Relationships and Fidelity issues

When trust is lost in a relationship, it could takes years to recover, if ever. In many cases the evidence of adultery is not definitive, so the only way to find out the truth is through polygraph testing.   Click here for more information

Therapeutic Disclosures and Sex Addiction

This is a variation of a “Statement Verification” exam in which the Examinee (person being tested) prepares a document ostensibly to disclose (in writing) to his/her partner any acts or conduct the partner might be concerned about.  The polygraph is then used to verify the content of the Disclosure.  This method is typically used in the Therapeutic Process after the Examinee has already made admissions of infidelity, or other unapproved behaviors, and is attempting to verify the full extent of those behaviors.  Since this is a multiple issue test by definition, results will not be as reliable as with a single issue exam, but it often the only way to resolve multiple issues simultaneously.  Diagnosed “sex addicts” are frequently administered a Therapeutic Disclosure exam as part of their treatment program.  This Disclosure should include a numbered list of specific disclosures and denials, and should be signed and dated.  Care must be taken not to include subjective statements in the Disclosure, such as “I love my spouse,” “I am dedicated to saving my marriage,” “I regret what I did,” or “Here is why I did this thing.”
