The present investigation evaluated the main and interactive effects of distress tolerance and negative affect intensity in relation to posttraumatic stress disorder (PTSD) symptom severity and symptom cluster severity. Participants were 190 trauma-exposed adults (52.6 % women; M age = 25.3 years, SD = 11.4) recruited from the community. Distress tolerance (i.e., perceived ability to withstand distressing emotional states) demonstrated significant incremental associations with global PTSD symptom severity as well as Re-Experiencing, Emotional Numbing, and Hyperarousal symptom cluster severity. Negative affect intensity (i.e., perceived intensity of negative emotional responses) demonstrated significant incremental associations with each of the PTSD symptom outcomes. Moreover, the incremental interactive effect of distress tolerance and negative affect intensity was significantly associated with PTSD symptom severity as well as PTSD - Emotional Numbing symptom cluster severity. These incremental effects were evident after accounting for the variance explained by anxiety sensitivity (i.e., fear of anxiety-related sensations). Post hoc probing analyses supported the moderating role of negative affect intensity in the association between distress tolerance and PTSD symptom severity, such that low levels of distress tolerance, in the context of elevated levels of negative affect intensity, were associated with the greatest levels of PTSD symptoms.
