A psychometric evaluation of the revised P scale in delinquent and non-delinquent Spanish samples

A Spanish translation of the revised P scale was administered to a group of 300 prisoners and to a control group of 300 soldiers. The psychometric properties of the scale were similar to the ones obtained previously in various empirical studies. The scale showed a reasonable unidimensionality in both groups and the factor structure obtained were quite similar. Finally, the distribution and moments of the total scores were sensibly different in the various subgroups in agreement with the theoretical predictions.
