C-S, Symptomatic; C-R, remitted; NC, non-clinical; SAPS, Scale for the Assessment of Positive Symptoms (Andreasen, 1984); SANS, Scale for the Assessment of Negative Symptoms (Andreasen, 1983); AANEX, Appraisals of Anomalous Experiences Interview (Brett et al. 2007).
a
All scores for SAPS and SANS items are global scores.
b
C-R significantly higher than NC.
