# BIOSOCIAL MODELS OF ADOLESCENT BEHAVIOR

> **NIH NIH R37** · UNIV OF NORTH CAROLINA CHAPEL HILL · 1994 · $216,592

## Abstract

This application proposes the extension to panel design of the
theretical model developed in previous phases of the project of
biological and social determinants of female sexual behavior in
adolescence.  The research design replicates insofar as possible
the design of the on-going panel study of boys.  One hundred white
and 100 black 13-year old females will be studied for two years.
The primary emphasis is to examine how changes over time in steroid
hormones, attractiveness, and social controls determine changes in
sexual behavior.  The design is organized to explain race and sex
differences which have been discovered in previous project work.
An important new theoretical element is the specification of
biosocial interactions, in which the strength of the relationships
between social variables and sexual behavior is hypothesized to be
contingent on levels of steroid hormones.
