Case Specificity Is Essential for Valid Performance Assessment of Physicians.
Bashook, Philip G.
Assessment of clinical performance is intended to make generalizations about a physicians competence. Performance assessments involve three interacting components: the candidate, the cases, and the raters. Confidence in generalizations depends on reliability of the measurements and whether the cases represent the competence domains of interest. Since clinical tasks and decisions are not general traits, but integral to specific patient cases, how many and what cases are sufficient to overcome case specificity. This paper offers a solution by adapting work by A. LaDuca to define an assessment blueprint and select representative cases that sample accurately the competence domain core and defined border (construct validity). Other concerns are measurement precision and score reproducibility (reliability) that are influenced by the quantity of cases and the way measurements are taken. Improved reliability requires controlling for variability across cases, raters, and exam administration using structural (e.g., balanced case selection, rater training) and statistical controls.
