Brief Summary:

This project focuses on the under-researched group of individuals who develop psychotic episodes of short duration (less than four weeks) while using substances. This includes individuals diagnosed with psychotic disorder not otherwise specified (PNOS) or substance-induced psychotic disorder (SIP) AND substance abuse or dependence. Very little is known about the most appropriate maintenance/relapse prevention management of these subjects. These individuals are not diagnosed with a primary psychosis because psychotic symptoms are too short-lived or non-specific, the onset of substance use precedes the onset of psychotic symptoms and the subject has not experienced sufficient psychotic symptoms in the absence of substance use. However, previous studies have shown that they are at high risk of recurrence of psychotic symptoms. Thus, this project will assess the efficacy of the second-generation antipsychotic aripiprazole for maintenance treatment of subjects who had a recent psychotic episode of short duration associated with substance use. The investigators will compare aripiprazole and placebo for preventing the recurrence of psychotic symptoms and decreasing substance use during a 6-month maintenance phase.

Outcome Measures

Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :

1. Psychotic Symptoms [ Time Frame: 7 months ]
   Psychotic symptoms wil be assessed with the Structured Interview for Prodromal Symptoms and the Brief Psychiatric Rating Scale. We will focus on time to first recurrence of psychotic symptoms and rate of recurrence.
2. Frequency/amount of substance use [ Time Frame: 7 months ]
   Frequency and amount of cannabis and other substance use will be recorded with the Timeline Follow-Back Method. We will focus on time to first recurrence of substance use and rate of recurrence.

Secondary Outcome Measures :

1. Mood symptoms [ Time Frame: 7 months ]
   Mood symptoms will be assessed with the Hamilton Depression Rating Scale
2. Adverse Events [ Time Frame: 7 months ]
   Adverse events will be assessed with the Systematic Assessment for Treatment Emergent Events interview, Simpson-Angus Scale for Extrapyramidal Symptoms, the Abnormal Involuntary Movement Scale, the Barnes Akathisia Scale, and blood tests (fasting glucose, insulin and lipid profile tests)
