The present study investigated the relation between Machiavellianism and intimacy attitudes in the interpersonal relationships. Male (N = 46) and female (N = 56) participants aged 18 to 51 years (M = 31.56, SD = 8.00) were recruited to complete a questionnaire containing Mach IV Scale (Christie & Geis, 1970) and Intimacy Attitude Scale-Revised (Amidon, Kumar, & Treadwell, 1983). The regression analysis has revealed that Machiavellianism is a reliable predictor of the intimacy attitude of an individual, and the hypothesis that Machiavellianism is negatively correlated with positive intimacy and positively correlated with negative intimacy has been confirmed.
