The diagnostic difference between OSDD and Dissociative Identity Disorder, and prevalence figures 

I received lots of questions about the category Other Specified Dissociative Disorders (OSDD) so have discussed in this video how this and DID are diagnosed, and what sets them apart from each other. Also included are published prevalence rates for these conditions, from Lowenstein (2018) Dissociation Debates: everything you know is wrong, Dialogues in Clinical Neuroscience, Vol 20 (3).
