[Effectiveness of a systematic treatment model in an inpatient department of child and adolescent psychiatry].

This is a report on the findings of the effectiveness of the "Viersener Modell", a inpatient systemic child psychiatry model. The therapy effects were recorded, by means of self and therapists assessment, in several relevant areas of change. The index clients (ic) show typical characteristics of a child psychiatry population. The ic (n = 43) and also their parents (37 mothers and 22 fathers) showed significant improvement on the level of psychiatric symptoms, individual problems and in general experience and behavior. The psychiatric symptoms that were conspicuous by both ic and parents at the beginning of therapy, were mainly inconspicuous at the end of the treatment (effectsize (es): icfemale, n = 28 = .82, icmale, n = 15 = .22, motherswithout partner(accompanying) = .20, motherswith partner(accompanying) = .44, fathers = .44). There was no essential improvement in the quality of the couples relationship, on the other hand the relationships were not clinically conspicuous at the beginning of therapy. Family members and therapists assessed quality of the treatment results and process mainly in accordance with our hypothesis. While the therapists noticed a significant improvement in the functioning of the family relationships (es = .87) at the end of the therapy, the parents (reported no difficulties in family functioning at the beginning of therapy) reported no essential improvement of family relationships in the follow-up questionnaire (n = 32). The improvement of the problems and the assessment of the quality of the treatment results remained stable over an eight month period.
