QEEG and LORETA findings in children with histories of relational trauma. (open access)

QEEG and LORETA findings in children with histories of relational trauma.

Abuse and neglect occurring in childhood have been associated with a number of functional and physiological effects on the brain. This study extends previous research that investigated the quantitative electroencephalogram (qEEG) patterns in children with histories of relational trauma through the inclusion of additional participants and measures. As in previous studies, the relative power, absolute power, and coherence values in children with histories of abuse were compared to the Neuroguide database. Results did not show any significant differences in relative or absolute power in the theta range. Similarly, there were no significant coherence differences. Database comparisons were also made using low resolution electromagnetic tomography (LORETA) in order to determine which sub-cortical brain structures may be affected by abuse or trauma, though there were no significant differences in any frequency (0-30Hz). A review of the literature suggests that the prevalence of mu in normal adults and children ranges from 0 to 19%. The present study found a mu prevalence rate of 60.6% in the children who experienced abuse or neglect. Finally, comparisons were made between participants who demonstrate a mu pattern and those who do not to determine if this pattern is associated with certain behavioral and/or attention problems as assessed …

The Determinants and Consequences of Empathic Parenting: Testing an Expansion of Belsky's Model of Parenting Using SEM (open access)

The Determinants and Consequences of Empathic Parenting: Testing an Expansion of Belsky's Model of Parenting Using SEM

An understanding of factors that enhance empathic parenting behaviors is of considerable importance to the study of child development and to the development of parenting interventions to promote child adjustment. Moreover, gaining a better understanding of the factors that predict empathic parenting with older children is of interest since most research examining parental empathy focuses on infants. These were the goals of the current study. Guided by Belsky's 1984 process model of the determinants of parenting that impact child development, an expanded model of the determinants of parenting is proposed that includes various parent, child, and contextual factors of influence. Using data from a community sample, a partial least squares path analysis approach was employed to test the model's strength in predicting empathically attuned parenting with children ages 5 to 10 years and, ultimately, the child's psychoemotional functioning. Results support the expanded model; however, a reduced model was found to be superior and revealed unique relationships between the determinants of parenting. Specifically, a parent's psychoemotional functioning and childrearing beliefs and attitudes were found to be critical to the parent's ability to engage in empathic parenting behaviors. Other parent factors such as the parent's developmental history of abuse, maladaptive personality traits, …
