The ASD assessment process is pretty detailed and having gone through it with our daughter this year we found it’s not that easy to get a diagnosis. I don’t know if this is helpful OP but this from the final report we received (DD didn’t meet enough of the criteria to get a diagnosis):
When diagnosing an Autism Spectrum Disorder, there are clear criteria (outlined by the DSM) that must be met for a diagnosis to be given. The criteria are as follows:
A. Persistent deficits in social interaction and communication across multiple contexts.
B. Evidence of rigid, restrictive and repetitive interests and behaviours.
C. Symptoms must be present in the early developmental period (though may not fully
manifest until social demands exceed limited capacities).
D. Symptoms cause clinically significant impairments in social, occupational, or other
important areas of functioning.
E. The difficulties are not better explained by an intellectual disability.
Cluster A: Social Communication and
Interaction Deficits
Evidence must be present for all 3 areas:
- Evidence of deficits in social-emotional
reciprocity:
- Absence of typical back-and-forth
conversation
- Reduced sharing of interests (unless
directly prompted)
- Absence of intent to initiate or
respond to social interactions.
2.Evidence of deficits in non-verbal
communicative behaviours used for social interaction
—Deficits in non verbal communicative behaviours used for social interaction e.g. descriptive or
instrumental gestures
- Restricted integration of verbal and
non-verbal communication
- Absence of understanding into the use of gestures
3.Evidence of deficits in developing,
maintaining and understanding
relationships:
- Difficulties in adjusting behaviours
to suit various social contexts
- Difficulties in sharing imaginative play
Cluster B: Restrictive and Repetitive
Patterns of Behaviour, Interests or Acitivies
Evidence must be present for at least 2 of
the following:
- Stereotyped or repetitive motor
movements, use of objects or speech
- Insistence on sameness, inflexible
adherence to routines, or ritualised
patterns of behaviour
- Highly restricted, fixated interests that
are abnormal in intensity or focus
- Hyper or hypo-reactivity to sensory
input or unusual interests in sensory
aspects of the environment e.g.
indifference to pain/temperature, adverse
response to sounds or textures, visual
fascination with lights or movement
