Factor analyses of the NEO-PI-R Inventory and the Comrey Personality Scales in Italy and the United States

The Costs and McCrae NEO-PI-R Inventory and the short form of the Comrey Pe rsonality Scales (CPS) were administered to volunteer samples in Italy and the United States. In each sample, the 30 NEO-PI-R facet scales defining Ne uroticism, Extraversion, Openness, Agreeableness, and Conscientiousness wer e intercorrelated and factor analyzed. In the American sample, all five NEO -PI-R factors were well defined. In the Italian sample, only three of these factors were well defined. The five NEO-PI-R factor scores and the eight C PS scale scores were intercorrelated and factor analyzed in each sample sep arately to show the overlap between these two instruments. Four factors wer e found in the American data and five in the Italian data. Good corresponde nces were shown in both samples between NEO Extraversion and CPS Extraversi on, NEO Neuroticism and the reverse of CPS Emotional Stability, as well as NEO Conscientiousness and CPS Orderliness. In both samples, NEO Agreeablene ss was related to both CPS Trust and CPS Empathy. An additional factor foun d only in the Italian data was defined by NEO Openness and the reverse of C PS Social Conformity. (C) 2000 Elsevier Science Ltd. All rights reserved.
