A Computerized Adaptive Test for the Knowledge of Effective Parenting Test-Internalizing Module: Instrument Validation Study.

Background: The development of efficient, scalable, and precise tools to assess knowledge of evidence-based parenting strategies is critical, particularly as increased parenting knowledge is a core target of many intervention programs. Objective: This study aimed to develop and evaluate a computerized adaptive testing version of the Knowledge of Effective Parenting Test-Internalizing module (KEPT-I CAT). Methods: Using computerized adaptive testing simulations from a large (n=1000) national dataset, we compared the performance of the KEPT-I CAT to both the full-length Knowledge of Effective Parenting Test-Internalizing module and a 10-item static short form (KEPT-I Brief). Results: Results indicated that the KEPT-I CAT achieved comparable efficiency to the KEPT-I Brief (10 items), while demonstrating superior psychometric properties and modestly reducing the potential for practice effects. Conclusions: Given these advantages, the KEPT-I CAT is well-suited for post-intervention assessment and may facilitate research examining how increases in parenting knowledge relate to changes in behavior and reductions in child internalizing symptoms.
