A new educational tool for neuropsychological test raters in the dementia field: A Delphi study

Background Neuropsychological testing is the primary endpoint of clinical research in the field of dementia, making it essential for the rater to accurately calculate test data for an extensive assessment. However, many raters lack adequate skill to complete neuropsychological tests with sufficient confidence. Therefore, we developed and examined the utility of a checklist and a manual as tools for educating raters on their basic behaviours when conducting comprehensive neuropsychological evaluations in the field of dementia. Methods We conducted a seven‐step comprehensive study to develop rater training tools and examine their usefulness between April 2019 and February 2021 involving: 1. Development of a draft checklist, 2. Delphi review rounds, 3. Design of the final checklist, 4. Item weighting, 5. Examination of reliability, 6. Creating the manual, and 7. Examination of the usefulness of learning through rater educational tools (checklist and manual). Results The Delphi review round led to a highly reliable and valid checklist and manual. The total checklist score improved significantly (t = 2.37, P = 0.029) before and after manual learning. We found that the appropriate basic behaviours required by the rater to conduct neuropsychological testing skilfully within the dementia field could be acquired with this tool. Conclusions Using a robust development process, we integrated expert knowledge and experience, and developed a checklist and a manual for learning the basic behaviours of neuropsychological test raters in the field of dementia. Establishing standards of basic behaviour for neuropsychological raters will help promote dementia research and advances in medicine.
