Clinical Trial Summary

Background and study aims:

The Eye Movement Desensitization and Reprocessing Group Protocol with Children (EMDR-GP/C) was first developed by Korkmazlar following the Marmara earthquake in Turkey in 1999 and can be adapted for different populations. The aim of this study is to assess if a EMDR-GP program may help primary school students in improving narrative complexity and specificity of autobiographical memories, as well as their subjective unit of distress (SUD) and validity of cognition (VoC).

Who can participate? Students attending the fourth or fifth year of primary school

What does the study involve? Participants will be randomly assigned to the experimental and control groups. Participants in the experimental group will undergo a 3-week EMDR-GP with weekly 60-minute group sessions (3 sessions), while the control group will follow routine daily school activities.

Questionnaires will be used to assess narrative complexity, specificity of autobiographical memories, SUD and VoC before and after the intervention.

What are the possible benefits and risks of participating? Benefits of participating in the study may include an improvement of narrative complexity, specificity of autobiographical memories, and their SUD and VoC.

Intervention

Behavioral:
• Group EMDR
The eight phases of the adapted group EMDR protocol was administered during each session: 1. Meeting: Explaining the nature of trauma, group rules, name tags, filling in the scales. 2. Preparation: Exploring children's support system, explaining EMDR, safe place, resource exercise, and installation with bilateral stimulation (BLS, butterfly hug or knee tapping). 3. Assessment: Drawing the worst image on a small separate sheet of paper, SUD level, (negative cognition, emotions, body sensations - if possible). 4. Desensitization: It is done with drawing on 4 separate papers with BLS (butterfly hug or knee tapping). 5. Installation: With the healing story written according to the adaptive information processing (AIP) model, the installation is accompanied BLS. 6. Body scan: A positive body state is installed with the relaxation technique. 7. Closure & future template: Strong closure with artwork. 8. Re-evaluation: if possible.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Event coding - Pre-intervention	Event coding is measured using Manual for Coding Events in Self Defining Memories. "Relationship" nominal score means a better outcome	Event coding is measured before the 3-week group EMDR intervention
Primary	Memory specificity level - Pre-intervention	Memory specificity level is measured using Classification System and Scoring for Self-defining Autobiographical Memories. "Specific" nominal score means a better outcome	Memory specificity level is measured before the 3-week group EMDR intervention
Primary	Narrative complexity level - Pre-intervention	Narrative complexity level is measured using Coding System for autobiographical Memory Narratives in Psychotherapy. Higher scores mean a better outcome.	Narrative complexity level is measured before the 3-week group EMDR intervention
Primary	Subjective Unit of Distress - Pre-intervention	Subjective Unit of Distress is measured using a self-reporting scale with a 0- to 10-point rating scale. Higher scores mean a worse outcome	Subjective Unit of Distress is measured before the 3-week group EMDR intervention
Primary	Validity of Cognition - Pre-intervention	Validity of Cognition is measured using a self-reporting scale with a 1- to 7-point rating scale. Higher scores mean a better outcome	Validity of Cognition is measured before the 3-week group EMDR intervention
Primary	Event coding - Post-intervention	Event coding is measured using Manual for Coding Events in Self Defining Memories. "Relationship" nominal score means a better outcome	Event coding is measured after the 3-week group EMDR intervention
Primary	Memory specificity level - Post-intervention	Memory specificity level is measured using Classification System and Scoring for Self-defining Autobiographical Memories. "Specific" nominal score means a better outcome	Memory specificity level is measured after the 3-week group EMDR intervention
Primary	Narrative complexity level - Post-intervention	Narrative complexity level is measured using Coding System for autobiographical Memory Narratives in Psychotherapy. Higher scores mean a better outcome.	Narrative complexity level is measured after the 3-week group EMDR intervention
Primary	Subjective Unit of Distress - Post-intervention	Subjective Unit of Distress is measured using a self-reporting scale with a 0- to 10-point rating scale. Higher scores mean a worse outcome	Subjective Unit of Distress is measured after the 3-week group EMDR intervention

Secondary	Autobiographical memory definition - Pre-intervention	Autobiographical memory definition is measured using Coding System for Autobiographical Memory Narratives in Psychotherapy. "Autobiographic" nominal score means a better outcome.	Autobiographical memory definition is measured before the 3-week group EMDR intervention
Secondary	Memory integration level - Pre-intervention	Memory integration level is measured using Classification System and Scoring for Self-defining Autobiographical Memories. "Integrated" nominal score means a better outcome	Memory integration level is measured before the 3-week group EMDR intervention
Secondary	Autobiographical memory definition - Post-intervention	Autobiographical memory definition is measured using Coding System for Autobiographical Memory Narratives in Psychotherapy. "Autobiographic" nominal score means a better outcome.	Autobiographical memory definition is measured after the 3-week group EMDR intervention
