**11. Conclusion**

The development of a new intervention is an exciting process that might take several years. Continuous practical research in the form of pre- post measurements has shown positive results and a publication about this practical research is in progress.

This illustrative case study of one of the first follow-up interviews, four years after the intervention, is promising. This young adult with Asperger syndrome has shown no signs of regression at all after ending the cognitive training. On the contrary he describes how he has been able to use his newly-acquired skills for his personal development and self-determina‐ tion.

Future research is necessary and most welcome to explore the mechanisms that may underlie the improved daily function that has been observed in the children and adults with autism who have participated in our practical research. I can only speculate that for most individuals with autism, one or more components used in this multimodal ReAttach approach may lead to reliable improvements.
