Aim: determine how testosterone levels, both alone and interacting
with age, were associated with criminal behavior and institutional
behavior amongst female prisoners.
Participant: 87 female prisoners in a
maximum security state prison.
Criminal behavior was scored from court records and
institutional behavior was scored from prison records
and interviews with staff members. Testosterone levels
were scored from saliva samples.
Correlations were found between age,
testosterone, criminal behavior and
institutional behavior.
Analysis suggested that the higher the age the
lower the testosterone levels, which in turn leads
to less violent crime and less aggressive
dominance in prison.
Testosterone is related to criminal violence and
aggressive dominance in prison among women, as
has been reported among men.
Changes in behavior with age are in part
explained by a decline in testosterone levels.
