The link between childhood harsh parenting and later aggression is well established. However, harsh parenting may occur within the context of nonviolent discipline. Moreover, sympathetic nervous system activity may moderate the effects of harsh parenting on aggression. This study examined whether sympathetic nervous system activity, measured by skin conductance level (SCL), and childhood nonviolent discipline moderate the link between childhood harsh parenting and later aggression among emerging adults. Participants (N = 264, mean age = 19.37, 54% females) reported retrospectively on experiences of childhood harsh parenting and nonviolent discipline as well as current anger, hostility, verbal, and physical aggression. We also measured resting SCL. Regression analyses revealed a significant three-way interaction between childhood harsh parenting, nonviolent discipline, and resting SCL accounting for anger and a significant two-way interaction between childhood harsh parenting and resting SCL accounting for hostility. Results suggested that (1) at high levels of resting SCL and low levels of childhood nonviolent discipline and (2) at low levels of resting SCL and high levels of childhood nonviolent discipline, the link between childhood harsh parenting and anger was stronger. Moreover, the association between childhood harsh parenting and hostility was stronger among participants who exhibited high resting SCL. The findings are consistent with the biological sensitivity to context theory. Our study highlighted the importance to examine the influence of both environmental and biological variables underlying emerging adults' aggression. [ABSTRACT FROM AUTHOR]

There has been an increased recognition that validity testing is an integral component of evaluations conducted with youth. The incorporation of validity testing provides an objective basis for placing confidence in the test data as an accurate assessment of the child's or adolescent's current ability level and/or an accurate indication of the child's or adolescent's current symptoms or behavioral functioning. The use of objective performance validity and symptom validity is consistent with the current emphasis of data-driven decision-making. This paper provides a review of the literature on performance and symptom validity tests for children and adolescents. The strengths and limitations of the available validity tests are discussed, and recommendations for use in pediatric assessments are provided. [ABSTRACT FROM AUTHOR]

Recent research efforts have focused on examining the relationship between environmental and physiological factors to better understand the effect that childhood chronic stress might have on adult health outcomes. This study examines the relation between childhood parental aggression exposure and the sympathetic nervous system (SNS), as measured by resting skin conductance levels (SCLs). Participants (N = 155) completed retrospective self-report measures of childhood exposure to interparental aggression and physically aggressive parenting. The 2-way interaction between exposure to physically aggressive parenting and interparental aggression accounted for unique variance in adulthood SCL. Sex differences emerged in this relationship. Results suggest that the type of aggression exposure might play an important role in the relationship between stressors in youth and resting SNS activity in adulthood. Future research areas are identified, including the need to examine plasticity in the SNS depending on the age of experienced aggression and the age of intervention. [ABSTRACT FROM PUBLISHER]
