Group type: EXPERIMENTAL
Intervention: Eye Movement Desensitization and Reprocessing
Description: In the EMDR condition, the Dutch version of the treatment protocol based on Shapiro's original work (2001) is followed. In the first session, the rationale of EMDR is explained. The patient describes the memory, and identifies the most aversive still image, the associated negative cognition, desired positive cognition, feelings, somatic sensations, and perceived tension, as measured by Subjective Unit of Distress (SUDs). Desensitization then begins by asking patients to focus on the still image while following the movement of a light bar or the therapist's fingers with their eyes (i.e., eye tracking task). Then, in the installation phase, the patient focuses on the positive cognition during the eye tracking task. When the validity of the positive cognition is 6 to 7 on a 7-point Likert scale, a body scan is performed to ensure that no unresolved traumatic material remains. Each session ends with a reflection and debriefing.

Intervention: Imagery Rescripting
Description: The IR condition, following Arntz and Weertman's (1999) protocol, addresses traumatic or aversive memories by creating alternative scenarios. In the first session, the method is explained. The patient describes their memory in the present tense, from the first-person perspective, and describes associated feelings, thoughts, and emotional needs. The therapist then seeks permission to 'enter' the scene, guiding the patient to visualise an alternative, emotionally satisfying course of events. This may involve the therapist or patient intervening in the situation, ensuring the patient's emotional needs are met. The patient then relives the memory from the point of view of their younger self, with the adult-self intervening in the scene. The process continues until all emotional needs are fulfilled. Generally, one trauma memory is rescripted per session. The initial IR session involves therapist-led rescripting, with subsequent sessions encouraging patient-led rescripting whenever possible.
