I’m looking for a good clinical definition of someone who has 1001 rules that s/he is convinced must be followed. A DSM-like diagnosis would be great. I have come across people with this trait and quite often their family history is one where a parent (or the person her/himself) were career government workers (e.g., military, post office, public education). My best descriptions that I could come up with were ‘bureaucratic’, ‘dogmatic’, ‘perfectionistic’, ‘rigid’. A DSM-like diagnosis that comes to mind would be OCD but that doesn’t seem quite right (or maybe I’m wrong here). I was hoping to find something more concise and complete.
