- Patient Reported Outcome (PRO) - A measurement that comes directly from the patient
- Clinician Reported Outcome (ClinRO) - An assessment performed by a trained medical professional
- Observer Reported Outcome (ObsRO) - An assessment performed by an observer (i.e., a non-clinician, such as a teacher or caregiver)
- Performance Rated Outcome (PerfO) - A measurement based on a task(s) performed by a patient
