What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Abstinent time of Methamphetamine addict

    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.

    Measured: up to 84 days

Secondary outcomes (4)
  1. Time (day) to first psychosis relapse from baseline 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)

    Measured: up to 84 days

  2. Change from baseline in CGI-S scores at 84 days

    general condition assessment was made by CGI-S once a week, and calculated the total scores

    Measured: up to 84 days

  3. Change from baseline in Visual Analogue Scale (VAS) at 84 days

    Methamphetamine craving assessment was made by VAS once a week, and calculated the total scores

    Measured: up to 84 days

  4. number of treatment day which calculated from randomization to the last visiting point

    record the follow up time

    Measured: up to 84 days
