Pedophilic transtorno is characterised by a sustained, focused, and intense padrão of sexual arousal—as manifested by persistent sexual thoughts, fantasies, urges, or behaviours—involving pre-pubertal children. In addition, in order for Pedophilic transtorno to be diagnosed, the individual must have acted on these thoughts, fantasies or urges or be markedly distressed by them. This diagnosis does not apply to sexual behaviours among pre- or post-pubertal children com peers who are close in age.
