A Study on the Efficacy of Virtual Reality Exposure Therapy (VRET) for Survivors of Childhood Sexual Abuse and War Related Trauma

Not Applicable

• Conditions: Posttraumatic Stress Disorder (PTSD); Depression
• Interventions: Behavioral: VRET; Behavioral: TAU

• Registration Number: NCT02234076
• Lead Sponsor: Erasmus Medical Center

Brief Summary

Background: Childhood Sexual Abuse (CSA) and combat related war-trauma are associated with posttraumatic stress disorder (PTSD) and depression. PTSD is one of the most prevalent Diagnostic and Statistical Manual of Mental Disorders (DSM) axis 1 disorders for which psychotherapy is widely practiced. Depression is one of the most common co morbid disorders when PTSD is diagnosed. Exposure to the traumatic memories or cues of the traumatic event often plays an important role in reducing symptoms of PTSD. Also symptoms of PTSD and depression have been related to a reduced specificity in autobiographical memory.

Objective: This study will examine the efficacy of a Virtual Reality Exposure Therapy (VRET) in a CSA and war related trauma sample by comparing it with treatment as usual (TAU). It will also attempt to develop protocols to implement this new technology into clinical practice and collect data to develop a treatment progress prediction model.

Study design: A randomized controlled intervention study.

Study population: 144 individuals with memories of CSA or war related trauma and symptoms of PTSD and/or depression.

Intervention: VRET or TAU.

Arm && Interventions

Group	Intervention	Description
VRET	VRET	Virtual Reality Exposure Therapy (VRET) The experimental treatment VRET is offered with the Multi-Modal Memory Restructuring System (3MR system) and a therapy manual. Participants can use this system at home. Note: The 3MR system is offered via a computer screen, no head-mounted display (HMD) equipment is used in this study.
TAU	TAU	Treatment As Usual

Primary Outcome Measures

Name	Time	Method
Posttraumatic Stress Disorder (PTSD) Checklist Diagnostic & Statistical Manual of Mental Disorders (DSM) 5 (PCL-5) to measure change from baseline self-reported symptoms of PTSD at the endpoint of the therapy (after completing 12 sessions) and follow-ups	At pre (baseline), post (after 12 therapy sessions with a minimum of 6 weeks and a maximum of 12 weeks), and follow-up (3 and 12 months post treatment) measurements	The PCL-5 is a brief assessment that identifies the presence and symptom severity of PTSD. We use the PCL-5 to measure self-reported symptoms of PTSD.
Beck Depression Inventory-II (BDI-II) to measure change from baseline self-reported symptoms of depression at the endpoint of the therapy (after completing 12 sessions) and follow-ups	At pre (baseline), post (with a minimum of 6 weeks and a maximum of 12 weeks), and follow-up (3 and 12 months post treatment) measurements	The BDI-II is a self-report questionnaire which measures the severity of depression in 21 statements, with four levels of increasing severity each. We use the BDI-II to measure self-reported symptoms of depression.

Secondary Outcome Measures

Name	Time	Method
The Outcome Questionnaire-45-2 (OQ-45-2) to measure change from baseline self-reported symptoms and well-being at the endpoint of the therapy (after completing 12 sessions) and follow-ups	At pre (baseline), post (with a minimum of 6 weeks and a maximum of 12 weeks) and follow up (3 and 12 months post treatment) measurements	The OQ-45-2 is a questionnaire which measures well-being in three domains; symptom distress, interpersonal functioning and social role. We use the OQ-45-2 to measure improvement in well-being in participants as addition to the symptom checklists, and to make a useful translation of the research data into clinical practice.
