Mapping the content of the Patient-Reported Outcomes Measurement Information System (PROMIS®) using the International...

Area of Science:

• Health Outcomes Measurement
• Rehabilitation Science
• Health Informatics

Background:

• The Patient-Reported Outcomes Measurement Information System (PROMIS) is a US National Institutes of Health initiative.
• PROMIS has developed self-reported item banks for physical, mental, and social health.

Purpose of the Study:

• To describe the content of PROMIS at the item level.
• To map PROMIS items to the World Health Organization's International Classification of Functioning, Disability and Health (ICF) framework.

Main Methods:

• All publicly available PROMIS adult items (as of 2012) were systematically assigned to relevant ICF concepts.
• The content of PROMIS adult item banks was analyzed using mapped ICF code descriptors.

Main Results:

• All 1,006 PROMIS items mapped to ICF concepts, primarily at the second level of classification.
• PROMIS item banks cover most major concepts within ICF's body functions (b) and activity and participation (d) components.
• Coverage is minimal for ICF's body structures (s), some body functions (b), and environmental factors.

Conclusions:

• The mapping of PROMIS items to the ICF provides a valuable resource for users.
• This facilitates the evaluation of ICF-related content within specific PROMIS instruments.
• It supports the selection of appropriate PROMIS instruments for ICF-based health outcome measurement applications.
