- impact on families, schools, and communities, and predict delinquency and substance abuse
in adulthood (e.g., Fergusson et al 1994; Frick et al 1993; Loeber 1982; Moffitt et al 1996,
2002; Nagin and Tremblay 1999; Robbins 1966). Therefore, research aimed at identifying
early risk factors and at mechanisms that determine change in symptoms across time is
needed (Côté et al 2002; Deater-Deckard et al 1998; Hinshaw 2002; Lahey et al 2002; Loeber
et al 1995; Nagin and Tremblay 1999).
Although it is clear that disruptive behaviors are influenced by familial, situational,
and societal factors, increasing evidence underscores the importance of genetic and other
biological processes (Brunner et al 1993; Caspi et al 2002; Coccaro et al 1996; Kruesi et al
1992). Alterations in the hypothalamic-pituitary-adrenal (HPA) system and the autonomic
nervous system (ANS), two major physiological stress response systems, have often been
associated with disruptive behavior problems in children and adolescents (e.g. Vanyukov et al
1993; Mc Burnett et al 2000; Pajer et al 2001; Shoal et al 2003; Van de Wiel et al 2004;
Scerbo and Kolko, 1994; Ortiz and Raine 2004; Mezzacappa et al 1997; Allen et al 2000).
The introduction comprises four main components. Firstly, the different constructs of
disruptive behaviors as provided by the DSM-IV (APA 1994) will be described. The two
stress response systems will then be discussed. By explaining the arousal theories in the
following part, the link between disruptive behaviors and the stress response systems will be
clarified. Thirdly, the aims of the thesis will be formulated and the TRAILS-sample will be
described. The introduction concludes with an outline of this thesis.
