Abstract

This study aimed to examine whether intrusive memory and experiential avoidance mediate the relationship between sensation-based memory representation and complex post-traumatic stress symptoms in adults aged 19 to 39 who have experienced complex trauma. Data from 314 participants who reported emotional, physical, and sexual violence on two or more occasions were analyzed using structural equation modeling. The results indicated that sensation-based memory representation directly influenced complex post-traumatic stress symptoms, and indirectly affected these stress symptoms through the sequential mediation of intrusive memory and experiential avoidance. This study confirms that intrusive memory and experiential avoidance mediate the relationship between sensation-based memory representation and post-traumatic symptoms. By focusing on complex post-traumatic stress symptoms, this research enhances our understanding of memory-related issues and offers valuable therapeutic insights for individuals with complex post-traumatic stress. Lastly, the limitations of the study were discussed.
