Resumo
The aim of the experimental work described in this dissertation was the study of m Brazilian adaptation of Eysenck's Maudsley Personality Inventory regarding introversion-extraversion dimension. The Brazilian version by Professor Riva Bauzer was twice administered to 70 students of four of our classes of psychology at the Colégio Batista Shepard. Besides this, to the same students a questionnaire was administered in which we asked to each pupil to give his subjective evaluation of the degree of extraversion present in each of his classmates. We were thus enabled to evaluate experimetally: a) the reliability coefficient of the questionnaire; b) the reliabiliy coefficient of the Brazilian version of the Maudsley Personality Inventory; c) the validity coefficient of the Maudsley Personality Inventory, taking the questionnaire as a criterion. Our work was not limited to this. The discriminating ability of each item of the Maudsley Personality Inventory was determined by means of the biserial correlation coefficient. together with the percentage of responses indicative of extraversion. The various experimental data now available open the way to further research aimed at the improvement of the Brazilian version of the Maudsley Personality Inventory.
