Trajectories of social outcomes in individuals born very preterm from childhood to adolescence.

Aim: To compare trajectories of social functioning in peer problems and prosocial behavior from 5 to 13 years between individuals born very preterm (VPT) and full-term (FT).

Methods: Participants were from the Victorian Infant Brain Study (VIBeS) longitudinal cohort, consisting of 224 individuals born VPT and 77 born FT recruited at birth. Social functioning was measured using the parent-rated Strengths and Difficulties Questionnaire (SDQ) peer problems and prosocial behavior subscales at 5, 7, and 13 years' corrected age.
