Psychopathy
Canadian psychologist Robert Hare developed the
Psychopathy Checklist-Revised (PCL-R) in the 1990s to determine whether a person had psychopathy.
According to a
2014 articleTrusted Source, while healthcare professionals would classify only 1% of the population with psychopathy using Hare’s checklist, approximately 20% of people in prison in North America would meet the criteria for psychopathy.
ASPD and psychopathy share many symptoms. However, additional signs that may indicate that a person has psychopathy include:
- lack of empathy
- arrogance
- charisma
- excessive vanity
- lack of guilt
- difficulty processing other people’s facial expressions
- goal-oriented behavior
