The average length of admission to the clinic is between 4 and 6 months. Shorter admissions for observation and diagnosis are possible. The nucleus of the treatment is formed through a community under the guidance of sociotherapists-nursing staff. Following a short orientation phase, the treatment begins. This treatment consists of psychotherapeutic and psychiatric methods, in which use is also made of creative, psychomotor and music therapy.
Social work provides projects in which social orientation is of central importance.
As far as possible, partners, family members and other people who are important to the client are included in the treatment. For treatment in De Vonk it is important that the client is prepared to learn Dutch, is able to attend to his own daily physical care and is prepared to bear some responsibility in respect of the other members of the community.
