Research Overview

Dr. Sideridis supports with his work on methods and statistics the Division of Developmental Medicine and the Department of Psychiatry at BCH. His research interests lie on (a) the determination of measurement invariance in instruments related to achievement and aptitude, and, (b) on evaluating the effects of systematic measurement error on individuals’ scores.

 

Research Background
