Tolerating Distress After Trauma: Differential Associations Between Distress Tolerance and Posttraumatic Stress Symptoms

Distress tolerance has been implicated in disorders of emotional regulation, such as eating disorders and borderline personality disorder; however, much less attention has been given to distress tolerance in the context of posttraumatic stress (PTS). Several conceptual linkages between distress tolerance and PTS exist. Low distress tolerance may increase negative appraisals, reducing an individual’s propensity to deal with distressing mental symptoms immediately after a trauma. Relatedly, a perceived inability to cope with the distress brought on by trauma-related memories and cues may engender maladaptive coping strategies. The few published studies examining the relationship between distress tolerance and PTS have demonstrated that lower distress tolerance was associated with increased PTS symptomatology, including increased avoidance, hyperarousal, and re-experiencing. The current study sought to replicate and extend the emerging empirical base by examining the relationship between distress tolerance and the four distinct PTS symptom clusters, while controlling for time since the index trauma and depressive symptoms. Results indicated that distress tolerance accounted for significant unique variance in re-experiencing and avoidance but not negative emotionality and hyperarousal symptoms. There was also a strong positive association between the number of traumas endorsed by participants, depression, and PTS symptoms. Findings suggest that distress tolerance is associated with PTS, lending further support to the putative relationship between PTS and distress tolerance. Accordingly, developing treatment protocols designed to increase distress tolerance in individuals affected by PTS may reduce symptom severity and increase coping abilities.     

Clarifying the relationship between AS dimensions and PTSD symptom clusters: are negative and positive affectivity theoretically relevant constructs?

The association between anxiety sensitivity (AS) and posttraumatic stress disorder (PTSD) has been established in contemporary literature; however, research is divided over the nature of specific relationships between AS dimensions and PTSD symptoms clusters. Further, a paucity of research has examined the AS and PTSD relationship while accounting for theoretically relevant variables, such as negative (NA) and positive affect (PA). The purpose of the current study was twofold: first, to clarify divergent findings regarding the contribution of AS dimensions to PTSD symptom clusters, and, second, to further assess the relevance of NA and PA within the AS/PTSD relationship. Hierarchal regression analyses showed that, beyond shared variance attributable to NA and PA, AS somatic concerns were significantly associated with three of four PTSD symptom (i.e., reexperiencing, numbing, hyperarousal), AS cognitive concerns were only associated with hyperarousal, and AS socially observable symptoms were not significantly associated with any PTSD symptom clusters. These findings suggest that AS somatic concerns are the most robust predictor of variance within the AS/PTSD relationship and further clarify the theoretical importance of NA and PA within this relationship. Comprehensive results, implication, and directions for future research are discussed.
