PPI-R: Factor Structure in a Diverse Subclinical Sample

<p>Literature examining the factor structure of the Psychopathic Personality Inventory – Revised (PPI-R) has yielded mixed results. This study attempted to examine the three proposed factor structures (one-, two-, or three-) for the PPI-R utilizing a mixed gender undergraduate sample. Results demonstrated poor fit for each of the three proposed factor structures within the present sample. Post-hoc exploratory factor analysis of the PPI-R items revealed that seven of the eight original subscales from the measure were found to be salient. Rebellious nonconformity was the only subscale that was not able to be extracted. Furthermore, only 81 out of the 131 measure items loaded saliently onto each factor. These findings suggest that subscale scores be utilized, in addition to factor scores, when measuring psychopathic traits, as expression of psychopathy may differ depending on sample characteristics.</p>
