The purpose of this research is to develop an objective assessment based on the virtual reality techniques which is used for evaluate addiction severity.
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.
Study Type
OBSERVATIONAL
Enrollment
1,500
The patients who used the amphetamine type stimulants will be diagnosed by the chief physician、associate chief physician or attending physician first to evaluate their addiction severity. And then the patients will finish the test in the virtual environment, at the same time their eye movement index and other physiological data will be recorded .Physiological data includes cardiac rate、galvanic skin response and electroencephalogram and so on.The test will proceed at the beginning of withdrawl、3 months later、 6 months later and 1 year later and record the information synchronously.
The healthy controls will finish the test in the virtual environment, at the same time their eye movement index and other physiological data will be recorded .Physiological data includes cardiac rate、galvanic skin response and electroencephalogram and so on.The test will proceed at the baseline and 1 month later and record the information synchronously.

Changes of physiological indexs
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.
Time frame: In 1 year
Changes of eye movement index
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.
Time frame: In 1 year
