Marshall-Berenz EC, Vujanovic AA, Bonn-Miller MO, Bernstein A, Zvolensky MJ. Multimethod study of distress tolerance and PTSD symptom severity in a trauma-exposed community sample. Journal of traumatic stress. 2010 Oct 1; 23(5):623-30.
Despite initial evidence linking distress tolerance to posttraumatic stress disorder (PTSD) symptom severity, there is a need for the investigation of interrelations among multiple measures of distress tolerance and PTSD symptom severity. Therefore, the present study investigated concurrent relations among multiple measures of distress tolerance, as well as the relations between these measures and PTSD symptom severity, within a trauma-exposed community sample. The sample consisted of 81 trauma-exposed adults (63.1% women). Results indicated that Distress Tolerance Scale (Simons and Gaher, 2005) scores, but no other measures of distress tolerance were significantly related to PTSD symptom severity above and beyond the variance accounted for by number of traumas, trait-level neuroticism, and participant sex. Implications and future directions are discussed.
