A General Factor of Personality in a sample of inmates: associations with indicators of life-history strategy and covitality

This study looked for a General Factor of Personality (GFP) in a sample of male convicts (N=226; mean age 32 years). The GFP was extracted from seven broad personality traits: FFM factors, Amoralism (the negative pole of the lexical Honesty-Humility factor) and Disintegration (operationalization of Schizotypy). Three first-order factors were extracted, labeled Dysfunctionality, Antisociality and Openness, and GFP was found through the hierarchical factor analysis. The nature of the GFP was explored through analysis of its relations with markers of fast Life-History strategy and covitality. The results demonstrated that the GFP is associated with unrestricted sexual behavior, medical problems, mental problems, early involvement in criminal activity and stability of criminal behavior. The evidence shows that the GFP is a meaningful construct on the highest level of personality structure. It may represent a personality indicator of fitness-related characteristics and could be useful in research of personality in an evolutionary context.
