Self-perceptions of pubertal timing and patterns of peer group activities and dating behavior among heterosexual adolescent girls

This study identified patterns of past and concurrent peer group and dating behavior in a sample of adolescent girls (N = 511; aged 17–19 years; 49% White). Peer group activities and dating behaviors were classified as occurring in either early (ages 10–13 years), middle (ages 14–16 years), or late (ages 17–19 years) adolescence according to the age at which each participant indicated the activity/behavior was first experienced. Latent class analysis identified four latent classes: Early Interactions/Early Daters (15%), Early Interactions/Late Daters (17%), Early Interactions/Middle Daters (33%) and Middle Interactions/Middle Daters (35%). Class membership was associated with girl's perceived pubertal timing. Compared to Early Interactions/Early Daters, girls in the Early Interactions/Late Daters class reported higher levels of pubertal timing, indicating greater perception that their pubertal development was late relative to peers. Late perceived pubertal timing is potentially relevant for dating but not necessarily other mixed- and cross-sex peer interactions.
