 Results of backward stepwise regression using the full set of variables of the BPRS. Eight items of the BPRS as independent variables were positively associated with the CGISCH score as a dependent variable, and four items were inversely associated with the CGISCH score. Fvalue < 2.000 as a criterion for removal (p < 0.001). Rsquared was 0.7524 (p value of analysis of variance was less than 0.001), unstandardized β, standardized β, and the p value are shown.
