The article below may contain offensive and/or incorrect content.

We report on the development and psychometric properties of an instrument for the assessment of knowledge of effective parenting skills specific to conduct problems using an item response theory (IRT) framework. The initial item pool (36 items) for the Knowledge of Effective Parenting Test (KEPT) was administered online to a national sample (N = 1,570) selected to match the U.S. population on key demographic variables. Items with strong psychometric properties and without significant differential item functioning (DIF) by race/ethnicity were retained, resulting in a 21-item version of the KEPT with excellent reliability and validity. We also created a brief 10-item version of the KEPT to reduce respondent burden and to enhance its utility for repeated measurement in longitudinal and intervention research. We report norms and percentiles for both the 21-item version (KEPTâ€"Full) and the 10-item version (KEPTâ€"Brief). (PsycINFO Database Record (c) 2019 APA, all rights reserved)
