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.
Polygraph exams are used extensively for relationship issues. This is one area of testing where experience makes a big difference. The wording of test questions is critical to a successful exam, since many words can be interpreted differently by different people. See FAQ #0805 for a list of Question Design Rules.
In 2012, GPN Owner Michael Martin published the first textbook for Domestic Issue polygraph testing. All of the examiners in the Global Polygraph Network™ are experienced and qualified to provide these types of exams.
This format is used to determine whether one partner has had sexual contact with anyone else besides his/her partner. Other related items may include questions about dating, kissing, having contact with "exes," placing personal ads, visiting strip clubs, etc.
This format is appropriate when a partner needs to verify aspects of his/her partner's background, such as sexual history, drug or alcohol habits, gambling, health issues (particularly STD's), and excessive financial obligations.
Not all "cheating" requires physical contact. Polygraph can be used to determine the extent of "sexual" activities conducted over the internet, such as visits to pornographic sites, dating sites, sexual chat rooms, interactive sexual web sites, or having "cybersex" (sexual chat) with someone who is not his/her partner.
