Method: A literature review with both quantitative and qualitative articles was selected. Eleven articles were analysed for differences and similarities. The result of the analysis was divided into three themes and seven subthemes.

Result: The result shows that of those who participated and was included in the studies, the majority stated that they did not dare to tell anyone about the sexual abuse in their childhood.

Conclusion: When the perpetrator of sexual abuse is a parent, the child is exposed not only to the abuse but also for betrayal. Studies show that children who have been exposed by a parent feel more betrayed than those who become victims of an unknown perpetrator.
