Abstract
Background: Situational judgment tests (SJTs) are used in health sciences education to measure knowledge using case-based scenarios. Despite their popularity, there is a significant gap in the validity evidence and research on the response process that demonstrate how SJTs measure their intended constructs. Models of the SJT response process have been proposed in the literature; however, few studies explore and expand these models beyond surface-level attributes. The purpose of this study was to describe the factors and strategies involved in the cognitive process examinees use as they respond to SJT items.Methods: Thirty participants—15 students and 15 experienced practitioners—completed a 12-item SJT designed to measure empathy. Each participant engaged in a think-aloud interview while completing the SJT followed by a cognitive interview probing their decision-making processes. Interviews were transcribed and independently coded by three researchers to identify salient themes and factors that contributed to the response process. Results: Results suggested that the SJT response process included the complex integration of comprehension, retrieval, judgment, and response selections. Each of these response process stages were influenced by attributes such as perceived objective of the task, job-specific knowledge, assumptions about the scenario, and item setting. Conclusions: This study provides an evaluation of the SJT response process and contributes exploratory information to the validity evidence of SJTs; these findings can inform the design, interpretation, and utility of SJTs.
