'The best use of TEACCH is constantly assessing and fading the support measures very gradually add the individual progresses, just as in ABA.'
Yes. But I've never seen any version of TEACCH that does this. In it's pure form it is about adapting the environment so that the child requires little support from other people in order to complete tasks.
So for example, with toileting there can be a visual 'ladder' of the tasks required in the order in which they must be completed. 'Shut door, undo popper, pull down trousers, pull down pants, sit down, do what you need, stand up, wipe, pull pants up, pull trousers up, do up popper, turn on tap, put soap on hands, rub together, wash soap off, turn of taps, dry hands, open door.
As routine established you can then fade some aspects of the 'ladder' can then be 'take down trousers and pants, do what you need, pull up trousers/pants, wash hands' and maybe eventually not needed.
It does have research and evidence base in that it sets out to do what it achieves. When it first was developed it made huge differences to the quality of life of children and adults with autism
The problem I have is with a)the way it is implemented in the UK, b)the fact that it hasn't been updated using latest research, since the 1970s, c)the fact that there is research now for more effective interventions that don't cost any more, d)the fact that it is the preferred method of intervention because it is cheaper in the short term to have a child dependent on pictures than resource their intervention with other people, which reduces their opportunities for interaction and practising of getting their needs met through social interaction.
But the main aspect of it that I don't like is that TEACHH proper is claimed to be delivered but the reality is simply that a TA is given a laminator and told to make some visual supports, particularly in mainstream settings, without any training on what, how, and how to move the child on both progressively and away from visual supports.
I don't like the fact that TEACHH approach seems to be accepted as a cradle to grave approach with no target to reduce the intervention or stop it.
