Experimental: Modified prolonged exposure (add on)

The psychological intervention modified Prolonged Exposure Therapy (mPE) is applied, in addition to Treatment as usual (TAU) (that is, an Add-on). mPE is a trauma-focused evidence-based cognitive behavioral therapy (CBT) shown to be effective in treating PTSD. We will use imaginal exposure in the sessions with the patient describing the traumatic event in detail while being recorded for later listening and homework, and in vivo exposure for visiting specific places or people. Psychoeducation and controlled breathing exercises play a secondary role in PE. We have adapted the mPE to the current SAC settings in Norway where nurses or social workers, not psychologist, as a rule are performing the psychosocial follow-up for rape victims. In this project we plan for three to five once or twice weekly nurse-/social worker-led mPE interventions, given early after the assault.

No_intervention: Treatment as usual (TAU)

Standard care at the sexual assault center (SAC), that is mostly nurse-/social worker-led psychoeducation at varying intervals and extent, and medical follow-up at the SAC.
