1. INTRODUCING SD3: A SHORT MEASURE OF THE DARK TRIAD Delroy L. Paulhus & Daniel N. JonesUniversity of British Columbia • INTRODUCTION • The Dark Triad consists of three overlapping but distinct personality constructs. • Standard measures (SRP: 64 items; Mach: 20 items; NPI: 40 items) are 124 items long. • The goal was to finding an acceptable, reliable, valid short form that also mirrors each of the original concepts. • Sample details • A total of 739 subjects were collected from Amazon’s Mechanical Turk – a new and reliable source of adult data (e.g., Buhrmester, Kwang, & Gosling, in press) • All participants were primarily European Heritage with a mean age of approximately 30 years. • Measures used: • Short Dark Triad (Jones & Paulhus, in prep) • SRP (Paulhus, Neumann, & Hare, in press) • NPI (Raskin & Hall, 1979) • Mach-IV (Christie & Geis, 1970) • IPIP-IPC (Markey & Markey, 2009) • Overclaiming Questionnaire (Paulhus et al., 2003) • STUDY 1 – FACTOR STRUCTURE • Short Dark Triad (SD3) Factor structure • SRMR = .08 TLI = .88 • DISCUSSION • The 40-item SD3 has an acceptable factor structure with solid internal consistencies for each subscale. • SD3 scales are highly correlated with the original D3 measures and evenly predict the facets of the those original measures. • The locations of the SD3 in the Interpersonal Circumplex match those of the original scales • Among the SD3, overclaiming correlates highest with narcissism , psychopathy to a lesser extent, and Mach not at all , thereby replicating previous findings using original measures (e.g., Paulhus & Williams, 2002). • Using a behavioral indicator, Machiavellianism was positively associated with delay of gratification whereas psychopathy was negatively. • In sum, the SD3 inventory provides a short but reliable instrument that demonstrates predictive, criterion, and concurrent validity. • REFERENCES: • Christie, R., & Geis, F.
