Problem Behavior and Heart Rate Reactivity in Adopted Adolescents: Longitudinal and Concurrent Relations

The present longitudinal study examined resting heart rate and heart rate variability and reactivity to a stressful gambling task in adopted adolescents with aggressive, delinquent, or internalizing behavior problems and adopted adolescents without behavior problems (total N=151). Early‐onset delinquent adolescents showed heart rate hyporeactivity to the stress‐eliciting gambling task compared to late‐onset delinquent adolescents and adolescents without behavior problems. Heart rate, heart rate variability, and reactivity to stress were not related to environmental factors such as early‐childhood parental sensitivity, parental socioeconomic status, or adoptee's health status at arrival. We conclude that the distinction between delinquency and aggression and between childhood‐onset and adolescence‐onset delinquency is important for the study of stress reactivity in adolescents.     

Maternal Sensitivity Moderates the Relation between Negative Discipline and Aggression in Early Childhood

Three models regarding the relation between maternal (in)sensitivity, negative discipline, and child aggression were examined in a sample of 117 mother–child pairs with high scores on child externalizing behavior: (1) Sensitivity and discipline are uniquely related to child aggression (the additive model); (2) the relation between discipline and aggression is moderated by maternal sensitivity (the moderating model); (3) the relation between sensitivity and aggression is mediated by maternal discipline (the mediating model). Parenting and child aggression were observed when the children were on average 26.71 months old (range of 13.58 to 41.91 months) and again one year later. Results supported the moderating model. More negative discipline was related to more child aggression one year later, but only when mothers were insensitive. This finding supports the idea that the affective context is important for the impact of negative discipline on child development.     

DIRTY DIAPERS AND THE NEW ORGANIC INTELLECTUAL

This article examines the conjuncture in the last decade of the political, economic, demographic and cultural forces in the USA that have facilitated the emergence of a complex identity category, the ‘single mom’ – a category that has come to stand for the failure of the welfare state and the purported possibilities of neo-liberal self-sufficiency as well as for the rearticulation of those conditions. The ‘rationalities of government’ that make freedom an increasingly difficult state for poor women to achieve are connected to the production of a set of ‘practices of the self’, in the form of cultural texts ranging from self-help literature to television and film that represent and advise single mothers on how to demonstrate their self-sufficiency and self-governance. It is argued that analysis of single mothers is a critical component of understanding current social conditions as they are played out in the USA in the realms of domesticity, family and mothering, realms often given short shrift in comparison to cultural studies' work on public cultures and spaces.     

Delinquent and aggressive behaviors in early-adopted adolescents: Longitudinal predictions from child temperament and maternal sensitivity

Background

160 early-adopted children were followed from infancy to adolescence. Central question was whether early and concurrent parenting and child temperament predicted adolescent delinquent and aggressive behaviors.

Methods

Structural equation modeling was used to test the relations between early and concurrent observed maternal sensitivity, mother reported effortful control and teacher reported delinquent and aggressive behaviors.

Results

This longitudinal adoption study showed that lower effortful control, concurrent as well as 7 years earlier, predicted higher levels of delinquency in adolescence and aggression in middle childhood and in adolescence. Lower levels of effortful control in infancy predicted higher levels of maternal sensitivity in adolescence which in its turn predicted less adolescent delinquent behavior.

Conclusions

The findings suggest that effortful control is an important predictor of both aggressive and delinquent behaviors. Maternal sensitivity also plays a role in the development of delinquent behavior, buffering a lack of effortful control, but is not related to aggression at age 14. It is important to note that these relations were found in a sample of parents and their genetically unrelated adopted children.
