Patient-reported outcomes (PROs) are widely used to evaluate the impact of health technologies, practice innovations, or changes in health policy from the patients' perspective. This course is designed to familiarize people with the range of PRO domains and the role they can play in evaluating the effects of healthcare interventions. This includes symptoms (including those that arise as side-effects of treatment), functioning, general health perceptions, and health-related quality of life. The faculty will describe the steps that researchers generally go through in order to develop and test a new PRO measure. This will include qualitative concept elicitation work, item generation, cognitive interviewing, testing measurement models (when appropriate), and finally, assessment of validity and reliability. The course will also cover issues such as the role of the recall period and cultural/linguistic translation of measures. This is an entry level course which assumes only a passing familiarity with patient-reported outcomes.
