For the successful prosecution of child sexual abuse, children are often required to provide reports about individual, alleged incidents. Before and during investigations of sexual abuse, it is likely that children are exposed to experiences that may affect the length, accuracy, and structure of their allegations, such as multiple incidents of abuse, informal interviews with parents or teachers, conversations with other victims, televisions programs, magazines, dreams, and daydreams. In addition, children may also experience similar, abusive incidents on multiple occasions. Exposure to related events can strengthen children’s memories. However, children’s report of individual incidents can also be contaminated when they experience other events related to the individual incidents and/or when they have similar repeated experiences. This article reviews research on the positive and negative effects of these related experiences on the length, accuracy, and structure of children’s reports of a particular incident. Several recommendations are presented for forensic interviews of children which explore different methods of questioning children. References
