Intergenerational Trauma: Assessment in Biological Mothers and Preschool Children

The Impact of Maternal Childhood Trauma on Children's Problem Behaviors: The Mediating Role of Maternal Depression and the Moderating Role of Mindful Parenting

Objective

This study investigates the impact of maternal childhood trauma on children's problem behaviors, focusing on the mediating role of maternal depression and the moderating role of mindful parenting.

Methods

The study used a convenience sampling method to survey 385 mother-child pairs from kindergartens in Jinan, China. Data were collected in two waves, and various validated questionnaires were used to assess maternal childhood trauma, depression, mindful parenting, and children's problem behaviors.

Results

Maternal childhood trauma positively predicted children's problem behaviors. Maternal depression was found to mediate this relationship. Mindful parenting moderated the effects of maternal childhood trauma and depression on children's problem behaviors, with high levels of mindful parenting mitigating these adverse effects.

Conclusion

Maternal childhood trauma impacts children's problem behaviors both directly and indirectly through maternal depression. Mindful parenting serves as a protective factor, reducing the negative impact of maternal childhood trauma and depression on children's problem behaviors. These findings highlight the importance of interventions aimed at enhancing mindful parenting practices to improve child outcomes.

Maternal insecure attachment representation as a long-term risk factor for disrupted mother-child-interaction and child mental health

Maternal childhood maltreatment (CM) represents an important factor in the transmission of trauma that may lead to impaired child mental health. Apart from childhood maltreatment insecure attachment has been identified as a risk factor for insensitive caregiving behavior, which may affect child's mental health. The aim of this study is to identify the working mechanisms in the relationship between maternal CM and child mental health, considering maternal attachment representation, mother-child-interaction und maternal helplessness and fear. N = 103 mother-child-dyads from a longitudinal cohort study were examined at four different measuring points. Data was assessed using self and external report questionnaires as well as the AMBIANCE scales during the Strange Situation Procedure and the Adult Attachment Projective Picture System (AAP). Maternal CM experience did not predict an insecure attachment representation (OR = 2.46 [0.98, 6.53], p = .060). Maternal insecure attachment was associated with higher AMBIANCE scores (F(8, 94) = 11.46, p < .001), which indicates more disrupted communication between mother and child. AMBIANCE scores in turn predicted higher self-perceived helplessness (F(9, 93) = 8.62, p < .001) and fear (F(9, 93) = 7.40, p < .001) in mothers. Helplessness and fear both were associated with higher SDQ-scores, indicating more mental health problems in children (F(10, 92) = 3.98, p < .001; F(10, 92) = 3.87, p < .001). The results of this study highlight how even insecure attachment in a low-risk sample has a long-term impact on parenting behavior and child mental health, therefore underlining the need of early intervention programs in affected and at-risk families.

Neurobiological Alterations in Females With PTSD: A Systematic Review

Most females experience at least one traumatic event in their lives, but not all develop PTSD. Despite considerable research, our understanding of the key factors that constitute risk for PTSD among females is limited. Previous research has largely focused on sex differences, neglecting within group comparisons, thereby obviating differences between females who do and do not develop PTSD following exposure to trauma. In this systematic review, we conducted a search for the extent of existing research utilizing magnetic resonance imaging (MRI) to examine neurobiological differences among females of all ages, with and without PTSD. Only studies of females who met full diagnostic criteria for PTSD were included. Fifty-six studies were selected and reviewed. We synthesized here findings from structural MRI (sMRI), functional MRI (fMRI), diffusion tensor imaging (DTI), and resting state functional connectivity (rs-FC MRI) studies, comparing females with and without PTSD. A range of biopsychosocial constructs that may leave females vulnerable to PTSD were discussed. First, the ways timing and type of exposure to trauma may impact PTSD risk were discussed. Second, the key role that cognitive and behavioral mechanisms may play in PTSD was described, including rumination, and deficient fear extinction. Third, the role of specific symptom patterns and common comorbidities in female-specific PTSD was described, as well as sex-specific implications on treatment and parenting outcomes. We concluded by identifying areas for future research, to address the need to better understand developmental aspects of brain alterations, the differential impact of trauma types and timing, the putative role of neuroendocrine system in neurobiology of PTSD among females, and the impact of social and cultural factors on neurobiology in females with PTSD.
