PMID 31869848WHAT IT FOUND
CoreLex checklists for aphasia story and picture tasks are now gathered in one place.
They can help SLPs track which common words a patient produces, but each checklist was built differently, so choose one that matches the task and patient.
Key findings
01CoreLex checklists have been scattered across papers and conference proceedings, so this article collects them with development and norm information.
02People with aphasia produced fewer CoreLex items than healthy controls across discourse tasks, and subtype and fluency differences were reported.
03Checklists differ in design, so they should be used for the purposes they were developed for.

What it does not show
The checklists come from different studies with different samples, tasks, word types, and purposes, so they are not interchangeable. Some checklists have no normative data, and some were developed from healthy controls only or from small aphasia samples. The Cinderella sample included relatively more people with mild aphasia and fewer with more severe aphasia, so its differences may not represent severe aphasia. The article is a compendium and description of prior work, not a trial of whether CoreLex improves diagnosis or treatment outcomes. Different development choices affect interpretation, such as using one checklist across ages versus separate age-bin and word-type checklists.
Declared interests
The supplied text does not include a funding or conflict-of-interest declaration; the publication type lists research support from a non-U.S. government source.
The easy way to misread this
Do not read CoreLex checklists as proof that a communication treatment works. They score which common words a person produces in discourse, and the supplied text reports group differences and correlations, not tested treatment effects.
