Purpose:
In 2021 a set of consensus-based and empirically informed reporting recommendations were developed for primary studies of the measurement properties of patient‑reported outcome measures (PROMs). With their use, we determined that certain reporting items were redundant, some required revisions, and additional items were needed. The aim of this study was to update the COSMIN reporting guideline and develop version 2.0 for studies on measurement properties of PROMs.
Methods:
There were seven phases to this update: 1. Identification of relevant experts for the meeting; 2. Solicitation of written feedback on the existing reporting recommendations checklist; 3. Development of the Explanation & Elaboration document; 4. A face-to-face consensus meeting; 5. Post-meeting revisions of the checklist and Explanation & Elaboration document; 6. Circulation of the resultant manuscripts to experts for solicitation of final feedback, and 7. Completion of the final documents and resultant manuscripts, distribution to all members for approval, and finalization.
Results:
Overall, the revised recommendations for version 2.0 consists of 31 general items and 37 specific items. Of the general items, 15 were revised or reordered and one item was added. Of the specific items, 15 were revised or reordered and two new items were added.
Conclusion:
We recommend that the earlier version of this guidance (version 1.0) no longer be used. These revised reporting recommendations (version 2.0) will help to guide those reporting or reading these investigations on the essential information that is recommended to be included.

The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care evaluation by...
