Abstract

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 SzPT score of 65 or above is an effective indicator of personality processes associated with increased liability to developing SRI.
