The present study extends previous research by examining the relations
hip between adolescent sexual intercourse and several important but ye
t to be studied factors including history of physical abuse, neighborh
ood monitoring, and the adolescent's attachment to school, as well as
factors that have previously shown inconsistent findings. The present
investigation also tests whether a cumulative risk factor model provid
es a useful approach to predicting adolescent sexual activity. Finding
s indicate that there are a number of significant risk factors related
to whether or not adolescents are sexually experienced and that the i
mportance of some of these risk factors vary by gender. The data also
provide strong support for the concept of cumulative risk and suggest
that the more risk factors present in adolescents' lives, the greater
the likelihood that they will be sexually experienced.
