Gough and Heilbrun’s Adjective Check List and Cattell’s 16 Personality Factors Questionnaire an Analysis of Mutual Relations

Abstract

The aim of the article is to present mutual relations betwenn Cattell’s 16 PF and Gough and Heilbrun’s 39 ACL scales. Statistical analyses − redundancy analysis, analysis of canonical correlations, and Pearson’s r − were conducted on the data from 212 students (111 women and 101 men) of various faculties. It was found that on the basis of the results in Cattell’s 16 PF a maximum 30.2% of variance in the ACL could be explained, and on the basis of the results in the ACL scales a maximum 37.1% of variance in Cattell’s 16 PF could be explained. The multivariable mutual relations between the two methods were interpreted on the basis of five pairs of canonical variables. The cononical correlations were .83, .76, .70, .68 (with p<.001) and .62 (with p. .05) respectively. The highest correlations between the scales of the two methods reached .55, and there were many significant correlations with p<.001. It was found that the two methods, with about 1/3 of common variance, are not equivalent to each other. On the basis of canonical variables and correlations between the scales the relations were discussed between particular variables formulated in different theoretical contexts. The results of the analyses can be a source of inspiration to generate new diagnostic hypotheses in psychological interpretation of personality profiles obtained for subjects or groups in each of the tests.
