The Five-Factor Personality Questionnaire (CP5F) includes 130 items grouped in six scales. Five of them evaluate the superfactors of the Big Five model (Extraversion, Agreeableness, Conscientiousness, Emotional Stability and Authomomy), while the sixth assesses the participantsï¿½ tendency to give socially desirable answers (Social Desirability). This article presents the results of the correlation analysis among the CP5F scales and those resulting from the FFPI (Five-Factor Personality Inventory) and EPQ (Eysenck Personality Questionnaire) questionnaires and the comparative results among the average scores of the Social Desirability scale obtained in two situations regarding the management of the CP5F questionnaire: one in which the participants were motivated to build a favorable image of themselves (mandatory periodical psychological evaluations or professional selections) and another in which the participants had no reasons to be untruthful (they solved the questionnaire for personality diagnosis purposes, psychological intervention or willingly, for the standardization of the CP5F questionnaire). The CP5F scales reflect a good internal consistency, the ï¡ coefficients calculated in the two categories of situations, grouped according to sex and three age groups (20-25 years, 26-35 years and 36-45 years) ranging from .639 to .924.
