Initial reliability and validity of the childhood trauma interview: a new multidimensional measure of childhood interpersonal trauma

Relations between adverse childhood experiences, racial and ethnic Identity, and cannabis use outcomes

Adverse childhood experiences (ACEs) and age of cannabis use onset are associated with cannabis use disorder (CUD), but their differential effect across race and ethnicity is unknown. Using NESARC-III, we examined ACEs, age of onset, and their interaction on lifetime cannabis use and CUD across racial and ethnic groups (Non-Hispanic White, Hispanic, Black/African American, Asian, American Indian/Alaska Native). ANOVAs found that American Indian/Alaska Native individuals reported the greatest prevalence of lifetime cannabis use and CUD, the greatest mean number of ACEs, and the earliest age of cannabis onset. Using logistic regressions, stratified by race and ethnic groups and adjusted for sociodemographic characteristics, we found that as ACEs increased, the odds of lifetime use (aORs 1.48-2.48), lifetime CUD (aORs 1.45-3.03), and past-year CUD (aORs 1.46-2.28) increased for all groups. The relations between ACEs and CUD were strongest among Asian/Pacific Islander respondents. Among respondents with lifetime use, increased age of onset was associated with lower lifetime CUD (aORs 0.85-0.94) and past-year CUD (aORs 0.88-0.97) for most groups. Three significant interactions between ACEs and age of onset predicting CUD emerged. Among Black and American Indian/Alaska Native individuals with an early age of cannabis initiation, ACEs exhibited a weaker relation with CUD. For White respondents, as number of ACEs increased, the impact of age of onset on CUD development diminished. Our findings highlight ACEs and age of onset as implicated in the progression from cannabis use to CUD and the importance of considering these factors in relation to racial and ethnic identity.

Early-Life Adversity Predicts Markers of Aging-Related Neuroinflammation, Neurodegeneration, and Cognitive Impairment in Women

OBJECTIVE

Despite the overwhelming evidence for profound and longstanding effects of early-life stress (ELS) on inflammation, brain structure, and molecular aging, its impact on human brain aging and risk for neurodegenerative disease is poorly understood. We examined the impact of ELS severity in interaction with age on blood-based markers of neuroinflammation and neurodegeneration, brain volumes, and cognitive function in middle-aged women.

METHODS

We recruited 179 women (aged 30-60 years) with and without ELS exposure before the onset of puberty. Using Simoa technology, we assessed blood-based markers of neuroinflammation and neurodegeneration, including serum concentrations of glial fibrillary acidic protein (GFAP) and neurofilament light chain (NfL). We further obtained T1-weighted and T2-weighted magnetic resonance images to assess brain volumes and we assessed cognitive performance sensitive to early impairments associated with the development of dementia, using the Cambridge Neuropsychological Automated Test Battery. We used generalized additive models to examine nonlinear interaction effects of ELS severity and age on these outcomes.

RESULTS

Analyses revealed significant nonlinear interaction effects of ELS severity and age on NfL and GFAP serum concentrations, total and subcortical gray matter volume loss, increased third ventricular volume, and cognitive impairment.

INTERPRETATION

These findings suggest that ELS profoundly exacerbates peripheral, neurostructural, and cognitive markers of brain aging. Our results are critical for the development of novel early prevention strategies that target the impact of developmental stress on the brain to mitigate aging-related neurological diseases.

The relationship between childhood trauma and internet addiction in adolescents with depression: the mediating role of insomnia and alexithymia

BACKGROUND

The correlation between depressive symptoms and internet addiction in adolescents is strengthened, and childhood trauma is an important predictor of internet addiction. However, the mechanism of childhood trauma on internet addiction in adolescents with depression remains unclear. This study investigates the current status and factors influencing internet addiction in adolescents with depression and further examines whether insomnia and alexithymia mediate childhood trauma and internet addiction in adolescents with depression.

METHODS

This study investigated 300 adolescent patients in 7 hospitals in Anhui province. General demographic characteristics such as age and gender were collected. The clinical characteristics of the patients were measured using the Childhood Trauma Questionnaire Short Form (CTQ-SF), Internet Addiction Test (IAT), Insomnia Severity Index (ISI) and 20-item Toronto Alexithymia Scale (TAS-20). PROCESS (Model 4) was used to examine the mediating effects of insomnia and alexithymia.

RESULTS

The prevalence of internet addiction among adolescents with depression was 50.2%. There were statistically significant differences between the internet addiction group and the non-internet addiction group in terms of relationships with classmates, relationships with teachers, family relations, and economic status. The total score of CTQ and its five subscale scores were significantly and positively correlated with the total score of IAT. Insomnia and externally oriented thinking (EOT) played a significant mediating role in the effect of physical neglect (PN) on internet addiction.

CONCLUSION

Insomnia and alexithymia play a significant mediating role between childhood trauma and internet addiction in adolescents with depression, which expand the existing understanding of internet addiction in adolescents with depression, and provide some theoretical references to address the problem of internet addiction in adolescents with depression and prevent the development of adolescent depression.

Lifestyle behaviours do not moderate the association between childhood maltreatment and comorbid depression and cardiometabolic disease in older adults: a meta-analysis

BACKGROUND

Comorbidity between depression and cardiometabolic diseases is an emerging health concern, with childhood maltreatment as a major risk factor. These conditions are also linked to unhealthy lifestyle behaviours such as physical inactivity, smoking, and alcohol intake. However, the precise degree to which lifestyle behaviours moderate the risk between childhood maltreatment and comorbid depression and cardiometabolic disease is entirely unknown.

METHODS

We analysed clinical and self-reported data from four longitudinal studies (Npooled = 181,423; mean follow-up period of 5-18 years) to investigate the moderating effects of physical activity, smoking, and alcohol intake, on the association between retrospectively reported childhood maltreatment and i) depression, ii) cardiometabolic disease and iii) their comorbidity in older adults (mean age range of 47-66 years). Estimates of these moderation effects were derived using multinomial logistic regressions and then meta-analysed.

RESULTS

No meaningful moderation effects were detected for any of the lifestyle behaviours on the association between childhood maltreatment and each health outcome. Physical activity was linked to lower odds of depression (OR [95% CI] = 0.94 [0.92; 0.96]), while smoking was a risk factor for all three outcomes (OR [95% CI] = 1.16 [1.04; 1.31] or larger). Alcohol intake was associated with slightly lower odds of comorbidity (OR [95% CI] = 0.69 [0.66; 0.73]), although this association was not stable across all sensitivity analyses.

CONCLUSIONS

Lifestyle behaviours did not moderate the risk association between childhood maltreatment and depression, cardiometabolic disease, and their comorbidity in older adults. However, we confirmed that childhood maltreatment was associated with these conditions. Further research should address the limitations of this study to elucidate the most optimal targets for intervention.

Associations between childhood maltreatment and personality traits in individuals with and without depression: a CTQ-based assessment

BACKGROUND

Prior research has established a correlation between childhood maltreatment (CM) and personality traits. The current understanding regarding the potential variability in the relationship between CM and its impact on personality dimensions among those with major depressive disorder (MDD) and healthy controls (HCs) remains elusive.

AIMS

This study analyzes the association between CM and personality traits in the MDD and HC groups.

METHODS

The study recruited 188 individuals with MDD and 132 HC. The Childhood Trauma Questionnaire (CTQ) was used to assess CM, and the Sixteen Personality Factor Questionnaire (16PF) was used to assess personality traits. We used a 2*2 analysis of covariance (ANCOVA) of the diagnosis and CM on 16PF, and hierarchical regression explored the association between specific types of CM and 16PF in both groups.

RESULTS

The 2*2 ANCOVA results indicated significant interaction effects between CM and diagnosis on personality traits, with CM's impact notably different between groups. In the MDD group, sexual abuse (SA) independently predicted the subscale Q1 (Openness to Change), related to the Big Five's openness. In the HC group, emotional abuse (EA) predicted the subscales C (emotional stability), O (apprehension), and Q4(tension), linked to Big Five's neuroticism.

CONCLUSION

The findings highlight the impact of early adversity on personality development, informing psychology and guiding tailored therapy development.

Deconstructing Cognitive Impairment in Psychosis With a Machine Learning Approach

Importance

Cognitive functioning is associated with various factors, such as age, sex, education, and childhood adversity, and is impaired in people with psychosis. In addition to specific effects of the disorder, cognitive impairments may reflect a greater exposure to general risk factors for poor cognition.

Objective

To determine the extent that impairments in cognition in psychosis reflect risk factor exposures.

Design, Setting, and Participants

This cross-sectional study examined the relationship between exposures and cognitive function using data from the Bipolar-Schizophrenia Network on Intermediate Phenotypes studies 1 and 2 across 6 sites. Participants included healthy controls; patients with schizophrenia, schizoaffective disorder, or bipolar I disorder with psychosis; and relatives of patients. Predictive modeling was performed using extreme gradient boosting regression to train a composite cognitive score prediction model with nested cross-validation. Shapley additive explanations values were used to examine the relationship between exposures and cognitive function.

Exposure

Exposures were chosen based on associations with cognition previously identified: age, sex, race and ethnicity, childhood adversity, education, parental education, parental socioeconomic status, parental age at birth, substance use, antipsychotic dose, and diagnosis.

Main Outcomes and Measures

Cognition was assessed using the Brief Assessment of Cognition in Schizophrenia.

Results

A total of 3370 participants were included: 840 healthy controls, 709 patients with schizophrenia, 541 with schizoaffective disorder, 457 with bipolar I disorder with psychosis, and 823 relatives of patients. The mean (SD) age was 37.9 (13.3) years; 1887 were female (56%) and 1483 male (44%). The model predicted cognitive scores with high accuracy: out-of-sample Pearson correlation between predicted and observed cognitive composite score was r = 0.72 (SD = 0.03). Individuals with schizophrenia (z = -1.4), schizoaffective disorder (z = -1.2), and bipolar I disorder with psychosis (z = -0.5) all had significantly worse cognitive composite scores than controls. Factors other than diagnosis and medication accounted for much of this impairment (schizophrenia z = -0.73, schizoaffective disorder z = -0.64, bipolar I disorder with psychosis z = -0.13). Diagnosis accounted for a lesser proportion of this deficit (schizophrenia z = -0.29, schizoaffective disorder z = -0.15, bipolar I disorder with psychosis z = -0.13), and antipsychotic use accounted for a similar deficit across diagnostic groups (schizophrenia z = -0.37, schizoaffective disorder z = -0.33, bipolar I disorder with psychosis z = -0.26).

Conclusions and Relevance

This study found that transdiagnostic factors accounted for a meaningful share of the variance in cognitive functioning in psychosis. A significant proportion of the cognitive impairment in psychosis may reflect factors relevant to cognitive functioning in the general population. When considering interventions, a diagnosis-agnostic, symptom-targeted approach may therefore be appropriate.

The Role of Gender in the Relationship Between Negative Reactions to Sexual Abuse Disclosure and Masculinity Norm Adherence

Although men and women generally receive positive and negative reactions to childhood sexual abuse (CSA) disclosure (Filipas & Ullman, 2001), negative reactions are more common (Gagnier & Collin-Vézina, 2016). Negative disclosure reactions - such as disbelieving, retaliating against, or distracting the survivor - are both prevalent and associated with poorer post-abuse recovery and well-being (Kennedy & Prock, 2018; Ullman, 2010). For male survivors in particular, the responses one receives from others following disclosure may complicate one's sense of masculinity. Thus, the present study explored the nature of the association between negative reactions to CSA disclosure and masculinity norm adherence between men and women who are CSA survivors. Participants (N = 299; Mage = 35.9; 52.8% women; 77.9% White) - who disclosed their CSA to at least one person - completed self-report measures pertaining to social reactions to CSA disclosure and adherence to various masculinity norms. Negative reactions to CSA disclosure were significantly, positively correlated with Winning (r = .20), Playboy (r = .42), Heterosexual Self-Presentation (r = .42), and Power over Women (r = .71) masculinity norms. Moderation analyses revealed that at low levels of negative reactions, men endorsed higher Power Over Women and Playboy adherence; at high levels of negative reactions, women endorsed these norms almost as much as men did. Findings highlight important differences in adherence that shed light on the impact of negative disclosures on masculine ideologies.

Patterns of Familial and Racial Trauma and Their Associations with Substance Use Disorders among Racial/Ethnic Minority Adults

BACKGROUND

Racial/ethnic minorities in the United States often experience many different types of traumatic events. We examine the patterns of familial and racial trauma and their associations with substance use disorders (SUDs) among racial/ethnic minority adults.

METHODS

We used data from the National Epidemiologic Survey of Alcohol and Related Conditions-III. The study sample included 17,115 individuals who were Hispanic (43.6%), Black (34.9%), Asian American and Pacific Islander (17.0%), and American Indian or Alaska Native (AI/AN, 4.6%). Latent class analysis models with covariates and distal outcomes were analyzed to investigate patterns of trauma exposure and estimate binary outcomes of SUDs. Familial and racial trauma was measured by ten areas of adverse childhood experiences (ACEs) and six items of racial discrimination.

RESULTS

We found four distinctive groups: low trauma (Class 1, 62.1%), high discrimination (Class 2, 17.2%), high ACEs (Class 2, 14.9%), and high trauma (Class 4, 5.9%). Compared to Class 1, other groups were more likely to include Black and AI/AN adults. Participants in Class 2 reported greater risks for alcohol and other drug use disorders. Those in Class 3 and 4 reported greater risks for alcohol, opioid, stimulant, and other drug use disorders.

CONCLUSION

Given a higher risk of trauma exposure in Black and AI/AN adults, racially and ethnically sensitive trauma-focused interventions may help prevent and reduce SUDs in those populations.

Ruminative thinking mediates the effects of exposure to adverse life events on psychotic-like experiences

Introduction

A growing literature has shown that exposure to adverse life events during childhood or adolescence is associated with the presence of psychotic-like experiences (PLEs), which is in turn associated with the risk of psychotic outcomes. Ruminative thinking, i.e., the tendency to dwell on particular issues or ideas, may affect the perceived aversiveness and ability to cope with adverse life events. However, the role that rumination plays in the relationship between adverse life events and the presence of PLEs remains unclear. The purpose of this study is to assess the association between adverse life events and PLEs in a longitudinal sample of young adults and adolescents, and to investigate whether this relationship is mediated by ruminative thinking.

Methods

We used a longitudinal naturalistic sample of 706 volunteers assessed at ages 18 and 22 years, within the Imagen consortium. Lifetime occurrence of adverse life events (i.e., events perceived as strongly negative by participants) was investigated using the Life Events Questionnaire. The Community Assessment of Psychic Experience (CAPE-42) served to assess the presence of PLEs, while ruminative thinking was investigated through the Ruminative Response Scale.

Results

Results showed that both frequency of PLEs and their persistence over time were associated with greater adverse life events exposure (r = 0.32, p < 0.001 and F 1 = 9.8; p < 0.001, respectively) and greater ruminative response (r = 0.66, p < 0.001 and F 1 = 94.9; p < 0.001, respectively). Mediation analyses showed that relationship between adverse life events and PLEs frequency was partially mediated by rumination (direct effect Z: 5.4, p < 0.001; indirect effect Z: 6.9, p < 0.001; total effect Z: 5.9, p < 0.001). Considering changes between the two assessment timepoints, relationship between PLEs variation between 18 and 22 years and adverse life events occurred during the same period was partially mediated by changes in rumination (direct effect Z: 2.8, p < 0.005; indirect effect Z: 4.3, p < 0.001; total effect Z: 4.3; p < 0.001).

Discussion

Overall, our findings confirm that the presence of adverse life events may increase the risk of experiencing PLEs in healthy individuals and suggest that dysfunctional coping strategies, such as ruminative thinking, may be related to psychosis proneness. Results do not disentangle whether individuals with greater risk for psychosis tend to ruminate more or whether rumination exacerbates psychosis risk.

Does child abuse predict a population segment with large economic burden?

OBJECTIVES

The enormous societal and individual consequences of mental health disorders and detrimental health behaviours in the general population are of paramount concern. Many argue that 'prevention is the best cure', pushing for the implementation of early (preventive) interventions. Key questions regarding early interventions include which population segment to target for screenings and what information these screenings should focus on. In line with previous efforts, this study aimed to identify which population segment holds the majority (≥ 80 %) of different economically costly outcomes in society, and whether child abuse before the age of 16 years predicts being part of that population segment.

STUDY DESIGN

Epidemiological cohort study.

METHODS

This study used the Netherlands Mental Health Survey and Incidence Study-2, a Dutch epidemiological cohort study including 6646 adults aged 18-64 years at baseline, spanning four timepoints from 2007 to 2018. Cumulative distributions were computed to identify high-cost population segments of economically costly outcomes in adulthood (i.e., mental and physical health [behaviours], unemployment and work absenteeism). Child abuse was examined as a potential predictor of these segments and the risk of multiple high-cost population segment membership was investigated by conducting Poisson regressions.

RESULTS

A 20 % population segment carried between 42 % and 100 % of economically costly outcomes. Being exposed to more child abuse predicted being in a high-cost population segment, albeit with small effect sizes. Being exposed to more child abuse also predicted belonging to multiple high-cost population segments across different economically costly outcomes.

CONCLUSIONS

The study findings have implications for policy makers. Emphasis should be placed on prevention aimed at identifying potential members of multiple high-cost population segments.

Why do prospective and retrospective measures of childhood maltreatment differ? Qualitative analyses in a cohort study

BACKGROUND

Research indicates that prospective and retrospective measures of maltreatment often identify different groups of individuals, yet the reasons for these discrepancies remain understudied.

OBJECTIVE

This study explores potential sources of disagreement between prospective and retrospective measures of maltreatment, utilising qualitative data from interviewers' notes.

PARTICIPANTS AND SETTING

The Environmental Risk Longitudinal Twin Study includes 2232 children followed from ages 5-18. Prospective measures relied on caregiver interviews and researcher observations from ages 5-12, while retrospective measures involved self-reports via the Childhood Trauma Questionnaire at age 18.

METHODS

We purposively sampled written interviewer notes from 36 participants who reported more types of maltreatment retrospectively than prospectively ('new reports' group) and 31 participants who reported fewer types retrospectively than prospectively ('omitted reports' group). We conducted a framework analysis of the notes, comparing between the two groups to explore explanations for measurement disagreement.

RESULTS

Three categories of themes emerged related to measurement discrepancies: challenges with prospective measures, highlighting reasons given by the 'new reports' group for why maltreatment went undetected or was not adequately responded to prospectively; challenges with retrospective measures that highlight difficulties with openness and accuracy of self-reports; and differences in appraisals of violence or distressing childhood experiences between the two groups that might lead to new or omitted retrospective reports.

CONCLUSIONS

Our findings underscore potential mechanisms underlying the disagreement between prospective and retrospective measures, contributing to better understanding of these different constructs and more balanced interpretation of related findings.

Borderline personality features in relationship to childhood trauma in unipolar depressive and bipolar disorders

BACKGROUND

Childhood trauma, including emotional neglect, emotional abuse, physical abuse, and sexual abuse, may contribute to borderline personality features like affective instability, identity problems, negative relationships, and self-harm. This study aims to explore how different types of childhood trauma affect these features in bipolar versus unipolar depressive disorders.

METHODS

We included 839 participants of the Netherlands Study of Depression and Anxiety (NESDA) with a lifetime diagnosis of major depressive disorder single episode (MDDS; N = 443), recurrent major depressive disorder (MDD-R; N = 331), or bipolar disorder (BD; N = 65). Multivariate regression was used to analyze data from the Childhood Trauma Interview and borderline features (from the self-report Personality Assessment Inventory).

RESULTS

On average, participants were 48.6 years old (SD: 12.6), with 69.2 % being women, and 50.3 % of participants assessed positive for childhood trauma. Adjusted analyses revealed that participants diagnosed with BD, followed by MDD-R, exhibited the highest number of borderline personality features. Additionally, within the entire group, a strong association was found between childhood trauma, especially emotional neglect, and the presence of borderline personality features.

CONCLUSION

Given the high prevalence of childhood trauma and borderline personality features, screening for these factors in individuals with mood disorders is crucial. Identifying these elements can inform and enhance the management of the often fluctuating and complex nature of these comorbid conditions, leading to more effective and tailored treatment strategies.

Altered dynamic functional connectivity of nucleus accumbens subregions in major depressive disorder: the interactive effect of childhood trauma and diagnosis

Major depressive disorder (MDD) with childhood trauma represents a heterogeneous clinical subtype of depression. Previous research has observed alterations in the reward circuitry centered around the nucleus accumbens (NAc) in MDD patients. However, limited investigations have focused on aberrant functional connectivity (FC) within NAc subregions among MDD with childhood trauma. Thus, this study adopts analyses of both static FC (sFC) and dynamic FC (dFC) to examine neurobiological changes in MDD with childhood trauma. The bilateral nucleus accumbens shell (NAc-shell) and nucleus accumbens core (NAc-core) were selected as the seeds. Four participant groups were included: MDD with childhood trauma (n = 48), MDD without childhood trauma (n = 30), healthy controls (HCs) with childhood trauma (n = 57), and HCs without childhood trauma (n = 46). Our findings revealed both abnormal sFC and dFC between NAc-shell and NAc-core and regions including the middle occipital gyrus (MOG), anterior cingulate cortex, and inferior frontal gyrus in MDD with childhood trauma. Furthermore, a significant correlation was identified between the dFC of the left NAc-shell and the right MOG in relation to childhood trauma. Additionally, abnormal dFC moderated the link between childhood abuse and depression severity. These outcomes shed light on the neurobiological underpinnings of MDD with childhood trauma.

Validation of the Childhood Trauma Questionnaire - Short Form (CTQ-SF) for a French-Speaking Sample

The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a widely used and standardized questionnaire designed to assess five types of childhood abuse. Despite the fact that the CTQ-SF demonstrates good validity and reliability, its internal structure presents some limitations and its original 28-item five-factor model has been contested. The present study assesses the reliability and the factor structure of a French version of the CTQ-SF for an alternative 25-item model and a bifactorial model, using confirmatory factor analysis (CFA). Participants were French-speaking females from two independent samples (N = 1903, N = 690). They completed an online sociodemographic questionnaire and the online version of the CTQ-SF. The new model proposed in this article demonstrated excellent fit indices in two independent samples. Our results support the fit of a bifactorial 25-item model, suggesting the presence of a general factor of intrafamilial maltreatment, from which only sexual abuse would be separated. Furthermore, the results support the fit of a solution with seven factors. This research proposes alternative models that address the limitations pinpointed by previous international studies and demonstrate good fit indices. Moreover, these findings provide support for the validity of a French version of the CTQ-SF.

Childhood trauma in bipolar affective disorder: A case control study

Background

The etiology of Bipolar Affective Disorder (BPAD) is influenced by a variety of factors, possibly related to gene-environment interactions. Childhood trauma (CT) has been associated with an increased risk of developing BPAD. It also impacts the course of illness. The association of subcomponents of CT with BPAD and its various characteristics has not been studied in detail.

Aim

This study was conducted to evaluate the association of CT with BPAD and compare it with age and sex-matched healthy controls.

Materials and Methods

Fifty cases of BPAD diagnosed as per International Classification Diseases 10 (Diagnostic Criteria for Research) and 50 years age and sex-matched healthy control were studied. The required sample size was 38. Assessment of CT was done using the Childhood Trauma Questionnaire and statistical methods were applied.

Results

Among all cases of BPAD, 38 (76%) cases had experienced moderate to severe CT as compared to 10 (20%) of controls. This was statistically significant. All subtypes of CT were significantly associated with BPAD as compared to healthy controls. Among subtypes, emotional abuse had the highest association with BPAD (odds ratio 7.37, confidence interval 1.98-27.31).

Conclusion

CT is significantly associated with BPAD. All subtypes of CT are associated with BPAD and among them, emotional abuse appeared to exert the biggest impact. A multicentric study with larger sample sizes will further substantiate this finding regarding subtypes.

An Exploration of Racial Differences Among Male Youth Adjudicated for Sexual Offenses

In 2019, the male adjudicated youth (AY) population in correctional facilities was 33% White and 67% minority. Yet, the distribution among male AY charged with sexual offenses (AYSOs) was 55% White and 45% minority, highlighting the lack of disproportionate minority contact within the AYSO population. Little research on AYSOs has focused explicitly on exploring racial differences within this population. Using secondary data from 720 AY 11-18 years of age, the goal of this exploratory study was to identify differences in length of detention, presence of clinical syndromes, attachment patterns, and childhood trauma experiences among a sample of AYSOs and AYs by race category. Although few racial differences were identified among AYSOs, study results overwhelmingly highlighted differences between AYSOs and AYs.

Trajectories of depressive symptoms early in the course of bereavement: Patterns, psychosocial factors and risk of prolonged grief

In the context of bereavement, little is known about the mechanisms that differentiate normative adjustment patterns from those that may indicate potential psychopathology. This study aimed to replicate and extend previous work by (1) characterizing the trajectories of depressive symptoms from 3 to 12 months after the loss of a spouse, (2) examining whether (a) childhood maltreatment and attachment style predicted distinct depression trajectories, and (b) different depression trajectories were associated with the risk of prolonged grief at 12 months post-loss. Recently bereaved individuals (N = 175) completed self-report assessments at 3, 4, 6, and 12-months post-loss. Trajectories of depressive symptoms were estimated using group-based trajectory modelling. Four distinct trajectories of depressive symptoms were identified: (1) resilience (minimal/no depression across time points; 45%), (2) moderate depression-improved (alleviated to 'mild' by 12 months; 31%), (3) severe depression-improved (alleviated to 'moderate' by 12 months; 15%), and (4) chronic depression ('severe' symptoms across time points; 9%). Higher childhood maltreatment predicted a greater likelihood of belonging to the 'severe depression-improved' and 'chronic depression' groups than the 'resilient' and 'moderate depression-improved' groups. Widow(er)s with higher attachment anxiety were more likely to belong to the 'severe depression-improved' and 'chronic depression' groups than the 'resilient' group. The trajectory groups with persistent levels of depressive symptoms up until 6 months were more likely to exhibit prolonged grief at 12 months post-loss. Changes from pre-loss functioning cannot be estimated. Our findings provide insight into the early identification of post-loss prolonged grief.

Adverse childhood experiences among people with schizophrenia at comprehensive specialized hospitals in Bahir Dar, Ethiopia: a comparative study

Background

People who have encountered adverse childhood experiences (ACEs) are predisposed to developing schizophrenia, experiencing exacerbated symptoms, and facing an elevated risk of disease relapse. It is imperative to evaluate the prevalence of ACEs to comprehend the specific attributes of this condition and enable the implementation of suitable interventions.

Aims

The aim of this study was to assess the prevalence of ACEs and its determinants among people with schizophrenia and the patient attendants in Bahir Dar, Ethiopia.

Method

A comparative cross-sectional study was carried out at the Comprehensive Specialized Hospitals in Bahir Dar, Ethiopia, from April 26 to June 10, 2023. A total of 291 individuals with schizophrenia and 293 individuals from the patient attendants were selected using a systematic random sampling method. A proportional odds model ordinal logistic regression analysis was used to identify the factors associated with ACEs.

Results

The occurrence of at least one ACE among individuals diagnosed with schizophrenia was 69.4%, while patient attendants had a 46.8%, as indicated by the Chi-square test, which showed a significant difference at p <0.05. The study findings indicated that individuals with schizophrenia who have encountered four or more ACEs are more inclined to have lower educational attainment (AOR: 4.69 [1.94 - 11.61]), low resilient coping mechanisms (AOR: 2.07 [1.11 - 3.90]), and poor social support (AOR: 3.93 [2.13 - 7.32]). Conversely, factors such as rural residency, illiteracy, and heightened attachment-related anxiety were found to be notably associated with the patient attendants.

Conclusion

In this study, the substantial prevalence of ACEs emphasized the necessity for ACE screening and the implementation of evidence-based interventions to address and alleviate the overall burden of ACEs.

Hyperbaric oxygen therapy vs. pharmacological intervention in adults with fibromyalgia related to childhood sexual abuse: prospective, randomized clinical trial

Fibromyalgia syndrome (FMS) is a chronic pain syndrome characterized by disruptions in pain processing within the central nervous system. It exhibits a high prevalence among patients with a history of traumatic experiences, notably childhood sexual abuse (CSA). This study compared the efficacy of hyperbaric oxygen therapy (HBOT) to the current pharmacological standard of care for individuals suffering from CSA-related FMS. Forty-eight participants diagnosed with FMS and a history of CSA were randomly assigned to either the HBOT group (60 sessions of 100% oxygen at 2 ATA for 90 min, with air breaks every 5 min) or the medication (MED) group (FDA-approved medications, Pregabalin and Duloxetine). The primary endpoint was the Fibromyalgia impact questionnaire (FIQ) score, while secondary endpoints encompassed emotional status and daily functioning questionnaires, as well as pain thresholds and conditioned pain modulation tests. Brain activity was evaluated through single photon emission computed tomography (SPECT). Results revealed a significant group-by-time interaction for the FIQ score favoring HBOT over MED (p < 0.001), with a large effect size (Cohen's d = - 1.27). Similar findings were observed in emotional symptoms and functional measures. SPECT imaging demonstrated an increase in activity in pre-frontal and temporal brain areas, which correlated with symptoms improvement. In conclusion, HBOT exhibited superior benefits over medications in terms of physical, functional, and emotional improvements among FMS patients with a history of CSA. This associated with increased activity in pre-frontal and temporal brain areas, highlighting the neuroplasticity effect of HBOT.

Brain alterations in adolescents with first-episode depression who have experienced adverse events: evidence from resting-state functional magnetic resonance imaging

Introduction

Adverse life events constitute primary risk factors for major depressive disorder (MDD), influencing brain function and structure. Adolescents, with their brains undergoing continuous development, are particularly susceptible to enduring impacts of adverse events.

Methods

We investigated differences and correlations among childhood trauma, negative life events, and alterations of brain function in adolescents with first-episode MDD. The study included 23 patients with MDD and 19 healthy controls, aged 10-19 years. All participants underwent resting-state functional magnetic resonance imaging and were assessed using the beck depression inventory, childhood trauma questionnaire, and adolescent self-rating life events checklist.

Results

Compared with healthy controls, participants with first-episode MDD were more likely to have experienced emotional abuse, physical neglect, interpersonal relationship problems, and learning stress (all p' < 0.05). These adverse life events were significantly correlated with alterations in brain functions (all p < 0.05).

Discussion

This study contributes novel evidence on the underlying process between adverse life events, brain function, and depression, emphasizing the significant neurophysiological impact of environmental factors.

Day-to-day affect fluctuations in adults with childhood trauma history: a two-week ecological momentary assessment study

BACKGROUND

Childhood trauma (CT) may increase vulnerability to psychopathology through affective dysregulation (greater variability, autocorrelation, and instability of emotional symptoms). However, CT associations with dynamic affect fluctuations while considering differences in mean affect levels across CT status have been understudied.

METHODS

346 adults (age = 49.25 ± 12.55, 67.0% female) from the Netherlands Study of Depression and Anxiety participated in ecological momentary assessment. Positive and negative affect (PA, NA) were measured five times per day for two weeks by electronic diaries. Retrospectively-reported CT included emotional neglect and emotional/physical/sexual abuse. Linear regressions determined associations between CT and affect fluctuations, controlling for age, sex, education, and mean affect levels.

RESULTS

Compared to those without CT, individuals with CT reported significantly lower mean PA levels (Cohen's d = -0.620) and higher mean NA levels (d = 0.556) throughout the two weeks. CT was linked to significantly greater PA variability (d = 0.336), NA variability (d = 0.353), and NA autocorrelation (d = 0.308), with strongest effects for individuals reporting higher CT scores. However, these effects were entirely explained by differences in mean affect levels between the CT groups. Findings suggested consistency of results in adults with and without lifetime depressive/anxiety disorders and across CT types, with sexual abuse showing the smallest effects.

CONCLUSIONS

Individuals with CT show greater affective dysregulation during the two-week monitoring of emotional symptoms, likely due to their consistently lower PA and higher NA levels. It is essential to consider mean affect level when interpreting the impact of CT on affect dynamics.

Epidemiology of social phobia in Andalusia

INTRODUCTION

Population studies on social anxiety disorder (SAD) are relatively scarce and there is no previous reported evidence on prevalence or correlates of SAD in an Andalusian general population sample.

MATERIAL AND METHODS

We used a random representative sample previously identified via standard stratification procedures. Thus, a final sample of 4507 participants were included (response rate 83.7%). Interviewees were thoroughly assessed on sociodemographic, clinical and psychosocial factors, including: exposures to threatening life events (TLEs), childhood abuse, personality disorder and traits (neuroticism, impulsivity, paranoia), global functioning, physical health and toxics consumption. SAD diagnosis was ascertained using the Mini International Neuropsychiatric Interview. Both, pooled prevalences (with 95% confidence intervals) and risk correlates for SAD were estimated using binary logistic regression.

RESULTS

Estimated prevalence for SAD was 1.1% (95% CI=0.8-1.4). Having a SAD diagnosis was independently and significantly associated with younger age, poorer global functioning, higher neuroticism and paranoia personality traits, having suffered childhood abuse and exposure to previous TLEs. Furthermore, SAD was significantly associated with comorbid personality disorder, major depression, panic disorder and alcohol abuse.

CONCLUSIONS

Among this large Andalusian population sample, the prevalence of SAD and its associated factors are relatively similar to previously reported international studies, although no population study had previously reported such a strong association with paranoia.

The neurobiological effects of childhood maltreatment on brain structure, function, and attachment

Childhood maltreatment is a risk factor for psychopathologies, and influences brain development at specific periods, particularly during early childhood and adolescence. This narrative review addresses phenotypic alterations in sensory systems associated with specific types of childhood maltreatment exposure, periods of vulnerability to the neurobiological effects of maltreatment, and the relationships between childhood maltreatment and brain structure, function, connectivity, and network architecture; psychopathology; and resilience. It also addresses neurobiological alterations associated with maternal communication and attachment disturbances, and uses laboratory-based measures during infancy and case-control studies to elucidate neurobiological alterations in reactive attachment disorders in children with maltreatment histories. Moreover, we review studies on the acute effects of oxytocin on reactive attachment disorder and maltreatment and methylation of oxytocin regulatory genes. Epigenetic changes may play a critical role in initiating or producing the atypical structural and functional brain alterations associated with childhood maltreatment. However, these changes could be reversed through psychological and pharmacological interventions, and by anticipating or preventing the emergence of brain alterations and subsequent psychopathological risks.

Major stress in early childhood strengthens the association between peripheral inflammatory activity and corticostriatal responsivity to reward

BACKGROUND

Severe, chronic stress during childhood accentuates vulnerability to mental and physical health problems across the lifespan. To explain this phenomenon, the neuroimmune network hypothesis proposes that childhood stressors amplify signaling between peripheral inflammatory cells and developing brain circuits that support processing of rewards and threats. Here, we conducted a preliminary test of the basic premises of this hypothesis.

METHODS

180 adolescents (mean age = 19.1 years; 68.9 % female) with diverse racial and ethnic identities (56.1 % White; 28.3 % Hispanic; 26.1 % Asian) participated. The Childhood Trauma Interview was administered to quantify early adversity. Five inflammatory biomarkers were assayed in antecubital blood - C-reactive protein, tumor necrosis factor-a, and interleukins-6, -8, and -10 - and were averaged to form a composite score. Participants also completed a functional MRI task to measure corticostriatal responsivity to the anticipation and acquisition of monetary rewards.

RESULTS

Stress exposure and corticostriatal responsivity interacted statistically to predict the inflammation composite. Among participants who experienced major stressors in the first decade of life, higher inflammatory activity covaried with lower corticostriatal responsivity during acquisition of monetary rewards. This relationship was specific to participants who experienced major stress in early childhood, implying a sensitive period for exposure, and were evident in both the orbitofrontal cortex and the ventral striatum, suggesting the broad involvement of corticostriatal regions. The findings were independent of participants' age, sex, racial and ethnic identity, family income, and depressive symptoms.

CONCLUSIONS

Collectively, the results are consistent with hypotheses suggesting that major stress in childhood alters brain-immune signaling.

The role of the thalamic subregions in major depressive disorder with childhood maltreatment: Evidences from dynamic and static functional connectivity

BACKGROUND

Major depressive disorder (MDD) with a history of childhood maltreatment represents a highly prevalent clinical phenotype. Previous studies have demonstrated functional alterations of the thalamus among MDD. However, no study has investigated the static and dynamic changes in functional connectivity (FC) within thalamic subregions among MDD with childhood maltreatment.

METHODS

This study included four groups: MDD with childhood maltreatment (n = 48), MDD without childhood maltreatment (n = 30), healthy controls with childhood maltreatment (n = 57), and healthy controls without childhood maltreatment (n = 46). Sixteen thalamic subregions were selected as seed to investigate group-differences in dynamic FC (dFC) and static FC (sFC). Correlation analyses were performed to assess the associations between abnormal FC and maltreatment severity. Eventually, moderation analyses were employed to explore the moderating role of abnormal FC in the relationship between maltreatment and depressive severity.

RESULTS

MDD with childhood maltreatment exhibit abnormal thalamic subregions FC compared to MDD without childhood maltreatment, characterized by abnormalities with the sFC of the rostral anterior cingulate cortex, with the dFC of the calcarine, middle cingulate cortex, precuneus cortex and superior temporal gyrus. Furthermore, sFC with the rostral anterior cingulate cortex and dFC with the middle cingulate cortex were correlated with the severity of maltreatment. Additionally, dFC with the superior temporal gyrus moderates the relationship between maltreatment and depression severity.

LIMITATIONS

The cross-sectional designs fail to infer causality.

CONCLUSIONS

Our findings support thalamic dysfunction as neurobiological features of childhood maltreatment as well as vulnerability to MDD.

An epidemiological survey on personality disorder in Andalusia (the PISMA-ep PD study)

BACKGROUND

Despite a significant clinical and social burden, there is a relative scarcity of epidemiological studies on Personality Disorder (PD).

AIM

To determine the current prevalence of PD and the psychosocial correlates associated with this in the Andalusian population.

METHOD

We carried out a cross-sectional population mental-health survey in Andalusia, southern Spain. Thus, 4,518 randomly selected participants were interviewed following sampling using different standard stratification levels. We used the Spanish version of the SAPAS to estimate PD prevalence. In addition, a full battery of other instruments was utilized to explore global functionality, childhood abuse, maltreatment, threatening life events, personality traits (neuroticism, impulsivity and paranoia), medical and psychiatric comorbidities, family history of psychological problems and other potential risk factors for PD.

RESULTS

PD prevalence (10.8%; 95% CI [9.8, 11.7]) and ran two different multivariate models for PD. We obtained the highest PD prevalence in those affected by any mental disorder plus those reporting having suffered childhood abuse, particularly sexual abuse. Additional potential risk factors or correlates of PD identified were: younger age, lower levels of functioning, less social support, poorer general health, having suffered maltreatment, threatening life events, higher suicidal risk scores and higher levels of both neuroticism and impulsivity.

CONCLUSIONS

This study reports PD prevalence and risk correlates in consonance with similar findings reported in other Western populations. However, longitudinal studies are needed to elicit a more thorough group of prospective determinants of PD.

Longitudinal polysubstance use patterns and non-fatal overdose: A repeated measures latent class analysis

BACKGROUND

Polysubstance use (PSU) is common among people who use opioids (PWUO) and has been associated with drug-related harms. We aimed to identify latent longitudinal PSU classes among a cohort of PWUO and characterize non-fatal overdose risks among different sub-classes over time.

METHODS

We used longitudinal data (2005-2018) from three ongoing prospective cohorts of people who use drugs in Vancouver, Canada. The primary outcome of interest was self-reported non-fatal overdose during the past six months. The primary exposure of interest was longitudinal PSU patterns among PWUO, obtained from repeated measures latent class analysis (RMLCA) of weekly substance use-related outcome indicators. Multivariable generalized estimating equations models were built to assess the association between latent PSU class membership and non-fatal overdose, adjusting for potential sociodemographic, behavioural, and structural confounders.

RESULTS

2627 PWUO were included in the analysis, and 1094 (41.6 %) had experienced at least one non-fatal overdose during the study period. RMLCA revealed five distinct latent longitudinal PSU classes, including low/infrequent use (Class 1; 30 %), primarily opioid and methamphetamine use (Class 2; 22 %), primarily cannabis use (Class 3; 15 %), primarily opioid and crack use (Class 4; 29 %), and frequent PSU (Class 5; 4 %). In comparison with Class 1 (low), membership in all latent PSU classes except Class 3 (cannabis) was associated with increased odds of non-fatal overdose: Class 2 (opioids + meth) vs. Class 1 (Adjusted odds ratios [aOR] = 2.20, 95 % confidence intervals [CI]: 1.51-3.22), Class 4 (opioids + crack) vs. Class 1 (aOR = 1.06, 95 % CI: 0.85-1.33), and Class 5 (frequent) vs. Class 1 (aOR = 2.39, 95 % CI: 1.92-2.97).

CONCLUSION

Our findings highlighted the heterogeneous characteristics of PWUO in terms of patterns of PSU and non-fatal overdose risk. The diverse nature of PWUO and the potential additive or multiplicative impact of using several substances on overdoses should be reflected across the substance use treatment continuum and care provision.

Psychometric properties of the Hungarian childhood trauma questionnaire short form and its validity in patients with adult attention-deficit hyperactivity disorder or borderline personality disorder

BACKGROUND

Compelling evidence supports the role of childhood traumatization in the etiology of psychiatric disorders, including adult attention-deficit hyperactivity disorder (aADHD) and borderline personality disorder (BPD). The aim of this study was to examine the psychometric properties of the Hungarian version of the Childhood Trauma Questionnaire Short Form (H-CTQ-SF) and to investigate the differences between patients diagnosed with aADHD and BPD in terms of early traumatization.

METHODS

Altogether 765 (mean age = 32.8 years, 67.7% women) patients and control subjects were enrolled from different areas of Hungary. Principal component analysis and confirmatory factor analysis were carried out to explore the factor structure of H-CTQ-SF and test the validity of the five-factor structure. Discriminative validity was assessed by comparing clinical and non-clinical samples. Subsequently, aADHD and BPD subgroups were compared with healthy controls to test for the role of early trauma in aADHD without comorbid BPD. Convergent validity was explored by measuring correlations with subscales of the Personality Inventory for DSM-5 (PID-5).

RESULTS

The five scales of the H-CTQ-SF demonstrated adequate internal consistency and reliability values. The five-factor model fitted the Hungarian version well after exclusion of one item from the physical neglect scale because of its cross-loading onto the emotional neglect subscale. The H-CTQ-SF effectively differentiated between the clinical and non-clinical samples. The BPD, but not the aADHD group showed significant differences in each CTQ domain compared with the healthy control group. All CTQ domains, except for physical abuse, demonstrated medium to high correlations with PID-5 emotional lability, anxiousness, separation insecurity, withdrawal, intimacy avoidance, anhedonia, depressivity, suspiciousness, and hostility subscales.

CONCLUSIONS

Our study confirmed the psychometric properties of the H-CTQ-SF, an easy-to-administer, non-invasive, ethically sound questionnaire. In aADHD patients without comorbid BPD, low levels of traumatization in every CTQ domain were comparable to those of healthy control individuals. Thus, the increased level of traumatization found in previous studies of aADHD might be associated with the presence of comorbid BPD. Our findings also support the role of emotional neglect, emotional abuse and sexual abuse in the development of BPD.

The Associations of Adverse Childhood Experiences (ACEs) With Substance Use in Young Adults: A Systematic Review

Introduction

Young adulthood is a transitional period between adolescence and adulthood. Due to the unique pressures of taking on a new social role and associated uncertainties, young adults are at heightened risk for drug and alcohol use. Furthermore, adverse childhood experiences (ACEs) increases the likelihood of using maladaptive coping strategies such as using substances to avoid or soothe negative emotions. The current review aimed to summarize the associations between exposure to ACEs before the age of 18 years and subsequent drug or alcohol use between the ages of 18 and 25 years.

Methods

The review was performed in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The literature search of the Web of Science, PubMed, and PsycINFO databases was conducted in February 2022.

Results

The initial search yielded 7178 articles, with 777 duplicates. Consequently, 6401 titles were inspected for relevance. After reading the full text, 88 articles were included in the review.

Conclusion

This review provides clear evidence that exposure to multiple ACEs is a robust risk factor for the use of alcohol, cannabis and other drugs by young adults. Poor self-regulation and maladaptive coping strategies were identified as mechanisms explaining this link; however, further detailed research is needed.

Emotion regulation and cognitive function as mediating factors for the association between lifetime abuse and risky behaviors in women of color

BACKGROUND

The relationship between lifetime abuse (i.e., childhood abuse, intimate partner violence) and risky behaviors is well established. One proposed mechanism is poor emotion regulation and executive functioning, as a potential mechanism that may explain the relationship between lifetime abuse and risky behaviors. However, research on executive functioning and emotion regulation as mediators of this relationship has been limited. In the present study, we examined this association. We hypothesized that lifetime abuse would be significantly associated with executive function and emotion regulation which in turn would be associated with greater alcohol use and risky sex.

METHODS

This cross-sectional study included 150 women with a history of lifetime abuse who were assessed for hazardous alcohol use using the AUDIT Score; emotion regulation was measured using the Difficulties with Emotion Regulation Scale (DERS); risky sex was measured using the question: "in the last 90 days, how many people did you have anal or vaginal sex without using a condom? Executive function was assessed using the NIH Toolbox.

RESULTS

The mediation model followed the self-regulation theory, which proposes executive function as the higher-order cognitive process. Results showed that executive function deficit and poor emotion regulation significantly mediated the relationship between lifetime abuse and hazardous alcohol use (indirect effect = .097, SE .031, 95% CI = .035 to .158).

CONCLUSION

Our findings suggest a higher-order cognitive process with executive function promoting emotion regulation as a potential mechanism for alcohol problems in women of color who experienced lifetime abuse.

Experiences of adversity in childhood and adolescence and cortisol in late adolescence

Early life adversity influences the diurnal cortisol rhythm, yet the relative influence of different characteristics of adversity remains unknown. In this study, we examine how developmental timing (childhood vs. adolescence), severity (major vs. minor), and domain of early life adversity relate to diurnal cortisol rhythms in late adolescence. We assessed adversity retrospectively in early adulthood in a subsample of 236 participants from a longitudinal study of a diverse community sample of suburban adolescents oversampled for high neuroticism. We used multilevel modeling to assess associations between our adversity measures and the diurnal cortisol rhythm (waking and bedtime cortisol, awakening response, slope, and average cortisol). Major childhood adversities were associated with flatter daily slope, and minor adolescent adversities were associated with greater average daily cortisol. Examining domains of childhood adversities, major neglect and sexual abuse were associated with flatter slope and lower waking cortisol, with sexual abuse also associated with higher cortisol awakening response. Major physical abuse was associated with higher waking cortisol. Among adolescent adversities domains, minor neglect, emotional abuse, and witnessing violence were associated with greater average cortisol. These results suggest severity, developmental timing, and domain of adversity influence the association of early life adversity with stress response system functioning.

[Diagnostic criteria, epidemiology and assessment of patients with functional neurological disorders]

Functional neurological disorders (FND) are symptoms that can affect a variety of functions including motor, sensory and cognitive. These symptoms are genuinely experienced by the patient and are related to a functional disorder rather than a structural one. There is little epidemiological data on these disorders, but their frequency is well established in clinical practice, it is the second most frequent reason for consultation in Neurology. Despite of the frequency of the disorder, general practitioners and specialists are insufficiently trained in the disease, and patients often suffer from stigmatization and/or unnecessary investigations. It is therefore important to be aware of the diagnostic approach to FND, which mostly relies on positive clinical signs. Psychiatric evaluation can help with the characterization of predisposing, precipitating and perpetuating factors of the symptoms (according to the 3P biopsychosocial model related to FND), and guide their management. Finally, diagnosis explanation is a crucial step in the management of the disease, which can in itself have a therapeutic effect, and allow the patient to adhere to the treatments.

Oxytocin system polymorphisms rs237887 and rs2740210 variants increase the risk of depression in pregnant women with early abuse

Prepartum depression is associated with early adversity, pregnancy complications, preterm delivery, postpartum depression, and long-term effects on child neurodevelopment. The oxytocin (OXT) system is affected by early adverse experiences and has been associated with depression. In the current study, we investigated risk factors for prenatal depressive symptoms, mainly the effects of early childhood and adolescence trauma, in combination with the presence of certain variants of polymorphisms of OXT and OXT receptor (OXTR) genes. We hypothesized that early childhood and adolescence trauma has higher negative effects in carriers of genetic variants of the OXT/OXTR system, increasing their risk for depression. Early in pregnancy (8-14 weeks), 141 pregnant women from a Uruguayan population were asked to provide DNA samples and complete questionnaires that assessed their experience of child abuse, depression symptoms, and other variables that included demographic information. Our results showed that 23.5% of pregnant women had depressive symptoms. Several OXT and OXTR genetic variants were associated with higher risk of prepartum depression only in those pregnant women who suffered emotional abuse during infancy or adolescence. Logistic regression (Nagelkerke's R2  = .33) revealed that women who suffered early abuse and were carriers of the variants CC of rs2740210 (OXT) or AA of rs237887 (OXTR) had significantly higher risk of experiencing depressive symptoms. Antecedents of psychiatric disorders also contributed to the risk of depression. We conclude that emotional abuse contributes to the risk of depression in different ways in women carrying different OXT and OXTR genetic variants. Early detection and closer follow-up of women with child abuse and certain OXT genetic variants, among other risk factors, could reduce the long-term impact of prepartum depression.

From criminal interrogations to investigative interviews: a bibliometric study

This paper presents the results of a bibliometric study providing a comprehensive overview of the social science research conducted on criminal interrogations and investigative interviews since the 1900s. The objectives are to help researchers to further understand the research field, to better communicate research findings to practitioners, to help practitioners understand the breadth of scientific knowledge on criminal interrogations and investigative interviews, and to foster dialog between researchers and practitioners. To begin, after a brief description of Web of Science, we describe how we developed our database on criminal interrogations and investigative interviews. Then, we report the yearly evolution of articles, the journals where they were published, the research areas covered by this research field, as well as the authors, the institutions and the countries that published the most on a variety of topics related to criminal interrogations and investigative interviews. Finally, we present the most used keywords and the most cited articles, and examine the research on questionable tactics and techniques in the research field of criminal interrogations and investigative interviews. This paper ends with a critical look at the results, for the benefit of researchers and practitioners interested in criminal interrogations and investigative interviews.

Behavioural clusters characteristic of cardiovascular reactivity profiles relate to poorer health outcomes

OBJECTIVES

Blunted cardiovascular reactivity is associated with a distinct behavioural profile of greater exposure to early life adversity, coupled with higher levels of behavioural disengagement and symptoms of depression. The present study sought to extend on this work by investigating if behavioural clusters with distinct patterns of reactivity were related to health and behavioural outcomes at baseline and at a 4-year follow-up.

METHODS

Hierarchical cluster analyses were conducted using longitudinal data drawn from the Midlife Development in the United States (MIDUS 2) Biomarker Project and the MIDUS 3 follow-up 4 years later. During MIDUS, 2 participants (N = 513) underwent a standardized stress testing protocol and had their blood pressure and heart rate monitored throughout. In addition, hierarchical cluster analyses were conducted on responses from measures of early life adversity, behavioural disengagement and depression. Binary logistic regressions were conducted to determine whether cluster membership was related to health and behavioural outcomes which were taken at both time points.

RESULTS

Three behavioural clusters emerged with statistically different blood pressure reactivity patterns. The cluster characterized by greater exposure to early life adversity, higher levels of behavioural disengagement and depressive symptoms, had relatively lower blood pressure reactivity patterns compared with both the exaggerated reactivity cluster and the cluster similar to the sample mean. In fully adjusted models, this cluster was associated with hypertension (p = .050) and depressed affect (p = .033), while Cluster 1 characteristic of an exaggerated blood pressure reactivity profile was associated with depressed affect (p < .001). Cluster membership did not significantly predict future health status.

CONCLUSION

This study extends research on behavioural clusters characteristic of reactivity profiles to demonstrate how they relate to health and behavioural outcomes during MIDUS 2.

Rumination Mediates the Relationship Between Childhood Traumas with Cognitive Defusion, Acceptance, and Emotion Regulation: A Qualitative and Quantitative Study

This study examines the intermediary role of rumination in the relationship between childhood traumas in young adults and cognitive defusion, psychological acceptance, and suppression which is one of the emotion regulation strategies. In the quantitative stage of the study formed according to the explanatory sequential design, the intermediary role of rumination by using a structural equation model while in the qualitative stage, the intermediary role of rumination was analyzed through interviews using the interpretive phenomenology design. Personal Information Form, Childhood Trauma Scale, Short Form Ruminative Response Scale, Acceptance and Action Form II, Drexel Defusion Scale, and Emotion Regulation Scale were used in the research. At the end of the research, it was determined that childhood traumas have a negative effect on cognitive defusion and acceptance, while they have a positive effect on suppression. It was seen that rumination has a partial intermediary role in the relationship of childhood traumas with cognitive defusion, acceptance, and suppression. As a result of the qualitative analysis, twelve themes such as "Constantly thinking about the past, not being able to move away from childhood traumas, not being able to forgive their parents, inability to get rid of negative thoughts, living in the past, moving away from a value-driven life, false expression of emotion, suppression of emotions, emotions reflected in behavior, coping with negative emotions and desired emotion regulation" emerged concerning participants' experiences of cognitive defusion, acceptance, and suppression. Although one of the purposes of using AAQ-II in the study was to support discussions about the scale via qualitative results, this was a limitation for the study. Therefore, although a high rate was obtained, it is not possible to infer that childhood traumas and rumination can explain acceptance behaviors. For this, much more quantitative and qualitative studies are needed. Other qualitative research findings are thought to support quantitative research findings.

The relative and interactive impact of multiple risk factors in schizophrenia spectrum disorders: a combined register-based and clinical twin study

BACKGROUND

Research has yielded evidence for genetic and environmental factors influencing the risk of schizophrenia. Numerous environmental factors have been identified; however, the individual effects are small. The additive and interactive effects of multiple risk factors are not well elucidated. Twin pairs discordant for schizophrenia offer a unique opportunity to identify factors that differ between patients and unaffected co-twins, who are perfectly matched for age, sex and genetic background.

METHODS

Register data were combined with clinical data for 216 twins including monozygotic (MZ) and dizygotic (DZ) proband pairs (one or both twins having a schizophrenia spectrum diagnosis) and MZ/DZ healthy control (HC) pairs. Logistic regression models were applied to predict (1) illness vulnerability (being a proband v. HC pair) and (2) illness status (being the patient v. unaffected co-twin). Risk factors included: A polygenic risk score (PRS) for schizophrenia, birth complications, birth weight, Apgar scores, paternal age, maternal smoking, season of birth, parental socioeconomic status, urbanicity, childhood trauma, estimated premorbid intelligence and cannabis.

RESULTS

The PRS [odds ratio (OR) 1.6 (1.1-2.3)], childhood trauma [OR 4.5 (2.3-8.8)], and regular cannabis use [OR 8.3 (2.1-32.7)] independently predicted illness vulnerability as did an interaction between childhood trauma and cannabis use [OR 0.17 (0.03-0.9)]. Only regular cannabis use predicted having a schizophrenia spectrum diagnosis between patients and unaffected co-twins [OR 3.3 (1.1-10.4)].

CONCLUSION

The findings suggest that several risk factors contribute to increasing schizophrenia spectrum vulnerability. Moreover, cannabis, a potentially completely avoidable environmental risk factor, seems to play a substantial role in schizophrenia pathology.

Recurrence of anxiety disorders and its predictors in the general population

BACKGROUND

Anxiety disorders frequently recur in clinical populations, but the risk of recurrence of anxiety disorders is largely unknown in the general population. In this study, recurrence of anxiety and its predictors were studied in a large cohort of the adult general population.

METHODS

Baseline, 3-year and 6-year follow-up data were derived from the Netherlands Mental Health Survey and Incidence Study-2 (NEMESIS-2). Respondents (N = 468) who had been in remission for at least a year prior to baseline were included. Recurrence was assessed at 3 and 6 years after baseline, using the Composite International Diagnostic Interview version 3.0. Cumulative recurrence rates were estimated using the number of years since remission of the last anxiety disorder. Furthermore, Cox regression analyses were conducted to investigate predictors of recurrence, using a broad range of putative predictors.

RESULTS

The estimated cumulative recurrence rate was 2.1% at 1 year, 6.6% at 5 years, 10.6% at 10 years, and 16.2% at 20 years. Univariate regression analyses predicted a shorter time to recurrence for several variables, of which younger age at interview, parental psychopathology, neuroticism and a current depressive disorder remained significant in the, age and gender-adjusted, multivariable regression analysis.

CONCLUSIONS

Recurrence of anxiety disorders in the general population is common and the risk of recurrence extends over a lengthy period of time. In clinical practice, alertness to recurrence, monitoring of symptoms, and quick access to health care in case of recurrence are needed.

In vivo serotonin 1A receptor hippocampal binding potential in depression and reported childhood adversity

BACKGROUND

Reported childhood adversity (CA) is associated with development of depression in adulthood and predicts a more severe course of illness. Although elevated serotonin 1A receptor (5-HT_1AR) binding potential, especially in the raphe nuclei, has been shown to be a trait associated with major depression, we did not replicate this finding in an independent sample using the partial agonist positron emission tomography tracer [¹¹C]CUMI-101. Evidence suggests that CA can induce long-lasting changes in expression of 5-HT_1AR, and thus, a history of CA may explain the disparate findings.

METHODS

Following up on our initial report, 28 unmedicated participants in a current depressive episode (bipolar n = 16, unipolar n = 12) and 19 non-depressed healthy volunteers (HVs) underwent [¹¹C]CUMI-101 imaging to quantify 5-HT_1AR binding potential. Participants in a depressive episode were stratified into mild/moderate and severe CA groups via the Childhood Trauma Questionnaire. We hypothesized higher hippocampal and raphe nuclei 5-HT_1AR with severe CA compared with mild/moderate CA and HVs.

RESULTS

There was a group-by-region effect (p = 0.011) when considering HV, depressive episode mild/moderate CA, and depressive episode severe CA groups, driven by significantly higher hippocampal 5-HT_1AR binding potential in participants in a depressive episode with severe CA relative to HVs (p = 0.019). Contrary to our hypothesis, no significant binding potential differences were detected in the raphe nuclei (p-values > 0.05).

CONCLUSIONS

With replication in larger samples, elevated hippocampal 5-HT_1AR binding potential may serve as a promising biomarker through which to investigate the neurobiological link between CA and depression.

Examining the Relationship Between Trauma, Post‐Traumatic Stress Disorder and Psychosis in Patients in a UK Secondary Care Service

Objective

Traumatic experiences and post-traumatic stress disorder (PTSD) are common in schizophrenia. However, few studies screening for PTSD have established the temporality of PTSD-related traumatic events to psychosis onset. Furthermore, it is unclear how many patients attribute a trauma-based contribution to their psychosis or would find trauma-focused therapy acceptable. We examine the prevalence and timing of trauma in psychosis, as well as patient views on the relationship between their trauma experiences and mental health difficulties, and on receiving trauma-focused therapy.

Methods

Sixty-eight patients with an at-risk mental state (ARMS) or psychotic disorder in a UK secondary-care setting completed self-report measures of trauma and PTSD, and undertook research interviews. Proportions and odds ratios were derived with 95% confidence intervals.

Results

We recruited 68 participants (estimated response rate 62%; psychotic disorder n = 61, ARMS n = 7). Sixty three (95%) reported traumatic events and 32 (47%) reported childhood abuse. Twenty-six individuals (38%) met criteria for PTSD, though for >95% this was not recorded in their notes, and 25 (37%) had sub-threshold PTSD. For 69% of participants, their worst trauma occurred before the onset of their psychosis symptoms. Most (65%) believed their psychosis symptoms were related to past traumas and 82% of these were interested in receiving trauma-focused therapy.

Conclusions

PTSD is common in and often pre-dates onset of psychosis. Most patients believe their symptoms and traumas are related and would be interested in trauma-focused therapy if available. Studies evaluating the effectiveness of trauma-focused therapies for those with or at high-risk of psychosis are required.

Childhood abuse and cortical gray matter volume in patients with major depressive disorder

Childhood abuse is associated with brain structural alterations; however, few studies have investigated the association between specific types of childhood abuse and cortical volume in patients with major depressive disorder (MDD). We aimed to investigate the association between specific types of childhood abuse and gray matter volumes in patients with MDD. Seventy-five participants with MDD and 97 healthy controls (HCs) aged 19-64 years were included. Cortical gray matter volumes were compared between MDD and HC groups, and also compared according to exposure to each type of specific childhood abuse. Emotional, sexual, and physical childhood abuse were assessed using the 28-item Childhood Trauma Questionnaire. Patients with MDD showed a significantly decreased gray matter volume in the right anterior cingulate gyrus (ACG). Childhood sexual abuse (CSA) was associated with significantly decreased gray matter volume in the right middle occipital gyrus (MOG). In the post-hoc comparison of volumes of the right ACG and MOG, MDD patients with CSA had significantly smaller volumes in the right MOG than did MDD patients without CSA or HCs. The right MOG volume decrease could be a neuroimaging marker associated with CSA and morphological changes in the brain may be involved in the pathophysiology of MDD.

The association between child maltreatment and problematic alcohol use in adulthood in a large multi-ethnic cohort: the HELIUS study

AIMS

There is evidence that child maltreatment is associated with problematic alcohol use later in life. However, previous epidemiological studies that have examined the link between child maltreatment and adult problematic alcohol use have not considered ethnic differences. Therefore, the purpose of the current study was to investigate the relationship between child maltreatment and adult problematic alcohol use among six ethnic groups in the Netherlands, in a large, urban sample.

METHODS

This study used baseline data from the Healthy Life in an Urban Setting (HELIUS) study: a large-scale, multi-ethnic prospective cohort study conducted in Amsterdam, the Netherlands. Child maltreatment, current problematic alcohol use and several potential confounders (e.g. parental alcohol use) were assessed in participants (N = 23 356) of Dutch, South-Asian Surinamese, African Surinamese, Ghanaian, Turkish and Moroccan origin. With logistic regression analyses, we examined effect modification by ethnicity on the association between child maltreatment and problematic alcohol use. Furthermore, we explored effect modification by ethnicity for specific types of child maltreatment, namely: physical, sexual and psychological abuse and emotional neglect.

RESULTS

Effect modification by ethnicity was present. Stronger associations between child maltreatment and problematic alcohol use were found in all ethnic minority groups compared to the Dutch reference group. Particularly strong associations between all four types of child maltreatment and alcohol use problems were found for the Moroccan origin group.

CONCLUSIONS

This study adds to a growing body of evidence that child maltreatment is associated with problematic alcohol use in adulthood. In addition, our findings indicate that ethnicity impacts this relationship. Although problematic alcohol use was more prevalent in the Dutch origin group, associations with child maltreatment were stronger in ethnic minority groups. Future studies on child maltreatment and alcohol use problems should also examine ethnic disparities and should further unravel how these disparities can be explained.

Aberrant static and dynamic functional connectivity of amygdala subregions in patients with major depressive disorder and childhood maltreatment

Major depressive disorder (MDD) with childhood maltreatment is a heterogeneous clinical phenotype of depression with prominent features of brain disconnectivity in areas linked to maltreatment-related emotion processing (e.g., the amygdala). However, static and dynamic alterations of functional connectivity in amygdala subregions have not been investigated in MDD with childhood maltreatment. Here, we explored whether amygdala subregions (i.e., medial amygdala [MeA] and lateral amygdala [LA]) exhibited static functional connectivity (sFC) and dynamic functional connectivity (dFC) disruption, and whether these disruptions were related to childhood maltreatment. We compared sFC and dFC patterns in MDD with childhood maltreatment (n = 48), MDD without childhood maltreatment (n = 30), healthy controls with childhood maltreatment (n = 57), and healthy controls without childhood maltreatment (n = 46). The bilateral MeA and LA were selected as the seeds in the FC analysis. The results revealed a functional connectivity disruption pattern in maltreated MDD patients, characterized by sFC and dFC abnormalities involving the MeA, LA, and theory of mind-related brain areas including the middle occipital area, middle frontal gyrus, superior medial frontal gyrus, angular gyrus, supplementary motor areas, middle temporal gyrus, middle cingulate gyrus, and calcarine gyrus. Significant correlations were detected between impaired dFC patterns and childhood maltreatment. Furthermore, the dFC disruption pattern served as a moderator in the relationship between sexual abuse and depression severity. Our findings revealed neurobiological features of childhood maltreatment, providing new evidence regarding vulnerability to psychiatric disorders.

An in-depth look at latent classes of DSM-5 psychiatric comorbidity among individuals with PTSD: Clinical indicators and treatment utilization

OBJECTIVE

Posttraumatic stress disorder (PTSD) is associated with high comorbidity rates across the full range of psychiatric disorders. However, little is known about how psychiatric comorbidity manifests among people with PTSD, particularly with regard to concurrent diagnoses.

METHOD

Latent class analysis (LCA) was used to characterize discrete classes of PTSD comorbidity using past year DSM-5 diagnostic standards among a large nationally representative epidemiologic sample of U.S. adults. Follow-up analyses compared participant characteristics across latent classes.

RESULTS

The LCA was best characterized by five classes: low comorbidity, distress-fear, distress-externalizing, mania-fear-externalizing, and mania-externalizing. Excluding the low comorbidity class, proportions of borderline and schizotypal personality disorder were high across classes.

CONCLUSION

Participant characteristics across classes of past year PTSD comorbidity are explored through the lens of case conceptualization and treatment planning utility.

Childhood trauma and LPS-stimulated inflammation in adulthood: Results from the Netherlands Study of Depression and Anxiety

BACKGROUND

Childhood trauma (CT) is robustly associated with psychiatric disorders including major depressive and anxiety disorders across the life span. The innate immune system may play a role in the relation between CT and stress-related psychopathology. However, whether CT influences the innate production capacity of cytokine levels following ex vivo stimulation by lipopolysaccharide (LPS), is currently unknown.

METHODS

Using data from the Netherlands Study of Depression and Anxiety (NESDA, n=1237), we examined whether CT (emotional neglect, emotional, physical, and sexual abuse before the age of 16), assessed by the Childhood Trauma Interview, was associated with levels in supernatants of interferon (IFN)γ, interleukin-2 (IL-2), IL-4, IL-6, IL-8, IL-10, IL-18, monocyte chemotactic protein-1 (MCP-1), macrophage inflammatory protein (MIP)-1α, MIP-1β, matrix metalloproteinase-2 (MMP-2), TNFα and TNFβ after ex vivo stimulation with LPS. Cytokines were analysed individually and cumulatively (overall inflammation index and number of cytokines in high-risk quartile (HRQ)) using linear regression analyses.

RESULTS

After adjustment for demographic, lifestyle, and health-related covariates, total CT severity was associated with the overall inflammation index (β = 0.085, P_FDR = 0.011), the number of cytokines in HRQ (β = 0.063, P_FDR = 0.036), and individual markers of IL-2 (β = 0.067, P_FDR = 0.036), IL-6 (β = 0.091 P_FDR = 0.011), IL-8 (β = 0.085 P_FDR = 0.011), IL-10 (β = 0.094 P_FDR = 0.011), MCP-1 (β = 0.081 P_FDR = 0.011), MIP-1α (β = 0.061 P_FDR = 0.047), MIP1-β (β = 0.077 P_FDR = 0.016), MMP-2 (β = 0.070 P_FDR = 0.027), and TNFβ (β = 0.078 P_FDR = 0.016). Associations were strongest for individuals with severe CT, reporting multiple types or higher frequencies of trauma. Half of the findings persisted after adjustment for psychiatric status. The findings were consistent across different CT types.

CONCLUSION

Childhood Trauma is associated with increased LPS-stimulated cytokine levels, with evidence for a dose-response relationship. Our results highlight a dysregulated innate immune system capacity in adults with CT, which could contribute to an increased vulnerability for psychopathology and somatic disorders across the lifespan.

Feasibility of Screening Programs for Domestic Violence in Pediatric and Child and Adolescent Mental Health Services: A Literature Review

Each year, 275 million children worldwide are exposed to domestic violence (DV) and suffer negative mental and physical health consequences; however, only a small proportion receive assistance. Pediatricians and child psychiatrists can play a central role in identifying threatened children. We reviewed experiences of DV screening in pediatric and child and adolescent mental health services (CAMHS) to understand its feasibility and provide clues for its implementation. We performed bibliographic research using the Sapienza Library System, PubMed, and the following databases: MEDLINE, American Psychological Association PsycArticles, American Psychological Association PsycInfo, ScienceDirect, and Scopus. We considered a 20-year interval when selecting the articles and we included studies published in English between January 2000 and March 2021. A total of 23 out of 2335 studies satisfied the inclusion criteria. We found that the prevalence of disclosed DV ranged from 4.2% to 48%, with most prevalence estimates between 10% and 20%. Disclosure increases with a detection plan, which is mostly welcomed by mothers (70–80% acceptance rates). Written tools were used in 55% of studies, oral interviews in 40%, and computer instruments in 20%. Mixed forms were used in three studies (15%). The most used and effective tool appeared to be the Conflict Tactics Scale (CTS) (30% of studies). For young children, parental reports are advisable and written instruments are the first preference; interviews can be conducted with older children. Our research pointed out that the current literature does not provide practical clinical clues on facilitating the disclosure in pediatric clinics and CAMHS. Further studies are needed on the inpatient population and in the field of children psychiatry.

Childhood trauma and its impact on depressive and anxiety symptomatology in adulthood: A 6-year longitudinal study

BACKGROUND

Childhood trauma (CT) is a risk factor for depressive and anxiety disorders. However, whether CT is more strongly linked to specific clinical features of these disorders remains inconclusive. The current study comprehensively examined cross-sectional and longitudinal associations between CT and depressive/anxiety symptomatology in a large adult sample with current and remitted depressive and/or anxiety disorders.

METHODS

Baseline (n = 1803), 2-year (n = 1735), 4-year (n = 1585), and 6-year follow-up (n = 1475) data from the Netherlands Study of Depression and Anxiety were used. CT (emotional neglect, emotional/physical/sexual abuse) was assessed at baseline, while depressive/anxiety symptomatology with relevant dimensions (e.g., mood/cognitive, melancholic, general distress, and somatic depression) was assessed at each wave using self-reported questionnaires. Linear regressions and linear mixed models determined cross-sectional and longitudinal associations.

RESULTS

Individuals with CT, especially, severe CT, compared to those without CT, had significantly higher scores in overall depressive symptomatology (Cohen's d = 0.674), mood/cognitive depression (d = 0.691), melancholic depression (d = 0.587), general distress (d = 0.561), and somatic depression severity (d = 0.549). Differences were lower, but still highly significant for anxiety (d = 0.418), worry (d = 0.362), and fear/phobic symptomatology (d = 0.359). Effects were consistent across CT types and maintained over six years.

LIMITATIONS

Retrospectively-reported CT.

CONCLUSIONS

CT is a risk factor for depressive and anxiety symptomatology across all dimensions and enduring over multiple years. Screening for CT is essential to identify individuals at risk for more severe and chronic manifestations of affective disorders.

How psychosocial stress profile influences the subsequent occurrence of neuropsychiatric comorbidities: A longitudinal population-based cohort study

BACKGROUND

The role of psychosocial stressors in psychiatric disorders and executive dysfunction has been reported, separately. The literature has also suggested the involvement of social support and coping strategies in these relationships. However, there is a lack of research conducted to examine the relationships among multiple stressors and neuropsychiatric comorbidities while considering the presence of social support and coping strategies. This study aims to articulate the roles of multiple psychosocial stressors, social support, and coping strategies in the subsequent occurrence of neuropsychiatric comorbidities.

METHODS

Data analyzed were from the 6th data collection of a large-scale, longitudinal population-based cohort from Southwest Montreal in Canada. The cumulative effects of multiple stressors were separately examined by a composite score and latent profile analysis. Multinomial logistic regression models were used to test the relationship between cumulative stressors and neuropsychiatric comorbidities.

RESULTS

A total of 210 participants were included in the analyses. The LPA identified a 2-class model for psychosocial stressors (low and high) and executive function (executive dysfunction and no executive dysfunction), respectively. There were 11.8% of participants with neuropsychiatric comorbidities. Both the composite stress score (RR = 1.08, 95%CI = 1.01-1.15) and latent stress groups (RR = 3.65, 95%CI = 1.15-11.57) were associated with neuropsychiatric comorbidities after adjusting for social support and coping strategies. The risk of developing neuropsychiatric comorbidities decreased when the level of social support was high (P < 0.05).

CONCLUSIONS

Exposures to multiple stressors increased the risk of subsequent neuropsychiatric comorbidities, but the risk can be modified by a higher level of social support.

Aberrant brain connectivity is associated with childhood maltreatment in individuals with major depressive disorder

Although childhood maltreatment confers a high risk for the development of major depressive disorder, the neurobiological mechanisms underlying this connection remain unknown. The present study sought to identify the specific resting-state networks associated with childhood maltreatment. We recruited major depressive disorder patients with and without a history of childhood maltreatment (n = 31 and n = 30, respectively) and healthy subjects (n = 80). We used independent component analysis to compute inter- and intra- network connectivity. We found that individuals with major depressive disorder and childhood maltreatment could be characterized by the following network disconnectivity model relative to healthy subjects: (i) decreased intra-network connectivity in the left frontoparietal network and increased intra-network connectivity in the right frontoparietal network, (ii) decreased inter-network connectivity in the posterior default mode network-auditory network, posterior default mode network-limbic system, posterior default mode network-anterior default mode network, auditory network-medial visual network, lateral visual network - medial visual network, medial visual network-sensorimotor network, medial visual network - anterior default mode network, occipital pole visual network-dorsal attention network, and posterior default mode network-anterior default mode network, and (iii) increased inter-network connectivity in the sensorimotor network-ventral attention network, and dorsal attention network-ventral attention network. Moreover, we found significant correlations between the severity of childhood maltreatment and the intra-network connectivity of the frontoparietal network. Our study demonstrated that childhood maltreatment is integrally associated with aberrant network architecture in patients with major depressive disorder.
