Brief Summary

Rape is a common cause of post-traumatic stress disorder (PTSD) among women, as around 30-50% will develop PTSD in the aftermath of rape. A modified protocol based on Prolonged Exposure Therapy (mPE), has been developed, consisting of three to five once or twice weekly 60 minutes sessions, and studies indicate that if implemented early after rape, mPE may prevent the development of PTSD. The aim of the study is to conduct a multi-site (4 Sexual assault care centers in Norway) randomized control trial (RCT) in which patients are recruited early after rape, and randomized to intervention (mPE) or treatment as usual (TAU).

Outcome Measures

Primary Outcomes (2)

  • PTSD Checklist for DSM-5 (PCL-5)

    The PCL-5 is a self-report questionnaire consisting of 20 items corresponding to the 20 symptoms of PTSD as defined by DSM-5. Patients rate their posttraumatic symptoms on a Likert scale from 0-4. The continuous sum score of the PCL-5 will de the primary outcome.

    At 3 months follow-up

  • PTSD Symptom Scale - Interview for DSM-5 (PSS-I-5)

    The PSS-I-5 is a clinician-administered diagnostic interview measuring the 20 symptoms of PTSD as defined by DSM-5.

    At 3 months follow-up

Secondary Outcomes (8)

  • Patient Health Questionnaire-9 (PHQ-9)

    At 6 weeks, 3, 6 and 12 months

  • General Anxiety Disorder-7 (GAD-7)

    At 6 weeks, 3, 6 and 12 months

  • Female Sexual Function Index (FSFI)

    At 6 weeks, 3, 6 and 12 months

  • Bergen insomnia scale (BIS)

    At 6 weeks, 3, 6 and 12 months

  • EQ-5D-5L

    At 6 weeks, 3, 6 and 12 months

  • +3 more secondary outcomes

Study Arms (2)

Modified prolonged exposure (add on)

EXPERIMENTAL

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.

Behavioral: Modified prolonged exposure

Treatment as usual (TAU)

NO INTERVENTION

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.

Interventions

Imaginary and in vivo expo, in addition to psychoeducation

Also known as: Brief intervention, cognitive behavioral therapy
Modified prolonged exposure (add on)

Eligibility Criteria

Age16 Years+
Sexfemale(Gender-based eligibility)
Gender Eligibility DetailsMany of the vaildated questionnaires are based on the presence of female genital organs, hence, we have chosen to include only genetical and phenotypical females
