Abstract. Around 4,100 British adults completed the NEO-PI-R (Costa & McCrae, 1985), which measures the Big Five Personality factors at the Domain and the Facet level, as well as the Hogan Development Survey (Hogan & Hogan, 2009) measure of Paranoid Personality Disorder called Sceptical. This study sought to validate this measure by comparing NEO facet correlational results with other studies. The Sceptical score from the HDS was the criterion variable in the correlations and multiple regressions. Sceptical people were Disagreeable, Neurotic, and Conscientious. Facet analysis showed them low on Trust, Compliance, and Straightforwardness but high on Depression and Angry Hostility. Limitations of the study are discussed.
