Most individuals who take, interpret, design, or score tests are aware that examinees do not always provide full effort when responding to items. However, many such individuals are not aware of how pervasive the issue is, what its consequences are, and how to address it. In this digital ITEMS module, Dr. James Soland will help fill these gaps in the knowledge base. Specifically, the module enumerates how frequently behaviors associated with low effort occur, and some of the ways they can distort inferences based on test scores. Then, the module explains some of the most common approaches for identifying low effort, and correcting for it when examining test scores. Brief discussion is also given to how these methods align with, and diverge from, those used to deal with low respondent effort in self-report contexts. Data and code are also provided such that readers can better implement some of the desired methods in their own work.
