Intergenerational aspects of the development of aggression: a preliminary report.

Across studies in a variety of environmental settings, secure attachment relationships early in life are associated with a lower rate of abnormally aggressive patterns of behavior later in childhood. The quality of an attachment relationship can be predicted by a recently developed measure of parents' mental representations of their own early childhood relationships, the Adult Attachment Interview (AAI). AAI classifications of single parents of abnormally aggressive preschoolers (n = 10) from two low income day care centers were compared with those of single parents of age-, race-, sex-, and center-matched controls (n = 10). All abnormally aggressive children had parents classified as insecure on the AAI; parents of all but one of the nonaggressive controls were classified as secure (p < .001). The AAI may be a useful intergenerational predictor of antisocial and resilient outcomes among children for whom a single caregiver is the only resource for longstanding attachment relationships. Efforts to enhance the constellation of children's early attachment relationships may serve to prevent antisocial outcome.

Testosterone and aggression in children.

OBJECTIVE: A link between serum testosterone and aggressive behavior, which has been demonstrated in numerous animal studies and suggested in several studies of adult men, has never been investigated in children before the time of puberty. METHOD: We measured serum testosterone, sex hormone binding globulin (SHBG), dehydroepiandrosterone (DHEA), and dehydroepiandrosterone sulfate (DHEAS) in 18 highly aggressive prepubertal boys, ages 4 to 10, hospitalized for violent or unmanageable behavior at a state children's psychiatric facility in New York City (the Bronx). We compared them with a group of age and race matched controls from the same demographic area, screened negative for aggressive behavior problems. All the aggressive subjects met DSM-III-R criteria for conduct disorder and scored higher than the 98th percentile on the aggression subscale of the Child Behavior Checklist (mean T = 80 for the group). RESULTS: There were no significant differences between aggressive and nonaggressive children for T, SHBG, DHEA, DHEAS, or ratios of combinations of these variables. CONCLUSIONS: These findings raise questions about inferences from adult studies that testosterone may play a causal role in the development of human aggression. Testosterone does not appear to be a useful biological marker for aggressivity in early childhood.
