BPRS, Brief Psychiatric Rating Scale; MRSS, Morning Side Rehabilitation Status Scale; SDSS, Social Disability Screening Schedule
a Repeated measure ANOVA showed that the overall between-group difference in BPRS was not statistically significant (F=0.572, p=0.454)
b Within group differences in the MRSS score from June 2010 to June 2012 was significantly different in both short DUP group (t=3.31,p=0.004) and the long DUP group (t=3.87, p=0.001).
c Within group differences in the SDSS score from June 2010 to June 2012 was significantly different in short DUP group (t=2.17, p=0.040) but not in the long DUP group (t=1.19, p=0.250).
