The Implicit Association Test and its difficulty(ies): Introducing the test difficulty concept to increase the true-score variance and, consequently, the predictive power of implicit association tests.

= 480) were analyzed using multigroup structural equation models. Again, the IAT closer to moderate difficulty had more true-score variance and predictive power than the IATs of extreme difficulty. Accordingly, for correlational research, we recommend developing moderately difficult IATs to maximize IAT true-score variance and provide suggestions on how to achieve that.
