Dr. Magnus’ research concentrates on the development of statistical methods for the analysis of item response data from tests, surveys, and questionnaires. Such data commonly arise from psychological and educational testing and measurement, as well as the assessment of health outcomes. As part of this research, she also investigates ways in which biostatistical methodology can be used in the adaptation of measurement models to behavioral and health outcomes research. Dr. Magnus’ secondary research interests are centered on the evaluation and use of tests and questionnaires in practice, mainly through collaborative work across psychology, public health, and medicine.
