We do not calculate an unofficial impact factor for JMIR Res Protoc because this would demonstrate a regrettable misuse of the impact factor (see What is impact factor misuse?). The impact factor is a journal-based average of citations, and should not be misused to deduce the importance or significance of the research, in particular if it is only proposed research!
Our authors do not (or should not) publish in JMIR Res Protoc (JRP) to get "impact factor brownie points".
Proposals and protocols are published to enhance transparency, collaboration, and to establish priority by creating an early record of their research plan and activities (see Why should I publish my protocol or grant proposal?).
The "impact" of a protocol is measurable not so much with citations, but in terms of immediate benefit to the society (reduction of duplication of work), new collaborations and successful grant proposals resulting from publication of a protocol, and/or easier publication of the subsequent paper that reports the results in high-impact factor journals (some of which now require the publication of a protocol). In addition, JRP authors can publish their full study results in any JMIR journal (which are all high-impact, well cited journals) with a 20% discount, and the paper is in principle accepted because it is treated as "registered report" (see Why should I publish my protocol or grant proposal?).
For further questions about the impact factor, please contact its' producer, Clarivate. Sadly, as publisher we have limited influence on which journals Clarivate decides to cover. We invite you to fill in their form, as perhaps this will encourage them to speed up their evaluation.
