More information

Dr. Magnus grew up in a small town in southeastern Massachusetts. She completed her undergraduate degree at Mount Holyoke College in western Massachusetts, where she become interested in the intersection of psychology, statistics, and quantitative research methodology. She went on to earn her PhD in Quantitative Psychology with a minor in Biostatistics from the University of North Carolina at Chapel Hill, specializing in psychometrics, item response theory, and the assessment of health outcomes. In addition to conducting her own methodological work, Dr. Magnus enjoys collaborating with behavioral and health scientists who use tests and questionnaires as part of their research. She is also enthusiastic about instilling an appreciation of statistics in her students, and she encourages anyone interested in learning more about quantitative psychology to e-mail her.

Dr. Magnus encourages anyone with a strong statistical background who is interested in the Clinical Psychology PhD program to contact her. She is particularly eager to work with graduate students who have an interest in psychometrics and the analysis of questionnaire data.



Education

Teaching Interests

At the undergraduate level, Dr. Magnus teaches Psychological Measurements & Statistics. At the graduate level, Dr. Magnus teaches Advanced Statistics & Design I & II. In future semesters, she plans to teach courses in Psychological Testing and Latent Variable Modeling.

Research Interests

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.
