Effect of Eye Movement Desensitization and Reprocessing Therapy 2.0 Online Group Protocol

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.

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.

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

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.

Inclusion Criteria: Being older than 18 Having a traffic accident between 6 months and 10 years Having necessary knowledge on using relevant technological devices Exclusion Criteria: Having mental deterioration after the accident Having a lower score of 7 on Adverse Childhood Experiences (ACEs) Having pre-existing psychotic disorder
