Study Overview
Brief Summary
The purpose of this research is to develop an objective assessment based on the virtual reality techniques which is used for evaluate addiction severity.
Detailed Description
In order to evaluate the addiction severity and the effect of rehabilitation objectively, this study develops a virtual environment model based on the virtual reality technique, making the subjects in a drug related or neutral scene , at the same time recording the physical signs and eye movements index. Reliability and validity of this system will also be tested in this study. And we will construct the norm of addiction assessment system in Shanghai .The evaluating system will be very beneficial to develop novel and practical assessment for synthetic durg related disorder, and provide a reference for other drug dependence diagnosis.

Outcomes
Primary Outcomes
Changes of physiological indexs
Time Frame: In 1 year
The physiological index including galvanic skin response、encephlogram and electromyogram will be used to evaluate the reliability and validity of the virtual reality based addiction assessment system, and construct the norms of assessment system as well.
Changes of eye movement index
Time Frame: In 1 year
The eye movement index will be used to evaluate the reliability and validity of the virtual reality based addiction assessment system, and construct the norms of assessment system as well.
Secondary Outcomes
- Addiction Severity Index(ASI)(baseline)
- The Diagnostic and Statistical Manual of Mental Disorders（DSM）(baseline)
