A Computer Adaptive Test (CAT) for knowledge of parent management skills: Prototype development and preliminary psychometrics.

The Knowledge of Effective Parenting Test (KEPT) is a measure of parent management skills that was developed as an outcome measure for clinical trials of psychosocial treatments for disruptive behavior disorders. In the current study, we developed a computer adaptive test (CAT; KEPT-CAT) prototype and compared it to the full item bank (21 items; KEPT-Full) and to a brief static version (10 items; KEPT-Brief) using simulations from a large (N = 1,570) nationally representative dataset. Results showed that the KEPT-CAT prototype (median = 8 items) was slightly more efficient than the KEPT-Brief and had a significantly higher (p < .001) correlation with scores from the full item bank (r = .97) than the KEPT-Brief (r = .94). The KEPT-CAT prototype has additional advantages over the static KEPT-Brief, including the potential selection of different items from one administration to the next. This flexibility can reduce practice effects that might result from repeated administration of the same fixed items. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
