The Journal of Medical Internet Research (JMIR) has been the pioneering digital health journal, publishing seminal papers on information and communication technologies in health and health care for 20 years now.
JMIR sister or specialty journals (Which journal titles is JMIR Publications currently publishing?) - even though they have "JMIR" in the title - are distinct journals, with distinct editorial boards and sometimes slightly different editorial policies, catering to specific audiences, specialties, or focusing on a specific stage in the research cycle (protocols/proposals, formative research) or on specific technologies. All JMIR journals have a shared peer-reviewer database which makes sure that reviewers are used efficiently and not overburdened with too many peer-review requests from different journals. All JMIR journals also share the same high standards and production values.
Although they are newer (and therefore not all "Impact-Factor ranked"), sister/specialty journals are not deemed "inferior" to the original JMIR (and using the impact factor as metric constitutes misuse, see What is impact factor misuse?).
Also, please note that "JMIR" in the journal title refers to the brand (the name of the publisher). While all JMIR journals have a unique emphasis on technology in health and aspire to be leaders in their fields, the "I" in the title of a journal like JMIR Public Health and Surveillance or JMIR Mental Health does not necessarily stand for "Internet". See What does "JMIR" in the title of your journals stand for? Once again: JMIR is the name/brand of the publisher ("JMIR Publications"). When citing a journal, please do not expand the title -- e.g. "Journal of Medical Internet Research Mental Health" is not the title of the journal!
This is akin to how other publishers position and brand their journal portfolio. For example, the BMJ Publishing Group may publish the BMJ (formerly "British Medical Journal"), but also a portfolio of journals such as BMJ Paediatrics or BMJ Gastroenterology, which are independent. Similarly, there is JAMA, with JAMA Dermatology, JAMA Internal Medicine etc. as "sister" journals. Another example is the "BMC" journals series by Springer/BiomedCentral.
Just like at other publishers, JMIR Publications uses a system of cascading peer-review (portable peer-reviews), where authors can have a submission automatically considered for another journal without going through the peer-review process again, if a submission is deemed out of scope or not interesting enough for a specific journal. This is an increasingly common practice also at other publishers.
Finally, JMIR Publications also publishes journals without "JMIR" in the title. These are community journals founded or owned by other parties such as medical societies, and published by JMIR Publications. For example, the Journal of Participatory Medicine is the journal of the Society for Participatory Medicine, published by JMIR Publications.
