Child abuse history in teen mothers and parent-child risk processes for offspring externalizing problems

This study examined whether child abuse history in teen mothers impacts offspring externalizing problems indirectly, through its influence on attachment and maternal hostility. In a longitudinal sample of 112 teen mother-child dyads, mothers reported on their own abuse experiences, attachment and maternal hostility were assessed via direct observations, and externalizing problems were measured using maternal reports. Compared with mothers with no abuse history, mothers with a history of sexual and physical abuse were more likely to have an insecurely attached infant, which predicted higher externalizing problems in preschool, which in turn predicted subsequent increases in externalizing problems in Grade 3. Furthermore, relative to the no abuse history group, mothers with a history of sexual and physical abuse showed more hostility toward their child at preschool, which in turn predicted elevated externalizing problems in Grade 3. Mothers' history of either sexual or physical abuse alone did not have significant indirect effects on externalizing problems. Fostering secure attachment and reducing risk for maternal hostility might be important intervention goals for prevention programs involving at-risk mothers with abuse histories.
