Evidence for psychological risk factors on prodromal state of psychosis remained limited and inconsistent. This study aimed to investigate childhood trauma, life events and social support in subjects with high risk for psychosis (HR), first episode psychosis with schizophrenia (FEP) and healthy control (HC). In the study, 56 FEP, 83 HR and 61 HC underwent face-to-face clinical interview and psychological assessment, including Childhood Trauma Questionnaire (CTQ), Life Events Scale (LES) and Perceived Social Support Scale (PSSS). The results showed that in univariate analysis, HR individuals had more childhood trauma, more recent life events and less social support than HC group, and these findings were also supported by ANCOVA analysis except for the results related to social support after taking age, education, marital and employment status as covariates. Logistic regression analysis revealed that HR group was significantly associated with more childhood trauma, poorer overall function and unmarried state than HC group after controlling the interfering factors. HR group was similar with FEP group in these assessments. In conclusion, HR individuals experienced more childhood trauma, life events and social support deficit than HC group, which may be risk factors of conversion to psychosis. Further explorations are warranted to develop optimal psychosocial interventions.

Background: Severe or recurring major depression is associated with increased adverse childhood experiences (ACEs), heightened atherogenicity, and immune-linked neurotoxicity (INT). Nevertheless, the interconnections among these variables in outpatient major depression (OMDD) have yet to be determined. We aim to determine the correlations among INT, atherogenicity, and ACEs in OMDD patients compared to normal controls.

Introduction: PAdverse Childhood Experiences (ACEs) are associated with an increased risk of mental health issues in general, but their relationship with panic disorder (PD) and obsessive-compulsive disorder (OCD) has received less attention compared to borderline personality disorder (BPD). Dissociative experiences are significant predictors of increased symptoms, reduced treatment adherence, and poor prognosis in several psychiatric conditions, including PD, OCD, and BPD; still, their impact remains underexplored. This part of the study focuses on the overall efficiency of psychotherapeutic programs on treatment-resistant patients diagnosed with PD, OCD, and BPD (or combined), as well as the relationship between ACEs, dissociation rates, and treatment results.

Introduction: Panic disorder (PD), obsessive-compulsive disorder (OCD), and borderline personality disorder (BPD) are associated with various psychosocial factors that may influence their onset and psychopathology. Dissociation encompasses a wide range of manifestations, from benign experiences to severe mental health issues. Research comparing childhood trauma and dissociation, general psychopathology, and the onset of the disorder among patients with PD, OCD, and BPD has not yet been published.

Background: Accumulating literature has found a close relation between early life adversity (ELA) and anxiety. However, previous studies did not rule out the high co-occurrence of different types of ELA when exploring the association of ELA and anxiety. In the present study, we carried out network analysis based on a cross-sectional sample and longitudinal sample to investigate the relationship between ELA and anxiety symptoms in non-clinical populations over time.

The current study examined whether adverse childhood experiences and racial discrimination predicted adolescents' internal developmental assets, external developmental assets, and depressive symptoms. We also tested whether these relations were buffered by aspects of caregivers' reports of ethnic-racial socialization efforts (i.e.
