Predicting externalizing behavior in toddlerhood from early individual differences in empathy

Background From middle childhood onward, there is often a negative link between empathy and externalizing behavior problems. Patterns at younger ages are still unclear, with mixed findings of no association, negative associations, and positive associations. This study examines links between empathy and externalizing problems, beginning in infancy. Methods A community sample of infants (N = 165) was assessed for empathy at 3, 6, 12, 18, and 36 months, using behavioral observations. Externalizing problems were reported at 18 months (by mothers) and 36 months (by mothers and daycare teachers). Results Boys showed more externalizing problems than girls. For boys, negative associations between empathy and externalizing appeared, particularly with teacher reports. For girls, there were positive associations between empathy and externalizing, which weakened with age. For both genders, empathy at ages 3, 6, and 18 months appeared to protect against increases in externalizing from 18 to 36 months. Conclusions The role of empathy in the development of early externalizing depends on both gender and age; toddler boys' externalizing may more typically stem from low empathy, whereas girls' early externalizing appears to be underlain by heightened sensitivity and unregulated or assertive approach attempts.
