Note. Standardized factor loadings of control group (outside parentheses) and schizophrenia-spectrum group (inside parentheses). UP = Unusual Perceptual Experiences; OB = Odd Beliefs or Magical Thinking; IR = Ideas of Reference; SP = Suspiciousness and Paranoia; CA = Inappropriate or Constricted Affect; NF = No Close Friends; SA = Excessive Social Anxiety; OS = Odd Thinking and Speech; EO = Odd or Eccentric Behavior; Uni = unidimensional; Corr. = correlated factor model; Hier = hierarchical factor model; Pos = positive symptom; Neg = negative symptoms; Dis = disorganized symptoms; Par = paranoid symptoms; 2nd order = specific factors loading on the second order general schizotypy factor. All loadings significant at p < .001.
