Abstract

The Knowledge of Evidence-Based Services Questionnaire (KEBSQ) is an objective measure of therapist knowledge of practices derived from the evidence base for the treatment of youth psychopathology. However, the length of this measure (i.e., 40 items) and respondent demands associated with each item makes it burdensome for researchers and clinicians. This study developed and validated a Short Form of the KEBSQ using Item Response Theory measurement models. The Short Form consists of 17 items and generates two separate scores: Correct Endorsements and Correct Rejections. The Short Form was found to correlate highly with and perform similarly to the Full Form, providing preliminary validity evidence.

Keywords: Evidence-based practices; Item response theory; Knowledge.
