简要总结
In Hong Kong, less than 5% of stimulants abusers were reported to misuse these substances via injection. Also, it is well known that patients with co-morbid substance abuse/dependence and psychosis or schizophrenia-related disorders are prone to earlier treatment discontinuation and high oral medication non-adherence, resulting in poorer overall outcomes. With the recent availabilities of the 4-weekly long-acting injectable form of aripiprazole, and the 4-weekly and the 3-monthly long-acting injectable form of paliperidone palmitate, on the background of the surging phenomenon of stimulant misuses in Hong Kong, it is a timely opportunity to conduct an early pharmacotherapy intervention study to offer an evidence-based strategy aiming to stop individuals with substance use disorders with psychosis to develop into a more chronic disabling dependence or co-morbid state.

结局指标
主要结局
Efficacy on psychosis as measured by the Brief Psychiatric Rating Scale - 24 items (BPRS-24)
时间窗: at 12th and at 24th months
The efficacy for controlling stimulant associated psychosis for subjects receiving the active treatments with paliperidone and aripiprazole as compared to treatment as usual is measured by BPRS. The lowest score of BPRS-24 is 24. The lower the score of BPRS refers to better efficacy in controlling psychosis.
次要结局
- transition from diagnosis of substance induced psychosis to Schizophrenia as defined by DSM-5(24 months)
- change in stimulant use disorder as defined by DSM-5(At 12th month and at 24th month)
- Montreal Cognitive Assessment (MoCA)(At 12th month and at 24th month)
- Addiction Severity Index (ASL)-lite(At 12th and 24th months)
