This project sought to determine the relationship between the Jesness Inventory (JI) and the Psychopathy Checklist-Youth Version (PCL-YV) in sample of incarcerated adolescents. The adolescents were male juvenile offenders incarcerated at a mid-western juvenile correctional facility. Upon intake, data were collected for psychopathy, along with data related to juvenile delinquency. Using Pearson product moment correlation analysis, correlation coefficients were examined to determine the degree of concurrent validity between the PCL-YV and the JI. Using factor analysis, the factor structure for the Psychopathy Checklist-Youth Version and the Jesness Inventory was derived and factor scores were computed. Using Pearson product moment correlation analysis, correlation coefficients among the factor scores were compared to determine the pattern and degree of covariation between the PCL-YV and the JI. A discriminant function analysis was performed to predict the ability of the JI factor scores to identify youth who scored 30 or above on the PCL-YV Specifically this study sought to examine the patterns of covariation between the PCL-YV and the JI and to determine if the two instruments are assessing similar or different constructs. Another purpose of this study was to assess the possibility of utilizing the JI as a screening instrument for low vs. high psychopathic traits in order to reduce the administration of the PCL-YV, thus providing for a more cost effective method of assessing this most dangerous population in our institutional settings.Data from this study suggest that the JI and the PCL-YV are not assessing similar constructs. Additionally, the data suggest that the JI does not predict psychopathic traits in adolescent incarcerated males.
