Note 1: A series of linear regressions were computed to examine the variance accounted for by positive and negative schizotypy (T1) in predicting psychopathology, personality and functioning at T3; maximum likelihood estimation and bootstrap procedures (with 2 000 samples) were employed.
Note 2: According to Cohen [44], f 2 values above .15 are medium and above .35 are large effect sizes.
