What helps one may not help another
Whilst its good to offer both, you should never put the distance of a computer as an advantage to encourage aspergers syndrome or simillar! Replacing the 'real thing' with a virtual alternative is like a virtual machine replacing the physical computer you run it on! CAN'T BE DONE!
Studies all around the world have shown kids of the younger generations spend too much time on the computer as it is, whilst its a good use of time on the computer, how can one also ensure it is confidential and 'secure' from virus ridden/monitored devices!?
WIll kids realise the dangers of multiple sources of counselling etc? What would prevent them from doing that, or a copycat providing such a service!? Trust is important...
Would group therapy 'come close to the kind of treatment delivered in 1 to 1 CBT sessions'... Lets not become naive when it comes to mental health! Think of the children and dont encourage it!
