Unravelling the contribution of complex trauma to psychopathology and cognitive deficits: a cohort study

Patterns of Adverse Childhood Experiences and Neurocognitive Development

Importance

Early life adversity is associated with higher risk of many adult health problems, including mental illness, substance abuse, suicide attempt, and chronic diseases. Many previous studies investigated adversities one at a time or investigated the health toll associated with the cumulative number of adversities.

Objective

To examine the co-occurrence of adversities among children and how specific patterns of adversities are associated with neurocognitive development.

Design, Setting, and Participants

This cohort study used data from the Collaborative Perinatal Project (CPP), which enrolled a national sample of women during pregnancy and followed their offspring to ages 7 to 8 years, between 1959 and 1974. The CPP was a community-based study conducted in 12 US medical centers. The CPP sample was ascertained through prenatal clinics and is diverse with respect to race and socioeconomic status. Data analysis was performed from August 2023 to March 2024.

Exposures

A latent class analysis was conducted of 12 adverse childhood experiences that occurred between birth and 7 years to identify common patterns of childhood adversities.

Main Outcomes and Measures

Five neurocognitive tests were used to measure children's visual-motor, sensory-motor, auditory-vocal, intelligence quotient, and academic skills.

Results

The analysis sample included 49 853 offspring (25 226 boys [50.6%]); 24 436 children (49.0%) had low probability of experiencing any adversity, whereas the remaining half were classified into 5 groups reflecting distinct patterns of childhood adversities: parental harshness and neglect, 1625 children (3.3%); parental separation and poverty, 8731 children (17.5%); family instability, 3655 children (7.3%); family loss, instability, and poverty, 1505 children (3.0%); and crowded housing and poverty, 9901 children (19.9%). Children in 4 of these groups had lower neurocognitive scores than children with a low probability of experiencing adversity, with standardized mean differences ranging from -0.07 (95% CI, -0.11 to -0.03) to -0.86 (95% CI, -1.06 to -0.65).

Conclusions and Relevance

These findings suggest that adverse childhood experiences are associated with deficits in children's neurocognitive functions. It is important to understand the complexity in children's exposure to adversity and the resulting developmental consequences, as well as the underlying mechanisms, to help support children exposed to adversity and foster healthier and resilient trajectories of development.

Temporal-Posterior Alpha Power in Resting-State Electroencephalography as a Potential Marker of Complex Childhood Trauma in Institutionalized Adolescents

The present study explored whether, given the association of temporal alpha with fear circuitry (learning and conditioning), exposure to complex childhood trauma (CCT) is reflected in the temporal-posterior alpha power in resting-state electroencephalography (EEG) in complex trauma-exposed adolescents in a sample of 25 adolescents and similar controls aged 12-17 years. Both trauma and psychopathology were screened or assessed, and resting-state EEG was recorded following a preregistered protocol for data collection. Temporal-posterior alpha power, corresponding to the T5 and T6 electrode locations (international 10-20 system), was extracted from resting-state EEG in both eyes-open and eyes-closed conditions. We found that in the eyes-open condition, temporal-posterior alpha was significantly lower in adolescents exposed to CCT relative to healthy controls, suggesting that childhood trauma exposure may have a measurable impact on alpha oscillatory patterns. Our study highlights the importance of considering potential neural markers, such as temporal-posterior alpha power, to understanding the long-term consequences of CCT exposure in developmental samples, with possible important clinical implications in guiding neuroregulation interventions.

Modifiable factors associated with cognitive performance in Chinese adolescents: a national environment-wide association study

Growing evidence exists about the candidate factors of childhood cognitive performance, but mainly limited to single-exposure studies. We sought to systematically and simultaneously identify and validate a wide range of potential modifiable factors for childhood cognitive performance. We used data from five waves of data from the China Family Panel Studies (CFPS-2010, 2012, 2014, 2016 and 2018). Our analytical sample was restricted to those children aged 2-5 at baseline with valid exposure information. A total of 80 modifiable factors were identified. Childhood cognitive performance was assessed using vocabulary and mathematics test at wave 5. We used an environment-wide association study (EnWAS) to screen all exposure-outcome associations independently and used the least absolute shrinkage and selection operator (LASSO) variable selection algorithm to identify factors associated with cognitive performance. Multivariable linear model was then used to evaluate causal relationships between identified factors and cognitive performance. Of the 1305 participants included in the study (mean ± SD, 3.5 ± 1.1 years age at baseline, 45.1% girls). Eight factors were retained in the LASSO regression analysis. Six factors across community characteristics (percentage of poverty in the community; percentage of children in the community), household characteristics (family size), child health and behaviors (mobile internet access), parenting behaviors and cognitive enrichment (parental involvement in child' s education), and parental wellbeing (paternal happiness) domains were significantly associated with childhood cognition. Using a three-stage approach, this study validates several actionable targets for improving childhood cognitive performance.

Neural differentiation of emotional faces as a function of interpersonal violence among adolescent girls

Interpersonal violence (IV) is associated with altered neural threat processing and risk for psychiatric disorder. Representational similarity analysis (RSA) is a multivariate approach examining the extent to which differences between stimuli correspond to differences in multivoxel activation patterns to these stimuli within each ROI. Using RSA, we examine overlap in neural patterns between threat and neutral faces in youth with IV. Participants were female adolescents aged 11-17 who had a history of IV exposure (n = 77) or no history of IV, psychiatric diagnoses, nor psychiatric medications (n = 37). Participants completed a facial emotion processing task during fMRI. Linear mixed models indicated that increasing hippocampal differentiation of fear and neutral faces was associated with increasing IV severity. Increased neural differentiation of these facial stimuli in the left and right hippocampus was associated with increasing physical abuse severity. Increased differentiation by the dACC correlated with increasing physical assault severity. RSA for most ROIs were not significantly associated with univariate activity, except for a positive association between amygdala RSA and activity to fear faces. Differences in statistically significant ROIs for physical assault and physical abuse may highlight distinct effects of trauma type on encoding of threat vs. neutral faces. Null associations between RSA and univariate activation in most ROIs suggest unique contributions of RSA for understanding IV compared to traditional activation. Implications include understanding mechanisms of risk in IV and trauma-specific treatment selection. Future work should replicate these findings in longitudinal studies and identify sensitive periods for neural alterations in RSA.

Partner Effects of Childhood Maltreatment: A Systematic Review and Meta-Analysis

Although several studies have shown that childhood maltreatment (CM) is associated with a host of negative consequences including romantic relationship difficulties for victims in adulthood, most overlooked the potential effects on the romantic partner. This systematic review and meta-analysis aims to comprehensively synthesize the literature on the association between a person's CM and their partner's individual and couple outcomes. We searched PubMed, PsycNET, Medline, CINAHL, and Eric using search strings related to CM and partner. We identified 3,238 articles after removal of duplicates; 28 studies met the inclusion criteria and relied on independent sample. The studies reported associations between a person's CM and a wide breadth of partner's negative couple outcomes (e.g., communication, sexuality) as well as intra-individual psychological difficulties (e.g., psychological distress, emotion, and stress reactivity). Meta-analytic results showed significant, but trivial to small associations between a person's CM and their partner's lower relationship satisfaction (r = -.09, 95% CI [-.14, -.04]), higher intimate partner violence (r = .08, [.05, .12]), and higher psychological distress (r = .11, [.06, .16]). These associations were similar for women and men and did not differ as a function of sample's mean age, proportion of cultural diversity, and publication year. These findings suggest that a person's CM is related to their partner's outcomes including to the partner's intra-individual outcomes. Prevention and intervention strategies should acknowledge that a person's CM may also affect their romantic partner, considering the couple as a reciprocal system, and offer victims' romantic partners specific services.

Associations Between Distinct Trauma Classes and Mental Health Care Utilization in Norwegian Adolescents: A National Registry Study

Adolescents who experience potentially traumatic experiences (PTEs) have an increased risk of psychopathology. PTEs often co-occur and may form interrelated patterns of exposure. This study investigated underlying classes of PTE exposure among Norwegian adolescent participants in the youth@hordaland study, and whether such classes were associated with contact with child and adolescent mental health services (CAMHS) and psychiatric diagnoses. The data stem from the population-based youth@hordaland study conducted in 2012 which was linked to the Norwegian Patient Registry (NPR, n = 8845). Exposure to PTEs was assessed by adolescent self-report whereas psychiatric disorders (Axis 1) were derived from the NPR. Latent Class Analysis was used to identify distinct classes of PTE exposure-patterns in the data. Logistic regression analyses were performed to investigate associations between classes of PTEs and contact with CAMHS and psychiatric diagnoses. Three classes of PTE exposure were identified based on model fit indices and theoretical considerations. Compared with participants in the low trauma class (88% of participants), those in the Situational-(6%) and Interpersonal trauma class (6%) had higher odds-ratios (ORs) for contact with CAMHS (OR = 2.27 (95% CI [1.78, 2.87])) and (OR = 3.26 (95% CI [2.61, 4.04])) respectively, and for being diagnosed with a psychiatric disorder in CAMHS (ORs ranged from 2.19 - 10.4) after adjusting for sex and parental education. There were more participants diagnosed with ADHD within the Interpersonal trauma class compared to the Situational trauma class when adjusting for sex and parental education (OR = 2.22 (95% CI [1.17, 4.40])). Three relatively homogeneous PTE classes, consisting of distinct patterns of trauma exposure were associated with a higher odds of contact with CAMHS and of being diagnosed with a psychiatric disorder in CAMHS. The study highlights the co-occurrence of PTEs and their impact across the diagnostic spectrum.

The Impact of Complex Trauma on Occupations and Daily Functioning in Childhood: A Scoping Review

AIMS

To explore the impact of complex trauma on occupations and daily functioning in childhood through empirical studies and asses the extent and state of available evidence.

METHODS

The five-stage scoping review framework by Arksey and O'Malley and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR: Tricco et al.) were followed. EMBASE, MEDLINE, CINAHL, PsychINFO, and Web of Science databases were systematically searched. Included studies were empirical research published in English up to December 2022, reporting on the impact of complex trauma on daily functioning or occupations in children experiencing such trauma, defined as prolonged exposure to interpersonal trauma arising within the primary caregiving system.

RESULTS

Eight studies were included. They reported impacts on personal and instrumental activities of daily living, sleep, education, work, play, leisure, and social participation. Some domains lacked comprehensive investigation, and studies lacked descriptions of specific effects on these areas.

CONCLUSIONS

The review reveals a lack of robust empirical evidence on the impact of complex trauma on occupations and daily functioning in childhood, with limited depth for comprehensive analysis on the extent of children's occupational life impact. Further research is warranted to address identified gaps.

Prevalence of co-occurring severe depression and psychotic symptoms in college students and its relationship with childhood maltreatment

BACKGROUND

It has been demonstrated that childhood maltreatment (CM) is associated with an increased risk of depression and psychotic symptoms. However, there is still a lack of studies on the prevalence of co-occurring severe depression and psychotic symptoms (CSDPS) and the association between CM and CSDPS among college students.

OBJECTIVE

We aim to investigate the prevalence and demographic distribution of CSDPS among Chinese college students and to examine its relationship with CM.

PARTICIPANTS AND SETTING

A total of 7351 college students aged 18 and above completed the survey. Finally, 6854 valid questionnaires were included for further analysis.

METHODS

The Childhood Trauma Questionnaire and the item for witnessing domestic violence were used to assess the CM. The Prodromal Questionnaire-16 and the depression subscale of the Depression Anxiety and Stress-21 scale were used to assess psychotic symptoms and depressive symptoms.

RESULTS

The prevalence of CSDPS was 1.47 % among the college students. The multivariate logistic regression analysis showed that emotional abuse and emotional neglect were associated with an increased risk of CSDPS (all p < 0.05). The risk of CSDPS was dramatically increased for individuals who had experienced ≥3 types of CM (OR = 22.929, p < 0.001), as compared to those who had experienced 1-2 types of CM (OR = 4.452, p < 0.001) and those without the experience of CM.

CONCLUSION

CM was found to be associated with an increased risk of CSDPS among the college students. Notably, experiencing more types of CM was also associated with a higher risk of CSDPS.

Childhood maltreatment and mental health problems in a 10-year follow-up study of adolescents in youth residential care: A latent transition analysis

Childhood maltreatment and mental health problems are common among young people placed out-of-home. However, evidence on the impact of maltreatment on the course of mental health problems in at-risk populations is sparse. The aim of this longitudinal study is twofold: (a) describe the course of mental health problems and the shift in symptom patterns among adolescents in youth residential care into young adulthood and (b) assess how childhood maltreatment is related to the course of mental health problems. One hundred and sixty-six adolescents in Swiss youth residential care were followed up into young adulthood (36.1% women; MAge-Baseline = 16.1 years; MAge-Follow-Up = 26.4 years). Latent transition analysis was employed to analyze transitions of symptom patterns and their association with maltreatment exposure. We found three latent classes of mental health problems: a "multiproblem"-class (51.8% baseline; 33.7% follow-up), a "low symptom"-class (39.2% baseline; 60.2% follow-up), and an "externalizing"-class (9.0% baseline; 6.0% follow-up). Individuals in the "multiproblem"-class were likely to transition towards less-complex symptom patterns. Higher severity of self-reported childhood maltreatment was associated with more complex and persistent mental health problems. Our study underlines the need for collaboration between residential and psychiatric care systems within and after care placements, with a specialized focus on trauma-informed interventions and care.

Editorial: Are Group-Based Interventions Effective for Treating Trauma-Related Psychopathology in Children and Young People?

Trauma-exposed young people are about twice as likely as their unexposed peers to develop mental health problems, which, if left untreated, can have long-term negative consequences.1 There is robust evidence for the effectiveness of individual trauma-focused psychological therapies to improve trauma-related psychopathology, particularly posttraumatic stress disorder (PTSD), in young people.2 However, there are minimal services that provide such specialist treatments in low/middle-income countries where most young people live,3 and services may be severely disrupted at times of extreme stressors, such as war, natural disasters, and other humanitarian crises, when need is greatest.4 Moreover, even in high-income stable regions where child mental health services are established and treatments are available, these health care resources are limited, and can only be accessed by a minority of affected trauma-exposed young people.5 There is therefore a need for research to indicate effective interventions that are more accessible and can be delivered on a greater scale to treat more young people with trauma-related psychopathology.6 The recent meta-analysis by Davis et al.7 focused on the more accessible intervention of group-based psychological treatment for child PTSD symptoms, and found evidence of effectiveness compared with control conditions. The study provides an important advancement in this field, and also highlights the need for further research to better understand how group interventions can be most usefully implemented.

Focusing the Clinical Supervision on the Therapist's Developmental Trauma: A Single Case Study

The term developmental trauma (DT) refers to the impact of stressful events which occur cumulatively within the child's relevant relationships and contexts, and usually early in life. According to several authors, DT depends on the caregiver's inadequate intersubjective recognition of one or more aspects of the evolving individual's identity. In the clinical and empirical literature, the study of therapists' developmental trauma, and how it might constitute a relevant variable in the clinical exchange, seem to be underrepresented. In this paper, through the analysis of the supervision process of a clinical case, we show how the therapeutic relationship may implicitly take the form of a "dance" between the patient's and therapist's DT, that prevents the therapist from intersubjectively attuning with the patient; and how a supervision process peculiarly focused on the therapist's DT can effectively promote this attunement and a good clinical outcome.

Roadmap for Trauma-Informed Medical Education: Introducing an Essential Competency Set

Research has established that trauma is nearly universal and a root cause of numerous health and social problems, including 6 of the 10 leading causes of death, with devastating consequences across the life course. Scientific evidence now recognizes the complex injurious nature of structural and historical trauma (i.e., racism, discrimination, sexism, poverty, and community violence). Meanwhile, many physicians and trainees grapple with their own trauma histories and face direct and secondary traumatization on the job. These findings substantiate the profound impact of trauma on the brain and body and why trauma training is critical to the education and practice of physicians. However, a critical lag remains in translating essential research insights into clinical teaching and care. Recognizing this gap, the National Collaborative on Trauma-Informed Health Care Education and Research (TIHCER) formed a task force charged with developing and validating a summary of core trauma-related knowledge and skills for physicians. In 2022, TIHCER released the first-ever validated set of trauma-informed care competencies for undergraduate medical education. The task force focused on undergraduate medical education so that all physicians would be taught these foundational concepts and skills from the outset of training, recognizing that faculty development is needed to achieve this goal. In this Scholarly Perspective, the authors offer a roadmap for implementation of trauma-informed care competencies starting with medical school leadership, a faculty-student advisory committee, and sample resources. Medical schools can use the trauma-informed care competencies as a scaffold to customize integration of curricular content (what is taught) and efforts to transform the learning and clinical environments (how it is taught). Using the lens of trauma will ground undergraduate medical training in the latest science about the pathophysiology of disease and provide a framework to address many of our greatest challenges, including health disparities and professional burnout.

Association of childhood trauma with cognitive domains in adult patients with mental disorders and in non-clinical populations: a systematic review

Although the association between cognitive performances and the onset of psychiatric disorders has been widely investigated, limited research on the role of childhood trauma or early life stress (CT/ELS), and whether this role differs between clinical and non-clinical cohorts is available. This systematic review aims at filling this gap, testing whether the occurrence of CT/ELS and its subtypes are associated with cognitive domains (general cognitive ability, executive functions, working memory, attention, processing speed, verbal/visual memory) in patients with psychiatric disorders and in non-clinical populations. This study followed the PRISMA 2020 guidelines and the Newcastle-Ottawa scale for quality assessment. The search was performed until May 2022. Seventy-four studies were classified as eligible. The graphical representations of the results reported an association between exposure to CT/ELS and worse general cognitive ability, verbal/visual memory, processing speed and attention in patients affected by anxiety, mood and psychotic disorders, and that specific CT/ELS subtypes (physical neglect, physical/sexual abuse) can differentially influence specific cognitive abilities (executive functions, attention, working memory, verbal/visual memory). In non-clinical cohorts we found associations between CT/ELS exposure and impairments in executive functions, processing speed and working memory, while physical neglect was related to general cognitive ability and working memory. Concerning the emotional abuse/neglect subtypes in both populations, the results indicated their involvement in cognitive functioning; however, the few studies conducted are not enough to reach definitive conclusions. These findings suggest an association of CT/ELS with specific cognitive deficits and psychopathology.

Something old, something new - can adding genomic data to family studies advance our understanding of the impact of nature and nurture on mental health? Commentary on McAdams et al. (2023)

In their annual research review, McAdams, Cheesman, and Ahmadzadeh (2023) provide a thorough overview of how the use of novel genetically informative approaches can increase our knowledge about the intergenerational transmission of psychopathology. Many JCPP readers will already be familiar with genetically sensitive family-based designs, such as twin and adoption studies, as well as with newer molecular-genetic approaches, such as polygenic-score studies. McAdams et al.'s (2023) review discusses the innovative combination of family-based and molecular-genetic methods, and what this combination can reveal about developmental psychopathology.

A Longitudinal Investigation of the Relationship Between Trauma-Related Cognitive Processes and Internalising and Externalising Psychopathology in Young People in Out-of-Home Care

Young people in out-of-home care are at increased risk of developing a range of posttrauma mental health difficulties, including PTSD, but more commonly anxiety, depression and externalising symptoms. Cognitive models of PTSD indicate that trauma-related maladaptive appraisals, coping strategies and trauma memory qualities are key processes in the development and maintenance of PTSD, yet there has been limited investigation of the potential role of these processes in broader posttrauma psychopathology, particularly in young people who have been exposed to complex, rather than acute, trauma. We recruited 120 10-18 years olds in out-of-home care, and their caregivers, who completed assessments at two time points: baseline and 12-month follow-up. Young people completed self-report measures of trauma-related maladaptive appraisals, coping strategies and trauma-memory qualities, as well as reporting on PTSD, anxiety, depression and externalising symptoms. Carers also reported on internalising and externalising symptoms. We found that all three cognitive processes were associated with baseline self-reported internalising symptoms, with maladaptive appraisals most robustly associated with both anxiety and depression. Changes in all three processes over 12-months predicted a change in self-reported internalising and externalising symptoms, with maladaptive appraisals and coping predicting anxiety symptoms, and coping uniquely predicting depression and externalising symptoms. Effects remained after controlling for co-occurring PTSD symptoms. Findings were not replicated when using carer-reported symptoms. These findings suggest that existing cognitive models of PTSD may also usefully explain broader posttrauma depression, anxiety and externalising symptoms in young people who have experienced maltreatment and live in out-of-home care. Clinical implications are discussed.

Editorial: Measuring and Buffering the Mental Health Impact of the War in Ukraine in Young People

The Russian invasion of Ukraine on February 24, 2022, has caused social, political, and financial instability worldwide. In Ukraine, the war has brought the greatest levels of violence, devastation, and disruption seen in Europe since World War II. Of course, the impact of war on the mental health of Ukrainian young people is likely substantial. Yet, more specific information about the prevalence and distribution of mental health disorders in young people is essential to document their needs, to select the best interventions, and to deliver these through international humanitarian efforts. The study by Osokina and Silwal et al.¹ presents some of the best evidence to date about the mental health impact of the war in Ukraine on young people.

Outcomes of Parent-Child Interaction Therapy (PCIT) for families presenting with child maltreatment: A systematic review

BACKGROUND

The developmental consequences of childhood trauma for young children are extensive and impact a diverse range of areas. Young children require treatments that consider their developmental stage and are inclusive of caregiver involvement. Parent-Child Interaction Therapy (PCIT), with its dyadic focus and developmental sensitivity, is uniquely positioned to offer therapeutic support to young children and their families.

AIM

The current study aimed to conduct a systematic review of the current literature on PCIT and trauma and determine treatment outcomes for children and caregivers.

METHOD

A systematic review of five electronic databases was undertaken. Studies that utilized PCIT to treat a population who had experienced trauma were included in the review regardless of study design.

RESULTS

PCIT was used to treat a population who had experienced trauma in 40 studies. PCIT was an effective treatment in improving a variety of child and parent outcomes in this population including reduced parenting stress, child behavior problems, child trauma symptoms, parental mental health concerns, negative parenting strategies, and reducing potential risk of recidivism of abuse and neglect. These findings should be taken with caution given attrition rates and potential for bias in the study samples.

DISCUSSION

Clinicians should consider PCIT as a potential treatment for children who have experienced trauma and their families. Future research should incorporate corroborative sources of information, assessment of caregiver and child trauma symptoms, examination of permanency outcomes, and consider standardization of PCIT modifications for child trauma to determine treatment in this population of children.

Assessing autism spectrum disorder in children with a background of maltreatment: challenges and guidance

There may be some similarities in the presentation of children who have autism spectrum disorder (ASD) and those exposed to maltreatment affecting assessment and diagnosis. Overlapping characteristics include difficulties understanding and maintaining relationships, sensitivity to routine and hyper-reactivity to sensory inputs. Children who have been maltreated are at increased risk of various developmental vulnerabilities with both environmental and genetic factors being relevant. The existing epidemiological evidence has found that looked-after children are more likely to screen positively for neurodevelopmental disorders and there are smaller scale studies in adoptive children finding higher rates of ASD than would be expected in the general population. Other research suggests a predominantly genetic basis for this increased risk in keeping with what is generally understood about the aetiology of autism. Children exposed to profound deprivation in Romanian orphanages were found to be at higher risk of a pattern of traits termed 'quasi autistic' which tended to reduce following adoption, but these findings have not been replicated in children experiencing maltreatment in birth families. Reactive attachment disorder (RAD) has some overlapping criteria with ASD, but its prevalence is unknown and children with RAD should be more socially reciprocal and not have the same repetitive and restricted behaviours and interests. We recommend experienced multidisciplinary assessment that considers both the possibility of maltreatment in children with ASD and neurodevelopmental vulnerabilities in children who have been maltreated and advise on assessment and management strategies.

Complex Racial Trauma: Evidence, Theory, Assessment, and Treatment

Racial trauma refers to experiences related to threats, prejudices, harm, shame, humiliation, and guilt associated with various types of racial discrimination, either for direct victims or witnesses. In North American, European, and colonial zeitgeist societies, Black, Indigenous, and people of color (BIPOC) experience racial microaggressions and interpersonal, institutional, and systemic racism on a repetitive, constant, inevitable, and cumulative basis. Although complex trauma differs from racial trauma in its origin, the consistency of racist victimization beyond childhood, and the internalized racism associated with it, strong similarities exist. Similar to complex trauma, racial trauma surrounds the victims’ life course and engenders consequences on their physical and mental health, behavior, cognition, relationships with others, self-concept, and social and economic life. There is no way to identify racial trauma other than through a life-course approach that captures the complex nature of individual, collective, historical, and intergenerational experiences of racism experienced by BIPOC communities in Western society. This article presents evidence for complex racial trauma (CoRT), a theoretical framework of CoRT, and guidelines for its assessment and treatment. Avenues for future research, intervention, and training are also presented.

Associations Between Complex Trauma Exposure in Childhood/Adolescence and Psychopathology in Older Age: The Role of Stress Coping and Coping Self-Perception

Complex trauma exposure in childhood and/or adolescence is common and has repeatedly been linked to mental ill-health across the lifespan. While the correlates of complex trauma and mental health are well-studied in individuals up to middle adulthood, correlates in older adulthood, as well as potential mediators of this relationship, such as stress coping, are insufficiently studied. Therefore, this study aimed to (a) examine the mental health of Swiss older adults affected by complex trauma exposure in childhood and/or adolescence, in comparison to non-affected individuals; and (b) to examine the potential mediating role of coping strategies and coping self-perception. Data from N = 257 participants (complex trauma [CT] group: n = 161; M _age = 69.66 years, 48.4% female; non-complex trauma [nCT] group: n = 96; M _age = 72.49 years, 42.7% female) were assessed using self-report questionnaires and a clinical interview. The CT group presented with significantly more current and lifetime mental health disorders, more disadvantageous coping strategies, and significantly lower coping self-perception, compared to the nCT group. Mediation analyses revealed that maladaptive coping and coping self-perception were relevant mediators of the relationship between complex trauma exposure and psychopathology. Results suggest that complex trauma exposure in childhood and/or adolescence can have a lasting impact on mental health in later life and can be negatively associated with stress coping. Findings emphasize the relevance of a lifespan perspective in research and clinical practice for addressing consequences of complex trauma exposure.

Child Maltreatment and Couples' Sexual Health: A Systematic Review

INTRODUCTION

Childhood maltreatment (CM) is an interpersonal trauma reported by 35% to 40% of individuals in population-based studies in North America. It refers to physical, sexual, and emotional abuse, as well as physical and emotional neglect. Although there is a growing body of cross-sectional work focusing on associations between CM and sexual health, most studies have ignored the broader relationship context in which sexuality is experienced.

OBJECTIVES

The current review sought to systematically and critically appraise all studies that reported on the association between CM and couples' sexual health, to inform clinical care and recommendations for research.

METHODS

The electronic literature search was conducted using PubMed, PsycNET (PsycINFO, PsychArticles), Medline, CINAHL, and Eric for peer-reviewed journal articles published before September 2021. Eligible studies had to report on the association between any form of CM and any dimension of sexual health in couples or individuals in a romantic relationship.

RESULTS

In total, 13 studies (18 articles) were included in this systematic review: 4 studies pertained to clinical couples and 9, to community couples; 2 studies used a longitudinal design and 11, a cross-sectional design; 3 studies examined CM as a whole, 2 studies examined multiple subtypes of CM separately, 1 study examined both CM as a whole and its subtypes separately, whereas the other 7 studies focused on childhood sexual abuse. Results indicated that studies using valid measures of sexual health outcomes found significant associations between CM and worse outcomes - including declines over time - in both clinical and community samples. Mediators and moderators of these associations were also identified.

CONCLUSIONS

Findings provide preliminary support for the role of CM in couples' sexual health. There is a need for future longitudinal studies involving both members of the couple, valid and multidimensional measures of sexual health, and potential mediators and moderators.

Developmental trauma: Conceptual framework, associated risks and comorbidities, and evaluation and treatment

Children exposed to adverse childhood experiences (ACEs) and pervasive interpersonal traumas may go on to develop PTSD and, in most cases, will further undergo a significant shift in their developmental trajectory. This paper examines contemporary research on Developmental Trauma (DT), which is inextricably linked to disruptions in social cognition, physiological and behavioral regulation, and parent-child attachments. Developmental trauma associated with early experiences of abuse or neglect leads to multi-faceted and longstanding consequences and underscores critical periods of development, complex stress-mediated adaptations, and multilevel, trans-theoretical influences in the diagnostic formulation and treatment of traumatized children, adolescents, and adults. Psychological and medical correlates of Developmental Trauma Disorder are considered, and directions for future research are discussed.

Internalizing Mental Health Disorders and Emotion Regulation: A Comparative and Mediational Study of Older Adults With and Without a History of Complex Trauma Exposure

Individuals with complex trauma exposure (CTE) in early life (i.e., childhood/adolescence) are at heightened risk for developing problems in various domains of functioning. As such, CTE has repeatedly been linked to internalizing mental health disorders, such as depression and anxiety, as well as emotion dysregulation across the lifespan. While these correlates of CTE are comparatively well studied up to middle adulthood, they are insufficiently studied in older adulthood. Therefore, this study aimed to (a) compare Swiss older adults with and without a CTE history regarding current and lifetime internalizing mental health disorders and emotion regulation strategies; and (b) to examine the potential mediating role of emotion regulation in the mental health disparities between these groups. A total of N = 257 participants (age = 49-95 years; 46.3% female) were assessed in a retrospective, cross-sectional study, using two face-to-face interviews. The CTE group (n = 161; M age = 69.66 years, 48.4% female) presented with significantly more current and lifetime internalizing mental health disorders than the non-affected (nCTE) group (n = 96; M age = 72.49 years, 42.7% female). The CTE group showed significantly higher emotion suppression and lower emotion reappraisal compared to the nCTE group. Mediation analysis revealed that the two emotion regulation strategies were significant mediators between CTE history and internalizing mental health disorders. Findings emphasize the relevance of emotion (dys-)regulation in understanding mental health disparities in older age and deciding about treatment strategies. Research and practice should pay more attention to the needs of this high-risk group of older individuals.

Childhood trauma and cognitive deficits in patients with schizophrenia: mediation by orbitofrontal cortex H-shaped sulci volume

BACKGROUND

A line of evidence has shown that childhood trauma and patterns of H-shaped sulci in the orbitofrontal cortex (OFC) are associated with cognitive deficits in patients with schizophrenia. Studies have also suggested that childhood trauma is associated with OFC volumetrics. This study investigated the interrelationship between childhood trauma, OFC H-shaped sulci volume and cognitive function in patients with first-episode schizophrenia. We hypothesized that OFC H-shaped sulci volume would mediate the relationship between childhood trauma and cognitive function in patients with first-episode schizophrenia.

METHODS

We recruited patients with first-episode schizophrenia (n = 63) and healthy controls (n = 48), and quantified OFC H-shaped sulci volumes with 3.0 T high-resolution MRI. We assessed cognitive function and childhood trauma experiences using the MATRICS Consensus Cognitive Battery (MCCB) and the Childhood Trauma Questionnaire (CTQ).

RESULTS

Patients with first-episode schizophrenia had smaller left OFC H-shaped sulci volumes, more severe childhood trauma experiences and worse cognitive function than healthy controls. CTQ total score and emotional and physical neglect subscores were negatively correlated with left OFC H-shaped sulci volume. CTQ total score and emotional neglect and sexual abuse subscores were negatively correlated with cognitive function in patients with first-episode schizophrenia. Interestingly, the CTQ total score and physical neglect subscore were positively correlated with cognitive function in healthy controls. Left OFC H-shaped sulci volume played a mediating role in CTQ emotional neglect subscore, CTQ total score and MCCB composite score.

LIMITATIONS

The small sample size and retrospective design need to be considered.

CONCLUSION

Childhood trauma might contribute to cognitive deficits in patients with first-episode schizophrenia by affecting left OFC H-shaped sulci volume. This finding can help in the design of strategies to improve cognitive function in patients with first-episode schizophrenia.

Local understandings of PTSD and complex PTSD among health professionals working with adolescents in violent neighbourhoods of São Paulo city, Brazil

BACKGROUND

Adolescents in low-resource urban settings in Brazil are often exposed to high levels of trauma that can result in post-traumatic stress disorder (PTSD). However, preliminary evidence indicates that PTSD tends to be under-reported in Brazilian health services, despite the high prevalence of trauma. Additionally, little is known about the perceived applicability among clinicians of the new ICD-11 diagnosis of complex PTSD (CPTSD), despite its potential relevance for contexts of chronic trauma. The current study investigated local understandings of PTSD and CPTSD among health professionals working with adolescents in violent neighbourhoods of São Paulo city.

METHODS

Semi-structured interviews were conducted with 58 health professionals working at both the primary care and specialized mental health levels in two areas of São Paulo city with high levels of community violence.

RESULTS

Most participants knew about PTSD, but most did not know about CPTSD. There were mixed views concerning the commonality of PTSD among adolescents exposed to community violence. Many participants reported having no experience working with patients with the PTSD diagnosis. According to some, community violence was normalized by adolescents and health professionals, and did not result in PTSD. Others highlighted how they did not use psychiatric diagnoses in their practice, had critical perspectives towards psychiatric diagnoses and/or PTSD, or simply knew little about PTSD. Furthermore, many highlighted how the chronic nature of multiple traumas experienced by adolescents often resulted in complex clinical presentations characterised by many symptoms beyond PTSD. The diagnosis of CPTSD was considered appropriate to the context by many participants as it captured the complex traumatic histories and symptom presentations of adolescents exposed to community violence in Brazil.

CONCLUSIONS

These findings have important implications for the assessment and treatment of mental health among adolescents exposed to community violence in Brazil.

New directions in research on childhood adversity

Childhood adversities are major preventable risk factors for poor mental and physical health. Scientific advances in this area are not matched by clinical gains for affected individuals. We reflect on novel research directions that could accelerate clinical impact.

Misshandlungs- und Vernachlässigungserfahrungen in der Kindheit: Ein Risikofaktor für die soziale Teilhabe ehemals außerfamiliär platzierter junger Erwachsener

Zusammenfassung. Theoretischer Hintergrund: Eine Reihe von Studien zeigen soziale Folgen von Misshandlung und Vernachlässigung in der Kindheit im weiteren Lebenslauf. Fragestellung: Diese Studie zielt darauf ab, die langfristigen Auswirkungen von Misshandlungs- und Vernachlässigungserfahrungen auf die soziale Teilhabe in einer Stichprobe von ehemals fremdplatzierten jungen Erwachsenen in der Schweiz zu untersuchen. Methode: Im Rahmen der Studie wurden 218 ehemals fremdplatzierte junge Erwachsene ( MAlter=26.1, 32.6 % weiblich) mit einer psychometrischen Testbatterie befragt. Dabei wurden Misshandlungserfahrungen in der Kindheit erfasst sowie die soziale Teilhabe bezüglich psychischer Gesundheit, Legalbewährung, sozio-ökonomische Lage und Beziehungen untersucht. Ergebnisse: Die Ergebnisse zeigen die hohe Prävalenz und negativen Folgen von kumulierten Misshandlungserfahrungen bei ehemals fremdplatzierten jungen Menschen. Eine höhere Anzahl von Misshandlungserfahrungen ging mit signifikant mehr Problemen in gesundheitlichen, finanziellen und sozialen Lebensbereichen einher. Diskussion und Schlussfolgerung: Die gravierenden Folgen von Misshandlungserfahrungen in der Kindheit unterstreichen die Bedeutung der Prävention und frühzeitigen Intervention. Sie zeigen aber auch, dass viele schwer betroffene junge Menschen neben therapeutischen auch konkrete und lebensweltorientierte Hilfen benötigen, um ihre Entwicklungsaufgaben adäquat zu bewältigen und erfolgreich an der Gesellschaft teilzuhaben.
