Despite the growing interest in investigating how psychopathic traits differ in Majority Culture non-criminal samples, relatively less attention has focused on how ethnic minorities differ in these psychopathic traits. The Psychopathic Personality Inventory- Revised (PPI-R) measures psychopathic personality traits. The PPI-R allows for easier data-gathering while increasing our understanding of common psychopathic personality tendencies.

The American Indian Bicultural Inventory - Northern Plains (AIBI-NP) is a 23 item, Likert scaled questionnaire yielding two subscale measures for cultural identification in two distinct, theoretically unrelated cultures. The AIBI-NP was normed on Northern Plains American Indians, who were represented in this study. The primary purpose of this study aims to expand the general knowledge of the eight PPI-R subscales, while also investigating the degree to which cultural identification might impact PPI-R scores. PPI-R scores were collected from 72 American Indian participants using different means to recruiting participants such as the University of North Dakota (UND) SONA Research Participation system, a tribal college in North Dakota, through flyers and word of mouth at the UND American Indian Student Services (AISS) and the annual Pow-Wow dance and ceremonies. Overall the results showed that cultural identification did not impact PPI-R subscale scores when the four groups scores were compared in the sample.
