Neutrosophic Scale to Measure Psychopathic Personalities Based on Triple Refined Indeterminate Neutrosophic Sets
註釋The psychopathic personality is the disorder of the personality characterized by antisocial behavior, lack of empathy and cruelty of the individual. This type of personality is not simple to diagnose. It is not possible to differentiate with certainty a psychopathic individual from one who is not. One measure to evaluate psychopathy is the Triarchic Psychopathy Measure (TriPM), consisting of three sub-scales that measure boldness, meanness, and disinhibition. This measure uses a Likert-type scale with 4-points. However, due to the complexity that characterizes measuring this type of personality, TriPM may be inaccurate, because four points are used instead of five. Therefore, the scale consisting of true, mostly true, mostly false, and false was modified to a new one with five elements, where indeterminacy is added. Another contribution of this paper is that the four numerical elements are replaced by a scale based on Triple Refined Indeterminate Neutrosophic Sets, where the person instead of measuring the item having a single numerical value with 100% of certainty, uses five elements with certainty between 0% and 100%. Accuracy is essential in this topic, where indeterminacy is present since psychopathy definition. Additionally, the method is illustrated with an example. Psychopathy evaluation is very important in forensic psychology, since these individuals can be involved in criminal acts.
