Comparing Eye Movement Desensitization and Reprocessing EMDR and Cognitive Therapy for PTSD in Norwegian Specialist Care A Randomized Trial for Adults with Post-Traumatic Stress Disorder

What this Trial Is About

Researchers are comparing two main therapies for post-traumatic stress disorder PTSD called eye movement desensitization and reprocessing EMDR and cognitive therapy for PTSD CT-PTSD. This large, long-term study aims to understand how well these treatments work in Norwegian specialist health care. The study will look at how these therapies affect PTSD symptoms, other related disorders, complex PTSD symptoms, and how patients function after treatment. It will also explore the role of the therapeutic relationship and long-term effects over time. Participants will be randomly assigned to receive either EMDR or CT-PTSD, each following a set treatment plan of up to 24 weekly therapy sessions. If no clear improvement is seen after 10 sessions, treatment may be stopped. EMDR focuses on processing trauma memories while using bilateral stimulation to reduce distress, while CT-PTSD uses cognitive techniques like restructuring thoughts and controlled exposure to trauma memories. Both therapies are provided in line with patient treatment goals. During the study, patients will complete digital questionnaires before treatment and after each therapy session to report symptoms of PTSD, depression, anxiety, psychosis, substance use, and functional outcomes. Researchers will monitor changes in PTSD symptoms from the start to the end of treatment at 24 weeks, with follow-ups at 3, 6, and 12 months. They will also assess effects on comorbid illnesses, functional outcomes, and the quality of the therapeutic alliance. The study lasts over a year, including treatment and follow-up assessments.
