Exploratory and confirmatory factorial structure of the MCMI-III personality disorders: overlapping versus non-overlapping scales. European Journal of Psychiatry, 22, 49-58. https://doi.org/10.4321/S0213-61632008000200001 http://hdl.handle.net/11268/539The aim of this study was to explore the factorial structure of the 14 Personality Disorder (PD’s) scales of the MCMI-III for the overlapping and non-overlapping scales, independently. Previous exploratory studies using different factor extraction procedures inform that the structure of MCMI-III personality disorders has between 2 and 4 factors. The present study used a large sample of 674 non-clinical subjects divided at random in two groups: a) calibration, and b) validation. In the calibration group, principal component analysis with orthogonal rotation was carried out, obtaining 2, 3 and 4 factors for the overlapping and non-overlapping scales independently. In the validation group, the three models were compared using confirmatory factorial analysis techniques. The exploratory and confirmatory results indicate that the 4-factor solution is the most plausible. Although the congruence coefficients between non-overlapping and overlapping scales in the 4-factor solution were higher, confirmatory factor analysis showed that models designed from overlapping scales did not fit well to data.engjournal article10.4321/S0213-61632008000200001 open accessPsiquiatría
