About this study
Official title: Effect of Eye Movement Desensitization and Reprocessing Therapy 2.0 Online Group Protocol on Traumatic Experiences Based on Traffic Accident: A Randomized Controlled Trial
In this study, it will be investigated the efficacy of Eye Movement Desensitization and Reprocessing Therapy 2.0 Online Group Protocol on post-traumatic symptoms compared to control group. Therefore, the randomized control trial is based on Eye Movement Desensitization and Reprocessing Therapy 2.0 group as an intervention.
Read the detailed description
Eye Movement Desensitization and Reprocessing Therapy is an evidence-based psychotherapy approach, and it is proven as efficient in primarily post-traumatic symptom disorder. EMDR 2.0 is a new approach which is used for the cases that are not answering the standard EMDR protocols. According to the recent studies, both EMDR and EMDR 2.0 show a greater decrease in emotionality and vividness in similar time based on session numbers (Matthijssen, 2021). Also, it is found that EMDR 2.0 requires lower set numbers (shorter sessions) compared to EMDR.
In this study, it will be investigated the efficacy of EMDR 2.0 Online Group Protocol on post-traumatic symptoms compared to control group. Therefore, the randomized control trial is based on EMDR 2.0 group as an intervention. Compared to previous EMDR 2.0 individual settings, this study is based on a group protocol made by our team. This group protocol has been tested in a pilot study on volunteer mental health professionals. The results of this pilot study showed that EMDR 2.0 group protocol was successful, and investigators decided to begin the randomized control trial research.

What is being measured
The primary outcome is the main question the study is designed to answer.
The Depression, Anxiety and Stress Scale - 21 Items (DASS-21)
Depression, stress and anxiety scores will significantly change. Scores for depression, anxiety and stress are calculated by summing the scores. The scores are between 0-3, and more scores mean worse results.
for the relevant items
Measured: 1-week and 1-month follow-up
Impact of Events Scale Revised (IES-R)
Intrusion and hyperarousal scores will significantly change. The maximum mean score on each of the three subscales is '4', therefore the maximum 'total mean' IES- R score is 12. Lower scores are better.
Measured: 1-week and 1-month follow-up

Questions about this trial
What is this clinical trial studying?
A study testing EMDR 2.0 group protocol and Mhgap stress module in people with Post Traumatic Stress Disorder, run by Academy of Therapeutic Sciences, Turkey at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 9 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The Depression, Anxiety and Stress Scale - 21 Items (DASS-21) (time frame: 1-week and 1-month follow-up). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05596903, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 May 2023.
