The nature of trauma memory representations and its relationship with posttraumatic psychological symptoms of torture survivors

Abstract

This study explored the nature of trauma memory representations and examined its relationship with posttraumatic psychological symptoms with the participation of 213 torture survivors. Participants completed self-report scales of posttraumatic stress disorder(PTSD) and depressive symptoms, and trauma memory representations were assessed using the self-report Trauma Memory Quality Questionnaire(TMQQ). The TMQQ appeared to assess the sensation-based memory representation, and it was divided into two factors by exploratory factor analysis. The here-and-now sensory reliving quality appeared to reveal the nature of the first factor, the dissociative reliving sensation-based memory representation. The repetitive and broken visual experiences reflected the nature of the second factor, the fragmented visual experience memory representation. In relationship with posttraumatic psychological symptoms, hierarchical regression analyses controlling for demographic variables and variables related to trauma experiences showed that the dissociative reliving sensation-based memory representation explained PTSD and depressive symptoms significantly. The fragmented visual experience memory representation explained PTSD reexperience symptoms only. Severe traumatic experiences such as torture can be activated into predominant sensation-based memory representations, and the TMQQ appears to reflect these qualities well. Since dissociative reliving sensation-based memory representations are related to posttraumatic psychological symptoms, including depression, results of this study suggest the need for therapeutic interventions that target the integration of these memory representations.
