Childhood trauma (CT) and parental bonding (PB) have been correlated with later antisocial personality disorder (ASPD). Aiming to better understand this complex interaction we analyzed the data from a cross-sectional study that evaluated 346 male inpatient cocaine users, using both traditional statistical analysis and machine learning (ML) approaches. Childhood Trauma Questionnaire (CTQ), Parental Bonding Instrument (PBI), and Mini International Neuropsychiatric Interview (MINI) were applied. We found a markedly higher prevalence of mental illness in the ASPD group. The ML method and the traditional analysis showed that emotional and physical abuse were the factors with the strongest relationship with ASPD. Also, there were discrepancies between the findings of both methods regarding physical neglect and paternal care. Although this study does not allow definitive answers in this matter, we do propose that these two methods can aid in better comprehending how multiple variables interact with each other in the development of psychological disorders.

The Democratic Republic of the Congo (DRC) struggles with low full childhood vaccination coverage (around 50 %) and a high children-under-five mortality rate (79 deaths per 1000 live births). This situation is potentially exacerbated by vaccine hesitancy, which was identified by the World Health Organization (WHO) as one of the top 10 global health threats in 2019. To gain deeper insights into levels of vaccine confidence possibly influencing vaccination coverage, we explored perceptions and attitudes towards childhood and adult vaccines in Boende (Tshuapa province, western DRC), which experienced an Ebola outbreak in 2014 and hosted the EBL2007 Ebola vaccine trial (2019-2022).

The present study utilized a sample of 374 distressed couples seeking therapy to investigate: (1) how partners' adverse childhood experiences (ACEs) and shared religious/spiritual (R/S) practices are associated with their relationship satisfaction at intake and (2) the rate and shape of change in relationship satisfaction over the first six sessions. The results from multilevel modeling (MLM) demonstrated that males' ACEs were negatively associated with both their own and their partners' relationship satisfaction at intake, whereas females' ACEs were negatively associated only with their own satisfaction, not their partners'. Regarding shared R/S practices, only females' reports were positively associated with both their own and their partners' satisfaction at intake; no effects were observed for males' reports.

Background: Childhood trauma (CT) is related to altered fractional anisotropy (FA) in individuals with schizophrenia (SZ). However, it remains unclear whether CT may influence specific cellular or extracellular compartments of FA in SZ with CT experience. We extended our previous study on FA in SZ (Costello et al.

Given the significant prevalence of adverse childhood experiences (ACEs) and their detrimental impact on mental health, this study examines the relationship between attachment anxiety, attachment avoidance, and complex post-traumatic stress disorder (CPTSD) among college students with ACEs, emphasizing the mediating role of self-compassion (SC). A sample of 32,388 students from Kunming, China completed a survey including the Revised Adverse Childhood Experiences Questionnaire (ACEQ-R), the Adult Attachment Scale (AAS), the International Trauma Questionnaire (ITQ), and the Self-Compassion Scale-Short Form (SCS-SF). Among the participants, 3,896 reported at least one ACE.

Background: Adverse childhood experiences (ACEs) may increase the risk for adolescent sleep disturbances, though the impact of race, ethnicity, and socioeconomic status (SES) remains unclear.

Objective: We sought to determine the direct and moderating impact of race, ethnicity, family SES, and community SES on sleep disturbances across early adolescence for ACE-exposed youth.

Participants And Setting: This secondary analysis used longitudinal Adolescent Brain Cognitive Development Study® data (2016-2022) from youth who experienced ≥1 ACE by age 9-10 years.
