Interpersonal trauma exposure and startle reactivity to uncertain threat in individuals with alcohol use disorder

摘要

Background: Exposure to interpersonal trauma is highly prevalent within individuals with alcohol use disorder (AUD); however, the mechanisms underlying the pathway between trauma exposure and AUD are unclear. Preliminary evidence suggests that heightened reactivity to threats that are uncertain (U-threat) may characterize individuals with AUD and interpersonal trauma exposure and contribute to alcohol abuse within this subgroup of individuals; however, this hypothesis has yet to be tested.
