Power and Sample Size Determination for the Group Comparison of Patient-Reported Outcomes with Rasch Family Models

BACKGROUND: Patient-reported outcomes (PRO) that comprise all self-reported measures by the patient are important as endpoint in clinical trials and epidemiological studies. Models from the Item Response Theory (IRT) are increasingly used to analyze these particular outcomes that bring into play a l...
