    Author: Morina N, Böhme HF, Morina L, Asmundson GJ.
    Journal: Psychiatry Res; 2011 Apr 30; 186(2-3):306-9. PubMed ID: 20728944.
    Abstract:
    Research on the dimensionality of post-traumatic stress disorder (PTSD) has generally failed to provide support for the three clusters of PTSD suggested in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). However, much research has been restricted to samples in North America and Western European countries. The aim of the current study was to test four alternative factor models among a relatively understudied population-young civilian survivors of war who had experienced war-related events as adolescents-in order to establish whether the factor structure of PTSD is consistent among various traumatized populations and age groups. Using the Posttraumatic Stress Diagnostic Scale, the results indicated that the four-factor model including intrusion, avoidance, hyperarousal, and numbing factors provided a better fit than the three-factor model suggested by the DSM-IV. The current study offers additional support from another population for a four-factor model of PTSD that implies a separation of avoidance and numbing items. Case conceptualization and treatment implications are discussed.
