The absence of a logical formal representationof the overlapping signs of child abuse (CA) is a knowledge gap that affects identification, evaluation, and intervention processes in different fields of knowledge, especiallyforensic and clinical. This study aimed to analyze through a literature review to what extent the signs and symptoms of the different types of CA present co-occurrence and overlap (intersection) between them; what isexposed as an input to propose a logical formalrepresentation.

Twenty-six articles published from 2017 to October 2022 were systematized. The results show the challenges that professionals have in the evaluation processes and the establishment of the causal link, given that sharing the signs bet...
