Fritz Drasgow is a Professor of Psychology at the University of Illinois at Urbana-Champaign. His research focuses on psychological measurement, computerized testing, and the antecedents and outcomes of sexual harassment. His recent work focuses on psychometric theory for personality assessment. Drasgow is exploring the use of ideal point models in which the probability of a positive response is greatest when the item closely describes the person and decreases when the item reflects a trait level that is either lower or higher than the individual's trait level.
