Traumatic events have the capability to alter people’s psychological, biological, and social functioning to a significant degree (van der Kolk & McFarlane, 1996). As a result, there has been a growing need to develop increasingly more sophisticated models to understand the complexities of people’s responses to trauma (Luxenberg & Levin, 2004). Undergraduate students (N = 391) completed surveys designed to measure past trauma, trauma-related symptoms, self-regulation, executive functioning, and coping abilities. Participants completed a demographic questionnaire, a modified version of the Early Trauma Inventory Self-Report – Short Form (ETISR-SF; Bremner, Vermetten, & Masure, 2000), the Trauma Symptom Inventory – Alternate Form (TSI-A; Briere, 1995), the Dysexecutive Questionnaire (DEX; Wilson, Alderman, Burgess, Emslie, & Evans, 1996), the Self-Regulation Questionnaire (SRQ; Brown, Miller, & Lawendowski, 1999), and the Coping Resources Inventory for Stress – Short Form (CRIS-SF; Curlette & Matheny, 2008). Structural equation modeling (SEM) was utilized to simultaneously assess the relationships between variables. On average, participants reported experiencing 2.5 non-interpersonal traumatic events and 3.5 interpersonal traumatic events. Results revealed that overall, self-regulation, executive functioning, and tension control were important mediating variables in the relation between experiencing a trauma and resulting symptoms. Implications for clinicians working with individuals who experienced trauma and implications for future research are discussed.
