简要总结
The purpose of this retrospective study was to evaluate the effectiveness of a new psychotherapy technique called Psychological Cognitive Reprocessing Procedure (P-CRP) in treating trauma symptoms. The P-CRP intervention was developed and manualized by the principal investigator (Z.B.Baydar). Participants were randomly assigned to either the P-CRP intervention group, an active control group, or a waitlist condition. The study aimed to determine if this new method, which focused on episodic buffer processing, significantly reduced trauma-related psychological distress compared to standard approaches. Data collected during the intervention phase were analyzed to assess the efficacy of the P-CRP technique.

研究组 & 干预措施
Expressive Narrative and Symbolic Drawing (ENSD)
Control participants received four session a narrative-based expressive and symbolic drawing protocol. The intervention delivered to the control group can be characterized as an active, experiential, projective, and sensory-supported approach.

Psychological-cognitive reprocessing procedure (P-CRP).
The P-CRP was the experimental group receiving four session the intervention. The Psychological-Cognitive Reprocessing Procedure (P-CRP) is a brief and a neuro-psychological intervention based on the episodic buffer model. This process facilitates the separation of cognitions from automatic processing and pulls traumatic fragments into the episodic buffer through simultaneous neuronal firing. This integration helps resolve the semantic fragmentation caused by trauma, allowing for cognitive reintegration and meaning making.

Waitlist Group
Participants in this group did not receive any active psychological intervention during the study period. They completed the pre-test and follow-up assessments at the same time intervals as the intervention groups. Following the completion of the follow-up phase, participants in the wait-list group were offered a psychological intervention protocol based on the study's findings to ensure ethical treatment standards.
结局指标
主要结局
The Impact of Event Scale -Revised (IES-R)
时间窗: Baseline (Week 0), Post-intervention (Week 6), and Follow-up (Week 10) .
The IES-R is a 22-item self-report scale designed to assess the psychological impact of traumatic experiences across three subdimensions: intrusion, avoidance, and hyperarousal. Items are rated on a 5-point Likert scale (0 = not at all to 4 = extremely) based on symptom frequency over the past seven days. Total scores range from 0 to 88, where higher scores indicate greater severity of post-traumatic stress symptoms. According to the literature, scores of 33 and above suggest a probable PTSD diagnosis. The Turkish adaptation was used, which demonstrated high validity and reliability.
