Earlier
initiation of romantic
relationships and more frequent alcohol use were
predicted by greater sociability and less impulsivity in childhood, higher quality friendships and greater peer acceptance in early adolescence, and a more mature appearance and physical attractiveness (among females) at age 13.
For example, partners who believe that they did more of the work of
relationship initiation may come to feel especially committed to their
relationship, as would be
predicted by a cognitive dissonance framework on justifying effort (e.g., Aronson & Mills, 1959).
