Antisocial behaviour and externalizing problems: Emond A

Emond, A., Ormel, J., Veenstra, R., & Oldehinkel, A. J. (2007). Preschool behavioral and social-cognitive problems as predictors of (pre)adolescent disruptive behavior. Child Psychiatry & Human Development, 38, 221-236.

This article describes preschool social understanding and difficult behavior (hot temper, disobedience, bossiness and bullying) as predictors of Oppositional Defiant Disorder (ODD) and Aggressive Conduct Disorder (ACD) in a Dutch population sample of (pre)adolescents (N = 1943), measured at age 10-12 and at age 13-15. ODD and ACD were assessed by the Child Behavior Checklist and the Youth Self-Report, preschool behavior was evaluated by the parental questionnaire ‘How was your child as a preschooler? (age 4-5)’. Adjusted for each other, all difficult preschool behaviors except bullying were associated with adolescent ODD, while only bullying significantly predicted adolescent ACD. Furthermore, the results suggest a qualitative difference between ODD and ACD in terms of the social component of the disorders: poor preschool social understanding was associated with the development of ACD but not of ODD; and poor social understanding interacted with difficult preschool behaviors to predict later ACD but not ODD. No major differences were found between boys and girls, nor did we find strong evidence for differences between preadolescent (age 10-12) and early adolescent (age 13-15) outcomes. The finding that poor social understanding was implicated in the developed of ACD but not in the development of ODD may help to demarcate the individuality of each disorder and offer leads for (differential) treatment strategies.

Antisocial behaviour and externalizing problems: Sondeijker FEPL

Sondeijker, F. E. P. L., Ferdinand, R. F., Oldehinkel, A. J., Veenstra, R., Tiemeier, H., Ormel, J. et al. (2007). Disruptive behaviors and HPA-axis activity in young adolescent boys and girls from the general population. Journal of Psychiatric Research, 41, 570-578.

It is important to investigate associations between biological factors and disruptive behaviors in children and adolescents. Antisocial, aggressive, and criminal behaviors in adults often begin early in life. Disruptive behaviors are often thought to be associated with low activity of the hypothalamic-pituitary-adrenal (HPA) axis. Cortisol, the end-product of this axis, can be measured to investigate HPA-axis activity. Previous studies on this topic concerned clinical or high risk samples. The aim of the present study was to investigate to which extent HPA-axis functioning plays a role in disruptive behaviors in pre-adolescents from the general population. One thousand seven hundred and sixty eight 10- to 12-year-olds from the Dutch general population were investigated. Disruptive behaviors were assessed with the Child Behavior Checklist, the Youth Self-Report, and the Antisocial Behavior Questionnaire. Baseline morning and evening salivary cortisol levels were assessed. Unexpectedly, small associations were found between disruptive behaviors, including attention problems, and higher cortisol levels. However, all effect sizes of significant effects were very small. Our study indicated that HPA-axis functioning may be more relevant in clinical or high risk samples than at the general population level. The association between HPA-axis functioning and attention problems, that has gotten less attention than that with aggressive or delinquent behaviors, requires further research. Furthermore, because effect sizes were relatively small, it can be concluded that, in pre-adolescence, the measures of baseline HPA-axis functioning that were used for the present study can not be used as biological markers for disruptive behaviors.
