Submitter here. I ended up at that journal by following a link in this opinion blog at The New York Times: http://op-talk.blogs.nytimes.com/2014/11/26/what-if-were-wro... The author, Anna North, thinks it's legit. Also, it's linked to here by the NIH: http://www.ncbi.nlm.nih.gov/pmc/journals/1820/

"Biol. Mood Anxiety Disord." is probably the ISO 4[1] abbreviation of the journal, hence the domain.

> For instance, when citing a paper from the European Physical Journal, the ISO 4 standard prescribes the abbreviation "Eur. Phys. J.". Note that ISO 4 is particularly efficient for abbreviating journal titles, as the word journal for example is abbreviated to simply "J.".
