Abstract

A substantial percentage of children develop an anxiety disorder. Epidemiological studies found prevalence rates ranging from 5 to 20%. Taking these high prevalence estimates into account, it is very important to examine the factors that contribute to the etiology of anxiety disorders in children. Behavioral Inhibition (BI) is a laboratory-based temperamental construct. Children who are characterized by a behaviorally inhibited temperament tend to display fear and withdrawal in situations that are novel or unfamiliar. Research has shown that behavioral inhibition is relatively stable over time and that these inhibited children seem to be at risk of developing anxiety disorders. Biederman and colleagues found some evidence for this in their study. The results showed that children with behavioral inhibition had higher rates of anxiety disorders than children without behavioral inhibition when reexamined after 3 years. This research project will elaborate on these findings. On the one hand, a longitudinal study will be conducted to check whether behavioral inhibition contributes to the development of anxiety disorders. And on the other hand, some laboratory-studies will be conducted to reveal the biological correlates of behavioral inhibition, like the startle reflex, cortisol levels and EEG measurements.

Abstract (NL)

In dit proefschrift worden verschillende studies beschreven naar extreme verlegenheid, oftewel gedragsinhibitie, en de ontwikkeling van angststoornissen bij kinderen. In de laatste, meest uitgebreide, studie werden gedurende drie jaar 260 kinderen en hun ouders gevolgd. Elk jaar werd bepaald in welke mate het kind gedragsinhibitie, angstsymptomen of andere psychopathologiesymptomen vertoonden. Bovendien werd gekeken naar andere risicofactoren voor ontwikkeling van angstproblemen, zoals angst bij de ouder, hechting tussen ouder en kind, opvoedingsstijl en ingrijpende levensgebeurtenissen. De studie toont aan dat extreem verlegen kinderen inderdaad een verhoogde kans hebben op het ontwikkelen van een (sociale) angststoornis. Angst bij de ouder, opvoedingsstijl, hechting en ingrijpende levensgebeurtenissen spelen een belangrijke (soms interactieve) rol bij de totstandkoming van angstsymptomen bij deze kinderen.
