Regressed – Typically has relationships with adults, but a stressor causes them to seek children as a substitute. Morally Indiscriminate – All-around sexual deviant, who may commit other sexual offenses unrelated to children. Naive/Inadequate – Often mentally disabled in some way, finds children less threatening. Preferential – has true sexual interest in children. Mysoped – Sadistic and violent, target strangers more often than acquaintances. Fixated – Little or no activity with own age, described as an "overgrown child". Causal factors
Causal factors of child sex offenders are not known conclusively. The experience of sexual abuse as a child was previously thought to be a strong risk factor, but research does not show a causal relationship, as the vast majority of sexually abused children do not grow up to be adult offenders, nor do the majority of adult offenders report childhood sexual abuse. The US Government Accountability Office concluded, "the existence of a cycle of sexual abuse was not established." Before 1996, there was greater belief in the theory of a "cycle of violence", because most of the research done was retrospective—abusers were asked if they had experienced past abuse. Even the majority of studies found that most adult sex offenders said they had not been sexually abused during childhood, but studies varied in terms of their estimates of the percentage of such offenders who had been abused, from 0 to 79 percent.
Child sexual abuse victims report almost four times as many incidences of self-inflicted harm. Sexual assault among teenagers has been shown to lead to an increase in mental health problems, social exclusion and worse school performance. A well-documented, long-term negative effect is repeated or additional victimization in adolescence and adulthood. A causal relationship has been found between childhood sexual abuse and various adult psychopathologies, including crime and suicide, in addition to alcoholism and drug abuse. Males who were sexually abused as children more frequently appear in the criminal justice system than in a clinical mental health setting. A study comparing middle-aged women who were abused as children with non-abused counterparts found significantly higher health care costs for the former. Intergenerational effects have been noted, with the children of victims of child sexual abuse exhibiting more conduct problems, peer problems, and emotional problems than their peers.A specific characteristic pattern of symptoms has not been identified, and there are several hypotheses about the causality of these associations.Studies have found that 51% to 79% of sexually abused children exhibit psychological symptoms. The risk of harm is greater if the abuser is a relative, if the abuse involves intercourse or attempted intercourse, or if threats or force are used. The level of harm may also be affected by various factors such as penetration, duration and frequency of abuse, and use of force. The social stigma of child sexual abuse may compound the psychological harm to children, and adverse outcomes are less likely for abused children who have supportive family environments.
