No paranoid peronality forum?

No paranoid personality forum and yet this disorder is in the DSM-5 and ICD-10...

Why is it subsumed under the avoidant personality forum? They're not even in the same DSM cluster.

Welcome to the forums. You may find a scattering of paranoia threads in the Living with Mental Illness, Social Phobias, Schizoid Personality and Delusional Personality forums.
I invite you to look around. Paranoia, per se, isn't always easy to classify without more information.
I'm using the following as my definition of Paranoia:
"Paranoia is the irrational and persistent feeling that people are 'out to get you'. The three main types of paranoia include paranoid personality disorder, delusional (formerly paranoid) disorder and paranoid schizophrenia".
Best of luck to you.

No, they're not in the same cluster, and I'm not sure why they were arranged that way, but they were. It's not something we can change at the moment. It's listed as a subforum of another as it's simply a much quieter forum- and it's lesser known than the six main PD forums, no less important though. We can't have every forum listed on the same level- the list of forums would go on forever.
