But 95% of research currently published on autism is irrelevant to my son (and others like him) because it's on high functioning autism.
When you are dealing with the severe autism group- those who remain severely autistic into adulthood which is the group I'm interested in (and incidentally the group many of those who appear to have been vaccine damaged find themselves in)- the effect of ABA on young children who are more able than them is completely irrelevant.
For this group you need a highly individual approach - in my son's school there are some children for example who need intensive interaction rather than ABA. At his respite centre an understanding of each individual's trigger points are required and different responses to challenging behaviours are needed. You can't develop a 'this strategy will work with a child with severe autism' because that's not the nature of the condition. This may reflect why most of the research on severe autism takes the form of case studies.
My research looks partly at children taking part different therapies within different settings. It's interesting to see the same child taking part in different therapies and to see the different responses. IMO much of research focuses too much on the person with autism rather than the setting they are in and the people around them - this can make a huge difference when you have a severe communication disorder.
People with autism at the end of the day are just people - and lots of very different people - they're not one homogenous group. Ultimately families will choose therapies that work for them and their situation rather than ones that have been shown statistically to work for groups of children who are nothing like their child. I don't care how many studies tell me ABA is the best thing since sliced bread and how many IQ points they give to children much higher functioning that my son- my son will no longer tolerate directives and so for us, for the moment, table work at least is out (we can use other aspects of ABA, but no directives).
I don't have anything against research into ABA (for example), but I do have problems with research that seeks to find what works for 'autism' because there is no such thing as autism. What type of autism are we talking about? And I have found practitioners who are welded to a particular therapy to be not as helpful as those who are open to incorporating different types. This may be something that is particularly noticeable/relevant for the severe end of the spectrum - I don't know, but needing a range of approaches doesn't seem to be unusual in the children I'm familiar with.
