Development, validation and interpretation of the PROMIS Itch Questionnaire: a patient-reported outcome measure for the quality of life impact of itch

Current patient-reported outcome measures for itch are limited and may not capture its full impact on health-related quality of life (HRQOL). We sought to develop, calibrate and validate banks of questions assessing the HRQOL impact of itch as part of Patient-Reported Outcomes Measurement Information System ® (PROMIS®). A systematic process of literature review, content-expert review, qualitative research, testing in a sample of 600 adults, classical test theory methods, and item response theory (IRT) analyses were applied.
