Adolescents' peer structures and the quality of their friendships were expl
ored as antecedents of romantic relationships. Longitudinal data were gathe
red in a sample of 180 high school students over a 3-year period from grade
9 to grade 11. Consistent with Dunphy (1963), small groups of close friend
s were predictive of other-sex peer networks which were, in turn predictive
of the emergence of future romantic relationships. Indirect effects were f
ound for same-sex groups of close friends and same-sex networks. Consistent
with Furman and Wehner (1994), the qualitative features of relationships w
ith both friends and romantic partners were predictive of the qualitative f
eatures of subsequent romantic experiences. These linkages suggest ways in
which peer relationships may support romantic development at this stage of
the life cycle.
