Migration is a complex and stressful experience. Migrants often experience potential traumatic events (PTE) either in their home country (pre-migration), during migration, and/or after their arrival in the host country (post-migration). Migration and resettlement have been associated with various mental-health problems and psychiatric conditions, the prevalence of which varies across studies. Among the most common psychiatric disorders associated with migration, Post-Traumatic Stress Disorder (PTSD) (prevalence varying between 9 and 36% across studies) and Major Depressive Disorder (MDD) (prevalence varying between 5 and 44% across studies) raise particular concern, as they are associated with long-lasting functional impairment [Eye Movement Desensitization and Reprocessing (EMDR) is a psychotherapeutic approach, which was designed on the basis of the so-called adaptive information processing (AIP) model [EMDR was designed and used as an individual intervention in all the above-mentioned studies. Since clinicians require complementary training to apply this treatment, individual EMDR may not be the most time- and cost-efficient psychotherapy when a high number of patients need treatment in a short time frame. This is a critical issue when considering access to mental health care for migrants, especially in Europe where a large proportion of migrants who have arrived over the last years have been exposed to PTE. The high volume of mental health care needed and the large number of potential patients among migrants are challenging the access to mental health care systems in host countries [Thus, group EMDR, which could offer an effective treatment to a large number of people, may be more resource-efficient. Up to now, several EMDR group protocols have been developed, including Group Traumatic Episoderotocol (G-TEP) [Therefore, group EMDR has been gaining attention in the scientific literature in the past few years [
