A questionnaire survey (mapping) of day hospitals in the Czech Republic was performed within the framework in an international multi-centric study EDEN (European Day Hospital Evaluation) in collaboration with the Association of Day Hospitals and Crisis Centers. The survey was done since January 2001 to May 2002. From the 35 dispatched questionnaire, 24 were answered. The following observations belong to the most important results: the most frequent functions of day hospitals include: providing psychotherapy, social rehabilitation and supplementing outpatient care. The psychoanalytical, social psychiatric and the case-oriented conduction model, respectively, were most frequent among the therapeutic models. A psychiatrist with psychotherapeutic quantification was leading the day hospital in the cases, a psychologist with psychotherapeutic qualification in seven cases, two day hospitals were headed by a clinical psychologist and a nonerudite clinical psychologist and another professional (social worker) was the head in the five remaining day hospitals. The most frequently used therapeutic method was group psychotherapy, followed by ergo-therapy, community and art therapy, respectively.
