Abstract
Individuals with a history of foster care (FC) are at elevated risk for emotion regulation-related mental illness. The purpose of the current study was to characterize regulatory function in a group of adults with a history of FC (N = 26) relative to those without a history of FC (N = 27) and how regulatory function moderates adverse caregiving-related outcomes (daily cortisol production and trait anxiety). Self-report items (anxiety, emotion regulation strategies, inhibitory control, caregiving history) were collected along with more objective measures (computerized task and salivary cortisol). Inhibitory control was assessed via self-report and a computerized task (emotional face go/nogo). Results showed that for adults with a history of FC, higher levels of inhibitory control were associated with higher accuracy on the emotional face go/nogo task and greater reported use of the emotion regulation strategy cognitive reappraisal. Greater use of cognitive reappraisal in turn was associated with healthier stress-related outcomes (decreased trait anxiety and steeper sloped cortisol production throughout the day). Dose-response associations were observed between self-reported regulatory skills and FC experiences (i.e., number of placements and age when exited foster care). These findings suggest that adverse caregiving can have long-term influences on mental health that extend into adulthood; however, individual differences in regulatory skills moderate these outcomes and may be an important target for intervention following caregiving adversity.
