It's the 'gold standard' for diagnosing autism/ Aspergers/ ASD, in conjunction with a parental interview and/ or questionnaire to get a feel of the history.
It stands for Autistic Diagnostic Observation Schedule and it's worldwide renowned for being the closest thing to scientific that you can use in this sort of disorder's diagnosis. It's a standardised series of activities, and for my son, was videoed and had one psych doing the test and me, his psychiatrist and 2 other mental health people in the video observation room watching him and the psychiatrist doing the test.
The idea is that they do the same tasks with every child in the same order and in the same way, and they know what a 'normal' child would do if they said 'what makes you happy?' and what an autistic child would do.
It measures eye contact, gestures, facial expressions, quality of speech, ability to start and carry on a conversation and other stuff like that. It tests how well they communicate and interact.
My son was asked to complete a puzzle, make up a story using toys, play with toys with the tester, play with toys by himself, read a book with the tester and talk about how the characters might have felt, describe a picture, talk about what made him happy/ sad/ cross/ lonely, who his friends were and why they were his friends (couldn't do any of the emotional ones), show the tester how he does his teeth and other stuff I've probably forgotten! It lasted over an hour and was quite hard for him to cope with so he kept doing all his little rituals that he always does at CAMHS - moving the furniture, opening the doors and windows, turning the lights on and off etc.
It was really clever and really revealing to watch e.g. the tester said, to start a conversation, I went on holiday this summer. Now I'm guessing most kids would ask where she went or some other question, but J said @I go on holiday in the summer'.
I think this is probably the next step for your son, Bonkerz, as they are assessing him this month aren't they?
Ancientmiddleagedmum - I won't give up, BUT I don't really know what the next step is! The psych says that anger management/ CBT wouldn't really help and he's a bit old to start ABA now (plus could never afford it and the LEA wouldn't pay for it!)
