To examine the quality of life (QoL) and clinical outcomes for Asian schizophrenic outpatients treated with olanzapine or haloperidol. Patients were randomized to 24-weeks' treatment with either olanzapine (n = 144) or haloperidol (n = 132) in a double-blind, prospective, multi-country study. The QLS and WHO-BREF were assessed for QoL; the PANSS, BPRS and CGI scales for clinical status; the BAS, AIMS and SAS scales for physical dysfunction.
