Abstract
Background People who have encountered adverse childhood experiences (ACEs) are predisposed to developing schizophrenia, experiencing exacerbated symptoms, and facing an elevated risk of disease relapse. It is imperative to evaluate the prevalence of ACEs to comprehend the specific attributes of this condition and enable the implementation of suitable interventions. Aims The aim of this study was to assess the prevalence of ACEs and its determinants among people with schizophrenia and the patient attendants in Bahir Dar, Ethiopia. Method A comparative cross-sectional study was carried out at the Comprehensive Specialized Hospitals in Bahir Dar, Ethiopia, from April 26 to June 10, 2023. A total of 291 individuals with schizophrenia and 293 individuals from the patient attendants were selected using a systematic random sampling method. A proportional odds model ordinal logistic regression analysis was used to identify the factors associated with ACEs. Results The occurrence of at least one ACE among individuals diagnosed with schizophrenia was 69.4%, while patient attendants had a 46.8%, as indicated by the Chi-square test, which showed a significant difference at p <0.05. The study findings indicated that individuals with schizophrenia who have encountered four or more ACEs are more inclined to have lower educational attainment (AOR: 4.69 [1.94 - 11.61]), low resilient coping mechanisms (AOR: 2.07 [1.11 - 3.90]), and poor social support (AOR: 3.93 [2.13 - 7.32]). Conversely, factors such as rural residency, illiteracy, and heightened attachment-related anxiety were found to be notably associated with the patient attendants. Conclusion In this study, the substantial prevalence of ACEs emphasized the necessity for ACE screening and the implementation of evidence-based interventions to address and alleviate the overall burden of ACEs.

Abstract
BACKGROUND Maladaptive cognitions about the self and others are associated with a wide array of dysfunctional responses and psychopathological symptoms in non-clinical and clinical samples. Dissociative experiences (e.g., depersonalization and derealization) as a coping response to stressful situations lie on a continuum from healthy to unhealthy but are generally elevated in individuals experiencing mental illness. However, the extent to which Dialectical Core Schemas explain the relationship between dissociative experiences and symptomatology is unclear. Therefore, this study aimed to investigate the mediating role of Dialectical Core Schemas on the relationship between dissociative experiences and symptomatology. METHODS A community sample of 179 participants were recruited (Mage = 21.2 years, SD = 8.2). Data were gathered through self-report questionnaires using a cross-sectional design. RESULTS Maladaptive core schemas about self and others correlated positively with all dissociative experiences (e.g., depersonalization/derealization, amnesia), while adaptive core schemas about the self correlated negatively with depersonalization/derealization and distractibility. Maladaptive core schemas mediated the relationship between dissociative experiences and symptomatology. CONCLUSIONS The relationships between dissociative experiences and symptomatology are bi-directional. Exploring the mediating factors may help clinicians and researchers better understand how to enhance case conceptualization and clinical decision-making.

Abstract
There is growing clinical interest in addressing relationship dynamics between service-users and their voices. The Talking With Voices (TwV) trial aimed to establish feasibility and acceptability of a novel dialogical intervention to reduce distress associated with voices amongst adults diagnosed with schizophrenia spectrum disorders. The single-site, single-blind (rater) randomised controlled trial recruited 50 participants who were allocated 1:1 to treatment as usual (TAU), or TAU plus up to 26 sessions of TwV therapy. Participants were assessed at baseline and again at end of treatment (six-months). The primary outcomes were quantitative and qualitative assessments of feasibility and acceptability. Secondary outcomes involved clinical measures, including targeted instruments for voice-hearing, dissociation, and emotional distress. The trial achieved 100 % of the target sample, 24 of whom were allocated to therapy and 26 to TAU. The trial had high retention (40/50 [80 %] participants at six-months) and high intervention adherence (21/24 [87.5 %] receiving ≥8 sessions). Signals of efficacy were shown in targeted measures of voice-hearing, dissociation, and perceptions of recovery. Analysis on the Positive and Negative Syndrome Scale indicated that there were no differences in means of general psychosis symptom scores in TwV compared to the control group. There were four serious adverse events in the therapy group and eight in TAU, none of which were related to study proceedings. The trial demonstrates the acceptability of the intervention and the feasibility of delivering it under controlled, randomised conditions. An adequately powered definitive trial is necessary to provide robust evidence regarding efficacy evaluation and cost-effectiveness. Trial registration: ISRCTN 45308981.

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
We present a case study of the remission of a chemically resistant schizophrenia disorder after a single session of EMDR. Our patient had been followed-up for schizophrenia according to DSM5 criteria, since 4 years. During our subject's fourth hospitalization for major delirious decompensation, a single EMDR session, according to the standard protocol, resulted in a complete and total remission of the delirious disorder and the disorganization/dissociative syndrome in 8 weeks. This allowed us to interrupt the patient's antipsychotic treatment without relapse at 18 months. This case study allows us to highlight, as many authors have previously done, the necessity of researching the traumatic history of patients diagnosed with schizophrenia in order to provide therapies focused on traumatic dissociation. It also questions the relevance of our diagnostic criteria for schizophrenia and other dissociative disorders.

Abstract
OBJECTIVE Negative auditory verbal hallucination (AVH) content is a major predictor of distress and typically occurs more frequently than positive or neutral content. Recent research has found that negative views of self are associated with the negative content of AVHs. However, research investigating the role of self in AVH content is in its infancy and warrants further study. DESIGN The current study examined correspondence between negative voice content and internalized representations of self, using a self-discrepancy paradigm incorporating multiple domains of self (ideal, ought, and feared). It also considered the impact of depression and anxiety. METHOD An adapted self-discrepancy questionnaire was administered to a transdiagnostic clinical sample of 86 current voice-hearers. Participants rated how similar they believed themselves to be (actual self), and how similar their voices would say they are (voice self), to their ideal, ought, and feared self-concepts. RESULTS Voice content was related to how the person viewed themselves in relation to their ideal, ought, and feared self-concepts. Additionally, voices reflected negative feared self-concepts, particularly in people with anxiety. CONCLUSIONS These findings provide further insight into the phenomenon of hearing voices and have the potential to change the way we approach formulation and treatment of AVHs. In particular, treatment approaches that reduce discrepancies between how one views themselves and their positive and negative self-concepts, or alter the relationship one has with their self-concepts and negative voices, have the potential to reduce the impact of distressing voices. PRACTITIONER POINTS Voice experiences can be meaningfully related to how the person views themselves in relation to concepts of their ideal, ought, and feared selves Negative voice content might be understood as reflecting discrepancies from these self-representations, which may have a self-regulatory function in relation to goal-directed behaviour. Identifying how voice content relates to self could be useful in not only challenging the extent of perceived self-discrepancies, but also considering how to enact valued parts of self.

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
BACKGROUND Schema Therapy is based on the theory that trauma and neglect in childhood lead to early maladaptive schemas and psychopathology in adulthood. The aim of this review was to evaluate support for this theory by synthesizing the literature on childhood adversity and schemas. METHODS A systematic review and meta-analysis were completed in compliance with PRISMA. PsycInfo, CINAHL and PubMed were searched to identify eligible studies that reported unadjusted association(s) between adverse childhood events and schema scores when participants were 18 years or older. Meta-analyses were conducted to estimate the pooled effect size of associations between schemas and experiences of childhood adversity. RESULTS A total of 33 studies met inclusion criteria and provided sufficient data for meta-analyses on childhood experiences relating to toxic frustration of needs (emotional neglect and physical neglect) and trauma and victimization (emotional abuse, physical abuse and sexual abuse). Of the 124 meta-analyses, 65 indicated that schemas show small to large correlations with emotional neglect (range: r = .16 [Failure] to r = .51 [Emotional Deprivation]); small to moderate correlations with emotional abuse (range: r = .20 [Vulnerability to Harm] to r = .44 [Emotional Deprivation]); and small correlations with physical neglect, physical abuse and sexual abuse (range: r = .16 [Vulnerability to Harm] to .26 [Emotional Deprivation and Social Isolation]). CONCLUSIONS Of the 33 included studies, only one used a longitudinal design. However, based on the correlational studies available, early maladaptive schemas in adulthood are associated with a history of childhood abuse and neglect.

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
Auditory verbal hallucinations (AVHs, or hearing voices) are particularly characterized by negative content such as criticism and threats. The extent of negative content is a major predictor of distress, yet there is limited research on what contributes to the content of AVHs. The current study aimed to assess the relationships between childhood trauma, attachment styles (anxious and avoidant) and negative self schemas as plausible mechanisms underlying negative AVH content. Structural equation modelling was used to test a theoretical model, including these constructs, in a transdiagnostic sample of 140 people with AVHs. Findings indicated that collectively, emotional trauma during childhood, insecure anxious attachment and negative self schemas predicted the proportion of negative AVH content experienced by voice hearers. Whereby, trauma predicted attachment, which predicted schemas and in turn negative AVH content. This study marks an important step towards understanding the underlying mechanisms involved in negative AVHs. The results highlight the importance of recognising early experiences of trauma, adult attachment styles and self schemas in developing formulations and effective treatments for negative and distressing AVHs. Psychological interventions that target these underlying mechanisms of negative AVHs may lead to a reduction in negative content, thereby reducing voice related distress.

Abstract
The association between childhood adversity (CA) and psychosis has been extensively investigated in recent years. An increasing body of research has also focused on the mediating or moderating role of biological and psychological mechanisms, as well as other risk factors that might account for the link between CA and psychosis. We conducted a systematic search of the PsychINFO, Embase, Ovid, and Web of Science databases for original articles investigating the role of genetic vulnerabilities, environmental factors, psychological and psychopathological mechanisms in the association between CA and psychosis up to August 2019. We included studies with individuals at different stages of the psychosis continuum, from subclinical psychotic experiences to diagnosed disorders. From the 28 944 records identified, a total of 121 studies were included in this review. Only 26% of the studies identified met the criteria for methodological robustness. Overall, the current evidence suggests that CA may be associated with psychosis largely independently of genetic vulnerabilities. More consistent and robust evidence supports interaction between early and recent adversities, as well as the mediating role of attachment and mood symptoms, which is suggestive of an affective pathway between CA and psychosis across the continuum from subclinical experiences to diagnosable disorder. This review highlighted numerous methodological issues with the existing literature, including selection bias, heterogeneity of measurement instruments utilised, and lack of control for potential confounders. Future research should address these limitations to more accurately estimate mediation and moderation effects on the CA-psychosis association to inform the development of preventive interventions.

Cognitive mediators of the relationship between adverse childhood experiences and adult psychopathology: A systematic review. Dev Psychopathol 2019; 32:1017-1029.

Abstract
AbstractThis is the first review to rigorously examine the mediating role of cognitive factors in the relationship between childhood trauma and subsequent adult psychopathology, and highlight areas for future research. A database search (Child Development & Adolescent Studies, ERIC, Global Health, PsycARTICLES, and PsycINFO) was conducted to identify empirical studies on cognitive factors, explaining the relationship between different types of adverse childhood experiences and adult psychopathology across clinical and nonclinical populations. A narrative synthesis and appraisal of the methodological quality of the studies was conducted. Ninety-eight mediation studies were identified, comprising 4,137 clinical and 28,228 nonclinical participants. Despite great variation in methodological quality of the studies, our narrative synthesis suggests that cognitive factors mediate the relationship between early trauma and later psychopathology. This finding is consistent across different measures of traumatic experiences, psychopathology, and cognitive mediators. Cognitive mediators represent potentially valuable intervention targets for (non)clinical patients who have experienced childhood adversity. Future studies are needed to (a) establish longitudinal causal connections, and (b) assess the effect of interventions that specifically target cognitive change in patients with different levels and types of pathology.

Preliminary Evidence for the Cognitive Model of Auditory Verbal Hallucinations in Youth With Borderline Personality Disorder. Front Psychiatry 2019; 10:292. [PMID: 31156473 PMCID: PMC6531498 DOI: 10.3389/fpsyt.2019.00292] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Accepted: 04/15/2019] [Indexed: 12/17/2022] Open
Abstract
Objectives: This is the first study to explore cognitive, emotional, and behavioral responses to voices in youth with borderline personality disorder (BPD) compared with those with schizophrenia spectrum disorder (SZ), and to examine if negative appraisals of voices predict depression and anxiety across the groups. Methods: The sample comprised 43 outpatients, aged 15-25 years, who reported auditory verbal hallucinations (AVH) and were diagnosed with either Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) BPD or SZ. Data were collected using the Psychotic Symptom Rating Scales, the revised Beliefs About Voices Questionnaire, the Voice Rank Scale, and the Depression Anxiety Stress Scale. Results: Youth with BPD did not differ from youth with SZ in beliefs about the benevolence or malevolence of voices. Youth with BPD appraised their voices as more omnipotent and of higher social rank in relation to themselves, compared with youth with SZ. In both diagnostic groups, beliefs about malevolence and omnipotence of voices were correlated with more resistance toward voices, and beliefs about benevolence with more engagement with voices. In addition, perceiving the voices as being of higher social rank than oneself and negative voice content were both independent predictors of depression, irrespective of diagnostic group. In contrast, negative appraisals of voices did not predict anxiety after adjusting for negative voice content. Conclusions: This study replicated the link between negative appraisals of voices and depression that has been found in adults with SZ in a mixed diagnostic youth sample. It, thus, provides preliminary evidence that the cognitive model of AVH can be applied to understanding and treating voices in youth with BPD.

Early maladaptive schemas in patients with schizophrenia and non-patients with high and low schizotypal traits and their differences based on depression severity. Compr Psychiatry 2019; 88:1-8.

Abstract
BACKGROUND The aims of this study were to predict positive and negative symptoms of psychosis via early maladaptive schemas (EMSs) in patients with schizophrenia (SZ); to compare EMSs among SZ patients, non-patients with high schizotypal traits, and non-patients with low schizotypal traits; and to compare EMSs among subgroups concerning depression severity. METHODS We applied three groups of participants including SZ patients (n = 105), non-patients with low schizotypal traits (n = 90), and non-patients with high schizotypal traits (n = 90). Participants completed the Young Schema Questionnaire-Short Form (YSQ-SF), the Positive and Negative Syndrome Scale (PANSS), the Schizotypal Personality Scale (STA), and the Beck Depression Inventory-II (BDI-II). RESULTS The results indicated that the mistrust/abuse and social isolation schemas were significant predictors of positive and negative symptoms in SZ patients respectively. SZ patients and non-patients with high schizotypal traits exceeded non-patients with low schizotypal traits on all EMSs. There were no differences between SZ patients and non-patients with high schizotypal traits regarding EMSs. In the subgroups with high depression, SZ patients showed higher levels of EMSs than non-patients with low and high schizotypal traits. In the subgroups with low depression, both SZ patients and non-patients with high schizotypal traits had higher scores on EMSs than non-patients with low schizotypal traits. CONCLUSION The findings suggest that mistrust/abuse and social isolation may be specific to psychosis symptoms. Also, SZ and schizotypal traits may overlap in relation to EMSs. In addition, the activated EMSs may contribute to high depression in SZ.

Abstract
PURPOSE OF REVIEW Schema therapy conceptualizes personality disorders in terms of modes and underlying schemas. This article reviews the literature on schema therapy conceptualization of personality disorder functioning and traits, and proposes how these findings apply to novel personality disorder classification in ICD-11 and the DSM-5 Alternative Model of Personality Disorders (AMPD). RECENT FINDINGS Maladaptive schemas and modes are generally associated with personality dysfunction and traits in conceptually coherent ways. The healthy adult mode, a transdiagnostic core concept in schema therapy, corresponds to the ICD-11 and DSM-5-AMPD features of core personality functioning. Modes and underlying schemas substantially overlap with specific ICD-11 and DSM-5-AMPD traits, which denote individual themes and styles of personality dysfunction. SUMMARY The dimensional personality disorder framework in ICD-11 and DSM-5-AMPD is largely compatible with the schema therapy model. The ICD-11 and DSM-5-AMPD provide a scientifically derived and theory-free framework for all practitioners, which may be connected to clinical theory of schema therapy in a coherent manner. Level of personality functioning can be conceptualized as healthy adult functioning (e.g. sense of identity, self-worth, emotion regulation, intimacy, and fulfillment), which inform intensity of treatment. Trait qualifiers can be conceptualized by associated modes (e.g., compliant surrender) and underlying schemas (e.g. abandonment), which inform focus and style of treatment.
