EMDR Versus Imagery Rescripting for Trauma-Related Intrusions

Summary

The goal of this clinical trial is to investigate the effectiveness and mechanisms of action of trauma treatments in a sample of patients meeting criteria for posttraumatic stress disorder (PTSD), unipolar depression, or both disorders. The main questions it aims to answer are:

* which first line treatment (Eye Movement Desensitization and Reprocessing \[EMDR\] vs. Imaginary Rescripting \[IR\]) works better for intrusive experiences in patients with PTSD, patients with a depression, and patients who meet criteria for both diagnoses.
* which mechanisms of action cause the treatment effects.

Participants will

* be randomly assigned to a standard treatment of EMDR or IR
* complete daily questionnaires measuring the outcome measures two weeks before the start of their treatment, during their EMDR or IR treatment, and for one month after their treatment.
* complete questionnaires measuring the outcome measures and secondary outcome measures at pre-intervention, post-treatment (i.e., 4 weeks after the last intervention session, at the end of the withdrawal phase), and at 6-month follow-up.

Interventions

BEHAVIORAL

Eye Movement Desensitization and Reprocessing

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.

BEHAVIORAL

Imagery Rescripting

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.
