[Abstract]
Individuals with early life stress (ELS) are at an elevated risk for
long-term internalizing problems such as anxiety. This trajectory may be
explained in part by psychophysiological changes (e.g., increased amygdala
volume and dysregulated stress hormone responses) which impair emotion
regulation and lead to aberrant threat responses. Individuals with more ELS
may show a delayed recovery from anxiety after acute stress exposure. Using
a pre-test, post-test, follow-up design, UCLA undergraduates (N=91) were
assessed for state anxiety before and after undergoing social stress
induction through the Trier Social Stress Test or playing video games
(control condition) and at 30-minutes follow-up. Participants also
responded to validated self-report measures of ELS, trait anxiety,
socioeconomic status, and depression. Multivariate generalized linear
modeling revealed a significant interaction between acute stress and
childhood emotional abuse at 30-minutes follow-up but not at post-test over
and above the effects of trait anxiety, socioeconomic status, and
depression. Results indicate that ELS may slow the recovery from stress
without changing the magnitude of the stress response.
