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.

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.

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.

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.

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.

At the beginning of the scale, four demographic questions are included (name, gender, age, and occupation). The instrument uses a four-point Likert-type response format. The State Anxiety subscale consists of 20 items rated on a scale from (1) Not at all to (4) Very much so. The Trait Anxiety subscale also contains 20 items, with response options ranging from (1) Almost never to (4) Almost always. Cronbach's alpha coefficients reported in the Turkish adaptation were α = .72 for the State Anxiety subscale, α = .67 for the Trait Anxiety subscale, and α = .70 for the total scale; overall reliability values for the instrument have been reported to fall between α = .60 and α = .80.
