Objectives. Impulsivity is a common reaction following interpersonal trauma (IPT) experiences, such as physical and sexual assault. Research suggests emotion dysregulation (ED) explains the link between IPT and impulsivity. To advance this research, we assessed the indirect effects of ED on associations between physical/sexual assault endorsement and the five impulsivity facets (negative urgency, positive urgency, lack of premeditation, lack of perseverance, sensation seeking). Methods. A sample of 176 participants seeking treatment at a community mental health center [M age = 34.79; women = 52.8%] completed the scales on traumatic experiences, ED, and the five impulsivity facets. Five simple mediation models were conducted to examine the hypothesized indirect effects on each impulsivity facet. Results. Results revealed significant indirect effects of ED in associations between IPT endorsement and negative urgency (B=2.17, SE=0.58, 95% CI [1.09, 3.35]), positive urgency ( B=1.87, SE=0.59, 95% CI [0.84, 3.16]), lack of premeditation ( B=1.92, SE=0.58, 95% CI [0.89, 3.18]), lack of perseverance ( B=1.67, SE=0.49, 95% CI [0.79, 2.73]), and sensation seeking ( B=0.83, SE=0.36, 95% CI [0.20, 1.62]). Conclusion. ED explained the relationship between IPT endorsement and each of the five facets of impulsivity. IPT survivors may experience more ED, which may increase impulsivity. Findings help identify underlying factors that relate to survivors’ level of impulsivity following IPT experiences, as well as suggest trauma treatments targeting ED may be effective in reducing post-trauma impulsivity for these individuals.
