Abstract

ABSTRACT: Symptoms of posttraumatic stress disorder (PTSD) are common reactions to trauma. One factor that influences the manifestation of PTSD symptoms is the type of trauma experienced. Traumas perpetrated by someone on whom the trauma survivor trusts and relies on for support (i.e., betrayal traumas) are especially predictive of PTSD symptoms. However, the degree to which this is true differs somewhat across men and women. Another factor that influences PTSD symptoms is personality, which is most often operationalized in terms of discrete personality traits. Among these traits, Neuroticism (the tendency to experience negative affect) is linked to a wide range of psychological dysfunction in general and to PTSD symptoms in particular. However, there is little research on how trauma type and personality differentially influence PTSD symptoms. To address this gap, in this study we examined the incremental effects of traumas with varying degrees of betrayal and personality traits on PTSD symptoms in a sample of college students ( N = 276) using a Bayesian approach to multiple regression. Results suggest that Neuroticism and trauma at all levels of betrayal were associated with higher levels of PTSD symptoms, although this differed across sex. These results are consistent with previous research that identifies Neuroticism as a risk factor for a wide range of mental health problems and clarifies earlier findings on betrayal trauma.
