Primary Appointment

Associate Professor, Department of Symptom Research, Division of Internal Medicine, The University of Texas MD Anderson Cancer Center, Houston, TX

Bio Statement

I spend most of my time doing collaborative work that utilizes my quantitative background (psychometrics and statistics) and research training to develop and evaluate the measurement properties of patient-reported outcomes assessment tools and to help design and analyze studies with symptoms as primary outcomes.

More recently, I have been involved as an investigator in a consortium (with Memorial Sloan Kettering Cancer Center, Dana-Farber Cancer Institute, and Mayo Clinic) funded by the National Cancer Institute to develop and validate a patient-reported outcomes version of the Common Terminology Criteria Adverse Event (PRO-CTCAE). I co-led the development of the PRO-CTCAE items and I am currently involved in designing the validation study.

Research Interests

My primary research interest is in applying psychometrics to develop and evaluate symptom assessment tools. I was instrumental in the development of single-symptom (Brief Fatigue Inventory, BFI) and multiple-symptom (M. D. Anderson Symptom Inventory, MDASI) assessment tools. My collaboration with clinicians at M. D. Anderson have resulted in the development of several disease-specific and cancer-site-specific modules of the MDASI, including the MDASI-Brain Tumor, the MDASI-Head and Neck, the MDASI-Thyroid, the MDASI-Gastrointestinal Cancer, and the MDASI-Heart Failure, and others. I have provided our international collaborators with the necessary theoretic measurement framework to conduct foreign-language validation of our assessment tools.

An integral aspect of my research is the application of advanced statistical models in understanding symptom outcomes.  I am interested in determining how patient-reported outcome can be use to define and develop responder type analysis.
