"This study is designed to test the equivalency of the paper format of the Psychopathic Personality Inventory-Revised (PPIR) with a computerized (online) version. It is hypothesised that the psychometric properties of the PPI-R would continue to hold when the administration format was changed from paper to computer. Participant scores are found to be similar. 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 computerised format also allows for both more efficient scoring (i.e., no hand coding) and more complete responding (i.e., less missing data)." [Sub required]
