There isn't a clearly identified cause for "obsessive-compulsive personality disorder". One of the things that this has been linked to, at least in the psychoanalytic literature, is the "anal character". Since these people tend to be very controlling, or feel a great need to try to control things, there has been some suggestion that it is linked to cooperationg with the mother during potty training. This theory obviously relates back to the "anal character" found in pschoanalysis.
