Abstract
Abstract: Clinical judgment among new-to-practice nurses is critical for safe patient care. The Lasater Clinical Judgment Rubric (LCJR) is a known instrument in undergraduate nursing education research. This study evaluated the internal consistency reliability and changes in the LCJR in a sample of 17 new-to-practice nurses in a simulated setting across four measurements. Cronbach's alpha reliability for the LCJR was .90. Effect sizes ([eta]2) ranged from .01 to .45, with only the reflecting subscale demonstrating an effect. Study team and study participants' self-ratings on the LCJR were compared; team members' ratings were significantly lower than participants' self-ratings.
