Associations of Machiavellianism and narcissism were examined in two samples (Ns = 214 and 205) via the Mach-IV and the Narcissistic Personality Inventory. Scores on these self-report measures were correlated. Machiavelianism scores were positively associated with aspects of narcissism which indicate maladjustment, i.e., entitlement and exploitativeness, and inversely associated with adaptive narcissistic tendencies, i.e., self-sufficiency. The discussion focuses on the relative adjustment of those scoring high on Machiavelianism.
