Despite many decades of discussion about the impact of skewed responses on self-report personality trait evaluations, a consensus has not yet emerged. These controversies appear greater when evaluating antisocial tendencies. Social desirability may partly explain distortion in self-report instruments. The objective of this research was to cross-reference information resulting from two evaluation situations with self-report measures. From a sample of 156 participants, authors investigated possible changes in test scores in the case that participants needed to deliver response protocols to the researchers. The results revealed partial score changes in approximately one-third of the sample, indicating the need for further research using the same methods. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the relationship between psychopathy and the manifestation of interpersonal behaviors in 23 detainees, in a metropolitan area prison. The Hare PCL-R, which is used for the diagnosis of psychopathy, and the Interpersonal Measure of Psychopathy (IM-P), which is used for the measurement of interpersonal behavior expressed by participants in the interaction with the interviewer, were applied simultaneously by independent evaluators. The results showed statistically significant correlations between the total scores of the PCL-R and the IM-P, between the total scores of the IM-P and the factor 1 of the PCL-R, and a non-significant correlation with factor 2, indicating that the IM-P may be considered an auxiliary instrument for psychopathy assessment.
