The review included studies in which all victims were 18 years of age or younger and which reported quantitative results. Case studies were excluded as were studies that included adult victims or addressed only a special population. The majority of the studies were published during the past 5 years. The most frequent symptoms were fears, post-traumatic stress disorder, behavior problems, sexualized behaviors, and poor self-esteem. However, no single symptom characterizes a majority of sexually abused children. Some symptoms are specific to certain ages, and approximately one-third of victims have no symptoms. Factors affecting the degree of symptomatology include penetration, the duration and frequency of the abuse, the use of force, the relationship of the sex offender to the child, and maternal support. About two-thirds of the children show recovery during the first 12-18 months. The findings suggest the absence of any specific "sexually-abused-child syndrome" and no single traumatizing process. Results indicate the need for theory testing and methodological development in studying these issues. Tables and 84 references (Author abstract modified)
