RELIABILITY AND FACTORIAL VALIDITY OF THE WALLACH‐KOGAN CREATIVITY TESTS

The Wallach‐Kogan tests of ‘creativity’ and the Primary Mental Abilities test were administered to 207 university students. The creativity tests were scored for originality, and KR20 reliabilities calculated. Intercorrelations among the five creativity tests were also calculated and compared with those among the six ‘intelligence’ tests. Results indicated that the Wallach‐Kogan tests were highly reliable, clustered strongly among themselves, and correlated poorly with the intelligence tests. A factor analysis indicated the existence of large loadings of creativity tests on the intelligence factor, and of intelligence tests on the creativity factor.
