Science
PROMIS integrates the fields of Psychometrics, Survey Research, Health Information
Technology, Clinical Research, and Qualitative Research. PROMIS builds and validates
instruments that measure feelings, functions, and perceptions applicable to a range
of chronic conditions, enabling efficient and interpretable clinical research and
clinical practice application of patient–reported outcomes.
PROMIS utilizes rigorous methodology for developing its measures and testing their
validity. The development of items for each domain’s item bank consisted of six
phases: identification of items, item classification and selection, item review
and revision, focus group input on domain coverage, cognitive interviews with individual
items, and final revision before field testing.
