3.1. Sample characteristics
Mean score of the total PANSS was 85.10 (SD¼18.80;
range¼48–126). Mean score on the positive scale was 21.25
(SD¼7.02; range¼7–36). Mean score on the negative scale was
21.87 (SD¼6.41; range¼7–34). Mean score on the general psychopathology
scale was 41.68 (SD¼9.49; range¼23–66). This
means that the severity of positive and negative psychopathology
in this patient sample was moderate, and that the general
psychopathology in this sample was low. Because we also assessed
self-reported persecutory ideation using the PIQ, we also calculated
the positive PANSS scale score minus item 6 which measures
ideas of persecution. The mean score of this measure was 17.73
(SD¼5.94; range¼6–30). Mean score on the PIQ was 14.88
(SD¼11.78; range¼0–39).
