Some observations concerning the reliability of the Pressey X-O test

Abstract

306 men and women, mostly sophomores, were given the Pressey X-O Form A, part of the group taking it twice, three months apart. Pronounced sex differences were found, the women in general tending to dislike more things than the men; there is some deviation from the original norms. The reliability scores for the separate tests range from 0.15 to 0.58, with the total affectivity score at 0.48 and the idiosyncrasy score at 0.39. The total scores correlate with intelligence measures and academic grades below 0.20 in all cases except idiosyncrasy vs. freshman grades (0.61). The intercorrelations of the parts of the tests are between 0.20 and 0.43. Evaluations in terms of net differential score are suggested, and the test is recommended as a clinical instrument.
