This Note presents a methodology for evaluating Likert-type scales. Multitrait scaling is a straightforward approach to scale analysis that focuses on items as the unit of analysis and utilizes the logic of convergent and discriminant validity. Multitrait scaling is illustrated with the Multitrait Analysis Program using patient satisfaction data from the Medical Outcomes Study.
