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

## TL;DR

This study developed a computerized adaptive test to efficiently assess parenting knowledge, showing it performs as well as a shorter version but with better accuracy.

## Contribution

The novel contribution is the creation and validation of a computerized adaptive test version of the KEPT-I.

## Key findings

- The KEPT-I CAT performed as efficiently as the KEPT-I Brief with 10 items.
- The KEPT-I CAT showed better psychometric properties than the KEPT-I Brief.
- The KEPT-I CAT reduces potential practice effects modestly.

## Abstract

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.

This study aimed to develop and evaluate a computerized adaptive testing version of the Knowledge of Effective Parenting Test–Internalizing module (KEPT-I CAT).

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 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.

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.
