The posttraumatic cognitions inventory (PTCI) has emerged as a well-supported measure of trauma-related cognitions and has been associated with overall posttraumatic stress disorder (PTSD) severity. The present study sought to contribute to the literature regarding the utility of this measure and importance of considering the role of trauma-related cognitions in relation to an emerging four-factor model of PTSD symptomatology. To address discrepancies in the previous literature, we first replicated prior research by investigating the relationship between the PTCI cognitions (self, world/other, and self-blame) and overall PTSD symptoms. Next, we used structural equation modeling to examine a model of the relationships between posttraumatic cognitions and a well-supported four-factor model of PTSD (including separate avoidance and numbing clusters). We assessed PTSD symptomatology using both clinician-administered and self-report instruments in a treatment-seeking sample of sexual assault survivors. Results largely supported the theorized model of relationships between posttraumatic cognitions and PTSD symptom clusters. Discrepancies were observed between the two PTSD measures, which may help to clarify previous conflicting reports. Clinical and theoretical implications are considered.
