The four separate disorders under DSM-IV have been merged into Autism Spectrum Disorder (ASD) under DSM-5. Most of those diagnosed under DSM-IV should also be able to meet the criteria for ASD in DSM-5.

The table below provides a simplified version of the DSM-5 definition, used by professionals to diagnose disorders.

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

Criteria ANS
A. The client has problems communicating and interacting no matter the location or the people involved. The 3 problems below must exist:


The client is not interested to talk with another person. When he talks, he shares little of his feelings and reactions, focusing instead on impersonal facts and opinions. His partner must take the effort to keep the conversation going.


The client has unusual body language and does not make eye contact. He may not even show any emotional reactions on his face or gesture with his hands. He does not react to non-verbal cues such as boredom or anger expressed by the person he is speaking to.


The client could not make friends. He could not join the imaginative play of other children his age. He has no interest in knowing what other people are doing or saying.

B. The client keeps repeating specific behaviors and/or specialized interests, described by at least 2 of the following:


The client keeps repeating certain phrases and actions.


The client keeps insisting on performing certain rituals, playing in the same way and eating the same food. He is unable to tolerate even small changes to his routines.


The client has obsessions with certain objects and interests that are much stronger than a typical interest or liking.


The client has an exaggerated reaction to certain sounds, textures or touch. However, he may not react at all to loud noise and environmental heat/cold.

C. The above symptoms must be present in early childhood.

D. These symptoms prevent the client from doing the basic activities that he is expected to be able to do.

DSM-5 definition on Autism Spectrum Disorder

Must meet criteria A, B, C, and D:

A) Persistent deficits in social communication and social interaction across contexts, not accounted for by general developmental delays, and manifested by all of the following:

  • Deficits in social-emotional reciprocity; ranging from abnormal social approach and failure of normal back and forth conversation through reduced sharing of interests, emotions, and affect and response to total lack of initiation of social interaction.
  • Deficits in nonverbal communicative behaviors used for social interaction; ranging from poorly integrated- verbal and nonverbal communication, through abnormalities in eye contact and body language, or deficits in understanding and use of nonverbal communication, to total lack of facial expression or gestures.
  • Deficits in developing and maintaining relationships, appropriate to developmental level (beyond those with caregivers); ranging from difficulties adjusting behavior to suit different social contexts through difficulties in sharing imaginative play and in making friends to an apparent absence of interest in people

B) Restricted, repetitive patterns of behavior, interests, or activities as manifested by at least two of the following:

  • Stereotyped or repetitive speech, motor movements, or use of objects; (such as simple motor stereotypes, echolalia, repetitive use of objects, or idiosyncratic phrases). 
  • Excessive adherence to routines, ritualized patterns of verbal or nonverbal behavior, or excessive resistance to change; (such as motor rituals, insistence on same route or food, repetitive questioning or extreme distress at small changes).
  • Highly restricted, fixated interests that are abnormal in intensity or focus; (such as strong attachment to or preoccupation with unusual objects, excessively circumscribed or perseverant interests).
  • Hyper-or hypo-reactivity to sensory input or unusual interest in sensory aspects of environment; (such as apparent indifference to pain/heat/cold, adverse response to specific sounds or textures, excessive smelling or touching of objects, fascination with lights or spinning objects).

C) Symptoms must be present in early childhood (but may not become fully manifest until social demands exceed limited capacities)

D) Symptoms together limit and impair everyday functioning.



Social Communication

Restricted Interests & repetitive behaviors

Level 1

‘Requiring support’

Without supports in place, deficits in social communication cause noticeable impairments.  Has difficulty initiating social interactions and demonstrates clear examples of atypical or unsuccessful responses to social overtures of others.  May appear to have decreased interest in social interactions. 

Rituals and repetitive behaviors (RRB’s) cause significant interference with functioning in one or more contexts.  Resists attempts by others to interrupt RRB’s or to be redirected from fixated interest.

Level 2 

‘Requiring substantial support’

Marked deficits in verbal and nonverbal social communication skills; social impairments apparent even with supports in place; limited initiation of social interactions and reduced or abnormal response to social overtures from others.

RRBs and/or preoccupations or fixated interests appear frequently enough to be obvious to the casual observer and interfere with functioning in a variety of contexts.  Distress or frustration is apparent when RRB’s are interrupted; difficult to redirect from fixated interest.

Level 3 

‘Requiring very substantial support’

Severe deficits in verbal and nonverbal social communication skills cause severe impairments in functioning; very limited initiation of social interactions and minimal response to social overtures from others.  

Preoccupations, fixated rituals and/or repetitive behaviors markedly interfere with functioning in all spheres.  Marked distress when rituals or routines are interrupted; very difficult to redirect from fixated interest or returns to it quickly.
