Neuroendocrine regulation and physical and relational aggression: the moderating roles of child maltreatment and gender

The purpose of the present investigation was to examine the association between circadian rhythms of cortisol and physical and relational aggression. Morning arrival, prelunch, and afternoon predeparture salivary cortisol were assessed among 418 maltreated and nonmaltreated children (52% maltreated; 49% female) attending a summer day camp. Counselors and peers rated participants' involvement in physically and relationally aggressive behaviors. Results indicated that physical aggression was associated with heightened cortisol following morning arrival and relatively steep declines in cortisol over the day, whereas relational aggression was associated with low cortisol following morning arrival and blunted diurnal change in cortisol. Moreover, maltreatment was a significant moderator of this relationship such that aggression was related to greater cortisol dysregulation among nonmaltreated than among maltreated children. The findings suggest that physiological correlates of aggression may differ for physical and relational forms of aggression and among maltreated versus nonmaltreated populations.     

Substance use and symptomatology among adolescent children of alcoholics.

This study assessed the magnitude and specificity of parental alcoholism as a risk factor for internalizing symptomatology, externalizing symptomatology, and alcohol and drug use in adolescence. We evaluated parents' and children's reports of symptomatology and children's reports of alcohol and drug use in a community sample of 454 adolescents. The results showed that parental alcoholism was a moderate to strong risk factor, with stronger risk associated with recent (rather than remitted) parental alcoholism. Multivariate analyses showed that the specificity of risk varied with the outcome measure. In predicting externalizing symptomatology, the risk associated with parental alcoholism was mediated by co-occurring parental psychopathology and environmental stress. However, in predicting alcohol use, the father's alcoholism was a specific risk factor above and beyond the more generalized effects of stress and family disruption.     

A Review of: “Fairburn,C. G. (2008). Cognitive Behavior Therapy and Eating Disorders.”

Successful reports of behavioral treatment of encopresis describe interventions as unpleasant as the disorder: hospitalization, laxatives, prompted toileting, aversive consequences. The focus on soiling rather than on the constant constipation that precedes encopresis, on the reduction of soiling rather than on the acquisition of effective toilet use. Five normal chronically constipated children (four of whom were encopretic) were treated at home with combinations of: preparatory instructions, rewards for clean pants, reward for appropriate toileting (bowel movement in toilet). Once soiling was eliminated and appropriate bowel movements occured regularly, all families were taught to fade treatment contingencies. To determine the contribution of the toileting reward to treatment effectiveness, this reward was added to the other two treatment components in a multiple baseline across four cases; it provided a significant ingredient in short-term success. A fifth child achieved short-term success with only the instructions and the clean pants reward. Long-term results (11-20 months) revealed that the fifth child, who never received the toileting reward, was the only one who relapsed.     

Narrative representations of moral-affiliative and conflictual themes and behavioral problems in maltreated preschoolers

Examined whether maltreated preschoolers are more likely than nonmaltreated preschoolers to have fewer moral-affiliative and more conflictual narrative representations and whether these representations mediate child behavior problems. A structured narrative story-telling task was administered to assess representations, and independent ratings of behavior problems were obtained from teachers. The narratives of maltreated children contained more conflictual and fewer moral-affiliative themes. Maltreated children also exhibited more internalizing and externalizing behavior problems. A partial mediation effect of conflictual representations on the relation between child maltreatment and externalizing behavior problems was found. The results demonstrate the relation between child maltreatment and children's organization of their life experiences and their behavioral symptomatology.     

Early-occurring Maternal Depression and Maternal Negativity in Predicting Young Children’s Emotion Regulation and Socioemotional Difficulties

This longitudinal investigation examined the effects of maternal depression and concomitant negative parenting behaviors on children’s emotion regulation patterns and socioemotional functioning. One hundred fifty-one mothers and their children were assessed when children were approximately 1 1/2-, 3-, 4-, and 5-years of age. Ninety-three of the children had mothers with a history of Major Depressive Disorder (MDD) that had occurred within the first 21 months of the child’s birth, and 58 of the children had mothers without any history of MDD. Early-occurring Initial maternal depression predicted children’s dysregulated emotion patterns at age 4 and decreased perceived competence ratings at age 5. Initial maternal depression also indirectly predicted decreased child social acceptance ratings at age 5 through its association with dysregulated emotion patterns. Furthermore, the relation between maternal depression and children’s decreased social acceptance was more pronounced in those offspring with a history of high versus low maternal negativity exposure. Findings increase understanding of the processes by which maternal depression confers risk on children’s socioemotional adjustment.
