(a) This is the two-factor model with the items of the Revised Social Anhedonia (RSAS) and the Perceptual Aberration (PER) scales independent and two factors, namely, positive schizotypy and negative schizotypy, correlated in schizophrenia patients. Note: PERf1, PERf2, and PERf3 refer to the three parcels of the PER scale; RSASf1, RSASf2, and RSASf3 refer to the three parcels of the RSAS scale. This figure shows the results of a confirmatory factor analysis, whereby the three parcels of the Magical Ideation Scale (MIS) and PER scales load on the positive schizotypy factor, and the three parcels of the RSAS and the three parcels of the Revised Physical Anhedonia Scale (RPAS) load on the negative schizotypy factor. This two-factor model corresponds with the original theory underlying the construction of the Chapman psychosis–proneness scales. The correlation coefficient between the positive schizotypy and negative schizotypy factors is 0.36. (b) This is the two-factor model with the items of the RSAS and the PER scales independent and two factors correlated in first-degree relatives of schizophrenia patients. The correlation coefficient between the positive schizotypy and negative schizotypy factors is 0.59. (c) This is the two-factor model with the items of the RSAS and the PER scales independent and two factors correlated in non-clinical young adults. The correlation coefficient between the positive schizotypy and negative schizotypy factors is 0.38.
