One barrier to interpreting individual studies on the measurement properties (MPs) of PROMs is the frequent underreporting of important information. Although a checklist for investigating the methodological quality of studies on MPs of health status measurement instruments has been developed, guidelines for reporting these studies in the peer-revieWed literature do not exist. Objective: To develop a set of consensus and empirically based reporting recommendations for primary studies of the MPs of PROMs. Methods: This study included 4 phases: (1) conducting an extensive literature revieW of methods for performing or reporting studies testing MPs of PROMs; (2) preparing for a Delphi process to develop a consensus about reporting requirements by identifying experts to participate; (3) conducting the Delphi rounds of voting on the item lists developed in phase 1; and (4) developing recommendation and guidance documents. Results: The literature revieW resulted in our including 92 reporting items in the Delphi survey. A total of 83 individuals (from 12 countries) agreed to participate in the Delphi survey, With 47, 30, and 25 responding in rounds 1, 2, and 3, respectively. After 3 rounds, We achieved consensus on a set of 71 items separated into a set of 35 “common” items (relevant to all studies on MPs) and 36 “specific” items (exclusively relevant to 1 of the 9 MPs: (1) reliability, (2) measurement error, (3) internal consistency, (4) content validity, (5) face validity, (6) construct validity [including structural validity, hypothesis testing, and cross-cultural validity], (7) criterion validity, (8) responsiveness, and (9) interpretability). We created a manuscript for publication of the protocol, a PCORI final report, and similar to the final report, but much shorter, a manuscript also meant for publication of this Work. Conclusions: Consensus Was achieved on 2 nonduplicative sets of items, 71 in total, for inclusion in a reporting guideline for studies on MPs of PROMs. These items Will guide researchers on the necessary information
