Dimensional scores of the PPS according to disease severity.
Dimensional sub scores are expressed as percentage of the maximum possible score in the dimension (as indicated in Table 1, far left column). Comparisons (Student's t tests) were made between the two sub-groups defined by the extreme values of the Clinician Global Impression of disease severity (CGI-ds) in the overall study population. CGI Borderline/Mild illness (score 1–2) n = 93, dotted line; CGI Severe/extremely severe illness (score 5–6) n = 142, solid line. ns: not significant at p<0.003 with Bonferroni correction.
