To make a rough assessment of whether a person has Autistic Disorder or not, tick the box under "ANS" if your client matches the description.

Note: If you are diagnosing an adult client, it is best to use his behavior as a young child for this test. He may learnt to cope through experience and may not fulfill the diagnostic criteria any more.

Criteria ANS
IA. The client has obvious and consistent problems with social interactions, as described by at least 2 of the following:

A

Does not use body language when interacting (e.g. no eye contact, no change of facial expression, maintains a rigid body posture)

B

Does not interact with people of the same age or group (e.g. a student makes friends with his teachers but not his classmates)

C

Lack of spontaneous emotional expression and sharing with others (e.g. does not point at objects; does not play with, touch, and chit-chat with others by his own initiative)

D Lack of social or emotional playing (e.g. preferring to be alone, not participating in social games, or reluctantly involving others only as tools or "mechanical" aids)

IB. The client has obvious and consistent problems with communications, as described by at least 1 of the following:

A

He develops speaking very slowly compared to his peers or has no speech at all (i.e. Does not even communicate with gestures)

B

Even if he can speak, he still cannot have meaningful or useful conversations with others

C

He keeps on using peculiar terms or speaking in an very odd way (e.g. using self-invented words, consistently making the same grammar mistakes, speaking in a peculiar accent)

D

He does not play "make-believe" games or copy other children who are playing


IC. The client keeps repeating certain limited activities or pursuing certain specialized interests, described by at least 2 of the following:

A

Constant and persistent behavior that cannot be explained (e.g. keeps counting coins, watching bottle cap move, or watching the same video clip again and again)

B

Insistence on following specific, useless routines and rituals (e.g. must eat the same food prepared the same way in the same way; must always go to school on the same time along the same route doing the same things)

C

Keeps making the same useless movement without reason (e.g. hand or finger flapping or twisting, or complex whole-body movements)

D Obsession with certain parts of objects (e.g. keeps playing with wheels of a toy truck or a toy plane's propeller rather than the entire toy)

II. The client has already exhibited the above syndromes before age 3

III. The client does not have Rett's Disorder or Childhood Disintegrative Disorder

probably NOT autistic
