Polygraph Testing


The polygraph examination is conducted using a LAFAYETTE LX4000 computerized polygraph instrument, which measures respiration, galvanic skin response and relative blood pressure and pulse. There are several usages for polygraph testing for post-conviction sex offenders:

Instant Offense – This format is used to determine whether the original crime was actually committed by the subject. Denial or rationalization of this crime, if actually committed, hinders appropriate treatment from being provided.

Sexual History Disclosure – Appropriate treatment can only be successful if the subject’s complete sexual history is disclosed to the treating psychologist. This format is used to verify whether the subject has withheld pertinent information from his/her background.

Monitoring Testing – An important aspect of the monitoring program is to verify that the subject has not committed new sexual offenses while in the program. This format is used for exactly this purpose.

Maintenance Testing – This format is used to determine any issue related to parole, probation or therapy of specific interest to the psychologist or parole/probation officer. Some typical uses for this exam would be to determine whether the subject has been in contact with children in violation of parole/probation guidelines, has viewed pornography, has had any contact with a previous victim, or is “grooming” anyone as a new potential victim.
