摘要

Purpose The US Food and Drug Administration (FDA) 2009 guidance for industry on patient-reported outcome (PRO) measures describes how the Agency evaluates the psychometric properties of measures intended to support medical product labeling claims. An important psychometric property is test-retest reliability. The guidance lists intraclass correlation coefficients (ICCs) and the assessment time period as key considerations for test-retest reliability evaluations. However, the guidance does not provide recommendations regarding ICC computation, nor is there consensus within the measurement literature regarding the most appropriate ICC formula for test-retest reliability assessment. This absence of consensus emerged as an issue within Critical Path Institute's PRO Consortium. The purpose of this project was to generate thoughtful and informed recommendations regarding the most appropriate ICC formula for assessing a PRO measure's test-retest reliability.
