Considerable evidence indicates a prominent role for trauma-related cognitions in the development and maintenance of posttraumatic stress disorder (PTSD) symptoms. The present study utilized regression analysis to examine the unique relationships between various trauma-related cognitions and PTSD symptoms after controlling for gender and measures of general affective distress in a large sample of trauma-exposed college students. In terms of trauma-related cognitions, only negative cognitions about the self were related to PTSD symptom severity. Gender and anxiety symptoms were also related to PTSD symptom severity. Theoretical implications of the results are discussed.
KeywordsPosttraumatic Stress Disorder; PTSD; Cognitions; Anxiety; Trauma Exposure to traumatic events is quite common, with estimated lifetime rates ranging from 26% to 92.2% in men and from 17.7% to 87.1% in women (Breslau, Davis, Andreski, & Peterson, 1991;Breslau et al., 1999;Creamer, Burgess, & McFarlane, 2001;Kessler et al., 1995;Norris, 1992;Perkonigg, Kessler, Storz, & Wittchen, 2000;Resnick, Kilpatrick, Dansky, Saunders, & Best, 1993;Stein et al., 1997). Although many people experience trauma, only a subset of these individuals subsequently develops posttraumatic stress disorder (PTSD). Lifetime prevalence rates for PTSD range from 1% to 12.3% (Breslau, Davis, Andreski, & Peterson, 1991;Davidson, Hughes, Blazer, & George, 1991;Kessler et al., 1995;Resnick et al., 1993) and current rates of PTSD range from .4% to .9% (Andrews et al., 2001;Perkonigg et al., 2000). PTSD tends to have a chronic course, with as many as 40% continuing to exhibit significant symptoms of the disorder 10 years after its onset (Kessler et al., 1995).Several theories underscore the role that cognitive variables play in the development and maintenance of PTSD (Ehlers & Clark, 2000; Epstien, 1991;Foa & Cahill, 2001;Foa & Jaycox, 1999;Foa & Riggs, 1993;Foa & Rothbaum, 1998;Horowitz, 1986;Janoff-Bulman, 1992;McCann & Pearlman, 1990;Resick & Schnicke, 1992). Utilizing the framework of emotional processing theory (Foa & Kozak, 1986), Foa and colleagues have emphasized the role of cognitions about the self and the world in natural recovery from trauma, the development of Correspondence concerning this article should be addressed to Jason S.
