The Psychopathy Checklist, developed by Dr. Robert Hare, is a psychological assessment tool used to evaluate the presence of psychopathic traits in individuals. It consists of 20 items that assess various personality traits and behaviors, such as superficial charm, lack of empathy, and impulsivity. Each item is scored on a scale, helping professionals determine the degree of psychopathy. This checklist is often used in forensic settings to assess criminal behavior and risk of reoffending. It aids psychologists and psychiatrists in understanding the psychological profile of individuals, contributing to treatment planning and risk management in cases involving criminal justice and mental health.
