The clinical disorder most adjacent to maladaptive perfectionism is obsessive-compulsive personality disorder (OCPD). The name sounds a lot like OCD, but it’s a very different illness. OCPD can be marked by, among other diagnostic criteria, an excessive preoccupation with work at the expense of healthy interpersonal relationships, an obsession with control, and a preoccupation with orderliness and what the DSM refers to as, “rigid perfectionism.”[3]
