The aim of the paper is to demonstrate progress of the works on the Polish version of SCORE-15 and the results of the preliminary data analysis of changes in the process of family therapy, obtained with this tool. The works on the Polish version, ongoing since 2010, were inspired by the Research Committee European Family Therapy Association EFTA. Since the Polish version of SCORE-15 will be made public and published on EFTA website in the near future, therefore, it is important that people interested in the tool know the context of its development. Methods. The Polish version of SCORE-15, the tool designed to examine the process of family therapy, was used. Results. The comparison of the results obtained by family members before the frst family session and before the fourth one and psychotherapists’ assessments show that the percep- tion of the weight of the problem with which the family members came to therapy is indeed signifcantly lower already after three sessions of family therapy. Additionally, the obtained results show great coherence of the assessment of the family therapy progress in families and their therapists. Conclusions. The preliminary analysis of data obtained during the research project conducted in Outpatient Family Therapy Clinic, Department of Adult, Child and Adolescent Psychiatry, University Hospital in Krakow and in Laboratory of Psychology and Systemic Psychotherapy, Department of Child and Adolescent Psychiatry, Jagiellonian University Medi- Psychiatr.
