Child temperament and sibling temperament similarity have been shown to influence sibling relationship quality. This study examined extraversion in relation to sibling warmth and conflict in twins longitudinally at 7 and 14 years. Higher extraversion and twin concordance at age 7 significantly related to higher sibling conflict at both ages.
