Health Evaluation of Abilify Long-term Therapy (HEALTH)

• Change from baseline in CGI-S scale at each visit during the first 39 weeks treatment. [ Time Frame: Throughout the study ]
• Change from baseline in total score on the Brief Psychiatric Rating Scale (BPRS) at each visit during the treatment period. [ Time Frame: Throughout the study. ]
• Change from baseline in total score on WHOQOL-BREF questionnaire at each visit during the treatment period. [ Time Frame: Throughout the study. ]
• Change from baseline in total score on PANSS (optional) questionnaire at each visit during the treatment period. [ Time Frame: throughout the study ]
• Change from baseline in total score on SFS (optional) questionnaire at 12 and 52 weeks treatment. [ Time Frame: Throughout the study. ]
• Change from Visit 2 on POM questionnaire at each visit during the 12-week switching period. [ Time Frame: Throughout the study. ]
• CGI-I scores after 12, 26, 39, and 52 weeks of treatment. [ Time Frame: Throughout the study. ]

This is a post-market surveillance, and the treatment to patients will be depended upon the decision based on physician's clinical judgment. The health profiles during the switching period, after 12 weeks short-term use, and after 52 weeks long-term use of aripiprazole will be recorded and evaluated.
