Recently I have been reviewing several articles related to psychopathy outside the forensic area and I have observed that a very popular questionnaire in a college setting is the Psychopathic Personality Inventory(PPI). So far I have not been able to find this questionnaire explicitly.
As far as I understand, the questionnaire was developed in this paper Psychopathic Personality Traits and Somatization: Sex Differences and the Mediating Role of Negative Emotionality by Scott O. Lilienfeld and Tanya H. Hess, 2001.
I was wondering if you could tell me where I can find the questionnaire?
I would appreciate it very much, thank you.
