N2 - The predictive validities of several indicators of psychosis proneness were evaluated in a 10-year longitudinal study (N = 508). As hypothesized, high scores on the Perceptual Aberration Scale, Magical Ideation Scale, or both (n = 182), especially those who initially reported psychoticlike experiences of at least moderate deviance, exceeded control subjects (n = 153) on psychoses (revised 3rd edition of the Diagnostic and Statistical Manual of Mental Disorders), psychotic relatives, schizotypal symptoms, and psychoticlike experiences at follow up. Ss who initially scored high on the Magical Ideation Scale and above the mean on the Social Anhedonia Scale were especially deviant. The Physical Anhedonia Scale and the Impulsive Nonconformity Scale were not effective predictors of psychosis proneness.
