Robot-Assisted Intelligent Rehabilitation Treatment for Methamphetamine Use Disorders.

Study Overview
=================
Brief Summary
-----------------
The purpose of this research is to evaluate the efficacy and safety of Robot-assisted rehabilitation intelligent system as a virtual stand-alone treatment, delivered with minimal clinical monitoring compared with treatment as usual in methamphetamine (MA) use disorders.

Detailed Description
-----------------
Based on artificial intelligence technology, face recognition technology, virtual reality technology to develop an available Robot-assisted rehabilitation intelligent system. Then, using this intelligent system as a new way of Psychotherapy to provide treatment for methamphetamine patients, and compare it with traditional treatment to verify the efficacy and safety of Robot-assisted rehabilitation intelligent system in Chinese methamphetamine patients.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: robot-assisted rehabilitation intelligent treatment<br>Participants assigned to this condition were offered 10 weekly individual sessions of robot-assisted rehabilitation treatment, delivered by the Robot-assisted rehabilitation intelligent system. The system contains 10 core cognitive-behavioral therapy (CBT) skill topics (such as functional analysis, coping skills training, reviewing practice exercises, explaining CBT concepts). A robot therapist demonstrates the target CBT skills and assigns homework to participants. | Device: robot-assisted rehabilitation intelligent treatment<br>* robot-assisted rehabilitation psychotherapy<br>|
| Other: treatment as usual<br>Participants in the treatment-as-usual group were offered standard treatment at the compulsory isolated detoxification centers and non-compulsory isolated detoxification institutions, which consisted of weekly group and/or individual therapy, as determined by the clinical team. | Other: standard psychotherapy treatment<br>* standard treatment at the compulsory isolated detoxification centers and non-compulsory isolated detoxification institutions<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Changes of galvanic skin response during the virtual reality based addiction assessment system | The galvanic skin response is an emotional physiological indicator, and its unit is ohm. | in 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Treatment motivation | Using the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) to measure the treatment motivation of the participants. The score of the scale is between 19 and 95. The higher the score, the higher the treatment motivation. | in 1 year | 
| Anxiety | Anxiety is assessed by the State-Trait Anxiety Scale (SAS). The score of the SAS scale is between 0 and 80. The higher the score, the more severe the anxiety symptoms. | in 1 year | 
| Depression | Depression is assessed by the the Beck Depression Scale (SDS). The score of the SDS scale is between 0 and 80. The higher the score, the more severe the depression symptoms. | in 1 year | 
| Attentional bias related to drugs and emotional stimulation | The emotional Stroop tests is used for assessed attentional bias. The indicator is the accuracy rate of the key presses, from 0 to 100%. | in 1 year | 
| Risky decision-making | Balloon Analogue Risk Task is used for assess the risky decision-making ability. The indicator is the average number of balloon blows, and its unit is times. | in 1 year | 
| Reaction inhibition ability | Stop signal task is used for assess the reaction inhibition ability. The indicator is the reaction time when the participant completes the task, and its unit is milliseconds. | in 1 year | 
| Changes of electroencephalogram power spectrum during the virtual reality based addiction | The electroencephalogram power spectrum reflects the functional status of the brain, and its unit is uV^2. | in 1 year |
