Psychopathy is a personality disorder characterized by a lack of empathy for others. The LSRP was developed in 1995 for use in psychological research. It measures on two scales: primary psychopathy (psychopathic emotional affect) and secondary psychopathy (psychopathic lifestyle).
The test consists of twenty six statements that could possibly apply to you. You must rate each on how much you agree with it on a scale of (1) strongly disagree (2) disagree (3) neither agree nor disagree (4) agree (5) strongly agree. Most people will will complete the test in five minutes or so.
