K. Lyonsruth, ATTACHMENT RELATIONSHIPS AMONG CHILDREN WITH AGGRESSIVE-BEHAVIOR PROBLEMS - THE ROLE OF DISORGANIZED EARLY ATTACHMENT PATTERNS, Journal of consulting and clinical psychology, 64(1), 1996, pp. 64-73
This article reviews recent attachment-related studies of early aggres
sion. That aggressive behavior toward peers is related to disorganized
or controlling patterns of attachment behavior toward parents but not
to avoidant or ambivalent patterns. Longitudinal attachment studies i
ndicate that risk factors identified in cross-sectional studies of agg
ressive school-age children, such as family adversity, parental hostil
ity, parental depression, and child cognitive deficits, are already ev
ident in infancy and predictive of later aggression, before the onset
of coercive child behavior. In infancy, these risk factors are associa
ted with disorganized attachment behaviors toward the caregiver charac
terized by signs of fear or dysphoria, irresolvable conflict between o
pposing behavioral tendencies, and elevated cortisol levels after sepa
ration. Disorganized attachment behaviors, in turn, predict aggression
in school-age children with other family factors controlled.
