A Study to Observe the Safety and Tolerability of Paliperidone Palmitate (Invega Sustenna) in Korean Schizophrenic Patients

Number of participants with adverse events up to Week 25

Time frame: Up to Week 25

Change from baseline in Clinical Global impression-Severity (CGI-S) scale scores

The CGI-S rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants". Higher scores indicate worsening.

Time frame: Baseline (Day 1), Week 5, Week 9, Week 13, Week 17, Week 21, and Week 25

Change from baseline in Personal and Social Performance (PSP) scale scores

This PSP assesses the degree of a participants dysfunction within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, and disturbing and aggressive behavior. The score ranges from 1 to 100, divided into 10 equal intervals to rate the degree of difficulty (i, absent to vi, very severe) in each of the 4 domains. Based on the four domains there will be one total score. Participants with a score of 71 to 100 have a mild degree of difficulty; from 31 to 70, varying degrees of disability; =\< 30, functioning so poorly as to require intensive supervision.

Time frame: Baseline (Day 1), Week 5, Week 9, Week 13, Week 17, Week 21, and Week 25
