This review shows some studies about the value of children’s drawings as a means of communication. This review is based on the literature which focuses on drawings produced by children who have experienced traumatic events, especially sexual abuse. Many researches underline that it is often difficult for children to give an account of the abusive events, because of the pain aroused by the recovery of traumatic memories. Drawing could allow children to externalise the inner world: it could be useful both a clinical setting, to help the elaboration of trauma, and in Court, to simplify children’s statements. Some Authors try to find out some indicators of abuse that could help specialists in interpreting children’s drawings. This work includes both these kinds of studies and a brief review of graphic tests most useful in working with sexually abused children.
