Pedophilia (or paedophilia) is a psychiatric disorder in adults or late adolescents (persons age 16 and older) for whom prepubescent children are the primary or exclusive sexual object of their sex drive. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM), pedophilia is a paraphilia in which a person has intense and recurrent sexual urges towards and fantasies about children they have either acted on or cause distress or interpersonal difficulty.
The disorder is common among people who commit child sexual abuse; however, some offenders do not meet the clinical diagnosis standards for pedophilia. In strictly behavioral contexts, the word “pedophilia” has been used to refer to child sexual abuse itself, also called “pedophilic behavior”. In law enforcement, the term “pedophile” is loosely used without formal definition to describe those convicted of child sexual abuse or the sexual abuse of a minor, including both prepubescent children and pubescent or post-pubescent adolescents. An example of this use can be seen in various forensic training manuals. Researchers recommend that this imprecise use be avoided. In common usage, the term refers to any adult who is sexually attracted to young children or who sexually abuses a child or adolescent minor
