The Swedish government assigned SBU to assess the effects of methods used to treat people who have committed, or are at risk of committing, sexual offences against children. Concurrently, the Swedish National Board of Health and Welfare was assigned to survey the use of such treatments in Sweden.
This systematic literature review scrutinises the scientific evidence for preventive medical and psychological interventions directed at offenders. We identified major weaknesses in the scientific evidence, e.g. regarding the largest category of offenders; adult males. In the absence of findings from reliable research, a reasonable treatment and follow-up strategy might be to reduce sex crime-specific risk factors, e.g. sexual preoccupation, in offenders having the highest risk of recidivism.
