Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Abstinent time of Methamphetamine addict | up to 84 days | The outcome was the confirmed abstinence during 12 weeks. Confirmed abstinence was defined as a negative urine drug test. The following aggregate measures of urine drug test results were calculated: the time-to-first positive urine test, the Treatment Effectiveness Score (TES; the sum of the number of METH-free urine samples submitted per participant ), the longest period of MA abstinence during the 84 days. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time (day) to first psychosis relapse from baseline to 84 days | up to 84 days | psychosis assessement was made once a week.Psychotic symptom relapse was defined as one or more of the following: (1) hospitalization for psychotic symptoms; deliberate self-injury or violent behavior, or suicidal or homicidal ideation that was clinically significant;25% increase in PANSS total score;for patients who scored \>40 at randomization, or a 10-point increase for patients who scored ≤40 at randomization for two consecutive assessments (within 1 week), and (4) increase in prespecified individual PANSS items scores (P1, P2, P3, P6, P7 and G8) to ≥5 for patients whose score was ≤3 at randomization, or to ≥6 for patients whose score was 4 at randomization for two consecutive assessments (within 1 week) |
| Change from baseline in CGI-S scores at 84 days | up to 84 days | general condition assessment was made by CGI-S once a week, and calculated the total scores |
| Change from baseline in Visual Analogue Scale (VAS) at 84 days | up to 84 days | Methamphetamine craving assessment was made by VAS once a week, and calculated the total scores |
| number of treatment day which calculated from randomization to the last visiting point | up to 84 days | record the follow up time |
