Childhood trauma increases the risk of post-traumatic stress disorder in response to first-episode psychosis

Effect of childhood emotional abuse on depression and anxiety in adulthood is partially mediated by neuroticism: Evidence from a large online sample

Childhood trauma is widely recognized as a potential risk factor for psychiatric illness in adulthood, yet the precise mechanisms underlying this relationship remain incompletely understood. One proposed mechanism involves the impact of childhood trauma on personality development, particularly in relation to neuroticism, which may subsequently heighten susceptibility to psychiatric disorders. In this study, we aimed to investigate this hypothesis through an online survey involving 1116 participants (232 male, 21 %). Participants completed the Childhood Trauma Questionnaire (CTQ), assessing emotional abuse, physical abuse, sexual abuse, emotional neglect, and physical neglect, along with the Trait Self-Description Inventory (TSDI) for personality assessment and the PHQ-9 and GAD-7 clinical questionnaires for depression and anxiety symptoms evaluation, respectively. Our analyses revealed significant positive correlations between all facets of childhood trauma and neuroticism (all p < .01). Linear regression analysis demonstrated that emotional abuse significantly contributed to neuroticism (β = 0.267, p < .05), openness (β = 0.142, p < .05), and agreeableness (β = 0.089, p < .05), while sexual abuse was associated with agreeableness (β = 0.137, p < .01) Emotional neglect was negatively correlated with conscientiousness (β = -0.090, p < .01), extroversion (β = -0.109, p < .01) and agreeableness (β = -0.154, p < .01). Furthermore, linear regression analysis revealed that emotional abuse was positively and significantly correlated with PHQ-9 and GAD-7 scores (r = 0.330, p < .01 and r = 0.327, p < .01, respectively). Mediation analysis supported a significant mediating role of neuroticism in the association between childhood emotional abuse and both depression (PHQ-9) (z = 8.681, p < .01) and anxiety (GAD-7) (z = 9.206, p < .01). Notably, the correlation between childhood emotional abuse and psychiatric symptoms was attenuated but not eliminated after controlling for neuroticism, suggesting partial mediation. While our cross-sectional design precludes causal inference, our findings support the notion that childhood emotional abuse may contribute to increased neuroticism, thereby elevating vulnerability to affective disorders in adulthood. These results underscore the importance of considering personality factors in understanding the long-term consequences of childhood trauma on mental health outcomes.

Childhood Trauma in Clozapine-Resistant Schizophrenia: Prevalence, and Relationship With Symptoms

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.

"They may be confronting but they are good questions to be asking" young people's experiences of completing a trauma and PTSD screening tool in an early psychosis program

BACKGROUND

There is a history of inadequate enquiry about, and assessment of, trauma in young people within Early Psychosis services and even when screening does occur there is little known about how young people experience this process.

AIMS

This study aimed to explore young people's experiences of completing a trauma and PTSD screening tool when receiving a service in an Early Psychosis Program.

METHOD

Semi-structured interviews were conducted with 10 young people, aged 18-24 years, to explore their subjective experience of this process. Transcripts were analysed via interpretative phenomenological analysis.

RESULTS

Four super-ordinate themes were identified: (i) an emotional experience, (ii) the importance of the relationship with the clinician, (iii) an opportunity to reflect on past experiences, and (iv) the ability to be able to provide honest responses. Results from this study indicated that young people expected to be asked about their trauma experiences, acknowledged that this was challenging for them but found that this was made easier due to the relationship they had built with the clinician, the timing of the screening and also, possibly, by the written style format of the questionnaires.

CONCLUSIONS

Young people in this study accepted the need for screening for traumatic histories, and expected to be asked about their traumatic experiences, despite the possibility of a short-term increase in distress. The support offered by a trusted clinician, whom the young person had built a relationship with, appeared to be an important component to the willingness and the ability of the young person to complete the questionnaires. This reinforces the fact that screening for trauma in an early psychosis service can be conducted in a way that is safe and acceptable to young people.

Oxytocin receptor genes moderate BDNF epigenetic methylation by childhood trauma

OBJECTIVES

Gene-Environment (G × E) interaction is of increasing importance in understanding the pathophysiology of posttraumatic stress disorder (PTSD). This study investigated the interaction effect of childhood traumatic experience and epigenetic methylation of brain-derived neurotrophic factor (BDNF) and a possible moderating effect of oxytocin receptor (OXTR) gene rs53576.

METHODS

Ninety-nine patients with PTSD and 81 healthy controls (HCs) were recruited. Clinical assessments, including the childhood trauma questionnaire (CTQ) and posttraumatic stress disorder Checklist (PCL) were performed. BDNF methylation and OXTR genotyping (A vs. G allele) were conducted through blood sampling. A two-way multivariate analysis and a moderated regression analysis were conducted to investigate the moderating effect of the OXTR gene on the relationship between CTQ and BDNF methylation.

RESULTS

As for the HC group, the interaction effect of the CTQ and OXTR genotype was significant on BDNF methylation, and the moderation model showed that CTQ and OXTR group are significant predictors of BDNF methylation. In the G-OXTR type, the high CTQ group showed a greater BDNF methylation level. As for the PTSD group, no interaction or moderation effects were found.

LIMITATIONS

The present study did not control the dosage, duration of medications, and different trauma types and the assessment of childhood trauma was based on self-report.

CONCLUSIONS

These results suggested that childhood traumatic experience showed a significant impact on BDNF methylation, and OXTR genes have a moderating effect on this epigenetic mechanism in people who have experienced the childhood traumatic episodes.

Prevalence and clinical implication of adverse childhood experiences and their association with substance use disorder among patients with schizophrenia

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.

Traumatic life events as risk factors for psychosis and ICD-11 complex PTSD: a gender-specific examination

Background

Numerous studies found robust associations between psychosis and posttraumatic stress disorder (PTSD), but few have examined the relationships between psychosis and recently formulated ICD-11 Complex PTSD (CPTSD). Further, no known study has examined the effects of different traumatic life events on CPTSD and psychotic-like symptoms in a manner that permits gender-specific effects to be identified.

Objective

Using a nationally representative sample of 1,020 Irish adults, we examined gender-differences in (a) psychotic-like symptoms, CPTSD, and exposure to 21 different traumatic life events, and (b) the unique associations between different traumas with CPTSD and Psychosis.

Method

Bivariate analyses and structural equation modelling were performed.

Results

Consistent with the literature, no gender differences were observed in psychotic-like symptoms. Females reported slightly higher levels of CPTSD and were more likely to be exposed to sexual and emotional abuse, whereas men reported greater exposure to physical violence, accidents, and disasters. Psychosis symptoms were explained by trauma exposure to a considerate degree and at a level similar to CPTSD; a moderate correlation was also found between CPTSD and Psychosis. Physical/emotional neglect was the only traumatic life event that significantly and most strongly predicted both conditions. Two gender-specific associations between different traumatic life events and CPTSD and Psychosis were identified out of the 42 possible effects modelled.

Conclusions

The present investigation provides initial evidence that psychotic-like symptoms and CPTSD are moderately correlated constructs in the general population. Results also highlight the importance of conducting a detailed assessment of trauma history for all clients presenting with symptoms of CPTSD, psychosis, or both.

Reaching consensus on the principles of trauma-informed care in early intervention psychosis services: A Delphi study

AIM

The current study sought to conceptualize and reach consensus on the principles of trauma-informed care in early intervention psychosis services.

METHODS

A three-phase Delphi method was employed in this study. Experts included researchers, service providers and Experts by Experience in the area of early intervention in psychosis. In the initial qualitative phase, an expert panel (n = 57) shared their views on the constituents of trauma-informed care in early intervention psychosis services. Thematic analysis led to the generation of statement items. The expert panel was asked to rate the extent to which each statement item was an essential principle of trauma-informed care, leading to consensus of endorsed principles.

RESULTS

Qualitative analysis of the first phase data led to the identification of 185 distinct statements which were compiled into an online questionnaire for the panel to rate in Phase 2. The Phase 2 questionnaire was completed by 42 experts, with the endorsement of seven principles. In Phase 3, the panel were invited to re-rate 24 statements. This phase was completed by 39 panel members, with the acceptance of a further nine principles. Consensus was achieved resulting in the endorsement of 16 essential principles of trauma-informed care.

CONCLUSIONS

The study offers novel understanding of the conceptualisation of trauma-informed care in early intervention services and suggests principles which are widely agreed by experts in the field. The recommendations may inform the adoption of consistently delivered trauma-informed care in early interventions in psychosis and facilitate the evaluation and development of services.

Targeting dissociation using cognitive behavioural therapy in voice hearers with psychosis and a history of interpersonal trauma: A case series

OBJECTIVES

Previous studies have suggested that dissociation might represent an important mechanism in the maintenance of auditory verbal hallucinations (i.e., voices) in people who have a history of traumatic life experiences. This study investigated whether a cognitive behavioural therapy (CBT) intervention for psychosis augmented with techniques specifically targeting dissociative symptoms could improve both dissociation and auditory hallucination severity in a sample of voice hearers with psychosis and a history of interpersonal trauma (e.g., exposure to sexual, physical, and/or emotional abuse).

DESIGN

Case series.

METHODS

A total of 19 service users with psychosis were offered up to 24 therapy sessions over a 6-month intervention window. Participants were assessed four times over a 12-month period using measures of dissociation, psychotic symptoms severity, and additional secondary mental-health and recovery measures.

RESULTS

Sixteen participants engaged in the intervention and were included in last-observation-carried-forward analyses. Dropout rates were in line with those of other CBT for psychosis trials (26.3%). Repeated measures ANOVAs revealed large and significant improvements in dissociation (d_rm  = 1.23) and hallucination severity (d_rm  = 1.09) by the end of treatment; treatment gains were maintained 6 months following the end of therapy. Large and statistically significant gains were also observed on measures of post-traumatic symptoms, delusion severity, emotional distress, and perceived recovery from psychosis.

CONCLUSIONS

The findings of this case series suggest that the reduction of dissociation represents a valuable and acceptable treatment target for clients with auditory verbal hallucinations and a trauma history. Future clinical trials might benefit from considering targeting dissociative experiences as part of psychological interventions for distressing voices.

PRACTITIONER POINTS

Practitioners should consider the role of dissociation when assessing and formulating the difficulties of voice hearers with a history of trauma. Techniques to reduce dissociation can be feasibly integrated within psychological interventions for voices. Voice hearers with histories of trauma can benefit from psychological interventions aimed at reducing dissociation.

Trauma and the content of hallucinations and post-traumatic intrusions in first-episode psychosis

OBJECTIVE

Increasing evidence suggests experiences of childhood trauma may be causally related to the development of hallucinations. Cognitive theories of psychosis suggest post-traumatic intrusions to be a primary mechanism in this relationship. These theories predict that the content of hallucinations will be related to traumatic experiences; however, few studies have investigated this. This study examined the relationship between childhood trauma, the content of hallucinations, and the content of post-traumatic intrusions in a sample with first-episode psychosis.

METHODS

Sixty-six young people aged 15-25 experiencing a first episode of psychosis were recruited from an early intervention service. Participants completed assessments of traumatic experiences, hallucination content, and post-traumatic intrusion content using a systematic coding frame. The coding frame assessed for three types of relationships between traumatic experiences, the content of hallucinations, and the content of post-traumatic intrusions: direct relationships (hallucination content exactly matching the trauma/intrusion), thematic relationships (hallucinations with the same themes as the trauma/intrusion), and no relationship (hallucination and trauma/intrusion content unrelated).

RESULTS

Of those people who reported trauma and hallucinations (n = 36), 22 of these (61%) experienced post-traumatic intrusions, and of these, 16 (73%) experienced hallucinations that were directly or thematically related to their post-traumatic intrusions. Twelve people experienced hallucination content directly related to their trauma, six of whom (50%) also had intrusions relating to the same traumatic event as their hallucinations.

CONCLUSIONS

The finding that some people experience hallucinations and post-traumatic intrusions relating to the same traumatic event supports theories proposing a continuum of memory intrusion fragmentation. These results indicate that early intervention services for young people with psychosis should provide assessment and intervention for trauma and PTSD and should consider the impact of past traumatic events on the content of current hallucinatory experience.

PRACTITIONER POINTS

Trauma and post-traumatic stress disorder should be assessed in those experiencing a first episode of psychosis. Interventions for trauma should be offered in early intervention for psychosis services. In a notable proportion of people, hallucination content is related to traumatic experiences. Clinical assessment and formulation of hallucinations requires consideration of how past traumatic events may be contributing to hallucinatory experience. It is important for clinicians to have an understanding of the phenomenological differences between hallucinations and post-traumatic intrusions when conducting clinical assessments with people with comorbid psychosis and PTSD.

Types, prevalence and gender differences of childhood trauma in first-episode psychosis. What is the evidence that childhood trauma is related to symptoms and functional outcomes in first episode psychosis? A systematic review

This paper reviews and discusses the literature on childhood trauma (CT) in people with first-episode psychosis (FEP). The aim is to update the knowledge on the prevalence and the types of CT suffered by FEP people, to compare them with other samples, to study the impact of gender, and to examine the relationship between CT and symptoms and functional outcomes. We conducted a literature search (1995-2019), to identify reported data on any topic related to CT in FEP samples. The following terms were used in the search: CT or sexual abuse or physical abuse or neglect, and first-episode psychosis. We found 493 studies, of which 68 were included in the review. FEP presented a higher prevalence of CT than controls. Women suffer more sexual abuse. The effect of CT on the severity, the prognosis and the evolution of FEP is unclear. FEP have a high prevalence of CT. Its relationship with symptoms and functional outcomes indicates its importance within treatment. This suggests the importance of creating and implementing specific interventions and personalized therapies addressed to work through their past traumatic experiences to improve their quality of live and their prognosis.

A systematic review of PTSD to the experience of psychosis: prevalence and associated factors

BACKGROUND

Psychosis can be a sufficiently traumatic event to lead to post-traumatic stress disorder (PTSD). Previous research has focussed on the trauma of first episode psychosis (FEP) and the only review to date of PTSD beyond the first episode period was not systematic and is potentially outdated.

METHODS

We searched electronic databases and reference lists using predetermined inclusion criteria to retrieve studies that reported prevalence rates and associated factors of psychosis-related PTSD across all stages of the course of psychosis. Studies were included if they measured PTSD specifically related to the experience of psychosis. Risk of bias was assessed using an adapted version of the Newcastle Ottawa Scale. Results were synthesised narratively.

RESULTS

Six papers met inclusion criteria. Prevalence estimates of psychosis-related PTSD varied from 14 to 47%. Studies either assessed first-episode samples or did not specify the number of episodes experienced. Depression was consistently associated with psychosis-related PTSD. Other potential associations included treatment-related factors, psychosis severity, childhood trauma, and individual psychosocial reactions to trauma.

CONCLUSIONS

Psychosis-related PTSD is a common problem in people with psychosis. There is a lack of published research on this beyond first episode psychosis. Further research is needed on larger, more generalizable samples. Our results tentatively suggest that prevalence rates of psychosis-related PTSD have not reduced over the past decade despite ambitions to provide trauma-informed care.

A Multicenter Phase II RCT to Compare the Effectiveness of EMDR Versus TAU in Patients With a First-Episode Psychosis and Psychological Trauma: A Protocol Design

Background

Patients with a first episode psychosis (FEP) who are admitted for the first time to a psychiatric hospital frequently have experienced prior psychological trauma. Additionally, 40-80% develop posttraumatic stress symptoms, which are summarized as a post-psychotic post-traumatic syndrome (PPS). Eye Movement Desensitization and reprocessing (EMDR) therapy could be an effective psychotherapy to treat a PPS and prior psychological traumas in this population.

Objectives

To assess if EMDR therapy leads to: 1) a reduction of relapses after intervention, 2) an improvement of trauma-related, psychotic and affective symptoms, 3) an improvement of overall functioning, and 4) an improvement in quality of life.

Methods

This is a multicenter phase II rater-blinded randomized controlled trial in which 80 FEP patients with a history of psychological trauma will be randomly assigned to EMDR (n = 40) or to TAU (n = 40). Traumatic events will be measured by the Global Assessment of Posttraumatic Stress Questionnaire, the Cumulative Trauma Screening, the Impact of Event Scale-Revised, the Dissociative Experiences Scale, the Childhood Trauma Scale, the Holmes-Rahe Life Stress Inventory, and the Dissociative Experiences Questionnaire. Clinical symptomatology will be evaluated using the Suicide and Drug Consumption module of the International Neuropsychiatric Interview, Structured Clinical Interview for Positive and Negative Syndrome Scale, Young's Scale for Mania Evaluation, and Beck Depression II Questionnaire. Functionality will be assessed with the Global Assessment of Functioning and the Quality of Life with the Standardized Instrument developed by the EuroQol Group. The cognitive insight and adherence to the treatment will be assessed with the Beck Cognitive Insight Scale and the Drug Attitude Inventory. All variables will be measured at baseline, post-treatment and at 12-month follow-up.

Conclusion

This study will provide evidence of whether EMDR therapy is effective in reducing trauma and clinical symptoms, reducing relapses and in improving functionality and quality of life in patients with FEP and a history of trauma.

Psychosis: An Emerging Field for EMDR Research and Therapy

It has only been in this last decade that trauma-focused treatments (TFT) have been studied in patients with psychotic disorders. Before, the paradigm stated that TFT was contraindicated in these patients because clinicians and researchers assumed the risk of exacerbation of symptoms was too high. The purpose of this article is to examine the effectiveness of eye movement desensitization and reprocessing (EMDR) therapy in the treatment of psychosis. To this end, we will present a brief narrative review of the current state of research in this particular field. The results suggest that, contrary to the “no-TFT-in-psychosis” paradigm, TFTs such as EMDR therapy can successfully be used to reduce trauma-related symptoms in patients with psychosis. Moreover, there are now provisional indications that psychotic symptoms such as delusions and hallucinations can be targeted directly and indirectly using EMDR therapy.

Current evidence of childhood traumatic experiences in psychosis - focus on gender differences

Childhood abuse is common among people with psychosis and it is associated with poor illness outcomes. Some forms of childhood abuse are more common in women, but the impact of gender and childhood abuse in psychosis has been little investigated and evidence has never been put into a congruent frame. Herein, we conducted a narrative review to assess the impact of gender and childhood abuse in psychosis. Research articles were identified (n = 44) using a comprehensive electronic search of PubMed, Web-of-Science, Scopus and Cochrane databases. Women appeared to be at greater risk of sexual abuse than men. Women with childhood abuse report more positive and mood symptoms, and more suicide attempts compared to men. In addition, women exposed to childhood abuse display an earlier age of onset compared to not exposed, but this association is not present in men. Conversely, men with childhood abuse show more negative symptoms, substance use and a poorer cognitive performance compared to women. It seems therefore confirmed that gender and childhood abuse may impact on the outcome of psychosis, since not all gender differences found in patients who had been abused in their childhood are accounted by the overall differences between men and women with psychosis.

Talking about trauma in therapy: Perspectives from young people with post-traumatic stress symptoms and first episode psychosis

AIM

Despite recommendations from national guidelines, individuals with first episode psychosis (FEP) are currently unlikely to have the effects of their traumatic experiences assessed and treated within psychosis treatment. This may be due to the mismatch between the objectives of trauma-specific treatments (directly targeting post-traumatic stress symptoms by talking about the trauma) and trauma-informed care (limiting practices that may retraumatise clients). We aimed to gain an understanding of what it was like for young people to talk about trauma in FEP treatment, and how their experiences related to the broad conceptualisations of trauma-informed and trauma-specific treatment approaches.

METHODS

Semi-structured interviews were conducted with eleven participants (18-27 years) with FEP and post-traumatic stress disorder (PTSD) symptoms after the completion of an intervention for the effects of trauma. Transcripts were analysed using an interpretative phenomenological approach.

RESULTS

Two superordinate themes were identified, each with subordinate themes. 1. Reluctance to approach the trauma memory: 1a. Not wanting to talk about trauma; 1b. Difficulty acknowledging that the trauma had occurred; 1c. Not wanting to re-experience emotions associated with trauma. 2. Factors aiding the process: 2a. Desire for change; 2b. Not being pushed to talk; 2c. Valuing the case manager; 2d. Time.

CONCLUSIONS

A majority of participants in the study experienced reluctance when recounting their trauma memories. Being in control of how trauma memories are shared and having time for the therapeutic relationship to develop enhanced participants' readiness for talking about trauma. Incorporating trauma-informed principles and motivational interviewing could aid in facilitating the processes around talking about trauma.

Childhood maltreatment and treatment outcome in psychotic disorders: a systematic review and meta-analysis

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.

Stability of retrospective self-reports of childhood trauma in first-episode psychosis

AIM

Childhood trauma (CT), abuse and neglect are commonly reported by individuals experiencing psychosis. However, there are concerns that acute psychotic symptoms, in particular delusions, may contribute to inaccurate reporting of CT. As a result, individuals experiencing psychosis may not be asked about their experiences of abuse when they are being seen in psychiatric settings. This lack of attention can directly impact on the tailoring of their clinical care. This study aimed to investigate the stability of reports of CT by young people experiencing a first psychotic episode (FEP) compared to healthy comparison subjects.

METHODS

Responses of 24 young people during the acute FEP and 3 months later to items on the Childhood Trauma Questionnaire (CTQ) were compared to 30 non-psychiatric controls. All participants were aged 15 to 25 years.

RESULTS

FEP participants reported higher CT than controls at both time points. Reliability analyses (interclass correlation coefficients [ICCs]) suggested strong agreement between CT reports at baseline and follow-up for FEP participants (.81) and controls (.91). Positive psychotic symptoms were unrelated to CT reports. Although the severity of CT reports fluctuated between assessments, complete retractions of severe abuse claims occurred rarely.

CONCLUSIONS

The results suggest that retrospective self-report can be used to reliably assess CT in young people experiencing acute psychosis.

Predictors and moderators of burden of care and emotional distress in first-episode psychosis caregivers: results from the GET UP pragmatic cluster randomised controlled trial

AIMS

First-episode psychosis (FEP) is a major life event and can have an adverse impact on the diagnosed individual and their families. The importance of intervening early and providing optimal treatments is widely acknowledged. In comparison to patient groups, literature is scarce on identifying treatment predictors and moderators of caregiver outcomes. This study aimed to identify pre-treatment characteristics predicting and/or moderating carer outcomes, based on data from a multi-element psychosocial intervention to FEP patients and carers (GET-UP PIANO trial).

METHODS

Carer demography, type of family relationship, patient contact hours, pre-treatment carer burden, patient perceptions of parental caregiving and expressed emotion (EE) were selected, a priori, as potential predictors/moderators of carer burden and emotional distress at 9 months post treatment. Outcomes were analysed separately in mixed-effects random regression models.

RESULTS

Analyses were performed on 260 carers. Only patient perceptions of early maternal criticism predicted reports of lower carer burden at follow-up. However, multiple imputation analysis failed to confirm this result. For treatment moderators: higher levels of carer burden at baseline yielded greater reductions in carer emotional distress at follow-up in the experimental group compared with treatment as usual (TAU). Higher levels of perceived EE moderated greater reductions in carer reports of tension in experimental group, compared with TAU, at follow-up. In younger caregivers (<51 years old), there were greater reductions in levels of worry during the baseline to follow-up period, within the experimental group compared with TAU.

CONCLUSION

The study failed to identify significant treatment predictors of FEP carer outcomes. However, our preliminary findings suggest that optimal treatment outcomes for carers at first episode might be moderated by younger carer age, and carers reporting higher baseline levels of burden, and where patients perceive higher levels of negative effect from caregivers.

The last taboo: The experience of violence in first-episode psychosis caregiving relationships

OBJECTIVES

Informal caregiving relationships play an important role in facilitating recovery outcomes in psychosis. The relationship can serve as a source of positive experiences that co-exist alongside common challenges typically associated with mental health problems. People with psychosis, when compared to the general population, are more likely to perpetrate acts of violence, a relationship that is particularly evident during the first psychosis episode. Although victims of service user violence are typically people already known to them, such as informal carers, there remains a lack of understanding about their caring experiences and needs. This study sought to address gaps in the literature by exploring the subjective accounts of informal carers supporting a relative experiencing their first episode of psychosis who has also behaved violently towards them.

DESIGN

A cross-sectional design was employed.

METHODS

Individual semi-structured interviews, which were audio recorded and later transcribed for analyses, were undertaken with a convenience sample of eight carers drawn from a specialist early psychosis service. Interview questions focused on their experiences of patient violence, the subjective impact, and coping strategies. An interpretative phenomenological approach was used to analyse the data.

RESULTS

Participants were mostly living with their relative with psychosis and were typically female, parents, and from a black and minority ethnic background. Data analyses identified seven key themes from participant interviews including the lack of predictability over when the violence occurred, being scared and fearful, keeping quiet about what happens at home and in the caregiving relationship, and staying safe.

CONCLUSIONS

Reports by informal carers about experiencing violence and victimization from their relatives with psychosis are an important issue in some caregiving relationships during the first episode. Developing a more informed understanding of the specific needs of these carers and the caregiving relationship is indicated. The implications for service providers are discussed.

PRACTITIONER POINTS

Carers were exposed to a broad range of patient violence, which included being kicked and having weapons used against them. The violence typically occurred within carers' homes, when no other people were around. Patient violence impacted negatively on carer emotional and physical functioning, which included leaving carers living in fear of their own safety and what might become of their relative. The results highlight the importance of routinely asking first-episode carers about their experience of patient violence. The development of interventions (e.g., identification of early triggers, de-escalation) that are able to take account of the ongoing nature and complexity of the caregiving relationship but are purposefully aimed at supporting carers to remain safe in their relationship should be explored for their impact.

Posttraumatic stress disorder with secondary psychotic features (PTSD-SP): Diagnostic and treatment challenges

Trauma exposure leads to various psychiatric disorders including depression, anxiety, bipolar disorders, personality disorders, psychotic disorders, and trauma related disorders, especially posttraumatic stress disorder (PTSD). There are some overlapping symptoms of both PTSD and psychosis that make diagnosis challenging. Despite this overlap, the evidence of PTSD with comorbid psychosis as a distinct entity lies in the research showing biologic, genetic and treatment management differences between psychotic PTSD, non-psychotic PTSD, psychotic disorders and healthy controls. There is emerging evidence that PTSD with secondary psychotic features (PTSD-SP) might be a discrete entity of PTSD with known risk factors that increase its prevalence. This review has presented evidence for individuals with PTSD-SP being distinct in genetics and neurobiological factors. Individuals with PTSD and comorbid psychosis can benefit from evidence based psychotherapy (EBT). There is not enough evidence to recommend second generation antipsychotics (SGA) for PTSD-SP given that risperidone and quetiapine are the only SGAs studied in randomized controlled trials. Hence, developing an operational diagnostic criteria and treatment framework for clinical and research use is critical.

Treating the "E" in "G × E": Trauma-Informed Approaches and Psychological Therapy Interventions in Psychosis

Despite advances in genetic research, causal variants affecting risk for schizophrenia remain poorly characterized, and the top 108 loci identified through genome-wide association studies (GWAS) explain only 3.4% of variance in risk profiles. Such work is defining the highly complex nature of this condition, with omnigenic models of schizophrenia suggesting that gene regulatory networks are sufficiently interconnected such that altered expression of any "peripheral" gene in a relevant cell type has the capacity to indirectly modulate the expression of "core" schizophrenia-associated genes. This wealth of associated genes with small effect sizes makes identifying new druggable targets difficult, and current pharmacological treatments for schizophrenia can involve serious side effects. However, the fact that the majority of schizophrenia genome-wide associated variants fall within non-coding DNA is suggestive of their potential to modulate gene regulation. This would be consistent with risks that can be mediated in a "gene × environment" (G × E) manner. Stress and trauma can alter the regulation of key brain-related pathways over the lifetime of an individual, including modulation of brain development, and neurochemistry in the adult. Recent studies demonstrate a significant overlap between psychotic symptoms and trauma, ranging from prior trauma contributing to psychosis, as well as trauma in response to the experience of psychosis itself or in response to treatment. Given the known effects of trauma on both CNS gene expression and severity of psychosis symptoms, it may be that pharmacological treatment alone risks leaving individuals with a highly stressful and unresolved environmental component that continues to act in a "G × E" manner, with the likelihood that this would negatively impact recovery and relapse risk. This review aims to cover the recent advances elucidating the complex genetic architecture of schizophrenia, as well as the long-term effects of early life trauma on brain function and future mental health risk. Further, the evidence demonstrating the role of ongoing responses to trauma or heightened stress sensitivity, and their impact on the course of illness and recovery, is presented. Finally, the need for trauma-informed approaches and psychological therapy-based interventions is discussed, and a brief overview of the evidence to determine their utility is presented.

Psychotic disorders in sexually abused youth: A prospective matched-cohort study

Child sexual abuse has been identified as a potential risk factor for developing a psychotic disorder. However, little is known about the prevalence of psychotic disorders in youth who were sexually abused during adolescence and young adulthood. Gender differences also remain unclear. This study used administrative databases from a Child Protection Agency and a public health care system. It aimed to investigate the prevalence of psychotic disorders in sexually abused youth between the first substantiated report of sexual abuse and the beginning of adulthood. A second objective was to assess gender differences. Administrative health data for 882 sexually abused youth were compared with 882 matched controls from the general population over a 13-year period using conditional generalized linear mixed models. Stratified analyses by gender (group comparison) and group (gender comparison) were also performed. Sexually abused youth were 10 times more at risk of receiving a diagnosis of psychotic disorder than youth from the general population. There was no gender difference in the prevalence of psychotic disorders among sexually abused youth. These results highlight the importance of targeted prevention of psychotic disorders among sexually abused youth. Future studies should investigate risk factors and developmental trajectories of psychotic disorders in this population.

Does dissociation mediate the relationship between childhood trauma and hallucinations, delusions in first episode psychosis?

BACKGROUND

Childhood trauma has been linked to the presence of delusions and hallucinations in psychosis, although the mechanisms underlying this relationship require elucidation. Dissociation, characterized by disruptions to the integrative functioning of several core mental domains, has emerged as a potential mechanism. There is a paucity of research using a clinician-rated measure of dissociation to test the indirect effect of dissociation on the relationship between childhood trauma and psychotic symptoms. This study aimed to investigate whether dissociation mediated both the relationships between childhood trauma and hallucinations, and childhood trauma and delusions utilizing a clinician-administered measure of dissociation, namely the Structured Clinical Interview for DSM-IV Dissociative Disorders - Revised (SCID-D-R).

METHOD

Sixty-six first-episode psychosis (FEP) participants completed a research interview and questionnaires. Information about experiences of childhood trauma, psychosis, dissociation, general psychopathology and demographics were collected.

RESULTS

When using the SCID-D-R, childhood trauma positively correlated with dissociation. Further, dissociation mediated the relationship between childhood trauma and delusions. Contrary to previous findings, we found no relationship between dissociation and hallucinations and no mediating effect of dissociation on the association between childhood trauma and hallucinations. The results of the SCID-D-R differed significantly from those of the Dissociative Experiences Scale-II (DES-II) which were consistent with previous research.

CONCLUSIONS

Our findings are the first to use a clinician-rated measure to test the mediating effect of dissociation on the relationship between childhood trauma and positive symptoms (i.e., hallucinations and delusions). Given the discrepancies in results between the SCID-D-R and DES-II, how dissociation is measured in future research is an important consideration. The results add to a body of work that increasingly recognizes the importance of dissociative symptoms on the relationship between childhood trauma and psychosis. The results suggest that dissociative symptoms should be part of routine assessment in those with a history of trauma and present to FEP services.

Early maladaptive schemas as mediators between childhood maltreatment and later psychological distress among Chinese college students

The aim of the current study was to examine whether early maladaptive schemas (EMSs) mediate the association between different kinds of childhood maltreatment and later psychopathology and the effect of different kinds of childhood maltreatment on psychological distress in later life. A total of 1102 college students from two local universities participated in the study; their average age was 20.46 ± 1.13 years. The participants completed the Childhood Trauma Questionnaire (CTQ), the Early Maladaptive Schemas Scale (EMSs), the Zung Self-Rating Depression Scale (SDS), and the Zung Self-Rating Anxiety Scale (SAS). Later psychological distress had a significant positive correlation with childhood EMSs, and almost all of the variables measuring childhood maltreatment had a significant positive correlation with EMSs. Structural equation modeling and mediation analyses were conducted based on Bootstrap estimations; the mediation analyses demonstrated the utility of EMSs as the mechanism through which childhood maltreatment has an indirect effect on later psychological distress. Moreover, the study found that emotional abuse had the strongest overall effect of all five types of child maltreatment on later psychological distress, followed in order of magnitude by emotional neglect, physical neglect, sexual abuse, and physical abuse.

The traumatic experience of first-episode psychosis: A systematic review and meta-analysis

INTRODUCTION

A psychotic episode may be sufficiently traumatic to induce symptoms of post-traumatic stress disorder (PTSD), which could impact outcomes in first-episode psychosis (FEP). The objectives of this systematic review and meta-analysis were to estimate the prevalence of PTSD symptoms in relation to psychosis in FEP and to identify risk factors for the development of PTSD symptoms.

METHODS

We searched electronic databases and conducted manual searching of reference lists and tables of contents to identify relevant studies. Quantitative studies were included if the population was experiencing FEP and if PTSD was measured in relation to psychosis. Prevalence of PTSD symptoms and diagnoses were meta-analyzed using a random effects model. Potential risk factors for PTSD symptoms were summarized qualitatively.

RESULTS

Thirteen studies were included. Eight studies assessed PTSD symptoms, three studies assessed full PTSD, and two studies assessed both. The pooled prevalence of PTSD symptoms was 42% (95% CI 30%-55%), and the pooled prevalence of a PTSD diagnosis was 30% (95% CI 21%-40%). Exploratory subgroup analyses suggest that prevalence may be higher in affective psychosis and inpatient samples. Evidence from included studies implicate depression and anxiety as potential risk factors for PTSD symptoms.

CONCLUSIONS

Approximately one in two people experience PTSD symptoms and one in three experience full PTSD following a first psychotic episode. Evidence-based interventions to treat PTSD symptoms in the context of FEP are needed to address this burden and improve outcomes after the first psychotic episode. Further studies are needed to clarify the associated risk factors.

Burnout in early course psychosis caregivers: the role of illness beliefs and coping styles

AIMS

In occupational settings, burnout is a common response to chronic exposure stressors and has been frequently documented in formal caregivers (i.e. paid psychiatric staff). However, the literature is limited on reports of burnout among informal caregivers and particularly within early psychosis groups. The current study sought to investigate reports of burnout in carers of young adults treated within a specialist early psychosis service and links with key appraisals reported about the illness and coping.

METHODS

Seventy-two carers completed the Maslach Burnout Inventory along with self-report measures of coping styles and illness beliefs.

RESULTS

Seventy-eight per cent of carers reported high burnout in at least one of the three key burnout markers (i.e. emotional exhaustion, depersonalization or low personal accomplishment). Seven per cent of carers met full criteria for high burnout across all the three domains. A carer's belief about the negative consequences of the illness for themselves was a significant predictor of emotional exhaustion and depersonalization. Low personal accomplishment was linked to a carer's less optimistic beliefs about the illness timeline and fewer reports of adaptive coping.

CONCLUSIONS

The results provide preliminary support for the importance of asking carers in the early illness phase about their experiences of caregiving. Targeted assessment may serve as a helpful tool to identify and intervene with carers in need of additional support with stress management, use of adaptive coping strategies, and balanced recovery focused information about psychosis.

Distress, Psychotic Symptom Exacerbation, and Relief in Reaction to Talking about Trauma in the Context of Beneficial Trauma Therapy: Perspectives from Young People with Post-Traumatic Stress Disorder and First Episode Psychosis

Background: Of young people with first episode psychosis (FEP), over half report exposure to childhood trauma and consequent co-morbid post-traumatic stress disorder (PTSD) or symptoms. Currently no evidence-based interventions exist for PTSD in FEP. Clinicians report concerns that trauma-focused interventions with young people with FEP could result in distress and symptom exacerbation. Scant research suggests that talking about trauma in therapy can be distressing for some people. Aims: To explore young people's reactions to a trauma-focused treatment for PTSD in FEP. Method: Semi-structured interviews were conducted with eight participants (age 18–27 years) with co-morbid PTSD and FEP, after completing a trauma-focused intervention. Transcripts were analysed using an interpretative phenomenological approach. Participants’ baseline and end-of-treatment PTSD and psychotic symptoms were assessed. Results: Three themes related to participants’ reactions were identified from the analysis: (1) distress in session; (2) feeling relieved in and out of session; and (3) symptom exacerbation out of session. All but one participant reported experiencing increased distress in session. Four participants described PTSD, psychotic symptoms and/or suicidal ideation worsening in immediate reaction to talking about trauma in therapy sessions. 86% of participants showed improvement in their PTSD and psychotic symptoms at end of treatment. All participants described the intervention as beneficial and worthwhile. Conclusions: Results suggest that feelings of distress are to be expected from individuals with PTSD and FEP during trauma-focused treatment. Psychotic and PTSD symptom exacerbation can occur in PTSD treatment in FEP. Clinicians should be aware of, plan for, and clearly inform their clients of treatment risks.

Posttraumatic Reactions to Psychosis: A Qualitative Analysis

The current study aimed to evaluate the potentially traumatic aspects of psychotic symptoms and psychiatric treatment of psychosis using qualitative methods. Participants included 63 people with first episode psychosis or multiple psychotic episodes recruited from an inpatient psychiatric unit and an urban state psychiatric hospital in the North East region of the United States. Quasi-structured interviews were used to explore those aspects of symptoms and treatment that were perceived as traumatic Emotional reactions to the most traumatic aspect of symptoms and treatment, during and after the event, were also examined. Participants described a number of traumatogenic aspects of psychotic symptoms, including frightening hallucinations; suicidal thought/attempts, thoughts/attempts to hurt others; paranoia/delusions and bizarre/disorganized behavior or catatonia. Traumatic aspects of psychosis elicited emotions including anger, sadness and confusion, anxiety, and numbness at the time of event. Furthermore, many participants found aspects of treatment to be traumatic, including: being forced to stay in the hospital for a long time; experiencing upsetting side-effects; coercive treatments, including involuntary hospitalization, use of restraints, and forced medication; being exposed to aggressive patients; and mistreatment by professionals. These experiences elicited emotions of anger, sadness, distrust, and a sense of helplessness. Study findings suggest that the experiences both of psychotic symptoms and psychiatric treatment, potentially traumatic, can be a powerful barrier to engaging people in mental health services and facilitating recovery. Clinical implications were discussed.

Childhood adversities: Social support, premorbid functioning and social outcome in first-episode psychosis and a matched case-control group

OBJECTIVE

The establishment of childhood adversities as risk factors for non-affective psychosis has derived a need to consider alternative interpretations of several psychosis-related factors. This paper sought to examine premorbid adjustment trajectories and social outcome factors in relation to childhood adversities. Perceived support has been found to decrease the risk of post-traumatic stress disorder, and we wished to compare perceived support in people with first-episode psychosis to non-clinical control persons and explore its relation to childhood adversities.

METHOD

Every individual presenting with a non-affective first-episode psychosis (F20-29, except F21) in Region Zealand over a 2-year period was approached for participation and the 101 consenting participants were matched to 101 people with no psychiatric disorders. Comprehensive demographic data were collected. Assessment instruments included the Premorbid Assessment Scale, the Global Assessment of Functioning scale and the Childhood Trauma Questionnaire. The latter represented the childhood adversities in addition to parental separation and institutionalization.

RESULTS

There were no associations between number of childhood adversities and different social or academic premorbid trajectories. Those with more adversities had lower global functioning the year prior to treatment start and reported lower rates of perceived support during childhood along with less current face-to-face contact with family members. Lack of peer support remained a significant predictor of psychosis when adversities were adjusted for; peer support diminished the risk of psychosis caused by childhood adversities by 10%.

CONCLUSION

Childhood adversities may not predict specific premorbid trajectories, but have an effect on global functioning when the psychosis has begun. Perceived support, especially from peers, may be important in the development of psychosis, and those with more adversities may represent a vulnerable subgroup who need more assistance to increase and maintain supportive networks.

The Experience of Childhood Trauma and Its Influence on the Course of Illness in First-Episode Psychosis: A Qualitative Study

Persons with schizophrenia spectrum disorders often report high levels of childhood trauma, which often exacerbates symptoms and impede the process of recovery. However, little is known about how these traumas are experienced by service users and how they are integrated in their life stories. To examine this, we conducted in-depth interviews with 15 service users with a diagnosis of a first-episode nonaffective psychosis who had reported 1 or more childhood traumas in self-report measures. There was an unexpected discrepancy between the number of traumas reported in self-report measures and in semistructured interviews, and many of the traumas did not seem integrated in their personal narratives. The analyses further revealed that although participants often described complicated and traumatic childhood environments, they still felt supported by their families; they reported a range of ways in which they tried to cope with and gain control of their psychotic disorder, and they described a general optimistic view of the future.

Narrowing the focus on the assessment of psychosis-related PTSD: a methodologically orientated systematic review

BACKGROUND

Posttraumatic stress disorder (PTSD) in response to psychosis and associated experiences (psychosis-related PTSD, or PR-PTSD) is the subject of a growing field of research. However, a wide range of PR-PTSD prevalence rates has been reported. This may be due to definitional and methodological inconsistencies in the assessment of PR-PTSD.

OBJECTIVE

The focus of the review is two-fold. (1) To identify factors that enhance, or detract from, the robustness of PR-PTSD assessment and (2) to critically evaluate the evidence in relation to these identified criteria, including the impact on PR-PTSD prevalence rates.

METHOD

Four quality criteria, whose development was informed by mainstream PTSD research, were selected to evaluate findings on PR-PTSD prevalence. Two criteria related to assessment of psychosis-related stressors (participant identification of worst moments of discrete threat events; psychometrically robust trauma measure) and two focussed on PR-PTSD symptom measurement (adequate time elapsed since trauma; use of validated PTSD interview) in the context of psychosis.

RESULTS

Twenty-one studies of PR-PTSD, with prevalence rates ranging from 11 to 51%, were evaluated. Fourteen studies (67%) used robust PTSD measures but PR-trauma was not specifically defined or assessed with validated measures. Eleven studies (52%) assessed PTSD before sufficient time had elapsed since the trauma. Due to significant methodological limitations, it was not possible to review PR-PTSD rates and provide a revised estimate of prevalence.

CONCLUSIONS

Methodological limitations are common in existing studies of PR-PTSD prevalence. Specific recommendations for improving assessment of psychosis-related trauma are made to guide the development of this new and emerging field. The review concludes with a proposed conceptualisation of PR-PTSD in the context of current diagnostic systems. The utility of the PR-PTSD term and its theoretical underpinnings are discussed.

The prevalence and correlates of childhood trauma in patients with early psychosis

OBJECTIVE

To describe the prevalence and demographic, clinical and functional correlates of childhood trauma in patients attending early psychosis clinics.

METHOD

Participants were recruited from outpatients attending four early psychosis services. Exposure to childhood trauma was assessed using the Childhood Trauma Questionnaire (CTQ). Psychopathology was measured using the Positive and Negative Syndrome Scale and the Depression, Anxiety and Stress Scale. Social and vocational functioning and substance use were also assessed.

RESULTS

Over three-quarters of the 100 patients reported exposure to any childhood trauma. Emotional, physical and sexual abuse were reported by 54%, 23% and 28% of patients, respectively, while 49% and 42% of patients reported emotional and physical neglect, respectively. Female participants were significantly more likely to be exposed to emotional and sexual abuse. Exposure to childhood trauma was correlated with positive psychotic symptoms and higher levels of depressive, anxiety and stress symptoms; however, it had no impact on social or vocational functioning or recent substance use.

CONCLUSION

Exposure to childhood trauma was common in patients with early psychosis, and associated with increased symptomatology. Existing recommendations that standard clinical assessment of patients with early psychosis should include inquiry into exposure to childhood trauma are supported.

Understanding the trauma of first-episode psychosis

AIM

This study examined the distress of first-episode psychosis (FEP) beyond the acute episode. It focused on how people understand the experience of FEP and its negative impact and how this relates to the traumagenic phenomena.

METHODS

This research was a longitudinal qualitative study including interpretative phenomenological analysis of interview data. Ten people who had experienced FEP were interviewed 3-6 months following their psychotic episode (time one) and again 3 months after their initial interview (time two). Clinicians and significant others were interviewed at time two.

RESULTS

Interpretative phenomenological analysis of the interview data supported a conceptualization of recovery from FEP within a broad trauma framework. The traumatic nature of FEP was found to be extended beyond the acute episode and was not linked to symptoms of post-traumatic stress disorder (PTSD) but included impact on identity, relationships and worldview.

CONCLUSIONS

The diagnosis of PTSD does not appear to capture all aspects of the distress of FEP. Traumagenic distress appears explained by incorporating a range of negative emotions, viewing the impact of FEP as ongoing rather than contained to the acute episode, and recognizes disruption of the individual's views of the self, others and the world.

Childhood Maltreatment and PTSD: Spiritual Well-Being and Intimate Partner Violence as Mediators

Childhood maltreatment places individuals, including African American women who are undereducated and economically disadvantaged, at risk for developing posttraumatic stress disorder (PTSD) symptoms. Participants were 192 African American women with a history in the prior year of both a suicide attempt and intimate partner violence (IPV) exposure. They were recruited from a public hospital that provides medical and mental health treatment to mostly low-income patients. A simple mediator model was used to examine if (1) existential well-being (sense of purpose) and/or religious well-being (relationship with God) mediated the link between childhood maltreatment and adult PTSD symptoms. Sequential multiple mediator models determined if physical and nonphysical IPV enhanced our understanding of the mediational association among the aforementioned variables. Findings suggest that existential well-being mediated the association between childhood maltreatment and adult PTSD symptoms in a simple mediator model, and existential well-being and recent nonphysical IPV served as sequential multiple mediators of this link. However, religious well-being and physical IPV were not significant mediators. Findings underscore the importance of enhancing existential well-being in the treatment of suicidal African American women with a history of childhood maltreatment and IPV.

Distinguishing schizophrenia from posttraumatic stress disorder with psychosis

PURPOSE OF REVIEW

Co-occurrence of psychotic symptoms with symptoms typically thought of as posttraumatic stress disorder (PTSD) is well known, and there has been considerable debate whether this represents a psychotic subtype or a comorbid psychotic disorder.

RECENT FINDINGS

Psychotic symptoms typical of schizophrenia occur with a higher than expected frequency in PTSD. A large genome-wide association study (GWAS) has identified a collection of genes associated with PTSD, and these genes overlap with those identified as increasing the risk of developing schizophrenia.

SUMMARY

Up to 70% of returning veterans experience symptoms of PTSD. These individuals also fall within the peak age range for the onset of schizophrenia. PTSD with psychosis may occur for several reasons: trauma increases one's risk for schizophrenia and PTSD; patients with schizophrenia have a higher incidence of PTSD and may present with characteristic psychotic symptoms overlapping with psychosis in schizophrenia. Secondary to symptom overlap, there may be substantial misdiagnosis of psychotic disorders as PTSD, or nonidentification of a comorbid psychotic disorder. This overlap calls into question traditional diagnostic boundaries with implications for initial and long-term treatment of PTSD and psychosis. This review will discuss the recent literature relating to the association of PTSD with schizophrenia.

Perceptions of clinicians treating young people with first-episode psychosis for post-traumatic stress disorder

AIM

Evidence shows that approximately half of young people with first-episode psychosis have post-traumatic stress disorder. Yet, post-traumatic stress disorder is often left untreated in the presence of psychosis. To support the development of a post-traumatic stress disorder intervention for young people with first-episode psychosis, clinicians' perceptions of trauma-focused interventions were sought. Two research questions were explored: What treatment barriers were associated with treating young people with first-episode psychosis? What supports would be useful to implement post-traumatic stress disorder intervention?

METHODS

A mixed-methods design incorporated quantitative and qualitative data from a questionnaire with qualitative data from two focus groups. Sixteen (of 20) case managers from an early psychosis intervention centre participated in the study (16 completed a questionnaire, eight participated in focus groups). Descriptive statistics were generated for quantitative data and qualitative material was examined using a grounded theory approach.

RESULTS

The results showed that perceived barriers to delivering trauma-focused intervention were increased mental health risks for clients with psychosis, workload pressures and poor client engagement. Targeted training and formal professional guidance were thought to best scaffold an intervention.

CONCLUSIONS

Post-traumatic stress disorder intervention for first-episode psychosis clients should address engagement, make safeguarded provisions for family involvement and be sufficiently paced and flexible. Trauma-focused intervention is perceived with a degree of caution, is often not prioritized, lacks institutional support and requires more targeted training. It is important to conduct further research regarding the safety of trauma interventions alongside psychosis in order to address widespread concerns.

Measuring trauma and stressful events in childhood and adolescence among patients with first-episode psychosis: initial factor structure, reliability, and validity of the Trauma Experiences Checklist

Past trauma and stressful events, especially in childhood and adolescence, are common among individuals with serious mental illnesses like schizophrenia. Traumatic experiences are thought to be a socio-environmental risk factor not only for poorer outcomes, but also potentially for the onset of these disorders. Because improved measurement tools are needed, we developed and studied, among 205 first-episode psychosis patients, the factor structure, internal consistency reliability, and initial validity of the Trauma Experiences Checklist (TEC), our measure of trauma and stressful events during childhood/adolescence. We assessed validity of subscales using correlations with Childhood Trauma Questionnaire-Short Form, Parental Harsh Discipline, Violence Exposure, and TEC-Informant Version scores. Exploratory factor analysis resulted in two internally consistent subscales (Cronbach's α=0.79 and 0.80, respectively), interpersonal abuse and family stress, and violence, death, and legal involvement. Scores from the former subscale were substantially associated with CTQ-SF physical, emotional, and sexual abuse (r=0.42-0.57, all p<0.001) and Violence Exposure (r=0.49, p<0.001). On the other hand, violence, death, and legal involvement scores were most highly correlated with Violence Exposure (r=0.49, p<0.001), and not with most CTQ-SF subscales. The TEC is a potentially useful tool in assessing diverse traumatic life events across various social contexts during childhood and adolescence.

Testing a model of the relationship between childhood sexual abuse and psychosis in a first-episode psychosis group: the role of hallucinations and delusions, posttraumatic intrusions, and selective attention

Several theories suggest that posttraumatic intrusive symptoms are central to the relationship between childhood trauma (CT) and hallucinations and delusions in psychosis. Biased selective attention has been implicated as a cognitive process underlying posttraumatic intrusions. The current study sought to test theories of the relationship between childhood sexual abuse (CSA), hallucinations and delusions, posttraumatic intrusions, and selective attention in first-episode psychosis (FEP). Twenty-eight people with FEP and 21 nonclinical controls were assessed for CT and psychotic and posttraumatic stress symptoms and completed an emotional Stroop test using CSA-related and other words. Those with FEP and CSA had more severe hallucinations and delusions than those with FEP and without CSA. They also reported posttraumatic intrusions at clinical levels and showed selective attention to CSA-related words. The results are consistent with the posttraumatic intrusions account of hallucinations and delusions in those with CSA and psychosis.

Enhanced cortisol suppression following administration of low-dose dexamethasone in first-episode psychosis patients

OBJECTIVE

Impaired regulation of the hypothalamic-pituitary-adrenal (HPA) axis and hyper-activity of this system have been described in patients with psychosis. Conversely, some psychiatric disorders such as post-traumatic stress disorder (PTSD) are characterised by HPA hypo-activity, which could be related to prior exposure to trauma. This study examined the cortisol response to the administration of low-dose dexamethasone in first-episode psychosis (FEP) patients and its relationship to childhood trauma.

METHOD

The low-dose (0.25 mg) Dexamethasone Suppression Test (DST) was performed in 21 neuroleptic-naïve or minimally treated FEP patients and 20 healthy control participants. Childhood traumatic events were assessed in all participants using the Childhood Trauma Questionnaire (CTQ) and psychiatric symptoms were assessed in patients using standard rating scales.

RESULTS

FEP patients reported significantly higher rates of childhood trauma compared to controls (p = 0.001) and exhibited lower basal (a.m.) cortisol (p = 0.04) and an increased rate of cortisol hyper-suppression following dexamethasone administration compared to controls (33% (7/21) vs 5% (1/20), respectively; p = 0.04). There were no significant group differences in mean cortisol decline or percent cortisol suppression following the 0.25 mg DST. This study shows for the first time that a subset of patients experiencing their first episode of psychosis display enhanced cortisol suppression.

CONCLUSIONS

These findings suggest there may be distinct profiles of HPA axis dysfunction in psychosis which should be further explored.
