Discussion
Both ATTA scores—Creative Ability and Creativity Level—proved to be adequate predictors of creative performance as measured by Campaign Creativity.The unadjusted validity coefficients of .59 and .56 are comparable to the average validity coefficient of I.Q. predicting job performance as reported in the literature (see Hunter & Hunter, 1984). Of practical importance, the results suggest that using the ATTA Creative Ability measure alone (subskills only, and thus briefer to score) is sufficient. On the other hand, the ATC Creative Ability measure was not a good predictor. In light of the distinction pointed out by Arthur and Villado
, it seems likely that the ATC and the ATTA are measuring the same construct—creative ability—but that the self-rating method of the ATC is much less predictively valid. Accordingly, in Study 2, we proceeded only with the ATTA.
