What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Antipsychotic treatment discontinuationOther
Withdrawal of antipsychotic medication to stabilized patients.
Maintenance antipsychotic treatmentOther
Maintenance antipsychotic medication to stabilized patients.
| Study group | Role | What they receive |
|---|---|---|
| Intervention group | Experimental | Antipsychotic treatment discontinuation (DT) Receives: Other: Antipsychotic treatment discontinuation |
| Control group | Active comparator | Maintenance antipsychotic treatment (MT) Receives: Other: Maintenance antipsychotic treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Relapse rate.
The main outcome was the percentage of relapse/exacerbation in the two groups of patients, discontinuation and maintenance.
Measured: At 3 years.
Secondary outcomes (3)
Clinical psychopathology.
Clinical psychopathology differences between groups are evaluated by the mean change from the study intake to 3 years for the severity of Clinical Global Impression scale (CGI), Brief Psychiatric Rating Scale expanded version of 24 items (BPRS), Scale for the Assessment of Positive Symptoms (SAPS) and Scale for the Assessment of Negative Symptoms (SANS) total scores.
Measured: At 3 years.
Time to relapse.
Time to relapse in the two groups of patients, discontinuation and maintenance.
Measured: At 3 years.
Clinical functionality.
Measured: At 3 years.
