SPQ-BR Normative Data
Introducing the SPQ-BR
The Schizotypal Personality Questionnaire - Brief Revised is a 32-item revision of the original SPQ developed by Adrian Raine and colleagues. The SPQ-BR was optimized for a hierarchical factor structure: comprising 3 super-ordinate factors (i.e., positive, negative, disorganized) and 7 sub-ordinate factors (i.e., reflecting key facets of schizotypal personality traits).
