Polygraph
How effective is the use of the polygraph in the treatment of sex offenders?
Literature Review
Found that the polygraph was an effective tool in sex offender management and reoffending
Validation is questionable
Forensic Research, Inc. study gathered 8 research projects run since 1980 to evaluate the validity and reliability of polygraph testing
Post-Conviction Polygraph in the Community and Court: Raising the Bar on PCSOT examiners - Blackstone
Research conducted on the offenders opposition, willingness and acceptance of the polygraph
Participants opinions varies
Method used JSBP survey
Supervision and Treatment of Juveniles with Sexual Behavior Problems – Brandes & Cheung
High rate of accuracyLack of uniformity
The Limits of the Polygraph – Faigman, Feinberg and Stern
Polygraph important tool in gathering prior history
Verify the sex offenders truthfulness in the therapeutic process
Polygraph should be used as one facet of the treatment
Sex Offender Treatment: Reconciling Criminal Justice Priorities and Therapeutic Goals. – Farkas & Miller
Significant increase in disclosure
Issues of extracting false confessions
Recent Analysis shows 40% success
Increase between 60% -196% in disclosures of victims and risky behavior
The Current Role of Post-Conviction Sex Offender Polygraph Testing - Kokish
Study conducted in Oregon in 1988, 1994, and 1999 found similar results in disclosures of polygraphed individuals
There are marked increase in disclosures of polygraphed sex offenders
Anticipation of the polygraph test increases disclosures.
Increased disclosure of sexual histories among polygraphed individuals
Polygraph Testing Leads to Better Understanding Adult and Juvenile Offenders – Hindman & Peters
Argues the use of the polygraph on its lack of value in detecting lies
In 2002 it estimated that sex offenders were tested at a rate of 70% in community based programs
Lacks theoretical basis
No methodologically sound studies to test the validity or accuracy
The Case Against the Use of Polygraph Examinations to Monitor Post Conviction Sex Offenders – Ben-Shakhar
Self-reporting increases with the use of the polygraph
Analyzed a test that spanned over a two year period
Increase of new disclosures that would be beneficial to treatment
The Case for Polygraph Testing of Sex Offenders - Grubin
Created a study using participants who were already in a treatment program
The study was conducted on two separate occasions with the same participants
Found that offenders reported fewer offenses at the second testing
Sex offenders in a small study found that polygraph testing was beneficial in reducing reoffending
A Preliminary Study of the Contribution of Periodic Polygraphed Testing to the Treatment and Supervision of Sex Offenders – Madsen, Parsons and Grubin
Found that the polygraph obtains much more disclosures than any other self-report measure
Issue of false-negative and false-positive findings
It has limitations
Application of the Polygraph Examination in the Assessment and Treatment of Internet Sex Offenders – Robilotta, Mercado & Degue
The polygraph induces greater disclosure rates
Arguments regarding validity and accuracy of the polygraph in terms of reliability
Links in the Studies
Lack of conformity and uniformity among testing procedures
Additional research should test re-test reliability
Not enough data to prove the polygraphs effectiveness
Recommend to further examine sex offender ability to use counter measures
Use long-term study in regards to conformity
Limitations to Current Research and Recommendations
