Children who were sexually victimized by other minors, including inter-sibling abuse, show largely the same problems as children victimized by adults, including anxiety disorders, depression, substance abuse, suicide, eating disorders, post traumatic stress disorder, sleep disorders and difficulty trusting peers in the context of relationships. The victim often has distorted beliefs about what happened to them, sometimes even thinking they were the initiator or that they went through the act voluntarily.
Major factors that affect the severity of symptoms include the use of force or coercion, the frequency of the abuse, and the invasiveness of the act. An increased risk of victimization later in life has also been reported.
