摘要：Background: The purpose of this study was to analyze the co-occurrence of adult and child abuse based on the reports collected from the Polish police and social welfare institutions. Methods: The study involved data concerning 468 households in Szczecin (Poland) inhabited by children where acts of violence between adults took place. The presented data refer to the years 2012-2103. The data came from so called Blue Card files, i.e. documents issued by the police and social workers in cases of domestic abuse, providing information about its forms, perpetrators, and victims. Results: Domestic violence usually occurs between spouses and cohabitees (78%). The perpetrator was usually a man (88%). Violence usually lasted from 1 up to 3 years (30.0%). The most common forms of physical abuse against adults and children included pushing (79.5% of adults, 22.4% of children) and hitting (64.7% of adults, 16.6% of children), and psychologically abusive behaviors were mostly insults (91.9% of adults, 27.5% of children) and criticism (79.1% of adults, 21.5% of children). This work has shown that the longer the psychological abuse between adults lasts, the greater probability is that it will also be used against children. Child abuse is also associated with putting up resistance to the police by perpetrators. Conclusions: Summing up, in households where violence between adults is observed, actions should be taken to prevent violence against children
