The present study tested the hypothesis that among women with eating disorders (EDs), who are known to have an elevated risk for death by suicide, non-suicidal self-injury (NSSI) and ED behaviors would mediate the relationship between poor interoception and the two components of the acquired capability for suicide (ACS). Adult women with EDs (N = 98) provided self-report data regarding interoceptive deficits (ID), NSSI, ED behaviors, and the two components of ACS: fearlessness about death and pain tolerance. ID significantly predicted NSSI but not ED behaviors. ID was a strong predictor of fearlessness about death, while NSSI was a strong predictor of pain tolerance. The indirect effect of ID on pain tolerance, through NSSI was significant. No ED behaviors significantly predicted either component of ACS. The present results highlight the associations between interoceptive deficits, NSSI and the acquired capability for suicide, among women with EDs.
