Notes: Factor-1: Negative symptoms (N1 social anhedonia; N2 avolition; N3 expression of emotion; N4 experience of emotions and self; N5 ideational richness). Factor-2: Global functions (N6 occupational functioning; Current-GAF; GAF drop, GAF score baseline from highest in the past year). Factor-3: Disorganized communication and behavior (P5 disorganized communication; N5 ideational richness; D1 odd behavior or appearance; D4 impaired personal hygiene; G3 motor disturbances). Factor-4: General symptoms (G1 sleep disturbance; G2 dysphoric mood; G4 impaired tolerance to normal stress). Factor-5: Odd thoughts (P1 unusual thought content; D2 bizarre thinking). Factor-6: Distorted cognition and perception (P2 suspiciousness; P4 perceptual abnormalities).
