[Systemic-psychodynamic model for family evaluation]

In this paper a family evaluation instrument called systemic-psychodynamic family evaluation model is described. Also, the second stage of the validation study of this instrument is presented (which deals with the inter-observers variation). Twenty families were studied. They were assessed always by the same interviewers designated as experts. They are all family therapy specialists and their assessment was used as the evaluation reference standard or "gold standard". The observers were psychiatrists without previous training in family therapy. For the purpose of the interview, both experts and observers were blind to the medical diagnosis of the patients. During the first stage of the validation study the observers did not have a reference guide which resulted in a low concordance rating. For the second stage, a 177 item guide was used and a considerable increase in the concordance rating was observed. Validation studies like the one used here are of considerable value to increase the reliability and further utilisation of evaluation instruments of this type.
