Inventory (YPI), kriminella handlingar och attityder till kriminellt beteende bland gymnasieungdomar. En frågeställning som undersöktes i studien var, om det fanns något samband mellan YPI personlighetsdrag och kriminella handlingar. Ytterligare en frågeställning som undersöktes var om det fanns några könsskillnader i attityder gentemot kriminellt beteende. Studien utfördes med en kvantitativ datainsamlingsmetod, vilken genomfördes via tre frågeformulär. De tre frågeformulären somanvändes i studien var ett egetkonstruerat frågeformulär, Youth Psychopatich traits Inventory (YPI), vilket är ett självskattningsformulär, och ett modifierat frågeformulär från Brottsförebyggande rådet. Datan som samlades in var från 108 gymnasieungdomar i åldrarna 15-19 år, därav 34 killar och 56 tjejer. Resultaten visade på att det personlighetsdrag som var relativt högst självskattat i den undersökta gruppen var thrill-seeking. Resultaten visade även att det fanns positiva medelstarka signifikanta samband mellan fem av YPI variablerna (manipulation, remorselessness, thrill-seeking, impulsiveness, irresponsibility) och kriminella handlingar. Ytterligare resultat som studien visade var att fler killar än tjejer hade gjort någon eller några kriminella handlingar. Killarnas attityder var mer liberala gentemot kriminella handlingar än tjejernas, vilket även stöds av tidigare forskning / The purpose of the study was to examine personality traits according to the Youth Psychopathic traits Inventory (YPI), criminal acts and attitudes towards criminal behavior among high school students. One of the questions that have been examined in the study is if there is any correlation between young people that have been involved with criminal acts and young people that have YPI personality tendencies. Another question investigated in the study was if there are gender inequities between boys and girls with regard to the attitudes towards criminal behavior. The study was conducted through a survey that included three questionnaires. The results were compiled and compared and then analyzed using a computer-based algorithm. The three questionnaires that were used in the study were a self-constructed survey, the Youth Psychopathic traits Inventory (YPI) and finally one modified Crime prevention council-BRÅ survey. The test group consisted of 108 upper secondary youth between the ages of fifteen and nineteen. The 108 participants included 34 boys and 56 girls. The result clearly showed that the psychopathic tendencies that were represented amongst the youth in the study are thrill-seeking based. The results also showed strong significant correlation between five of the YPI, variables (manipulation, remorselessness, thrill-seeking, impulsiveness, irresponsibility and criminal acts. The study also showed that more boys than girls had been involved in criminal acts of some kind. The attitudes of the boys in the study showed that they had a more liberal views regards to criminal acts than the girls, which is supported in previous research

This study examined the predictive value of the three dimensions of youth psychopathic personality towards delinquency, on delinquency through the application of hierarchical regression analysis, while controlling for gender. Dimensions being: Callous/Unemotional-, Impulsive/Irresponsible-, and Grandiose/Manipulative traits. The study included 891 (48% female) Swedish adolescents from a community sample with a mean age of 14.28 (SD=.94) years. A self-report instrument was used to assess psychopathic traits in youth, the Youth Psychopathic Traits Inventory (YPI), consisting of 50 items and is specifically designed to lower the risk of response bias. Results: It was discovered that Impulsivity/Irresponsible behavior predicted statistically significant 14% of the variance in delinquency, and gender significantly predicted 4%. Callous/Unemotional predicted non-significant 0,3% and Grandiose/Manipulative predicted none of the variance in delinquency and was not significant. The findings regarding dimensions contradict the majority of research on the subject which has focused on CU-traits as main predictor of antisocial behavior, but in line with recent studies using a similar analytical approach showing Impulsivity/Irresponsible behavior as main predictor. The findings regarding gender are in line with previous research.
