Abstract
Questions persist regarding the evaluation of cognitive processes related to clinical reasoning when resolving situations in a learning by concordance tool. This Delphi technique study aimed to validate a clinical reasoning assessment rubric based on script theory. Seventeen experts participated in the study. Two rounds of consultation were conducted to obtain a consensus on the accuracy and clarity of the rubric descriptors (clarity index and content validity index ≥ 0.9). The results inform future research procedures and the intended use of the rubric to facilitate evaluator inferences, provide student feedback, and support the development of learners' clinical reasoning.
