Study Overview
Brief Summary
This study will evaluate the clinical effectiveness ofthe Immersive Virtual Reality alongside exprosure and response Prevention (ERP) Treatment in cognitive-Behavioral Therapy for Obsessive-compulsive Disorder, and the underlying neural mechanism by electroencephalography (EEG) and eye-tracking methodology .
Detailed Description
The current study aims to the clinical effectiveness of the Immersive Virtual Reality alongside exprosure and response Prevention (ERP) Treatment in cognitive-Behavioral Therapy for Obsessive-compulsive Disorder. 30 OCD patients whose symptom were mainly associated with "contamination/clean" , "Symmetry/precision", "Examination" and "Sex" will be randomized into two groups (i.e. VR ERP or ERP). The treatment will be performed twice a week for the first two weeks. And for the next 4 week, the treatment for OCD patients will be undertook once a week. There will be 8 times in total. The investigators will assess thhe OCD patients'symptom severity in the baseline, 2 weeks, 4weeks and after 8 weeks of the whole combined treatment. Through the study, Yale-Brown Obsessive Compulsive Scale（Y-BOCS）, the Obsessive Compulsive Inventory-Revised (OCI-R), the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), Perceived Stress Scale (PSS), Pittsburgh sleep quality index (PSQI) and side-effect questionnaire will be obtained by a trained investigator. The patients will also get individual's data of EEG and eye-movement.

Arms & Interventions
VR(ERP）
The combination of exposure and response prevention (ERP) and VR will be applied twice a week for the fist two weeks. For the next four weeks, this treatment will be applied once a week. 8 times in total
Intervention: The combination of exposure and response prevention (ERP) and VR (Combination Product)
traditional ERP
The traditional ERP will be applied twice a week for the fist two weeks. For the next four weeks, this treatment will be applied once a week. 8 times in total
Intervention: Traditional ERP (Behavioral)
Outcomes
Primary Outcomes
Change in Yale-Brown Obsessive Compulsive Scale(Y-BOCS) score
Time Frame: from baseline to 8weeks
It assesses the severity of OCD symptoms. The Y-BOCS scale ranges from 0 to 40, with 0 being no symptoms and 40 being severe.The responder on Y-BOCS is defined as a Y-BOCS decrease at least 35% from the baseline at post-treatment.
Secondary Outcomes
- Change in Beck Depression Inventory(BDI)(from baseline to 8weeks)
- Change in Obsessive Compulsive Inventory-Revised(OCI-R)(from baseline to 8weeks)
- Chinese version of Working Alliance Inventory-Short Form (WAI-SR)(assessed only once after the entire treatment at the end of the eighth week. (at the end week 8 ))
- Change in Beck Anxiety Inventory (BAI)(from baseline to 8weeks)
- Simulator Sickness Questionnaire(SSQ)(The SSQ should be assessed each time after the VR+ERP treating for OCD patients. (at week 2, 3, 4, 5, 6, 7))
