulation and PTSD symptoms. Well conducted research with prospective designs, including neurocognitive assessment, is required in order to fully understand the biopsychosocial mechanisms underlying the association between developmental trauma and psychosis.

Abstract
Cumulative lifetime trauma has a profound impact on the development of schizophrenia spectrum disorders. However, few studies have determined participants' most distressing (i.e., "worst") life event in childhood or adulthood or examined whether this event contributes to poorer clinical outcomes. The present study aimed to (a) determine the associations between the worst life event and demographic/clinical variables and (b) examine the associations between the worst life event and psychiatric symptoms (i.e., positive, negative, depressive, and anxiety symptoms). Participants (N = 150) were outpatients newly diagnosed with schizophrenia spectrum disorders who were assessed for lifetime trauma exposure, positive and negative symptoms of schizophrenia, and symptoms of depression and anxiety. Multinomial logistic regression analysis was conducted to examine the associations between demographic and clinical variables and worst life events (none, childhood, or adulthood). Multiple linear regression analyses were performed to examine the associations between worst life events and psychiatric symptoms. More participants reported that their worst life event occurred during adulthood (31.1%) than childhood (21.3%). Adulthood trauma was associated with male gender, older age, non-Chinese ethnicity, and psychiatric comorbidities; childhood trauma was associated with a family history of depression/anxiety. Adulthood trauma was significantly associated with more severe positive psychotic symptoms, f2 = 0.19, whereas childhood and adulthood trauma exposure were both significantly associated with more severe depressive and anxiety symptoms, f2 s = 0.19 and 0.25, respectively. Our findings underscore the importance of conducting assessments for worst life events and the associated risk factors to develop meaningful formulations and appropriate trauma-focused treatment plans.

Abstract
Suicide is a cause of early mortality in nearly 5% of patients with schizophrenia, and 25-50% of patients with schizophrenia attempt suicide in their lifetime. Evidence points to numerous individual, clinical, social, and psychological risk factors for suicide in patients with schizophrenia. Although recognizing suicidal risk factors in schizophrenia is extremely important in suicidal risk assessment, we have recently witnessed a change in suicide risk management that shifts the focus from suicide risk assessment to suicide risk formulation. Suicide risk formulation is dependent on the data gathered in the suicide risk assessment and assigns a level of suicide risk that is indispensable for the choice of treatment and the management of patients with a high suicidal risk. In this article, we extend the suicide risk formulation model to patients with schizophrenia. Suicide risk formulation results from four different areas that help clinicians collect as much information as possible for the management of suicidal risk. The four distinct judgments comprise risk status (the risk relating to the specific group to which the patient belongs), risk state (the risk for the person compared with his baseline or another reference point in the course of his life), available resources (on whom the person can count during a crisis) and foreseeable events (which can exacerbate the crisis). In schizophrenia, the suicide risk formulation model allows the clinician to evaluate in depth the clinical context of the patient, the patient's own history and patient-specific opportunities for better choosing and applying suicide prevention strategies.

Abstract
There is growing evidence for a main role of environment in the occurrence of mental disorders such as a psychosocial risk factor, for example, childhood trauma, discrimination linked to minority status, or migrant status. One hypothesis is that social adversity factors influence the risk of schizophrenia through a common pathway: social defeat which could be defined as the impotence of a subject in the face of a situation of social adversity, with a consequential experience of devaluation on the social scale. This review proposes to explain the animal model of social defeat which provides an overview of the neurobiological consequences of chronic stress. Then, we expose this topic in humans, the assessment methods, and its psychopathological field. Finally, we expose epidemiologic and neurobiological evidences, in particular the dopaminergic sensitization process, which provide evidence of a significant role of social defeat in schizophrenia risk due to exposure to psychosocial factors. This etiopathogenic hypothesis has several issues. First, a common pathway to several environmental risk factors could allow an ethiopathogenic model more parcimonious for schizophrenia. It could also allow the assessment and prevention of adversity factors involved in social defeat so as to finally improve the outcome of subjects who have an individual risk for schizophrenia.

The history of multiple adverse childhood experiences in patients with schizophrenia is associated with more severe symptomatology and suicidal behavior with gender-specific characteristics. Psychiatry Res 2020; 293:113411.

Abstract
The current study aims to compare the prevalence of adverse childhood experiences (ACEs) between patients with schizophrenia and non-psychiatric control group, and to analyze the association of having suffered multiple ACEs with clinical symptoms of schizophrenia and suicidal behavior. A multicenter, cross-sectional study was conducted across three facilities in Buenos Aires, Argentina. One-hundred patients with schizophrenia and 50 healthy subjects were assessed with the Adverse Childhood Experiences questionnaire (ACE-Q), the Positive and Negative Syndrome Scale (PANSS), and the Columbia-Suicide Severity Rating Scale (C-SSRS). We observed that the prevalence of at least one ACE in schizophrenic patients was almost double in comparison with the non-psychiatric control group. Multiple ACEs were associated with persistent auditory hallucinations and lower negative symptoms in both sexes. Higher frequency of death ideation and a higher number of suicide attempts were reported among women. The strength of this study is the possibility of comparing the presence of ACEs between schizophrenic patients and non-psychiatric control using the same questionnaire in an under-reported sample of low socio-economic patients assisted in public hospitals. A limitation is that the history of ACEs relied on the retrospective assessment of childhood experiences, and adults could over-report ACEs because of recall bias.

Abstract
OBJECTIVES Childhood maltreatment has been associated to an increased risk of developing bipolar disorder (BD). A role of the hypothalamus-pituitary-adrenal (HPA) axis in mediating trauma-related risk for adult psychopathology has been suggested but scarcely investigated in BD. Therefore, we explored the impact of childhood maltreatment on clinical features of BD and on the activity of the HPA axis. METHODS One hundred and six patients participated in the study. On the basis of their history of childhood trauma, as assessed by the Childhood Trauma Questionnaire (CTQ), they were divided into a group with a history of childhood maltreatment (CM+) and a group without (CM-). Twenty-nine participants (16 with a history of childhood trauma and 13 without) underwent the cortisol awakening response (CAR) test. RESULTS Sixty-two patients had a history of childhood maltreatment and 44 had not. Maltreatment was significantly more frequent in females than males. CM+ patients showed a significant higher body mass index, a significant higher number of suicide attempts, and more severe mania symptoms than CM- ones. Logistic regression indicated a significant association between lifetime suicide attempts and any type of childhood maltreatment and between emotional abuse and the presence of psychotic symptoms or mixed mood episodes. CM+ individuals with BD exhibited a significantly reduced CAR with respect to CM- ones. DISCUSSION Our results add to literature findings showing a worse clinical course in BD patients with a history of childhood maltreatments and show for the first time that childhood trauma exposure is associated to an impaired CAR in adults with BD.

Abstract
Schizophrenia is associated with significant health, social, occupational, and economic burdens, including increased mortality. Despite extensive and robust research on the treatment of individuals with schizophrenia, many individuals with the illness do not currently receive evidence-based pharmacological and nonpharmacological treatments. The American Psychiatric Association Practice Guideline for the Treatment of Patients With Schizophrenia, Third Edition, aims to enhance knowledge and increase the appropriate use of interventions for schizophrenia, thereby improving the quality of care and treatment outcomes. To this end, this evidence-based Performance in Practice tool can facilitate the implementation of a systematic approach to practice improvement for the care of individuals with schizophrenia. This practice assessment activity can also be used in partial fulfillment of Continuing Medical Education and Maintenance of Certification, part IV, requirements, which can also satisfy requirements for the Centers for Medicare & Medicaid Services Merit-based Incentive Payment System program.

Abstract
Various psychological and biological pathways have been proposed as mediators between childhood adversity (CA) and psychosis. A systematic review of the evidence in this domain is needed. Our aim is to systematically review the evidence on psychological and biological mediators between CA and psychosis across the psychosis spectrum. This review followed PRISMA guidelines. Articles published between 1979 and July 2019 were identified through a literature search in OVID (PsychINFO, Medline and Embase) and Cochrane Libraries. The evidence by each analysis and each study is presented by group of mediator categories found. The percentage of total effect mediated was calculated. Forty-eight studies were included, 21 in clinical samples and 27 in the general population (GP) with a total of 82 352 subjects from GP and 3189 from clinical studies. The quality of studies was judged as 'fair'. Our results showed (i) solid evidence of mediation between CA and psychosis by negative cognitive schemas about the self, the world and others (NS); by dissociation and other post-traumatic stress disorder symptoms; and through an affective pathway in GP but not in subjects with disorder; (iii) lack of studies exploring biological mediators. We found evidence suggesting that various overlapping and not competing pathways involving post-traumatic and mood symptoms, as well as negative cognitions contribute partially to the link between CA and psychosis. Experiences of CA, along with relevant mediators should be routinely assessed in patients with psychosis. Evidence testing efficacy of interventions targeting such mediators through cognitive behavioural approaches and/or pharmacological means is needed in future.

Abstract
Childhood trauma (CT) is a risk factor for schizophrenia spectrum disorders (SSDs), and cognitive impairment is a core feature and a vulnerability marker of SSDs. Studies of the relationship between CT and cognitive impairment in SSDs are inconclusive. In addition, few studies have examined differential effects of CT subtypes, e.g. physical, sexual or emotional abuse/neglect, on cognitive functioning. The present study therefore aimed to examine the effects of CT and CT subtypes on cognitive impairment in SSD. Participants (n = 78) with SSDs completed a comprehensive neuropsychological test battery and the Childhood Trauma Questionnaire Short-Form (CTQ-SF). We compared global cognitive performance as well as scores in seven subdomains (verbal abilities, visuospatial abilities, learning, memory, attention/working memory, executive abilities and processing speed) between participants reporting no CT and those reporting CT experiences using independent samples t-tests as well as linear regression analyses to control for possible confounders. CT subtype physical neglect was associated with attention and working memory after controlling for positive and negative psychosis symptoms, years of education, antipsychotics, gender and age, and adjustment of multiple testing. Our results indicate that the observed heterogeneity in cognitive impairment in SSDs, especially attention/working memory abilities, may in part be associated with childhood physical neglect. Research on childhood trauma and cognitive impairment in SSDs is inconclusive Few studies investigated if CT subtypes (abuse and neglect) could explain the heterogeneity in cognitive impairment in SSDs CT subtype physical neglect was associated with impairment in attention/working memory abilities The observed heterogeneity in cognitive impairment in SSDs may in part be associated with CT subtypes

Abstract
Childhood maltreatment is associated with increased risk for psychiatric and substance use disorders. However, some maltreated individuals appear resilient to these consequences while manifesting the same array of brain changes as maltreated individuals with psychopathology. Hence, a critical issue has been to identify compensatory brain alterations in these resilient individuals. We recently reported that maltreatment is associated with a more vulnerable structural brain network architecture. Resilient individuals have this same vulnerability but appeared to be able to effectively compensate due to reduced nodal efficiency (ability of a node to influence the global network) in 9 specific brain regions that moderate the relationship between maltreatment and psychopathology. Following up we now report that network vulnerability increases progressively during late adolescence to plateau at about 21 years of age, which may help to explain age of onset of psychopathology. Further, we found that network vulnerability was most significantly affected by parental verbal abuse between 16-18 years of age and number of types of maltreatment during childhood. Asymptomatic individuals with no history of psychopathology had more prominent alterations in nodal efficiency than asymptomatic individuals with prior history, who specifically showed reduced nodal efficiency in right amygdala and right subcallosal gyrus. Experiencing inadequate financial sufficiency during childhood increased risk of susceptibility versus resilience by 2.98-fold (95% CI 1.49-5.97, p = 0.002) after adjusting for differences in exposure to maltreatment. Interestingly, adequate-to-higher financial sufficiency appeared to be protective and was associated with reduced nodal efficiency in the right postcentral gyrus and subcallosal gyrus 'resilience' nodes.

Abstract
PURPOSE Adverse childhood experiences in sensitive periods of the developing brain render the individual at a life-long risk for a broad spectrum of aberrant health outcomes. However, there is a lack of scales for the comprehensive assessment of adverse childhood experiences providing information of various types and the age of occurrence. Based on the complete, experimental version of the Maltreatment and abuse chronology of exposure (MACE-X) scale, the present study aimed to develop and psychometrically test a Norwegian version of MACE. METHODS The 75-item MACE-X was translated from German to Norwegian and administered as a self-report measure to 90 outpatients and 145 employees at a Division of specialized mental health care in South-Eastern Norway. The outpatients also completed the Childhood trauma questionnaire (CTQ) and the Symptom checklist 90 (SCL-90) to investigate convergent and predictive validity. To investigate test-retest reliability, outpatients completed MACE once more two weeks later. RESULTS Rasch analysis and Anderson likelihood ratio tests on the combined outpatient and employee data resulted in a 55 item version of the Norwegian MACE. In the outpatient group, test-retest reliability of the MACE-55 was excellent for total scores (ICC ≥ 0.94) and good to excellent for 10 subscale scores (ICC ≥ 0.82). Convergent validity with the CTQ was moderate to high for both total scores (0.63 ≥ r ≥ 0.86) and subscale scores (0.56 ≥ r ≥ 0.82). As compared to CTQ total scores, a MACE total score that combined severity and duration of exposure was numerically more strongly associated with overall psychiatric symptoms and each of nine symptom domains on the SCL-90. CONCLUSIONS The newly developed Norwegian MACE comprehensively assesses past exposure to adverse childhood experiences with high psychometric properties. This scale is a useful tool for research questions addressing sensitive periods for childhood adversities and associated health phenotypes.

Abstract
Childhood trauma has been shown to have detrimental consequences on mental health. It is unknown what impact childhood trauma may have on the early trajectory of serious mental illness (SMI). The purpose of this article is to estimate the baseline prevalence, perceived impact, and duration of trauma that occurred before the age of 18 years in youth at risk for SMI using a transdiagnostic approach. This study included 243 youths, ages 12 to 25 years (42 healthy controls, 43 non-help-seeking individuals [stage 0], 52 help-seeking youth experiencing distress and possibly mild symptoms of anxiety or depression [stage1a], and 108 youth demonstrating attenuated symptoms of an SMI such as bipolar disorder or psychosis [stage 1b]). Participants completed an adapted version of the Childhood Trauma and Abuse scale. There were high frequencies of reported trauma across all stages. Symptomatic individuals experienced more trauma and bullying. Stage 1b individuals reported more physical abuse. Stage 1b also indicated psychological bullying to have a longer duration and impact on their lives. Future work should aim to clarify the complex interrelations between trauma and risk of SMI.

Abstract
BACKGROUND A higher incidence of childhood trauma (CT) has been reported in first episode of psychosis (FEP). There is, however, a lack of knowledge about the synergetic effect between CT and recent stressful events (RSE). METHODS Information on specific types of CT (under 17 years) and RSE (within the past 3 years) was available for 290 FEP patients and 52 healthy controls (HC). Cognitive function at baseline was assessed through a comprehensive neuropsychological test battery. RESULTS While 45.2% of FEP patients and 25% of HC reported at least one CT event, 62.7% of FEP and 21.2% of HC reported an RSE. Meanwhile, 36.2% of FEP patients and 9.6% of HC encountered both childhood and recent stressful events. The patients that just reported CT showed normality in all but the verbal memory cognitive domain; those with additive CT and RSE presented worse general cognitive function, specifically on working memory, processing speed, and executive function. RSE and general cognitive dysfunction were significant determinants of psychosis onset. CONCLUSIONS These results support a synergetic influence of trauma and stressful events on brain function and allow a better understanding of mediators for psychotic disorders useful in the design of specific strategies based on stress-targeted therapies.

Abstract
Background: Schizophrenia spectrum disorders (SSD) are mental diseases caused by a combination of genetic susceptibility and a number of environmental factors. Among these factors, the role of traumatic events suffered in childhood, as well as that of substance use, have been of particular research interest. Objectives: To conduct a systematic review to clarify whether there is an interaction between childhood trauma and substance use related to the diagnosis or symptoms of SSD. It was also the objective of this review to collate the associations that may exist between the three variables of the study (trauma, substance use and psychosis). Methods: We conducted a systematic search resulting in 240 articles. We considered all of the original articles that explored childhood trauma and substance use in patients suffering from SSD. Results: Twenty-three articles were selected for this review. Several of the reviewed papers found associations between childhood trauma and substance use with SSD, as well as interactions between trauma and drug use on SSD. Conclusions: The results suggest that childhood trauma and substance use may be present at the basis of psychosis. This double hit on the pathogenesis could have clinical implications, since each of these impacts could be considered a window of opportunity for the primary prevention of SSD.

Abstract
OBJECTIVE Childhood maltreatment (CM) plays an important role in the aetiology and course of psychotic disorders and is associated with characteristics that could be relevant for treatment. We aimed to conduct a systematic review and meta-analysis on the association between CM and treatment outcome in psychotic disorders. METHODS Treatment outcome was defined as change in psychotic symptoms or in social or occupational functioning between first and last reported measurement in the course of a pharmacological and/or psychological treatment. RESULTS Twelve treatment results from seven studies (636 patients, average treatment duration: 59.2 weeks) were included. CM was related to poorer treatment outcomes in psychotic disorders (OR = 1.51, 95% CI = [1.08, 2.10]). There is evidence that this association might increase with illness duration and increasing age and might be stronger in schizophrenia samples. CONCLUSIONS Childhood maltreatment is highly understudied with regard to treatment outcome in psychotic disorders. The need for more studies is emphasized by the fact that this meta-analysis reveals evidence for a poorer treatment response in patients with CM. If this association is confirmed, the identification of patients with CM and the consideration of associated clinical and biological conditions could contribute to improve treatment outcome in psychotic disorders.

Abstract
IMPORTANCE Abnormalities in amygdala response to threatening faces have been observed in anxiety disorders, autism, bipolar disorder, depression, posttraumatic stress disorder, and schizophrenia. Abnormally hyperactive and hypoactive responses have typically been associated with anxiety and inhibition vs risk taking and inappropriate social behaviors. Maltreatment is a major risk factor for most of these disorders and is associated with abnormal amygdala function. OBJECTIVE To identify the type and age of exposure to childhood maltreatment that are associated with hyperactive and hypoactive amygdala responses in young adulthood. DESIGN, SETTING, AND PARTICIPANTS Data collection for this retrospective cohort study took place from November 8, 2010, to August 23, 2012. Data analyses were conducted from September 20, 2012, to June 27, 2018. Participants were recruited from the urban and suburban Boston vicinity without diagnostic restrictions based on exposure history. EXPOSURES The Maltreatment and Abuse Chronology of Exposure (MACE) scale was used to retrospectively assess type and age of exposure to childhood maltreatment. MAIN OUTCOMES AND MEASURES Activation and pattern information functional magnetic resonance imaging were used to assess bilateral amygdala response to angry and fearful faces vs neutral faces or shapes, and sensitive exposure periods were identified using cross-validated artificial intelligence predictive analytics (50 averaged randomized iterations with training on 63.3% and testing on 36.7% of the sample). RESULTS Of the 202 participants (mean [SD] age, 23.2 [1.7] years; 118 [58.4%] female), 52 (25.7%) reported no exposure to maltreatment and 150 (74.3%) reported exposure to 1 or more maltreatment types. Eight participants (15.1%) with a MACE score of 0 and 51 (34.2%) with a MACE score of 1 or higher had a history of major depression (odds ratio, 2.40; 95% CI, 1.05-6.06; P = .03); 8 unexposed participants (15.1%) and 46 with MACE scores of 1 or higher (30.9%) had a history of 1 or more anxiety disorders (odds ratio, 2.45; 95% CI, 1.03-6.50; P = .03). Retrospective self-report of physical maltreatment between 3 and 6 years of age and peer emotional abuse at 13 and 15 years were associated with amygdala activation to emotional faces vs shapes. Early exposure was associated with blunted response (β = -0.17, P < .001), whereas later exposure was associated with augmented response (β = 0.16, P < .001). Prepubertal vs postpubertal maltreatment was associated with an opposite response on the voxelwise response pattern in clustering stimuli of the same type (eg, mean [SD] emotional ellipse areas for physical maltreatment at age 4 years vs nonverbal emotional abuse at 13 years: 1.41 [1.05] vs 0.25 [0.10], P < .001) and in distinguishing between stimuli of different types (eg, mean [SD] emotional vs neutral faces distance for peer emotional abuse at age 6 years vs 13 years: 1.89 [0.75] vs 0.80 [0.39], P < .001). CONCLUSIONS AND RELEVANCE The findings suggest that prepubertal vs postpubertal developmental differences in the association between maltreatment and amygdala response to threatening or salient stimuli exist. Understanding the role of adversity in different sensitive exposure periods and the potential adaptive significance of attenuated vs enhanced amygdala response may help explain why maltreatment may be a risk factor for many different disorders and foster creation of targeted interventions to preempt the emergence of psychopathology in at-risk youths.

Abstract
Accumulating evidence indicates systemic biological dysregulations in patients with psychosis that have been conceptualized as the "allostatic load" (AL) index. We aimed to investigate the AL index in 37 subjects at familial high risk of psychosis (FHRP), 42 first-episode psychosis (FEP) patients, 25 acutely relapsed schizophrenia (SCZ-AR) patients and 42 healthy controls (HCs), taking into account psychopathology and cognitive impairment. The AL index was calculated based on 15 biomarkers (cardiovascular markers, anthropometric measures, inflammatory markers, glucose homeostasis parameters, lipids and steroids). Cognition was assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The AL index was significantly higher in patients with psychosis and FHR-P individuals compared to HCs. Patients with FEP and FHR-P individuals had similar AL index. Moreover, the AL index was significantly higher in SCZ-AR patients compared to other groups of participants. Higher AL index was associated with more severe general psychopathology and depressive symptoms, lower scores of attention (total score, digit span and digit coding tasks) and semantic fluency, as well as worse general functioning in patients with psychosis. There was a significant negative correlation between the AL index and the scores of attention (total score and digit coding task) in FHR-P individuals. No significant correlations between the AL index and cognition were found in HCs. Our results indicate that biological dysregulations, captured by the AL index, appear already in FHR-P individuals and progress with psychotic exacerbations. Elevated AL index might contribute to cognitive impairments in FHR-P individuals and patients with psychosis.

Abstract
BACKGROUND The significance of the timing and chronicity of childhood adversity for depression outcomes later in life is unclear. Identifying trajectories of adversity throughout childhood would allow classification of children according to the accumulation, timing, and persistence of adversity, and may provide unique insights into the risk of subsequent depression. METHODS Using data from the Avon Longitudinal Study of Parents and Children, we created a composite adversity score comprised of 10 prospectively assessed domains (e.g., violent victimization, inter-parental conflict, and financial hardship) for each of eight time points from birth through age 11.5 years. We used semiparametric group-based trajectory modeling to derive childhood adversity trajectories and examined the association between childhood adversity and depression outcomes at the age of 18 years. RESULTS Among 9,665 participants, five adversity trajectories were identified, representing stable-low levels (46.3%), stable-mild levels (37.1%), decreasing levels (8.9%), increasing levels (5.3%), and stable-high levels of adversity (2.5%) from birth through late childhood. Approximately 8% of the sample met criteria for probable depression at 18 years and the mean depression severity score was 3.20 (standard deviation = 3.95, range 0-21). The risk of depression in young adulthood was elevated in the decreasing (odds ratio [OR] = 1.72, 95% confidence interval [CI] = 1.19-2.48), increasing (OR = 1.81, 95% CI = 1.15-2.86), and stable-high (OR = 1.80, 95% CI = 1.00-3.23) adversity groups, compared to those with stable-low adversity, when adjusting for potential confounders. CONCLUSIONS Children in trajectory groups characterized by moderate or high levels of adversity at some point in childhood exhibited consistently greater depression risk and depression severity, regardless of the timing of adversity.

Abstract
BACKGROUND In humans, accumulated adverse experiences during childhood increase the risk of anxiety disorders and attention-deficit/hyperactivity disorder. In rodents, the ventral hippocampus (vHIP) is associated with anxiety regulation, and lesions in this region alter both anxiety-like behavior and activity levels. Neuronal oscillations in the vHIP of the theta frequency range (4-12 Hz) have been implicated in anxious states and derive in part from the activity of inhibitory interneurons in the hippocampus, some of which are enwrapped with perineuronal nets (PNNs), extracellular matrix structures known to regulate plasticity. We sought to investigate the associations among early life stress-induced anxiety and hyperactivity with vHIP neuronal oscillations, inhibitory interneurons, and PNNs in mice. METHODS We used repeated maternal separation with early weaning (MSEW) to model accumulated early life adversity in mouse offspring and studied the underlying cellular and electrophysiological changes in the vHIP that are associated with excessive anxiety and hyperactivity. RESULTS We found increased anxiety-like behavior and activity levels in MSEW adult males, along with increased theta power and enhanced theta-gamma coupling in the vHIP. MSEW mice showed reduced intensity of parvalbumin as well as increased PNN intensity around parvalbumin-positive interneurons in the vHIP. We further observed that MSEW increased orthodenticle homeobox protein 2, a transcription factor promoting PNN development, in the choroid plexus, where it is produced, as well as in parvalbumin-positive interneurons, where it is sequestered. CONCLUSIONS These findings raise the possibility of causal links among parvalbumin-positive interneurons, PNNs, orthodenticle homeobox protein 2, and MSEW-induced anxiety and hyperactivity.
