Brief summary
This study will test the safety of an aripiprazole injection in subjects with schizophrenia that are currently taking oral antipsychotic medication other than aripiprazole. Subjects in this study will receive one injection of aripiprazole and will need to stop taking their other antipsychotic medication two weeks after the injection. The study will last one month. Subjects will be required to come to a clinic for evaluations and drug and urine collection five times during the course of the study.

The OC dataset are participants who were evaluated at that visit on the efficacy variable under analysis (i.e. participants who had missing data due to drop out or other reasons were not included in the OC dataset).
