We examined the psychometric properties and construct validity for a Minnesota Multiphasic Personality Inventory–2 Schizophrenia Proneness ( SzP ) scale (Bolinskey et al., 2001) and provided normative statistics. Premorbid participants were offspring of parents with schizophrenia‐related illness (SRI), with comparison groups of offspring of parents with major affective disorders and offspring of normals. Postmorbid participants were twins affected with SRI; their unaffected relatives served as a comparison group. Results suggest that an SzP T score of 65 or above is an effective indicator of personality processes associated with increased liability to developing SRI. © 2003 Wiley Periodicals, Inc.
