Me. Lunz et Cw. Deville, VALIDITY OF ITEM SELECTION - A COMPARISON OF AUTOMATED COMPUTERIZED ADAPTIVE AND MANUAL PAPER AND PENCIL EXAMINATIONS, Teaching and learning in medicine, 8(3), 1996, pp. 152-157
Background: As computerized adaptive testing (CAT) becomes more preval
ent, it is important to confirm that the computerized adaptive and pap
er-and-pencil (P&P) examinations offer comparable validity and statist
ical performance. Purpose: The purpose of this study was to investigat
e the validity and statistical properties of automated item selection
(CAT) compared to manual item selection (P&P). Methods: A committee of
specialists rated computerized adaptive tests (CATs) and P&P examinat
ions with regard to face validity, adherence to test specifications, o
rdering of items, and cognitive skill distribution. The psychometric p
roperties were compared. Results: Results indicated that the CATs and
P&P examinations were comparable for face, content, and construct vali
dity, as well as psychometric characteristics. Conclusions: Test const
ructed automatically by the computer or manually for P&P can meet the
criteria for validity and statistical performance. These findings gene
ralize to any carefully developed examination program.
