Michigan Retinal Degeneration Questionnaire
TECHNOLOGY NUMBER: 2021-065
OVERVIEW
Validated Patient Reported Outcomes (PRO) measure- Focused on conditions of inherited retinal degeneration (IRDs)
- Evaluates visual function
BACKGROUND
The Michigan Retinal Degeneration Questionnaire (MRDQ) is a validated patient reported outcomes measure designed in accordance with U.S. FDA guidelines, specifically for conditions of inherited retinal degeneration (IRDs) that can be applied to therapeutic clinical trials.
The MRDQ contains 59 questions and is designed to be interviewer-administered in around 20-30 minutes and evaluates visual function across seven physiologically relevant visual function domains:
- Central
- Color
- Scotopic
- Mesopic
- Photopic
- Photosensitivity
The psychometrically validated patient-reported outcomes measure was reduced to a 59-item questionnaire measuring 7 unidimensional domains. A total of 39 items were removed due to poor factor loading, low item-information, poor person-ability differentiation, or high item-level interdependence. This novel questionnaire produces reliable domain scores for person-ability that exhibit low test-retest variability across repeated administration.
The final PRO questionnaire, known as the Michigan Retinal Degeneration Questionnaire (MRDQ) is psychometrically validated and available for use in therapeutic evaluation for patients with IRDs. Each domain is scored using an independent person-disability measure. Instructions on administering and scoring the MRDQ are included with license.
