COMET

Chicago Objective Measurement Table

The meeting held on February 21, 2002 at the American Society for Clinical Pathologists was attended by Nikolaus Bezruczko, Patrick Fisher, Tom O'Neill, Joan Stelmack, Matthew Enos, Johnna Gveorgvieva, Lidia Dobriam, Chris Condon, Gaston Mbateng, Mary Lunz and Donna Tatum, representing Hines VA Hospital, University of Illinois, Rehabilitation Institute of Chicago, American Society for Clinical Pathologists, National Council for State Boards of Nursing, Johnson O'Connor Research Foundation, Inc, Measurement Research Associates, Inc, and Measurement & Evaluation Consulting.

Measurement discussion focused on Donna Tatum's presentation "Analyzing Longitudinal Data: Problems and Solutions" which scale definition and invariance issues including, methods of establishing step invariance, and item migration in longitudinal constructs. She outlined a procedure, and compared it with an alternative by Wolfe & Chiu. A underlying issue concerns measurement integrity which dictates that changes in item order not be represented in scale structure. Constructs can change, but units must remain constant.

COMET is open to researchers, faculty, and students committed to advancing objective measurement methods. For information contact Nikolaus Bezruczko
