The most significant criteria that POCD fails is the last one, which is necessary for a diagnosis of OCD:
You're still not grasping that intrusive sexual thoughts (which disgust the person experiencing them rather than arousing them) are
not sexual fantasies. Just like someone having flashbacks about being raped is not having a sexual fantasy. Intrusive thoughts are not "fantasies." Do you think someone with OCD obsessively washing their hands because they think they'll get MRSA from touching a hand towel is "fantasizing" about getting MRSA?
That's just a journal article, is it not part of accepted diagnostic criteria nor guidelines. Further, it is not listed anywhere in the section of the DSM-5-TR under OCD.
And yet the APA allows psychiatrists to post diagnostics of it all over their own PsycNet site. Don't they realize that someone online just scientifically proved it didn't exist after skimming a description of OCD for ten seconds? You better write to them, quick!
