Variable- and person-oriented approaches were used to examine the affiliative and romantic experiences of adolescents in heterosexual romantic relationships and its associations with relationship conflict and jealousy on a sample of 194 romantic partner dyads. Variable-oriented findings indicated that affiliative experiences were associated with fewer and more constructively resolved conflicts, whereas romantic experiences were associated with more jealousy. Person-oriented analyses identified six distinct types of romantic relationships: four characterized by congruent perceptions and two characterized by incongruent perceptions. Adolescents in the consummate group (both partners reporting high levels of affiliation and romance) had the fewest but most constructively resolved conflicts. The discussion focuses on the developmental significance of dyadic similarity and the early developmental roots of diversity in romantic relationships.
