Demographic and Clinical Predictors of Persistence in Patients Treated With Aripiprazole Once-monthly in Italy

Study Overview
=================
Brief Summary
-----------------
This is an observational, retrospective, non-interventional study that will include schizophrenic patients who were initiated with aripiprazole once-monthly as per normal clinical practice at least 6 months before the data collection starts (inclusion visit), and is designed to evaluate demographic and clinical predictors of persistence with this treatment. Data from each patient will be collected after informed consent is signed (inclusion visit), and will include retrospective information from the start of aripiprazole once-monthly treatment initiation (index date) until the follow-up/inclusion visit (minimum of 6 months after the index date). Data will be retrospectively collected from all visits occurring as per clinical practice (usually once monthly).
