Abstract
Stress, Cortisol, and Externalizing Behavior in Adolescent Males: An Examination in the
Context of Multisystemic Therapy
By Julia C. Schechter
Aggression and delinquency are associated with an array of emotional, behavioral, and
health problems (Loeber, Burke, Lahey, Winters, & Zera, 2000). Additionally, a
multitude of variables are thought to lead to the development of externalizing disorders in
adolescent males. The purpose of the current study was to investigate the relationship
among stress, cortisol, and externalizing behaviors in males, specifically in a treatment
context. In an effort to examine potential differential effects of stressor types, measures
of stress were delineated into lifetime, current episodic, and daily hassles sub-categories.
This study examined data from a sample of 120 adolescent males (mean age = 15 years)
referred to Multisystemic Therapy (MST) for externalizing problems. Partial correlations
were used to examine concurrent relationships among self-reported stress, morning
cortisol, and externalizing problems (parent reports of aggression and delinquency) at
time of referral. Analyses did not yield significant relationships between stress or cortisol
and externalizing behavior prior to treatment. Regression analyses were used to measure
whether cortisol or stress predicted treatment outcome for youths with externalizing
behavior problems. Results indicated that compared to youth who had experienced fewer
hassles, youth that had experienced more daily hassles had higher levels of externalizing
behavior after treatment. This relationship was moderated by cortisol levels at
awakening, such that youth with more daily hassles and high levels of cortisol had the
worst outcome at post treatment. This interaction remained significant after controlling
for post treatment internalizing disorders. Implications and future directions for treatment
are discussed.
