What Are the Core Features of Psychopathy? A Prototypicality Analysis Using the Psychopathy Checklist-Revised (PCL-R)

What are the core features of psychopathy? Previous prototypicality analyses showed that many features were considered as highly prototypical. The authors extend this work by using forced ranking to grasp which features are most important. Forensic mental health professionals ranked the 20 Psychopathy Checklist-Revised (PCL-R) items on their importance to psychopathy. Affective-interpersonal features were judged to be of greater importance than behavioral–lifestyle features. The most important items were callous/lack of empathy, conning/manipulative, and lack of remorse or guilt, which were deemed more important than nearly all other PCL-R features. The prototypicality ranking of the 20 PCL-R items by the forensic mental health professionals showed strong overlap (r = .64 to .86) with psychometric indices of item importance (network centrality, item-total correlation, and item response theory discrimination parameter). Taken together, these findings clarify the relative importance of PCL-R features to psychopathy.

Extending The Competitive Profile Matrix Using Internal Factor Evaluation And External Factor Evaluation Matrix Concepts

Internal Factor Evaluation and External Factor Evaluation matrices allow an organization to visualize their strengths, weaknesses, opportunities, and threats while a Competitive Profile Matrix utilizes critical success factors to allow an organization to compare itself to other competitors. The authors wondered if substituting basic internal strengths and weaknesses categories, and external opportunities and threats classifications for the conventional CSFs in a forced ranking method could extend the Competitive Profile Matrix to allow additional strategic understanding. The goal of extending the Competitive Profile Matrix using the forced ranking of important organizational factors when evaluating an organizations relative competitive position against major competitors was successfully realized. An External Competitive Profile Matrix (ECPM) and an Internal Competitive Profile Matrix (ICPM) better draw awareness to internal and external categories that need an organizations attention.
