3 - None of the exclusion criteria must be observed

The following symptoms must be permanent :

(A) Mannerism according to WKL, ie rigid behavioral rituals either positive (compulsive aspect) or negative (omission = loss of behavioral register). 3 of the 4 criteria must be present if no processual symptoms, 2 are sufficient if processual symptoms present:

- No egodystonic feeling, symptoms accepted as normal (no insight) even if patients recognize them as meaningless

- No attempt to fight against the compulsions (no conflict)
