Creativity Training and the Stability and Internal Consistency of the Kirton Adaption-Innovation Inventory

Abstract

In his 1986 analytic review of the first ten years of research on adaption-innovation theory, Mudd commented on the importance of continued research on the Kirton Adaption-Innovation Inventory. Suggestions pertinent to the present study involved an examination of the stability of the instrument as well as the test-retest reliability of the full scale and subscales. A Lindquist Type III analysis of variance was used to examine the influence of creativity training on the stability of the Kirton full scale scores. The scores did not change after training. There was, however, a significant effect for gender by pre- and posttest interactions for the full scale scores. Men's full scale scores were higher than women's, and only men exhibited an increase. The women's pre- and posttest scores appeared more stable. Internal reliability coefficients and test-retest reliability coefficients for both the full scale scores and the subscale scores were very adequate, but the men's scores did increase.
