Psychometric properties of the posttraumatic cognitions inventory (PTCI): A replication with motor vehicle accident survivors
Abstract
This study examined the factor structure, internal consistency, concurrent validity, discriminant validity, and discriminative validity of the Posttraumatic Cognitions Inventory (PTCI; E. B. Foa, A. Ehlers, D. M. Clark, D. F. Tolin, & S. M. Orsillo, 1999) in a sample of 112 individuals who had experienced a serious motor vehicle accident. Results generally supported the 3-factor structure of the PTCI: (a) Negative Cognitions About Self, (b) Negative Cognitions About the World, and (c) Self-Blame. Subscales reflecting negative thoughts of the self and world showed adequate internal consistency, as well as good concurrent, discriminant, and discriminative validity. However, difficulties with the subscale representing self-blame emerged, specifically poor concurrent and discriminant validity. Potential reasons for this finding are discussed. The PTCI seems to be a promising measure of negative and dysfunctional posttrauma cognitions, which deserves continuing attention.
