The test is crap. A) a series of questions is insufficient to diagnose a disorder of this type, and B) if you can complete the tests then, even if you are autistic, you're functioning at a sufficiently high level as to make a diagnosis of autism irrelavent. |
While I do agree that a simple online test will not definitively tell you if you have a form of autistic spectrum disorder, "real" diagnosis is done in a fairly subjective manner based on social interaction as well as other outward signs of ASD. There really is no lab test for autism. Also, we have to consider that "autism" today is a spectrum of disorders, ranging from those who are virtually unaffected to those with severe (classic) autism.
From the American Academy of Pediatrics:
| quote: | | The pediatrician is faced with the challenging task of suspecting an ASD diagnosis as early as possible and implementing a timely treatment plan to achieve the best outcome for the child and family. Early diagnosis of ASD is challenging in the context of primary care visits, because there is no pathognomonic sign or laboratory test to detect it. Thus, the physician must make the diagnosis on the basis of the presence or absence of a constellation of symptoms. ASD is a phenomenologic rather than an etiologic disorder (eg, trisomy 21 in Down syndrome), making the diagnosis more challenging. Pediatricians must rely on parent report, clinical judgment, and the ability to recognize criteria-based behaviors that define ASD. |
Here's the actual diagnostic criteria (autism) from DSM-IV:
| quote: | A. A total of six (or more) items from (1), (2), and (3), with at least two from (1), and one each from (2) and (3).
1. Qualitative impairment in social interaction, as manifested by at least two of the following:
a. marked impairment in the use of multiple nonverbal behaviours such as eye-to-eye gaze, facial expression, body postures, and gestures, to regulate social interaction.
b. failure to develop peer relationships appropriate to developmental level.
c. a lack of spontaneous seeking to share enjoyment, interests or achievments with other people eg: by a lack of showing, bringing or pointing out objects of interest.
d. lack of social or emotional reciprocity.
2. Qualitative impairments in communication as manifested by at least one of the following:
a. delay in, or total lack of, the development of spoken language not accompanied by an attempt to compensate through alternative modes of communication such as gesture or mime.
b. in individuals with adequate speech, marked impairment in the ability to initiate or sustain a conversation with others.
c. lack of varied, spontaneous, make-believe play or social imitative play appropriate to developmental level.
3. Restricted, repetitive and stereotyped patterns of behaviour, interests and activities, as manifested by at least one of the following:
a. encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus.
b. apparently inflexible adherence to specific nonfunctional routines or rituals.
c. stereotyped and repetitive motor mannerisms eg: hand or finger flapping or twisting, or complex whole-body movements.
d. persistent preoccupation with parts of objects.
B. Delays or abnormal functioning in at least one of the following areas, with onset prior to age 3 years:
1. social interaction
2. language as used in social communication
3. symbolic or imaginative play.
C. The disturbance is not better accounted for by Rett's Disorder or Childhood Disintegrative Disorder.

Asperger's is even more subjective (in my opinion);
| quote: | A. Qualitative impairment in social interaction, as manifested by at least two of the following:
1) marked impairment in the use of multiple nonverbal behaviours such as eye-to-eye gaze, facial expression, body postures, and gestures to regulate social interaction;
2) failure to develop peer relationships appropriate to developmental level;
3) a lack of spontaneous seeking to share enjoyment, interests or achievments with other people (eg: by a lack of showing, bringing, or pointing out objects of interest to other people);
4) lack of social or emotional reciprocity.
B. Restricted repetitive and stereotyped patterns of behaviour, interests, and activities, as manifested by at least one of the following:
1) encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus;
2) apparently inflexible adherence to specific, nonfunctional routines or rituals;
3) stereotyped and repetitive motor mannerisms (eg: hand or finger flapping or twisting, or complex whole-body movements);
4) persistent preoccupation with parts of objects
C. The disturbance causes clinically significant impairment in social, occupational, or other important areas of functioning.
D. There is no clinically significant general delay in language (eg: single words used by age 2 years, communicative phrases used by age 3 years).
E. There is no clinically significant delay in cognitive development or in the development of age-appropriate self-help skills, adaptive behaviour (other than social interaction), and curiosity about the environment in childhood.
F. Criteria are not met for another specific Pervasive Developmental Disorder, or Schizophrenia. |
I guess what I'm trying to say is that autism is a wide range of disorders that are diagnosed by outward function, not by any sort of invasive diagnostic procedure. In that regard, those with higher functioning autism (Asperger's, etc.) fall into the same diagnosing category as those with depression or ADHD. There is no routine lab test for depression or ADHD, and there isn't one for autism.
I don't mean to downplay ASD, as I have worked with individuals who were obviously impaired by it. However, and to put in bluntly, ASD is the new ADHD is the new depression. In my opinion it is grossly overdiagnosed due to a broadening of its definition, public attention, need to explain perceived abnormalities by medical means and cultural changes.
