There are four main types of sex offenders polygraph testing: specific issue testing, sexual history disclosure, maintenance and monitoring examinations. It is scientifically proved that polygraph examinations improve the protection of victims and the prevention of future victimization. Sex offenders make more disclosures regarding their sexual history and also their future behaviour is more predictable between periodic examinations. Examples of researches and practical usage of polygraph in the United States and Great Britain were provided. Applying this method results in better risk management and reduces recidivism.
