Cortisol levels in relation to maternal interaction and child internalizing behavior in preterm and full-term children at 18 months corrected age

Cortisol levels were compared in children born preterm at extremely low gestational age (ELGA; 24-28 weeks), very low gestational age (VGLA; 29-32 weeks), and full-term in response to cognitive assessment at 18 months corrected age (CA). Further, we investigated the relationship between maternal interactive behaviors and child internalizing behaviors (rated by the mother) in relation to child cortisol levels. EGLA children had higher "pretest" cortisol levels and a different pattern of cortisol response to cognitive assessment compared to VGLA and full-terms. Higher cortisol levels in ELGA, but not full-term, children were associated with less optimal mother interactive behavior. Moreover, the pattern of cortisol change was related to internalizing behaviors among ELGA, and to a lesser degree VLGA children. In conclusion, our findings suggest altered programming of the hypothalamic-pituitary-adrenal (HPA) axis in preterm children, as well as their greater sensitivity to environmental context such as maternal interactive behavior.

Relations Between Political Violence and Child Adjustment: a four-wave test of the role of emotional insecurity about community

This study further explored the impact of sectarian violence and children's emotional insecurity about community on child maladjustment using a 4-wave longitudinal design. The study included 999 mother-child dyads in Belfast, Northern Ireland (482 boys, 517 girls). Across the 4 waves, child mean age was 12.19 (SD = 1.82), 13.24 (SD = 1.83), 13.61 (SD = 1.99), and 14.66 years (SD = 1.96), respectively. Building on previous studies of the role of emotional insecurity in child adjustment, the current study examines within-person change in emotional insecurity using latent growth curve analyses. The results showed that children's trajectories of emotional insecurity about community were related to risk for developing conduct and emotion problems. These findings controlled for earlier adjustment problems, age, and gender, and took into account the time-varying nature of experience with sectarian violence. Discussion considers the implications for children's emotional insecurity about community for relations between political violence and children's adjustment, including the significance of trajectories of emotional insecurity over time.

Longitudinal relations between sectarian and nonsectarian community violence and child adjustment in Northern Ireland

Although relations between political violence and child adjustment are well documented, longitudinal research is needed to adequately address the many questions remaining about the contexts and developmental trajectories underlying the effects on children in areas of political violence. The study examined the relations between sectarian and nonsectarian community violence and adolescent adjustment problems over 4 consecutive years. Participants included 999 mother-child dyads (482 boys, 517 girls), M ages = 12.18 (SD = 1.82), 13.24 (SD = 1.83), 13.61 (SD = 1.99), and 14.66 (SD = 1.96) years, respectively, living in socially deprived neighborhoods in Belfast, Northern Ireland, a context of historical and ongoing political violence. In examining trajectories of adjustment problems, including youth experience with both sectarian and nonsectarian antisocial behaviors, sectarian antisocial behavior significantly predicted more adjustment problems across the 4 years of the study. Experiencing sectarian antisocial behavior was related to increased adolescent adjustment problems, and this relationship was accentuated in neighborhoods characterized by higher crime rates. The discussion considers the implications for further validating the distinction between sectarian and nonsectarian violence, including consideration of neighborhood crime levels, from the child's perspective in a setting of political violence.
