Advising on Preferred Reporting Items for Patient-Reported Outcome Instrument Development： the PRIPROID

Objective： The reporting of patient-reported outcomes （PRO） instrument development is vital for both researchers and clinicians to determine its validity, thus, we propose the Preferred Reporting Items for PRO Instrument Development （PRIPROID） to improve the quality of reports. Methods： Abiding by the guidance published by the Enhancing the QUAlity and Transparency Of health Research （EQUATOR） Network, we had performed 6 steps for items development： identified the need for a guideline, performed a literature review, obtained funding for the guideline initiative, identified participants, conducted a Delphi exercise and generated a list of PRIPROID items for consideration at the face-to-face meeting. Results： Twenty three items subheadings under 7 topics were included： title and structured abstract, rationale, objectives, intention, eligibility criteria, conceptual framework, items generation, response options, scoring, times, administrative modes,burden assessment, properties assessment, statistical methods, participants, main results, and additional analysis, summary of evidence, limitations, clinical attentions, and conclusions, item pools or final form, and funding. Conclusions： The PRIPROID contains many elements of the PRO research, and this assists researchers to report their results more accurately and to a certain degree use this instrument to evaluate the quality of the research methods.
