After one year the group moves to another collective connected to a folk high-school. The success rate of this rehabilitation programme is said to be over 75 per cent, but it is difficult to discover what this figure is based upon. The Hassela experiment has inspired a similar kind of institution in Norway, the Tyrili Collective. In some cases compulsory treatment will last for two months, in other cases the treatment may be prolonged by a further two months. At present there is serious debate in the Scandinavian countries on this proposal in particular, and on compulsory treatment in general.
Some professional groups are in favour whereas others are against the idea.
It is dangerous to make generalizations about the model of compulsory treatment. The Hassela has been used for quite young people under the law of child care. The Hassela programme is designed for a three-year period of education and training. The proposed Swedish law talks about two, perhaps four months of compulsory treatment. The Hassela programme was established and is run by an experienced, charismatic personality.
