BLANCO, Amalio; DIAZ, Darío; GABORIT, Mauricio  and  AMARIS, María del Carmen. World Schema and Self Schema: The Posttraumatic Cognitions Inventory (PTCI) in Hispanic Population. rev.latinoam.psicol. [online]. 2010, vol.42, n.1, pp.97-102. ISSN 0120-0534.

The main purpose of the present article was to analyze in Hispanic population the psychometric properties of Posttraumatic Cognitions Inventory (PTCI), a measure of trauma-related thoughts and beliefs developed by Edna B. Foa. The inventory was administered to 132 participants of general population of Spain, 363 participants of El Salvador, and 47 direct victims of 11-M terrorist attacks in Spain. The PTCI factorial structure was analyzed using Parallel Analyses of Horn and exploratory and confirmatory factor analyses. Results showed three factors that explained 51% of variance: Negative Cognitions About Self (35%), Negative Cognitions About the World (10%), and Self-Blame (6%). CFA confirmed the three factors structure without a second order factor (CFI =0,93) and with this general factor (CFI = 0,93). The three dimensions showed good internal consistency with general Cronbach α levels higher than 0,70. PTCI correlated with trauma severity (r = 0,61) and with other measures of trauma-related cognitions. Finally, the PTCI discriminate with precision between traumatized and not traumatized individuals.
