Secondary traumatization in refugee care-EMDR intervention for interpreters (STEIN): a study protocol for a quasi-randomized controlled trial.

BACKGROUND

By the end of 2022, more than 100 million people worldwide fled their homes. Before, during and after their flight, refugees have high risk of experiencing traumatic events. Accordingly, around every third refugee is affected by posttraumatic stress disorder. For adequate mental health care, the service of interpreters is often urgently needed to overcome existing language barriers. However, repeated exposure with details of traumatic narratives, as experienced by interpreters, can be burdensome and can lead to trauma sequela symptoms in terms of secondary traumatic stress. Only few studies have examined the treatment of secondary traumatic stress to date. Based on the recommendations for the treatment of posttraumatic stress disorder with confrontational methods, this study was designed to evaluate the effectiveness of an eye movement desensitization and reprocessing (EMDR) intervention in a sample of interpreters working in refugee care suffering from secondary traumatic stress symptoms.

METHODS

To evaluate the effectiveness of an EMDR intervention for the treatment of secondary traumatic stress symptoms, a quasi-randomized controlled trial using a waiting group design will be performed. Participants will be treated with a maximum of 6 sessions based on EMDR standard protocol. Primary outcome is the symptom load of secondary traumatic stress, assessed with the Questionnaire for Secondary Traumatization, while secondary outcomes comprise further symptom complexes such as PTSD due to self-experienced traumatic events, depression, anxiety, and somatization as well as quality of life, quality of professional life, and psychological wellbeing that will be assessed with the PDS, PHQ-9, GAD-7, SSD-12, SF-12, PROQOL-5, and WHO-5, respectively.

DISCUSSION

Our primary interest is to determine the efficacy of an EMDR intervention in interpreters affected by secondary traumatic stress, especially how many sessions are needed for significant symptom reduction. Change of associated symptom complexes and quality of life will be investigated. Reprocessing one's own stressful experiences may also contribute to this, which is not the focus of the treatment but relevant to the EMDR protocol. This study aims to assess if EMDR could be an acceptable, effective, and time-efficient method for reducing work-related secondary traumatization.
