The Psychopathic Personality Inventory (PPI-Revised) is a personality test for traits associated with psychopathy in adults. The PPI was developed by psychologists Scott Lilienfeld (now at Emory University) and Brian Andrews to comprehensively index the personality traits without assuming particular links to anti-social or criminal behaviors. It is a self-report scale developed using non-clinical samples (e.g. university students) that can also be used with clinical samples (e.g. prisoners). It includes measures to detect impression management or careless responding. The PPI was revised in 2005 to become the PPI-R (Lilienfeld & Widows) and now comprises 154 items organized into eight subscales. The items are grouped into two overarching and largely separate factors, plus a third factor that is mainly dependent on scores on the other two: I: Fearless dominance. From the subscales Social influence, Fearlessness, and Stress immunity. Associated with less anxiety, depression, and empathy as well as higher well-being, assertiveness, narcissism, and thrill-seeking. II: Impulsive antisociality. From the subscales "Machiavellian" egocentricity, Rebellious nonconformity, Blame externalization, and Carefree lack of planning. Associated with impulsivity, aggressiveness, substance use, antisocial behavior, negative affect, and suicidal ideation. III: Coldheartedness. From a subscale with the same name. A person may score at different levels on the different factors, but the total score indicates the overall extent of psychopathic personality. Higher scores on factor I are associated with emotional stability and social efficacy, as well as reduced empathy. Higher scores on factor II are associated with maladaptive tendencies, including aggressiveness, substance use problems, negative feelings and suicidal ideation. Scores on the two major factors tend to be only moderately correlated. The Psychopathy Checklist—revised (PCL-R) is another test used to assess psychopathy, developed in and intended for forensic settings. An analysis of the two measures on community samples or prisoners indicates that these tests assess partially different concepts of psychopathy. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Psychopathic Personality Inventory」の詳細全文を読む スポンサード リンク
