Computer equivalency of the psychopathic personality inventory-revised in a nonincarcerated population

This study is designed to test the equivalency of the paper format of the Psychopathic Personality Inventory-Revised (PPI-R) with a computerized (online) version. It is hypothesized that the psychometric properties of the PPI-R would continue to hold when the administration format was changed from paper to computer. A total of 124 respondents participate in the study. Participant scores on all 15 of the PPI-R scales are found to be similar, as are all internal scale consistencies. Test-retest reliabilities for scores on the PPI-R Overall Total, Factors, and Content scales range from r =.76 (Coldheartedness) to r =.93 (PPI-R Total). The computerized format also allows for both more efficient scoring (i.e., no hand coding) and more complete responding (i.e., less missing data).
