ARS domains	Items (N)	Description
Hypo-Attunement	3	The immediate feeling of reduced attunement, i.e., emotional contact with other persons. The pervasive feeling of inexplicability /incomprehensibility of people's behavior and social situations.
Invasiveness	3	Feeling oppressed and invaded by the others, from without.
Emotional flooding	2	Feeling oppressed and submerged from within by paroxysms of one's emotions and bodily sensations evoked by interpersonal contacts.
Algorithmic conception of sociality	3	The conceptual, analytic, hyper-cognitive, hyper-rationalist, hyper-reflective stance toward sociality. Patients may endorse a mechanistic, strategic and in some way “mathematisable” (as in a chess game) conceptualization of interpersonal transactions in everyday life.
Antithetical attitude toward sociality	3	Feeling to be vulnerable to the influx coming from the external world and claim one's independence as the most important value.
Idionomia	2	Idionomia is characterized by an existential re-orientation driven by the exaltation of one's own principles, interrogations, or world-view. This exalted existential standpoint does not allow integration or compromise with the other's point of view or with common sense.
