N2 - Our study investigated the convergent and discriminant validity of five of Chapman's Schizotypia Scales (i.e., Physical Anhedonia, Revised Social Anhedonia, Perceptual Aberration, Magical Ideation, and Impulsive Nonconformity; L. J. Chapman, J. P. Chapman, & Raulin, 1976, 1978; Eckblad & L. J. Chapman, 1983) and Meehl's Schizoidia Scale (Meehl, 1964) within a sample of 50 personality disordered subjects, many of whom possessed schizotypic traits. It was hypothesized in part that all five of the Chapman scales and the Schizoidia Scale would correlate with the schizotypal personality disorder; the Physical Anhedonia and Revised Social Anhedonia Scales would correlate with the schizoid personality disorder, whereas the Magical Ideation and Perceptual Aberration Scales would not; the Physical and Revised Social Anhedonia Scales would not correlate with the avoidant personality disorder; and the Impulsive Nonconformity Scale would correlate with the borderline and antisocial personality disorders. Only the hypotheses concerning the avoidant personality disorder and the Schizoidia Scale were not supported. The findings remained even when the effects of state anxiety and state depression were controlled. Implications of the findings with respect to the validity of the Chapman and Schizoidia Scales and the personality disorders are discussed.
