First Pilot RCT of Episodic-Buffer-Oriented P-CRP for Adults Complex Loss and Trauma

Zahide Betül Baydar·interventional·Posted Jan 22, 2026·Updated Feb 25, 2026

In Brief

A clinical study evaluating Psychological-cognitive reprocessing procedure (P-CRP). and Expressive Narrative and Symbolic Drawing (ENSD) for Trauma and Stress Related Disorders and 2 related conditions. Completed, enrolled 43 participants across 1 site.

Detailed Summary

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.

Interventions

Psychological-cognitive reprocessing procedure (P-CRP).behavioral

Unlike traditional approaches, the traumatic imagery is not directly targeted in the first session. The intervention begins with the silent repetition of a word or phrase representing the core negative belief associated with the traumatic experience. . During each 1-minute set, bilateral stimulation (synchronized tapping on the shoulders only) is applied, allowing the client to process the traumatic material through spontaneously emerging associations selected by the mind itself. Rather than relying on external direction, the protocol activates internal self-regulation capacities. In this respect, it aims to promote semantic and symbolic reorganization, differing from classical cognitive restructuring or desensitization-based methods. The decision about which aspect of the experience will be processed or desensitized is determined by the client's own mental flow, thereby reinforcing a sense of trust in the mind's capacity despite the traumatic history.

Expressive Narrative and Symbolic Drawing (ENSD)behavioral

Following initial anamnesis and psychoeducation, clients recounted their trauma and drew a self-selected symbol of the event using their non-dominant hand. Each session involved discussing the memory and updating this symbol to facilitate indirect processing through creative expression.
