•The risk of physical violence is significantly higher in patients with schizophrenia compared to the general population.•Several biological, psychological, and socioeconomic features have been ...identified as risk factors for violence.•We formulated a predictive model that significantly predicts certain violence trajectories in schizophrenia based on sex and stressful life events.
The risk of violence is higher in schizophrenia spectrum disorders (SSD) compared to the general population and it is a pressing and understudied issue. Several dispositional and environmental factors have been previously correlated with violence, however, there has been little success in assessing their ability to predict violence patterns across the life span. This study aims to assess violence prediction based on personality traits, psychological resilience, and life-course adversities in a non-forensic population of SSD patients. In a sample of 231 patients with SSD, we assessed violence using the Brown-Goodwin History of Lifetime Aggression Scale and conducted cross-sectional assessments of possible predictors such as childhood trauma, personality traits and resilience scores. We then utilized a logistic regression classification algorithm to predict different violence trajectories based on the proposed risk factors. Our model significantly predicted individuals with violence in both childhood and adulthood, as well as childhood-only violence (p < 0.001). However, the model did not show significance for adult-only violence (p = 0.604). In all given trajectories, female sex appeared to be protective against violence, while stressful life events appeared to contribute to it. These results suggest that distinct factors can better inform risk assessment of lifespan violence patterns for personalized interventions in SSD.
Evidence suggests that dissociation is associated with psychotic experiences, particularly hallucinations, but also other symptoms. However, until now, symptom-specific relationships with ...dissociation have not been comprehensively synthesized. This is the first prospectively registered (CRD42017058214) meta-analysis to quantify the magnitude of association between dissociative experiences and all symptoms of psychosis. MEDLINE, PsycINFO, PubMed, and Scopus databases were searched using exhaustive terms denoting dissociation and psychotic symptoms. We included both nonclinical (58 studies; 16 557 participants) and clinical (46 studies; 3879 patient participants) samples and evaluated study quality. Ninety-three eligible articles considering 20 436 participants were retained for analysis. There was a robust association between dissociation and clinical and nonclinical positive psychotic symptoms (r = .437; 95%CI: .386 -.486), with the observed effect larger in nonclinical studies. Symptom-specific associations were also evident across clinical and nonclinical studies, and included significant summary effects for hallucinations (r = .461; 95%CI: .386 -.531), delusions (r = .418; 95%CI: .370 -.464), paranoia (r = .447; 95%CI: .393 -.499), and disorganization (r = .346; 95%CI: .249 -.436). Associations with negative symptoms were small and, in some cases, not significant. Overall, these findings confirm that dissociative phenomena are not only robustly related to hallucinations but also to multiple positive symptoms, and less robustly related to negative symptoms. Our findings are consistent with proposals that suggest certain psychotic symptoms might be better conceptualized as dissociative in nature and support the development of interventions targeting dissociation in formulating and treating psychotic experiences.
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.
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).
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.
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.
•There was a significant effect of diagnostic group on mean level of total borderline personality features. The highest number of borderline personality features was observed within the participants with bipolar disorder followed by major depressive disorder recurrent, and finally major depressive disorder single episode.•The order bipolar disorder > major depressive disorder recurrent > major depressive disorder single episode was observed for all four main domains of borderline personality disorder (affective instability, identity problems, negative relationship & self-harm).•Within each diagnostic category, participants with a history of childhood trauma consistently showed higher average scores for borderline personality features.•Emotional neglect was the most strongly associated factor, with both the total number of borderline personality features and its four main subscale scores

Early life events can have long-lasting effects that may impact the quality of life into adulthood. The link between childhood adversities and adult mental and physical health is well documented, however, the underlying mechanisms remain poorly understood. Executive functions are assumed to be a key factor in successfully dealing with cognitive-emotional challenges thereby contributing to stress resilience and mental health across the lifespan. Here, we examined whether cognitive control moderates the link between early life adversity and depression. Data was available from a sample of 424 participants aged 20–70 years (Clinicaltrials.gov: NCT05155397). They performed in the Stroop task and behavior as well as frontal theta power were recorded. Negative childhood experiences were assessed with the Childhood Trauma Questionnaire (CTQ), chronic stress was measured with the Trier Inventory for Chronic Stress (TICS) and depression symptoms with Beck’s Depression Inventory (BDI). The CTQ predicted symptoms of chronic stress and depression. Regression models pointed to the TICS as a crucial mediator in the relationship between CTQ and BDI. However, parameters of cognitive control demonstrated a rather weak effect as moderators. These results indicate that chronic stress is an important mediator linking childhood trauma to depression but suggest only a limited role for cognitive control.
Childhood trauma is any traumatic experience that occurs before the age of 18. The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a popular questionnaire for childhood trauma. The present ...study aimed to examine the reliability and validity of the Japanese translated version of CTQ-SF (CTQ-JNIMH) in Japanese adults. The present study included two types of participants: nonclinical (n = 762) and clinical (n = 111). Most of the clinical participants were diagnosed with posttraumatic stress disorder. A two-wave online survey was conducted with the nonclinical participants, and a face-to-face cross-sectional survey was conducted with the clinical participants. As a result, confirmatory factor analysis suggested that the factor structure of the CTQ-JNIMH in this study was identical to that of the original. Each subscale had an acceptable level of internal consistency and test-retest reliability, except for physical neglect. Convergent validity was confirmed for all the subscales of CTQ-JNIMH. The scores of clinical participants were significantly higher than those of nonclinical participants in all subscales of the CTQ-JNIMH; substantial differences were found in emotional abuse, physical abuse, and sexual abuse based on the effect sizes. These findings supported the reliability and validity of the CTQ-JNIMH in both clinical and nonclinical Japanese adults.
•The factor structure was identical to the original.•Acceptable levels of reliability and validity were confirmed.
Introduction: Considering the high prevalence and negative effects of borderline personality disorders, it is important to know as much as possible about this disorder and to identify the predictors ...and variables of this disorder. Aim: The present study was Mediating role of experiential avoidance in predicting borderline personality disorder based on childhood trauma. Method: The present study was a correlational description. The statistical population included all male patients diagnosed with borderline personality disorder admitted to psychiatric hospitals in Shiraz in 2022, which were selected using targeted sampling of 60 people. Data collection was done using the childhood trauma questionnaire (2003), the experiential avoidance questionnaire (2011) and the short scale of borderline personality disorder symptoms (2009). To analyze the data, path analysis test, structural equations and Smart PLS software were used. Results: The findings showed that there is a significant and positive relationship between childhood trauma and experiential avoidance (R2=0.711; p<0.05). Path analysis findings also showed that childhood trauma plays a significant role in predicting borderline personality disorder (path coefficient 0.546) and also the avoidance of experience plays a mediating role in the relationship between childhood trauma and borderline personality disorder, so that the path coefficient is 304. 0/ has shown a significant decrease (p<0.05). Conclusion: The results showed that experiential avoidance has a mediating role in predicting borderline personality disorder based on childhood trauma, so it is necessary to pay attention to the component of childhood trauma along with attention to experiential avoidance as a model to reduce the severity of psychological complications.
•The prevalence of childhood maltreatment ranged 0.31-0.38 depending on subtype.•Substance use disorder samples reported almost one third of people with single types of maltreatments.•Childhood ...maltreatment rates vary between different continents and are more commonly in North America.
Substance use disorder is known to be associated with childhood trauma, yet prevalence estimates have varied markedly due to methodological differences. The meta-analysis presented here aimed to estimate prevalence rates of childhood trauma for people with substance use disorder using the short form of the Childhood Trauma Questionnaire (CTQ-SF).
Four major public databases (PubMed, Embase, The Cochrane Library and PsycINFO) were searched for eligible studies until April 2nd, 2018.
Ten studies were included with a total sample size of 1,310 across six countries. The prevalence estimates of each subtype of childhood trauma across all substance use disorder samples were: emotional abuse (38%, 95% CI: 28%-48%); physical abuse (36%, 95% CI: 27%-45%); sexual abuse (31%, 95% CI: 23%-41%); emotional neglect (31%, 95% CI: 18%-45%) and physical neglect (32%, 95% CI: 25%-40%). Subgroup analysis by continent demonstrated that the highest prevalence rates of emotional abuse were found in North America and South America (45%). Compared with other continents, the prevalence rates of North America were the highest for physical abuse, sexual abuse, emotional neglect and physical neglect (39%-44%).
Childhood trauma is prevalent among substance use disorder samples compared to the general population. Different continents have different levels of prevalence of childhood trauma, which may be due in part to socioeconomic, cultural and definitional variations.
This paper reviews and discusses the literature on childhood trauma (CT) in people with first-episode psychosis (FEP). The aim is to update the knowledge on the prevalence and the types of CT ...suffered by FEP people, to compare them with other samples, to study the impact of gender, and to examine the relationship between CT and symptoms and functional outcomes. We conducted a literature search (1995–2019), to identify reported data on any topic related to CT in FEP samples. The following terms were used in the search: CT or sexual abuse or physical abuse or neglect, and first-episode psychosis. We found 493 studies, of which 68 were included in the review. FEP presented a higher prevalence of CT than controls. Women suffer more sexual abuse. The effect of CT on the severity, the prognosis and the evolution of FEP is unclear. FEP have a high prevalence of CT. Its relationship with symptoms and functional outcomes indicates its importance within treatment. This suggests the importance of creating and implementing specific interventions and personalized therapies addressed to work through their past traumatic experiences to improve their quality of live and their prognosis.
Childhood trauma has been associated with substance use disorders (SUDs), but less research has investigated its association with food addiction (i.e., compulsive intake of highly processed foods ...containing refined carbohydrates and/or added fat). Existing research on childhood trauma and food addiction has focused primarily on women from restricted samples. Further, emotion dysregulation difficulties are implicated in both childhood trauma and food addiction, but research has not explored whether it may play a mediating role.
The current study utilizes a sample of 310 participants recruited from Amazon Mechanical Turk (mean age = 41.3 years old, 47.4% men, 78.7% white) to investigate the mediating role of emotion dysregulation in the association between childhood trauma and food addiction. We also conducted exploratory analyses to investigate for gender differences in these associations. Gender-stratified correlational matrixes were conducted to investigate associations between childhood trauma, food addiction, and emotional dysregulation. Moderated mediation models and multilevel regressions were also conducted to identify the role of gender in the association between childhood trauma, food addiction, and emotion dysregulation.
Emotion dysregulation was found to partially mediate the associations between food addiction and childhood trauma and gender was found to moderate associations between childhood trauma and emotion dysregulation, as well as childhood trauma and food addiction. Both moderating pathways were significantly stronger for men compared to women.
Results suggests that emotion dysregulation may be one important mediator in the association between childhood trauma and food addiction, particularly for men. The identification of other potential mechanisms contributing to the association between childhood trauma and food addiction and the use of longitudinal measurement strategies will be important in future research.
