Objective: Psychopathy and antisocial personality disorder (ASPD) are two constructs not interchangeable. Compared to the ASPD, psychopathy is characterized by lack of anxiety, low withdrawal, and high levels of attention seeking. %26lt;br%26gt;Method: The sample of this study included 76 subjects with a substance use disorder. Subjects were aged between 18 and 59 years old (M = 32.87, SD = 9.36). With respect to level of education 3 subjects are elementary school graduates, 49 have a middle school diploma, 21 own a high school diploma, and 3 participants have a bachelor%26apos;s degree. We administered the following measures: a) Psychopathic Personality Inventory-Revised (PPI-R); b) Psychological Treatment Inventory (PTI); c) 20-Item-Toronto Alexithymia Scale (TAS-20); d) Barratt Impulsiveness Scale (BIS). %26lt;br%26gt;Results: Most of the significant correlations between the Psychopathic Index (PPI-R total score), and the measures administered are listed below: PPI-R total score and Deviance (r = .482, p %26lt; .001), PPI-R total score and Hypomania (r = .369, p %26lt; .001), PPI-R total score and Unresolved attachment (r = .293, p %26lt; .001), PPI-R total score and Manipulativeness (r = .550, p %26lt; .001), PPI-R total score and the TAS-20 total score (r = .230; p %26lt; .001), PPI-R total score and Difficulty in Identifying Feelings (DIP) factor (r = .250, p %26lt; .001), PPI-R total score and Attentional Impulsiveness (r = .409, p %26lt; .001); PPI-R total score and Motor Impulsiveness (r = .526, p %26lt; .001). Results of MANOVAs between the two groups also revealed significant differences on several variables analyzed. %26lt;br%26gt;Conclusions: Our study showed that addicted subjects with psychopathic tendencies are more likely to experience negative emotions and have a peculiar cognitive style with respect to antisocial addicts. These results partially confirm those ones of previous studies underlining that psychopathic population is generally characterized for a major need for stimulation, poor behavioral controls, lack of realistic long-term goals, impulsivity, irresponsibility.
