N2 - The authors compared college students identified by high scores on the Magical Ideation Scale (M. Eckblad and L.J. Chapman, 1983) and the Revised Social Anhedonia Scale (MagSoc; n = 28; M. Eckblad. L.J. Chapman. J.P. Chapman, and M. Mishlove, 1982) with control participants (n = 20) at a 10- year follow-up assessment in an attempt to replicate L.J. Chapman, J.P. Chapman, T.R. Kwapil, M. Eckblad, and M.C. Zinser's (1994) report of heightened psychosis proneness in MagSoc individuals. The MagSoc group exceeded the control group on severity of psychotic-like experiences; ratings of schizotypal, paranoid, and borderline personality disorder symptoms; and rates of mood and substance use disorders. Two of the MagSoc participants but none of the control participants developed psychosis during the follow-up period (a nonsignificant difference). Consistent with L.J. Chapman et al.'s findings, the groups did not differ on rates of personality disorders or relatives with psychosis.
