Previous research has not yielded consistent identity and intimacy associations for female and male emerging adults. Intimacy varies with time spent in a relationship, and relationship duration may explain variations in the identity process association with intimacy. Data from 278 female and 156 male emerging adults revealed relationship duration moderated the identity commitment and exploration associations with intimacy. Findings indicated longer relationship duration was associated with lower intimacy levels for high identity commitment/high exploration females, and longer relationship duration was associated with higher intimacy levels for high commitment/low exploration females. Findings also indicated longer relationship duration was associated with higher intimacy levels for high commitment/high exploration males, and longer relationship duration was associated with lower intimacy levels for low commitment/high exploration males. Findings are discussed with regards to the empirical importance of considering relationship characteristics when examining emerging adult identity process associations with friendship intimacy.
