My research focuses on the measurement, analysis and interpretation of latent constructs (e.g. quality of life, well-being, fatigue, anxiety, depression) using self-reported outcomes and in particular Patient-Reported Outcomes (PRO). I am particularly interested in longitudinal PRO data and measurement invariance with a special focus on Response Shift and Differential Item Functioning using Rasch Measurement Theory and Structural Equation Modeling.
Critical examination of current response shift methods and proposal for advancing new methods.
