    Mechanisms of the Formation and Involuntary Repetition of Trauma-Related Flashback: A Review of Major Theories of PTSD

    Ming Wang1, Jing Liu2,*, Qiwu Sun3,4, Wenzhen Zhu4

    International Journal of Mental Health Promotion, Vol.21, No.3, pp. 81-97, 2019, DOI:10.32604/IJMHP.2019.011010

    Abstract Trauma-related flashback is one of the typical symptoms of patients suffered from posttraumatic stress disorder (PTSD), which intrudes into the body and mind of patients uncontrobaly and repeatedly. Psychodynamic theories of mechanisms of the formation and involuntary repetition of trauma-related flashback establish a foundation for most cognitive theories of PTSD. Cognitive behavioral theories of PTSD, from the initial use of behavioristic principles (e.g., conditioning, alternative learning, generalization, etc.) to explain fear conditioning to the emphasis on the roles of cognitive and behavioral factors (e.g., cognitive model or schema, completion tendency, associative network, data-driven processing, analogue… More >

    Cognitive Intervention on the Flashback of Traumatic Event: Based on the Dual Representation Theory of PTSD

    Jing Liu1, Xuelian Chen1,*, Ming Wang2, Lin Cheng3

    International Journal of Mental Health Promotion, Vol.20, No.3, pp. 75-82, 2018, DOI:10.32604/IJMHP.2018.010857

    Abstract Flashback, related to the traumatic event, is a prominent symptom of posttraumatic stress disorder (PTSD). The dual representation theory (DRT) of PTSD emphasizes that the weakened contextual representation (C-rep), the enhanced sensory representation (S-rep) and the loss of connection between C-rep and S-rep play an important role in the formation and retrieval of flashback. DRT proposes that cognitive intervention tasks which inhibit S-rep or enhance C-rep can reduce flashbacks. And many studies have proved this theoretical hypothesis. In the future, simulation intervention studies should continue to strengthen, some clinical application studies should also be appropriately More >
