The Referential Thinking Scale as a Measure of Schizotypy: Scale Development and Initial Construct Validation

This article describes the development of a measure of schizotypic referential thinking. The authors present a 34-item questionnaire that includes a wide variety of referential thoughts and experiences, including both simple and guilty ideas of reference. The Referential Thinking Scale (REF) displays adequate internal consistency and strong relations with other measures of Schizotypy, such as the well-known Perceptual Aberration and Magical Ideation Scales. Item-level factor analysis of the REF suggests that referential thought is multidimensional in nature, including both simple and guilty ideas of reference components. The REF displays minimal relations with acquiesencc, social desirability, and sex. The REF does not appear to assess normative personality constructs that involve heightened self-awareness such as self-monitoring, self-consciousness, or social desirability, nor does it appear to be unduly related to psychological state variables. The REF was developed in order to provide an additional Schizotypy measure for use in large-scale screening efforts and other schizotypy studies.
